First launched a decade after its predecessors, Spaceborne Imaging Radar-C was coupled with the German-built X-Band Synthetic Aperture Radar to image Earth in three different wavelengths.
The instrument flew on two separate shuttle missions (STS-59 and STS-68, respectively) and collected data on terrestrial soil moisture content, ocean dynamics, volcanism and tectonic activity, and soil erosion and desertification.
