Earth Science Missions

Seeing Earth from Space

By the end of the decade, the five missions of NASA’s Earth System Observatory (ESO) will be providing a holistic, 3D view of our planet from atmosphere to bedrock. The ESO missions – drawn from recommendations of the 2017 Earth Science Decadal Survey – will provide key information to guide decisions related to climate change, severe weather and other natural hazards, wildfires, and global food production. The NASA-ISRO Synthetic Aperture Radar (NISAR) is the ESO pathfinder mission. Competitively selected, PI-led Earth Explorer missions will augment ESO.
