A What happened
The National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO) have introduced the first images from NISAR, the most advanced Earth radar satellite to date. Launched on July 30, 2025, NISAR is designed to monitor Earth's changes over time, providing crucial data for scientists and decision-makers. The satellite employs two radar systems, L-band and S-band, to capture detailed images of the Earth's surface, including forests, farmland, and ice levels. Initial test images reveal impressive detail, showcasing the satellite's capability to identify various land features and conditions. The collaboration between NASA and ISRO represents a significant achievement in space technology, with expectations high for the upcoming full science phase set to commence in November 2025. The insights gained from NISAR are anticipated to extend beyond Earth science, potentially informing studies of other planets.
