MARSHA is a first principles rethinking of what a Martian habitat could be – not another low-lying dome or confined, half-buried structure but a bright, multi-level, corridor-free home that stands upright on the surface of Mars. Where structures on Earth are designed primarily for gravity and wind, Martian conditions require a structure optimized to handle internal atmospheric pressure and thermal stresses. Marsha's unique vertically oriented, egg-like shape maintains a small footprint, minimizing mechanical stresses at the base and top which increase with diameter. Standing tall on the surface grants the human crew a superior vantage point to observe a dynamic landscape with weather patterns, clouds, and shifting hues – their new home and object of study both. The tall, narrow structure reduces the need for a construction machine to continuously rove on the surface, reducing risk and increasing speed and accuracy.
These innovations challenge the conventional image of “space age” domes by focusing on the creation of spaces tuned to both known and anticipated physical and psychological demands of a Mars mission.
