Leonardo builds spectrometer for FLEX Space Mission studying photosynthetic activity globally

  • Leonardo will provide the spectrometer for the FLEX Space mission, which will study the actual photosynthetic activity of vegetation on a global scale
  • The data will provide valuable information on plant health in a changing climate and support sustainable development of ecosystems and agriculture
  • The contract reflects the technology leadership of Leonardo’s electro-optical instruments, which play roles on a range of major Space missions

Today Leonardo-Finmeccanica has signed a contract worth 74 million Euros with the European Space Agency (ESA) to create the FLEX spectrometer for the mission of the same name as part of the ESA’s ‘Earth Explorer’ Programme. From 2022 the FLEX mission will study the health of Earth’s vegetation from a satellite, gathering data that will have implications for Earth’s ecosystems and the maintenance of life on our planet.

Leonardo will lead a consortium of European companies, including primary partner OHB System AG, to deliver the spectrometer. The consortium will spend four years designing, manufacturing and qualifying the system in Campi Bisenzio (Florence). The FLEX instrument will, from a height of 800km, collect the light emitted by plants and break it down into its constituent colours. The sensor can then identify the faint reddish glow emitted during photosynthesis, normally invisible to the naked eye, and precisely identify the ‘fluorescence’ of vegetation, allowing researchers to measure the health of Earth’s ecosystem.
FLEX will orbit in tandem with the European Copernicus Programme’s Sentinel-3 satellite that itself is equipped with another Leonardo Space instrument, the SLSTR radiometer, which measures the sea and land surface temperature. The data will help meet challenges associated with climate change and the sustainable development of ecosystems and will also provide information of value to the agricultural sector.
