2024 call for proposals funded in 2025

Every year, CNES solicits research proposals from science laboratories for the following year. Once accepted, proposals form part of our medium-term plan.

The call for proposals to be funded in 2025 will be open from 3 June to 25 September 2024.
This year, proposals for balloon-borne experiments will not go through the APR process due to a shift in schedule and will be assessed separately. Technical files and their accompanying financial annex should be submitted by e-mail to ballons-apr@cnes.fr before 30 April 2024.

Documents detailing CNES balloon proposals and technical elements can be viewed here: Balloon-borne experiments

To submit an application, connect to the Science Calls platform.
