The European MetOp-SG-A1 (Meteorological Operational Satellite – Second Generation, model A) was successfully launched on the second commercial flight of Ariane 6 from Kourou. Carrying six state-of-the-art instruments for atmospheric imaging and sounding, the satellite will significantly enhance weather forecasting and climate research.
Operating at around 800 km in a polar sun-synchronous orbit, MetOp-SG-A1 will deliver critical data on temperature, precipitation, winds, pollution, and aerosols. These observations are expected to improve short-term forecasting and deepen understanding of climate change.
The University of Liège played a central role through its Centre Spatial de Liège (CSL), which calibrated key instruments such as 3MI and Metimage, tested subsystems, provided flight components, and developed advanced optical simulation tools. AMOS, a Liège-based company and spin-off of the university, also contributed to the mission.
The project reflects international collaboration and highlights the University of Liège’s expertise in space science and technology.
