Vast Space is advancing Haven-1, positioned as the world's first commercial space station, through multiple integration and testing phases ahead of a 2027 launch. The company has completed pressure and load testing of the primary structure and is manufacturing flight-ready components in-house.
What's happening
- Haven-1 primary structure has completed pressure and load acceptance testing and returned to Long Beach for final weld inspections and integration.
- Vast has integrated critical subsystems including life support, power, and thermal control systems, with 12 deployable solar array wings undergoing acceptance inspection.
- The flight computer (Vast Control Unit) is entering electromagnetic compatibility testing to verify it does not interfere with onboard systems.
- Haven-1 is designed for 4 crew members with 45 cubic meters of habitable volume, targeting a 425 km orbit at 51.6 degrees inclination.
Why it matters
- Haven-1 represents the first American-made space station primary structure built in over 20 years, establishing domestic capacity for commercial orbital infrastructure.
- In-house manufacturing of critical components including life support systems, thermal control, and power distribution reduces supply chain risk and production dependencies.
- Completion of pressure and load testing demonstrates advancement through qualification gates required before orbital flight operations begin.
- A 2027 launch date establishes a near-term commercial alternative to government-owned stations, opening new markets for crew and cargo missions.
Going deeper
- Vast has built two Haven-1 primary structures (qualification and flight articles) in-house at Long Beach as of the latest update.
- Haven Demo serves as an in-orbit testbed for critical systems, having achieved mission success after deploying from a rideshare mission and achieving power-positive status.
- Vast developed Hall thruster technology in-house based on a license from NASA JPL's H10 thruster design for use on Vast satellites.
- The company manufactures laser retroreflector arrays internally to provide range and orientation data during rendezvous and docking operations.
The fine print
- 2027 launch date is stated as the target; all subsystem testing and qualification must be completed before orbital flight.
- Haven-1 design accommodates 4 crew members with 80 cubic meters of pressurized volume and 13,200 watts of power generation.
- Both qualification and flight articles have been built and tested; final integration and acceptance testing remain ahead of the launch timeline.
