Argyre Planitia



Argyre Planitia is a plain located in the Argyre Impact Basin in the southern highlands of Mars. Its name comes from a map produced by Giovanni Schiaparelli in 1877; it refers to Argyre, a mythical island of silver in Greek mythology.

Following the colonization of Mars, the region became a noted center of spacecraft construction. As conflict in the Solar System intensified in the 2160's, the shipbuilding plants fell under control of the Koslovics. In 2163, the United Nations organized a successful major offensive against the Koslovics in the Argyre Planitia. This marked the historical first deployment of Marines outside of Earth, and thus, the first official conflict of the UNSC.
