> MISSION BRIEFING // HUMAN EXPLORATION

Starliner-1 is the first operational flight of a Starliner spacecraft to the International Space Station as part of NASA's Commercial Crew Program. Due to problems with the Starliner spacecraft's RCS attitude control system during the Crew Flight Test mission in 2024, this mission has been re-scoped to not carry a crew by NASA. It will instead deliver necessary cargo to the orbital laboratory and allow in-flight validation of the system upgrades implemented following the Crew Flight Test mission last year.
