Vast-1

Vast-1 is a planned private spaceflight to the Haven-1 space station, planned to launch no earlier than May 2026^[2] by American aerospace company Vast.^[3] Vast-1 is expected to launch on a Falcon 9 rocket, using a Crew Dragon vehicle, both manufactured by SpaceX.^[4][5] The stay on the station is planned to last no more than 30 days.^[5] The spaceflight will include four astronauts who will be trained by SpaceX on their Crew Dragon capsule through simulations and formations.^[6]

Mission

During the mission, the crew will conduct various experiments, relating to both science and in-space manufacturing.^[8] As of June 2023, these experiments are unknown, however, they may be both internal and external.^[9]

At some point during the mission, the Haven-1 space station's propulsion system will cause the station to rotate, providing artificial gravity, similar to the gravity one would experience on the Moon.^[10][11] If successful, it would be the second time artificial gravity has been deliberately produced in a crewed spacecraft, with the first being on NASA's Gemini 11 in 1966.^[12]

Future flights

Vast's contract with SpaceX includes the option for a second crewed mission to Haven-1 with a launch scheduled for no earlier than 2026, called Vast-2.^[13]
