NASA\u2019s Jet Propulsion Laboratory used radar data taken by ESA\u2019s Sentinel-1A satellite before and after the 2015 eruption of the Calbuco volcano in Chile to create this inter-ferogram showing land deformation. The color bands west of the volcano indicate land sinking. NISAR will produce similar images.<\/div>\n

A SAR image \u2014 like ones NISAR will produce \u2014 shows land cover on Mount Okmok on Alaska\u2019s Umnak Island. Created with data taken in August 2011 by NASA\u2019s UAVSAR instrument, it is an example of polarimetry, which measures return waves\u2019 orientation relative to that of transmitted signals.<\/div>\n

Data from NASA\u2019s Magellan spacecraft, which launched in 1989, was used to create this image of Crater Isabella, a 108-mile-wide (175-kilometer-wide) impact crater on Venus\u2019 surface. NISAR will use the same basic SAR principles to measure properties and characteristics of Earth\u2019s solid surfaces.<\/div>\n
