Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
Simple cylindrical projection
Mercury's diameter is 4880 kilometers (3030 miles)
This colorful view of Mercury is similar to that used to generate this movie [23MB
] of Mercury as a spinning globe, and these two individual views (centered at 140°E
) of the innermost planet. The enhanced color view is overlaid on the global monochrome base map, which is available for download here
The enhanced color 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. This specific color combination places the second principal component in the red channel, the first principal component in the green channel, and the ratio of the 430 nm/1000 nm filters in the blue channel.
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. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
