From Wikipedia, the free encyclopedia
The Centre National
d'Études Spatiales (CNES) is the
French government space agency (administratively, a "public
administration with industrial and commercial purpose"). Its
headquarters are located in central Paris and it's placed under the
supervision of the french Ministries of Defense and Research. It
operates out of the Centre Spatial
Guyanais, but also has payloads launched from other space
centres operated by other countries. CNES formerly was responsible
for the training of French spationauts, but the last of them were
transferred to the European Space Agency in
2001.
CNES
programs
Access to
space
Assured access to space underpins any global, coherent space
policy. France was the 3rd space power to achieve this distinction,
sharing technologies with Europe to boost development of the Ariane
launcher family.
International competition in space is fierce, so launch services
must be tailored to space operators’ needs. The new versions of Ariane 5 can launch large
satellites or perform dual launches. And the Vega and Soyuz-2 small and medium-lift
launchers are now set to round out this range.
Alongside its European partners, CNES also offers its expertise
in satellite deployment.
Sustainable development
Space resources are vital for learning more about the Earth and
its evolution. Earth observation and measurements offer ways to
ensure sustainable stewardship of our planet.
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 and Jason-1 oceanography satellites,
the Argos system, Envisat and—in the near future—Jason-2 and the Pleiades
satellites.
Civil
applications
Space technologies are set to offer society a number of advances
in the coming years through the emergence of new services. Space is
a great equaliser for bridging territorial disparities in
education, health and citizenship. For example, CNES has developed
the concept of a “communications-enabled village” that combines the
high data rates offered by satellite technology with terrestrial
technologies.
CNES is also taking part in the Galileo
navigation programme alongside the European Union and ESA, and—in a
wider international context—in the Cospas-Sarsat search-and-rescue
system.
Security
and defence
In an ever-more-complex world, independent
information-gathering, location and civil and military intelligence
capabilities are a prerequisite for good, independent and
responsive decision-making.
In addition to Spot and the future Pleiades
satellites, CNES is working for the defence community as prime
contractor for the Helios satellites.
GMES—a
joint initiative involving the EU, ESA and national space
agencies—pools space resources to monitor the environment and
protect populations, but it also encompasses satellite support for
armed forces and for European organisations on humanitarian or
peacekeeping missions.
Ongoing
missions
France’s contribution to the International Space Station is
giving French scientists the opportunity to perform original
experiments in microgravity. The CNES is also an innovator, and is
currently studying formation flying, a technique whereby several
satellites fly components of a much heavier and complex instrument
in a tightly controlled configuration. CNES is collaborating with
other space agencies in a number of projects. Orbital telescopes
such as INTEGRAL, XMM-Newton and COROT, and space probes like Mars Express, Venus Express, Cassini-Huygens and Rosetta, operated by the European space
agency are revolutionizing our knowledge of the Universe and our Solar System. Recent
satellites such as Demeter (earthquakes). Joint
missions with NASA result in PARASOL and
CALIPSO (radiation budget)
satellites. Megha-Tropiques Mission is a
planned collaborative mission with the Indian Space Agency (ISRO) designed to
study the water cycle and radiation dynamics, and assist
observation from other satellite platforms. CNES plays a major role
in the construction and operation of the Soil Moisture
and Ocean Salinity satellite.
UFO
Archive
Announcement
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 they were
often reported to the Gendarmerie.
In the last 2 decades of the 20th century, France was the only
country with officially paid UFO investigators, employed by CNES's
UFO section GEPAN, later known as SEPRA and now as GEIPAN.
Publication
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 than 1,600 sightings since 1954 and will
include all future UFO reports obtained by the agency, through its
GEIPAN unit.
Skeptical
critics
The French skeptics have heavily criticized the quality of the
work done by the GEPAN, and show a lot of flaws in their
methodologies. See (in French):

ovnis du CNES – 30 ans d’études officielles. www.book-e-book.com.

Tracking
stations
The CNES has several tracking stations.
