India successfully launched the NISAR satellite—a $1.5 billion joint mission between ISRO and NASA—on July 30 from Sriharikota. NISAR (NASA-ISRO Synthetic Aperture Radar) is the world’s first Earth-mapping satellite using dual-frequency radar, capable of detecting Earth’s slightest shifts and changes every 12 days. Weighing 2,393 kg, it will orbit the planet every 97 minutes, aiding global disaster response, glacier tracking, and climate monitoring. The mission, a decade-long collaboration, marks a major leap in space-tech and environmental science. With near real-time, free data, India strengthens its leadership in global climate action and scientific cooperation.
