"We hope the impact of this research will be to guide future studies that keep astronauts healthy during extended space travel and in colonizing space."

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 human body was not built for spaceflight, with its microgravity conditions, exposure to high-energy radiation and other issues. As a result, trekking beyond the Earth's confines causes many physiological changes that affect an astronaut's health.

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,

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.

Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. A new study published in the journal Cell suggests that these issues could be due to the excessively sterile nature of spacecraft.
