Just six months after humankind got its first close-up look at the innermost world, one thing is already clear: Mercury, despite its small stature, stands out in the planetary crowd. "Messenger is really revealing a planet that is completely an oddball in every characteristic we can measure," Blewett says. "We don't know what kinds of rocks are on the surface, we don't know what is responsible for its color, its gravity is funny, its magnetic field is funny. It's just an odd planet."

   Have the turquoise hued "curious surface features known as hollows" that line the interior of the Raditladi impact basin on Mercury been color enhanced? Any hypothesis as to what they are?
