Mars

Mars (known as "Edom" to pre-historic Humans and the Forerunners ) is the fourth planet of the Sol System, and one of four terrestrial worlds.

Interplanetary War
Mars was one of the first worlds colonized by humanity settled in 2080. It has since been terraformed into a planet with near-Earth conditions, becoming home to many. Regardless, Mars was the site of a decisive battle during a period where the United Nations organization transitioned into the United Nations Space Command. The UNSC Marines routed the neo-Communist Koslovics on the planet during a series of brutal conflicts in the 2100's before moving on to destroy the Koslovic and Frieden movements throughout the solar system.

Human-Covenant War


Once again, Mars was the site of a large scale engagement called the Battle of Mare Erythraeum, set on the fields of Mare Erythraeum. There, Colonel James Ackerson and his UNSC Defense Forces combated against the Covenant Loyalist Army, commanded by Jiralhanae Chieftain Lepidus, a battle the UNSC also lost.

Trivia

 * Terraforming has transformed the surface of Mars from a former barren and uninhabitable environment into an Earth-like world, despite its still having a red-orange color when seen from space in Halo: Uprising. The Encyclopedia contradicts this, saying that Mars is now "as blue and green as Earth."
 * Mars is the birthplace of Nicole-458, Dutch and Benjamin M. Nunez.
