Bengaluru: March 09, 2021 ISRO has completed development of a Synthetic Aperture Radar (SAR) capable of producing extremely high-resolution images for a joint earth observation satellite mission with the US space agency NASA. NASA-ISRO SAR (NISAR) is a joint collaboration for a dual-frequency L and S-band SAR for earth observation. “NISAR will be the first satellite mission to use two different radar frequencies (L-band and S-band) to measure changes in our planet’s surface less than a centimeter across”, according to NASA (National Aeronautics and Space Administration). NASA and Bengaluru-headquartered ISRO (Indian Space Research Organisation) signed a partnership on September 30, 2014, to collaborate on and launch NISAR. The mission is targeted to launch in early 2022 from ISRO’s Sriharikota spaceport in Andhra Pradesh’s Nellore district, about 100 kms north of Chennai.
