Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
Mercury's diameter is 4880 kilometers (3030 miles)
This colorful view of Mercury was produced by using images from the color base map imaging campaign
during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye
, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks
that make up Mercury's surface.
Young crater rays
, extending radially from fresh impact craters, appear light blue or white. Medium- and dark-blue areas are a geologic unit of Mercury's crust known as the "low-reflectance material.html"
, thought to be rich in a dark, opaque mineral. Tan areas are plains
formed by eruption of highly fluid lavas
. The giant Caloris basin
is the large circular tan feature located just to the upper right of center of the 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.
