The Next Steps to Becoming a Space-Faring Civilization
summary
DART proves kinetic deflection works: DART changed orbit by >30 minutes after a 500 kg impactor at 6.6 km/s sprayed ~1,000 tonnes of debris. Falcon 9 now flies ~ $3,000/kg to LEO while SLS costs ~$58,000/kg; Starship aims for under $500/kg but has not yet completed orbital reuse. Artemis 2 did a crewed lunar flyby (Apr 2026); lunar landers require orbital refueling (never done), Shackleton may hold billions of tons of ice, and Psyche reaches a metal-rich asteroid in 2029.
