ISRO will launch the joint NASA–ISRO Synthetic Aperture Radar (NISAR) satellite on July 30, 2025, using the GSLV-F16 rocket from Sriharikota. Weighing around 2,393 kg, NISAR will be placed in a 743 km Sun-synchronous orbit. This first-of-its-kind collaboration combines NASA’s L-band and ISRO’s S-band radars to capture high-resolution, all-weather images of Earth every 12 days. Designed to monitor changes in land, vegetation, glaciers, and disasters, NISAR represents a major leap in climate and disaster research. After a 90-day calibration phase, it will begin scientific operations, marking a $1.5 billion milestone in Indo-US space cooperation.
