ESA teams ready for space
24 April 2018
The launch of Sentinel-3B will complete the Sentinel-3 constellation and represents the culmination of months of training to fly Europe's latest Copernicus satellite.
The Sentinel-3B satellite has been at the Plesetsk cosmodrome in Russia since mid-March, being readied for its ride into space on 25 April at 17:57 GMT (19:57 CEST).
It will join its twin, Sentinel-3A, in orbit to systematically monitor Earth's oceans, land, ice and atmosphere. The pairing of the two satellites optimises coverage and data delivery for Copernicus.
