Mission Concept Overview
The NASA-ISRO Synthetic Aperture Radar (SAR), or NISAR, Mission would make global integrated measurements of the causes and consequences of land surface changes. NISAR would provide a means of disentangling 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 would 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 would reveal information about the evolution and state of the Earth’s crust.
The Proposed NISAR Mission: All-Weather Day and Night Imaging
The NASA-ISRO SAR (NISAR) Mission would acquire radar images of surface changes globally. Rapid sampling over the life of the mission would allow for understanding Earth processes and change.
Radar penetrates clouds and operates day and night. It produces images that are
