On July 30, the India-US space collaboration crossed a historic milestone with the successful launch of NISAR, or the NASA-ISRO Synthetic Aperture Radar satellite, a flagship earth observation mission jointly developed by the two nations’ space programmes. It is the first satellite to use radars of two frequencies — the L-band radar by NASA and the S-band radar by ISRO — to continuously monitor the earth’s surface. NISAR is expected to provide unprecedented data on land deformation, ice-sheet dynamics, forest biomass, and natural disasters like earthquakes and floods. With its high-resolution, all-weather, day-night imaging capabilities, NISAR aims to enhance climate resilience, agricultural monitoring, and disaster response. Beyond science, NISAR also holds commercial promise to enable new data services, geospatial analytics, and early-warning systems across sectors such as insurance, infrastructure, and agriculture.
