The Fluorescence Explorer (FLEX) was selected in November 2015 as the next Earth Exploration Mission by the European Space Agency (ESA) and will map vegetation fluorescence to quantify photosynthetic activity. This information will improve our understanding of the way carbon moves between plants and the atmosphere and how photosynthesis affects the carbon and water cycles. It will also lead to better insight into plant health and stress. More information are available at the following link.
