NASA’s Messenger spacecraft snapped the new Mercury photo today (March 29) at 5:20 a.m. EDT (0920 GMT). The photo shows the stark gray landscape of southern Mercury, a view that is dominated by a huge impact crater. [See the first photo of Mercury from orbit]
“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. [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.
