The Intelsat VI-series were the sixth generation communications satellites built by the Hughes Aircraft Company for the Intelsat Corporation. From 1989 to 1991, a total of five satellites, each weighing 4,330 kg, were launched into GEO. One satellite (Intelsat 603) was left stranded in LEO after a launch failure in 1990, where it was subsequently rescued during the maiden flight of Space Shuttle Endeavour in May 1992


  • Requires the Space Shuttle addon installed to view Intelsat 603, however the other four satellites can still be visited even without that addon installed
