FRANKFURT—Europe has launched the seventh of its Sentinel Earth observation satellites as part of its multi-billion-euro Copernicus program to help predict weather phenomena such as El Nino and track the progress of global warming.
The Sentinel-3B satellite, part of a system of satellites that is to monitor Earth, blasted off on board a Rockot rocket from the Plesetsk cosmodrome in Russia’s northwestern Arkhangelsk region at 1:57 p.m. EDT (1757 GMT) on Wednesday.
