On Becoming a Space-Faring Civilization
summary
States that asteroid-deflection tests (DART) changed a moonlet’s orbit by half an hour instead of 70 seconds, showing rubble‑pile behavior and huge ejecta; shows Starship tests with live HD reentry video, heat damage to flaps but a controlled ocean splashdown; lists lift costs: Atlas V ~$25,000/kg, Falcon 9 ~$8,000/kg, Vulcan ~$4,500/kg, Starship ~\$100/kg (aspirational); argues infrastructure milestones—orbital fuel depots (rotating tanks to settle propellant), Artemis timelines (Artemis 1 success, Artemis 2 planned), Shackleton pole resources and lava‑tube skylights—make routine space presence plausible.
