Overview
CNES is the French government's space agency and the architect of Europe's independent launch capability. France established CNES in 1961 — earlier than ESA itself — and drove the creation of the Ariane rocket family that gave Europe sovereign access to space. CNES operates the Guiana Space Centre in Kourou, French Guiana, where all European orbital launches take place.
As the largest national contributor to ESA's budget, France shapes the strategic direction of European space policy. CNES also operates its own Earth observation, defence and scientific satellites, and has deep partnerships with NASA (Mars missions), ISRO (Megha-Tropiques climate satellite) and other agencies.

Key Programmes
Ariane Programme
CNES initiated the Ariane launcher family in the 1970s, evolving through Ariane 1–5 to today's Ariane 6. France remains the programme's largest funder and technical leader.
Guiana Space Centre
CNES operates Europe's spaceport at Kourou — the world's best-located launch site for GEO missions at 5°N latitude.
SPOT / Pléiades Earth Observation
France's high-resolution optical Earth observation programme, now operated commercially through Airbus Defence & Space.
Mars Science Contributions
CNES built the SuperCam instrument on NASA's Perseverance rover and contributed to multiple Mars mission payloads.
