New call open for submission

The new Horizon Europe EU Space Research call 2026 (HORIZON-CL4-2026-SPACE-03) opened on 10 March 2026. With a total budget of €90.97 million, the call offers a wide range of new collaboration opportunities for the space community. The call submission deadline is 3 September 2026 (17:00:00 Brussels time).

EU Space Research aims to foster a cost-effective, competitive, and innovative space industry and research community. Under Horizon Europe Cluster 4 – Space (Destination 5), HaDEA is funding projects that prepare future evolutions of the EU Space Programme components, foster the EU space sector’s competitiveness, reinforce its independent capacity to access space, and secure its autonomy of supply for critical technologies.
