On 22 April, ESA will launch the Sentinel-1B satellite on top of a Soyuz rocket from Kourou, French Guiana. <br /> <br />It is the twin of Sentinel-1A, launched in 2014, and the fourth satellite of the Copernicus Sentinel series. <br /> <br />With Sentinel-1, ESA and the European Union can already showcase the importance and interest of the space component of the Copernicus programme. <br /> <br />The Sentinel-1 satellites offer numerous services covering applications in the marine environment with oil-spill monitoring or ship detection for maritime security, monitoring land-subsidence, and mapping of forests, water and soils as well as supporting humanitarian aid and crisis situations management. <br /> <br />This video shows a good example of Sentinel services for monitoring Arctic sea-ice and iceberg mapping with the Danish Meteorological Institute in Copenhagen. <br /> <br />More about Sentinel-1: <br />http://www.esa.int/sentinel-1
