Caption:
The crater Nobokov exhibits a rugged basin ring and degraded crater rim. The inset color image suggests that the basin floor may be of a slightly different composition than the surrounding material. The inset color image is a composite of the MDIS Wide Angle Camera filters with the 1000-nm filter depicted in red, the 750-nm filter depicted in green, and the 430-nm filter depicted in blue. The blueish hue in the color image reveals that Nabokov has a slightly shallower spectral slope than many of the younger volcanic terrains on Mercury.
This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

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.
For information regarding the use of images, see the MESSENGER image use policy .
