For the past two years, NASA's Lunar Reconnaissance Orbiter (LRO) has been orbiting the Moon, gathering data that will help astronauts prepare for long-duration expeditions to the lunar surface, and eventually push further into the "infinite frontier of space." (Read more about the big picture plan here.)
As part of this mission, the LRO has traveled approximately 50 kilometers (31 miles) above the Moon, creating a 3-D map of the lunar surface. And now we're receiving images that show us the Moon in unprecedented detail and focus. The valleys. The craters. The desolate surface. They're all there, as never seen before, in HD.
