Background
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.
