ISS036-E-024483 (23 July 2013) --- European Space Agency astronaut Luca Parmitano, Expedition 36 flight engineer, holds a bag while performing evening prep work in the Kibo laboratory of the International Space Station. Parmitano is wearing a Thermolab Double 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 human beings due to changes of a non-24 hour light-dark cycle.
