A Chat with the One-Year Crew.

Expedition 45 commander Scott Kelly of NASA and flight engineer Mikhail Kornienko of the Russian Federal Space Agency (Roscosmos), discussed the progress of their year-long mission aboard the orbital laboratory with National Public Radio’s “All Things Considered” program and with anchor Lester Holt of NBC Nightly News in a pair of interviews Oct. 7. Kelly and Kornienko are in the seventh month of their mission on the outpost, collecting valuable biomedical data that will be used to formulate a future human mission to Mars. They will return to Earth next March.
