Using advanced radar imaging that will provide an unprecedented, detailed view of Earth, the NASA-ISRO Synthetic Aperture Radar, or NISAR, satellite is designed to observe and take measurements of some of the planet's most complex processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides.more
Data collected from NISAR will reveal information about the evolution and state of Earth's crust, help scientists better understand our planet's processes and changing climate, and aid future resource and hazard management. The mission is a partnership between NASA and the Indian Space Research Organization.
NASA selected a Science Definition Team in 2012 to work with the NISAR project to develop science requirements, and again in 2016 develop calibration and validation plans as well as science product requirements. A pre-launch Science Team was selected in 2019 to implement cal/val activities.
