ESA launches environmental satellite Sentinel-1B

The European Space Agency launched a satellite on 25 April to track the progress of global warming, as part of its Copernicus project. The Sentinel-1B joins its identical twin, Sentinel-1A, in orbit to deliver information for various services, from monitoring ice in polar seas to tracking land subsidence, the ESA said. It will also respond to disasters such as floods. Apr 26, 2016
