Mercury's craters

By the time Mariner 10 had completed its mission, it had taken more than 7,000 photos of the planet. When Mariner 10 ran out of power in 1975, NASA shut it down. It's believed to be orbiting the sun.MESSENGER was next up to take a closer look. This enhanced color mosaic shows the Munch (from left), Sander and Poe craters, which lie in the northwest portion of the Caloris basin.
