The Indian Space Research Organisation (Isro) has completed the development of a radar capable of producing extremely high-resolution images for a joint earth observation satellite mission with the National Aeronautics and Space Administration (Nasa). The Nasa-Isro Synthetic Aperture Radar (NISAR) is a collaboration between the Indian and US space agencies for a dual-frequency L and S-band SAR for earth observation. The S-Band SAR was shipped from the Space Applications Centre at Ahmedabad in Gujarat to the jet propulsion laboratory (JPL) at Pasadena in Los Angeles County, California, to be integrated with Nasa’s L-Bank SAR payload. NISAR is estimated to be the world’s most expensive Earth imaging satellite. The total cost of the project includes Isro’s work share cost of about Rs 788 crore and about $808 million of JPL’s.
