NASA probe reaches Mercury

"Despite its proximity to Earth, the planet Mercury has for decades been comparatively unexplored," said Sean Solomon, Messenger principal investigator.

"For the first time in history, a scientific observatory is in orbit about our solar system's innermost planet," he said. "Mercury's secrets, and the implications they hold for the formation and evolution of Earth-like planets, are about to be revealed."

Kudos for the folks on the Messenger mission for achieving orbit. Hopefully we can find out more about the elusive inner planet.
