Luna

Luna, often referred to as the Moon, is the only natural satellite of Earth. Luna is home to a large human population and the renowned Luna OCS Academy. Luna houses a number of skyhook defense complexes suspended in its low orbit.

History
Humans began settling on Luna around 2080. Luna has not been heavily terraformed, a result of its low gravity and lack of atmosphere. Instead, the habitats on Luna are sealed from vacuum and interconnected by tubes. By 2492, the governing body of Luna was known as Luna Confederated States, the State of Mare Nubium being one of the said states. The Academy at Mare Nubium, known more generally as the Luna OCS Academy, was located here. Despite its proximity to Earth, Luna was home to some degree of Insurrectionist activity; shortly after 2530, the parents of Michael Crespo died attempting to detonate a bomb attached to a government building on Luna.

During the Battle of Earth in late 2552, Luna's skyhook defense complexes came under attack by the Covenant and were defended by ONI Security personnel. Other Covenant forces attacked Luna's cities to ensure that the UNSC would not be able to launch a sneak attack from their Lunar military bases. Both Luna and Mars got hit particularly hard compared to other colonies in the Sol system, although they both fared better than Earth. The human population centers on the moon survived the Covenant assault relatively intact. Following the Human-Covenant War, Luna was home to the Office of Naval Intelligence vessel, which was deployed to investigate an unknown Forerunner signal from Installation 00 in June 2557.
