Just the Peaks

February 13, 2013
Date acquired: December 15, 2012 Image Mission Elapsed Time (MET): 264103036 Image ID: 3147414 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 76.84° Center Longitude: 139.9° E Resolution: 12 meters/pixel Scale: This scene is 13 km (8 mi.) across Incidence Angle: 77.0° Emission Angle: 12.6° Phase Angle: 71.2° Of Interest: The central peaks of an unnamed 38-km crater fill this scene. The sun is coming from the left side of the frame, so that the peaks cast their shadows to the right. North is to the right in this image. 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. 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, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.
