Astronaut Scott Kelly on his year in space

Astronaut Scott Kelly spent nearly a year aboard the International Space Station as part of a study examining the effects of long-duration spaceflight on the human body. The research, which compared Kelly's biological markers with those of his identical twin brother on Earth, revealed surprising results about telomeres and the impact of space radiation. Kelly is touring Australia in November to share his experiences and the lessons learned from his NASA career.See omnystudio.com/listener for privacy information.
