Sentinel-3B satellite was launched by a Rockot / Breeze-KM launch vehicle from from the Plesetsk Cosmodrome in northern Russia, on 25 April 2018, at 17:57 UTC (20:57 local time). Sentinel-3B (1200 kg) is an Earth observation satellite, the second in the two-satellite Sentinel-3 mission for Europe’s Copernicus programme, funded jointly by the European Commission and the European Space Agency (ESA). Along with Sentinel-3A, Sentinel-3B will globally monitor ocean, ice and land.
