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.

Can Homo sapiens evolve into Homo spatius? For over 50 years now, we have been testing our human nature in our effort to conquer outer space, and still 30 years away from a possible human exploration of Mars, a question remains: Can our body take such travels? Will it ever adapt? Combining human adventure and the exploration of the human body, this film offers unique insights into the physical and psychological effects of space travel on the Astronauts and measures the impact on medical sciences.
