NASA | LRO: Mapping the Future

The Lunar Reconnaissance Orbiter (LRO) is the first mission in NASA's planned return to the moon. LRO is an unmanned mission to create the comprehensive atlas of the moon's features and resources necessary to design all future lunar exploration efforts. LRO focuses on the selection of safe landing sites, identification of lunar resources and the study of how lunar radiation will affect humans.
