Boeing Starliner-1[2] is the first operational crewed 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. It is officially scheduled for launch no earlier than December 2021 with a crew of four,[3] though Boe-OFT 2 and Boe-CFT launch delays are pushing this mission into 2022, with launch opportunities in April and September.[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. The fourth seat is likely to be taken by an international partner (Japan, Canada, or European Space Agency) astronaut, as happened with SpaceX Crew-1, with JAXA astronaut Soichi Noguchi.[4][5]

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.[6] 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.[7]
