These are NASA’s top three picks for homes designed for life on Mars and, perhaps, beyond. The shelters were designed by the finalists in the space agency’s 3D-Printed Habitat Challenge, which began in 2015. In the next round, the finalists will 3D-print models of their designs. There is $800,000 in prize money.
