What is the obsession with surface habitation?
Underground tunnel habitation seems to me to have the advantage:
>protects from the day-night thermal cycles
>Small digging equipment is easier to get there than entire habitats
>More easily expandable than a surface module-based approach, if you need more room, dig your tunnels deeper
>Easier to make airtight/safe, an inflatable tube could be blown up until it fills the tube, then you'd only have to worry about punctures at either end of the tube and not against the wall and these would be easily patched. A hole in a hard shell for a surface module would be more devastating and hard to repair
If dug into the side of a cliff/ravine at it's base access to the habitat would be even easier than in pic related
