NASA Spacecraft Snaps First Photo of Mercury

The first spacecraft ever to circle Mercury has beamed home the first-ever photo taken of the small rocky planet from orbit, showing a stark landscape peppered with craters. 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.

"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 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.
