Date acquired: August 09, 2011
Image Mission Elapsed Time (MET): 221362822
Image ID: 609826
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: -77.79°
Center Longitude: 300.7° E
Resolution: The surface near the center of the image is approximately 1600 meters/pixel
Scale: Mercury's radius is 2,440 kilometers (1,520 miles)

Of Interest: This dramatic view was captured as the spacecraft's highly elliptical orbit positioned MESSENGER high above Mercury's southern hemisphere. The large basin with the smooth floor near the center right portion of the image is Pushkin.

This image was acquired as part of MDIS's limb imaging campaign. Once per week, MDIS captures images of Mercury's limb, with an emphasis on imaging the southern hemisphere limb. These limb images provide information about Mercury's shape and complement measurements of topography made by the Mercury Laser Altimeter (MLA) of Mercury's 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. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
