ESA and CNES
Through its Launch Vehicles Directorate (DLA), CNES also manages the programme’s technical and financial aspects, and has responsibility for prototype qualification flights.
DLA teams provide expertise in:
- project management
- management control
- contract oversight
- quality assurance and dependability
Since 2005, the restructuring of the space sector has led CNES to forge closer ties with ESA oversight teams and provide support to them. Joint ESA/CNES teams are currently being formed to lead the way.
As for the previous series of launchers, Arianespace is in charge of marketing Ariane 5 and conducting launch operations at the Guiana Space Centre.
Arianespace operates all Ariane 5 launches, the 1st qualification flight (501) being the only exception. CNES holds a 34% share of Arianespace, which has a total of 50 shareholders from 12 European nations.
