llamacoffee,

I agree with everything you said and especially with the hope for competition (which in some ways there is, SpaceX is just miles ahead), but I just wanted to point out that basically every rocket ever developed was done with government funding :)

llamacoffee,

SpaceX can likely build and launch a fully expendable version of Starship for about $100 million. Most of that money is in the booster, with its 33 engines. So once Super Heavy becomes reusable, you can probably cut manufacturing costs down to about $30 million per launch.

This means that, within a year or so, SpaceX will have a rocket that costs about $30 million and lifts 100 to 150 metric tons to low-Earth orbit.

Bluntly, this is absurd.

For fun, we could compare that to some existing rockets. NASA’s Space Launch System, for example, can lift up to 95 tons to low-Earth orbit. That’s nearly as much as Starship. But it costs $2.2 billion per launch, plus additional ground systems fees. So it’s almost a factor of 100 times more expensive for less throw weight. Also, the SLS rocket can fly once per year at most.

llamacoffee,

So no in-space engine relight just as we heard recently, but the interesting addition of jettison of the hot stage ring. I really hope that’s temporary!

I also LOVE to see that they want to attempt to relight the raptors and do the flip of Starship survives entry! I wonder how confident they are that it will.

Also in an update, SpaceX noted that both booster engine issues and RCS on IFT-3 were caused by filter blockages and clogged valves. Kind-of fascinating that’s still happening, but I have high hopes they will solve that soon!

The renders for Starship V2 have a dramatically redesigned hot stage mechanism. My guess is as good as any, but it’s possible the current HSR is so bulky and has nothing in common with the future version that they feel it’s actually more representative to throw it away.
