Following liftoff from Cape Canaveral on July 21 aboard a SpaceX Falcon 9 rocket, the Robotic Mission Vehicle (MRV) hosting the NASA-backed Robotic Geosynchronous Satellite Servicing (RSGS) payload is now en route to geosynchronous Earth orbit, where it will use its advanced robotics to service spacecraft.

RSGS leverages NASA’s space robotics expertise, aligned with the agency’s broader goals of advancing American capabilities for service, assembly and manufacturing in space that can be applied to space commerce and exploration.

Funded by the Defense Advanced Research Projects Agency (DARPA), the RSGS program uses twin dexterous robotic arms designed and developed by the U.S. Naval Research Laboratory. DARPA provided the robotic arm assembly for integration into Northrop Grumman’s MRV, the nation’s first multi-mission space robotics service. The spacecraft will inspect and upgrade satellites in orbit by installing small propulsion modules, called mission extension capsules, extending the operational life of existing spacecraft by years.

RSGS brings together government agencies and industry to test advanced robotic systems in space. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, began supporting the RSGS mission in 2024 under an interagency agreement with DARPA.

NASA’s contributions to the mission build on its legacy of servicing missions, including the Hubble Space Telescope servicing missions and the Robotic Refueling Missions to the International Space Station. NASA’s support for the RSGS program includes the development of dynamic simulation and analysis tools, software analysis for performance verification, and a team of flight robot operators who will support highly technical procedures in orbit. Hundreds of satellites are in geosynchronous orbit. Of these, fully operational satellites are usually dismantled early because they run out of fuel or their equipment becomes obsolete. RSGS establishes a critical U.S. capability to extend the life of spacecraft in orbit, enabling more innovative and cost-effective mission designs.
