Sentinel-2B is a European optical imaging satellite that was launched on 7 March 2017. It is the second Sentinel-2 satellite launched as part of the European Space Agency's Copernicus Programme, and its orbit will be phased 180° against Sentinel-2A. The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands. It will provide information for agriculture and forestry, among others allowing for prediction of crop yields.[4]

Mission history

A €105 million contract for the construction of the spacecraft was signed in March 2010 by ESA's Director of Earth Observation Programmes and the CEO of Astrium Satellites.[5] It was completed in June 2016,[6][7] and the satellite was transported to the European Space Research and Technology Centre (ESTEC) for the test campaign.[8][9]

Launch

The spacecraft arrived at the Centre Spatial Guyanais on 6 January 2017 for pre-launch operations.[10]

Launch took place at the nominal time of 01:49:24 UTC on 7 March 2017 on board Vega flight VV09. The spacecraft was injected into its target orbit at 02:47:21 UTC.[2][11]
