Release Date: April 29, 2013 Topics: NAC, Named Craters Date acquired: April 22, 2013 Image Mission Elapsed Time (MET): 8944037 Image ID: 3929664 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 36.35° N Center Longitude: 232.6° E Resolution: 24 meters/pixel Scale: The diagonal of this image is approximately 36 km (22 mi.) across. Incidence Angle: 43.6° Emission Angle: 12.7° Phase Angle: 56.3° Of Interest: A portion of the rim of Degas crater is visible towards the top of this image. The hummocky texture of the interior crater wall is due to the slumping and downslope movement of material soon after the crater formed. This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week. 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.
