The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, a landmark Indo-US collaboration, is set to become operational on November 7, 2025. Launched on July 30 from Satish Dhawan Space Centre using ISRO’s GSLV rocket, the 2,400 kg satellite features advanced dual-band radar instruments: NASA’s L-band and ISRO’s S-band. These sensors enable all-weather, day-night monitoring of the Earth’s land and ice surfaces every 12 days, facilitating precise disaster management, agricultural planning, glacier and water resource monitoring, and climate change studies. This mission marks India’s emergence as a key player in global radar-based Earth observation, showcasing indigenous space capabilities while strengthening strategic ties with the US. Beyond scientific benefits, NISAR’s data is expected to aid India’s border surveillance, particularly along Himalayan frontiers, enhancing security insights amidst ongoing regional geopolitical dynamics. The operational declaration follows successful calibration and data validation by both space agencies. This milestone also exemplifies expanding Indo-US space cooperation post-launch, affirming India’s strategic technological advancements.
