A Year in Space

A Year in Space follows astronaut Scott Kelly's 12-month mission on the International Space Station, from launch to landing, as NASA charts the effects of long-duration spaceflight by comparing him to his identical twin on Earth, astronaut Mark Kelly. Beyond A Year in Space introduces viewers to the next generation of astronauts training to leave Earth’s orbit and travel into deep space.
