Image Mission Elapsed Time (MET):
Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
7 (748 nanometers)
The scene is about 175 km (109 mi.) across
North is up in this image.
Today's image features a sinuous lobate scarp
that snakes across the floor of Sinan crater. Sinan is an older, degraded impact crater, 134 km in diameter. Sinan's rim and peak ring mountains
have been worn down by impacts, and the basin has been profoundly modified by several large, younger impacts. And small hollows
dot parts of the northern rim, lobate scarp, peak ring, and floor.
Joseph Sinan was a Turkish architect who lived from about 1490 to 1588 CE. He was a chief architect to several Ottoman sultans. He and his apprentices designed a number of famous mosques and other buildings.
This image was acquired as part of MDIS's high-resolution stereo imaging campaign. Images from the stereo imaging campaign are used in combination with the surface morphology base map or the albedo base map to create high-resolution stereo views of Mercury's surface, with an average resolution of 200 meters/pixel. Viewing the surface under the same Sun illumination conditions but from two or more viewing angles enables information about the small-scale topography of Mercury's surface to be obtained.
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. In the mission's more than three years of orbital operations, MESSENGER has acquired over 250,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
