We just need a basic layout for the base.

I was thinking that we would start with an airlock, a 4-way junction connected to it, and a power management module to the right and the life support module to the left.  The outside air processor and tanks would connect to the life support module.  The solar panels would connect to the power module.  The 4 way junction also connects to another junction, and it to a water management module, which connects to an outside ice melter and water tank.  I'll try to draw it out, but I'll have to do it in ascii, as I can't post pictures.

atmo[]  []Water
        []  []
[===][][][]
AL  []
       []Power

After that, we can connect living areas and a 'ponics bay at the least.
