Engineering fungal mycelium to create viable building materials for on Mars is not a small challenge. This project, which was inspired by conversations with Lynn J. Rothschild from NASA, whom we owe thanks both for the inspiration and subsequent sparring on ideas, has relied on a several scientific fields to try to tackle the problems we have found along the way. Our design inspired by the idea of simple and cost-effective construction on Mars, which its simplest terms says that instead of spending millions if not billions on transporting the materials needed for habitats to Mars, one could instead bring a set of vials: One vial with a cyanobacteria, which will harness the carbon in the atmosphere and the oxygen in the martian ice to create biomass that can be used as ‘substrate’ for fungal cultures to create range of biomaterials. Our project focussed on the fungal aspect of such a system and how it could be used to create building materials for habitat construction on-site. This exciting challenge raises many questions that have to be answered and even more problems have to be dealt with. First off, how does one cultivate fungi on Mars? Moreover, Which fungal species should we use? How do we make the system cost-effective? Are the strength of fungal materials determined by any distinct genes and it is possible to regulate these in a way that will make our materials even tougher? We set out to answer these questions, the answers of which guided the creation of our final design
