It is manufactured by Boeing, with the Commercial Crew Program (CCP) of NASA as the anchor customer. The spacecraft consists of a reusable crew capsule and an expendable service module.
Josh Aaron Cassada is an American physicist, test pilot, and NASA astronaut. Prior to his selection to join NASA in 2013, Cassada served as a test pilot in the US Navy, and has over 3,500 hours in more than 40 aircraft, and 23 combat missions. In August 2018, Cassada was selected for CTS-1, the first operational mission of the Boeing CST-100 Starliner, but subsequently reassigned to SpaceX Crew-5.
Nicole Victoria "Duke" Aunapu Mann is an American test pilot and NASA astronaut. She is an F/A-18 Hornet pilot and a graduate of the US Naval Academy, Stanford University, and the US Naval Test Pilot School. She has over 2,500 flight hours in 25 types of aircraft and 200 carrier landings, and has flown 47 combat missions in Iraq and Afghanistan. Mann completed astronaut training in 2015 and was assigned in August 2018 to Boe-CFT, the first crewed test flight of the Boeing CST-100 Starliner, but subsequently reassigned to the SpaceX Crew-5, becoming the first female commander of a NASA Commercial Crew Program launch.
Boeing Crew Flight Test will be the first crewed mission of the Boeing Starliner and the third orbital flight test of the Starliner overall after the two uncrewed flight tests, OFT-1 and OFT-2 in 2019 and 2022.
Boeing Starliner-1 also called Post Certification Mission-1 (PCM-1) is planned to be the first operational crew mission of the Boeing Starliner to the International Space Station (ISS) as part of the Commercial Crew Program. It would be the fourth orbital flight mission of the Starliner overall. It is scheduled to launch no earlier than early 2025, transporting members of a future ISS Expedition.
The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational no earlier than 2025. NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.
