This Call for Research Proposals (APR) prepares CNES' scientific space research programme for 2026; the call concerns national projects as well as projects from ESA and other agencies.
The RPA covers the following activities: preparatory studies, scientific support for space missions under development, support for missions in operation, experiments in microgravity, support for operations, experiments on research aircraft, ground and analog simulations, international calls for tenders and missions of opportunity.
The RPA does not cover R&T proposals or research grants for doctoral and post-doctoral students.
ATTENTION The proposals for balloon experiments will not be processed in the APR process due to the time lag in the timetable.
Laboratory research teams are invited to submit their proposals by 26 September 2025 midnight on the dedicated platform.
