The Caloris basin on Mercury is one of the youngest large impact basins in the Solar System, and MESSENGER images are enabling scientists to study it in ways not previously possible. This image, acquired by the Narrow Angle Camera, (NAC), of the Mercury Dual Imaging System, (MDIS), was taken on January 14, 2008, and shows an area that is about 280 kilometers across, (about 170 miles), on the floor of the basin. Bright rays from a young impact crater extend into the image from the top right corner. This bright-rayed crater is located slightly left of the center of the basin and is easily spotted on the previously released image that shows the entire Caloris basin.
