NISAR
MISSION CONCEPT
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 Concept

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
detailed enough to see local changes, and has broad enough coverage to measure regional trends. The proposed NASA-ISRO Synthetic Aperture Radar (NISAR) mission, a collaboration between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organization (ISRO), would acquire images of ecosystem changes globally. Rapid sampling over the lifetime of the mission would allow for understanding disturbance, degradation, and response. NISAR’s unprecedented coverage in space and time would 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 would reveal information that would allow us to better manage resources and prepare for and cope with global change.
