In base alla situazione Starliner verrà deciso se sarà questa o CST-100 al primo volo operativo a portare astronauti alla ISS.

The 10th commercial crew rotation opportunity to the space station is targeted for early 2025. NASA is planning for either SpaceX’s Crew-10 or Boeing’s Starliner-1 mission in this slot. The Starliner-1 date was adjusted to allow for the post-flight review of the Crew Flight Test and incorporation of anticipated learning, approvals of final certification products, and completion of readiness and certification reviews ahead of that mission.
