Mushroom Houses on Moon

**Mushroom Houses on the Moon: NASA’s Vision of Mycotecture for Space Habitats** NASA is advancing its research on an innovative and groundbreaking concept to create habitats on the Moon and Mars using fungi. The space agency’s Mycotecture Off Planet project, backed by a $2 million funding initiative, aims to develop technologies that could potentially allow for the growth of sustainable, self-healing homes for future space explorers. This approach, based on mycelium—the root-like structures of fungi—could revolutionise space habitation and open new avenues for human colonisation beyond Earth. ### The Promise of Mycelia-Based Moon Habitats The concept of mycelia-based Moon habitats revolves around using fungal networks to construct sustainable, bio-based living structures. These habitats would be grown from dormant fungi transported from Earth, which would be activated upon arrival by simply adding water. This process, once initiated, would allow the fungi to grow into strong, stable structures suitable for living. The proposed design of these mycelial habitats features a three-layered dome structure. The outermost layer would be made of ice, serving as a shield against radiation. The middle layer would contain cyanobacteria, a type of bacteria capable of producing oxygen through photosynthesis. Finally, the innermost layer would be composed of mycelia, which would grow to form the primary living space for astronauts. This innovative multi-layered approach offers several distinct advantages: 1. **Lightweight transport of materials**: Mycelium spores are lightweight and compact, making them easier to transport compared to traditional building materials. The minimal weight also means reduced launch costs. 2. **Utilisation of lunar resources**: Mycelium can be grown using lunar resources, reducing the need to rely on Earth for all construction materials. 3. **Self-healing structures**: The fungi can naturally repair small cracks and damage, providing long-term durability. 4. **Radiation shielding and insulation**: The layers of mycelium and ice would provide excellent insulation from the extreme temperatures and harsh radiation found on the Moon. 5. **Biodegradability**: Mycelium is biodegradable, allowing for habitats that have minimal environmental impact, a crucial factor for space colonisation. NASA’s Ames Research Center is leading this research, with a focus on demonstrating the feasibility of fungal-based habitats in space conditions. If successful, this could lay the foundation for constructing future homes on the Moon and Mars using nothing but local materials and a bit of water to kickstart the process. ### The Role of Mycotecture in Space Colonisation The use of fungal structures for building habitats is gaining attention for several reasons. Mycelium, the vegetative part of a fungus, has remarkable properties that make it an ideal candidate for constructing space habitats. The concept of *Mycotecture*—the use of fungal materials in architecture—could become a key component of space colonisation efforts. Fungal structures, particularly those made from mycelium, offer several benefits for space colonisation: 1. **Lightweight and compact spores**: Mycelium spores are highly portable and can be transported to the Moon or Mars with relative ease. Upon arrival, they can be grown on-site using local materials, which significantly reduces the need to carry heavy construction materials on space missions. 2. **Radiation shielding**: Mycelium-based materials are known to provide radiation shielding, a crucial feature for space habitats. The Moon and Mars have little atmosphere to protect against harmful cosmic rays and solar radiation, but fungal bio composites can offer a natural barrier. 3. **Thermal insulation and structural stability**: Mycelium is an excellent insulator, helping to maintain stable temperatures inside the habitat. Its structural stability, once grown into a cohesive form, can offer a robust shelter for astronauts. 4. **Sustainability**: Fungal materials are biodegradable and renewable, making them an environmentally friendly option for long-term space habitation. After their useful life, the structures can naturally decompose without harming the lunar or Martian environment. Some species of fungi, such as melanised black fungi, have shown remarkable resilience in space-like conditions. These fungi, which contain the pigment melanin, have demonstrated the ability to thrive in high-radiation environments. This makes them a particularly promising candidate for use in the construction of habitats on the Moon and Mars. NASA and other space agencies are actively exploring and developing fungal-based building techniques, with the goal of testing prototype structures in space as early as 2028. ### Radiation-Deflecting Mycotecture One of the most critical challenges for human space exploration is radiation exposure. Long-duration missions to the Moon and Mars would expose astronauts to dangerous levels of cosmic radiation. This makes the development of effective radiation shielding essential for the survival of space explorers. Mycotecture, the use of fungal materials in construction, holds significant promise in addressing this issue. Melanin, a pigment found in fungi, has been shown to offer natural protection against ionising radiation. NASA researchers are investigating the potential of using melanised fungi to create structures that can shield astronauts from harmful cosmic rays. Key advantages of Mycotecture for radiation protection include: 1. **Natural radiation resistance**: Melanosed fungi have been observed thriving in environments with high radiation levels, such as Chernobyl, where fungi have adapted to grow despite the extreme radiation. 2. **Multi-functional material**: Fungal composites can serve dual purposes, providing both structural support and radiation shielding. This reduces the need for additional materials to perform both functions. 3. **Resource efficiency**: Mycelium can be grown using local materials, significantly reducing the need to transport heavy radiation shielding from Earth. 4. **Adaptability**: Fungal structures can be engineered to grow into specific shapes, allowing for customised designs that offer targeted radiation protection. While Mycotecture remains in the experimental stage, its potential for addressing the critical challenge of radiation exposure is a promising development in space exploration. If successful, this approach could dramatically improve the safety of astronauts on long-duration missions to the Moon, Mars, and beyond.

### A Vision for the Future of Space Habitation NASA’s work on mycelium-based Moon habitats is part of a broader vision for sustainable space exploration. As humans push further into the cosmos, the ability to build habitats using local resources will become increasingly important. The Mycotecture approach, which uses fungi to grow homes, offers an exciting solution that aligns with the principles of sustainability, efficiency, and adaptability. Mycelium-based habitats are not just a theoretical concept; they are part of a growing field of research that aims to revolutionise the way we live in space. By harnessing the power of fungi, NASA and other space agencies are taking steps towards creating living structures that can grow, heal, and protect future astronauts from the harsh conditions of space. As we look towards the future, the prospect of mushroom houses on the Moon is not as far-fetched as it might seem. With continued research and development, Mycotecture could play a crucial role in enabling humanity’s expansion into the final frontier, allowing us to live and thrive on other worlds.
