The test is essentially a success at this point. Starship can take payload to orbit and open/close the payload doors. The remaining things are icing on the cake. They can refine re-usability while flying payloads.

I wouldn’t classify the re-entry survival problem as icing. But otherwise, I agree with you.

They can launch payloads that bring in revenue while working on that problem. There is a good chance they put a bunch of Starlinks on the next flight.

I was surprised that during the initial ascent footage from the fin-cam, you can see that the grid fins are out. Do they not fold back on ascent? Or possibly drag on one side to arc over? Just seems weird to have your “drag device” deployed during ascent.

They're control surfaces, they help keep the pointy end up and the flamey end down

They have a great pipeline for building ships. They want reusability, but for near-term needs like deploying bigger Starlink satellites and their moon lander contract they could probably power through without reentry survival. It would be expensive, but unlike in-orbit refueling not really mission critical

My understanding is that Starship is financially comparable to Falcon 9 on a per-payload basis even if fully expended.

To be fair the capsule caught fire in a ground test once with three lives lost (Apollo 1) and the command module had an explosion in space once (Apollo 13) with no loss of life but it was a close thing. I do agree with your larger point though. SpaceX just feels so much less impressive then previous major rockets, and that's only reinforced when they try and celebrate minor milestones like its supposed to be the grea…

The apollo 1 capsule was on a Saturn IIB, not a Saturn V.

They fold in/out on Falcon 9, but for the starship booster the decided it's not worth it. The extra weight and complexity to fold them in/out doesn't provide enough of a benefit. Elon talked about it a couple of years back on one of Everyday Astronaut's videos.

That's impressive revisionism. Where's the Soviet reusable launch vehicle that is half the price, is able to reuse even one stage and takes less than a month to refurbish?

Nevermind

Interesting. What is this amazing Russian rocket that can put 200 metric tons in Low Earth Orbit while being expendable?

Yeah, breaking up in-air during re-entry (at 65 km going by last telemetry) seems like a potential big issue to fix.

OP's point is that the tests become a bit cheaper and a bit easier to get licenses for since they can get to orbit and can deploy Starlinks. The reentry problems of course have to be fixed, but the FAA mishap investigation will involve fewer delays, just like how Falcon 9 was able to keep flying, attempting landings without having to wait for a mishap investigation to finish every time a landing failed.

Technically its suborbital

Isn't orbit above 125 miles (200km)?

It's in space (above the Kármán line), but not in orbit. Orbit implies it has the velocity for staying in space, which isn't the intention here. If anything goes wrong they want to be able to not leave junk in orbit

Technically it's a transatmospheric orbit. That is, an orbit such that it'd stay up there if the atmosphere were not present. The difference between this and full orbit is just a few seconds longer burn, so it's a difference with little meaning in terms of proving out the ability to reach orbit.

I don't believe that's the case—see the math in my sibling comment.

Sounds like the Russians could clean up in space-launch market. Why aren't they?
