The International Space Station is growing mould —  inside and outside

The International Space Station is growing mould —  inside and outside | CBC News.

The spores — which astronauts spend hours cleaning every week — can survive X-ray exposure at 200 times the dosage that would kill a human being, according to Marta Cortesao, a microbiologist at the German Aerospace Centre in Cologne, who is presenting the research.

And that’s not all. The common mould spores found on the ISS — aspergillus and penicillium — can also survive extreme temperatures, ultraviolet light, chemicals and dry conditions. Their resilience not only makes it harder to clean, but more likely to survive long-term.
