First rock from the Sun: this is one of the highest-resolution views ever obtained of Mercury's surface.
It shows an area of complicated geology where the rims of two impact craters intersect. We can see the floor of a smaller crater in the upper part of the image, and the steep walls and terraces of a larger crater in the lower part of the image.
The scale of the scene is about 7.5 miles (12 km) diagonally across the frame. The image was acquired on 30 April 2012 by NASA's MESSENGER spacecraft.
