Mars Base

A robust design, with triple-redundancy and near-complete submersion of primary habitation units and the control center. Each habitation/research section has a void in the middle for Water Storage, which, via wind and solar power, would be electrolyzed into Oxygen and Hydrogen - for breathing, and as fuel respectively. The cartwheel objects extending from the top of the habitation/research units are greenhouses for food production and to aid atmospheric scrubbers in maintaining acceptable carbon dioxide levels. There are three air docks extending from the central control center, and three ways for vehicles to enter and leave. The central control center would also have redundant hydrogen storage tanks piped from the habitation/research unit's electrolysis apparatus. The mast-like object extending from the control center represents communications systems.
Initial construction of the facility could be accomplished with robotic excavation and assembly. Furthermore the feasibility of this scale of a project could be enhanced by the construction of a linear accelerator device to more cost-effectively send materials and resources to Mars.
To estimate facility scale - the greenhouses are ~3 meters in height.
