Space Flight in the 2020s
summary
Falcon 9 drives today’s space tourism and cargo market at roughly $2,600/kg, while Atlas V remains near $25,000/kg; Crew Dragon charters run about $100M per flight and AX-1 pays station fees near $5,000/day. Starship is a nine‑meter vehicle with 33 Raptor engines and FAA limits, aiming for full reuse to drop launch costs toward airline fares; SLS shows slow, failure‑prone testing. ISS represents ~$100B of infrastructure with aging modules expected to retire by ~2030; Gateway in a NRHO becomes the preferred lunar staging point and reusable landers (starship the only fully reusable proposal) enable sustained bases in lava tubes.
