NASA and ISRO Prepare to Launch NISAR Earth-Mapping Satellite

NASA and India’s ISRO are set to launch NISAR, a first-of-its-kind Earth-observing satellite equipped with advanced dual-band radar. Scheduled to lift off no earlier than late July 2025 from Sriharikota, India, NISAR will map nearly all of Earth’s land and ice every 12 days, capturing surface changes with centimeter-level precision. Its L-band and S-band radar systems can penetrate clouds, vegetation, and even soil, making it ideal for monitoring natural disasters like earthquakes, floods, and landslides. NISAR will deliver critical data for climate studies, disaster response, and land-use planning—marking a major step in global Earth science collaboration.
