ISS Microbes Extract Platinum and Palladium From Meteorites

Astronauts aboard the International Space Station used bacteria and the fungus Penicillium simplicissimum to bioleach platinum and palladium from L-chondrite meteorite samples. The experiments showed microgravity enhances the fungus’s metal uptake and release, making space-based bioleaching more effective than on Earth and highlighting a potential path toward mining valuable metals in space, alongside ongoing asteroid-mining efforts like TransAstra.

ISS Microbes Point Toward Sustainable Asteroid Mining

An ISS BioAsteroid experiment tested bacteria and a fungus on asteroid material under microgravity and Earth gravity. Microbes extracted several metals, including palladium and platinum, sometimes outperforming non-biological leaching, though results varied by metal and organism. Overall, 44 elements were extracted, 18 biologically, suggesting microbes could enable more sustainable space mining, but much optimization remains.
