It will scan the globe every 12 days over the course of its three-year mission of imaging the Earth’s land, ice sheets and sea ice to give an unprecedented view of the planet. (NASA)

NASA will provide one of the radars for the satellite, a high-rate communication subsystem for science data, GPS receivers and a payload data subsystem. NISAR will be equipped with the largest reflector antenna ever launched by NASA.

S-Band Radar S band radars operate on a wavelength of 8-15 cm and a frequency of 2-4 GHz. Because of the wavelength and frequency, S-band radars are not easily attenuated. This makes them useful for near and far range weather observation.

NISAR's data can help people worldwide better manage natural resources and hazards, as well as providing information for scientists to better understand the effects and pace of climate change. (ISRO)

As the mission continues for years, the data will allow for better understanding of the causes and consequences of land surface changes. It will also add to our understanding of our planet's hard outer layer, called its crust. (NASA)
