FLEX for a better understanding of plant health

Using cutting-edge technology, ESA’s FLEX mission is designed to reveal new insights into how plants function by measuring the faint fluorescence they emit during photosynthesis. Although invisible to the human eye, this signal changes with environmental conditions and plant health – allowing scientists to assess vegetation health, and stress.

The FLEX satellite is equipped with the Fluorescence Imaging Spectrometer (FLORIS), an instrument designed specifically to detect and map this delicate glow from space.
