This image, taken with the Narrow Angle Camera (NAC), gives us a close-up look at the crater Kalidasa, named for the renowned classical Sanskrit writer Kālidāsa. It is likely that after Kalidasa crater formed, a smaller impact created a second crater and destroyed part of Kalidasa's central peak. The low elevation areas in both craters were subsequently flooded with volcanic material, creating smooth plains on which light cratering has continued.

This image was acquired as part of MDIS's high-resolution stereo base map. The stereo base map is used in combination with the surface morphology base map to create high-resolution stereo views of Mercury's surface, with an average resolution of 250 meters/pixel (0.16 miles/pixel or 820 feet/pixel) or better. During MESSENGER's one-year mission, the surface morphology base map is acquired during the first 176 days, and the second 176 days are used to acquire the complementary stereo base map, which includes the image here.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
