Programs

CNES concentrates on five areas: *Access to space *Civil applications of space *Sustainable development *Science and technology research *Security and defence


Access to space

Sustainable development

CNES and its partners in Europe—through the Global Monitoring for Environment and Security initiative (GMES)—and around the world have put in place satellites dedicated to observing the land, oceans, and atmosphere, as well as to hazard and crisis management. The best-known are the SPOT satellites flying the Vegetation instrument, the Topex/Poseidon, Jason-1 and Jason-2

UFO Archive

In December 2006, CNES announced that it would publish its UFO archive online by late January or mid-February. Most of the 6,000 reports have been filed by the public and airline professionals. Jacques Arnould, an official for the French Space Agency, said that the data had accumulated over a 30-year period and that UFO sightings were often reported to the

. In the last two decades of the 20th century, France was the only country whose government paid UFO investigators, employed by CNES's UFO section GEPAN, later known as SEPRA and now as GEIPAN. On March 22, 2007, CNES released its UFO files to the public through its website. The 100,000 pages of witness testimony, photographs, film footage, and audiotapes are an accumulation of over 1,600 sightings since 1954 and will include all future UFO reports obtained by the agency, through its GEIPAN unit.
