NASA-NISAR satellite to monitor Earth's changing surface for disaster management
The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is a joint mission designed to observe Earth's changing surface with high detail. Utilizing L-band and S-band radars, it will provide data every 12 days to monitor ecosystems, ice sheets, farmlands, and volcanoes. NISAR's mission is crucial for understanding natural hazards like earthquakes, tsunamis, and volcanic eruptions, and for tracking changes in land surface, groundwater, and forest cover. The data will significantly aid disaster management, climate change studies, and resource management globally, offering a "Smart Way to Succeed" in various administrative applications and environmental monitoring efforts.
