Oh no they lost the ship after the booster landed! Seems like they lost an engine, then I saw fire around the rear flap hinges in the last images before they cut out, and then the telemetry showed more engines shutting down until it froze. During ascent I also noticed a panel near the front fins that seemed to be loose and flapping. Probably not related but who knows. Edit: Here's a video of the aftermath. Strangely…

I believe it's pretty hard to have a fire at that altitude. You need a leak of both methane and oxygen, and an ignition source.

I wonder if perhaps one of the engines split open and the exhaust wasn't going into the engine bell?

Telemetry showed them lose engines one at a time, which isn’t a great sign.

I think that’s the normal shutdown order to reduce shock, the timing was exactly the expected second stage shutoff time if I understood it correctly.

Incorrect it failed asymmetricaly in such a way that would pitch the vehicle in circles. Normally the sea level raptors are turned off and the space raptors are slowly brought down together.

The flight paths are planned specifically so any potential debris has a high chance of landing in the ocean. If it actually exploded (either on its own or because the flight-termination system kicked in) most of it should burn up on reentry though.

What happens if it doesn't explode and they just lost control over it? I'm mostly curios of the risks at that altitude.

There's an autonomous flight termination system which triggers if it strays outside the planned flight corridor; any debris that survives reentry should then land in the advertised safety zone.

Looks like second stage broke up over Caribbean, videos of the debris (as seen from ground): https://x.com/deankolson87/status/1880026759133032662?t=HdHF... https://x.com/realcamtem/status/1880026604472266800 https://x.com/adavenport354/status/1880026262254809115 Moment of the breakup: https://www.instagram.com/reel/DE52_hVSeQz/

What a strangely beautiful sight. While I was excited to see ship land, I'm also happy I get to see videos of this!

Great observation. I also do this. :-)

That "landing" (is it still considered a landing if it's chopsticked a few meters before it touches the ground?) is so unnatural it almost looks fake. So big and unimaginable that it feels like watching fx on a movie! The close-up camera right after was interesting, I thought it captured on the grid fins, but it looks like there are two small purpose-built knobs for that. The times we live in!

You have perfectly described the feeling I had regarding the first belly flop demo (at least I think it was the first one?)

If it doesn't explode it might be light enough to survive reentry, after sailing on for a short while. In that case a large chunk of metal will come down either off the coast of South Africa or if continues on in its orbit potentially off the coast of Australia.

[1] has the planned flight path, as well as the impact zones.
