Mountains in the Distance

February 26, 2013
Release Date: February 19, 2013 Topics: Caloris, Limb Images, NAC Date acquired: December 18, 2012 Image Mission Elapsed Time (MET): 264299214 Image ID: 3161641 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 6° Center Longitude: 149° E Additional Location Information: The mountain on the horizon on the left side of the image is at roughly 13°, 152° E Scale: The bottom of this image is about 210 kilometers (130 miles) across. Of Interest: This striking view is located near the rim of the large Caloris basin. The rim of Caloris is marked by hills and mountains, some of which can be seen in the distance in this image. This image was acquired as part of MDIS's limb imaging campaign. Once per week, MDIS captures images of Mercury's limb, with an emphasis on imaging the southern hemisphere limb. These limb images provide information about Mercury's shape and complement measurements of topography made by the Mercury Laser Altimeter (MLA) of Mercury's northern hemisphere. 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.
