Of Interest: 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.
