The CST-100 Starliner is a crewed spacecraft developed and operated by Boeing under NASA's Commercial Crew Program to carry astronauts to and from the International Space Station. It completed an uncrewed test flight in December 2019 and its first crewed test flight in June 2024, though thruster failures during that crewed approach to the station led NASA to bring the astronauts home aboard a SpaceX Dragon instead, leaving Starliner's path to routine crewed missions still in progress.
