NASA picks the top three designs for housing on Mars, if humans would ever call the red planet home.
The space agency picked three finalists in its “3D printed habitat challenge.”
The chosen homes include small holes for natural light, and one even contains a room for growing plants.
NASA tasked teams with designing shelters suitable “to boldly go where no man has gone before.” The mission plans include Mars, the moon and possibly beyond.
The three teams split a prize of $100,000 between them. They will now have to create 3D print scale models of their homes for the next round. $800,000 in prize money is up for grabs.
