The Belgian-backed satellite that reads the future in leaves

A groundbreaking satellite with significant Belgian backing has just launched into orbit, carrying technology developed by the University of Liège that will measure plant photosynthesis directly from space for the very first time. The Flex mission works by detecting the faint red fluorescence emitted by chlorophyll in leaves - a signal invisible to our eyes but perfectly readable by its sensitive instruments. What makes this revolutionary is that it can spot plant stress from drought and heat long before the leaves change color, meaning we can predict crop failures rather than simply observe them after the fact. This early warning system will help scientists and farmers across Europe better understand how our crops, forests and ecosystems respond to climate challenges, and the Belgian research community will play a key role in validating and analyzing the satellite's data.
