I thought that gimbaling shot in the tweet from 44 minutes ago was current for a second but no. Pretty sure that's on a sub orbital mount.

It is clearly the OLM. Note the pillar in the back and the piping up top

Made my @NBCNightlyNews debut live from the Starship pad, to talk about one of the most significant rocket launches of the 21st century so far: https://www.nbcnews.com/nightly-news/video/spacex-s-starship-to-make-its-first-orbital-test-flight-170442821902

It today the final day of the Before Starship Era? Because when this begins to work, it changes humanity’s relationship to the sky forever. Mass, volume, and cost have been ruthless adversaries to spaceflight. What happens when we start to beat them back? 🚀

Flights into Brownsville recently as Starship is posed to launch tomorrow. Elon Musk, Antonio Gracias (Fmr. Director of Tesla), and Yusaku Mazawa. Flying in from Tokyo, ~11 hour trip.

When the laser display folks like that we're enjoying their show, pop into chat, say "watch this,"- and put NSF on the Megabay for a few seconds..... 😎

Good luck @SpaceX and @elonmusk 🍀🚀

re. The timing 2

Launch is now 8am at the earliest.
I guess Prop Load Go Poll is now 6am
Spacex video will begin at 7:15am
Starship splashdown is now 9:30am earliest

But is the launch window still 150 minutes or has it reduced to 90 minutes?

P.S. Can the orbit posts not simply be deleted by the mods when they appear?

Musk predictably downplaying expectations of a successful launch, while emphasizing the long-haul process:

Huge line of vehicles at Isla Blanca Beach Park gate at 3am. Gate opens at 4am, Starship launch at 8am 🚀

Some guy from TimDodd/EDA's team asked Elon why no soft landing attempt for S24 at the end. Elon's reply seemed to say that he had such low expectations that S24 would achieve its full mission trajectory all the way, so that he didn't really care about attempting a soft landing (he also mentioned the inability to fit S24 with legs and ballast for tailsitter landing)

Just listened to Musk's Starship Twitter Spaces discussion.

He mentioned the hundreds of changes from Booster 7 to Booster 9 including electric thrust vectoring, new heat shield, etc.

It occurred to me that that magnitude of change, to a rocket system that has already been designed and built, would take an Old Space company literally YEARS to plan, build, component test, integrate, integration test, etc etc. Really highlights the Move Fast And Break Things advantage.

Regarding the booster return...

there has been no mention of an entry burn.... Is there not a risk of damage to the engines coming in hot without reducing speed. Falcon regulary knocks off 2000-3000 kph at entry burn.

any thoughts?

I understand that staging happens earlier, at lower speed. Also the steel can handle heat better

It wasn't the steel i was worried about, rather the engines which take the brunt of it with the booster coming at the atmosphere ass first... If seperation is at a slower speed then apogee must be lower after boostback, thence reentry interface speed must be lower.

Any Numbers?

Electron recovery shows it's possible to survive what's Peter called "The Wall"
