Image Mission Elapsed Time (MET):
Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
The large crater at the center of the image is approximately 60 km (37 mi.) in diameter.
North is to the right in this image.
Take a look at Adventure Rupes in 3D! Adventure is a lobate scarp
, formed when one block of crust was thrust forward over another. This scarp cuts across
a degraded, ~60-km-diameter (37-mi.-diameter) crater. By measuring the change in the shape of a once-circular crater, scientists can estimate the amount of horizontal shortening across the scarp.
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.
