On Becoming a Space-Faring Civilization
summary
Planetary defense proves workable: DART shifted the Didymos moonlet by about half an hour and shows rubble‑pile asteroids respond to kinetic impact. Rocket economics change access: Starship is 9 m wide with ~100 tonne payload and promises $25–$200/kg while Falcon 9 routinely reuses boosters (Falcon 9 reused ~250 times), SLS costs approach $2B a launch, and ISS resupply now runs ~$65M per cargo flight. Concrete infrastructure plans include orbital fuel depots, Moon polar ice mining, inflatable habitats, and asteroid processing concepts like Honeybee.
