The Helios program is Europe's military optical reconnaissance system consisting of both a space and a ground segment, which commenced service in 1995, jointly funded by the French, Italian and Spanish governments. The Helios I optical observation satellites, launched in July 1995 and December 1999 respectively, can acquire high resolution images of any point on the globe, with daily revisit capability. Helios-1B had suffered a breakdown of its power supply system in October 2004 and could no longer perform any work after operating for just under its 5-year nominal life expectancy.
The Ariane 4 was an expendable space launch system, developed by the Centre national d'études spatiales (CNES), the French space agency, for the European Space Agency (ESA). It was manufactured by ArianeGroup and marketed by Arianespace. Since its first flight on 15 June 1988 until the final flight on 15 February 2003, it attained 113 successful launches out of 116 total launches.
