Associated Launch Sites
  • Kourou After the agreement with newly independent Algeria for France to evacuate their launch sites in that country, a location near Biscarosse was selected for French missile testing. However since only launches westwards across the Bay of Biscay could be made from this site, it was unsuitable for France's Diamant orbital launch vehicle. After reviewing 14 potential sites, a location in the South American French colony of Guiana was selected. This would allow over-water launches to a tremendous range of possible orbital inclinations -- from -100.5 deg to 1.5 deg. Being near the equator, it would provide the maximum assist from the earth's rotation for launches into equatorial orbits. The decision was formalized in April 1964 and in July 1966 ELDO chose the site for future launches of the Europa II launch vehicle. More...

  • NStar c - . Mass: 4,050 kg (8,920 lb). Nation: Japan. Agency: Stellat. Manufacturer: Cannes. Program: N-STAR. Class: Communications. Type: Civilian communications satellite. Spacecraft: Star bus. USAF Sat Cat: 27461 . COSPAR: 2002-035B. Apogee: 35,801 km (22,245 mi). Perigee: 35,772 km (22,227 mi). Inclination: 0.0000 deg. Period: 1,436.10 min. Launch delayed from late June. The N-Star c satellite was an S-band satellite for mobile telephone communications for NTT DoCoMo of Japan. N-Star c had a communications payload built by Lockheed Martin and used the Star 2 bus from Orbital. The small Star 2 satellite had a dry mass around 800 kg and was the first flight of a new Orbital hydrazine/nitrogen tetroxide liquid apogee propulsion system with a 500N thrust apogee engine developed by Japan's IHI. As of 2007 Mar 9 located at 135.92E drifting at 0.012W degrees per day.
