A person???s ability to work is reduced if the body is unable to properly regulate its temperature. Ground-based models suggest that living in the zero-gravity environment of space impairs the body???s ability to regulate temperature. This is a serious concern, especially during periods of physically demanding work such as a spacewalk.
Dr. Craig G. Crandall and colleagues seek to determine if living in zero gravity actually impairs the body???s ability to regulate temperature. They will evaluate temperature regulation during steady-state exercise before, during and after a mission onboard the International Space Station.
The project???s data will lead to improved astronaut safety during missions and possibly increased physical work capacity during events such as spacewalks.
