About
The NASA-ISRO Synthetic Aperture Radar (NISAR) is an Earth observation satellite (EOS) equipped with dual-frequency synthetic-aperture radar (SAR) jointly developed by NASA and ISRO, launched by ISRO on 30 July 2025 from Satish Dhawan Space Centre. It is the first radar imaging satellite to use dual frequencies. It is being used for remote sensing, to observe and understand natural processes on Earth. With a total cost estimated at US$1.5 billion, NISAR is likely to be the world's most expensive Earth-imaging satellite.
