Starship is like AI/LLMs in that success would revolutionize the world, but technological failure is very possible. And despite the confident predictions on the internets, we don't know which it's going to be.
After the Shuttle program ended in failure, work on reusable launch systems stopped for decades. A similar thing would happen if Starship fails. Space would remain the province of the military and large governments.
Today it costs ~$3,000 per kilogram to put something in orbit (on a SpaceX Falcon 9). Starship aims to lower that to $10 per kg. That's totally crazy, but even if it could get it down to $300 per kg, that would revolutionize access to space.
Data centers in space, biotech manufacturing, and maybe even asteroid mining and energy generation become practical at those prices. To say nothing of telecommunications, remote sensing, and global navigation--all become much cheaper.
And, of course, that drops the price on all the cool science/exploration goals that we always talk about: massive space telescopes, regular probes to all the planets, and crewed exploration.
We're literally at an inflexion point between two possible futures and we don't know which it's going to be. If I were younger I would absolutely try to work at SpaceX to help tilt the chances.
> After the Shuttle program ended in failure, work on reusable launch systems stopped for decades. A similar thing would happen if Starship fails. Space would remain the province of the military and large governments.
I really don't agree with this take.
It may appear as if SpaceX is the only game in town, but in reality a lot of this technology is commoditized now, and space is as diversified and vibrant as ever.
The starting point today is very different from the post-Shuttle environment. If Starship fails, it is unlikely to be for pure technology reasons and something else will take its place with perhaps better product-market fit.
SpaceX is a symptom, not the cause.
The true dangers to all of these lofty human enterprises are geopolitics, domestic political destabilization and environmental collapse.
I would actually argue that Apollo and the space race damaged reusable launcher projects more than the Space Shuttle. Before the mad scramble to the Moon there were many interesting infrastructure projects and incremental manned mission planned as well as partially or fully reusable launcher or variants of existing expendable launchers.
Then everything that was not contributing to MOON ASAP was thrown away & massive spending on space hardware essentially normalized. The end result (Apollo) was impressive and achieved the goal (first on the Moon) - but was also totally unsustainable, resulting in a big crunch and a lot of setbacks and slowdowns.
Another contributing factor has been military involvement - again, wee need that milsat on orbit and we need it now, costs be damned. ICBMs not being exactly reusable does not help. Even the Space Shuttle design being perverted into its partially reusable clunky form can be traced back to military requirements.
Great point! There were many reusable projects in that era, but Apollo budgets consumed everything else.
I still think Shuttle could have worked, if it had been cheaper to evolve it.
Elon's focus on Starship is to make each iteration as cheap as possible, which means they can radically evolve the design without fear. Think of the (recent) switch to hot-staging or the evolution of Raptor.
If Shuttle had been able to evolve like that, I think they could have gotten the cost down. If you think about it, Starship is basically just Shuttle with the orbiter stacked on top of the booster and with propulsive landing.
> I still think Shuttle could have worked, if it had been cheaper to evolve it.
I doubt it. It's a gigantic kludge that isn't fixable.
For example, the requirement that it land like an airplane meant it needed wings, landing gear, and a full set of flight control surfaces. None of that is useful apart from the landing, and yet it is necessary to push it all into space and re-enter it.
I once emailed Homer Hickam about it, and he was kind enough to reply and said he'd argued the same thing.
The shuttle is the only rocket system that put part of the rocket above the payload. Were it not for that fatal design flaw, both fatal flights would have been survivable. The first because the explosion would have done less damage. The second because there would have been nothing above the shuttle from which something could have fallen.
I think @WalterBright is probably right and that the Shuttle design was too compromised to be fixable.
Stacking the orbiter on top of the external tank is a non-starter, IMHO. Obviously you'd have to add engines at the bottom, but now your cost goes up unless you plan on recovering the external tank (and how do you do that?).
And now you need another fuel tank for the orbiter, right? Do you extend the orbiter so it can fit an internal fuel tank? Or do you remove the engines and move them to a separate disposable stage?
None of that would have been a serious concern had the shuttle actually met any of it's re-usability claims. It doesn't matter that it costs a bit more in fuel and initial outlay for the orbiter if you actually could turn it around with little effort or cost in a couple weeks.
Having to inspect each and every tile after every trip because they basically didn't work like initially designed was the primary failure of the Shuttle program. It also wasn't nearly safe enough, primarily due to a shitty management culture that was taking over America (and is still currently in power in nearly every business).
The thermal tile technology was for some reason believed to be dramatically easier to design, engineer, and manage than it ever came to be in reality. I'm not convinced that Starship has "solved" the problems inherent in tile systems.
That assessment massively underestimates the impact of all that machinery needed to fly it, in terms of design, cost, maintenance, etc. It cannot be wished away.
That's sort of a fallacious argument though because you could say the same thing about every part of a spacecraft that is used only for the return phase of its mission.
It might be more accurate to say that the ratio of mass for re-entry equipment to the entire craft mass is too great.
But with that said I think that the ultimate failure of the shuttle was that the design wasn't amenable to low cost maintenance. A spacecraft could have a crappy payload to orbit as long as it's cheap to maintain and use with quick turnaround.
I have a feeling that should Starship succeed this will be the case with it and it will end up having a substantially lower payload than intended but will make up for it with a design that's cheap to build and maintain.
I disagree. If Starship fails, the most likely reason will be technological. Either they can never get the heat shield to be reliable, or they can't get cost down below Falcon 9 (meaning, refurbishment costs are too high).
And if it fails, who will spend billions on a new vehicle?
Stoke Space: They are working on Nova, which is designed for 2nd-stage re-use, and they've got a novel architecture. But they are not well-funded and if Starship fails, it is likely that investor sentiment will shift away from full reusability (you know how investors are). And even if they succeed, their current vehicle can only get 3 tons to orbit. That means each launch must cost less than $1 million to get to the $300/kg target. In contrast, Starship can loft 100 tons, so it can cost up to $30 million per launch and still hit the target.
Blue Origin: They are still working on 1st stage re-use, and even assuming they get that to work next year, they are at least a decade away from testing 2nd stage re-use. And their current designs don't have any of the cost-savings in Starship (like launch-tower catch).
And that's it! There are no other companies seriously working on 2nd-stage reuse.
If Starship fails, there will not be another contender for cheap flights to orbit for decades.
> Either they can never get the heat shield to be reliable, or they can't get cost down below Falcon 9 (meaning, refurbishment costs are too high).
There are a lot of other potential technological problems (dozens of engines, stainless steel construction, the belly flop maneuver, etc). Ultimately if Starship would were to fail for technical reasons, it would only indicate the particulars of Starship's implementation don't work. Starship is not the only (or even in my opinion the best) way to achieve full reusability. And partial reusability, which just a few years ago was considered radical, has already been so firmly proven that just about everyone is doing, or trying to do it. The idea of "don't destroy this extremely expensive vehicle after only a single use" won't die for as long as people can see expenses on their books.
If anything, the alternative approach, making a low cost, mass producible rocket has been abandoned, possibly pre-maturely.
Rocket Lab tried the alternative: low-cost, mass-produced expendable rockets, and Peter Beck famously ate his hat when they pivoted to reusable.
Partial reusability won't get the cost down to the ~$100/kg range. And it definitely won't do that and still loft ~100 tons to orbit.
Falcon 9 can get 15 tons to LEO for $45 million, and that's already the lowest price on the market. To hit $300/kg they would need to build a 2nd-stage, launch, recover (on a drone-ship) and refurbish for $4.5 million. That's just not going to happen.
There are only two companies that are actively building hardware for 2nd-stage reusability: Blue Origin (which doesn't even have a prototype yet) and Stoke (which has a max 3-ton payload). If Starship fails, we are not getting $300/kg orbital costs for 1-2 decades minimum.
I agree that Starship has lots of other potential technological blockers (although fewer each attempt--I never thought tower-catch would work the first time). But no other designs are even close to fulfilling the promise of low-cost orbital launch.
AFAIK there is a bunch of Chinese startups pitching some fully reusable designs and/or ready to clone something that works. There is already some Falcon 9 like first stage reusable booster prototypes in development.
The thing is, there is no demand to get that much stuff into space.
Falcon 9 has massively brought down the cost per orbit, and even with the whole world as a captive market, every university in every country putting up cubesats, they still don't have nearly enough payloads to make the economies of scale kick in. Hence Starlink. The majority of SpaceX payload mass has been Starlink, something nobody was even asking for. 300+ launches.
And the idea to reach the economies of scale for Starship is... Even more Starlink. How much Starlink could we possibly need? When will humanity come up with another use for this glut of payload capacity?
Even with the Artemis deadline looming large, SpaceX are still pushing this Starlink angle for Starship, it's nuts
Demand takes some time to ramp up, especially with quite expensive and complex stuff like Satellites. SpaceX is now even launching competing constellation comsats (project Kuiper), private manned space missions and there are quite a few manned space station projects under development that would be basically unthinkable without the cheaper lift Falcon 9 provides.
As for "How much Starlink could we possibly need?" I think the answer is simply "YES". Even when you possibly somehow satisfy all your Internet access customers, you can start adding other services, like mobile phone coms (already in progress) or maybe imaging or hosted payloads.
Yeah - while real space development will use 99% of local resources eventually, the cheaper we can get stuff to LEO the quicker we can get things going. Not to mention lifting any complex stuff & humans, that which simply not be available otherwise until much more stuff is operational in space.
Haven't the economies of scale already kicked in a little? Starlink is profitable. I'm not sure if spacex minus all starship costs is profitable. I'm pretty sure they're quite good at building them faster, better, and for less now. Please show me otherwise. I guess you could call that more learning curve, but that's a fuzzy line.
I guess overall I don't understand your point. What does it matter that the majority of their payload mass was their own? And nobody asking for something is certainly not the same thing as nobody wanting/needing it. See: cars, computers...
Starlink now exists and I'm quite certain people love it and rely on it. Wouldn't exist without falcon 9. Starlink basically solved the last mile problem, surely you'd agree rural folks having access to Internet is a good thing?
They made their own demand for falcon 9, with that scale bringing down costs enough to raise demand for basically every research org needing satellites to contract with SpaceX.
I don't think we can definitively predict the demand either way for payload at $300/kg or whatever without first getting there, but Jevons might have some ideas.
Demand comes at a curve, the cheaper you make it, the more demand there will be. The demand for satellites and eventually human travel is practically infinite if the cost is low enough.
If Starship cuts cost to orbit by at minimum 1/3 and at maximum 1/100th demand will skyrocket (pun intended) either way.
Starlink is both a successful commercial service making money hand over fist and a vital strategic asset for the United States. Put simply its one of the most transformative infrastructure projects of the 21st century. SpaceX found a winner and is doubling down on it I don't blame them.
Sure, not directly. But most of that is imaging and communications payloads, and the vast majority there is being purchased by militaries and intelligence agencies.
After the Challenger disaster (1986) it was clear that the Space Shuttle was never going to accomplish its cost and reliability goals. The US military had bet everything on the Shuttle, so it needed a new launch vehicle. The one clear requirement of the new launch vehicle was that it had to be expendable. In fact, the name of the program was "Evolved Expendable Launch Vehicle"[1]
Remember also that when SpaceX started to develop Falcon booster reuse in 2011, every major aerospace company said that reusable vehicles would never make economic sense. Even after the first Falcon 9 recovery and re-flight, most aerospace companies thought reusability was a dead-end and that belief came from the refurbishment cost that Shuttle had to go through.
I count from 1994 (start of EELV) to 2021, when NASA launched astronauts on a reused booster and Peter Beck famously fulfilled his promise to eat his hat if Rocket Lab ever worked on a re-usable launch vehicle.
SpaceX started with the business plan of low cost, mass producible single use launchers. Falcon 9 was not designed with any level of reusability in mind. There was a major redesign to add landing hardware, but the whole reason for Starship being a totally new design was the reusability that a Falcon "super-heavy" derivative could never achieve.
Good point! I don't think Falcon 9 is large enough for full reusability.
I don't think Stoke's first vehicle will be large enough either (beyond proving out the technology). They will eventually need to build a much larger one.
Also, Kessler Syndrome is over-feared, like the China Syndrome from the nuclear age.
At Starlink orbits, space debris renters in years, if not months. And even then, having cheap access to orbit would allow us deploy replacements quickly.
At GEO, the distances are so vast that Kessler Syndrome is much less likely (though not impossible).
In between, there is some danger, but again, cheap access to orbit gives us the possibility of clean up.
Simple: VC money. The only thing surprising to me about that is that the pitch wasn't "AI in space".
My take: The idea that heavy computing in LEO is better than sending data down to Earth sounds very naive. Starlink is great proof that the bandwidth is plentiful and the latency is good, once the equipment is modern. Definitely cheaper and easier than cooling a datacenter.
Lots of things are harder in space; maybe even everything. But it has some benefits, like abundant solar power, lots of room, and line-of-sight to large chunks of Earth.
Almost all the problems can be solved by cheaper access to space, whereas the benefits cannot be easily recreated on Earth.
Is it guaranteed to work? My point is that we don't know, despite confident assertions one way or the other. If it does work, the benefits are clear, and that's why it's worth trying.
It was a significant progress, but I won't call it "nailed it". As there was an damage or explosion on re-entry where the skirt of the starship got damaged. And we could see pretty significant damage on one of the fins.
The explosion was unexpected and (as far as I know at the moment) unexplained, but they flew the mission at the edge of the envelope, and with a variety of different materials/missing bits on purpose, to better understand where the edge is. Everything that happened (maybe even including the explosion, we'll see in the final analysis) was, as far as we know, within the plan.
The biggest can't-miss milestone was the flawless engine restart. That gives them the go-ahead to hit orbit on the next flight.
Actually existing Starlink satellites regularly bu p into each other when lobbed in benches by the Falcon 9.
They are built to tolerate that, resulting in much better launch volume and weight utilization (sats are stacked on top of each other & held in place by rods that are then released).
The Starship Starlink release demo was quite tame in comparison to that. ;-)
Is it really unexpected that an extremely hot metal pressure tank will rupture when plunged into water?
Since the ship is designed to be caught by a tower and not be plunged into water at all, it doesn't seem like this would be an issue in normal operations.
You should have seen the first tech demonstrator for the Raptor engine (the family that powers Starship). It was basically a water tower (built out in the desert, welded by people specialising in building water towers). But it flew, and it landed, and then it served as a lights & camera mount for the field for a few years.
I wonder how many potential designs they considered. You've got the mass of the doors and structure of the ship to consider, the mass of the cargo, actuators for both, the arrangement of cargo in the ship, all of which have interconnected tradeoffs.
Also add pressure management, warping of the dispenser and ship hull & thermal expansion.
And fornlong duration missions also lubricant evaporation, possibility of vacuum welding & atomic oxygen reactions if you spend long in low Earth orbit. :)
The fun thing is that as long as you have the requirements and acceptance right, this could still be solved with a garage door opener and welded rebar :-D
SpaceX has two big things going for it: Starship/Raptor factories churning them out cheap, and themselves as a paying customer in Starlink who can dogfood a risky new launch platform.
Now that they're demoed pez-dispensing v3 dummy Starlinks, I'd assume they'll start launching real ones within ~1-3 months. At that point as long as they can deliver payload to orbit and catch the booster the program is operational and they'll start switching their own Falcon 9 launches over.
The HLS timeline is definitely dicey, but whether Starship winds up being the blocker remains to be seen. Otherwise they've now succeeded enough to "lean launch" Starship with equal/better capabilities to any other existing orbital rocket, and Starlink can fund indefinite further tests/iterations on the rest of their roadmap features (which no one else has).
> I'd assume they'll start launching real ones within ~1-3 months
I think it's still a bit early for that given that they've only had one successful flight and are still testing lots of new design changes, but I think you're right that the capabilities they've already demonstrated are probably enough to make Starship commercially viable even if literally none of the other revolutionary improvements they're working on pan out.
Falcon 9 doesn't recover the 2nd stage at all, and it's already by far the least expensive rocket out there in terms of cost/kg.
Yes, although it was stated before the flight that they were intentionally flying with some heat tiles removed and with a more aggressive profile to test some outer limits.
> I'm surprised they didn't take less risks just to avoid a narrative of failure.
That's the advantage of being privately owned. "Vibes" (hah) don't matter. Public opinion doesn't matter. What matters is executing on your vision / goals. And they're doing that.
The fact that they're bringing in loads of cash from Starlink surely helps. They haven't had the need to raise money in a while, now.
They literally just took another 1.5 billion in tax payer money on top of previous billions. They are cash flow negative and only have a multi year runway
That's probably the first step on the path to stagnation.
There's a lot more eyes on them now a days, and Musk is much more well known, so it creates a lot more drama - but they've done the exact same process with everything. They even published a montage of failures [1] on the way to their first successful landing 'back in the day.' It was fiery, but mostly peaceful. They didn't even hit a shark!
Unless they took extra risks to hedge against the string of failures continuing. "Yes we blew up three times in a row, but this time we meant to do that, so it's a success" sounds an awful lot better than "We did everything we possibly could to prevent it from blowing up this time but it still did"
I'm certain they don't care about the narrative because ultimately even though yesterday was a big success some places had headlines that really downplayed it
Fin damage isn't ideal, but even if they had to replace the fins every flight, the cost would be quite low in comparison to replacing the entire second stage, which is necessary on the Falcon 9.
I think this launch showed they were very robust. Engines went out on booster and ship which they can compensate for. A small explosion and a half melted fin didn't seem to affect the splashdown sequence or target.
The flight looked good, but I was wondering if the ship splashdown burn was the ideal one or an alternate one from a damaged engine. To me it looked like they were working around a damaged engine.
The splashdown burn was specifically set up that way to test the fallback scenario for a failure of one of the inner ring engines. The fact that the ship landed almost on top of the target buoy shows it was a success.
The fins were intentional… they said on the live stream they were testing different types of tiles and missing tiles to see how the substructure would behave.
I view it differently. The ship not only survived, but also accomplished all of its mission objectives despite those issues. What this shows is that it has remarkable resilience, which is a really important considering the types of forces it will be subject to during future missions.
> And we could see pretty significant damage on one of the fin
They specifically said they're testing lighter fins to see how much they would hold. Let's not invent problems when it's an experiment that was clearly stated.
They planned a test that would subject various components to stress levels outside of the normal mission profile. The various specific failures that resulted from that may be within expectations but not necessarily planned.
In engineering you want to know that a design will not just succeed at its rated limit, but have some margin percentage of safety above that. To measure that margin often involves destructive tests.
SpaceX's development methods differ a bit from more traditional rocket development by performing some of these potentially destructive tests with full-scale articles in real flight scenarios as part of an iterative process.
I'd say it's a mixture of chaos engineering and load testing. They know what performance they need for a safe flight, but they want to know how much margin of error they've got (and how close their simulations are), and what they can do to optimise.
It's a different apporach to say the Apollo program, where they did heavy up-front analysis, at the expense of cost-efficiency, speed, and innovation. They had one-shot for a flight, otherwise that's several $bn up in flames.
Even with the last few mishaps, it's an approach that seems to be working. If you look at Starship and Falcon's journey in comparison to SLS and Blue Origin, they have done so much in such a short timespan.
In complex systems testing by perturbing the environment is the easiest, simplest and uncovers most relevant issues with design. They knew something would fail, but not necessarily what exactly or in which sequence. They can now reject or accept their hypotheses and improve their models.
For Starlink deploys (or other commercial launches) re-entry isn't too critical. Starship is still an order of magnitude cheaper than other launch vehicles even without Stage 2 re-use.
They'll need a higher bar for Artemis but frankly Starship is not the only critical bottleneck there and it's not SpaceX's main financial driver.
> "Why didn't just get it right on their first test", really? People can't even get a regex right the first time.
The comment you replied to didn't say that. And this isn't the first test.
I think their comment was reasonable. It was a successful mission that met the stated objectives and demonstrated progress. But it wasn't perfect, and there is definitely more progress to be made for Starship to be a reliable operational launch system.
It's pretty remarkable progress. Slowly but surely, they're getting it done. I predict they'll have a full working version by 2027. By 2028, they'll have regular reusable flights.
My personal estimates are similar. For anyone that followed Falcon 9 development (from the first Falcon 1 launches), it’s really similar. I remember boom after boom until one day they cracked the problem and reusable boosters became the status quo.
I got tingles when the first booster landed on the drone ship, because I knew access to space had just changed in a fundamental way.
Comparing Falcon 9 to Starship is a dangerous mistake.
First, the time frames are way off. Development of the Falcon 9 took ~5 years (2005 to 2010). The first reused booster came much later (2017?).
Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was.
Third, Starship is significantly more complicated technology-wise, being methane based. There are reasons to do this but it then requires cooling both propellants (instead of just liquid oxygen and RP-1 ie kerosene with the Falcon 9(.
Fourth, Starship has to compete with somethingg Falcon 9 never did: Falcon 9. Falcon 9 is now the most succcessful and cheapest launch platform in history. It is the reliable workhorse of the industry and relatively cheap to launch. Its reuse is proven.
Fifth, the market for Starship is unproven. We can compare it to other launch systems for heavy payloads, most notably the Falcon Heavy, which I believe has only had ~12 launches in almost a decade (compared to the 100+ Falcon 9 launches every year).
You could argue SpaceX will steer customers to Starship but there'll be other competitors (to the Falcon 9) by then.
Lastly, Starship is still so far from being human-rated. So much of the needed tech (eg refuelling in orbit) hasn't even begun testing yet. I can easily see this taking another decade at least.
> Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was
They are already reusing boosters, so it might already be cheaper than F9 before booster reuse. Once they start reusing the ships, it will be cheaper than F9 with booster reuse because F9 has to build a new second stage each launch.
> Fifth, the market for Starship is unproven
The market for Starship is proven by SpaceX itself. The Starship can add 20x the Starlink network capacity per launch as F9. There are currently around 100 Starlink launches per year, so the market couldn't be more proven.
> Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was.
The launch cost of a Starship today is high, especially if you include development costs, but Musk's goal is a marginal launch cost of ~$1M. A Falcon 9's launch price is ~$70M; Musk claims a "best case" marginal Falcon 9 launch costs ~$15M.
Yeah if those numbers are even in the correct order of magnitude Starlink will become a literal money printer. Any commercial or government launch contracts will be cherries on top. Bezos will be our only hope for affordable satellite internet.
Is it though? I'm not knowledgeable on this at all, but it _seems_ like Space X is blowing up a lot more expensive equipment compared to NASA back in the space race days. Genuinely curious how it compares and how true my outsider impression is.
It's not as expensive as it looks, Starship plus booster costs around 100 million. A Saturn V Apollo mission cost 185 million in 1969 which, according to https://en.wikipedia.org/wiki/Saturn_V#Cost, would now be a bit less than a billion dollars.
Also, SpaceX is not building rockets, they are building a rocket factory. If they succeed they will have lowered the cost of putting stuff into space by an order of magnitude. The potential rewards are huge.
Yes but at this point the upper stage is barely a spaceship. Mostly an empty shell. And they have spent $10 billion so far on something that barely flies.
R&D and prototyping is an up-front expense. Amortization over many units spreads out the costs to long term profitability. Does SpaceX have that kind of time, though? A prospective global depression would dry up the capital for funding Starship development.
There's more of a production line when building Starships, with modern mechanised tooling - much of it computerised and 100% repeatable. There's been at least 10 so far, vs only 15 Saturn V, 3 of which were ground tested.
There's absolutely loads being done for the first time here. Not least of which: running this r&d off commercial contracts instead of directly off taxpayer money.
Apollo also invented, funded and productized a lot of modern embedded computing and computer manufacturing, to keep in our lane here. Obviously SpaceX has access to a very different tech environment that yes, Apollo helped push forward.
Manufacturing the Apollo Guidance Computer (which wasn't in the rocket per-se, but was wired up to it and could fly the rocket in certain scenarios) alone consumed around 40% of the US' entire IC production capacity at the time.
Whenever we talk about space flight, this movie quote comes to mind: "You know we're sitting on four million pounds of fuel, one nuclear weapon and a thing that has 270,000 moving parts built by the lowest bidder."
Starship has considerably fewer moving parts. And googling 'evolution of raptor engines' gives you some pretty stark images on how simpler things look, in principle.
I watched the Martian again the other day and I marveled about how much has changed. With Starship progress, almost none of the plot really makes sense (bespoke vehicles and payloads etc). The first mars expeditions will probably be stocked with a thousand tons of gear, enough to easily last a guy 5 years. And if some dude were stranded on Mars, SpaceX could start lobbing things in his direction within maybe 30 days?
The Martian is a vision for a 2035 mission from 2011. We seem likely to beat that!
> SpaceX could start lobbing things in his direction within maybe 30 days?
If Earth and Mars are on opposite ends of the sun, nobody is going anywhere within 30 days. I do not see how anything will change from the one transfer window per ~2 years for the foreseeable future
You couldn't start launching things in 30 days, you need to wait for a launch window, which happens every ~2 years. The transit times are on top of that.
While this doesn't apply in the scenario that the person you're responding to has given there are ways to get many more transfer windows between Mars and Earth using Aldrin Cyclers.
> The first mars expeditions will probably be stocked with a thousand tons of gear, enough to easily last a guy 5 years.
> The Martian is a vision for a 2035 mission from 2011. We seem likely to beat that!
What, exactly, is that guy doing for those five years? We don't know how to terraform Mars, and it's questionable what having someone on the surface will add to the knowledge we have of surface composition. And then what? That equipment is still on earth - after it's built.
Oh, and how's he planning to get off Mars?
I would comfortably make a $100 bet that there is no chance that we have sent a manned mission to even orbit Mars by 2035, let alone are "settling" it.
> The effect of this no-abort condition is to make Mars mission design acutely risk-averse.
"Acutely risk-averse" is not SpaceX.
And being acutely risk-averse also underscores my point. If we are actually acutely risk-averse, we aren't going from "still test-flighting and developing the launch vehicle" to "manned mission" in 9.5 years.
> What, exactly, is that guy doing for those five years?
Waiting to be rescued. We're not talking about sending one guy to mars for funsies, we're talking about one person left after an emergency. In the book he gets off mars by going to the launcher staged for the next mission, which again is a case of prepositioning extra hardware before sending someone to the planet.
If you assume a team of 5 people with an intended stay of 6 months, 5 years of supplies is a factor of safety of 2. If you send enough supplies to keep the whole team alive till the next launch window, that would keep a single person alive for about 2 decades (ignoring potential storage lifetimes).
> In the book he gets off mars by going to the launcher staged for the next mission, which again is a case of prepositioning extra hardware before sending someone to the planet.
There's a "world" of difference between the Eagle returning to Apollo 11 in low lunar orbit, and prepositioning a interplanetary vehicle capable of Mars-Earth (after getting from Earth to Mars), landing it (and without live feedback/guidance, because of roundtrip radio time, not to mention, this isn't some Rover, it's a really large rocket) well in advance of the manned mission (8 month flight time, IIRC, which means realistically it's going to be hanging out on Mars for a minimum of 6 years, even if you launch the manned mission within a couple of months of its arrival, which seems ... risky) and hoping that one solo astronaut is going to be capable of fixing any issues that arose during landing or during its ~year, untouched, and five years of his habitation.
Martian dust storms are a thing. "Smaller", continent-sized ones lasting weeks at a time, hit a few times a years. And then you have the planet-covering ones.
> Individual dust particles on Mars are very small and slightly electrostatic, so they stick to the surfaces they contact like Styrofoam packing peanuts.
So many issues. We're not solving these by 2035.
We are still at the point where unmanned, tiny craft with none of these challenges routinely fail. We're making progress, but we're not making that much progress, not that quickly.
Given the results of test 10 (successful splash down of Starship), any ideas what test 11 will entail? Could we be looking at a chopstick catch of the Starship itself?
They're probably gonna keep wasting ships until they've got the exact limits of their capability established.
I know it seems counterintuitive to everyone who grew up in the era of the space shuttle, but the ship is the cheap part, the giant booster is the expensive part.
The ship has a way longer cycle time so starship unit costs are going to dominate fleet construction cost despite being the cheaper unit so knowing exactly how hard you can run them is very valuable information it's worth gleaning by wasting some units early on.
They only have one more shipv2 right now. The next ones are shipv3. So my guess is that a ship catch doesn't make sense, since they're changing the architecture on the next ones. Would make sense to continue with limit finding (it's a disposable launch anyway, old gear) on things that carry over (i.e. thermal protection, ablative materials, crazy angles, etc)
One interesting point is if they actually go for orbit. It would take just a few more seconds to reach something like 200+km / 100km, a place where they could deploy some v3 Starlinks and gather data from the launch (i.e. vibrations, health, dinging on the door, etc). It would be a test where they get more data that's transferable to the new architecture, and relatively low risk of getting stuck in orbit. (low perigee would mean eventual re-entry anyway, hopefully over the ocean) The sats can probably raise themselves from there.
Like you said, flight 11 has the last V2 and since V3 is not compatible with the existing pad A (only the new pad B that is being finished atm), it would be a nice opportunity to try the ship catch because cratering the old pad A and/or its tower wouldn't be that much of a deal. The entire Pad A has to be replaced anyways.
One option is they can run it again with the data gained from missing tiles etc. and see if there is an improvement.
They could also do a similar flight but with an actual orbital insertion and de-orbit if they are confident in the odds of success of the de-orbit burn.
Landing the ship at the launch site means overflying land and potentially populated areas, so I think they're going to want to demonstrate successful control, re-entry, and landing from orbit a few times before attempting that.
But I agree with you, I'd rather have test flight 11 demonstrate at least another successful reentry with no issues (they had a non-fatal explosion on ship reentry in flight 10) before attempting to catch the booster AND landing the ship.
"That was absolutely incredible," SpaceX Build Reliability Engineer Amanda Lee said during live launch commentary. "A huge congrats to all the teams here."
"Great work by the SpaceX team!!!" SpaceX CEO Elon Musk wrote on X after the flight.
Amazing accomplishment. Always a thrill to watch live.
SpaceX conducted 134 launches in 2024 and is targeting a record-breaking 160-170 orbital launches in 2025.
According to wikipedia, the entire cost of the saturn v project was US$185 million, equivalent to US$33.6 billion today. That's from R&D to all launches
You mis-copied the numbers for one launch. Wiki says:
> Project cost US$6.417 billion (equivalent to $33.6 billion in 2023)
> Cost per launch US$185 million (equivalent to $969 million in 2023)
That a manned Apollo mission would/did cost under a billion dollars (todays money) is surprisingly cheap. A single Artemis launch using the Space Launch System (SLS) costs an eye watering $4 billions.
Different metric:
> [1966] NASA received its largest total budget of $4.5 billion, about 0.5 percent of the gross domestic product (GDP) of the United States at that time.
Using that metric NASA yearly budget would with todays GDP be $150 billion dollars.
Some of this was the overall urgency of the 1960s space race, that people were motivated to cut through red tape and get it done, and I know it's also argued that modern safety standards and requirements around supply chain, real time monitoring, system redundancy, etc all complicate things and raise costs.
That said, it would be interesting to have someone really knowledgeable go over what it is that Artemis has and Saturn V didn't, and then break them down and assign each an approximate proportion of the cost delta.
Part of the SLS cost comes from trying to save money. Yearly budgets are kept low, which spreads out the work over a long time. This makes everything cost more, but the politicians only care about the yearly spending.
SLS is also a pretty weird design due to reusing Shuttle components for a completely different kind of launcher. This saves development costs (maybe) by using existing stuff that has already been developed, but the unsuitability of those components for this system increases per-launch costs. Once NASA runs out of old Shuttle engines, manufacturing new ones is going to cost $100 million apiece if not more, and each launch needs four of them. It was OK for Shuttle engines to be expensive since they were supposed to be amortized over hundreds of flights (and in practice were actually amortized across at least tens of flights) but now they’re being used in expendable launches. If Starship even comes remotely close to its goals, an entire launch will cost less than a single SLS engine.
I had understood that reusing shuttle parts was more about keeping congressional districts (that make the parts) happy, and thus securing votes for funding.
No need to be condescending when communication is ambiguous. Your question can be better phrased as, "How much did it cost for Saturn V to reach the point where it could successfully orbit?" which I assume means "how much did it cost up to and including Apollo 4?"
And then we also need to add the costs of the V2, because surely we wouldn't have had Mercury and Gemini without the V2 first... and of course we wouldn't have that if the Chinese hadn't developed the first rockets in the 13th century, so we need to figure out their development costs. Where does it stop?
I think as phrased this is going to get way too pedantic. But I think it raises a larger point which is worthy to consider.
Presumably what we're trying to get at is, in broad strokes, "is Starship more cost-effective to develop than Saturn V" (and I assume the follow-on for that will be to compare the "NASA approach" vs the "SpaceX approach")
But you raise a good point in that the baseline playing field is completely different. The existing knowledge each program started with, be it in materials science, understanding of rocket combustion, heat shield technology, electronics, simulation ability, you name it, it's completely different. So we can find and pull out whatever numbers, but I don't think it's possible for them to say anything meaningful for comparison on their own.
>but I don't think it's possible for them to say anything meaningful for comparison on their own.
It depends on how different they are. Saturn V was launched 13 times in total. Starship is already 75% of the way there and hasn't orbited once. Ignoring R&D and just going by launch costs alone, that's USD 4B (2025) to orbit 1 Saturn V, vs USD x to orbit 1 Starship, where x >= 1B.
Starship has already reached orbit many times but places itself on a suborbital trajectory to intentionally test re-entry and landing which it has done successfully several times.
And is absolutely useless. Apollo 9-17 went to the moon with human occupants. All but one put men on the surface of the moon. They all returned to Earth with zero fatally exploding ships.
Not one of these triumphant 75% achievement in launch numbers would have had a surviving human. Apollo had 0 practice runs. Starship is nothing but practice runs. To equate the number of launches to something so drastically different is just an exercise in futility that I can only assume you're trolling
Dude, when did I say they were triumphant? SpaceX is burning taxpayer money sending empty coke cans on ballistic trajectories for no good reason. My whole point with this line of inquiry has been to point out what a useless waste of resources Starship has been so far.
But who will get to 100 launches first? 1000? Saturn V was in one way a great success that will be remembered for all of history. But in another it was a failure due to your exact statement. It only launched 13 times due to being so expensive as to just not be feasible.
Actually, "let's build a cheaper one and hope it works out" is the design philosophy here, and it's a very effective one across pretty much all domains. The fact that it's bigger too is mostly incidental to its economic case. You think we would have stopped at Apollo 17 if the same Saturn V was capable of flying Apollo 18 - 30?
If we're going down this road, we'd have to include the global GDP back thousands of years. I asked specifically about Saturn V so I could make a reasonable comparison between it and Starship.
Starship isn't exactly the same as Saturn V. It's bigger, for one.
The reason why it matters is that efficiency matters. It's fine if it takes longer, not so much if it costs way, way more, especially if such a huge rocket has limited applications. And as I understand it the consensus is that Starship (or at least a fully-loaded Starship) will never go to the Moon. Once it's in orbit it takes like twenty refueling launches and space rendezvous to fill it up again so it can make the transfer burn. In other words, it's never happening.
I think that understanding of the consensus is incorrect. The mission plan for Artemis 3 is that a specialized Starship upper stage will be refueled in LEO and then transfer to lunar orbit where it will wait for astronauts arriving on SLS/Orion.
Yes the mission profile is more complex, but that complexity can mostly be settled before the astronauts launch on their mission.
NASA seems to think it is a viable plan which is why they selected SpaceX to execute that part of the mission.
> After a multi-phase design effort, on April 16, 2021, NASA selected SpaceX to develop Starship HLS and deliver it to near-rectilinear halo orbit (NRHO) prior to arrival of the crew for use on the Artemis III mission. The delivery requires that Starship HLS be refueled in Earth orbit before boosting to the NRHO, and this refueling requires a pre-positioned propellant depot in Earth orbit that is filled by multiple (at least 14) tanker flights.
I stand by what I said: not happening. I'll believe it when I see it.
Can you imagine if to make a sightseeing trip to another city you had to stop in the middle of the highway and then make 14 round-trips with a second car to fill your first car back up? I can't imagine why someone would approve this plan, other than corruption.
> Can you imagine if to make a sightseeing trip to another city you had to stop in the middle of the highway and then make 14 round-trips with a second car to fill your first car back up?
If the alternative was throwing away and building/buying a new car for every trip? Absolutely.
They said the same about landing a first stage booster - impossible and pointless to attempt. And it just happened for the 400th time yesterday.
False dichotomy - the mission profile dictates the refuelling station and all that, but it never was the only option. Somehow we've decided we needed to be able to do lots of trips to the moon for Artemis, but it's not clear to me that it's such a precious golden oportunity and warrants this spending/impact on the environnenent.
We didn't get to the moon with a refuelling station did we? How come we need one now? We're really seeing 15 starship launches per moon trip as reasonable, rather than just building a single trip program?
The mission itself is nonsensical. The problems are stemming from the SLS, I'll find a link to a relevant source.
> We didn't get to the moon with a refuelling station did we?
No. We did it by throwing away ~98% of the vehicle on the way there.
> How come we need one now?
Because building a new gargantuan tower and tossing that majority of it into the ocean/deep space every time we need to go the moon is not sustainable.
> We're really seeing 15 starship launches per moon trip as reasonable, rather than just building a single trip program
Yes. Because again. The alternative (dictated by physics) is that we expend the whole thing.
The Apollo missions landed two crew members in a tin can with extreme limits on what weight they could bring with them in either direction.
A single trip launch will always be constrained like this due to the tyranny of the rocket equation.
A modular mission system with multiple launches is the best way to expand capabilities and enable things like landing larger payloads for more advanced or long-term missions.
IIRC, the expected return payload for this is lighter than Apollo. In no small part because they're dropping all their return fuel and their entire return vehicle into the Moon's gravity well, rather than leaving it in orbit. Subjecting themselves to extra abuse from the good ol' rocket equation.
The vehicle that returns to Earth is Orion which stays in NRHO and does not bring its fuel to the lunar surface.
Return payload constraints are probably from using Orion as the return vehicle. Mass to the surface is much higher than Apollo since that is launched separate from the crew.
I thought the return vehicle was a to-be-developed direct-return vehicle from both SpaceX and Blue Origin (both got contracts, and supposedly both's versions will fly)?
[EDIT] Apparently there are multiple plans involving even more spacecraft, because why not I guess? It's as you describe for Artemis III, but then gets way more complicated with Artemis IV, involving more spacecraft for some reason.
As far as I know all of the known Artemis mission profiles only use the lunar lander to shuttle from NRHO (lunar orbit / gateway station location) to the lunar surface and back. All crew return is planned to be done with Orion for now.
NASA has optioned an additional lander from Blue Origin but that would be taking the same role as SpaceX's lander, shuttling from lunar orbit to the surface and back to lunar orbit.
There's never going to be long-term crewed missions to the Moon. It has no scientific value. Even the little exploration we did in the '60s and '70s were a dubious proposition. There's not that much we could do by sending people that we couldn't do by sending robots.
If you think there's no value to returning to the moon, building a base, etc. then fine. But you keep moving the goalposts of what you are taking issue with here.
And yet the boosters are not being reused. They're just making brand new engines for every launch. If we're generous they're being dismantled and recycled.
Alright, if we're talking about Falcon 9, I don't know what the cost savings are for a reusable rocket, or if there are any. If someone has that data, feel free to provide it.
> As of 2024, SpaceX's internal costs for a Falcon 9 launch are estimated between $15 million[186] and $28 million,[185] factoring in workforce expenses, refurbishment, assembly, operations, and facility depreciation.[187] These efficiencies are primarily due to the reuse of first-stage boosters and payload fairings.[188] The second stage, which is not reused, is believed to be the largest expense per launch, with the company's COO stating that each costs $12 million to produce.[189]
The mission is wildly more complicated than the Apollo missions. There's a whole oddball-orbit space station that has to be placed as a way-station, for one thing, and none of that's happened yet (remember how long it took to build the ISS?). Also, landing all your return fuel instead of leaving it in orbit, so a way heavier lander (with a smaller return payload than Apollo!), which is a pain in the ass. Multiple space ships launched by different rocket systems involved. The SLS still has to be finished for it to go forward. Orbital refueling of large fuel tanks is a hard problem that remains unsolved, and this goes nowhere without fixing that. The contracts for the return vehicles are disturbingly light on parts about making sure they can reliably work, including surviving re-entry.
I'm with you. Not happening. We're more likely to come up with a totally different, simpler plan, and do that instead, before this happens.
You can easily mathematically prove that orbital refueling increases mission efficiency. This is a simple fact, it's not about Starship or whatever. Your analogy does not hold.
"It's fine if it takes longer, not so much if it costs way, way more, especially if such a huge rocket has limited applications."
Taking longer at lower cost is a great trade-off for Starship but wasn't for Saturn V. The main driver for Saturn V was the space race against the Soviet Union. Economic interests played a very small role. It was all about being first and compensating for the Sputnik shock.
Adding to previous comment, looks like the cost per launch when the system was up and running was ~1billion USD inflation adjusted. I'm going to assume Starship will beat that easily.
Maybe, but remember that getting astronauts to the moon and back took a single Saturn V launch but with Starship, it will take (at least) 10 flights for refueling, possibly as many as 20. So each launch has to be much cheaper to beat Saturn V for the full mission.
Nobody but SpaceX knows how much each Starship test costs but the estimates online range from $50 million to $200 million. Presumably, whatever the actual cost, they're more expensive right now while they're redesigning bits and doing custom, one-off work for each flight but it has a long way to go to beat Saturn V for the full mission.
A starship mission to the moon will land over 100tons of cargo. Saturn V could get roughly 5tons to the surface. Its an entirely different class of operation.
That's LEO, not to lunar orbit and entry. Saturn V had a maximum lift capacity of 310,000 lb (140,000 kg) to low Earth orbit (LEO) and could deliver approximately 50 tons (45,000 kg) of payload to the Moon.
Looks like Starship test flights are already beating that $1 billion per-launch cost (I'm seeing estimates in the $100-500 million range), and they'd like to get the marginal cost down to ~$10 million.
There were no Saturn V test flights like Starship is doing, that I can find info on. Wikipedia lists 3 tests before Apollo 4, which was the first full launch.
From context I interpreted GP to be somehow concluding that Starship is "cheaper" (these test flights are "beating" the price tag of the Saturn V launches), I'm gently pointing out I don't think that is a reasonable conclusion to draw based on empty suborbital test flights vs. taking humans to the moon and back
It would seem no one has the information I originally requested. All we have to go on for Saturn V is a per-launch cost where we don't know what's included. I agree it's an apples-to-oranges comparison, but it seems to be all we have.
You can't really compare them because SLS was a jobs program intended to spread out contracts across many states by reusing suppliers from shuttle programs. Cheap? No. Wasteful? also no. Most of that money went back into those economies.
That's not how it works. If you pay people to dig a giant hole in the ground and then fill it back in, that money "goes back into the economy" but that doesn't mean it's not wasteful.
Ahh, much like the economy has grown so much because the government gave people money and shovel to dig and refill holes. Went back into the economy, must've been a good move. Let's not bother considering what else could've been done with the money.
> Wasteful? also no. Most of that money went back into those economies.
If the government 100B to dig a big hole and fill it up again, that money would also "go back into those economies". Does that mean it wouldn't be wasteful?
The money could have gone into those economies while also securing a productive accomplishment (or more productive accomplishments depending on your opinion of SLS). Factories could have been retooled and workers could have been retrained to produce things of greater value instead of deliberately keeping them obsolete. It's still wasteful even if not completely useless.
It's a very cool rocket and this success is a nice change of pace from the past several failures. However, I just have to say:
> Mars rocket
Very dubious. If you disregard all the SpaceX marketting talk and just go by what they're building, then it's a rocket meant for launching very large satellite constellations as cheap as possible.
The only reason they're doing full reusability is to enable Mars missions. Had they only wanted cheap flights for satellite constellations they could have launched with what they have now (i.e. reusable booster and single use starship), and it would be cheaper than anything on the market with huge upmass capabilities.
Something that I rarely see mentioned about SpaceX's goals and financial viability of a reusable Starship is how significant of a boost they get to their talent pool by working on the absolute bleeding edge on things that seem impossible. People go work at SpaceX because they work on crazy things like Starship instead of only working to make "cheap flights for satellite missions". SpaceX attracts the absolute cream of the crop (at below market rates even but that's besides the point) and those people work better/harder than they ever would working on more boring goals. It's the power of vision and motivation.
The constellations they can launch now are only a small fraction of the size they aspire to launch. Their plans for Starlink alone call for almost 10x as many satellites as they currently have. Then there are all the other constellations they might launch in addition to Starlink, including defense contracts that might call for rapid replenishment of expended/destroyed satellites.
As for Mars, Starship might be ready for that in a few years (a year ago I was saying in a year or two, but I've kicked that back). But where are the Mars customers? Who is developing Mars habitation plans and hardware that will be ready in even twenty years? Commercial demand for large satellite constellations obviously exists. Demand for Mars colonization is nonexistent, it exists only in the hopes and dreams of sci-fi junkies.
I really hope I'm wrong, because I'm a sci-fi junkie!
Incredible achievement, but what is more incredible is how many people (including almost all of my friends circle) have started rooting for SpaceX to fail due to the shenanigans of its founder.
I think as a culture we've lost the ability to compartmentalize. We should be able to criticize and even despise the head of a company, and at the same time celebrate when the intelligence and hard work of the countless smart and hard-working people at that company push the boundaries of what is possible for humanity.
If the king managed to build their palace in the clouds? Yes. That’s a pretty awesome achievement. Not the kings’s achievement, but the achievement stands.
I am rooting for them all. I don't need to like the founder, or his politics. I understand that Gwynne Shotwell and so many others are behind much of the progress.
Shenanigans of its founder being falsely accused of doing a Nazi salute when he was just waiving and not agreeing with certain peoples politics. When someone tries to compare someone to the most evil person that has ever existed then odds are that person is lying through their teeth. On one had we have a 'wave,' literally, and on the other hand we have genocide. It's incredible to me how many people choose not to see through the lies about Elon Musk, even though they have the capability, and to this day think he is a nazi.
I mostly hope that Blue Origin will be a worthy competitor.
For me what this shows that the most important thing for a CEO to be successful is to have money, a vison (no matter how unrealistic or unnecessary) and a cult personality. Nothing else matters. Also it shows that with enough virtual money (I.e.: massively overblown Tesla stock) you can do just about anything.
Fun trivia fact of the day: BO was founded 2 years _before_ SpaceX. 25 years later, SpaceX has revolutionized the launch industry. Meanwhile, BO has only just had their first (and only) orbital launch at the beginning of this year. It's unclear to me what, if anything BO could do to really catch up at this point.
It's clear that money isn't the defining factor at least. When BO was founded Bezos was the richest man in the world. It has floundered for so long that Musk was able to build up a cult of personality around SpaceX and parlay that into even more money than Bezos.
They each have different failings. Elon is taking an absolutely bullshit approach to project management: if Starship can't meet payload specs, it can't refuel in orbit. Neither of those monumentally risky milestones are even close to being attempted.
Jeff loves measurement and control. So he replaced his experienced aerospace guy with the Alexa guy. Because the Alexa guy works the Amazon way: everything measured and tightly controlled.
Blue Origin was founded before SpaceX, and Jeff Bezos had way more money back then. And when Elon Musk founded SpaceX few people had heard of him and he wasn't even a billionaire. Tesla didn't exist yet, so there was no "massively overblown stock." And where is the "unrealistic vision?" Looks like it turned out to be pretty realistic to me.
Musk has a self-destructive streak where his ambition exceeds his understanding. Examples are over-automation of Tesla Model 3 production, autonomous vehicles without Lidar, and the Cybertruck.
Will Starship every carry a large enough payload to justify the launch cost? I'm skeptical. Musk's Mars fixation is nuts.
You're significantly downplaying the damage done. We can compartmentalize someone having an affair, but election of Trump, support of AfD, and DOGE activity are beyond the pale.
Supporting DOGE is an extremely intelligent thing to do with the amount of debt our government has, 34 TRILLION last time I checked. Supporting a democratically electable party, and eventually the elected president of your choice is the right and moral thing to do by all objective measures, including if you believe in majority rule. Politics is always about disagreement and every generation thinks their disagreements are the most dire, but in reality live moves on. By siding with the literal winning party you are defacto 'moral' in the eyes of the majority.
Did you ever make the effort to ask why he did those things? There’s a possibility that the person who aimed high for team humanity with SpaceX, Tesla and Neuralink was doing exactly the same thing in the examples you named.
This is something I am finding myself wrestling with a lot right now.
On the one hand I am a major space nerd and I see the value of what SpaceX is doing. Especially with it really seeming like no one is anywhere near their level. What kind of scientific advancements will be possible once this thing can be used normally and launches like this become commonplace.
But at the same time it is impossible to ignore the Elon situation. And that also directly relates to Trump as well. We are in this bonkers situation where he helped get a largely anti-science administration in power and yet also runs one of the companies that will help science.
It does raise serious questions about whether or not there will be limitations on what types of science can be done. Will they have some line in the sand and say they won't launch satellites that do "X", like maybe monitor climate change.
I think maybe rooting for them to fail is a bit much, but I am sure as hell hoping that someone else can catch up. But in the mean time I will celebrate these achievements cautiously. Recognizing the amazing work that the engineers at SpaceX have put into this, because they do deserve a lot of credit for that.
What if the guy who built the world’s best rocket from scratch, who popularized EVs and brought self-driving tech to the masses, who built brain computer interfaces, dug tunnels, started OpenAI and PayPal…
What if he’s not an idiot?
What if we should actually be listening to what this guy says and considering it?
What if he has the same ability to see what nobody else can see early on in politics…
You don't look for smart people by looking for people who don't do dumb things. Everybody does dumb things. You look for people who have done smart things. Idiots don't do smart things.
"Dug tunnels" - one of the most ridiculous boondoggles of any modern industrialist. The Boring Company is a machine for overpromising to get government contracts and underdelivering at exponential scale. He didn't start PayPal, he joined it and ended up getting fired, albeit with a golden parachute that gave him the chance to make more bets.
The "accomplishments" you're listing are mostly just investments that he managed to hype up very well. I'll give him this, he's an excellent huckster. But listen to his opinions? I wouldn't let him tell me what color an orange was.
- Deletion of public health information and historical weather databases.
- Criticism of vaccine effectivness
- Defunding of health and climate research funds.
- Leaving the largest international research alliances in Climate and Health.
- Defunding of NASA
He called the administration anti-science, which is well grounded claim. But no part of the phrasing implies that "republicans" are anti science or that you are.
It’s honestly amazing what SpaceX has been able to accomplish despite Elon. I mean - look at what his interference has done to Tesla and Twitter. The execs at SpaceX seem like they know how to manage Elon so that their employees are actually able to deliver.
I am stating an example due to the current political discourse over climate change not that it would be something they specifically would not do.
My point with stating it, is it is not unreasonable to ask the question if we are reliant on a company with someone like Elon owning it is what the company will and will not fly going to be dependent on politics.
Are you trying to say that trans men don't exist and somehow lack the ability to get pregnant?
That is pretty basic to proove. Do they identify as male after transitioning? Yes. Do they have a Uterus? Yes. You have a male that can get pregnant (yes I am over simplifying here but whatever)
Now if you wanted to say, a cis male cannot get pregnant. That would be true and no one is attempting to argue otherwise.
Maybe. But also as the founder and largest shareholder is someone willing to funnel money in to far-right causes across Europe, it's really hard to root for the company as a whole.
Advancing human scientific progress, but at what cost?
>The parties opposed to child rape and unreasonable levels of immigration in Europe get called far right because they do scoop up a few far right supporters.
Flagging your comment as well because AFD is definitely not a "few far right supporters".
The issue isn't being against child rape and unreasonable levels of immigration. The issue is that the people who are against that are all liars and charlatans, just like in United States, where the party of moral righteousness and small government is full of child molesters and currently doing some pretty authoritarian shit.
Just because a problem isn't getting addressed as fast as one hopes doesn't mean that one should completely jump ship to literally anyone who offers support for your cause.
At a cost of indiscriminately imprisoning and killing people (remember Korolyov and von Braun)? Surely. he-he.
If Musk does achieve a second foothold for the humanity, then any and all objections to his methods become irrelevant. So far he does deliver. So we wait for the final result.
Also, if you don't know, we've got a war in europe for like 3.5 years already.
I'm seriously curious how many times a space-x total program cost since their start in 2000s has been already sunk into that.
Im rooting for Space X to fail partly because Starship is such a fantastically dumb idea, which isn't a surprise given the mental decline of Musk over the years.
To have it go to Mars, you have to have something like 20 refueling launches.
Raptor engines are the equivalent of taking a 2.0 inline 4 engine in a car and making it produce 1000 hp. Demonstrating one restart does nothing. You have to demonstrate reliable restart in a variety of conditions.
Vertical landings using engines to slow is inneficient. Sure, you reduce system complexity in not having wings or parachutes, but you gain it all back with things like engine restarts, and the need for high pressure ratio engines.
>I think as a culture we've lost the ability to compartmentalize
There is a limit to how bad a person can get, after which its probably worth for anything adjacent to him to fail so that he can't do the things he does. If Musk was aligned behind someone like George Bush, he would receive a fraction of the hate he does now. But at this point with Doge and his rallying behind a dictator (only to be hilariously dumped and fucked over with the BBB) is bad enough for all hate towards Space X to be justified. We would be better of as a society if people had more of a moral compass and actually did things like quit companies. Its not like there isn't competition with much more sane people at the wheel for Space X and Tesla.
So he's generally an ass to work for, got behind a politician you don't like, and fired a bunch of bureaucrats that probably shouldn't have been fired? Is that it? GWB started a completely unnecessary war, so if that's your example of OK in comparison, then I struggle to understand your standards.
> Vertical landings using engines to slow is inneficient. Sure, you reduce system complexity in not having wings or parachutes, but you gain it all back with things like engine restarts, and the need for high pressure ratio engines.
Well, the most cost effective rocket ever built uses this, but please do elaborate. What system do you propose that would be better?
I was thinkin more along the lines of unconstitutionally cutting things like USAID thats going to actively result in more unnecessary deaths, personal vendetta against LBGT organizations in cutting those budgets, cutting IRS funding which is going to end up costing more ironically as there isn't enough staffing to pursue all the people using tax avoidance
Not to mention in general supporting someone and donating campaign funds who literally tried to coup the government, contributing to him being elected, and thus being responsible for everything that Trump is doing, from fucking up the economy further to playing wanna be dictator with ICE, all of which have long term repercussions.
In comparison to GWB, Trump is going much worse (especially if you want to compare deficit spending), and Musk has a direct hand in that.
>Well, the most cost effective rocket ever built uses this, but please do elaborate.
Cost effectiveness has nothing to do with engineering. For example, I can start a car company, fund it with my other business venture, and then sell cars for $50 and it would be the most cost effective car.
> cutting things like USAID thats going to actively result in more unnecessary deaths
That's bad IMO, but not helping people isn't remotely the same as starting a war that kills them (different if they were US citizens, but in this case they aren't).
> personal vendetta against LBGT organizations in cutting those budgets
I don't even have anything against these organizations, but I would cut their budgets to zero if I were in charge because funding them is none of the government's business.
> cutting IRS funding which is going to end up costing more ironically as there isn't enough staffing to pursue all the people using tax avoidance
This is dumb, but hardly a moral issue.
> In comparison to GWB, Trump is going much worse (especially if you want to compare deficit spending)
I 100% agree, but so was Biden, and I don't blame everyone who supported him either.
Fundamentally I don't blame Elon (or anyone else) for anything that Trump (or whoever they supported) has done that he didn't have a direct hand in e.g. DOGE. It's the nature of politics that you have to swallow a lot of things you don't like when you choose a side to support.
Look bro, we can spend arguing about details, but in reality, its pretty easy to put a nail in this: Trump tried to coup the government in 2020. And Elon supported this. This is not arguable. There is no fake media around this, you can read the lawsuit that resulted in the Supreme Court immunity ruling yourself.
You would have to prove with exceptional evidence that whatever Biden did or Kamala would have done would have been much worse.
Literally no other issue matters until you get over this bridge. Unless of course you are in support of a dictator and think his attempt to throw any legal process and the constitution out was justified, but at that point just say that instead of dancing around the issue.
>It's the nature of politics
No, at this point its solely in the moral/fabric of society territory.
I'm sure there could be better rocket configurations than Starship - but so far Starship is better than other existing schemas. Starship is really good comparing to others - getting the cheapest kilogram to orbit cost in perspective.
[Even worse than someone ranting like this is someone who then on top also self-replies!]
"But explosions aren't THAT bad"!!
Yeah, it just means that up until now, the chance of any astronaut crew surviving any trip anywhere is 0%. But hey, if some of the next tests don't end in an explosion, this maybe can be improved to 50/50 chance of death. Yeah, astronauts will buy that. After all, people also still buy Telsa's "Full Self Killing".

Uh, this is very unfair to SpaceX as a whole, which has had 0 fatalities so far on the ground and in the sky, after almost quarter of century of operation. This is a remarkably good record for spaceflight.
Contrast it to the Apollo project, which killed three astronauts even before the first flight (Grissom, White and Chaffee burnt to death during testing on land) and almost killed another three during mission 13.
Contrast it to the space shuttle with its 14 victims, and the first flight of the space shuttle was touch and go as well.
Contrast it to Boeing whose recent Starliner proved so problematic that they did not dare fly the astronauts back to Earth using the same ship and made them wait for a Dragon.
Contrast it to Scaled Composites, which never reached orbit, but three engineers were killed on the ground and one test pilot during a suborbital test flight.
Insinuating that SpaceX is a killing machine is absurd, when you look at their actual safety record and compare it to their competitors.
Too many things don't add up, for example: SpaceX, and friendly commentators, have framed this as a highly experimental test flight. The most visible aspect of that are the heatshield test tiles on various parts of the upper stage.
That kind of testing is understandable to a certain extent. But it doesn't make sense to ditch the rocket in the Indian Ocean once you've run those experiments, instead of catching it, and having all the parts available to study.
I don’t think they are letting go of these rockets; they are definitely being retrieved back. Otherwise, rival countries like China will end up retrieving them.
Starship is like AI/LLMs in that success would revolutionize the world, but technological failure is very possible. And despite the confident predictions on the internets, we don't know which it's going to be.
After the Shuttle program ended in failure, work on reusable launch systems stopped for decades. A similar thing would happen if Starship fails. Space would remain the province of the military and large governments.
Today it costs ~$3,000 per kilogram to put something in orbit (on a SpaceX Falcon 9). Starship aims to lower that to $10 per kg. That's totally crazy, but even if it could get it down to $300 per kg, that would revolutionize access to space.
Data centers in space, biotech manufacturing, and maybe even asteroid mining and energy generation become practical at those prices. To say nothing of telecommunications, remote sensing, and global navigation--all become much cheaper.
And, of course, that drops the price on all the cool science/exploration goals that we always talk about: massive space telescopes, regular probes to all the planets, and crewed exploration.
We're literally at an inflexion point between two possible futures and we don't know which it's going to be. If I were younger I would absolutely try to work at SpaceX to help tilt the chances.
But as it is, all I can do is root for them.
> After the Shuttle program ended in failure, work on reusable launch systems stopped for decades. A similar thing would happen if Starship fails. Space would remain the province of the military and large governments.
I really don't agree with this take.
It may appear as if SpaceX is the only game in town, but in reality a lot of this technology is commoditized now, and space is as diversified and vibrant as ever.
The starting point today is very different from the post-Shuttle environment. If Starship fails, it is unlikely to be for pure technology reasons and something else will take its place with perhaps better product-market fit.
SpaceX is a symptom, not the cause.
The true dangers to all of these lofty human enterprises are geopolitics, domestic political destabilization and environmental collapse.
I would actually argue that Apollo and the space race damaged reusable launcher projects more than the Space Shuttle. Before the mad scramble to the Moon there were many interesting infrastructure projects and incremental manned mission planned as well as partially or fully reusable launcher or variants of existing expendable launchers.
Then everything that was not contributing to MOON ASAP was thrown away & massive spending on space hardware essentially normalized. The end result (Apollo) was impressive and achieved the goal (first on the Moon) - but was also totally unsustainable, resulting in a big crunch and a lot of setbacks and slowdowns.
Another contributing factor has been military involvement - again, wee need that milsat on orbit and we need it now, costs be damned. ICBMs not being exactly reusable does not help. Even the Space Shuttle design being perverted into its partially reusable clunky form can be traced back to military requirements.
Great point! There were many reusable projects in that era, but Apollo budgets consumed everything else.
I still think Shuttle could have worked, if it had been cheaper to evolve it.
Elon's focus on Starship is to make each iteration as cheap as possible, which means they can radically evolve the design without fear. Think of the (recent) switch to hot-staging or the evolution of Raptor.
If Shuttle had been able to evolve like that, I think they could have gotten the cost down. If you think about it, Starship is basically just Shuttle with the orbiter stacked on top of the booster and with propulsive landing.
> I still think Shuttle could have worked, if it had been cheaper to evolve it.
I doubt it. It's a gigantic kludge that isn't fixable.
For example, the requirement that it land like an airplane meant it needed wings, landing gear, and a full set of flight control surfaces. None of that is useful apart from the landing, and yet it is necessary to push it all into space and re-enter it.
I once emailed Homer Hickam about it, and he was kind enough to reply and said he'd argued the same thing.
The shuttle is the only rocket system that put part of the rocket above the payload. Were it not for that fatal design flaw, both fatal flights would have been survivable. The first because the explosion would have done less damage. The second because there would have been nothing above the shuttle from which something could have fallen.
I think @WalterBright is probably right and that the Shuttle design was too compromised to be fixable.
Stacking the orbiter on top of the external tank is a non-starter, IMHO. Obviously you'd have to add engines at the bottom, but now your cost goes up unless you plan on recovering the external tank (and how do you do that?).
And now you need another fuel tank for the orbiter, right? Do you extend the orbiter so it can fit an internal fuel tank? Or do you remove the engines and move them to a separate disposable stage?
The Shuttle cannot even fly straight. The engine thrust has to be tilted.
Ouch! These arguments are new to me, and so painfully obvious from an aircraft design point of view. Ouch!
None of that would have been a serious concern had the shuttle actually met any of it's re-usability claims. It doesn't matter that it costs a bit more in fuel and initial outlay for the orbiter if you actually could turn it around with little effort or cost in a couple weeks.
Having to inspect each and every tile after every trip because they basically didn't work like initially designed was the primary failure of the Shuttle program. It also wasn't nearly safe enough, primarily due to a shitty management culture that was taking over America (and is still currently in power in nearly every business).
The thermal tile technology was for some reason believed to be dramatically easier to design, engineer, and manage than it ever came to be in reality. I'm not convinced that Starship has "solved" the problems inherent in tile systems.
That assessment massively underestimates the impact of all that machinery needed to fly it, in terms of design, cost, maintenance, etc. It cannot be wished away.
Fair enough!
That's sort of a fallacious argument though because you could say the same thing about every part of a spacecraft that is used only for the return phase of its mission.
It might be more accurate to say that the ratio of mass for re-entry equipment to the entire craft mass is too great.
But with that said I think that the ultimate failure of the shuttle was that the design wasn't amenable to low cost maintenance. A spacecraft could have a crappy payload to orbit as long as it's cheap to maintain and use with quick turnaround.
I have a feeling that should Starship succeed this will be the case with it and it will end up having a substantially lower payload than intended but will make up for it with a design that's cheap to build and maintain.
It's not fallacious at all. Look at the difference in the hardware bringing the Apollo crews back vs Shuttle crews. Several orders of magnitude.
And what's the ratio of that to the returned payload mass?
I disagree. If Starship fails, the most likely reason will be technological. Either they can never get the heat shield to be reliable, or they can't get cost down below Falcon 9 (meaning, refurbishment costs are too high).
And if it fails, who will spend billions on a new vehicle?
Stoke Space: They are working on Nova, which is designed for 2nd-stage re-use, and they've got a novel architecture. But they are not well-funded and if Starship fails, it is likely that investor sentiment will shift away from full reusability (you know how investors are). And even if they succeed, their current vehicle can only get 3 tons to orbit. That means each launch must cost less than $1 million to get to the $300/kg target. In contrast, Starship can loft 100 tons, so it can cost up to $30 million per launch and still hit the target.
Blue Origin: They are still working on 1st stage re-use, and even assuming they get that to work next year, they are at least a decade away from testing 2nd stage re-use. And their current designs don't have any of the cost-savings in Starship (like launch-tower catch).
And that's it! There are no other companies seriously working on 2nd-stage reuse.
If Starship fails, there will not be another contender for cheap flights to orbit for decades.
> Either they can never get the heat shield to be reliable, or they can't get cost down below Falcon 9 (meaning, refurbishment costs are too high).
There are a lot of other potential technological problems (dozens of engines, stainless steel construction, the belly flop maneuver, etc). Ultimately if Starship would were to fail for technical reasons, it would only indicate the particulars of Starship's implementation don't work. Starship is not the only (or even in my opinion the best) way to achieve full reusability. And partial reusability, which just a few years ago was considered radical, has already been so firmly proven that just about everyone is doing, or trying to do it. The idea of "don't destroy this extremely expensive vehicle after only a single use" won't die for as long as people can see expenses on their books.
If anything, the alternative approach, making a low cost, mass producible rocket has been abandoned, possibly pre-maturely.
Rocket Lab tried the alternative: low-cost, mass-produced expendable rockets, and Peter Beck famously ate his hat when they pivoted to reusable.
Partial reusability won't get the cost down to the ~$100/kg range. And it definitely won't do that and still loft ~100 tons to orbit.
Falcon 9 can get 15 tons to LEO for $45 million, and that's already the lowest price on the market. To hit $300/kg they would need to build a 2nd-stage, launch, recover (on a drone-ship) and refurbish for $4.5 million. That's just not going to happen.
There are only two companies that are actively building hardware for 2nd-stage reusability: Blue Origin (which doesn't even have a prototype yet) and Stoke (which has a max 3-ton payload). If Starship fails, we are not getting $300/kg orbital costs for 1-2 decades minimum.
I agree that Starship has lots of other potential technological blockers (although fewer each attempt--I never thought tower-catch would work the first time). But no other designs are even close to fulfilling the promise of low-cost orbital launch.
AFAIK there is a bunch of Chinese startups pitching some fully reusable designs and/or ready to clone something that works. There is already some Falcon 9 like first stage reusable booster prototypes in development.
Maybe. There are a few trying 1st-stage reuse. I don't know of anyone actually working on 2nd-stage (beyond concept stage).
The thing is, there is no demand to get that much stuff into space.
Falcon 9 has massively brought down the cost per orbit, and even with the whole world as a captive market, every university in every country putting up cubesats, they still don't have nearly enough payloads to make the economies of scale kick in. Hence Starlink. The majority of SpaceX payload mass has been Starlink, something nobody was even asking for. 300+ launches.
And the idea to reach the economies of scale for Starship is... Even more Starlink. How much Starlink could we possibly need? When will humanity come up with another use for this glut of payload capacity?
Even with the Artemis deadline looming large, SpaceX are still pushing this Starlink angle for Starship, it's nuts
Demand takes some time to ramp up, especially with quite expensive and complex stuff like Satellites. SpaceX is now even launching competing constellation comsats (project Kuiper), private manned space missions and there are quite a few manned space station projects under development that would be basically unthinkable without the cheaper lift Falcon 9 provides.
As for "How much Starlink could we possibly need?" I think the answer is simply "YES". Even when you possibly somehow satisfy all your Internet access customers, you can start adding other services, like mobile phone coms (already in progress) or maybe imaging or hosted payloads.
Agreed!
Even at $300/kg to LEO there are a ton of new applications that suddenly make sense. If we get to $10/kg we will literally colonize the solar system.
Yeah - while real space development will use 99% of local resources eventually, the cheaper we can get stuff to LEO the quicker we can get things going. Not to mention lifting any complex stuff & humans, that which simply not be available otherwise until much more stuff is operational in space.
Haven't the economies of scale already kicked in a little? Starlink is profitable. I'm not sure if spacex minus all starship costs is profitable. I'm pretty sure they're quite good at building them faster, better, and for less now. Please show me otherwise. I guess you could call that more learning curve, but that's a fuzzy line.
I guess overall I don't understand your point. What does it matter that the majority of their payload mass was their own? And nobody asking for something is certainly not the same thing as nobody wanting/needing it. See: cars, computers... Starlink now exists and I'm quite certain people love it and rely on it. Wouldn't exist without falcon 9. Starlink basically solved the last mile problem, surely you'd agree rural folks having access to Internet is a good thing?
They made their own demand for falcon 9, with that scale bringing down costs enough to raise demand for basically every research org needing satellites to contract with SpaceX.
I don't think we can definitively predict the demand either way for payload at $300/kg or whatever without first getting there, but Jevons might have some ideas.
Demand comes at a curve, the cheaper you make it, the more demand there will be. The demand for satellites and eventually human travel is practically infinite if the cost is low enough.
If Starship cuts cost to orbit by at minimum 1/3 and at maximum 1/100th demand will skyrocket (pun intended) either way.
Starlink is both a successful commercial service making money hand over fist and a vital strategic asset for the United States. Put simply its one of the most transformative infrastructure projects of the 21st century. SpaceX found a winner and is doubling down on it I don't blame them.
"Space would remain the province of the military and large governments."
Falcon 9 launches are already only ~10% government payloads, ~90% commercial payloads. They're already vastly not military/government launches.
Sure, not directly. But most of that is imaging and communications payloads, and the vast majority there is being purchased by militaries and intelligence agencies.
Government still props up this whole market.
Fair point!
I should have said that the space economy would remain small.
With the ability to lift more weight, it also means that the travel time to Mars could be shortened considerably (by using more propellant).
The minimum propellant travel times are a major barrier.
> After the Shuttle program ended in failure, work on reusable launch systems stopped for decades
Did it really stop for decades? I think SpaceX and Blue Origin were both already working on re-usable launch systems around that time
After the Challenger disaster (1986) it was clear that the Space Shuttle was never going to accomplish its cost and reliability goals. The US military had bet everything on the Shuttle, so it needed a new launch vehicle. The one clear requirement of the new launch vehicle was that it had to be expendable. In fact, the name of the program was "Evolved Expendable Launch Vehicle"[1]
Remember also that when SpaceX started to develop Falcon booster reuse in 2011, every major aerospace company said that reusable vehicles would never make economic sense. Even after the first Falcon 9 recovery and re-flight, most aerospace companies thought reusability was a dead-end and that belief came from the refurbishment cost that Shuttle had to go through.
I count from 1994 (start of EELV) to 2021, when NASA launched astronauts on a reused booster and Peter Beck famously fulfilled his promise to eat his hat if Rocket Lab ever worked on a re-usable launch vehicle.

SpaceX started with the business plan of low cost, mass producible single use launchers. Falcon 9 was not designed with any level of reusability in mind. There was a major redesign to add landing hardware, but the whole reason for Starship being a totally new design was the reusability that a Falcon "super-heavy" derivative could never achieve.
Good point! I don't think Falcon 9 is large enough for full reusability.
I don't think Stoke's first vehicle will be large enough either (beyond proving out the technology). They will eventually need to build a much larger one.
Assuming it doesn't trigger Kessler Syndrome.
With one company being so far ahead is actually a good thing: No tragedy of the Commons. Or reckless gambling on unproven technology.
Agreed!
Also, Kessler Syndrome is over-feared, like the China Syndrome from the nuclear age.
At Starlink orbits, space debris renters in years, if not months. And even then, having cheap access to orbit would allow us deploy replacements quickly.
At GEO, the distances are so vast that Kessler Syndrome is much less likely (though not impossible).
In between, there is some danger, but again, cheap access to orbit gives us the possibility of clean up.
Well, SpaceX originally wanted 1000km+ orbits for Starlink, which would basically never have decayed.
Said fear was relevant.
Why do people talk about data centers in space? Heat management is wayyy harder in space.
Simple: VC money. The only thing surprising to me about that is that the pitch wasn't "AI in space".
My take: The idea that heavy computing in LEO is better than sending data down to Earth sounds very naive. Starlink is great proof that the bandwidth is plentiful and the latency is good, once the equipment is modern. Definitely cheaper and easier than cooling a datacenter.
> The only thing surprising to me about that is that the pitch wasn't "AI in space".
"enabling the future of AI by deploying the largest training clusters on data centers in space."
https://www.starcloud.com/
Lots of things are harder in space; maybe even everything. But it has some benefits, like abundant solar power, lots of room, and line-of-sight to large chunks of Earth.
Almost all the problems can be solved by cheaper access to space, whereas the benefits cannot be easily recreated on Earth.
Is it guaranteed to work? My point is that we don't know, despite confident assertions one way or the other. If it does work, the benefits are clear, and that's why it's worth trying.
Common folk assume that the space is super-cold, so it must be good for hot servers.
I don't know about common folk, but I've heard about radiators, which can be as large as you want if you can get mass to orbit cheaply.
Sure, but also much less efficient per unit of mass than regular cooling using the atmosphere or hydrosphere here on Earth.
Well. 2.7K is cold
oh good, Wall-E levels of space polution
[dead]
Even trash disposal is possible! Dispose all trash in space !!
It was a significant progress, but I won't call it "nailed it". As there was an damage or explosion on re-entry where the skirt of the starship got damaged. And we could see pretty significant damage on one of the fins.
Nailing it would be without the things above.
The explosion was unexpected and (as far as I know at the moment) unexplained, but they flew the mission at the edge of the envelope, and with a variety of different materials/missing bits on purpose, to better understand where the edge is. Everything that happened (maybe even including the explosion, we'll see in the final analysis) was, as far as we know, within the plan.
The biggest can't-miss milestone was the flawless engine restart. That gives them the go-ahead to hit orbit on the next flight.
I'd say the payload door situation is a considerable success, at least as big as the relight itself.
I saw one of the dummy satellites bump into the edge of the door on the way out.
They were testing different catapult configurations. Seems clear that one is a no-go but others looked good.
Actually existing Starlink satellites regularly bu p into each other when lobbed in benches by the Falcon 9.
They are built to tolerate that, resulting in much better launch volume and weight utilization (sats are stacked on top of each other & held in place by rods that are then released).
The Starship Starlink release demo was quite tame in comparison to that. ;-)
> The explosion was unexpected
Is it really unexpected that an extremely hot metal pressure tank will rupture when plunged into water?
Since the ship is designed to be caught by a tower and not be plunged into water at all, it doesn't seem like this would be an issue in normal operations.
Different explosion, the one the parent comment is talking about happened earlier in reentry
The deployment system was interesting, how the last one in the layer would go back then forward before releasing.
It looked like something one would cobble together from a garage opener and weld together a bunch of rebar
You should have seen the first tech demonstrator for the Raptor engine (the family that powers Starship). It was basically a water tower (built out in the desert, welded by people specialising in building water towers). But it flew, and it landed, and then it served as a lights & camera mount for the field for a few years.
Starhopper is still there, on a parking lot next to the launch site. :)
https://starship-spacex.fandom.com/wiki/Starhopper
Keep in mind the ship diameter is like 30 feet. It may not seem like that from a camera view, but that pez dispenser is pretty massive.
I wonder how many potential designs they considered. You've got the mass of the doors and structure of the ship to consider, the mass of the cargo, actuators for both, the arrangement of cargo in the ship, all of which have interconnected tradeoffs.
Also add pressure management, warping of the dispenser and ship hull & thermal expansion.
And fornlong duration missions also lubricant evaporation, possibility of vacuum welding & atomic oxygen reactions if you spend long in low Earth orbit. :)
The fun thing is that as long as you have the requirements and acceptance right, this could still be solved with a garage door opener and welded rebar :-D
Reminds me of early Google DIY rack PCs. [1]

SpaceX has two big things going for it: Starship/Raptor factories churning them out cheap, and themselves as a paying customer in Starlink who can dogfood a risky new launch platform.
Now that they're demoed pez-dispensing v3 dummy Starlinks, I'd assume they'll start launching real ones within ~1-3 months. At that point as long as they can deliver payload to orbit and catch the booster the program is operational and they'll start switching their own Falcon 9 launches over.
The HLS timeline is definitely dicey, but whether Starship winds up being the blocker remains to be seen. Otherwise they've now succeeded enough to "lean launch" Starship with equal/better capabilities to any other existing orbital rocket, and Starlink can fund indefinite further tests/iterations on the rest of their roadmap features (which no one else has).
> I'd assume they'll start launching real ones within ~1-3 months
I think it's still a bit early for that given that they've only had one successful flight and are still testing lots of new design changes, but I think you're right that the capabilities they've already demonstrated are probably enough to make Starship commercially viable even if literally none of the other revolutionary improvements they're working on pan out.
Falcon 9 doesn't recover the 2nd stage at all, and it's already by far the least expensive rocket out there in terms of cost/kg.
Yes, although it was stated before the flight that they were intentionally flying with some heat tiles removed and with a more aggressive profile to test some outer limits.
They even removed some near fuel tanks. In the past the missing tiles were in less critical areas.
I'm surprised they didn't take less risks just to avoid a narrative of failure.
> I'm surprised they didn't take less risks just to avoid a narrative of failure.
That's the advantage of being privately owned. "Vibes" (hah) don't matter. Public opinion doesn't matter. What matters is executing on your vision / goals. And they're doing that.
The fact that they're bringing in loads of cash from Starlink surely helps. They haven't had the need to raise money in a while, now.
They literally just took another 1.5 billion in tax payer money on top of previous billions. They are cash flow negative and only have a multi year runway
Selling rockets to the government is not receiving gifts of taxpayer money.
I think you're wrong saying they are cash flow negative. Both Starlink and payload launching business are profitable in SpaceX.
That's probably the first step on the path to stagnation.
There's a lot more eyes on them now a days, and Musk is much more well known, so it creates a lot more drama - but they've done the exact same process with everything. They even published a montage of failures [1] on the way to their first successful landing 'back in the day.' It was fiery, but mostly peaceful. They didn't even hit a shark!
[1] - https://www.youtube.com/watch?v=bvim4rsNHkQ
Unless they took extra risks to hedge against the string of failures continuing. "Yes we blew up three times in a row, but this time we meant to do that, so it's a success" sounds an awful lot better than "We did everything we possibly could to prevent it from blowing up this time but it still did"
Why would they need to care about narrative at this point?
It's privately own, might as well learn as much as possible with each dollar spent.
I'm certain they don't care about the narrative because ultimately even though yesterday was a big success some places had headlines that really downplayed it
Does it really seem like Elon cares about public opinion at this point?
He acts like he cares a lot, comes across to me as someone deeply insecure and unhappy but I’m not qualified to diagnose him.
[dead]
Fin damage isn't ideal, but even if they had to replace the fins every flight, the cost would be quite low in comparison to replacing the entire second stage, which is necessary on the Falcon 9.
I think this launch showed they were very robust. Engines went out on booster and ship which they can compensate for. A small explosion and a half melted fin didn't seem to affect the splashdown sequence or target.
I think there was just one unexpected engine out on the booster during launch. Starship engines worked without any issues on this flight AFAIK. :)
The flight looked good, but I was wondering if the ship splashdown burn was the ideal one or an alternate one from a damaged engine. To me it looked like they were working around a damaged engine.
The splashdown burn was specifically set up that way to test the fallback scenario for a failure of one of the inner ring engines. The fact that the ship landed almost on top of the target buoy shows it was a success.
I would say they nailed it based on achieving all the objectives they stated before the launch.
The fins were intentional… they said on the live stream they were testing different types of tiles and missing tiles to see how the substructure would behave.
The damage was visible long before the explosion, during ascent (not sure if anyone has explained how it happened). Though your point still stands.
I was very surprised that that flap still held up during the stress testing on atmospheric re-entry.
I view it differently. The ship not only survived, but also accomplished all of its mission objectives despite those issues. What this shows is that it has remarkable resilience, which is a really important considering the types of forces it will be subject to during future missions.
> And we could see pretty significant damage on one of the fin
They specifically said they're testing lighter fins to see how much they would hold. Let's not invent problems when it's an experiment that was clearly stated.
Is it common to plan an explosion to test how something will react in these launches? Honest question, I know nothing about rockets.
In SRE, we have chaos engineering so I'm wondering if it's the same concept.
I don't think "plan an explosion" is quite right.
They planned a test that would subject various components to stress levels outside of the normal mission profile. The various specific failures that resulted from that may be within expectations but not necessarily planned.
In engineering you want to know that a design will not just succeed at its rated limit, but have some margin percentage of safety above that. To measure that margin often involves destructive tests.
SpaceX's development methods differ a bit from more traditional rocket development by performing some of these potentially destructive tests with full-scale articles in real flight scenarios as part of an iterative process.
I'd say it's a mixture of chaos engineering and load testing. They know what performance they need for a safe flight, but they want to know how much margin of error they've got (and how close their simulations are), and what they can do to optimise.
It's a different apporach to say the Apollo program, where they did heavy up-front analysis, at the expense of cost-efficiency, speed, and innovation. They had one-shot for a flight, otherwise that's several $bn up in flames.
Even with the last few mishaps, it's an approach that seems to be working. If you look at Starship and Falcon's journey in comparison to SLS and Blue Origin, they have done so much in such a short timespan.
It's very common for extremely hot metal pressure tanks to rupture when plunged into water.
I understand but I'm asking more from a process perspective. If these are planned.
In complex systems testing by perturbing the environment is the easiest, simplest and uncovers most relevant issues with design. They knew something would fail, but not necessarily what exactly or in which sequence. They can now reject or accept their hypotheses and improve their models.
Testing to destruction is used quite often to discover the final limits of materials and machines.
They compromised the ship to study failures of that nature.
For Starlink deploys (or other commercial launches) re-entry isn't too critical. Starship is still an order of magnitude cheaper than other launch vehicles even without Stage 2 re-use.
They'll need a higher bar for Artemis but frankly Starship is not the only critical bottleneck there and it's not SpaceX's main financial driver.
Nah, they nailed it.

> "Why didn't just get it right on their first test", really? People can't even get a regex right the first time.
The comment you replied to didn't say that. And this isn't the first test.
I think their comment was reasonable. It was a successful mission that met the stated objectives and demonstrated progress. But it wasn't perfect, and there is definitely more progress to be made for Starship to be a reliable operational launch system.
[flagged]
Amazing achievement. Just watching no that giant thing lift off is a great feeling.
It's pretty remarkable progress. Slowly but surely, they're getting it done. I predict they'll have a full working version by 2027. By 2028, they'll have regular reusable flights.
My personal estimates are similar. For anyone that followed Falcon 9 development (from the first Falcon 1 launches), it’s really similar. I remember boom after boom until one day they cracked the problem and reusable boosters became the status quo.
I got tingles when the first booster landed on the drone ship, because I knew access to space had just changed in a fundamental way.
Comparing Falcon 9 to Starship is a dangerous mistake.
First, the time frames are way off. Development of the Falcon 9 took ~5 years (2005 to 2010). The first reused booster came much later (2017?).
Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was.
Third, Starship is significantly more complicated technology-wise, being methane based. There are reasons to do this but it then requires cooling both propellants (instead of just liquid oxygen and RP-1 ie kerosene with the Falcon 9(.
Fourth, Starship has to compete with somethingg Falcon 9 never did: Falcon 9. Falcon 9 is now the most succcessful and cheapest launch platform in history. It is the reliable workhorse of the industry and relatively cheap to launch. Its reuse is proven.
Fifth, the market for Starship is unproven. We can compare it to other launch systems for heavy payloads, most notably the Falcon Heavy, which I believe has only had ~12 launches in almost a decade (compared to the 100+ Falcon 9 launches every year).
You could argue SpaceX will steer customers to Starship but there'll be other competitors (to the Falcon 9) by then.
Lastly, Starship is still so far from being human-rated. So much of the needed tech (eg refuelling in orbit) hasn't even begun testing yet. I can easily see this taking another decade at least.
> Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was
They are already reusing boosters, so it might already be cheaper than F9 before booster reuse. Once they start reusing the ships, it will be cheaper than F9 with booster reuse because F9 has to build a new second stage each launch.
> Fifth, the market for Starship is unproven
The market for Starship is proven by SpaceX itself. The Starship can add 20x the Starlink network capacity per launch as F9. There are currently around 100 Starlink launches per year, so the market couldn't be more proven.
> Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was.
The launch cost of a Starship today is high, especially if you include development costs, but Musk's goal is a marginal launch cost of ~$1M. A Falcon 9's launch price is ~$70M; Musk claims a "best case" marginal Falcon 9 launch costs ~$15M.
Yeah if those numbers are even in the correct order of magnitude Starlink will become a literal money printer. Any commercial or government launch contracts will be cherries on top. Bezos will be our only hope for affordable satellite internet.
Just look at their launch cadence for falcon 9.

It’s a bunch of starlink missions. With some dedicated and rideshare missions.
I know it's a similar size to the Saturn V, but something about the Saturn V just seems grander to me. Maybe it's the paint job?
Frankly, it kind of blows my mind what the US pulled off in the late 60's, early 70's with the technology and materials of the time.
I too find it difficult to appreciate the scale of the thing. The lack of features doesn't help I think.
That said, I hadn't fully appreciated the size of Saturn V either until I saw it in person in the museum. Like, I had felt it was big, but it was big.
They had virtually infinite budget at the time. SpaceX is much, much cheaper.
Is it though? I'm not knowledgeable on this at all, but it _seems_ like Space X is blowing up a lot more expensive equipment compared to NASA back in the space race days. Genuinely curious how it compares and how true my outsider impression is.
It's not as expensive as it looks, Starship plus booster costs around 100 million. A Saturn V Apollo mission cost 185 million in 1969 which, according to https://en.wikipedia.org/wiki/Saturn_V#Cost, would now be a bit less than a billion dollars.
Also, SpaceX is not building rockets, they are building a rocket factory. If they succeed they will have lowered the cost of putting stuff into space by an order of magnitude. The potential rewards are huge.
Yes but at this point the upper stage is barely a spaceship. Mostly an empty shell. And they have spent $10 billion so far on something that barely flies.
R&D and prototyping is an up-front expense. Amortization over many units spreads out the costs to long term profitability. Does SpaceX have that kind of time, though? A prospective global depression would dry up the capital for funding Starship development.
Clearly this is not true. I'm not even sure what about it is not true, but there must be some reason Musk paid Trump to destroy his competition.
https://orbitaltoday.com/2022/09/05/starship-vs-saturn-v-cho... claims Saturn V development cost $50 billion vs Starship at $5 billion. Not to mention the cost per mission once Starship is fully functioning and reusable.
They can spend numerous ships testing because the cost is dramatically lower per ship.
As with any manufactured item, high volume and iterative design improves the production process and finished product.
There's more of a production line when building Starships, with modern mechanised tooling - much of it computerised and 100% repeatable. There's been at least 10 so far, vs only 15 Saturn V, 3 of which were ground tested.
https://en.wikipedia.org/wiki/Saturn_V
saturn v was about 30B in 2025 dollars. starship has cost on the order of 5B so far.
raptor engines are designed to be cost efficient, as is the rolled steel? that is used for the fuselage
Not to mention the mountain of prior art to work off of...
It's way harder to do it the first time.
There's absolutely loads being done for the first time here. Not least of which: running this r&d off commercial contracts instead of directly off taxpayer money.
The mountain of prior art being... one rocket that had very different requirements?
Apollo also invented, funded and productized a lot of modern embedded computing and computer manufacturing, to keep in our lane here. Obviously SpaceX has access to a very different tech environment that yes, Apollo helped push forward.
Manufacturing the Apollo Guidance Computer (which wasn't in the rocket per-se, but was wired up to it and could fly the rocket in certain scenarios) alone consumed around 40% of the US' entire IC production capacity at the time.
SpaceX IS doing lots of important things for the first time.
And don't nobody mention Falcon Heavy. 11 successful flights and a proven 60% of the spec payload of Starship.
Cost comparisons are strange because Starship isn't finished.
Whenever we talk about space flight, this movie quote comes to mind: "You know we're sitting on four million pounds of fuel, one nuclear weapon and a thing that has 270,000 moving parts built by the lowest bidder."
Starship has considerably fewer moving parts. And googling 'evolution of raptor engines' gives you some pretty stark images on how simpler things look, in principle.
Love it, great job SpaceX!
I watched the Martian again the other day and I marveled about how much has changed. With Starship progress, almost none of the plot really makes sense (bespoke vehicles and payloads etc). The first mars expeditions will probably be stocked with a thousand tons of gear, enough to easily last a guy 5 years. And if some dude were stranded on Mars, SpaceX could start lobbing things in his direction within maybe 30 days?
The Martian is a vision for a 2035 mission from 2011. We seem likely to beat that!
> SpaceX could start lobbing things in his direction within maybe 30 days?
If Earth and Mars are on opposite ends of the sun, nobody is going anywhere within 30 days. I do not see how anything will change from the one transfer window per ~2 years for the foreseeable future
'lobbing things' i.e launching things, OP didnt mean it would reach there in 30 days.
You couldn't start launching things in 30 days, you need to wait for a launch window, which happens every ~2 years. The transit times are on top of that.
The launch windows are for the most fuel efficient transfer. You can still launch outside of the window if you’re willing to pay the cost elsewhere.
While this doesn't apply in the scenario that the person you're responding to has given there are ways to get many more transfer windows between Mars and Earth using Aldrin Cyclers.
> The first mars expeditions will probably be stocked with a thousand tons of gear, enough to easily last a guy 5 years.
> The Martian is a vision for a 2035 mission from 2011. We seem likely to beat that!
What, exactly, is that guy doing for those five years? We don't know how to terraform Mars, and it's questionable what having someone on the surface will add to the knowledge we have of surface composition. And then what? That equipment is still on earth - after it's built.
Oh, and how's he planning to get off Mars?
I would comfortably make a $100 bet that there is no chance that we have sent a manned mission to even orbit Mars by 2035, let alone are "settling" it.
At a minimum, it would be a major test of the habitat's ability to support human life for 5 years.
A major activity for the Martian would be exploring the location and prospecting for necessary raw materials, like digging for water.
https://idlewords.com/2025/02/the_shape_of_a_mars_mission.ht...
From this:
> The effect of this no-abort condition is to make Mars mission design acutely risk-averse.
"Acutely risk-averse" is not SpaceX.
And being acutely risk-averse also underscores my point. If we are actually acutely risk-averse, we aren't going from "still test-flighting and developing the launch vehicle" to "manned mission" in 9.5 years.
> What, exactly, is that guy doing for those five years?
Waiting to be rescued. We're not talking about sending one guy to mars for funsies, we're talking about one person left after an emergency. In the book he gets off mars by going to the launcher staged for the next mission, which again is a case of prepositioning extra hardware before sending someone to the planet.
If you assume a team of 5 people with an intended stay of 6 months, 5 years of supplies is a factor of safety of 2. If you send enough supplies to keep the whole team alive till the next launch window, that would keep a single person alive for about 2 decades (ignoring potential storage lifetimes).
> In the book he gets off mars by going to the launcher staged for the next mission, which again is a case of prepositioning extra hardware before sending someone to the planet.
There's a "world" of difference between the Eagle returning to Apollo 11 in low lunar orbit, and prepositioning a interplanetary vehicle capable of Mars-Earth (after getting from Earth to Mars), landing it (and without live feedback/guidance, because of roundtrip radio time, not to mention, this isn't some Rover, it's a really large rocket) well in advance of the manned mission (8 month flight time, IIRC, which means realistically it's going to be hanging out on Mars for a minimum of 6 years, even if you launch the manned mission within a couple of months of its arrival, which seems ... risky) and hoping that one solo astronaut is going to be capable of fixing any issues that arose during landing or during its ~year, untouched, and five years of his habitation.
Martian dust storms are a thing. "Smaller", continent-sized ones lasting weeks at a time, hit a few times a years. And then you have the planet-covering ones.
> Individual dust particles on Mars are very small and slightly electrostatic, so they stick to the surfaces they contact like Styrofoam packing peanuts.
So many issues. We're not solving these by 2035.
We are still at the point where unmanned, tiny craft with none of these challenges routinely fail. We're making progress, but we're not making that much progress, not that quickly.

Given the results of test 10 (successful splash down of Starship), any ideas what test 11 will entail? Could we be looking at a chopstick catch of the Starship itself?
They're probably gonna keep wasting ships until they've got the exact limits of their capability established.
I know it seems counterintuitive to everyone who grew up in the era of the space shuttle, but the ship is the cheap part, the giant booster is the expensive part.
The ship has a way longer cycle time so starship unit costs are going to dominate fleet construction cost despite being the cheaper unit so knowing exactly how hard you can run them is very valuable information it's worth gleaning by wasting some units early on.
They only have one more shipv2 right now. The next ones are shipv3. So my guess is that a ship catch doesn't make sense, since they're changing the architecture on the next ones. Would make sense to continue with limit finding (it's a disposable launch anyway, old gear) on things that carry over (i.e. thermal protection, ablative materials, crazy angles, etc)
One interesting point is if they actually go for orbit. It would take just a few more seconds to reach something like 200+km / 100km, a place where they could deploy some v3 Starlinks and gather data from the launch (i.e. vibrations, health, dinging on the door, etc). It would be a test where they get more data that's transferable to the new architecture, and relatively low risk of getting stuck in orbit. (low perigee would mean eventual re-entry anyway, hopefully over the ocean) The sats can probably raise themselves from there.
Like you said, flight 11 has the last V2 and since V3 is not compatible with the existing pad A (only the new pad B that is being finished atm), it would be a nice opportunity to try the ship catch because cratering the old pad A and/or its tower wouldn't be that much of a deal. The entire Pad A has to be replaced anyways.
What did they change about the pad between 2 and 3?
Not sure about the pad, but the V3 ship has the catch points on the fins for example.
I wouldn't expect that on the next flight.
One option is they can run it again with the data gained from missing tiles etc. and see if there is an improvement.
They could also do a similar flight but with an actual orbital insertion and de-orbit if they are confident in the odds of success of the de-orbit burn.
Landing the ship at the launch site means overflying land and potentially populated areas, so I think they're going to want to demonstrate successful control, re-entry, and landing from orbit a few times before attempting that.
That's not out of reach/plans according to Wikipedia: https://en.wikipedia.org/wiki/List_of_Starship_launches#Futu...
But I agree with you, I'd rather have test flight 11 demonstrate at least another successful reentry with no issues (they had a non-fatal explosion on ship reentry in flight 10) before attempting to catch the booster AND landing the ship.
The money is in Starlink, so maybe they'll want to make orbit having demonstrated successful relights and payload door operation?
Probably the same as 10, but with SHB catch.
Amazing progress. SpaceX speed is enviable.
"That was absolutely incredible," SpaceX Build Reliability Engineer Amanda Lee said during live launch commentary. "A huge congrats to all the teams here."
"Great work by the SpaceX team!!!" SpaceX CEO Elon Musk wrote on X after the flight.
Amazing accomplishment. Always a thrill to watch live.
SpaceX conducted 134 launches in 2024 and is targeting a record-breaking 160-170 orbital launches in 2025.

How much money did it cost to orbit Saturn V (including R&D of course)?
According to wikipedia, the entire cost of the saturn v project was US$185 million, equivalent to US$33.6 billion today. That's from R&D to all launches
You mis-copied the numbers for one launch. Wiki says:
> Project cost US$6.417 billion (equivalent to $33.6 billion in 2023)
> Cost per launch US$185 million (equivalent to $969 million in 2023)
That a manned Apollo mission would/did cost under a billion dollars (todays money) is surprisingly cheap. A single Artemis launch using the Space Launch System (SLS) costs an eye watering $4 billions.
Different metric:
> [1966] NASA received its largest total budget of $4.5 billion, about 0.5 percent of the gross domestic product (GDP) of the United States at that time.
Using that metric NASA yearly budget would with todays GDP be $150 billion dollars.
Some of this was the overall urgency of the 1960s space race, that people were motivated to cut through red tape and get it done, and I know it's also argued that modern safety standards and requirements around supply chain, real time monitoring, system redundancy, etc all complicate things and raise costs.
That said, it would be interesting to have someone really knowledgeable go over what it is that Artemis has and Saturn V didn't, and then break them down and assign each an approximate proportion of the cost delta.
In recent years, NASA’s budget has hovered around $25–27 billion.
This represents less than 0.5% of the total U.S. federal budget, though it’s one of the most visible and impactful science agencies
Part of the SLS cost comes from trying to save money. Yearly budgets are kept low, which spreads out the work over a long time. This makes everything cost more, but the politicians only care about the yearly spending.
SLS is also a pretty weird design due to reusing Shuttle components for a completely different kind of launcher. This saves development costs (maybe) by using existing stuff that has already been developed, but the unsuitability of those components for this system increases per-launch costs. Once NASA runs out of old Shuttle engines, manufacturing new ones is going to cost $100 million apiece if not more, and each launch needs four of them. It was OK for Shuttle engines to be expensive since they were supposed to be amortized over hundreds of flights (and in practice were actually amortized across at least tens of flights) but now they’re being used in expendable launches. If Starship even comes remotely close to its goals, an entire launch will cost less than a single SLS engine.
I had understood that reusing shuttle parts was more about keeping congressional districts (that make the parts) happy, and thus securing votes for funding.
facepalm not sure how I misread that
Yes, I also can look trivial stuff up. That would include costs after the rocket first orbited the Earth, so it doesn't answer my question.
No need to be condescending when communication is ambiguous. Your question can be better phrased as, "How much did it cost for Saturn V to reach the point where it could successfully orbit?" which I assume means "how much did it cost up to and including Apollo 4?"
Wouldn't the cost of all of Mercury and Gemini missions need to be included in this as they could not have Apollo without the others first.
And then we also need to add the costs of the V2, because surely we wouldn't have had Mercury and Gemini without the V2 first... and of course we wouldn't have that if the Chinese hadn't developed the first rockets in the 13th century, so we need to figure out their development costs. Where does it stop?
So you think SpaceX isn't building on the shoulders of giants?
There are teams of incredible engineers working there because NASA paved the way.
Those weren't on the Saturn V, though. They were various rockets for Mercury, and Titan II for Gemini.
Do you think they would/could have built the Saturn V without building the other engines first?
I think as phrased this is going to get way too pedantic. But I think it raises a larger point which is worthy to consider.
Presumably what we're trying to get at is, in broad strokes, "is Starship more cost-effective to develop than Saturn V" (and I assume the follow-on for that will be to compare the "NASA approach" vs the "SpaceX approach")
But you raise a good point in that the baseline playing field is completely different. The existing knowledge each program started with, be it in materials science, understanding of rocket combustion, heat shield technology, electronics, simulation ability, you name it, it's completely different. So we can find and pull out whatever numbers, but I don't think it's possible for them to say anything meaningful for comparison on their own.
>but I don't think it's possible for them to say anything meaningful for comparison on their own.
It depends on how different they are. Saturn V was launched 13 times in total. Starship is already 75% of the way there and hasn't orbited once. Ignoring R&D and just going by launch costs alone, that's USD 4B (2025) to orbit 1 Saturn V, vs USD x to orbit 1 Starship, where x >= 1B.
Starship has already reached orbit many times but places itself on a suborbital trajectory to intentionally test re-entry and landing which it has done successfully several times.
> Saturn V was launched 13 times in total. Starship is already 75% of the way there
Apollo 1 - lost on the launch pad, crew killed. very bad Apollo 13 - major malfunction causing loss of mission but crew saved. very not bad
Starship - 10 launches 5 failures. No crew ever so that pressure is also not comparable.
Are we really claiming Starship has achieved 75% of the results of Apollo? That's absolutely ludicrous
Starship is 75% of the way to 13 launches. That's just mathematically correct.
And is absolutely useless. Apollo 9-17 went to the moon with human occupants. All but one put men on the surface of the moon. They all returned to Earth with zero fatally exploding ships.
Not one of these triumphant 75% achievement in launch numbers would have had a surviving human. Apollo had 0 practice runs. Starship is nothing but practice runs. To equate the number of launches to something so drastically different is just an exercise in futility that I can only assume you're trolling
> Starship is already 75% of the way there and hasn't orbited once
Read it as "Starship is already 75% of the way to that cost and hasn't orbited once" (you seem to be in agreement)
Dude, when did I say they were triumphant? SpaceX is burning taxpayer money sending empty coke cans on ballistic trajectories for no good reason. My whole point with this line of inquiry has been to point out what a useless waste of resources Starship has been so far.
But who will get to 100 launches first? 1000? Saturn V was in one way a great success that will be remembered for all of history. But in another it was a failure due to your exact statement. It only launched 13 times due to being so expensive as to just not be feasible.
Neither will.
>It only launched 13 times due to being so expensive as to just not be feasible.
"There aren't many uses for such a gigantic rocket. Let's make an even bigger one and hope it works out!"
Actually, "let's build a cheaper one and hope it works out" is the design philosophy here, and it's a very effective one across pretty much all domains. The fact that it's bigger too is mostly incidental to its economic case. You think we would have stopped at Apollo 17 if the same Saturn V was capable of flying Apollo 18 - 30?
Hadn't we already built the Saturn V for Apollo 18, 19, and 20?
If we're going down this road, we'd have to include the global GDP back thousands of years. I asked specifically about Saturn V so I could make a reasonable comparison between it and Starship.
What about the costs paid by the Song dynasty to develop rockets in the 13th century!
Never mind that. Remember that Grug had to die from eating poisonous mushrooms for the first time, all so we could have disposable plastic forks.
How does that matter? It's doing a thing already done nearly 70 years ago but at its own pace.
I bet it will get to the moon cheaper, too, and the Muskonauts will use less expensive lenses than Hasselblads to take photos.
Starship isn't exactly the same as Saturn V. It's bigger, for one.
The reason why it matters is that efficiency matters. It's fine if it takes longer, not so much if it costs way, way more, especially if such a huge rocket has limited applications. And as I understand it the consensus is that Starship (or at least a fully-loaded Starship) will never go to the Moon. Once it's in orbit it takes like twenty refueling launches and space rendezvous to fill it up again so it can make the transfer burn. In other words, it's never happening.
I think that understanding of the consensus is incorrect. The mission plan for Artemis 3 is that a specialized Starship upper stage will be refueled in LEO and then transfer to lunar orbit where it will wait for astronauts arriving on SLS/Orion.
Yes the mission profile is more complex, but that complexity can mostly be settled before the astronauts launch on their mission.
NASA seems to think it is a viable plan which is why they selected SpaceX to execute that part of the mission.
Wikipedia:
> After a multi-phase design effort, on April 16, 2021, NASA selected SpaceX to develop Starship HLS and deliver it to near-rectilinear halo orbit (NRHO) prior to arrival of the crew for use on the Artemis III mission. The delivery requires that Starship HLS be refueled in Earth orbit before boosting to the NRHO, and this refueling requires a pre-positioned propellant depot in Earth orbit that is filled by multiple (at least 14) tanker flights.
I stand by what I said: not happening. I'll believe it when I see it.
Can you imagine if to make a sightseeing trip to another city you had to stop in the middle of the highway and then make 14 round-trips with a second car to fill your first car back up? I can't imagine why someone would approve this plan, other than corruption.
> Can you imagine if to make a sightseeing trip to another city you had to stop in the middle of the highway and then make 14 round-trips with a second car to fill your first car back up?
If the alternative was throwing away and building/buying a new car for every trip? Absolutely.
They said the same about landing a first stage booster - impossible and pointless to attempt. And it just happened for the 400th time yesterday.
False dichotomy - the mission profile dictates the refuelling station and all that, but it never was the only option. Somehow we've decided we needed to be able to do lots of trips to the moon for Artemis, but it's not clear to me that it's such a precious golden oportunity and warrants this spending/impact on the environnenent.
We didn't get to the moon with a refuelling station did we? How come we need one now? We're really seeing 15 starship launches per moon trip as reasonable, rather than just building a single trip program?
The mission itself is nonsensical. The problems are stemming from the SLS, I'll find a link to a relevant source.
> We didn't get to the moon with a refuelling station did we?
No. We did it by throwing away ~98% of the vehicle on the way there.
> How come we need one now?
Because building a new gargantuan tower and tossing that majority of it into the ocean/deep space every time we need to go the moon is not sustainable.
> We're really seeing 15 starship launches per moon trip as reasonable, rather than just building a single trip program
Yes. Because again. The alternative (dictated by physics) is that we expend the whole thing.
And why do we need to do all this? This is the thrust of my point.
Making trips to the moon sustainable is pointless and nonsensical.
Edit0: good read https://news.ycombinator.com/item?id=40410404
>The alternative (dictated by physics) is that we expend the whole thing.
We can also, you know, not. We could put that money to something here on Earth instead of burning it up.
The Apollo missions landed two crew members in a tin can with extreme limits on what weight they could bring with them in either direction.
A single trip launch will always be constrained like this due to the tyranny of the rocket equation.
A modular mission system with multiple launches is the best way to expand capabilities and enable things like landing larger payloads for more advanced or long-term missions.
IIRC, the expected return payload for this is lighter than Apollo. In no small part because they're dropping all their return fuel and their entire return vehicle into the Moon's gravity well, rather than leaving it in orbit. Subjecting themselves to extra abuse from the good ol' rocket equation.
One of many wacked-out things about the plan.
The vehicle that returns to Earth is Orion which stays in NRHO and does not bring its fuel to the lunar surface.
Return payload constraints are probably from using Orion as the return vehicle. Mass to the surface is much higher than Apollo since that is launched separate from the crew.
I thought the return vehicle was a to-be-developed direct-return vehicle from both SpaceX and Blue Origin (both got contracts, and supposedly both's versions will fly)?
[EDIT] Apparently there are multiple plans involving even more spacecraft, because why not I guess? It's as you describe for Artemis III, but then gets way more complicated with Artemis IV, involving more spacecraft for some reason.
As far as I know all of the known Artemis mission profiles only use the lunar lander to shuttle from NRHO (lunar orbit / gateway station location) to the lunar surface and back. All crew return is planned to be done with Orion for now.
NASA has optioned an additional lander from Blue Origin but that would be taking the same role as SpaceX's lander, shuttling from lunar orbit to the surface and back to lunar orbit.
There's never going to be long-term crewed missions to the Moon. It has no scientific value. Even the little exploration we did in the '60s and '70s were a dubious proposition. There's not that much we could do by sending people that we couldn't do by sending robots.
If you think there's no value to returning to the moon, building a base, etc. then fine. But you keep moving the goalposts of what you are taking issue with here.
I didn't move any goalposts.
1. Starship is never going to be usable for a Moon mission.
2. There's little scientific value in Moon missions.
3. There's never going to be long-term missions to the Moon.
I maintain all three simultaneously.
And yet the boosters are not being reused. They're just making brand new engines for every launch. If we're generous they're being dismantled and recycled.
They were talking about Falcon 9, which is absolutely being reused.
Alright, if we're talking about Falcon 9, I don't know what the cost savings are for a reusable rocket, or if there are any. If someone has that data, feel free to provide it.
> As of 2024, SpaceX's internal costs for a Falcon 9 launch are estimated between $15 million[186] and $28 million,[185] factoring in workforce expenses, refurbishment, assembly, operations, and facility depreciation.[187] These efficiencies are primarily due to the reuse of first-stage boosters and payload fairings.[188] The second stage, which is not reused, is believed to be the largest expense per launch, with the company's COO stating that each costs $12 million to produce.[189]
From wikipedia: https://en.wikipedia.org/wiki/Falcon_9#Pricing
There are a lot of variables, but very roughly, the Falcon 9 has cut launch costs in half compared to its competitors.
How did the fuel you put in your car get there? Your car didn't come with all of the fuel for the trip, nor did it spawn at the gas pump.
It was pumped, shipped, refined, and trucked to that point using a complex supply chain, enabling your final trip to happen with one fuel transfer.
The mission is wildly more complicated than the Apollo missions. There's a whole oddball-orbit space station that has to be placed as a way-station, for one thing, and none of that's happened yet (remember how long it took to build the ISS?). Also, landing all your return fuel instead of leaving it in orbit, so a way heavier lander (with a smaller return payload than Apollo!), which is a pain in the ass. Multiple space ships launched by different rocket systems involved. The SLS still has to be finished for it to go forward. Orbital refueling of large fuel tanks is a hard problem that remains unsolved, and this goes nowhere without fixing that. The contracts for the return vehicles are disturbingly light on parts about making sure they can reliably work, including surviving re-entry.
I'm with you. Not happening. We're more likely to come up with a totally different, simpler plan, and do that instead, before this happens.
> landing all of your return fuel
The fuel that is landed is used to get back from the lunar surface to lunar orbit, not to return to Earth. That fuel stays with Orion in NRHO.
You can easily mathematically prove that orbital refueling increases mission efficiency. This is a simple fact, it's not about Starship or whatever. Your analogy does not hold.
> I stand by what I said: not happening. I'll believe it when I see it.
And it's totally valid for you to have that opinion. But it's your opinion, not "the consensus."
"It's fine if it takes longer, not so much if it costs way, way more, especially if such a huge rocket has limited applications."
Taking longer at lower cost is a great trade-off for Starship but wasn't for Saturn V. The main driver for Saturn V was the space race against the Soviet Union. Economic interests played a very small role. It was all about being first and compensating for the Sputnik shock.
Adding to previous comment, looks like the cost per launch when the system was up and running was ~1billion USD inflation adjusted. I'm going to assume Starship will beat that easily.
Maybe, but remember that getting astronauts to the moon and back took a single Saturn V launch but with Starship, it will take (at least) 10 flights for refueling, possibly as many as 20. So each launch has to be much cheaper to beat Saturn V for the full mission.
Nobody but SpaceX knows how much each Starship test costs but the estimates online range from $50 million to $200 million. Presumably, whatever the actual cost, they're more expensive right now while they're redesigning bits and doing custom, one-off work for each flight but it has a long way to go to beat Saturn V for the full mission.
A starship mission to the moon will land over 100tons of cargo. Saturn V could get roughly 5tons to the surface. Its an entirely different class of operation.
That's LEO, not to lunar orbit and entry. Saturn V had a maximum lift capacity of 310,000 lb (140,000 kg) to low Earth orbit (LEO) and could deliver approximately 50 tons (45,000 kg) of payload to the Moon.
Looks like Starship test flights are already beating that $1 billion per-launch cost (I'm seeing estimates in the $100-500 million range), and they'd like to get the marginal cost down to ~$10 million.
I'm confused -- how is it meaningful to compare the cost of Starship test flights with operational Saturn V missions?
There were no Saturn V test flights like Starship is doing, that I can find info on. Wikipedia lists 3 tests before Apollo 4, which was the first full launch.
From context I interpreted GP to be somehow concluding that Starship is "cheaper" (these test flights are "beating" the price tag of the Saturn V launches), I'm gently pointing out I don't think that is a reasonable conclusion to draw based on empty suborbital test flights vs. taking humans to the moon and back
It would seem no one has the information I originally requested. All we have to go on for Saturn V is a per-launch cost where we don't know what's included. I agree it's an apples-to-oranges comparison, but it seems to be all we have.
The downvotes here are undeserved.
There is nothing wrong with this question. Zero.
Stop eroding this site's community.
And maybe more interesting. How much did it cost them to get this far vs the sls?
You can't really compare them because SLS was a jobs program intended to spread out contracts across many states by reusing suppliers from shuttle programs. Cheap? No. Wasteful? also no. Most of that money went back into those economies.
That's not how it works. If you pay people to dig a giant hole in the ground and then fill it back in, that money "goes back into the economy" but that doesn't mean it's not wasteful.
Ahh, much like the economy has grown so much because the government gave people money and shovel to dig and refill holes. Went back into the economy, must've been a good move. Let's not bother considering what else could've been done with the money.
> Wasteful? also no. Most of that money went back into those economies.
If the government 100B to dig a big hole and fill it up again, that money would also "go back into those economies". Does that mean it wouldn't be wasteful?
The money could have gone into those economies while also securing a productive accomplishment (or more productive accomplishments depending on your opinion of SLS). Factories could have been retooled and workers could have been retrained to produce things of greater value instead of deliberately keeping them obsolete. It's still wasteful even if not completely useless.
It's a very cool rocket and this success is a nice change of pace from the past several failures. However, I just have to say:
> Mars rocket
Very dubious. If you disregard all the SpaceX marketting talk and just go by what they're building, then it's a rocket meant for launching very large satellite constellations as cheap as possible.
The only reason they're doing full reusability is to enable Mars missions. Had they only wanted cheap flights for satellite constellations they could have launched with what they have now (i.e. reusable booster and single use starship), and it would be cheaper than anything on the market with huge upmass capabilities.
Something that I rarely see mentioned about SpaceX's goals and financial viability of a reusable Starship is how significant of a boost they get to their talent pool by working on the absolute bleeding edge on things that seem impossible. People go work at SpaceX because they work on crazy things like Starship instead of only working to make "cheap flights for satellite missions". SpaceX attracts the absolute cream of the crop (at below market rates even but that's besides the point) and those people work better/harder than they ever would working on more boring goals. It's the power of vision and motivation.
That doesn't mean they're going to achieve full reusability, although obviously it looks more and more likely.
The constellations they can launch now are only a small fraction of the size they aspire to launch. Their plans for Starlink alone call for almost 10x as many satellites as they currently have. Then there are all the other constellations they might launch in addition to Starlink, including defense contracts that might call for rapid replenishment of expended/destroyed satellites.
As for Mars, Starship might be ready for that in a few years (a year ago I was saying in a year or two, but I've kicked that back). But where are the Mars customers? Who is developing Mars habitation plans and hardware that will be ready in even twenty years? Commercial demand for large satellite constellations obviously exists. Demand for Mars colonization is nonexistent, it exists only in the hopes and dreams of sci-fi junkies.
I really hope I'm wrong, because I'm a sci-fi junkie!
I watched every minute of it. It was awesome. Bravo Zulu SpaceX.
Incredible achievement, but what is more incredible is how many people (including almost all of my friends circle) have started rooting for SpaceX to fail due to the shenanigans of its founder.
I think as a culture we've lost the ability to compartmentalize. We should be able to criticize and even despise the head of a company, and at the same time celebrate when the intelligence and hard work of the countless smart and hard-working people at that company push the boundaries of what is possible for humanity.
Socialize the adoration, privatize the benefits. Should peasants be proud of their kings palace?
If the king managed to build their palace in the clouds? Yes. That’s a pretty awesome achievement. Not the kings’s achievement, but the achievement stands.

I am rooting for them all. I don't need to like the founder, or his politics. I understand that Gwynne Shotwell and so many others are behind much of the progress.
Shenanigans of its founder being falsely accused of doing a Nazi salute when he was just waiving and not agreeing with certain peoples politics. When someone tries to compare someone to the most evil person that has ever existed then odds are that person is lying through their teeth. On one had we have a 'wave,' literally, and on the other hand we have genocide. It's incredible to me how many people choose not to see through the lies about Elon Musk, even though they have the capability, and to this day think he is a nazi.
I'm rooting for SpaceX to succeed, and there are plenty of people like me.
This is not to condemn or argue with anyone who feels differently. But I think we need to be more visible.
I mostly hope that Blue Origin will be a worthy competitor.
For me what this shows that the most important thing for a CEO to be successful is to have money, a vison (no matter how unrealistic or unnecessary) and a cult personality. Nothing else matters. Also it shows that with enough virtual money (I.e.: massively overblown Tesla stock) you can do just about anything.
Fun trivia fact of the day: BO was founded 2 years _before_ SpaceX. 25 years later, SpaceX has revolutionized the launch industry. Meanwhile, BO has only just had their first (and only) orbital launch at the beginning of this year. It's unclear to me what, if anything BO could do to really catch up at this point.
It's clear that money isn't the defining factor at least. When BO was founded Bezos was the richest man in the world. It has floundered for so long that Musk was able to build up a cult of personality around SpaceX and parlay that into even more money than Bezos.
They each have different failings. Elon is taking an absolutely bullshit approach to project management: if Starship can't meet payload specs, it can't refuel in orbit. Neither of those monumentally risky milestones are even close to being attempted.
Jeff loves measurement and control. So he replaced his experienced aerospace guy with the Alexa guy. Because the Alexa guy works the Amazon way: everything measured and tightly controlled.
Blue Origin was founded before SpaceX, and Jeff Bezos had way more money back then. And when Elon Musk founded SpaceX few people had heard of him and he wasn't even a billionaire. Tesla didn't exist yet, so there was no "massively overblown stock." And where is the "unrealistic vision?" Looks like it turned out to be pretty realistic to me.
Musk has a self-destructive streak where his ambition exceeds his understanding. Examples are over-automation of Tesla Model 3 production, autonomous vehicles without Lidar, and the Cybertruck.
Will Starship every carry a large enough payload to justify the launch cost? I'm skeptical. Musk's Mars fixation is nuts.
You're significantly downplaying the damage done. We can compartmentalize someone having an affair, but election of Trump, support of AfD, and DOGE activity are beyond the pale.
Supporting DOGE is an extremely intelligent thing to do with the amount of debt our government has, 34 TRILLION last time I checked. Supporting a democratically electable party, and eventually the elected president of your choice is the right and moral thing to do by all objective measures, including if you believe in majority rule. Politics is always about disagreement and every generation thinks their disagreements are the most dire, but in reality live moves on. By siding with the literal winning party you are defacto 'moral' in the eyes of the majority.

Did you ever make the effort to ask why he did those things? There’s a possibility that the person who aimed high for team humanity with SpaceX, Tesla and Neuralink was doing exactly the same thing in the examples you named.
https://www.impactcounter.com/dashboard?view=table&sort=titl...
Wernher von Braun had the incredible achievement of shooting the first rocket up to space - the V2.
Thanks to the intelligence and hard work of the countless smart and hard-working people he pushed the boundaries of what is possible for humanity.
Still, I find it hard to accept we should compartmentalize and not think about who those rockets were built for and with what purpose.
>Still, I find it hard to accept we should compartmentalize and not think about who those rockets were built for and with what purpose.
Yet that is exactly what the US did and we got the Saturn V out of doing so.
This is something I am finding myself wrestling with a lot right now.
On the one hand I am a major space nerd and I see the value of what SpaceX is doing. Especially with it really seeming like no one is anywhere near their level. What kind of scientific advancements will be possible once this thing can be used normally and launches like this become commonplace.
But at the same time it is impossible to ignore the Elon situation. And that also directly relates to Trump as well. We are in this bonkers situation where he helped get a largely anti-science administration in power and yet also runs one of the companies that will help science.
It does raise serious questions about whether or not there will be limitations on what types of science can be done. Will they have some line in the sand and say they won't launch satellites that do "X", like maybe monitor climate change.
I think maybe rooting for them to fail is a bit much, but I am sure as hell hoping that someone else can catch up. But in the mean time I will celebrate these achievements cautiously. Recognizing the amazing work that the engineers at SpaceX have put into this, because they do deserve a lot of credit for that.
What if the guy who built the world’s best rocket from scratch, who popularized EVs and brought self-driving tech to the masses, who built brain computer interfaces, dug tunnels, started OpenAI and PayPal…
What if he’s not an idiot?
What if we should actually be listening to what this guy says and considering it?
What if he has the same ability to see what nobody else can see early on in politics…
As he’s shown across the rest of his career?
>What if he’s not an idiot?
Lets evaluate that claim, by first defining what an idiot is, and then looking at his history, all the things he said, and all the things he has done.
Ill skip you the trouble of going through that process - he is very much an idiot.
Don't confuse the ability to throw money at something and make it work through sheer cash burn with actual intelligence.
You don't look for smart people by looking for people who don't do dumb things. Everybody does dumb things. You look for people who have done smart things. Idiots don't do smart things.
No, you evaluate someone's intelligence by comparing what they claim to reality.
For example: https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2F1...

What if his motivations and class interest are not aligned with ours?
Are you the richest man in the world? If not, could it be that what is good for the person in that position is not good for you or most other people?
"Dug tunnels" - one of the most ridiculous boondoggles of any modern industrialist. The Boring Company is a machine for overpromising to get government contracts and underdelivering at exponential scale. He didn't start PayPal, he joined it and ended up getting fired, albeit with a golden parachute that gave him the chance to make more bets.
The "accomplishments" you're listing are mostly just investments that he managed to hype up very well. I'll give him this, he's an excellent huckster. But listen to his opinions? I wouldn't let him tell me what color an orange was.

I love the arrogance that anyone who disagrees with you is “anti-science”.
Please tell us which culture war topics he’s anti-science on.
- Denial of climate change.
- Deletion of economic databases.
- Deletion of public health information and historical weather databases.
- Criticism of vaccine effectivness
- Defunding of health and climate research funds.
- Leaving the largest international research alliances in Climate and Health.
- Defunding of NASA
He called the administration anti-science, which is well grounded claim. But no part of the phrasing implies that "republicans" are anti science or that you are.
Do you mean Trump or Elon? No where am I stating that Elon is anti-science, only that he helped get an anti-science administration in place.
As far as Trump (and the administration in general) being anti-science. I really don't think I need to list examples of this.
It’s honestly amazing what SpaceX has been able to accomplish despite Elon. I mean - look at what his interference has done to Tesla and Twitter. The execs at SpaceX seem like they know how to manage Elon so that their employees are actually able to deliver.
“a satellite that monitors climate change” - really you think Elon Musk is not gonna fly satellites with instruments on them that point downwards?
I am stating an example due to the current political discourse over climate change not that it would be something they specifically would not do.
My point with stating it, is it is not unreasonable to ask the question if we are reliant on a company with someone like Elon owning it is what the company will and will not fly going to be dependent on politics.

Trans men exist and can very much get pregnant.
All you are doing is focusing on the ability to get pregnant to hide being transphobic.
Sounds like you are a bit 'anti-science' yourself.
Are you trying to say that trans men don't exist and somehow lack the ability to get pregnant?
That is pretty basic to proove. Do they identify as male after transitioning? Yes. Do they have a Uterus? Yes. You have a male that can get pregnant (yes I am over simplifying here but whatever)
Now if you wanted to say, a cis male cannot get pregnant. That would be true and no one is attempting to argue otherwise.

I think it’s completely reasonable to be terrified that _that_ man is going to dominate the gravity well.
Spacex under Elon Musk is the precursor to Weyland-Yutani.
Maybe. But also as the founder and largest shareholder is someone willing to funnel money in to far-right causes across Europe, it's really hard to root for the company as a whole.

>The parties opposed to child rape and unreasonable levels of immigration in Europe get called far right because they do scoop up a few far right supporters.
Flagging your comment as well because AFD is definitely not a "few far right supporters".
The issue isn't being against child rape and unreasonable levels of immigration. The issue is that the people who are against that are all liars and charlatans, just like in United States, where the party of moral righteousness and small government is full of child molesters and currently doing some pretty authoritarian shit.
Just because a problem isn't getting addressed as fast as one hopes doesn't mean that one should completely jump ship to literally anyone who offers support for your cause.
At a cost of indiscriminately imprisoning and killing people (remember Korolyov and von Braun)? Surely. he-he.
If Musk does achieve a second foothold for the humanity, then any and all objections to his methods become irrelevant. So far he does deliver. So we wait for the final result.
Also, if you don't know, we've got a war in europe for like 3.5 years already. I'm seriously curious how many times a space-x total program cost since their start in 2000s has been already sunk into that.
Setting aside the founder or company itself, philosophically and ethically the “ends justify any means” concept is deeply flawed.
I agree with your general statement, but in this particular case nobody has credibly articulated any real problem with the means.
Especially when the ends are even less likely to work then Marxism Leninism
But the scientific method does work. So we observe the experiment kindly undertaken by Mr Musk. And then when some results happen we decide.
Remember, development of the R-7 into the most reliable expendable booster took about 40 years and that with full backing of a Soviet Union.

Im rooting for Space X to fail partly because Starship is such a fantastically dumb idea, which isn't a surprise given the mental decline of Musk over the years.
To have it go to Mars, you have to have something like 20 refueling launches.
Raptor engines are the equivalent of taking a 2.0 inline 4 engine in a car and making it produce 1000 hp. Demonstrating one restart does nothing. You have to demonstrate reliable restart in a variety of conditions.
Vertical landings using engines to slow is inneficient. Sure, you reduce system complexity in not having wings or parachutes, but you gain it all back with things like engine restarts, and the need for high pressure ratio engines.
>I think as a culture we've lost the ability to compartmentalize
There is a limit to how bad a person can get, after which its probably worth for anything adjacent to him to fail so that he can't do the things he does. If Musk was aligned behind someone like George Bush, he would receive a fraction of the hate he does now. But at this point with Doge and his rallying behind a dictator (only to be hilariously dumped and fucked over with the BBB) is bad enough for all hate towards Space X to be justified. We would be better of as a society if people had more of a moral compass and actually did things like quit companies. Its not like there isn't competition with much more sane people at the wheel for Space X and Tesla.
So he's generally an ass to work for, got behind a politician you don't like, and fired a bunch of bureaucrats that probably shouldn't have been fired? Is that it? GWB started a completely unnecessary war, so if that's your example of OK in comparison, then I struggle to understand your standards.
> Vertical landings using engines to slow is inneficient. Sure, you reduce system complexity in not having wings or parachutes, but you gain it all back with things like engine restarts, and the need for high pressure ratio engines.
Well, the most cost effective rocket ever built uses this, but please do elaborate. What system do you propose that would be better?
> Is that it?
I was thinkin more along the lines of unconstitutionally cutting things like USAID thats going to actively result in more unnecessary deaths, personal vendetta against LBGT organizations in cutting those budgets, cutting IRS funding which is going to end up costing more ironically as there isn't enough staffing to pursue all the people using tax avoidance
Not to mention in general supporting someone and donating campaign funds who literally tried to coup the government, contributing to him being elected, and thus being responsible for everything that Trump is doing, from fucking up the economy further to playing wanna be dictator with ICE, all of which have long term repercussions.
In comparison to GWB, Trump is going much worse (especially if you want to compare deficit spending), and Musk has a direct hand in that.
>Well, the most cost effective rocket ever built uses this, but please do elaborate.
Cost effectiveness has nothing to do with engineering. For example, I can start a car company, fund it with my other business venture, and then sell cars for $50 and it would be the most cost effective car.
> cutting things like USAID thats going to actively result in more unnecessary deaths
That's bad IMO, but not helping people isn't remotely the same as starting a war that kills them (different if they were US citizens, but in this case they aren't).
> personal vendetta against LBGT organizations in cutting those budgets
I don't even have anything against these organizations, but I would cut their budgets to zero if I were in charge because funding them is none of the government's business.
> cutting IRS funding which is going to end up costing more ironically as there isn't enough staffing to pursue all the people using tax avoidance
This is dumb, but hardly a moral issue.
> In comparison to GWB, Trump is going much worse (especially if you want to compare deficit spending)
I 100% agree, but so was Biden, and I don't blame everyone who supported him either.
Fundamentally I don't blame Elon (or anyone else) for anything that Trump (or whoever they supported) has done that he didn't have a direct hand in e.g. DOGE. It's the nature of politics that you have to swallow a lot of things you don't like when you choose a side to support.
Look bro, we can spend arguing about details, but in reality, its pretty easy to put a nail in this: Trump tried to coup the government in 2020. And Elon supported this. This is not arguable. There is no fake media around this, you can read the lawsuit that resulted in the Supreme Court immunity ruling yourself.
You would have to prove with exceptional evidence that whatever Biden did or Kamala would have done would have been much worse.
Literally no other issue matters until you get over this bridge. Unless of course you are in support of a dictator and think his attempt to throw any legal process and the constitution out was justified, but at that point just say that instead of dancing around the issue.
>It's the nature of politics
No, at this point its solely in the moral/fabric of society territory.
> Starship is such a fantastically dumb idea
I'm sure there could be better rocket configurations than Starship - but so far Starship is better than other existing schemas. Starship is really good comparing to others - getting the cheapest kilogram to orbit cost in perspective.
That's assuming it can carry the payload envisioned, which seems iffy at this point.

Uh, SpaceX isn't funded by the government in the way you state.
It has contracts, but development costs are borne by SpaceX.
[Even worse than someone ranting like this is someone who then on top also self-replies!]
"But explosions aren't THAT bad"!!
Yeah, it just means that up until now, the chance of any astronaut crew surviving any trip anywhere is 0%. But hey, if some of the next tests don't end in an explosion, this maybe can be improved to 50/50 chance of death. Yeah, astronauts will buy that. After all, people also still buy Telsa's "Full Self Killing".
Darwin, please come to the rescue.

Uh, this is very unfair to SpaceX as a whole, which has had 0 fatalities so far on the ground and in the sky, after almost quarter of century of operation. This is a remarkably good record for spaceflight.
Contrast it to the Apollo project, which killed three astronauts even before the first flight (Grissom, White and Chaffee burnt to death during testing on land) and almost killed another three during mission 13.
Contrast it to the space shuttle with its 14 victims, and the first flight of the space shuttle was touch and go as well.
Contrast it to Boeing whose recent Starliner proved so problematic that they did not dare fly the astronauts back to Earth using the same ship and made them wait for a Dragon.
Contrast it to Scaled Composites, which never reached orbit, but three engineers were killed on the ground and one test pilot during a suborbital test flight.
Insinuating that SpaceX is a killing machine is absurd, when you look at their actual safety record and compare it to their competitors.
Too many things don't add up, for example: SpaceX, and friendly commentators, have framed this as a highly experimental test flight. The most visible aspect of that are the heatshield test tiles on various parts of the upper stage.
That kind of testing is understandable to a certain extent. But it doesn't make sense to ditch the rocket in the Indian Ocean once you've run those experiments, instead of catching it, and having all the parts available to study.
The ground equipment is the longest lead-time item for future flights. If you accidentally blow that up, it sets the program back months.
How much would it cost them to catch it, though? Not just in money, but time. How do you know it doesn't make sense?
I don’t think they are letting go of these rockets; they are definitely being retrieved back. Otherwise, rival countries like China will end up retrieving them.
The tower is more expensive than the rocket. The old tower is sketchy and quite flawed, and the new tower is not complete yet.
