The NASA-ISRO NISAR mission, a joint collaboration between the U.S. and India, will provide a detailed view of Earth using its two radar instruments. This mission is significant as it comes amidst deepening scientific ties between the two countries.
The NASA-Indian Space Research Organisation (ISRO) Synthetic Aperture Radar (NISAR) mission is the largest and first truly joint collaboration in space between the U.S. and India. It comes as the two countries deepen their scientific ties more broadly.
The NISAR mission will collect data on tiny changes in Earth's surface, including earthquakes, volcanoes, forests, wetlands, crops, glaciers, and sea ice. The radar instruments can penetrate clouds and collect measurements at night, providing valuable information for climate models and disaster response.
The satellite's two radar instruments give it the ability to observe tiny changes in Earth's surface from earthquakes and volcanoes, as well as shifts in forests, wetlands, crops, glaciers and sea ice. Both radar systems - one built by NASA, the other by ISRO - operate at long wavelengths that can cut through clouds and collect measurements at night. The radar from one of the instruments can penetrate tree canopies and give researchers better estimates of the density of trees, which can be used to track the capture and release of carbon from forests - key information for climate models. NISAR can also detect deformations in Earth's surface with a precision on the order of millimeters for some measurements, says Paul Rosen, a project scientist for the mission at NASA's Jet Propulsion Laboratory.
