Over time, the surface of the Moon fractures and buckles as it cools and shrinks, resulting in spectacular landforms. Stereo images provided by the LROC NAC allow a detailed look at these amazing features; view is to the east, foreground to background distance is ~3 km [NASA/GSFC/Arizona State University].

With the Sun exactly overhead, the illumination conditions and viewing angles of the LROC WAC create a rainbow effect in this image. 689 nm filter in red, 643 nm filter in green, and 604 nm filter in blue, from image M109168446C. Scene from north to south covers ~120 km [NASA/GSFC/Arizona State University].

Fig. 1: A lesser-known impact basin, Freundlich-Sharonov, is visible in this Digital Terrain Model (DTM) made from LROC WAC stereo images, and darker shades represent lower elevations than brighter shades. The diameter of the orange-colored ring is 595 km. DTM images like these allow scientists to inventory and study the morphologies of lunar basins [NASA/GSFC/Arizona State University/DLR].

A Digital Terrain Model ("DTM") of the large Orientale Basin (1100 km diameter), located on the western hemisphere of the Moon, produced from stereo images obtained by LROC's Wide-Angle Camera. The image shows the hill-shaded, color-coded DTM with heights varying from approx. -4,700 meters to 9,400 meters. The small white boxes are areas without WAC coverage [NASA/GSFC/Arizona State University/ DLR].

Full resolution detail from one of the first LROC NAC images. At this scale and lighting, impact craters dominate the landscape. Two general types of impact craters are readily identifiable. Solitary craters which most likely represent a single impact event, and clusters or chains of small, fresh craters produced by the impact of lunar material excavated by a larger impact. Image width is 1400 meters, north is down [NASA/GSFC/Arizona State University].
