Robotic Infrastructure for Mars Outpost Water Supply

Howe, Scott A. / Wilcox, Brian H.

Intercontinental rovers servicing automated solar-powered Rodriguez Wells can supply water for Human Exploration on Mars. This paper describes a solar-powered multivehicle concept that can turn water resources obtained from mid-latitude glacier ice into a sustained water supply. A robotic drilling platform is proposed that can access relatively pure water ice in mid-latitude Martian glaciers through 1-10m of loose regolith, whereupon longdistance tanker rovers continually traverse terrain between the drilling operation and human outposts located in Mars equatorial zones. Robotically deployed solar-thermal panels will be able to passively heat warm water that is delivered into a Rodriguez Well (a melted cavity in an expanse of water ice such as a glacier). Newly melted water will be pumped up out of the well and cycled through the solar panels to fill tankers. The tankers will consist of multiple four-wheeled linked cars in a tram-like configuration that can overcome steep terrain and obstacles. The system will be able to deliver its own landed mass of water to the human explorers every ~74 Mars days. The resources, power, vehicle configurations, and detailed functions are described.
