Watch the replay of the MetOp-SG-A1 and Copernicus Sentinel-5 pre-launch media briefing. This session provides information about these two missions. Speakers include:

• Simonetta Cheli, Director of Earth Observation Programmes at ESA
• Phil Evans, Director-General at Eumetsat
• Simon Brown, Managing Director for Products and Services at the UK Met Office

Following on from the first-generation MetOp series of satellites, MetOp-SG-A1 is the first of Europe’s Second Generation weather satellites, which not only ensure the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more than 20 years, but also offer enhanced accuracy and resolution compared to the original MetOp mission. As part of its instrument package, MetOp-SG-A1 hosts the Copernicus Sentinel-5 advanced imaging spectrometer, which delivers daily global data on key air pollutants, essential climate variables, and stratospheric ozone.

MetOp-SG-A1 and Copernicus Sentinel-5 are scheduled for liftoff on 13 August 2025 CEST aboard an Ariane 6 rocket from Europe’s Spaceport in French Guiana.
