[NASA Press Release - 15.09.2010]
NASA's Lunar Reconnaissance Orbiter, or LRO, will complete the exploration phase of its mission on Sept. 16, after a number of successes that transformed our understanding of Earth's nearest neighbor.

LRO completed a one-year exploration mission in a polar orbit approximately 31 miles above the moon's surface. It produced a comprehensive map of the lunar surface in unprecedented detail; searched for resources and safe landing sites for potential future missions to the moon; and measured lunar temperatures and radiation levels.
