SpaceX was started in 2001. It announced Falcon 9 and messaged its reusability ambitions in 2005.

Falcon 1 wasn’t going anywhere because making rockets is too hard. Falcons 5 and 9 weren’t going anywhere because medium lift is a different ball game. Falcon Heavy wasn’t going anywhere because timing that many engines impossible. Reuse is impossible. (The kerosene will clog everything.) Then, after refly: the total launch market will never be more than $5bn, so reuse is useless.

More recently stainless steel can’t work. Now it’s shifted to reuse and refurbishment being too difficult, or refueling being impossible because of boil-off. Because keeping shit from boiling, apparently, is just unsolved engineering. ಠ_ಠ

Not everything SpaceX does is genius the first time. But they’re ridiculously good at not persisting with stupid. The idea that a dozen rapid depot launches is somehow a gating concern, again, as a tech demo, we’re building the depot eventually, is just such a weirdly small and big concern.

They are persisting with HLS though.

What's your (hot) take on Starship's second stage reusability?

My (noob) understanding is the challenge is achieving reuse (safety, reliability) while keeping the (economically necessary) 100 ton payload capacity.

They are very good in finding money from somewhere to afford all of this.

If this doesn't play out to be reducing costs for the avg american, Musk was able to get funded by the american tax payer nicely.

  • Musk has saved the tax payer (through the government) billions of dollars on every project SpaceX has been involved with. They have earned money by providing vital Internet services to the disconnected and left behind in rural areas all over the world.

    • 9 Million customers. I know a handful of people who use it as a secondary option who were everythign but 'left behind'

      Thats not a lot of people.

      And with the satelites risk and disruption to astronomy and the co2 usage, it might have affected more people negativly than positivly.
