MESSENGER departs Mercury
This approximately true color view of Mercury was created by manipulation of the color space of the false-color official release from the MESSENGER team. The image was captured as MESSENGER departed its first flyby of Mercury on January 14, 2008. Caloris is a large bright basin in the top half of the image. Tolstoj is a dark-ringed impact structure, highly foreshortened at about 4:00 on the limb.
