  • Retired NASA astronaut Scott Kelly had four missions in space, including a 340-day trip aboard the International Space Station in 2015-2016.
  • On our “Success” podcast, he describes himself as a distracted kid who figured out his life later than his identical twin brother Mark, who also became an astronaut.
  • He shared some of his best moments in space, like seeing the entirety of planet Earth, as well as the worst, being helpless when his sister-in-law Gabrielle Giffords was shot in 2011.

When Scott Kelly talks about flying into space, he sounds like a guy talking about his favorite hobby, with the same tone someone would use for golf or fishing.

As a NASA astronaut, Kelly made four trips to space, including spending 340 days onboard the International Space Station. Meanwhile, his identical twin brother — and fellow astronaut — Mark was on Earth. Since then, scientists have been watching how differently the two have aged. In March, they said that Kelly’s DNA had changed by 7% following his year-long trip.
