Caption:

Today's image features an unnamed crater located north of the crater Couperin. Although this crater is only about 6 km (3.7 mi.) in diameter, its bright rays cause it to stand out prominently in regional views of the planet. The rays are particularly distinctive because they fade into the blacker background of low reflectance material .

This image was acquired as a targeted high-resolution 11-color image set. Acquiring 11-color targets is a new campaign that began in March 2013 and that utilizes all of the WAC's 11 narrow-band color filters. Because of the large data volume involved, only features of special scientific interest are targeted for imaging in all 11 colors.

Background Info:

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. MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
