APR - 2026 call for proposals funded in 2027
As part of its PARS space research support programme, CNES launches an annual call for contributions (APR) from French scientific laboratories to submit scientific research proposals for the following year. Once accepted, these proposals are incorporated into the medium-term plan for the following year.
The 2025 call for research proposals to be funded in 2026 will be open from:
30 April to 15 June 2026 (closing at midnight)
To submit an application, connect to the Science Calls platform.
Beware: this year, proposals for balloon-borne experiments will go through the APR process . For more information send an e-mail to ballons-apr@cnes.fr or go to the webpage Balloon-borne experiments.
For flight requests only, balloon flight appendix should be completed and attached to the technical proposal. This appendix and documents detailing CNES balloon proposals and technical elements can be viewed here: Balloon-borne experiments.
