Image Mission Elapsed Time (MET):
Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
7 (748 nanometers)
The largest crater in this image is approximately 120 km (75 mi.) in diameter.
The large, unnamed crater in this image shares part of its wall with the younger, smaller (42 km/26 mi) unnamed crater that formed inside of it. The floor and rim of the smaller crater contains many hollows
, which are difficult to make out in this high-incidence-angle image.
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, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.
