'''Mars''', also known as '''Sol IV''',<ref name="Halo Channel">''[[Halo Channel]]'': Encyclopedia</ref> known as '''Edom''' in the [[Forerunner]] era,{{Ref/Novel|Id=Cryptum|Halo: Cryptum|Chapter=1}} is the [[planet|fourth planet]] of the [[Sol system]], and one of four terrestrial worlds.

In [[2080]], Mars was the first planet colonized by humanity<ref name="universe"/> in the first wave of [[Human colonies#Interplanetary age|interplanetary colonization]] in the late 21st century.{{Ref/Book|[[Halo Encyclopedia]]|Page=44}} Following its colonization—largely driven by corporations eager to break free from the restrictions of Earth's gravity and international law—Mars quickly became a hub of industry and state-of-the-art scientific research. Advancements were made particularly in the areas of [[nanotechnology|nano-]] and biotechnologies; largely robotics-driven industrial manufacturing and spacecraft construction flourished, the latter most notably in the [[Argyre Planitia]].<ref name="enc42"/> Even before the planet was [[Terraforming|terraformed]], Mars was one of the largest industrial hubs in the [[Sol system]].<ref name="universe"/> With the advances in terraforming technology that accompanied this boom of technological development, Mars was transformed into a planet with near-Earth conditions, becoming home to many.<ref name="enc42"/>

During the [[Interplanetary War]], Mars became the first colony to rebel from Earth's control. During the events that led up to the war, Mars was home to numerous activists and anti-Earth insurgents. When the first shots of the war were fired, many Martians aligned themselves with the neo-[[Communism|communist]] [[Koslovics]].<ref name="universe"/>

Mars was the site of a decisive battle during the events surrounding the formation of the [[United Nations Space Command]]. The Koslovics attempted to seize control of the shipbuilding plants in the Argyre Planitia, but were repelled by a series of blitzkrieg attacks by the newly-organized [[UNSC Marine Corps|UNSC Marines]] in a series of brutal battles in [[2163]]. This victory marked a significant boost in the morale of the [[United Nations]] forces, and the nascent UNSC subsequently moved on to destroy the Koslovic and [[Frieden]] movements throughout the Solar System.<ref name="enc42"/> After the war ended in [[2170]] with the signing of the [[Callisto Treaty]], remaining rebels on Mars were put down in a series of harsh crackdowns on the planet.<ref name="universe"/>

During the Covenant's [[Battle of Earth|assault]] in the Sol system in late [[2552]], Mars was attacked by the Covenant following the arrival of the [[Prophet of Truth|High Prophet of Truth]]'s [[Truth's fleet|fleet]].<ref name="universe"/> Mars was the site of a large-scale engagement called the [[Battle of Mare Erythraeum]], set on the fields of [[Mare Erythraeum]]. There, [[James Ackerson|Colonel James Ackerson]] and his [[UNSC Army]] forces combated against the [[Fleet of Furious Redemption]]'s ground forces, commanded by [[Lepidus|Jiralhanae Chieftain Lepidus]]. The UNSC lost the battle and Ackerson was taken prisoner.{{Ref/Comic|[[Halo: Uprising]]|Issue=[[Halo: Uprising Issue 1|#1]]}} While the UNSC resistance was crushed, the human population centers on Mars survived the Covenant assault relatively intact.{{Ref/Site|D=01|M=6|Y=2020|URL=https://www.halowaypoint.com/en-us/universe/species/humans|Site=Halo Waypoint|Page=Humans}} The Martian defense on the planet is credited for delaying Covenant forces from pressing their invasion on Earth.<ref name="universe"/>

On [[2552#November|November 18, 2552]], at 15:45 pm, ''High Charity'' arrived near Mars and made a [[Slipstream space|Slipspace jump]] to [[Installation 00]]. This event was recorded by the local Juridical terminal.<ref name="catalog"/>

After the Human-Covenant War, an ONI surgical and research facility and a [[Spartan|UNSC Spartan]] base were established on Mars, which [[SPARTAN-IV Augmentation Program|augmented]] and housed the [[SPARTAN-IV program|SPARTAN-IV supersoldiers]].{{Ref/Novel|Halo: New Blood|Chapter=14}}{{Ref/Novel|Halo: New Blood|Chapter=18}} As the UNSC continued to rebuild in the years following the war, the orbital shipyards located on and around Mars remained its primary shipyards.<ref name="havesmoa"/>

At some point after [[2556]], [[Black-Box]] manipulated UNSC accounting to show that a cabin was built on Mars. In reality, it was built on [[Rossbach's World]].<ref name="rossbach"/>
