Image Mission Elapsed Time (MET):
Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
The large graben going from left to right across the scene is approximately 40 km (25 mi.) long.
North is to the left in this image.
The interior of the Caloris basin
has undergone complex tectonic modification
. The prominent graben
towards the bottom of the image lies just south of the crater Apollodorous
near the center of Caloris
. It is one of the largest graben in Pantheon Fosse
This image pair was acquired as a targeted set of stereo images. Targeted stereo observations are acquired at resolutions much higher than that of the 200-meter/pixel stereo base map. These targets acquired with the NAC enable the detailed topography of Mercury's surface to be determined for a local area of interest.
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.
