SpaceX catches the Starship to end Flight 15 (x.com)

Starship is, essentially, Space Shuttle done right: fully reusable booster without solid boosters (avoids Challenger disaster) and orbiter stacked on top instead of on the side (avoid Columbia disaster).

The original designs for the Space Shuttle had the booster (with wings!) return to the launch site, but the cost for two new crewed vehicles was too large, so they scaled it back to the compromised version.

Even more revolutionary, compared to Shuttle, Starship is built on an assembly line. They can build a booster ever 4 weeks and a ship every 2 weeks.

The future we were promised in the 1970s is about to become real.

If the heat shield holds up then this changes everything. Next step is double catch and re-flying the same ships and catching again, then payloads to orbit become significantly cheaper opening a new era in space flight.

modeless an hour ago

Yeah, I'm eagerly awaiting results from inspection of the heat shield (which hopefully they will disclose). Reflight without refurbishment is the last goal they need to hit before the system can be considered a success. After that, optimizing for increased payload and nailing reliability will be the things to work on. And of course orbital refueling for HLS.

ACCount39 19 minutes ago

They already recovered a ship from that one time they accidentally landed one in the ocean. SpaceX got to have a lot of heatshield endurance data by now.

proxyscore an hour ago

This changes nothing, in space fuel transfer between ships is the make it or break it.

modeless an hour ago

Fuel transfer seems like a trivial problem next to the reusable heat shield. And even if for some weird reason it never works, the program could likely pay for itself just launching Starlink/Starshield with full reuse.

I'm still not really convinced this is better than a space-shuttle style landing.

Seems like the same design principles that goes into Starship could create a version with more aerodynamic surface.

Huge congratulations to the engineering team on this one! It's been quite interesting to watch the evolution of Starship. Had they put another couple of tonnes of propellant and oxidizer on the Booster they might have caught both of them. It is still unclear to me what the final mass fraction to orbit will work out to be, but something that is 100% re-usable is better than something 60% reusable[1].

[1] Estimate of Falcon 9's booster + fairings being 60% (by cost, not by mass) of the launch package.

It looks like they delivered 50 tons today. Even if it stays this way, it will still reduce price to orbit significantly.

I know engineering is about expediency, and price, but I’m still bummed that we aren’t getting ships with landing gear in this or likely the next generation of rockets either.

Seems that the heavier the rocket the more ground clearance to need to self-land, and so you can’t scale up the dragon’s landing system. I don’t think there’s anywhere near enough weight to shave off of the next rocket or enough specific impulse to add to bring the size back down.

Starship HLS has landing gear. For Earth landings everything is so marginal that the weight penalty of landing gear is too high.

I unfortunately agree. Years ago I realized the Mars talk was just talk when I noticed that Musk and SpaceX were not funding any of the other stuff you’d need to fund if you wanted to “make life multiplanetary.”

Continuing to iterate on self contained biospheres and long term closed cycle life support? (Not a solved problem!) Working on construction techniques for the Moon or Mars? Studies on the dose response curve for gravity, like sponsoring a spin lab for the ISS to at least see if mice can reproduce in 0.3g? Self contained industrial infrastructure leaning heavily on 3D printers? Psychological research on the best way to build interiors and run social units?

Musk could personally fund all of that with little impact on his net worth.

It’s also decades of work. Some of what I listed is harder than the rockets. Better get started if you want to have a settlement on Mars this century.

Nope. Nothing. Just rockets, the a satellite network that is clearly “dual use.” Then Trump 2.0 and lots of “golden dome” (Star Wars 2.0) talk.

It’s not to go to Mars.

I love space and I hugely admire the engineering achievement, but it’s disappointing to learn for this and many other reasons that the people behind it were not the visionaries they pretended to be. They’re just more territorial apes obsessed with ape tribal stuff like race and nationalism and fighting over dirt at the bottom of a gravity well. Small minds with big toys.

bluescrn an hour ago

It was extremely cool 45+ years ago. But the space race ended, and while government-funded space programs did some fantastic work beyond that (space telescopes and Mars landers), it took capitalism to develop the resuable rocket, then scale it up to Starship proportions.

Onavo an hour ago

I had to read the comment below (from u/modeless) before I realized by landing gear you meant the upright ones. I thought you wanted it to land sideways like a plane. (Arguably doable, though the control systems might add a lot more weight)

hinkley an hour ago

The problem with space planes is they are terrible planes, terrible rockets, and feed the egos of pilots.

To be fair to NASA and the astronauts, NASA needed humans who behave like military test pilots. In physiology, in reaction time, in crisis management, in following chain of command. And the armed forces were willing to give them access to known quantities.

We didn’t know how control systems would evolve over the next three decades, but the pilots wanted to pilot, and did not trust the control systems. And the irony of it all is that the Space Race was a proxy war for nuclear armament, so control systems needed to be made autonomous anyway.

Better control systems, wider telemetry, and not worrying about incinerating employees let current generation rocketry iterate faster, and do more fucking around and finding out. We found out twice with the shuttle and it killed the program.

It’s curious how much the upper stage now resembles a space shuttle on a ballistic trajectory instead of a glide angle. Very different landing strategies for those two modes of descent…

And even if you hate Elon and all his businesses, this knowledge will proliferate. Either by talent movement / osmosis, by espionage or just being inspired ("if they can do it, maybe we have a chance as well").

Within a decade the average cost to LEO will drop 20x-50x and if you're not recovering both of your stages, you don't exist.

At the last moment the exhaust turned green. That's consistent with the fuel running out, the engines running oxygen rich, and subsequently "engine rich". So I would put my money on actually running out vs a measurement error.

> damn, I just don't see what we're trying to achieve when there are so many issues we can't even figure out on earth

Earth issues are mostly coordination problems. Space issues are technological problems. Elon Musk has been very successful at solving technological problems: electric vehicles, space flight, mind-machine interfaces.

It makes sense that people like him who can solve technological problems point their attention and substantial agency to the things that their unique skills place them in a position to solve.

The Elon Musk of coordination does not currently exist. One must imagine that the kind of person or school of people who instituted NATO and the US-Japan MDA and turned our one-time enemies into our staunchest allies were people of such caliber but there’s no one I know today who qualifies for that.

Musk definitely has mastered firm-level coordination but clearly national coordination (let alone international coordination) is a problem beyond even him. His teams nearly religiously point the same way, and they have achieved wonders. It is truly remarkable what these people have done. Good for them, and I’m glad to see them at it!

It's difficult to underline how huge this is. This marks the first time in the history of rocketry that the upper stage of a rocket has returned home from orbit to a safe, upright landing.

(And to preempt the obvious objection: yes, maybe you can call the Space Shuttle an "upper stage of a rocket" if you squint hard enough, but it didn't do upright landings, its external tank was not reusable and even the Shuttle itself was effectively rebuilt from scratch at exorbitant cost each time.)

It's sad to see a lot of media missing the point, eg as I type this BBC is reporting this as "SpaceX successfully catches part of Starship rocket on its return to Earth".

Edit: corrected to note that the SRBs were reusable, but the ET was not.

mmustapic 2 hours ago

Notably, they were reusable! Sure, they had to refurbish them, same with the shuttle’s main engines. The only thing they threw away was the external tank which didn’t have any engines.

Whatever you call it, the Shuttle Orbiter wasn’t a complete stage in any case. It needed the external tank, which was never recovered.

SpaceX has now demonstrated all the pieces of a fully reusable launcher. Next comes putting them all together in the same flight, and hopefully demonstrating that the flights can become frequent and cheap. There’s no guarantee of that, but it’s looking good.

palata 2 hours ago

> yes, maybe you can call the Space Shuttle an "upper stage of a rocket" if you squint hard enough

Why wouldn't it count? It is not the first time in the history of rocketry that the part that is not the boosters returns home intact.

Sure, you can say "it's the first time in the history of rocketry that it lands upright", but you could also say "it's the first time in the history of rocketry that it is not white".

If you want to say how huge this is, tell me how different it is from landing the boosters. Because from the outside it sure as hell looks very similar.

motionlessveloc 2 hours ago

The Space Shuttle has four parts, namely the Orbiter, the External Tank, and the two SRBs. Only the Orbiter is reusable and actually lands, the rest are jettisoned in flight. (SRBs are recovered, the ET is not.) However, the Orbiter is completely incapable of flight without the other three, so it's not a rocket stage on its own, just part of one.

As for why it's harder to catch Starship than Super Heavy, where do I begin:

* Super Heavy is suborbital, its maximum velocity is far, far less than Starship.

* Super Heavy returns upright. The Starship does the famous but aerodynamically very complex "belly flop" to reduce speed.

* Super Heavy only has two static fins to guide it. Starship has four actively controlled fins that need to survive the extreme forces of launch and re-entry.

Do you want more cool stuff like James Webb in orbit? Fully reusable huge rockets like Starship is how you get them there.

Also, remember how JWST had to do that incredibly complex and fiddly in-orbit expansion and alignment to fit together the mirror after launch? If Starship had been available at the time, this would have been far easier, since Starship has twice the diameter (four times the area) of the Ariane rocket they used to launch it.

fedpost 2 hours ago

That's...the point. You can hire commercial welders to work on the ground side and build everything out once, cheaply.

The issue with the shuttle era was that they needed huge teams of specialized technicians to refurbish the insanely complex orbiter after every mission.

If we ever get sufficiently improved materials science for heat shields and engines there's still always a possibility of returning to the SSTO space plane concept. That would allow a more austere launch and recovery environment, but given current limitations this is the local maxima.

This is exactly the most impressive feat of engineering I have ever seen.

Only catching both the booster and the rocket would top this one. But the rocket only being caught is still impressive regardless.

SpaceX below $1T is criminally undervalued.

SpaceX below $1T is criminally undervalued.

Launch itself isn't super profitable and doesn't have a very big TAM, especially if you carefully treat the TAM as a present value and discount future cash flows. Also, at least by my personal guesswork, Starlink alone shouldn't get close to a $1 trillion valuation. It seems like the current valuation is based on people's guesses about the likelihood that space data centers pan out in a big way.

The Starship program is one of - if not the - biggest risks here. Making starship work could bring the launch cost down far enough to derisk that whole program, and today just made it a lot less risky

dylan604 42 minutes ago

We've seen the booster landing/catch before, but seeing the ship do it with the belly flop definitely looked cooler to me. I still remember the awe of watching two boosters land at the same time after a heavy launch. Watching the transition from bellyflop to landing gave me the same awe and being impressed.

Why is Space-X undervalued because they can catch a rocketship?

You do understand that a company needs to have a business case equivilient to its valuation right?

Going to Moon only costs money, going to Mars only costs money.

Our whole planet sends 1000-2000t of payload into space, most of it is now starlink.

The market values SpaceX over multiple areas of the business and their future plans and it isn't just this event which they have proven to accomplish.

> You do understand that a company needs to have a business case equivilient to its valuation right?

Nope. That is not how this works nor how investors see it. It is about their total addressable market (TAM) which SpaceX can capture over everyone else. So here are some more further questions:

1) Who is paying SpaceX for the compute that they have?

2) How quick is SpaceX building their data centers to support their customers?

3) How many people use Starlink as their primary internet provider?

You understand that almost all of where SpaceX businesses can expand into those areas and grow into that valuation and higher?

> Our whole planet sends 1000-2000t of payload into space, most of it is now starlink.

Your point is?

So who else can catch and reuse a rocketship to frequently deploy satellites into space in a very short period of time? (Don't say Blue Origin.)

Well, both booster and ship catches have been demonstrated now.

Did they catch both of them in this mission?

It was meant to be a dual catch of the booster and the rocketship and only the rocketship itself was caught.

Catching both of them in another mission would top this one.

Nice! I wonder how the engineering involved here compares to the engineering behind manufacturing TSMC chips (including ASML machines, Zeiss optics etc.). Which is harder?

As it seems building rockets has historically been a capital intensive business with low profits and limited demand, so there just wasn't much competition in the space industry.

Many countries are capable of space flight & deploying satellites.

Only a few companies in the world can manage the top-tier fab processes for modern chips.

Only one company in the world has successfully caught a rocket. *Edit: 2!

It's hard to directly compare, safe to say they are 2 of the pinnacle examples of modern human engineering.

Reusable stages is very neat, but seems a little crazy to pay the tyranny of the rocket equation twice. I heard one person say that carrying fuel to land over the whole flight means it takes 23x more launches to get an equivalent payload to orbit.

Using modern technology, couldn't disposable first stages be produced much more cheaply than during the space race?

How much of modern manufacturing disposable booster's cost would be fuel vs metal?

blackenedgem 2 hours ago

It's not paying it twice. The rocket equation is about the ratio of the wet and dry mass, so for an expendable rocket you're always limited by the fact that there's an upper stage (and for the second stage the payload etc).

This is why SpaceX cares more about TWR for their engines than traditional rockets did. It goes from making a negligible difference to a huge component of how much fuel they need to keep for landing.

grey-area 2 hours ago

This seems a little confused.

The 23x more launches figure comes from HLS (Nasa sponsored mission to the moon). They may well change the configuration of that anyway, but if you want to refuel in orbit, that's what it costs. It's hard to get fuel to orbit (or any sort of payload). Previous Moon missions haven't refueled anything, but they couldn't return anything heavy from the moon's surface, the vehicle got smaller and smaller as it went and many parts were left behind, so it's not comparable. You can be sure if it's cheaper to somehow do this mission with expendable boosters, they'll think about doing that.

On a normal mission just to earth orbit, there is one booster and one starship, and reusing the booster is more a question of why not save some money for a little more propellant use? The reususable booster doesn't contribute much extra weight, it uses little propellant for boostback and landing.

The booster also doesn't go all the way and you need a booster if you're going to reach orbit (due to that equation), so it doesn't take much to make it reusable. So all in all, why not make it reusable if you can? What would you save from using expendable ones?

This claim doesn't make sense to me, you need most of the fuel to escape gravity. Coming back is almost free.

luke5441 2 hours ago

It costs less, but it is not free. The stages need to be designed to come back and that adds weight. Additionally you need some fuel, it is not all air breaking. And every bit of weight is really bad, because of the rocket equation.

Without internal figures no one can say what is ultimately financially better. Especially now that the development is a sunken cost.

If the fuel (+ oxidizer) ends up costing as much as 1% of the cost of launching a conventional single-use rocket then the people behind it will be very happy. That means that their rocket (+ cost of ground facilities + all the people prepping the rocket and monitoring the launch) is very cheap.

The fuel (+ oxidizer) is basically free compared to all the other costs.

GenerocUsername 2 hours ago

Those numbers don't make sense.

It doesn't take the same amount of fuel to land as it does to lift.

Speaking as a Kerbal Space program playing, internet commentor, It's probably <1% of the fuel to briefly counteract terminal velocity as it is to lift off and reach space.

consensus1 2 hours ago

That 23x number is trivially refuted simply by looking at the fact that this flight delivered 52 tons of cargo to orbit. Could a similarly sized expendable rocket like the Saturn V deliver 1196 tons?

ivewonyoung 2 hours ago

How is it twice? Braking on the way down doesn't take nearly as much fuel as lift off so the "tyranny of the rocket equation" should be paid only once.

inglor_cz 2 hours ago

"I heard one person say that carrying fuel to land over the whole flight means it takes 23x more launches to get an equivalent payload to orbit."

I don't think that this is the case when using the atmosphere to shed most of your velocity, which is what we do when landing on Earth. Propulsive braking would be another story, but you can avoid that on bodies that do have some atmosphere. In our proximity, only the Moon and Mercury would need propulsive braking, but Moon's gravity is low and Mercury is hard to visit anyway.

That said, once you use the atmosphere to cushion what is basically a fall, the weight of the necessary heat shield comes to the equation too.

jiggawatts 2 hours ago

They use the atmosphere to brake, not fuel.

That's like saying we shouldn't reuse airplanes after one flight because you'd have to fly it 23 times to have it pay for that reuse.

That's still 1000x cheaper than... building a new airplane every flight.

And anyway those numbers area about moon missions, not low earth orbit.

We don't have to look past it. Musk said it failed because engine underperformance caused too little fuel margin. He added that they have upgrades due on future flights.

If they ran out of fuel with 50 tons of payload it certainly begs the question of whether they will get to the goal of 100 tons of payload even with upgrades.

They also had engine fail on boostback. Reliability has been a persistent problem, they'll have to fix it for refueling and manned operations.

Booster catch has been done as has booster re-flight. The only remaining part of the full functionality that has not been proven out is ship reuse.
