ERMIS

The ERMIS Constellation is a Greek space mission for in-orbit technology demonstration of various communication and Earth observation technologies. The satellite constellation consist of three CubeSat-type small satellites, two 6U and one 8U, that were all launched to low Earth orbit together on the Transporter-16 flight of the Falcon 9 rocket on 30 March 2026. The two smaller satellites are designed to test 5G connectivity for Internet of Things and the larger satellite (ERMIS-3) also includes an ATLAS-1 laser terminal from the Lithuanian company Astrolight. The mission was developed by the National and Kapodistrian University of Athens with the support of the EU's and ESA's Greek CubeSat In-Orbit Validation programme.
