Mission

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.

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.

The Level 1 Science Requirements describe NISAR's scientific measurements. These are developed with greater specificity at Level 2.

NASA selected a Science Definition Team (SDT) in 2012 to work with the NISAR project to develop science requirements. In March 2015, a solicitation for recompetition of this team was announced. Plans for SDT activities in the upcoming project phase are described here.
