Haven-1 is a planned space station in low Earth orbit that is in development by American aerospace company Vast.[4] It is the first ever commercial space station. The station is expected to launch in Q1 2027[1] atop a SpaceXFalcon 9. The first mission to Haven-1, Vast-1, is expected to launch a crew of four astronauts on board a Crew Dragon spacecraft to the space station for thirty days.[5] More launches are expected to occur using Crew Dragon to shuttle astronauts to and from Haven-1 over the course of its lifespan.[6]
With 45m3 (1,600ft3) of habitable volume,[7] the station will be unable to sustain itself over a long period of time and will rely on the Crew Dragon for long-term missions by using its life support systems.[8] Using Dragon, the station will be capable of sustaining 4-crew missions with 24/7 communication facilities, up to 1,000 watts of power, up to 150kg (330lb) of preloaded cargo mass, and science, research, and in-space manufacturing opportunities for up to 30 days at a time.[9]
The crews aboard the station will also conduct experiments in an attempt to mimic lunar gravity.[10]
Components
Haven-1 interior mockup
Haven-1's propulsion system is being built and provided by Impulse Space.[11] The propulsion system will consist of a storable propellant combination, nitrous oxide and ethane, propellant tanks, fluid lines, valves, sensors, control electronics and software, and Saiph thrusters as a reaction control thruster.[12] The station will also contain a dome for photography and viewing of the Earth for tourists, in addition to always-on internet through onboard Wi-Fi and resting rooms.[13]
In mid-February 2024, Vast announced that it was partnering with El Segundo-based company AnySignal, Irvine-based company TRL11, and Singaporean company Addvalue to provide radio frequency and Inter-satellite Data Relay System connectivity, as well as advanced onboard video solutions for use in Haven-1.[14][15][16]
In August 2024, Vast revealed that Haven-1 will house a microgravity research facility called the Haven-1 Lab, which will serve as the station's microgravity research, development and manufacturing platform. It will have 10 slots, each capable of accommodating payloads weighing up to 30 kilograms and consuming up to 100 watts of power, previously provided by private companies and governments. The first companies to agree to place payloads on Haven-1 have been announced as Redwire and Yuri Gravity.[17] In April 2025, Japan Manned Space Systems Corporation (JAMSS), Interstellar Lab and Exobiosphere were also announced as payload partners for Haven-1.[18]
The hull of the space station had begun its final weld of construction on October 8, 2025.[2][19] With a launch mass of approximately 14,000kg (31,000lb), it will become the heaviest spacecraft ever put into orbit by a Falcon 9 rocket.[2]
Mission
Haven-1 is designed with a three-year lifespan in orbit, which is able to support a total of four short-duration astronaut crews arriving in Crew Dragon spacecraft.[2] Each expedition, starting with Vast-1, will have four crewmembers staying at the station for a total of 10–30 days per flight.[9][2]
Notes: † Never inhabited due to launch or on-orbit failure, ‡ Part of the Almaz military program, ° Never inhabited, lacks docking mechanism.
