Arianespace successfully launched the Sentinel-1B satellite for the Copernicus program on behalf of the European Commission, under a contract with the European Space Agency (ESA). It also orbited on this mission, the French CNES space agency’s Microscope satellite, and three CubeSats for the ESA Education and Knowledge Management Office’s Fly Your Satellite! program. The Soyuz launcher lifted off on April 25, 2016 at 6:02 pm (local time) from the Guiana Space Center (CSG) in French Guiana.
