On July 30, 2025, ISRO launched the $1.5 billion NISAR satellite aboard GSLV-F16, making it the world’s most expensive Earth-imaging satellite. Jointly developed with NASA, NISAR combines L-band (NASA) and S-band (ISRO) radar, becoming the first satellite to use dual-band synthetic aperture radar. It will orbit in a sun-synchronous path, scanning Earth every 12 days to monitor land changes, glacier melt, forest loss, and disasters with centimeter-level precision. With a five-year mission life, NISAR will significantly aid climate research, environmental monitoring, and disaster response across the globe.
