The Copernicus Sentinel-3B satellite cocooned in its rocket fairing ready to be placed on the train that will take it to the launch pad.
Sentinel-3B will ride into space on a Rockot on 25 April at 17:57 GMT (19:57 CEST). In orbit it will join its identical twin, Sentinel-3A, which was launched in 2016. This pairing of satellites provides the best coverage and data delivery for Copernicus. Sentinel-3B is the seventh Sentinel satellite to be launched for Copernicus. Its launch will complete the constellation of the first set of Sentinel missions for Europe’s Copernicus programme.
