Aboard the International Space Station, Expedition 45 Commander Scott Kelly and Flight Engineer Kjell Lindgren of NASA discussed life and research aboard the orbital outpost in a pair of interviews Oct. 22 with WNYC Radio in New York and CNBC. Kelly is in the seventh month of his year-long mission on the station with cosmonaut Mikhail Kornienko of the Russian Federal Space Agency (Roscosmos), gathering biomedical data that will be valuable in the formulation of a future human mission to Mars. Lindgren is entering the fourth month of his five-month mission on the orbiting laboratory, conducting research and maintenance activities. Kelly and Lindgren will conduct a pair of spacewalks Oct. 28 and Nov. 6 outside the station’s Quest airlock to perform upgrades to station systems.
