EUROPEAN SPACE AGENCY (ESA)
The European Space Agency is responsible for the Ariane, Vega and Soyuz development programmes at the GSC. ESA owns most of the facilities and has been contributing to the funding of the GSC since 1975.
At the GSC, CNES is responsible for the overall coordination of the launch base, the reception of satellites, launcher tracking systems and the protection of people, property and the environment.
As launch operator, Arianespace operates the launch complexes to deploy its range of Ariane, Soyuz and Vega launchers. Its mission starts with the signing of the launch contract and continues until the satellite has been put into orbit.
ArianeGroup produces the Ariane 5 launcher and is involved in the development of Ariane 6.
At the GSC, the Italian company Avio coordinates the preparation of Vega and Vega-C launchers.
The role of manufacturers, in charge of the plants which produce fluids and fuels for the launchers, is crucial for the smooth running of each launch.
CNES, ArianeGroup, Arianespace and Avio work with a network of companies located at the GSC.
