Earth Science Missions

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.

In addition, small spacecraft and satellites help NASA advance scientific and human exploration, reduce the cost of new space missions, and expand access to space.
