Impact craters feature prominently in new images from NASA's Lunar Reconnaissance Orbiter: Older craters have softened edges, while younger craters appear crisp.
The ancient Anaxagoras A crater, seen above in a picture released July 2, 2009, is located near the moon's north pole. The crater's old age is apparent when its soft rim is compared to the sharp outlines of younger, smaller craters that dot its edges.
Although the new images are impressive in their own right, Robinson said, their main message is that the LRO's camera is ready for prime time.
