Climate change. Antibiotic-resistant superbugs. Paul Ryan dabbing. We may be looking to leave this planet sooner rather than later. Since Mars is the most plausible destination, NASA held a competition for design teams to come up with potential homes on the Red Planet. The 3D-Printed Habitat Challenge, which was part of a the larger Centennial Challenges Program, received some rather unique entries, with the winner being the Mars Ice House, a design from Team Space Exploration Architecture and Clouds Architecture Office in New York. The inflatable dome lined with ice is designed to protect humans from cosmic and solar radiation while allowing them to move around inside without a spacesuit. Check out some shots of the finalists above.
