Bartok's Blues

June 12, 2014
Release Date: June 11, 2014 Topics: Color Images, Crater Rays, Named Craters, WAC Date acquired: November 12, 2013 Image Mission Elapsed Time (MET): 26540775, 26540771, 26540769 Image ID: 5180966, 5180964, 5180963 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filters: 9, 7, 6 (996, 748, 433 nanometers) in red, green, and blue Center Latitude: -29.48° Center Longitude: 224.9° E Resolution: 1350 meters/pixel Scale: This image's central crater has a diameter of approximately 117 km (73 miles) Incidence Angle: 51.4° Emission Angle: 27.9° Phase Angle: 79.0° Of Interest: Bartok, a large complex crater in Mercury's southern hemisphere, is located in the center of the frame. In this colored image, Bartok's central peak appears to be blue and is darker than the surrounding surface. This suggests that the central uplift is composed of material that has different properties than the surrounding terrain, providing clues to the geologic history of the region. To the southwest of Bartok, a young crater with stunning rays is also visible. This image was acquired as a targeted high-resolution 11-color image set. Acquiring 11-color targets is a new campaign that began in March 2013 and that utilizes all of the WAC's 11 narrow-band color filters. Because of the large data volume involved, only features of special scientific interest are targeted for imaging in all 11 colors. 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. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
