Earth Explorers
The need to understand more about the intricacies of how Earth works as a system and how humanity is affecting natural processes is more urgent than ever so that appropriate policies to act on the climate crisis can be put in place and environmental challenges such as those outlined in Europe’s Green Deal can be addressed as effectively as possible. Through FutureEO, the series of world-class Earth Explorer research satellite missions are realised.
