LROC NAC Image -- Top Detail (IMAGE) Arizona State University Caption This full resolution detail is from one of the first images taken by a Narrow Angle Camera, part of the Lunar Reconnaissance Orbiter Camera imaging system. At this scale and lighting, impact craters dominate the landscape. Visible are two general types of impact craters: 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 1,400 meters (0.87 miles), north is down.
