Date acquired: June 13, 2011
Image Mission Elapsed Time (MET): 216435840
Image ID: 372310
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: -58.71°
Center Longitude: 161.3° E
Scale: Mercury's radius is approximately 2440 km (1516 mi.)
Of Interest: This fascinating
limb view shows Mercury's southern hemisphere. Highlighted in this image is
Basho, with its dark halo and bright ray system, in the upper left, along with
Han Kan and its prominent rays to the right, near the
terminator.
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.
