Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
9, 7, 6 (996, 748, 433 nanometers) in red, green, and blue
Sander crater is about 51 km (31.7 miles) in diameter
Today's image features a stunning view of two complex craters
within the Caloris
basin. The floor of Sander
crater is covered with bright hollows
, while Munch
crater stands out due to its low-reflectance
This image was acquired as a high-resolution targeted color observation. Targeted color observations are images of a small area on Mercury's surface at resolutions higher than the 1-kilometer/pixel 8-color base map. During MESSENGER's one-year primary mission, hundreds of targeted color observations were obtained. During MESSENGER's extended mission, high-resolution targeted color observations are more rare, as the 3-color base map covered Mercury's northern hemisphere with the highest-resolution color images that are possible.
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.
