On July 30, 2025, the joint NASA‑ISRO NISAR (NASA‑ISRO Synthetic Aperture Radar) satellite launched from Satish Dhawan Space Centre aboard GSLV‑F16 . The $1.5 billion mission features dual-frequency radar (NASA’s L‑band and ISRO’s S‑band) capable of detecting surface changes as small as 1 cm, through clouds and darkness, revisiting each location every 12 days . NISAR will revolutionize monitoring of ice‑sheet collapse, land deformation, earthquakes, tsunamis, and ecosystem shifts, aiding disaster response, climate science, and infrastructure planning globally . As the first Earth‑observation mission co‑developed by NASA and ISRO, it marks a milestone in international collaboration and space innovation. (PC: NASA)
