Peak to Pit

April 22, 2014
Release Date: April 18, 2014 Topics: Albedo Contrasts, Color Images, Named Craters, Volcanism, WAC Date acquired: March 30, 2014 Image Mission Elapsed Time (MET): 38528557, 38528553, 38528551 Image ID: 6032934, 6032932, 6032931 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: 40.7° Center Longitude: 258.9° E Scale: Scarlatti basin is 132 km (82 miles) in diameter Of Interest: The peak-ring basin Scarlatti is seen at the center of this image. While Scarlatti has a typical peak ring in many respects, in the northeast section it transitions to a large (approximately 30 km) pit surrounded by high-reflectance material. This pit may be the site of past explosive volcanic activity. This image was acquired as a targeted 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.
