Mission brief

What is happening

United Launch Alliance is launching Starliner-1 on a Atlas V N22 from Space Launch Complex 41 at Cape Canaveral SFS, FL, USA. It is a crewed mission heading to Low Earth Orbit.

Why it matters

Crewed flights carry people, which makes them the highest-stakes launches any provider runs and the ones held to the strictest flight-readiness standards.

Programme

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.
