Yep, and the exhaust from the Raptors does look very much like a humongous Bunsen burner
-
I rather think that Ukraine has been very glad of Starlink.
-
Do you want to return to a dirt-grubbing substance agrarian economy? I certainly don't.
-
Point one: it isn't a waste. Point two: what Musk has spent is chicken feed compared to what would be needed.
-
I'm conflicted about Musk. On the one hand I applaud what he's doing to make space travel affordable and sustainable, but on the other his Starlink junk just annoys the heck out of me, though I can see that he needs the money to fund Starship etc. Like I say, no simple answer.

Some videos of Raptor engines test firing and gimbaling
-
The inner engines are gimbaled using hydraulic actuators but the outer ones are fixed. The latest version uses electric actuators, which a much faster.
-
The outer ring of engines are fixed, but the 13 inner engines are gimbaled.
-
I don't know how detailed the telemetry is. For all I know each engine may have been monitored to the last degree.
-
Or possibly an Auto dismantling Event.
-
Telemetry data would be good. I could see 6 Raptors out before the bang, and could see some flaming out (Or exploding) during the launch. Given that SpaceX reckon that they need 31 running to reach orbit, this was never going to proceed. Guess they ran it as long as they did to gather as much data as they could.

I saw a documentary on the Saturn V computer (Possibly YT), showing all the work by women threading impossibly fine wire through the ferrite cores (I'm old enough to remember core store), and feeling angry and depressed that all that effort would be thrown away, ending up at the bottom of the Atlantic. Hopefully the days of chuck-it-away will soon be over.
-
Mutterings that I've heard talk about another launch in August. Booster 9 and Ship 26 are pretty much ready. SpaceX will learn a lot from this test.
-
SpaceX have a production line of Boosters and Ships. Booster 9 and Ship 26 are waiting in the wings, with Booster 10 and Ships 27-30 in production. Ship 25 is complete and waiting but may not fly at this time.
-
But a realistic one.
-
Elon said that getting off the pad and past the tower would be a success. The Orbital launch platform is still in one piece, so success.
-
Trying again.

How big Is the universe?

March 2021 6 sessions, March 2022 8 sessions, March 2023 0 sessions, and I can see April going the same way, then it's May and the end of astronomical darkness. I wonder why I bother.
-
There's no point. It doesn't matter how advanced the equipment becomes global warming just means ever increasing cloud cover. I think there's no longer any future in astronomy from this vile swamp of a country.
-
Yep, a pressurisation issue.
-
Here's the SpaceX YT
-
Livestream is live.
-
They're having to thread a very tight needle through the Caribbean, the MSIB and NOTAMs have been issued for a few days now.

I think the launch widow opens at 7.00 CDT which is 13.00 BST.
