Scott Kelly

In unusual circumstances, scientists from different countries work together to achieve a common scientific goal. Locked in their spinning space lab, they are isolated from the world — family and friends - and can only watch from the outside as life on Earth continues without them. The space station is a monument not only to the weaknesses of humanity, but also to its ability to do the impossible for the sake of life in space.

Meet the growing, worldwide community of theorists who defend the belief that the Earth is flat while living in a society who vehemently rejects it.

Twin astronauts Scott and Mark Kelly were separated for almost a year, undergoing intensive measurements when one was in space and one was on Earth. But that was only the beginning of their scientific odyssey. "Beyond A Year in Space," PBS and Time's follow-up documentary to last year's — which followed Scott Kelly from launch to landing — chronicles Kelly's return to life on Earth and the extensive medical testing the duo undergo to determine exactly what changes have occurred as a result of his record-breaking stay on the International Space Station. The documentary also follows two new astronauts, Jessica Meir and Victor Glover, training to go even further.

Follow 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.
