SpaceX doing amazing work and Musk being an egomaniacal $hole are not mutually exclusive

I encourage as many people as possible who are less wacko than Musk to try to beat him at his own game. Will be good for everyone.

I thought it was going to stay upright! that would have been very funny. 1 engine out on the way up, who would have thought getting 33 full flow combustion rocket engines to startup at the same time would be so hard.. /s

Honestly wondering if that's a Stage 0 issue: those outer engines get primed by the launch ring AFAIK.

oh interesting, i did not know that. Just before ignition there was a bottom up view of what looked like gaseous o2 pouring out, was that the priming? They do that to get the pumps spinning to get pressure to the pre-burners so they can ignite and then get more power to turbo pumps to bring everything up to full power correct?

The ocean landing is so cool. I believe they said that the next one they are going to try to land back at the tower? Seems plausible now.

I think that might be a second IFT away personally: I imagine they'd like to see no engine relight issues on descent for at least one more mission first, since slamming it into Starbase would be a shame.

It does seem like they could do with a more isolated launch site (with the tank farm in a huge concrete bunker) before trying to catch Super Heavy

iirc only 3 ignite for the landing burn, those engines are freaking monsters. I love how small they are, the latest Raptor revision is so slim and compact. The power density is just mind boggling.

You can see for yourself in the video - all 13 center engines attempt to light, and all but one do so.

Similar to ship, they start up more engines than needed in case a few fail, then immediately shut down the extra engines.

Wait, did it land or not? Retrieved or sunk? Couldn’t tell from the video.

It did not land. The plan was not to attempt a landing. But it maintained a controlled descent into the ocean and splashed down upright.

Honest question, did they sink the remaining fuel? Or did they just burnt all remaining fuel whilst hovering? I would imagine that's pretty toxic.

Edit: Thanks for the answers!

I am one of the people skeptical about Elon’s specific claims of Starships abilities specifically about his Mars ambitions. Today’s test, if the Starship reentry is as successful as the booster soft landing will be absolutely a great achievement and a 100% mission success. This demonstration keeps SpaceX on schedule for their part of the Artemis 3 mission.

Keeping the mission parameters simpler (no “refueuling” or door bay demonstrations as far as I am aware, just orbital insert and reentry) definitely shows they are capable of the basic ideas of how they want Starship to work, especially for Starlink missions.

The team should be proud.

It simulated a landing over the ocean, but there was nothing there to actually catch it.

Guess they didn't want to sacrifice "Of Course I Still Love You" for this test.

Methane and oxygen are not very toxic.
