The purpose of this project is to research the viability and sustainability of fungal mycelium as a construction material for lunar and Martian habitation. To investigate this, we curated information from numerous peer-reviewed journals and industry sources. Mycelium has shown promise as a building material and some species of fungi are able to survive, or even thrive, in Martian and Lunar conditions. Three different fungi species been shown to survive in similar environments: Schizophyllum commune survived 200 Gy irradiation for 3 days and had improved growth in microgravity (Wösten et al., 2018); Cryomyces antarcticus survived 1000 Gy irradiation with no damage (Pacelli et al., 2017); Cryomyces minteri showed similar results, but with significant mutations (Onofri et al., 2018). Secondly, Ganoderma lucidum and Pleurotus ostreatus are effective at producing a wide array of building materials (Haneef et al., 2017). Mycelium biofoams have also been shown to be a great insulator, which is crucial with the average temperature on Mars being -62 degrees Celsius (Yang et al., 2017). While research to date suggests that mycelium offers promise as an alternative material, some questions remain. In particular, mycelia materials have not been compared to other biocompound options, both in terms of strength and economic viability. Based on our literature review, mycelium appears valuable to research further with the goal of determining whether growing fungi in Martian or lunar landscapes could provide services to support human space exploration.
