For stability f(nat)LV < f(nat)OV
f(nat)OV>>f(nat)LV, t can possibly
Assumptions
Took into account cylindrical hab only
Thin walled cylinder

Works in Progress
D/h vs. total mass study (Resizing of Heatshield?)
Better modeling of vehicle for take off loads
Landing loads/landing structure
Internal housing struts
