             English: This image of the moon's north polar region was taken by the Lunar Reconnaissance Orbiter Camera, or LROC. One of the primary scientific objectives of LROC is to identify regions of permanent  shadow and near-permanent  illumination. Since the start of the mission, LROC has acquired thousands of Wide Angle Camera images approaching the north pole. From these images, scientists produced this  mosaic, which is composed of 983 images taken over a one month period during northern  summer. This mosaic shows the pole when it is best illuminated, regions that are in shadow are candidates for permanent shadow.
