Boeing's CST-100 Starliner crew capsule, which experienced significant technical issues during its first crewed test flight in June 2024, is not expected to return to flight until approximately mid-2026, according to recent NASA and Boeing updates.
The uncrewed return of the Starliner from the International Space Station in September 2024 highlighted problems with its propulsion system, including helium leaks and thruster failures. NASA and Boeing have been conducting extensive reviews and tests to address these issues.
As of June 2026, the target for the next Starliner mission, which would be a post-certification mission, is around mid-2026, though this date remains tentative pending completion of hardware modifications and successful testing. The delay pushes back the timeline for Boeing to achieve regular crew rotation flights to the ISS.
