Date acquired: April 19, 2014
Image Mission Elapsed Time (MET): 40199375, 40199548
Image ID: 6151740, 6151745
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: 28.61°
Center Longitude: 163.1° E
Resolution: 35 meters/pixel
Scale: The large graben going from left to right across the scene is approximately 40 km (25 mi.) long.
Incidence Angle: 36.1°, 36.0°
Emission Angle: 32.7°, 23.7°
Phase Angle: 50.4°, 30.3°
North is to the left in this image.
Of Interest: 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.
