The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft launched on June 18, 2009. It operates in a low polar orbit around the Moon and is mapping the lunar surface in unprecedented detail, measuring topography, radiation, temperature, and resources. Its data help identify safe landing sites, locate water ice in shadowed regions, and support future human and robotic exploration.
