Look at these beauties. I have no idea how realistic these designs could be, but dang, these are the coolest Mars habitat designs I’ve ever seen. The video is compelling, too:
I would watch the hell out of a scifi movie set in those habitats. Seriously, do people option architecture for movies? I would option that for a movie.
They’re designed by a firm called AI / Spacefactory, and there are more renderings and process images on their site.
