On the Edge of Goethe

August 21, 2013
Date acquired: February 10, 2013 Image Mission Elapsed Time (MET): 2778942, 2778934, 2778938 Image ID: 3491366, 3491364, 3491365 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: 82.92° Center Longitude: 286.5° E Resolution: 86 meters/pixel Scale: The small crater in the center of the image is 2.7 km (1.7 miles) in diameter. Incidence Angle: 88.0° Emission Angle: 17.5° Phase Angle: 87.8° Of Interest: This view shows the edge of the Goethe Basin. The margins of the basin interior are marked by wrinkle ridges. Part of one such ridge is shown in this image. The scene also includes small secondary crater chains on the smooth plains that fill the basin, and the hummocky terrain outside of the basin. This image was acquired as part of MDIS's high-resolution 3-color imaging campaign. The map produced from this campaign complements the 8-color base map (at an average resolution of 1 km/pixel) acquired during MESSENGER's primary mission by imaging Mercury's surface in a subset of the color filters at the highest resolution possible. The three narrow-band color filters are centered at wavelengths of 430 nm, 750 nm, and 1000 nm, and image resolutions generally range from 100 to 400 meters/pixel in the northern hemisphere. 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.
