Greece is launching its first-ever state-owned satellite constellation, marking a major milestone in the nation's technological advancement. The project, funded by the Greece 2.0 plan and supported by the European Space Agency, will see the development of 13 satellites designed for enhanced environmental monitoring, disaster response, and national security. This ambitious initiative underscores Greece's commitment to space technology and data sovereignty for a secure and sustainable future.
