Instead of Building Structures on Mars, we Could Grow Them With the Help of Bacteria universetoday storybywill
program launched in 2010. For missions to Mars, this would include using local regolith to create building materials and water ice for astronaut consumption, irrigation, and to create propellant and oxygen gas.
“This will be very important if there is no human labor, especially on Mars. They can do this automatically. We propose that instead of shipping materials from Earth to Mars, we can directly use in-situ materials. Fro sample, the soil, the atmosphere, and the water on Mars, then we can just bring some bacteria or fungal spores and they will build the bricks for us.”
In this proposed autonomous system, the cyanobacteria and filamentous fungi perform different capturing carbon dioxide and converting it to carbonate ions and 2) providing oxygen and organic compounds to support the filamentous fungi.

While biomineralization is something researchers have been investigating for years, this proposal represents a first for two reasons. For starters, it is the first project to consider filamentous fungi as a biomineral producer instead of bacteria. Dr. Jin has conducted extensive research on biomineralization in recent years, and her results have demonstrated that filamentous fungi possess distinctive advantages over bacteria.
