Caption:
Though many craters are visible in this color view of Mercury's limb , Degas gets noticed. Located near the center of the image, the distinctive blue color of the low-reflectance material associated with Degas contrasts with the surrounding terrain and neighboring craters. View these previously posted web images to see Degas in high-resolution with the Narrow Angle Camera (NAC) or in high-resolution color with the WAC.
This image was acquired as a targeted observation that occurred simultaneously with a measurement by the Mercury Atmospheric and Surface Composition Spectrometer (MASCS). Targeted observations that involve both MDIS and MASCS facilitate combining the data from both instruments to understand the color and reflectance of small-scale geologic features on Mercury's surface.

Background Info:
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 acquired 88,746 images and extensive other data sets. MESSENGER is now in a year-long extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.
These images are from MESSENGER, a NASA Discovery mission to conduct the first orbital study of the innermost planet, Mercury. For information regarding the use of images, see the MESSENGER image use policy .
