| Former Russian cosmonaut Sergei Avdeyev, the last human to spend a year or more in space on a single spaceflight, discussed the challenges facing NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko during their upcoming year aboard the International Space Station. NASA Public Affairs Officer Rob Navias conducted the interview with Avdeyev in Moscow in November 2014. Avdeyev, who ranks third on the all-time list for most time in space with 748 days in orbit on three spaceflights, spent 380 days on the Russian Mir space station from August 1998 to August 1999. |
