Frequently asked questions
What is Centre national d’études spatiales?
CNES is France’s national space agency, supporting space research, technology and applications through national programmes and European and international cooperation.
When was CNES founded?
CNES was created December 19, 1961. The 1965 Diamant/Asterix launch was a national achievement involving multiple institutions.
How did CNES develop?
On November 26, 1965, a Diamant rocket placed the Asterix satellite in orbit, making France the third country to launch a satellite with its own launch vehicle. That achievement involved a wider national industrial and government effort, not CNES alone. Subsequent developments included the Guiana Space Centre and France’s central contribution to the European Ariane programme, whose first launch took place in 1979.
How is CNES different from ESA?
CNES is France’s national space agency. ESA is an intergovernmental organisation funded by participating countries, including France. National and European programmes can support one another.
Why does CNES matter in space history?
CNES helped connect France’s early independent launch ambitions with a larger European space capability. Its history links national investment, shared infrastructure and international scientific work.
