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.<br>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).
