The Mars Colony Corporation (MCC) was founded in 1974-1975. It was set up by multinational interests along with their parcels of businessmen, mining companies, scientists, engineers, military advisors, and intelligence officers. It is composed of five settlements, the capital of which is Aries Prime. This settlement was comprised of the same types of people and organized in the same way as the original colonies were settled in America. People with all types of skills, ranging from scientists to farm workers, live in this colony. The Mars Defense Force (MDF) is contracted to defend the MCC settlements.
