The ongoing reductions in space launch cost are just insane. SpaceX's Starship, at high launch cadence, could bring launch costs down by a factor of nearly 1,000 vs the 2000s. Great analysis by @lizvstein medium.com/prime-movers-lab/…

Space launch, like other sectors, has a virtuous cycle where scale brings down costs, which expands the market, which brings down costs. medium.com/prime-movers-lab/…

Could we use them to send a bunch of mirrors/prisms into space and reduce sunlight on earth by 1-2% until we get CO2 levels back down?

Check out the unbelievable scale of Starship, @ramez. It makes Falcon 9 look like a bottle rocket!

I live next to two 34-story, 125 meter high buildings standing next to a park. I can not pass it without imagining the Starship launch tower in their place.

That's some crazy cost reductions. I hope to see more incredible cost reductions like this moving forward. Maybe It won’t be as insane/crazy as this, though. But, It would be nice if I'm proven to be wrong.

It is obviously early, and we need more actual launch data, but due to *both* scaling and learning you would not have to work too hard to convince me that the orange line is too conservative, and that instead it should be a hyperexponential. But we shall see.

What I want to know: what space manufacturing industry makes sense to be the first one and why? Also, does much cheaper space long bring asteroid mining within the realm of practicality?

Can you grow giant crystals in free fall better than in gravity? And what are giant crystals good for?

Mark, is this something you approve of? SpaceX was founded by an immigrant and sponsors people for H-1Bs and green cards.

One order of magnitude down, two to go!
