AstroTwins - Scott Kelly

From Afternoons with Jesse Mulligan, 2:22 pm on 19 January 2015

Scott Kelly is an astronaut who's making history with the help of his twin brother. In March, the American will embark on a mission to live on the International Space Station longer than any other American astronaut. What makes the trip particularly special, is that it could provide answers to how long-term space travel affects the genetic make-up and health of astronauts. Scott's identical twin brother, retired astronaut Mark Kelly, will stay on earth and undergo similar tests to his brother.
