• 1994 April 13 - GOES 8 - Launch Site: Cape Canaveral. Launch Vehicle: Atlas I. Mass: 2,105 kg (4,640 lb). Perigee: 35,770 km (22,220 mi). Apogee: 35,807 km (22,249 mi). Inclination: 0.10 deg. Period: 1,436.20 min.

  Geostationary Environmental Satellite. Stationed at 75 deg W. Space craft engaged in investigation of spaceflight techniques and technology (US Cat A). Launch vehicle put payload into supersynchronous earth orbit with MRS trajectory option. Positioned in geosynchronous orbit at 90 deg W in 1994-1995; 75 deg W in 1995-1999 As of 5 September 2001 located at 74.78 deg W drifting at 0.019 deg E per day. NASA announced that GOES-8 was "de-orbited" (presumably moved to a sub-synchronous orbit) on May 5, 2004 after 10 years of service. As of 2007 Mar 11 located at 87.46E drifting at 4.935W degrees per day.

• 1995 May 23 - GOES 9 - Launch Site: Cape Canaveral. Launch Vehicle: Atlas I. Mass: 2,105 kg (4,640 lb). Perigee: 35,809 km (22,250 mi). Apogee: 35,911 km (22,314 mi). Inclination: 0.20 deg. Period: 1,435.90 min.

  Stationed at 135 deg W. Launch vehicle put payload into supersynchronous earth orbit with MRS trajectory option. Positioned in geosynchronous orbit at 90 deg W in 1995; 135 deg W in 1996-1998; 98-105 deg W in 1998-1999 As of 5 September 2001 located at 103.62 deg W drifting at 0.009 deg W per day. As of 2007 Mar 10 located at 159.81E drifting at 0.002W degrees per day.

• 1997 April 25 - GOES 10 - Launch Site: Cape Canaveral. Launch Vehicle: Atlas I. Perigee: 35,780 km (22,230 mi). Apogee: 35,799 km (22,244 mi). Inclination: 0.40 deg. Period: 1,436.30 min.

  Geosynchronous. Stationed over 105.7W Launch vehicle put payload into supersynchronous earth orbit with MRS trajectory option. Positioned in geosynchronous orbit at 105 deg W in 1997-1998; 135 deg W in 1998-1999 As of 6 September 2001 located at 135.09 deg W drifting at 0.037 deg W per day. As of 2007 Mar 11 located at 59.64W drifting at 0.009W degrees per day.
