The next frontier of human endeavor! The first settlers arrived on Mars in the year 2037. In the decades after the Mars Base Camp was established, private exploration companies started working towards the creation of a self-sustaining colony. As a chief astronaut from one of these enterprises, you want to be a pioneer in developing the biggest, most advanced colony on Mars. In the beginning, you are very dependent on supplies from Earth, and have to travel a lot between the Mars Space Station and the surface of the planet. As the colony expands, your reliance on material from Earth will lessen as you construct mines, power generators, water extractors, greenhouses, oxygen factories, and shelters. Your aim is to become a self-sufficient colony, independent of any terrestrial organization. This will require carefully balancing the importance of water, air, power, and food - the things we need to survive.
