Aboard the International Space Station, Expedition 50 Commander Shane Kimbrough and Flight Engineer Peggy Whitson of NASA fielded questions about life and research on the orbital laboratory during an in-flight conversation with aviation industry experts. The conversation between the astronauts, NASA Acting Administrator Robert Lightfoot, Marc Garneau, the Canadian Minister of Transport and a former astronaut and president of the Canadian Space Agency, and Carol Hallett, counsel to the U.S. Chamber of Commerce, took place March 2 at the chamber’s annual Aviation Summit Conference in Washington, D.C. Kimbrough, who arrived on the station last October, is scheduled to return to Earth April 10 while Whitson, who launched to the outpost last November, is in the midst of her third long duration mission on the complex.
