Aksakov crater is 173.6 km (108 mi.) in diameter.
Today's image features a color view of the peak-ringed
crater Aksakov. The inner ring of Aksakov is superimposed by another crater
. Both the central peak
of this smaller crater and one of the northeastern massifs of the inner peak ring have small areas of hollows
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. In the mission's more than three years of orbital operations, MESSENGER has acquired over 250,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
