ESA's FLEX Mission, Dedicated to Space Photosynthesis Observation, Set for September 15 Launch

The European Space Agency's (ESA) FLuorescence EXplorer (FLEX) mission is scheduled to launch on September 15, 2026. This satellite is specifically designed to observe plant photosynthesis globally from space, measuring solar-induced chlorophyll fluorescence (SIF). The mission aims to provide critical insights into how vegetation responds to climate change, including reactions to drought and heat, and its role in the global carbon and water cycles, which could aid in developing climate-resilient agriculture and protecting natural ecosystems.
