On Becoming a Space-Faring Civilization
summary
DART deliberately changes an asteroid moonlet’s orbit by about 30 minutes instead of the planned 1 minute, proving kinetic deflection and prompting ESA’s Hera follow‑up; reusable rockets are cutting launch cost to roughly $1,800 per kg with Falcon 9 after ~25 reuses while Starship (about 9 m diameter, 275 t, 70 m tall) flies experimental missions and has been recovered in tests; ISS runs continuously since 2000 but faces deorbit ~2030 with SpaceX contracted; Shackleton crater holds billions of tons of water ice and orbital refueling and fuel‑depot transfers are expected within a few years.
