The second satellite in the Sentinel-2 mission for the EU’s Copernicus programme is set for launch from Europe’s Spaceport in French Guiana at 01:49 GMT 7 March (02:49 CET 7 March; 22:49 local time 6 March) aboard a Vega rocket.
The optical imaging Sentinel-2 mission is based on a constellation of two identical satellites: Sentinel-2A, which was launched in June 2015, and the upcoming Sentinel-2B. Although launched separately, the satellites will be placed in the same orbit, separated by 180°.
Every five days, the satellites will jointly cover all land surfaces, large islands, and inland and coastal waters between latitudes 56°S and 84°N, optimising global coverage and data delivery for numerous applications.
The Sentinel-2 mission is the result of close collaboration between ESA, the European Commission, industry, service providers and data users. It is designed and built by a consortium of 60 companies led by Airbus Defence and Space.
