Crater on a Ridge

Today's image is one of the highest resolution images MESSENGER has taken to date at only 3 meters per pixel. It features a small ridge with a crater on its crest. The small crater is a simple crater. If you look at the area around the crater, you can spy many craters that are even smaller! As MESSENGER continues passing close to the surface of Mercury, high resolution images such as this one will be taken, allowing scientists (and the public) to see Mercury as it has never been seen before!

This image was acquired as part of the MDIS low-altitude imaging campaign. During MESSENGER's second extended mission, the spacecraft makes a progressively closer approach to Mercury's surface than at any previous point in the mission, enabling the acquisition of high-spatial-resolution data. For spacecraft altitudes below 350 kilometers, NAC images are acquired with pixel scales ranging from 20 meters to as little as 2 meters.
