Stunning Light and Looming Darkness

July 11, 2013
Release Date: July 5, 2013 Topics: Color Images, Crater Rays, Named Craters, WAC Date acquired: May 08, 2013 Image Mission Elapsed Time (MET): 10356510, 10356502, 10356498 Image ID: 4029993, 4029991, 4029990 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: 2.04° Center Longitude: 158.8° E Resolution: 440 meters/pixel Scale: Raden Saleh crater is about 23 km (14 miles) in diameter Incidence Angle: 21.5° Emission Angle: 38.1° Phase Angle: 59.6° Of Interest: This color image shows Raden Saleh crater in a new light. The crater's bright ejecta rays are superimposed on the surrounding terrain, including a patch of dark low reflectance material (LRM). In the lower right corner, rays from Qi Baishi crater are 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.
