The European Union has established the European Science Open Cloud (EOSC), as the “system of systems” Infrastructure where scientists, stakeholders and other types of users can find data, analytical web services, publications, networks and other research resources to carry out their work.

The ESFRI Research Infrastructures form five thematic Science Clusters within the EOSC ecosystem: ENVRI FAIR on the Environment, EOSC Life for the Life and Biomedical Sciences, PANOSC for the Photon and Neutron, SSHOC for the Social Sciences and Humanities and ESCAPE for the Astronomy & Particle Physics. These Clusters are critical to the development of the EOSC integrated environment for the provision of the research resources, whose integration, composition and use by their communities will undoubtedly enhance the emerging EOSC infrastructure. They also provide examples of how shared projects, the Science Projects, can contribute to addressing major societal challenges for Europe and demonstrate how Research Infrastructures can align to support Horizon Europe's missions within EOSC.

This collection of articles highlights the major outputs of these EOSC Future Science Projects: their planning, implementation and the engagement of the relevant scientific community.
