Mission Concept

The NASA-ISRO Synthetic Aperture Radar (SAR), or NISAR, Mission will make global integrated measurements of the causes and consequences of land surface changes. NISAR will provide a means of resolving highly spatial and temporally complex processes ranging from ecosystem disturbances, to ice sheet collapse and natural hazards including earthquakes, tsunamis, volcanoes, and landslides.

NISAR's unprecedented coverage in space and time will reveal forces acting within the Earth and on its surface, biomass variability, and response of ice masses far more comprehensively than any other measurement method. The detailed observations will reveal information about the evolution and state of the Earth's crust.
The NISAR Mission: All-Weather Day and Night Imaging
The NASA-ISRO SAR (NISAR) Mission will acquire radar images of surface changes globally. Rapid sampling over years to decades will allow for understanding Earth processes and change.
Radar penetrates clouds and operates day and night. It produces images that are detailed enough to see local changes, and has broad enough coverage to measure regional trends. The NASA-ISRO Synthetic Aperture Radar (NISAR) mission, a collaboration between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organization (ISRO), will acquire images of ecosystem changes globally. Rapid sampling over years to decades will allow for understanding disturbance, degradation, and response. NISAR's unprecedented coverage in space and time will reveal forces acting within the Earth and on its surface and variability in ice masses and biomass far more comprehensively than any other measurement method. The detailed observations will reveal information that will allow us to better manage resources and prepare for and cope with global change.
