Along a Scarp

June 10, 2014
Release Date: June 9, 2014 Topics: NAC, Scarps, Tectonics Date acquired: June 24, 2013 Image Mission Elapsed Time (MET): 14415278 Image ID: 4318782 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 19.56° Center Longitude: 45.40° E Resolution: 35 meters/pixel Scale: The crater in the upper center of this image has a diameter of approximately 6.6 km (4.1 miles) Incidence Angle: 61.4° Emission Angle: 31.1° Phase Angle: 92.2° Of Interest: Today's image features several of Mercury's simple craters. The morphology of simple craters is characterized by the crater's distinct bowl shape and crisp rim. The largest simple crater in this view is positioned just above a scarp. Scarps are common topographic features on Mercury that form as one block of the planet's crust is thrusted forward over another block. 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.
