Boeing Starliner-1[3] is the first operational crew mission of the Boeing Starliner to the International Space Station (ISS), and is planned to be the fourth orbital flight mission of the Starliner overall.[4] It is officially scheduled for launch no earlier than April 2022,[1] with an additional launch opportunity in September.[2] Either this flight or SpaceX Crew-4 will launch in April 2022; the other will launch at a later date.[1] It will transport members of a future ISS Expedition to the ISS. This would only be the fourth U.S. spaceflight with a female commander, after STS-93, STS-114, and STS-120.


As this marks the first operational flight of Starliner, a Russian cosmonaut is not expected to be on board as Roscosmos has stated they do not want to put Russian cosmonauts on either Starliner or Crew Dragon until they have flown successful Commercial Crew Program flights.[5][6] On 21 May 2021 NASA announced JAXA astronaut Koichi Wakata as the fourth member of the crew, in cooperation with JAXA as NASA's international partner.[7]

This mission will be the first reuse of a Starliner spacecraft. The vehicle was initially flown as the first uncrewed Orbital Flight Test mission in December 2019. On 22 December 2019, commander Sunita Williams announced the name "Calypso" for the spacecraft.[8] Calypso will now be used for Boe-CFT as Spacecraft 2 is used for Starliner Orbital Flight Test-2.

Jeanette Epps was added to the Starliner-1 mission on 25 August 2020.[9] Koichi Wakata was officially added to the Starliner-1 mission on 21 May 2021.[7]
