Mountains of Darkness

November 2, 2012
Date acquired: August 27, 2012 Image Mission Elapsed Time (MET): 254597521 Image ID: 2471477 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 72.71° Center Longitude: 67.90° E Resolution: 17 meters/pixel Scale: The vertical field of view in this image is approx. 20 km (13 mi.) across Incidence Angle: 83.4° Emission Angle: 47.6° Phase Angle: 130.9° Of Interest: This dramatic image shows the central peak of the Stieglitz impact crater, located high on Mercury's northern hemisphere. The fresh appearance of its ejecta deposit suggests that Stieglitz is a relatively young crater. Intriguingly, this crater also hosts radar bright materials. 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.
