Researchers from NASA are developing a number of projects that can help future explorers of new planets in the arrangement of new habitats. Total with you from Earth you will not take awayincluding materials and construction equipment. Cultivation technologies may be a way out. mushroom buildings. An excellent and low-cost alternative for early alien settlements.

Despite the apparent absurdity of the solution, the proposed method for growing self-healing buildings is not as complex as it might seem at the first moment. To create walls and objects from mushrooms, scientists in experiments use mushroom myceliumand not the fruiting body — the leg, the hat, and so on. A year ago, by the way, researchers from Stanford and Brown Universities grown a stool as part of the mycoarchitecture research project Ames center NASA (Ames Research Center). And from the stool to the wall there are not many steps.
The concept of the Martian abode of mushrooms is a three-layer structure. The outer layer is water ice, it is transparent for the photosynthesis of bacteria on the lower layers and supplies them with water. The second (inner) layer consists of cyanobacteria, which produce oxygen and nutrients. The third layer is actually the mycelium of fungi that grow in a given frame in the desired configuration. After growth is complete, when the mycelium fills the entire framework, the inner layer is burned to stop growth and disinfection. The house is ready – move in and inhabit.
NASA is confident that the technology will be safe and will be under full control, which will not allow to infect the Martian environment with terrestrial bacteria and fungal material. The agency does not exclude that similar technology can also be used in terrestrial conditions. In principle, spores arise mainly after the appearance of fruiting bodies, so the main concern will be to isolate the mycelium from entering the border biosystems.
