Long-duration spaceflight can chip away at an astronaut's health, prompting scientists to find new ways to make living in space easier on the body. The journey to outer space is incredibly dangerous, but crews must also face day-to-day hazards, such as exposure to cancer-causing radiation, microgravity and extreme isolation.

The findings are published in Nature Communicatio
