Flying V

September 4, 2013
Date acquired: October 14, 2011 Image Mission Elapsed Time (MET): 227092494 Image ID: 884412 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filter: 7 (748 nanometers) Center Latitude: 79.09° Center Longitude: 352.7° E Resolution: 140 meters/pixel Scale: The "V" is about 59 km (37 mi.) long Incidence Angle: 84.1° Emission Angle: 28.2° Phase Angle: 112.3° Of Interest: This view of a location within Mercury's northern volcanic plains includes a set of wrinkle ridges that form a "V" shape. This image was acquired as part of MDIS's high-resolution surface morphology base map. The surface morphology base map covers more than 99% of Mercury's surface with an average resolution of 200 meters/pixel. Images acquired for the surface morphology base map typically are obtained at off-vertical Sun angles (i.e., high incidence angles) and have visible shadows so as to reveal clearly the topographic form of geologic features. 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.
