        ShadowCam is a Time Delay Integration(TDI) pushbroom imager (1.7 m/pixel) on the Korea Pathfinder Lunar Orbiter (KPLO).
        The primary mission is to map albedo patterns in PSRs and interpret their nature, investigate the origin of anomalous radar
        signatures associated with some polar craters, document and interpret temporal changes of PSR albedo units, and provide hazard and
        trafficability information within PSRs for future landed elements.
