| Overview |
| The test subjects for the Sleep-2 experiment are John Glenn and Chiaki Mukai. Test Operators are Scott Parazynski and Steve Robinson. The Sleep-2 experiment will evaluate the normal sleep patterns of crew members before, during, and after space flight in order to identify the factors that may be contributing to sleep disturbances that are known to occur during space flight. This experiment will also perform a preliminary evaluation of the effectiveness of the pineal hormone melatonin as a hypnotic during space flight. Crew activities include donning the sleep gear and manual testing of alertness during several flight days, providing and processing urine samples, and monitoring body core temperature rhythm throughout the flight. |
