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 1A was lifted into orbit during the mission ‘Ariane 40 | Helios 1A’, on board a Ariane 40 space rocket.
The launch took place on July 7, 1995, 4:23 p.m. from Ariane Launch Area 2.
