Orbiting Messenger Sends Back Surprising Data on Mercury

Hosted by

NASA's Messenger is the first space craft to orbit the planet Mercury, where it's been circling for 88 days. Some previous theories are being confirmed but many others are ending up in the "dustbin of science." Messenger left Earth in 2004, and it's now mapping the surface of Mercury in unprecedented detail, providing much new — often puzzling — information. Pete Spotts is covering the story for the Christian Science Monitor.
