DARPA and its partners are preparing to launch the Mission Robotic Vehicle, a robotic spacecraft designed to demonstrate advanced satellite servicing capabilities in geosynchronous orbit. The mission is part of DARPA’s Robotic Servicing of Geosynchronous Satellites program, known as RSGS. The program is scheduled to reach its next major milestone with a launch planned for summer 2026.
The Mission Robotic Vehicle is designed to address the technical challenges of servicing satellites in geosynchronous orbit, where many commercial, civil, and government spacecraft operate. The vehicle includes a highly dexterous robotic servicing suite intended to support complex on-orbit tasks, including inspection, anomaly resolution, satellite relocation, and potential upgrades.
DARPA is leading development of the robotic front-end in collaboration with the U.S. Naval Research Laboratory and NASA. SpaceLogistics, a Northrop Grumman company, is leading integration of the robotic payload with its spacecraft platform, which is based on the company’s flight-proven Mission Extension Vehicle technology.

The RSGS program is intended to demonstrate how robotic servicing can extend the useful life and operational flexibility of satellites in geosynchronous orbit. The ability to inspect, relocate, or service spacecraft after launch could help reduce dependence on fully disposable space assets while supporting more resilient satellite infrastructure.
Geosynchronous satellites are typically designed with significant redundancy because they are difficult to access after deployment. Robotic servicing technologies may create new options for maintaining high-value spacecraft, addressing operational anomalies, and supporting future space infrastructure with greater flexibility.
With launch planned for 2026, the Mission Robotic Vehicle represents an important step toward practical on-orbit satellite servicing. The demonstration could help support future commercial and government missions requiring more sustainable, serviceable, and adaptable space systems.
About DARPA
The Defense Advanced Research Projects Agency, or DARPA, is the central research and development organization of the U.S. Department of Defense. Established in 1958, DARPA works with government, industry, and academic partners to develop advanced technologies intended to create and prevent technological surprise for national security. Its research programs span aerospace systems, autonomy, communications, electronics, artificial intelligence, materials, biotechnology, and other advanced defense-related capabilities. DARPA’s Robotic Servicing of Geosynchronous Satellites program reflects the agency’s broader role in advancing high-risk, high-impact technologies with potential applications for national security, commercial space infrastructure, and future mission resilience.
