The European Space Agency has cleared another hurdle on the road to launching the second generation of the MetOp (Meteorological Operational) Earth-studying weather satellites. In early August 2025, the team sealed the MetOp-SG-A1 within the fairing of its Arianespace Ariane 6 rocket.

What is it?

The MetOp-SG-A1 is a specialized weather satellite hosting a suite of cutting-edge science instruments, including those for the Copernicus Sentinel-5 mission, which will help monitor Earth's atmosphere with ultra precision.

This A-type satellite will complement a B-type satellite, the MetOp-SG-B1, which ESA plans to launch next year. The pair of satellites will allow for better scanning and analysis of Earth's climate, including variables such as air pollutants and greenhouse gases.
