NISAR satellite launch marks new phase in NASA-ISRO global earth observation cooperation
The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite was launched by GSLV-F16 from Sriharikota, culminating a decade-long bilateral effort. This 2.8-tonne observatory combines NASA's L-band radar with ISRO's S-band radar, enabling precise detection of surface changes, ground deformation, glacier flow, biomass, land use changes, and sea ice dynamics. NISAR's broad science agenda includes mapping mangrove extent, urban subsidence, and crop-soil interactions, with its data supporting the Sendai Framework on disaster risk reduction and refining IPCC models. The mission signifies India's growing capability in high-value hardware and international space cooperation.
Key Points
