Robotic Servicing of Geosynchronous Satellites lifts off

Cape Canaveral Space Force Station, Fla. July 22, 2026 - A DARPA-SpaceLogistics partnership launched the first privately owned, operational in-space servicing mission in geosynchronous orbit, paving the way for a new commercial market that will enhance the resilience and sustainability of both commercial and U.S. Government space assets.

The SpaceLogistics Mission Robotic Vehicle (MRV), carrying DARPA's Robotic Servicing of Geosynchronous Satellites (RSGS) highly dexterous robotic servicing system, launched from Space Launch Complex 40 (SLC-40) onboard a SpaceX Falcon 9 rocket, beginning its yearlong journey to geosynchronous Earth orbit (GEO).

Cutting-edge robotic capabilities in orbit

Hundreds of military, government, and commercial satellites reside today in GEO, approximately 22,000 miles (36,000 kilometers) above the Earth. While this altitude is ideal for communications, meteorology, and national security, the technical challenge of servicing satellites lacking custom servicing interfaces has prevented anomaly resolution, upgrades, or repairs for malfunctioning satellites.

• Dual robotic manipulator arms: Built with seven high-strength, high-performance joints and a specialized tool drive, each arm can accommodate multiple interchangeable satellite-servicing tools. MRV will also use the arms to install Mission Extension Pods (MEPs), i.e., propulsion "jet packs" to extend the operational life of existing GEO satellites by six or more years.
• Interchangeable tools and cameras: A suite of modular tools, sensors, and advanced lighting is designed for delicate mechanical interventions.
• Advanced avionics and flight software: Autonomous controls running flight-safe software will execute close-proximity operations safely.

These robotics will perform complex tasks, including in-orbit upgrades, inspections, anomaly resolution, and satellite relocation.

Government-private partnership ushers in new wave of satellite servicing

A government-private partnership between DARPA and SpaceLogistics, a Northrop Grumman company, forms the foundation of the RSGS program. DARPA led the development of the robotic servicing suite, working closely with the Naval Research Laboratory to develop the flight robotic payload elements.

SpaceLogistics integrated the robotic suite with its Mission Robotic Vehicle (MRV) and will own and operate the integrated spacecraft. Once in orbit, SpaceLogistics has the rights to use the robotic payload to provide commercial servicing, including the installation of company-funded MEPs.

Additionally, a 2024 agreement with NASA brought considerable civil spaceflight and robotics expertise to the program, advancing U.S. capabilities in In-space Servicing, Assembly, and Manufacturing (ISAM).

"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 journey to GEO

The MRV uses electric propulsion to efficiently raise its orbit over the next year, reaching GEO where it will begin its operational mission.

To ensure survival through launch stresses and the harsh environment of space, the integrated spacecraft underwent rigorous spaceflight qualification testing. This included launch vibration stress simulations, electromagnetic compatibility testing, and extreme thermal-vacuum exposures at NRL's specialized facilities.

After DARPA's initial on-orbit capability demonstrations, SpaceLogistics is required to provide data on the MRV serving missions to the government to enable understanding of the long-term operation of the RSGS payload. Additionally, DARPA intends to transfer the RSGS program to the U.S. Space Force to coordinate MRV commercial servicing with its Servicing, Mobility, and Logistics (SML) portfolio throughout the MRV's expected 10+ year operational life.

"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."
