Successful Raptor on-orbit relight demo! That should clear the next flight to go to orbit and deploy operational satellites! Big milestone for the program. And the ship landing was so soft it didn't even explode! That's never happened before. And it's still connected to Starlink too. The ship's cameras are still working underwater! I wonder if they will be able to recover it intact? We're getting some great views of…

They have a much biglier support vessel this time, almost 300ft long IIRC. So maybe they can recover it?

It’s interesting the cognitive dissonance this brings out in me. As much as I think Musk carries a fairly reprehensible aura, I would still like to see SpaceX succeed. Space has a funny, transcendent way of inspiring us.

Actual, literal Nazis got us to the Moon and frankly no one cared. Not then, not now. Try separating politics from the advancement of humanity, you'll feel better.

Yup. Some of the Youtubers (like NASA Spaceflight) had video of it hitting the water pretty fast and hard. That said, this is the only test failure so far. I'm cautiously hopeful they get Ship to touch down. (it will explode after it does because of physics but stepping lightly onto the ocean will be a win)

>it will explode after it does because of physics Is this just a fancy way of saying lightweight fragile aerospace tube with hot stuff all over the outside and flammable stuff on the inside will not respond well to falling on it's side or is there some other thing going on here I don't know about.

I guess they also failed to explode it

I am pretty unconvinced that any of the past explosions of starship used that feature. It’s very convenient to have an “explode” button so you can say all of your rocket detonations were intentional, but they are often leaking fuel or dropping chunks before they explode.

This was a great flight, though.

Sort of? Everything is weight. And since it isn't a design feature to lay down in water there isn't any weight budget for making that modality survivable? So typically when it falls (and this thing is really tall) the interior tanks detach from their mounts and hit the inside walls and rupture. The skin is still hot, oxygen and remaining fuel mix and it goes boom. This time we had fires but no boom. I look forward to hearing what was different.

They juiced the engines up big time with the Raptor 3 upgrade. The rest of the stack is leaner and meaner too, but engines are the single biggest upgrade. It's why they have plans to elongate the stack further. If they have this much TWR to go around at liftoff, they can afford to cash in that extra thrust to pack more fuel.

> they have plans to elongate the stack further Elon gate the stack.

Pun employed intentionally.

i don't think so - the ascent looked good. i don't think they need to put the ship on another suborbital trajectory because the booster landing burn failed. also, i don't think this impacts prop transfer or ship catch - both are separate problems.

I think this is technically true but that they want a seamless suborbital flight (like the last two for the Block 2) before they move forward on those other goals.

Why wouldn’t they only care about seamless ship flights, to get some value out of the launches, while they’re still learning and figuring out how to light booster?
