And he links to a good wrap up of that tweet storm: Elon on Twitter : First (really short) hops with one engine. Suborbital flights with three. : spacex

The tweet below makes sense to me, now that I have watched: KSP Doesn't Teach: Rocket Engine Plumbing
Raptor is *very* complex, even for a staged combustion engine. We’re simplifying as much as possible with each iteration. Throttling down to ~50% is hard, but manageable. Going to 25% would be extremely tough, but hopefully not needed.
The ratio of turbo pump pressures V chamber pressure, versus what power you are running the engine at can create power levels that don't work well. If that makes sense.

I hope they can get away with something like 10 different shaped tiles, rather than every tile being different (like the space shuttle). For the sylindrical parts of the Starship, they can probably get away with just one shape. The nose cone and the control surfaces will be a bigger challenge.
Are those metallic or ceramic?

A SpaceX video was shown when Elon visited students in Flint Michigan this past week: Jay L. DeShetler on Twitter
Someone enhanced sections to show off some interior details of Starship

Okay that’s cool but looking at the video title I was hoping for a video of his talk! But that’s not what I saw.
There is a link to the video of his talk in the investors round table forum, watched it last night.. I’ll try to find a link...
Thanks! What an amazing thing for Elon to do; basically he took a day off to fly to Flint to go to that school and talk to those kids. What cracked me up is that he didn’t really talk down to them, he just talked like he usually does.
To get back on topic for this thread...now I understand what was mentioned upthread, after the Starship animation video was shown there were some stills of the interior that I had not seen before.
Of course it’s just an animation. But everytime I watch Starship animations I want to get onboard and go!
If NASA was ever allowed to do a “competitive, commercial program to build a moon base that is outcome-oriented” SpaceX would crush the competition. Could probably get the start of a moon base in place for a few billion dollars. Peanuts.
Unfortunately, I doubt Congress will budget the funds for a program structured like that.
Unfortunately, I doubt Congress will budget the funds for a program structured like that.
The reason the Everyday Astronaut posted that was because of this:
NASA on Twitter
"It is the stated policy of this Administration and the United States of America to return astronauts to the Moon within the next five years,"
"If commercial rockets are the only option, then so it will be".
From VP Mike Pence at the latest National Space Council meeting.

Yes, and when that administration is gone in less than 2 years policies will change. It’s impossible for NASA to set a goal and maintain a funded program to reach that goal unless the program is really a barrel of pork spread across multiple states. That’s how it gets funded.
There is really no chance that SpaceX can get the funding needed to establish a moon base. Senator Shelby will not allow it.
