QuoteThe new Mercury photo shows a region around the south pole of Mercury. A 53-mile (85-kilometer) wide crater called Debussy clearly stands out in the upper right of the image, with bright rays emanating from its center. [More photos of Mercury from Messenger]
A smaller crater called Matabei, which is 15 miles (24 km) wide and is known for its "unusual dark rays," is also visible in the image to the west of the Debussy crater, mission managers explained.
The new Mercury photo was posted to the Messenger mission website managed by the Johns Hopkins University Applied Physics Laboratory, which is overseeing the flight for NASA. 
The photo is the first of 363 snapshots Messenger took during six hours of observations around Mercury. The images are expected to cover previously unseen areas of Mercury, terrain that was missed by Messenger during three previous flybys before it entered orbit.
Messenger arrived at Mercury on March 17, more than 6 1/2 years after its launch from Earth.
The spacecraft paused in its Mercury photo reconnaissance work just long enough to beam the new images back to Earth, mission managers said.

Amazing!
One can only imagine what Earth had gone through in the beginning.
