From Bengaluru, India's space agency has opened a new chapter in planetary stewardship: radar imagery from the joint NASA-ISRO NISAR satellite — the first spacecraft to carry dual-frequency radar — is now freely available to anyone through ISRO's Bhoonidhi portal. Launched last July and orbiting 747 kilometers above us, the satellite sees through clouds and darkness alike, returning to the same patch of Earth every 12 days to build a living record of glaciers retreating, floods spreading, and coastlines shifting. This release is less a technical announcement than a quiet act of democratization
