The teams that will fly Sentinel-5P are training intensively for launch, ensuring that everyone knows their job and can react to any emergency.

A 'team of teams' at ESA's mission control centre has spent months preparing to assume control of Europe's next Earth observation mission, and the final weeks before launch have been the most intense.

Sentinel-5P - the P refers to 'precursor' - is the first mission for Copernicus dedicated to monitoring our atmosphere.
