Water is the basis for life. Our solar system is proving to be increasingly saturated with water. More than five million cubic kilometers of water ice have been identified on Mars, enough to cover the planet to a depth of thirty five meters. The Mars Ice House project taps into this vast supply of water ice to propose an autonomously 3d printed habitat for four explorers. The project has been awarded first place in NASA's Centennial Challenge Mars Habitat Competition, and is slated for a full scale prototype in the next phase.

Formally, the project is deliberate in redefining the prevailing diagram for off-planet habitats. The prevailing precedent has been inflated domes covered by a layer of regolith, which yields dark and claustrophobic habitats with potentially disastrous consequences for crew motivation and mental health. Mars Ice House redefines this typology by innovating a translucent fin shaped double shell structure contained within a transparent ETFE film. The form is driven by a humanist approach with crew comfort and well-being as key design factors.

The 'yard' is an unprogrammed space between the inner habitat and outer shell. This area is not for any specific function (ie. sleeping, eating, working) but an undefined open space for contemplation, relaxation, exercise, game play or anything the crew decides to do. While not fully conditioned, this space is pressurized and can be inhabited with a simple oxygen mask. It also serves as a buffer space, absorbing leaks from the habitat environmental control and life support systems to minimize forward contamination of the Martian wilderness.

Why ice? Water ice is an effective radiation shield, diminishing both ultra-violet solar and galactic gamma rays to safe levels with only a 5cm thick shell. Ice is translucent allowing natural daylight to stream into the dwelling connecting inhabitants to circadian cycles necessary for maintaining healthy bio-rhythms. The translucency gradient of the ice shells can be modulated to achieve transparent windows allowing for views of the Martian landscape beyond, which has been proven to improve crew morale and psychological well being. Water ice is abundant in the northern latitudes and easily extracted as it's covered by only 30cm of loose regolith.

It takes less energy to process and print with water, since the natural climatic and atmospheric conditions (below freezing with low humidity) allow us to take advantage of the physics of phase transition.
