The crew has been participating in two experiments. The first study involves a correlation between performance and exercise. The experimental group exercises 30 minute per day and takes a 12-minute performance test. The control group only takes the performance test. Both groups have been fulfilling their duties. This pilot study will give an indication if exercise does or doesn't increase performance.

The second study involves testing different type of astronaut underwear. There are four systems: AFS-2, FlexComp - CF, FlexComp - PC, and the Exmocare Watch, which record the subject's physiological signs (i.e. heart rate, skin conductance, and respiration). So far both days of testing have gone well. NASA will take this information and validate their newer monitoring system.
