"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.
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.
It's way harder to do it the first time.
raptor engines are designed to be cost efficient, as is the rolled steel? that is used for the fuselage
As with any manufactured item, high volume and iterative design improves the production process and finished product.
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.
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.
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.
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.
Nailing it would be without the things above.
I'm surprised they didn't take less risks just to avoid a narrative of failure.
It's privately own, might as well learn as much as possible with each dollar spent.
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.
The biggest can't-miss milestone was the flawless engine restart. That gives them the go-ahead to hit orbit on the next flight.
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.
In SRE, we have chaos engineering so I'm wondering if it's the same concept.
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.
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.
I was very surprised that that flap still held up during the stress testing on atmospheric re-entry.
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.
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.
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.
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.
Advancing human scientific progress, but at what cost?
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.
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.
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.
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?
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?
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.
Please tell us which culture war topics he’s anti-science on.
As far as Trump (and the administration in general) being anti-science. I really don't think I need to list examples of this.
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.
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.

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.
fluoridation•24m ago
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.
dylan604•5m ago
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

> 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.
nashashmi•1h ago
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

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 cost.
wat10000•10m ago
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.

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.

I bet it will get to the moon cheaper, too, and the Muskonauts will use less expensive lenses than Hasselblads to take photos.
fluoridation•57m ago
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.
stetrain•53m ago
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.
fluoridation•42m ago
> 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.
DarmokJalad1701•32m ago
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.

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.

And it's totally valid for you to have that opinion. But it's your opinion, not "the consensus."
ajmurmann•18m ago
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.
