Starliner Crew Flight Test

Starliner Crew Flight Test was the first crewed flight of Boeing's CST-100 Starliner spacecraft to the International Space Station. NASA astronauts Butch Wilmore and Suni Williams launched from Space Launch Complex 41 at Cape Canaveral Space Force Station on June 5, 2024, with Wilmore commanding the mission and Williams serving as pilot. Starliner docked to the ISS the next day, but NASA later chose to return the spacecraft uncrewed while Wilmore and Williams remained aboard the station and returned to Earth later on SpaceX Crew-9.

Outcome
Partially successful crewed flight test. Starliner Calypso launched Wilmore and Williams and docked with the ISS, validating major crewed-flight objectives, but helium leaks and reaction-control thruster problems led NASA to return the spacecraft uncrewed. Calypso landed safely at White Sands Space Harbor; Wilmore and Williams remained aboard as Expedition 71/72 crew and later returned on Crew-9.
