Organization

ESA is prime contractor of the JUICE project. ESA is in charge of the spacecraft launch, navigation towards Jupiter and injection into orbit around Jupiter.

CNES is contributing to funding of the JUICE project through ESA's mandatory scientific programme and directly through the national programme via France's participation in the spacecraft's instruments. CNES, representing France on ESA's Science Programme Committee, is responsible for the French deliverables.

CNES ensures, for all French participants (CNRS, universities) the prime contractorship of the French contribution to JUICE. As such:

  • it is funding the contributions of the French laboratories;
  • it is overseeing development of the French contributions;
  • it is supplying supports where needed by laboratories for quality insurance, mechanics, thermals, components expertise, etc.;
  • it is managing the interface with ESA for technical and programmatic aspects;
  • it is funding the French mission science activities.
