Because of the water content below the surface and at the poles, as well as the relative ease of creating oxygen from elements present, Mars is humanity’s oldest and longest running terraforming project.

First reached by Terran humans in the late World War Era and colonized shortly thereafter, Mars became a founding member of the Compact.
