Josef Aschbacher, ESA’s Director for Earth Observation Programmes, said, “Since both satellites have a 290 km-wide coverage path and they orbit 180° apart, the time it takes to image the globe will be cut in half to five days once Sentinel-2B is operational.”

The mission mainly provides information for agriculture and forestry and for helping to manage food security. Satellite images are used to determine key information about plants, such as chlorophyll and water content.

This is particularly important for predicting yields effectively and applications related to Earth’s vegetation.

As well as monitoring plant growth, the mission maps change in land cover and monitors the world’s forests. It also provides information on pollution in lakes and coastal waters.

Now in the cleanroom at Europe’s spaceport, Sentinel-2B is already on its stand for the start of a seven-week campaign to test and prepare it to be lofted into orbit on a Vega rocket.

ESA’s launch campaign manager, Paolo Laberinti, said, “It’s good to see that our delicate cargo arrived safe and well.

"We’ve already been able to set up all the technical equipment that we use to test the satellite and connect it to its electrical equipment – so that it’s ready for testing.

“We are off to a flying start and eager to get our baby into orbit so that it can join its twin and do the job of continuously delivering images to monitor our changing world.”

Concurrently, the Sentinel-2 mission control team at ESA's operations centre in Germany has already begun intensive simulation training for the critical launch and early orbit phase.

Sentinel-2B is scheduled for liftoff on 7 March at 01:49 GMT (02:49 CET; 22:49 local time on 6 March).
