Space Habitation

Space habitation technology develops the commercial space stations, life support systems, and orbital infrastructure that will replace the International Space Station when it retires in 2031, creating permanent commercial destinations in low Earth orbit for research, manufacturing, tourism, and government missions. The space habitat market reached $4.5 billion in 2025 growing at 21% CAGR, while the space tourism market reached $1.6 billion and is projected to reach $46.8 billion by 2034. NASA's Commercial LEO Destinations (CLD) program provides $2.1 billion over 5 years with Phase 2 contracts of up to $1.5 billion.

Vast secured $500 million in total funding ($300 million Series A plus $200 million debt) in March 2026 at a $2 billion valuation, backed by Balerion Space Ventures, IQT, Qatar Investment Authority, and Mitsui. Vast's Haven Demo made it the only company to fly and operate its own commercial spacecraft. Haven-1 targets a 2027 launch with Haven-2 designed for permanent human presence by 2030. Axiom Space raised $350 million in February 2026 plus $100 million from Hungary's 4iG Group, targeting a two-module free-flying station by 2028 and a four-module ISS successor. Axiom-4 launched in June 2025, and the Payload, Power, and Thermal Module targets a 2027 launch.

Blue Origin and Sierra Space's Orbital Reef completed System Definition Review with NASA in June 2025 with construction beginning in 2026 and operations by 2027. Voyager Space's Starlab (joint venture with Airbus, Mitsubishi, MDA Space) completed Commercial Critical Design Review with $183 million disbursed to date and a single-module launch on SpaceX Starship planned for 2029. Sierra Space secured Series C funding and holds approximately $1.43 billion in NASA CRS-2 obligations for Dream Chaser cargo delivery. Gravitics won a $125 million contract from Axiom Space for its StarMax pressurized module providing 400 cubic meters of volume (nearly half the ISS in a single module).

The ISS decommissioning is confirmed for 2031, with the final crew arriving in mid-2030 to initiate retrograde maneuvers and SpaceX contracted to develop the U.S. Deorbit Vehicle for up to $843 million. The controlled re-entry will target the South Pacific near Point Nemo. NASA's CLD program acquisition is currently on hold as of January 28, 2026, as NASA aligns timelines with national space policy.

For founders, space habitation in 2026 represents a once-in-a-generation market creation event as commercial stations replace government infrastructure. The most fundable approaches serve life support and environmental control systems for commercial stations, in-space manufacturing technology leveraging microgravity for pharmaceutical and materials production, space station module and systems components (Gravitics' $125 million Axiom contract demonstrates the supply chain opportunity), crew logistics and training services, and the research platform operations that connect scientific customers with orbital facilities.
