Center Latitude: 16.51°
Center Longitude: 356.9° E

Phase Angle: 77.9°
Of Interest: Hemingway crater is seen in this color view of Mercury's surface. Hemingway is the 130-km (81-mile) diameter crater with a relatively brown floor and small patch of dark blue in its center. This impact crater has irregular depressions on its floor, which are fairly common in other impact craters and may be due to explosive volcanic events, but the low-reflectance, blue patch on the floor may point to a more complex history.
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.
