Now that I'm here, if this launch works, it will be the first I've seen that did work. I've literally not seen it work ever during a live broadcast. Every damn time I'm here to see it, something blows up or it is rescheduled. I want to see it land on one of the drones.

His engines are ready, clamps weak, fuel is heavy
There's icing on his panels already, Elon's spaghetti
He's nervous, but on the surface he looks calm and ready to lift off
But he keeps on forgetting, when he'll touch down
The launch pad goes so loud
He opens his valves, but the thrust won't come out
He's choking how, ULA's joking now
The clock's run out, time's up, over, blaow!
Snap back to reality. Oh, there pulls gravity
Oh, there goes Falcon, he choked
He's so bad, but he won't give up that
Easy, no
He won't orbit, he knows his whole back's to these loads
It don't matter, he'll cope
He knows that but he's broke

When he goes back to his mobile pad, that's when it's

because he basically just says common sense things about why most "worldchanging" techs will not be so, and since most of those things are either fake (ala meme drive) or otherwise don't live up to the hype he seems smart because he stated surface level criticisms in a cogent way.

did they have a robo voice countdown?

>> No.9228529

I think that's basically his question.

Obviously there are a few options. It can either hibernate, and just stay in the orbit it had achieved until eventually atmospheric drag causes it to re-enter in a bunch of decades. It could do a short retrograde burn at the apoapsis so that it will re-enter and burn up. Or it could try to reach a graveyard orbit.

Chances are that it doesn't have fuel for the graveyard orbit burn, or else it would boost the payload into a higher orbit, so the question is does it just sit in the orbit until it re-enters naturally or does it de-orbit itself?

>> No.9228530

I'm pretty sure I haven't seen the first stage creating plasma on re-entry before, at least not a landing re-entry.

It was still going like 7000km/s when the re-entry burn finished.

>> No.9228539

I'll amend.

It was going 6300km/h (the km/s was a huge mistake) at the end of the re-entry burn.

In comparison on the OTV launch at the end of the re-entry burn it was going at 2600km/h.

Looking back at the SES-10 launch, they don't have first stage telemetry when the re-entry is happening but the grid fins get pretty toasty before video cuts out, losing practically all of their white paint. I don't see any plasma though.

Why would m/s mean mph? That doesn't make any sense at all.

>> No.9228791

Well I found the answer.

Basically, LEO is usually deorbited, because they have the fuel remaining and there is less risk if anything catastrophic happens when they fire up the deorbit burn.

For GTO it is usually left to deorbit on its own. With a periapsis of 200~300km it takes around 6 months to reenter. If it were to blow up trying a deorbit burn it would leave a lot of debris flying through the GTO window so they don't risk it.

If they launch to something like L1 then it goes into a solar orbit and is left there.
