Comfort and Heat Control During Extended Space Flights 961538

The inability to adequately assess overall temperature in contradictory thermal conditions is problematic for monitoring the safety and comfort of the astronaut during extended EVA. A nonuniform heating/cooling system applied to the surface of the body provides a paradigm for identifying the most sensitive areas for measuring overall heat status. Manipulating warming /cooling tube patterns in the space suit during EVA has potential in providing a normal heat topography. Systematically varying astronaut's heat exchange onboard can enhance comfort and performance and prevent health problems that accompany living in a closely-controlled, constant environmental habitat.
