NASA-ISRO's NISAR sends first radar images of Earth's surface; reveals exceptional details of land, forests and agriculture

NASA and ISRO have released the first radar images captured by their joint Earth-observing satellite, NISAR (NASA-ISRO Synthetic Aperture Radar). Launched on July 30, 2025, the satellite carries advanced L-band and S-band radar systems, designed to provide unprecedented insight into Earth’s dynamic surface. The initial images, captured in August, reveal remarkable detail, from dense forests and wetlands to farmland patterns and urban areas, highlighting the potential for monitoring ecosystems, agriculture, and natural disasters. NISAR’s success represents a milestone in international collaboration, combining NASA and ISRO expertise to advance science, technology, and global understanding of Earth’s changing environment. The NISAR satellite is the first to carry both L-band and S-ba
