Northrop Grumman footage of its Mission Extension Vehicle (MEV-2) rendezvousing and docking with the Intelsat 10-02 satellite in geostationary orbit. A success: MEV-1 docked Intelsat-901 (2020) and MEV-2 docked Intelsat 10-02 (2021), the first commercial geostationary dockings, extending satellite life by taking over station-keeping. Autonomy attributed to Northrop Grumman.
