Story summary
  • The BioAsteroid project aboard the International Space Station tested Sphingomonas desiccabilis and Penicillium simplicissimum on L-chondrite material to assess microbial extraction in microgravity.
  • The microbes extracted 18 of 44 elements, including palladium and platinum, under microgravity.
  • Biological extraction remained effective in space, while non-biological methods were less so.
  • The findings indicate microbes could play a key role in future space mining, pending optimization.
