European Space Agency astronaut Alexander Gerst, Expedition 40 flight engineer, works with samples and hardware for a combustion experiment known as the Burning and Suppression of Solids (BASS) in the Microgravity Science Glovebox (MSG) in the Destiny laboratory of the International Space Station. He is wearing a Drager 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 humans due to changes of a non-24 hour light-dark cycle.
