    MISSION OVERVIEW
    • Type: Earth Science
    • 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.
