Launched on July 30, 2025 via ISRO’s GSLV‑F16 from Sriharikota, the NASA‑ISRO Synthetic Aperture Radar (NISAR)—a $1.5 billion mission—is the world’s first radar satellite to use dual-frequency sensors (NASA’s L‑band & ISRO’s S‑band). The “two‑eyed” payload enables it to map nearly all land and ice surfaces every 12 days, detecting changes down to a centimeter, day or night, through clouds and vegetation . Over its planned three‑year mission, NISAR will revolutionize monitoring of earthquakes, glacier melt, deforestation, landslides, infrastructure stability, agricultural patterns and more—delivering open-access data to scientists, policymakers, and disaster responders worldwide.
