Haven-1

Haven-1 is a planned space station in low Earth orbit that is in development by American aerospace company Vast.[1] If launched, it will be the first ever commercial space station. The station is expected to launch in Q1 2027 atop a SpaceX Falcon 9.[2] 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.[3] More launches are expected to occur using Crew Dragon to shuttle astronauts to and from Haven-1 over the course of its lifespan.[4]

With 45 m3 (1,600 cu ft) of habitable volume,[5] 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.[6] 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 150 kg (330 lb) of preloaded cargo mass, and science, research, and in-space manufacturing opportunities for up to 30 days at a time.[7]

The crews aboard the station will also conduct experiments in an attempt to mimic lunar gravity.[8]

## Components

Haven-1 interior mockup

Haven-1's propulsion system is being built and provided by Impulse Space.[9] 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.[10] 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.[11]

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.[12][13][14]

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 kg (66 lb) 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.[15] In April 2025, Japan Manned Space Systems Corporation (JAMSS), Interstellar Lab and Exobiosphere were also announced as payload partners for Haven-1.[16]

## Development

The hull of the space station had begun its final weld of construction on October 8, 2025.[17][18] With a launch mass of approximately 14,000 kg (31,000 lb), it will become the heaviest spacecraft ever put into orbit by a Falcon 9 rocket.[17] On January 20, 2026, Haven-1 began its assembly for launch.[2]

Unlike Haven-2 which is funded by a NASA contract, Haven-1 is entirely privately funded, and since its completion in 2025 been fully paid for.[17] Until January 20, 2026, Haven-1 was scheduled to launch in late 2026, however, this would be delayed to the first quarter of 2027.[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.[17] Each expedition, starting with Vast-1, will have four crewmembers staying at the station for a total of 10–30 days per flight but will typically consists of two weeks at the station.[2][7][17] Vast's CEO Max Haot stated that the station will undergo a series verification events including an unmanned docking of a Dragon 2 before the first manned crew is sent on Vast-1.[2] Haot stated that this verification process could take anywhere from two weeks to three years.[2]
