NASA outlines uncrewed Starliner test flight before crewed missions resume

NASA and Boeing have established a revised plan to return the CST-100 Starliner spacecraft to regular crew rotation flights to the International Space Station. The path begins with an uncrewed flight test targeted for late 2026.

If the uncrewed flight succeeds, NASA and Boeing intend to follow with a piloted Starliner mission in mid 2028. The vehicle is incorporating modified propulsion system valves and updated subsystems intended to resolve issues encountered during previous testing in 2024.
