'''Argyre Planitia''' is a plain and city located in the [[wikipedia:Argyre Planitia|Argyre Impact Basin]] in the southern highlands of the [[human]] [[Human colonies|colony]] of [[Mars]].<ref name="enc42">''[[Halo Encyclopedia: The Definitive Guide to the Halo Universe]]'', page 42 (2011)</ref><ref name="mythos50">''[[Halo Mythos]]'', pages 50-51</ref> Its name comes from a map produced by [[wikipedia:Giovanni Schiaparelli|Giovanni Schiaparelli]] in 1877; it refers to Argyre, a mythical island of silver in Greek mythology. 

==History==
Following the [[Human colonies#Interplanetary age|colonization]] of Mars, Argyre Planitia was settled as a city home to shipbuilding plants.{{Ref/Reuse|enc42}}{{Ref/Reuse|mythos50}} As conflict in the [[Sol system]] intensified in the 2160s, the shipbuilding plants fell under control of the [[Koslovics]], becoming the hub of Koslovic activity on Mars. In [[2163|December 2163]], the [[United Nations]] organized a [[Mars Campaign|successful major offensive]] against the Koslovics in the Argyre Planitia. This marked the historical first deployment of [[UNSC Marine Corps|Marines]] outside of [[Earth]], and thus, the first official conflict of the [[United Nations Space Command]].{{Ref/Reuse|enc42}} [[Frieden]] forces also attacked the city at the same time; within hours of the initial battle, Argyre Planitia's infrastructure was almost entirely destroyed. Within the following weeks, battles continued to occur throughout Argyre Planitia as Koslovic forces were pushed to the city's outskirts.{{Ref/Reuse|mythos50}}

On [[2552#October|October 13, 2552]], gravitic and radiation anomalies were detected near Argyre Planitia. In response, the UNSC's [[Naval Special Warfare Command]] deployed a scouting team led by [[Staff Sergeant]] [[Malcolm Geffen]] to investigate and conduct an on-site search and assessment. The scouting team discovered [[Active camouflage|cloaked]] remote sensor platforms of unknown origin, triggering cryptonym WIDEAWAKE. After consultation with [[Admiral]] [[Margaret Parangosky]], [[Commander-in-Chief of the Office of Naval Intelligence|Commander-in-Chief]] of the [[Office of Naval Intelligence]], [[Fleet Admiral]] [[Joseph Harper]] issued a priority-1 stand-down. Remaining records were redacted,<ref name="lootcrate2">''[[Halo Legendary Crate]]'', [[Halo Legendary Crate/Data Drops|Data Drop #2]]</ref> though the sensor platforms were likely deployed by the [[Covenant]] in preparation for the [[Battle of Earth]].
