The Ice House is an innovative and futuristic architectural conception, created by Team Space Exploration Architecture and Clouds Architecture Office, that is the winner of NASA's 3-D Printed Habitat Challenge Design Competition. The point of this contest was to seek out architectural concepts for exactly how the wonders of 3D printing could be utilized to put together shelters on Mars.
What's great about the Ice House is that it would be built using something that is believed to be quite abundant on Mars -- water. For this reason, the shelter is designed to be situated at Alba Mons in the northern hemisphere of Mars, as it is believed that sub-surface water ice is plentiful here. This water would be used to help create ice for a building material but would also of course be crucial towards sustaining life.
As humans look to explore the interstellar world in newer, bolder ways, concepts like the Ice House will be crucial to helping coming up with ways to sustain life on other planets.
