NISAR stands for NASA-ISRO Synthetic Aperture Radar, a joint Earth observation mission between the American space agency NASA and the Indian Space Research Organisation (ISRO). This satellite is designed to use advanced synthetic aperture radar technology operating in dual bands—L-band and S-band—to study Earth's surface changes with high precision. It will monitor natural hazards, deformation, and environmental shifts like glacier movements and forest biomass changes. The collaboration exemplifies the growing partnership between India and the U.S. in space science and technology, and marks their first joint satellite development and launch.
