NASA-ISRO SAR Mission (NISAR)

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is designed to provide a detailed view of the Earth to observe and measure some of the planet's most complex processes, including ecosystem disturbances, ice-sheet collapse, natural hazards, sea level rise, and groundwater issues. Its radar, the first of its kind in space, will systematically map Earth, measuring changes of our planet’s surface as small as a centimeter.
