Study of the Impact of Long-Term Space Travel on the Astronauts' Microbiome
The Microbiome experiment investigates the impact of space travel on both the human immune system and an individual’s microbiome (the collection of microbes that live in and on the human body at any given time).
To monitor the status of the crewmembers' microbiome and immune system and their interaction with the unique environment of the International Space Station (ISS), we will take periodic samples from different parts of the body and the surrounding ISS environment. As part of this study, the likelihood and consequences of alterations in the microbiome due to extreme environments, and the related human health risk, will be assessed.
