The Ministry of Digital Governance, through the General Secretariat of Telecommunications and Post (GSTP) and the Hellenic Space Center (HSC), publishes a national Request for Information (RFI) aiming to map the Greek scientific, technological, industrial, educational, and informational capabilities related to the potential future utilization of the International Space Station (ISS).
The Call invites entities to submit proposals (Expressions of Interest) for experiments, technology demonstrations, as well as educational and public outreach activities, which could leverage the microgravity environment and the unique position of the ISS in low Earth orbit.
This Call is preparatory, exploratory, and non-binding. It does not constitute a competition or procurement, grant, funding commitment, or flight guarantee and does not create any claims against the State.
