NASA astronaut Terry Virts (right), Expedition 42 flight engineer and Expedition 43 commander, participates in a camera review training session at NASA's Johnson Space Center. Virts is wearing a sensor on his forehead which is used on the Circadian Rhythms Experiment. This experiment examines the hypothesis that long-term spaceflights significantly affect the synchronization of the circadian rhythms in humans due to changes of a non-24 hour light-dark cycle. Crew instructor Steve Berenzweig assists Virts.
