COSMOS4HE proposal is the successor of COSMOS2020plus and previous projects of Space NCP network. The consortium consists of NCP organisations from 16 countries balancing geographical coverage as well as diversity in level of expertise. The overall aim of COSMOS4HE is to support the professionalisation of the services rendered by the National Contact Points in Cluster 4 thematic area of Space in Horizon Europe and provide additional services targeting Space clients and applicants at EU level and beyond. The activities are structured according to the proposal’s specific objectives: 1) to increase the quality and support harmonisation of Space NCPs services, 2) to lower the entry barriers for newcomer applicants, to attract new types of players and applicants from widening countries, as well as to raise the quality of submitted proposals, 3) to increase the visibility of the thematic area of Space to new types of players by organizing matchmaking activities and ensuring bilateral communication about the crosscutting issues throughout Horizon Europe for the benefit of the European R&I community. The consortium will closely cooperate with the two other Cluster 4 NCP networks in thematic areas Digital and Industry developing synergies. Collaboration will be also sought with other NCP networks, EEN and space stakeholders aiming at maximising outreach and impact. Special focus will be put on broadening participation.
