Members of the integration and test team from NASA’s Jet Propulsion Laboratory and the Indian Space Research Organization (ISRO) pose with NISAR’s S-synthetic aperture radar (S-SAR) instrument in a clean room at JPL in Southern California. The 12 cm wavelength S-SAR, supplied by ISRO, will be used to produce data about science areas of interest such as coastal waters and shorelines, ocean winds, and geology in India. The S-band will be used there because unlike NISAR's L-band radar, its signal is less sensitive to ionospheric disturbances.
