Any idea how to rewatch the twitch stream from Chris G and Dasz ?

I just watched the landing in SpaceX stream, now in the coast phase I wanted to switch to their stream and rewatch the landing from their vantage point, but twitch doesn't seem to allow rewinding in a live stream the way youtube does.

Is there an alternate URL for that stream that can do that?

Do we know anything about the stage 2 second burn post-cutoff sep burns and fuel purge times? Folks in the predawn western Indian Ocean might get a great UFO sighting!

Can only second what mlindner said: SpaceX makes this look ridiculously easy!

- They are doing stuff that just a few years ago was never even contemplated by any other aerospace company... No, strike that. That wasn't contemplated by ANYbody. And they make it look like a walk in the park.

I mean..... - landing three boosters within 11 minutes of lift-off.... :-O

If they can pull off this craziness... - What other craziness can they pull off as well? Here's looking at you, Boca Chica!

Heard over the countdown net "Load limiting shutdown." and a while later "2nd load-limiting shutdown" before BECO, looks like they are shutting down booster engines to limit G-loads prior to BECO-proper.

I thought I saw a big plume of dark-looking smoke several seconds prior to booster sep in the Kerbal Space Academy/NSF live feed and I immediately thought an engine blew. Guess it was just the 2nd shutdown transient.

EDIT: Reviewing it again now and yeah, it was just a stream glitch, but damn it sure looked black and ugly for a second!

Uh, like they got rewarded from NASA with a mission to an asteroid?!

Numba 2.... build the Starship! Use and re-use.

NASA can only look in AWE!

They mentioned in the stream they would be putting it up on the NSF YouTube channel.

Congratulations for capping off such an extraordinary day in space with a resounding accross-the-board success of FH! THat was thrilling and a pleasure to watch!

John's really doing a great job inserting technical info and addressing what are likely very frequent questions (e.g., the oxygen "snow" on the vent).

He's really improved as a commentator over the years, hope he stays around for a while.

Was anyone else having the SpaceX/Youtube feed crash as often as the Soviet Mars program?

I don't think I previously understood just how far out the barge is for a FH launch.

This one is farther out than any barge for a downrange recovery before, by a couple hundred km.

I noticed that my SpaceX feed on YouTube was about 30 seconds behind our NSF guys!

Outstanding and congrats, SpaceX. (adopts a Jeremy Clarkson impersonation) "What a machiiiinnee!!"

Yep - and when it wasn't crashed, I felt like Mr. Magoo 'cause it downgraded to 240p.
