The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.
Find out more about space activities in our 23 Member States, and understand how ESA works together with their national agencies, institutions and organisations.

The images show an agricultural area in southern Germany in late May 2017. The Copernicus Sentinel-2 image (left) was acquired at 20 m spatial resolution. This allows agricultural parcels and other landscape features such as roads to be distinguished. The Copernicus Sentinel-3 image (centre) captures the land-surface temperature, which is essential for estimating evapotranspiration, but here with a pixel size of around 1 km. By using advanced machine-learning algorithms, data from the two sensors can be fused, thus obtaining a 20 m representation of land-surface temperature (right) which can then be used to produce 20 m evapotranspiration maps.
