Earth analog priors for deployable Mars habitats Human expansion into off-Earth environments is transitioning from short-duration missions toward sustained presence, where habitats must remain safe and operable under persistent environmental forcing1,2,3. On Mars, extreme cold, low atmospheric pressure, dust abrasion, radiation exposure, and large diurnal thermal swings impose chronic degradation pathways on envelopes, interfaces, and mechanical systems4,5,6. In such settings, the limiting constraint is often not initial construction feasibility but the long-term burden of maintenance, refurbishment, and replacement under restricted logistics7,8. A central scientific and engineering question therefore emerges: which habitat morphologies minimize maintenance-driven material demand and resupply burden while remaining compatible with heterogeneous construction routes and mission architectures? Habitat morphology is not a purely aestheticim variable in planetary contexts9,10. Geometry governs envelope exposure relative to usable volume, thermal exchange area, wind-driven and particle-driven loading surfaces, and the scaling of joints and seams that frequently dominate failure and repair events11,12,13. Even under simplified assumptions, surface-area-to-volume efficiency, plan compactness, and height–perimeter scaling affect both operational energy demand and the rate at which envelope and structural components require repair or replacement14,15,16. These geometric influences become more pronounced under extreme forcing because marginal increases in exposure can trigger non-linear increases in degradation, such as accelerated corrosion or abrasion in high-salt... https://www.nature.com/articles/s44453-026-00034-z
