In the beginning, you will be dependent on supplies from Earth and will have to travel often between the Mars Space Station and the planet's surface. As the colony expands over time, you will shift your activities to construct mines, power generators, water extractors, greenhouses, oxygen factories, and shelters. Your goal is to develop a self-sustaining colony independent of any terrestrial organization. This will require understanding the importance of water, air, power, and food — the necessities for survival. Do you dare take part in humankind’s biggest challenge?
