EIRSAT 1 is the first irish satellite. It is a 2U-CubeSat. University College Dublin (UCD) is leading the development, launch and operation of this CubeSat, in partnership with Queen’s University Belfast (QUB) and five Irish companies, Resonate Ltd, ENBIO, SensL, Parameter Space and MOOG Dublin.

The CubeSat will carry two experiments: a test of a novel gamma-ray detector module and an experiment with thermal coatings for spacecraft.

EIRSAT 1 was selected by ESA's "Fly Your Satellite!" Program in 2017 to be deployed in orbit from the ISS in 2018 or 2019. Possibly it may fly on the maiden flight of the Ariane-62 launch vehicle.
