It was probably present in the past and has been proven to occur below the surface, but it is scarce. Concrete that requires relatively large quantities of water, for example, would probably be an inappropriate construction material. Atmosphere mostly carbon dioxide. Inhabitants will need to wear spacesuits when outside. Trees, however, could grow except for the scarcity of surface water.
Trees use carbon dioxide and emit oxygen.
No protective ozone layer. Since inhabitants will need to wear spacesuits, dexterity will be limited, and outdoor construction and assembly activities will need to be minimized. Oxygen will need to be conserved, and habitat exit-entry airlocks will be required. Atmospheric pressure is low, about the same as being 100,000 feet above sea level on Earth. Interior of the planet is rocky.
