## Key points

- NASA plans to add six more post-certification missions to SpaceX's commercial crew contract.
- This extension is driven by uncertainty around Boeing's CST-100 Starliner ever being certified for crewed flights.
- NASA reversed its plan to extend crew rotations to eight months, retaining six-month ISS missions instead.
- With the extension, SpaceX missions will cover ISS crew transport through late 2030, the station's planned retirement.
- Boeing's contract was reduced from six to four missions, and Starliner-1 is not on the latest NASA manifest.

**Companies:** SpaceX, Boeing
**Countries:** United States
