On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1)

Building on NASA’s history of upgrading and maintaining assets in space, NASA’s OSAM-1 mission is developing an unprecedented capability for a robust, cost-effective space infrastructure.

Active Mission

OSAM-1 is a robotic spacecraft equipped with the tools, technologies and techniques needed to extend satellites' lifespans – even those not originally designed to be serviced. OSAM-1 is funded by the Technology Demonstration Missions program, which is located at Marshall Space Flight Center in Huntsville, Alabama and within NASA’s Space Technology Mission Directorate headquartered in Washington, D.C. The mission is led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
