NASA is sharing information about its myco-architecture program, in which experimental fungus-based building technologies could be the feasible future of Mars habitats. “Science fiction often imagines our future on Mars and other planets as run by machines, with metallic cities and flying cars rising above dunes of red sand,” NASA says. “But the reality may be even stranger.”

The myco-architecture (myco is the prefix meaning “fungus”) NASA is excited about isn’t only a new way to make furniture, although it can do that, the agency says. Mushroom House—not its real name—is an integrated habitat with layers. The tough, complex fibers made by fungal mycelia are building blocks of furniture, interior walls, and the innermost layer of the outer shell.
