France: ESA plans to launch the eighth Earth Explorer satellite to track the health of the world’s vegetation. The satellite will carry out this task by detecting and measuring the faint glow that plants give off while converting sunlight and the atmosphere’s carbon dioxide into energy. Presently, photosynthetic activity cannot be measured from space, but the Fluorescence Explorer or FLEX’s novel sensor will observe this faint glow. According to ESA, the satellite, which is planned for launch by 2022, will improve researchers’ understanding of the way carbon moves between plants and the atmosphere and how photosynthesis affects the carbon and water cycles.
