Mars was the fourth planet from the Sun in the Solar System. It was terraformed in the 21st century and became the most populated planet. Mars was sometimes nicknamed as the "Red Planet" because of its reddish appearance, due to iron oxide prevalent on its surface. According to Spike, Mars was a good planet to live on if you're rich.
Life on Mars Edit
Mars colonies were mostly built inside large craters on the surface, covered by artificial atmosphere that was constantly replenished via large devices at the edge. In this way, a colony could be established with atmospheric and climatic features similar to those of Earth. Large cables connected different crater-cities and covered highways allowed travel between.
Major locations Edit
There were several sessions portraying Mars that didn't give the name of the city. The Martian city portrayed in Stray Dog Strut seems to have a very large Chinese population, for Chinese elements are constantly depicted: the announcement at the Astral Gate is in Mandarin; the various street signs are all written in Chinese (not Japanese Kanji); the bartender that Abdul Hakim interacts with speaks Cantonese; the group of civilians that block the scientists in their pursuit seems to be playing a Chinese chess called Xiangqi; Spike and Jet also joke about having Peking duck throughout the session.
Mars was also portrayed in sessions 5, 18, 20, 21, 22, 23, 25 without specifying the name of the city in which it was set. Since Mars was the most populated planet in the system, these could all be different cities. Only sessions 25 and 26 explicitly set certain scenes in Tharsis, and the movie was almost entirely set in Alba City.
Mars seems to be an extensive trading center, as can be assumed by the store clerk's statement in Session 2, "You can buy anything here on Mars, from guns to human lives."
