About
Vast Space is a commercial space company founded in 2021 by billionaire Jed McCaleb, with the ambitious goal of building large-scale space habitats for long-duration human occupation. The company is taking a phased approach starting with Haven-1, a single-module space station designed to launch on a SpaceX Falcon 9 rocket and dock with SpaceX Dragon crew vehicles. Haven-1 is designed to host four astronauts for commercial research, training, and manufacturing missions. Vast has a launch services agreement with SpaceX and a NASA traction contract under the Commercial Low Earth Orbit Destinations program, which is funding development of post-ISS commercial space stations. The longer-term vision is to build increasingly larger space stations culminating in artificial gravity habitats that could support permanent human populations in orbit. Vast has recruited talent from aerospace, defense, and technology sectors and is developing Haven-1 on an aggressive timeline to become operational before the ISS retirement.
