"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

China's Tiangong space station is expected to welcome its first foreign visitor — a Pakistani astronaut who will likely become the first from the Islamic republic to fly to outer space, according to a heavyweight cooperation agreement.

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.

Learn how the excessive cleanliness of the International Space Station poses health problems for astronauts and why scientists are looking to microbes for solutions.

The International Space Station is too clean, and making it “dirtier” could improve astronauts’ health, claims new research. They often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space.
