  • Ariane 5 The Ariane 5 was a completely new design, unrelated to the earlier Ariane 1 to 4. It consisted of a single-engine Lox/LH2 core stage flanked by two solid rocket boosters. Preparatory work began in 1984. Full scale development began in 1988 and cost $ 8 billion. The design was sized for the Hermes manned spaceplane, later cancelled. This resulted in the booster being a bit too large for the main commercial payload, geosynchronous communications satellites. As a result, development of an uprated version capable of launching two such satellites at a time was funded in 2000. More...

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...

  • Essaim 1 - . Mass: 120 kg (260 lb). Nation: France. Agency: DGA. Manufacturer: EADS Astrium. Class: Military. Type: Electronic intelligence satellite. Spacecraft: Myriade. USAF Sat Cat: 28494 .

The Essaim demonstrator was a system of several micro-satellites (Essaim means 'swarm' in French) for 'analysis of the electro-magnetic environment of the Earth's surface' (electronic intelligence). DGA, the French Ministry of Defence's procurement agency, developed the project. The system also comprised a ground control segment and a ground station for data processing. It was called a 'demonstrator' since the mission's objective was to assess the operational capability of such a system, paving the way for the next generation. The Essaim satellites were based on EADS Astrium's Myriade multipurpose micro-satellite. In early 2000, the DGA awarded the contract for the development, manufacturing of this turnkey system of micro-satellites and associated ground segment. Under the contract, EADS Astrium was also responsible for personnel training and system operations during the three-year life duration of the programme.
