February 26, 2013
Release Date: February 21, 2013 Topics: Named Craters, Polar, WAC Date acquired: January 07, 2013 Image Mission Elapsed Time (MET): 266090610 Image ID: 3288616 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filter: 2 (700 nanometers) Center Latitude: 84.90° Center Longitude: 68.75° E Resolution: 79 meters/pixel Scale: Prokofiev has a diameter of 112 kilometers (70 miles). Incidence Angle: 84.9° Emission Angle: 6.1° Phase Angle: 78.8° Of Interest: Prokofiev, named in August 2012 for the Russian composer, is the largest crater in Mercury's north polar region to host radar-bright material. MESSENGER has found evidence that within the cold, dark, permanently shadowed regions of Prokofiev, water ice is exposed on the surface. 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.
