Luna, Earth's only moon, was first visited by modern humanity in 1969 and colonized by 2080. In 2362, the first extrasolar colony vessel—the Odyssey—was launched from a mooring platform over Luna, leaving for the planet Reach in the Epsilon Eridani system and kicking off the Domus Diaspora. Even following these colonization efforts, Luna has remained an extremely important colony within the human sphere. The UNSC Navy's prestigious Luna OCS Academy is located in Mare Nubium and ONI maintains a facility in Daedalus Crater.
