Robotic satellite-servicing mission to geosynchronous orbit lifts off

Cape Canaveral, Fla. — A SpaceX Falcon 9 lifted off from Space Launch Complex 40 on July 22 carrying SpaceLogistics’ Mission Robotic Vehicle (MRV) with DARPA’s Robotic Servicing of Geosynchronous Satellites (RSGS) payload, inaugurating what the partners describe as the first privately owned, operational in‑space servicing mission in geosynchronous orbit. The spacecraft will use electric propulsion to gradually raise its orbit over roughly a year before beginning work in GEO.

The mission is designed to move satellite servicing from demonstrations to routine operations, addressing a long‑standing gap in GEO, where hundreds of military, civil, and commercial spacecraft operate some 22,000 miles above Earth but typically lack built‑in interfaces for repairs or upgrades. Once on station, the MRV is intended to conduct inspections, anomaly resolution, relocations, and hardware upgrades, including installation of Mission Extension Pods—propulsive “jet packs” that can add six or more years to aging satellites’ lives.

SpaceLogistics, a Northrop Grumman company, integrated the government‑developed robotic payload onto its MRV and will own and operate the combined spacecraft, with rights to provide commercial servicing using the system. DARPA led development of the dexterous robotics suite in partnership with the U.S. Naval Research Laboratory, and a 2024 agreement brought NASA expertise in in‑space servicing, assembly, and manufacturing.

“By partnering with industry from the start, we ensure the capability transitions into a sustainable, commercially viable service,” said James Shoemaker, Ph.D., RSGS program manager. “This partnership creates a new market and allows the cost of maintaining this infrastructure to be shared, benefiting both the government and the entire space industry.”

The MRV carries dual seven‑joint robotic arms with a powered tool drive and interchangeable end‑effectors, supported by modular cameras, sensors, and lighting for precision work at close range. Autonomous, flight‑safe software will manage proximity operations. Ahead of launch, the integrated spacecraft underwent vibration, electromagnetic compatibility, and thermal‑vacuum testing at NRL facilities.

After DARPA completes initial on‑orbit demonstrations, SpaceLogistics must provide servicing data to the government to inform long‑term operations of the RSGS payload. DARPA also plans to transfer the program to the U.S. Space Force to coordinate commercial servicing within the Service’s Servicing, Mobility, and Logistics portfolio over the MRV’s expected decade‑plus lifetime.

The launch advances a line of life‑extension services SpaceLogistics began earlier in the decade with its Mission Extension Vehicle dockings on Intelsat satellites, while expanding into more complex robotic work. It also marks a notable U.S. government‑industry step on in‑space servicing following NASA’s 2024 cancellation of its OSAM‑1 refueling mission.

“DARPA and its partners are launching a new era of satellite servicing,” Shoemaker said. “We are creating a brand-new capability that will fundamentally change how we think about the sustainability and resilience of satellites in geosynchronous orbit. By developing high-dexterity robotics and autonomous controls, we are retiring the biggest technical risks to jumpstart a new commercial market and strengthen the infrastructure for an American-led space ecosystem.”
