A Pitstop in Space

Rethinking Space Bound Maintenance
NASA’s On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1), a mission that will be the first to robotically refuel a satellite not designed to be serviced, and will also demonstrate assembly and manufacturing technologies and capabilities, has passed its mission critical design review (CDR). This is an important milestone that paves the way for the construction of the spacecraft, payloads, and ground system. The Electrical Engineering Division’s (EED) will support the development of three major subsystems for OSAM-1: Power Servicing Unit (PSU), Video Distribution System Unit (VDSU) and the Command and Data Handling (C&DH) Unit.
During its mission, the OSAM-1 servicer will rendezvous with, grasp, refuel and relocate a government-owned satellite to extend its life. But OSAM-1’s effect will not end there.
The benefits are many. OSAM-1’s capabilities can give satellite operators new ways to manage their fleets more efficiently, and derive more value from their initial investment. These capabilities could even help mitigate the looming problem of orbital debris.
Successfully completing this mission will demonstrate that servicing technologies are ready for incorporation into other NASA missions, including exploration and science ventures. NASA is also transferring OSAM-1 technologies to commercial entities to help jumpstart a new domestic servicing industry.
