NASA announced on September 18, 2026, that it had awarded SpaceX three additional crew transportation missions to the International Space Station through a contract modification under the Commercial Crew Transportation Capability (CCtCap) contract. The modification covers Crew-15, Crew-16 and Crew-17 and is valued at $946 million for all three missions and related services, including ground, launch, in-orbit, and return and recovery operations, cargo transportation, and lifeboat capability while docked at the station. It brings SpaceX's total missions under the contract to 17.

The firm fixed-price, indefinite-delivery/indefinite-quantity modification has a period of performance running through 2030, with mission readiness dates in 2027 and 2028, and raises the total CCtCap contract value with SpaceX to $5.92 billion. NASA said the award followed a notice of intent issued in May to purchase the additional missions, and that the sole source modification does not preclude future contract modifications for additional transportation services.

NASA awarded the CCtCap contracts to Boeing and SpaceX in 2014 under its Commercial Crew Program, and certified SpaceX for crew transportation in November 2020. According to the agency, SpaceX's Crew-12 mission was in orbit docked to the space station at the time of the report.
