Caption:

The first image taken following MESSENGER's closest distance to Mercury ( PIA11352 ) during the mission's recent flyby was a Wide Angle Camera (WAC) image. The image shown here is the first NAC image acquired after closest approach, and since the resolution of the NAC is a factor of seven higher than that of the WAC, this image is the highest-resolution image obtained during MESSENGER's second Mercury flyby. The image was taken near local dawn, so the shadows are long and many features are shrouded in darkness. The right side of this image overlaps with the left side of the previously released close-up view of Machaut crater ( PIA11249 ), which was taken just five seconds later than this image. This portion of Mercury's surface is heavily cratered, with small craters visible down to the limits of even this highest-resolution image.
