The European Space Agency’s Copernicus Sentinel-3B was launched on 25th April 2018 from the Plesetsk Cosmodrome in northern Russia. The hard work and dedication by the teams at ESA, Eumetsat, France’s CNES space agency, industry, service providers and data users made the launch of the satellite a huge success. Sentinel-3B joined its twin, Sentinel-3A, in orbit for systematically monitoring & change detection of Earth’s oceans, land, ice, and atmosphere.
The pairing of the two satellites optimizes coverage and data delivery for Copernicus. This mission delivers data within three hours of sensing, 24 hours a day, 365 days a year to offer optical remote sensing services using satellite imagery.
