As preparations for the launch of Sentinel-5P continue on track, the team at Russia's Plesetsk site has bid farewell to the satellite as it was sealed from view in the Rockot fairing. Liftoff is set for 13 October at 09:27 GMT (11:27 CEST).

Since its arrival at the launch site at the beginning of September, Sentinel-5P has been through a series of stringent tests to confirm there was no damage during the flight from the UK.

These tests have made sure that everything is in good working order so that this new satellite will deliver measurement of air quality.
