The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon on a low 50 km polar mapping orbit. The LRO mission is a precursor to future manned missions to the Moon by NASA. To this end a detailed mapping program will identify safe landing sites, locate potential resources on the Moon, characterize the radiation environment, and demonstrate new technology.
