🇫🇷 Centre National d’Études Spatiales (CNES) – France’s National Space Agency

The Centre National d’Études Spatiales (CNES) is France’s national space agency, responsible for shaping and implementing the country’s civil space policy and supporting strategic national interests in space. Founded in 1961 under President Charles de Gaulle, CNES is one of the world’s oldest space agencies and was created to ensure French independence in space and sovereign access to orbit.  

Headquartered in Paris with major centres in Toulouse, Évry, and the Guiana Space Centre in French Guiana, CNES manages a broad portfolio of space programs, research and technology development, satellite missions, and launch systems.  

As of 2024–2025, CNES employs over 2,300 space professionals and operates with a budget of approximately €3.0 billion, making it one of Europe’s most significant national space agencies.

📜 Historical Background

CNES was established in 1961 as part of France’s effort to become an independent space power during the Cold War era. In 1965, France achieved its first successful orbital launch with the Diamant rocket, placing the Astérix satellite into orbit and marking France as the third country to independently launch a satellite after the United States and the Soviet Union.  

Over the decades, CNES has driven innovation in launch vehicles, satellite technology, and scientific missions, often in cooperation with European and international partners.
