Under the COSMOS contract, ASCEND will deliver critical mission operations, systems, and training solutions to support NASA’s Flight Operations Directorate at the Johnson Space Center in Houston, Texas.

Additional programs include the Commercial Crew Program, which expands access to low-Earth orbit and the Artemis program, aimed ultimately at developing a sustained human presence on the lunar surface.

Amentum will provide expertise in Mission Control Center systems, training for both astronauts and instructors, flight controller readiness, training systems development, and mockup environments that replicate real-world conditions, delivering mission-ready solutions as a trusted partner to NASA and the U.S. space enterprise.
