The second Sentinel 2 satellite was launched successfully on 7 March. Sentinel 2A is already in orbit. Together the two satellites will provide global high-resolution Earth observation imagery, optimized for land use analysis, climate change and disaster relief. This image shows part of the Gobi Desert, Mongolia, with vegetation in shades of red and the saline Taatsiin Tsagaan Lake in the upper right. This image highlights erosion and sediment transport, especially from the Baga Bogd Mountains to the south.
The Sentinels are part of the Copernicus environmental monitoring programme, a European Union initiative; UK participation is likely to be affected by Brexit and the associated negotiations. (Copernicus Sentinel data 2015/ESA)
