8 Printable Martian Habitat Designs That We Want To Live In

Day One: Arrive in lander. Day Two: Print out a habitat.

Design for a 3D-printed Martian shelter

Team: Gamma

If The Martian has taught us anything, it's that surviving on Mars won't be easy. It's really cold, there's practically no oxygen in the atmosphere, no food, no water, and it pummels you with radiation. NASA plans to send the first humans to the Red Planet in the 2030s, and if they want to come back alive, they're gonna need a good, self-sustaining shelter.

Perhaps that’s why the space agency has teamed up with the additive manufacturing institute America Makes to host a competition to design a space habitat. Real architects and engineers were among the contestants. Now the judges have chosen 30 designs to move on to the next stage, and the selection includes some pretty rad concepts.

The goal of the 3D-Printed Habitat Challenge is to design a habitat that could be built with 3D printers using local materials or a mission's waste products. "The vision," says the website, "is that autonomous habitat manufacturing machines will someday be deployed to the Moon or Mars to construct shelters for human habitation." Although 3D printing is hardly ready to go to space, it's never too early to start planning ahead.

Contestants were challenged to design a living space for a hypothetical set of four astronauts. The 1000-square-foot habitat would need to contain life support systems, bathrooms, cooking areas, and sleeping quarters.

The designs are pretty detailed, including the “locations of electrical outlets, fluid supplies and drains, and ventilation registers should be included.” Contestants also had to set aside at least three areas for life support systems, measuring 45 cubic feet apiece, to provide clean air and water and regulate pressure and temperature.

The top 30 designs have been selected, and may be whittled down before the final judging at New York City's Maker Faire at the end of September. The first, second, and third place winners will take home $25,000, $15,000, and $10,000, respectively.

Here are some of our favorites.

The Martian Vault

On Earth, "cloister vault" domes have stood the test of time, forming architectural marvels that stand upright for thousands of years. Tomasz Dzieduszynski is hoping they'll prove equally durable in the harsh Martian landscape. His habitat concept uses an inflatable scaffolding to guide 3D-printing robots, which would deposit a cement made from Martian soil. The habitat's layer of honeycomb-shaped insulation is intended to protect against radiation and small meteorites.Designed by Tomasz Dzieduszynski

Staye A While

This spiraling underground structure would live beneath a frozen sea near Mars' equator. Excavation of the ice could potentially free up drinking water, and placing the structure underground helps to shield Martian explorers from radiation.Designed by Team Staye

LavaHive

This team decided to take advantage of inflatable space habitats--perhaps like the ones Bigelow Aerospace is developing. Like tents, these structures could be deflated during the long journey to Mars, to save room in the spacecraft, then pop open once they reach their destination. But Team LavaHive takes it a step further by connecting the inflatable shelters via tunnels and mini habitats built from sand.Designed by Team LavaHive

Marsapia

Martian sand contains two valuable resources: iron and silica. This team proposes to isolate these elements from the soil and use them to create a bulbous structure comprise of an iron latticework paned in a granite-like silica. "The resulting steel and silica forms will serve as bunkers," they write, "protecting the Martian inhabitants against solar radiation, small bolide impact, strong prevailing winds, and related sand storms."Team: Mars Terrain Intelligence Collaborative

Labyrinth

Rustem Baishev is preparing for the day when Mars becomes a heavily populated tourist destination. His labyrinth-like design can expand indefinitely, built by a "nuclear powered crawling extruder" which mixes the Martian soil with a bonding agent and shapes it.Team: Rustem Baishev

Mollusca L5

It may look like a booger, but this is a pretty cool design. Inflatable living modules are encased in a locally sourced 3D-printed glass dome, giving astronauts a sort of "front yard" on Mars.Team: LeeLabs

Donut House Mk. I

The appropriately named Donut House would be made out of a basalt clay reinforced with fibers. The ring-shaped design allows for partitioning the habitat into different segments, so that if one section gets damaged by, for example, a meteorite, the other sections can still provide shelter to astronauts.Team: A.R.C.H.

Ice House

Instead of using soil as a building material, this team decided to "follow the water". After mining the ice at Mars' northern pole, they propose to use a unique 3D-printing process that "harnesses the physics of water" to construct a radiation-proof shelter. "Ice House is born from the imperative to bring light and a connection to the outdoors into the vocabulary of Martian architecture," they write.Team: SEArch/Clouds Architecture Office
