Second EU radar Sentinel satellite launches

The European Space Agency has launched a second radar satellite into the EU's new Sentinel constellation. Sentinel-1b was carried into orbit by a Soyuz rocket that flew out of Sinamary in French Guiana. The new platform will monitor shipping lanes for pollution and icebergs, and survey land surfaces for evidence of subsidence - to name just three of the myriad applications for radar imagery. Sentinel-1b will work alongside the 1a spacecraft, which was launched in 2014. Operating in the same orbit but separated by 180 degrees, the pair will be able to map the entire Earth every six days.
