Chamitoff works with the MELFI in the U.S. Laboratory during Expedition 17

ISS017-E-017539 (27 Sept. 2008) --- NASA astronaut Greg Chamitoff, Expedition 17 flight engineer, works with the Minus Eighty Degree Laboratory Freezer for ISS (MELFI) as part of the Nutritional Status Assessment (NUTRITION) experiment in the Destiny laboratory of the International Space Station. MELFI is a low temperature freezer facility with nominal operating temperatures of -80, -26 and +4 degrees Celsius that will preserve experiment materials over long periods. The results of the Nutrition experiment will be used to better understand the time course effects of space flight on human physiology.
