NASA's MESSENGER Spacecraft snapped the very first picture of Mercury from orbit, showing a desolate landscape peppered with impact craters:
"This image is the first ever obtained from a spacecraft in orbit about the solar system's innermost planet," Messenger mission scientists explained in a statement.
The 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.
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.
