The Stanford torus was a design concept for a permanent space habitat for 10,000 residents proposed at Stanford University during the summer of 1975. Though not the only idea for a ring-shaped space station that would provide gravity to inhabitants, it’s one of the designs that received significant research from NASA. MSP! has created a microscale LEGO version, complete with buildings and landscaping on the ring’s interior. Mounted on an unobtrusive stand, this would look fantastic on any astronaut’s desk.
