Orion
Program: Orion. Objective: Communications. Overview: Domestic communications satellite network.
Major Events:

  • 1994 November 29 - Orion 1.  Spacecraft: Eurostar 2000. Mass: 2,358 kg (5,198 lb). Launch Site: Cape Canaveral. Launch Vehicle: Atlas IIA.

    34 Ku-band transponders for TV. Stationed at 37.48 deg W. Launch vehicle put payload into supersynchronous earth orbit with IFR trajectory option. Positioned in geosynchronous orbit at 37 deg W in 1994-1999 As of 5 September 2001 located at 37.54 deg W drifting at 0.010 deg W per day. As of 2007 Mar 11 located at 37.60W drifting at 0.015W degrees per day.

  • 1999 May 5 - Orion 3.  Spacecraft: HS 601. Launch Site: Cape Canaveral. Launch Vehicle: Delta 3.

    The Centaur RL-10B-2 second stage engine's combustion chamber ruptured at the beginning of the second burn. The hot gases already in the chamber vented, putting the stage/spacecraft assembly into an uncontrollable tumble. The Orion 3 communications satellite ended up in a useless parking orbit of 162 km x 1378 km x 29.5 deg. It was to have served the Asia-Pacific region for Loral Orion with 33 Ku-band and 10 C-band transponders.
