NASA has awarded three additional missions to Space Exploration Technologies Corporation (SpaceX) of Hawthorne, California, for crew transportation services to the International Space Station as part of its Commercial Crew Transportation Capability (CCtCap) contract. The CCtCap modification, following the agency’s notice of intent to procure the flights in December 2021, brings the total missions for SpaceX to nine and allows NASA to maintain an uninterrupted U.S. capability for human access to the space station.This is a firm fixed-price, indefinite-delivery/indefinite-quantity contract modification for the Crew-7, Crew-8, and Crew-9 missions, bringing the total contract value to $3,490,872,904. The period of performance runs through March 31, 2028. The current sole source modification does not preclude NASA from seeking additional contract modifications in the future for additional transportation services as needed.In 2014, NASA awarded the CCtCap contracts to Boeing and SpaceX through a public-private partnership as part of the agency’s Commercial Crew Program. Under CCtCap, NASA certifies that a provider’s space transportation system meets the agency’s requirements prior to flying missions with astronauts.SpaceX was certified by NASA for crew transportation in November 2020, and currently its third crew rotation mission for the agency is in orbit. As part of the missions, SpaceX’s Crew Dragon spacecraft and Falcon 9 rocket transport up to four astronauts along with critical cargo to the space station.
