Follow astronaut Scott Kelly in space and his identical twin, Mark Kelly, at home on Earth. The two-part program tells the story of what it takes, mentally and physically, to spend a year in space and then, using what NASA has learned from the Kelly brothers, what it means for humanity as we journey to Mars and beyond.
