Twin Copernicus Sentinel-3 Satellite Launched in Northern Russia

PLESETSK COSMODROME, RUSSIA - APRIL 25: In this handout provided by the European Space Agency (ESA), the second Copernicus Sentinel-3 satellite, Sentinel-3B, awaits liftoff aboard a Rockot launcher April 25, 2018 at the Plesetsk Cosmodrome in northern Russia. Sentinel-3B joins its twin, Sentinel-3A, in orbit, the pair of identical satellites providing increased coverage and data delivery for Europe's Copernicus programme, the largest environmental monitoring programme in the world. The satellites carry the same suite of cutting-edge instruments to measure oceans, land, ice and atmosphere. (Photo by Stephane Corvaja/ESA via Getty Images)
