ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station) Icon ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station)
The ECOsystem Spaceborne Thermal Radiometer on Space Station (ECOSTRESS) mission will study how the worlds ecosystems use water..

The Applied Sciences' DEVELOP National Program addresses environmental and public policy issues through interdisciplinary research projects that apply the lens of NASA Earth Observing Systems to community concerns around the globe.

NASA's Earth Science Program is dedicated to advancing Earth remote sensing and pioneering the scientific use of satellite measurements to improve human understanding of our home planet.
