The striking topography inside of Angkor Vallis
is believed to have formed by hot, quick-flowing lavas
moving across Mercury's surface. Shown here is a mosaic of four NAC images acquired from a grazing, highly oblique, viewing geometry of the surface. This provides a view that accentuates the height of the landforms within the volcanic valley.
This image was acquired as part of an MDIS campaign to obtain oblique views of Mercury's surface. Such views provide dramatic perspectives on Mercury's landscape.
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.
