Behind the Science

NISAR is helping us to track disasters, monitor ecosystems and crops, study glaciers and ice sheets, and to understand how Earth’s surface moves and changes. The data NISAR is providing will help protect lives, support the management of natural resources, and give us a deeper understanding of our changing planet.
