Ireland’s first satellite finished its mission and de-orbited yesterday, 4th September 2025, after almost two years in space. EIRSAT-1 was built and operated by students and staff at University College Dublin as part of the ESA Fly your Satellite! programme.

The small satellite was launched in December 2023 and during its time in orbit, EIRSAT-1 carried out three experiments designed in Ireland, including studying bursts of energy from space, testing new satellite control methods, and trying out special protective coatings.

The mission gave more than 50 students hands-on experience of designing, building, and running a real spacecraft, marking a historic step for Ireland as a spacefaring nation.
