As humans plan expeditions to places such as the Moon and Mars, biomining could offer a way to obtain needed materials on other planetary bodies rather than bringing them from Earth. However, microbes and rocks interact differently outside of Earth’s gravity, potentially affecting output from extraterrestrial biomining. A new investigation on the International Space Station is studying how microbes grow on and alter planetary rocks in microgravity and simulated Martian gravity.
