International Space Station is too clean, scientists say

Is the ISS Too Clean for Astronauts’ Health? New Study Finds the Space Station Lacks Microbial Diversity
Turns out, being too clean can be a bad thing. Scientists suggest the International Space Station (ISS) is so sterile that it may be making astronauts less healthy—and could even lead to problems like skin rashes,
The International Space Station Might Be “Too Clean” for Astronauts’ Own Good
“Future built environments, including space stations, could benefit from intentionally fostering diverse microbial communities that better mimic the natural microbial exposures experienced on Earth, rather than relying on highly sanitized spaces,” says co-first author Rodolfo Salido at UC San Diego.
Should the International Space Station be dirtier?
The ISS’s microbial environment most closely resembles a hospital isolation room. It could be making astronauts sick.
The International Space Station May Need More Microbes to Keep Astronauts Healthy
The overly sterile environment of the International Space Station is missing important microbes, a new detailed map shows. If we want to live off Earth, we may need to take more of our bacterial frien
The ISS Might Be Too Clean For Astronauts’ Health
Some of the health effects astronauts suffer on the International Space Station (ISS) may not be a consequence of weightlessness, as previously thought, but of the ISS being too clean, a new study proposes.
