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.

Well, the second stage definitely needs to survive re-entry if it wants to carry passengers. But it seems to work as-is for orbital cargo.

That’s a Twitter embed on the SpaceX website. It’s still streaming from Twitter.

but no Twit...er, X account required

I will be deep in the cold cold ground before I recognize Twitter's new name

So FAA cleared SpaceX and then within a few days they completed their launch pretty successfully by all accounts. So does that mean SpaceX could have launched a while back with no issues and were just waiting on the FAA? Did the FAA literally just slow down progress? Not a good look on the FAA, they should just let SpaceX do what it does at the speed they want. If they cannot add any value to this engagement, the lea…

Doesn't appear so, no. https://en.wikipedia.org/wiki/SpaceX_Starship_integrated_fli...

> On March 5, 2024, SpaceX announced that they were targeting a launch date of March 14, 2024, pending regulatory approval. On March 13, 2024, the FAA granted the launch license for IFT-3.

Here's a fun thought, how many Starship launches would it take to put the equivalent mass of the ISS up in the same orbit?

How many launches are required to land on the Moon?

I'm still in awe that I got to watch a reentry live stream just now. I wish I could tell my child self what wonders were in store. Watching humanity progress in real time is amazing.

Kids. I got to watch a moon landing live. (Not a stream, and crummy resolution, but still...) [Edit: I meant to be talking smack a bit, but don't let me ruin your enjoyment of the really amazing things that are happening now.]

Yeah, it's pretty awesome to watch "the first" of something! I wasn't born early enough to watch the moon landing, but I did watch the livestream of the first successful landing of a Falcon 9. Watching that bit of science fiction turn into reality was one of the more memorable moments of my life.

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

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

bright side: booster made it all the way to splashdown

> Yeah, breaking up in-air during re-entry (at 65 km going by last telemetry) seems like a potential big issue to fix. That's what pretty much every non-SpaceX rocket does today with very few exceptions.

And indeed every spacex rocket. Starship is the second stage -- and a second stage on a F9 burns up in the atmosphere just as much as Starship from IFT3 did.

The big things to fix seem to be

1) The roll rates for starship (which prevented the inflight relighting test)

2) The Booster relights, which didn't have enough lighting to soft land.

Both of those feel like minor problems.

I'm amazed that the propellant transfer demo seems to have worked first time, and of course they managed to get the tihng up there in the first place.

The reusability of the Starship part of the system is a much bigger unknown, but that doesn't seem to be necessary for the next launch.

Wouldn't surprise me if the next try is by the end of April

Passenger rating isn't even in the cards for Starship for a long time. You ride to LEO on a Falcon-9 with a proven track record for the foreseeable future.

The ISS weighs ~420 metric tons. That is 2-3 expendable launches or 3-4 reusable ones.

Jesus Christ, that really puts it into perspective what a game changer starship is

Not just the capacity per launch but the cost per launch also.

those plasma views when starship was coming into atmosphere were absolutely mind blowing. it makes a lot of sense to use starlink for this, but it never ever crossed my mind.

The booster puncturing spheres of clouds on a way back was awesome also.

That was my highlight of the test: live video of the biggest rocket booster hitting the ocean at 1000km/h.
