NASA engineers work on the Restore-L payload in the high bay inside the Space Station Processing Facility (SSPF) at NASA's Kennedy Space Center in Florida, on May 16, 2019. Restore-L, managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, is an in-flight robotic satellite servicer spacecraft. The center is celebrating the SSPF’s 25th anniversary. The SSPF was built to process elements for the International Space Station. Now it is providing support for current and future NASA and commercial provider programs, including Commercial Resupply Services, Artemis 1, sending the first woman and next man to the Moon, and deep space destinations including Mars.
