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.

Not quite: the apogee burn they had planned didn't happen (no word as to why yet), so the ship didn't technically demonstrate the capability reach orbit. It came back down in the Indian ocean on its original suborbital trajectory, essentially like an ICBM.

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.

Fuel transfer with what? That would require things like docking

Transfer internally between tanks in the bottom and top of the ship. This was one of the planned tests, I have not heard whether it was accomplished though.

There was a callout saying that it was successful.

Edit: On the other hand tweets from Gwynne suggest that they still need to review the data to see if it was a success.

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

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

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?

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

The point they were trying to make is that getting up is MVP, getting back down can be figured out later

Nevermind

That is a matter of the trajectory they chose on purpose for this test flight. A different flight profile would have given them a perigee above the atmosphere (rather than -50 km)

Parent's (correct) point is that it isn't a matter of the ascent trajectory. They can't leave the Starship up in orbit, and where it reenters needs to be controlled.

There's a fake SpaceX YouTube account that looks official because they included videos from the real channel in playlists to get verification ticks & have managed to harvest thousands of subscribers. YT's interface is a bit dumb for including the verification ticks in that use-case.

YT's interface fights negative feedback harder than a spoiled toddler. Hiding downvotes, squirreling the "block channel" feature into a dot menu, breaking it completely on recommended pages, and then breaking search pages... it's almost like they don't want to fight spam.

They're in the ads business - watched hours = money.

Why remove spam and clickbait when it means less money? Youtube is the stereotype of post-hype company that is just milking its users to increase their bottom line, driving the entire product to a slow death.
