Space in the 2020's
summary
Survey of current space efforts lists suborbital rides (Virgin Galactic, New Shepard) as short free‑fall experiences costing $300k tickets while orbital tourism already flies with Inspiration4 four‑day orbital tourist flight. Falcon 9 proves routine first‑stage reuse at ~$2,600/kg to LEO; Starship promises 100% reusable lift but faces Raptor engine and test‑flight reliability problems. The ISS is aging, NASA buys commercial LEO stations (Orbital Reef, Axiom, Lockheed proposals), and lunar plans favor Gateway plus a Starship‑based lander, lunar water ice and commsat constellations for navigation.
