Today, TIME launches the first two episodes of its newest long form video series “A Year in Space,” following NASA Astronaut Scott Kelly’s historic yearlong mission to the International Space Station. The series will run for a total of ten episodes throughout the next year at the trailer here: 

On March 27, 2015, Kelly took off for a one-year stay at the International Space Station, which will mark a single-mission record for a U.S. astronaut. Over the course of the mission, NASA will also be tracking his identical twin brother, retired astronaut Mark Kelly, studying how both of their bodies change over the course of a year and the effects of long term space travel. TIME follows the journeys of both brothers and their families with the series. 

“A Year in Space” is produced by Red Border Films, TIME’s special news documentary unit.  It is directed by Shaul Schwarz (Narco Cultura), co-directed by photographer and filmmaker Marco Grob (TIME’s Beyond 9/11:Portraits of Resilience), and produced by TIME’s senior multimedia editor Jonathan Woods, who largely spearheaded the project.

Executive producers are Time Inc. Studios’ Mike Beck, TIME Editor at Large Jeffrey Kluger, Time Inc. News and Sports Executive Producer Ian Orefice and TIME Director of Photography and Visual Enterprise Kira Pollack. For Red Border Films, TIME Editor Nancy Gibbs, Managing Editor Edward Felsenthal and Time Inc. SVP of Video J.R. McCabe executive produced.The first episode of “A Year in Space” centers on Scott Kelly as he says goodbye to family and friends before leaving for the mission. In the second episode, he heads to a once secret space center outside Moscow that is now the scene of an unprecedented collaboration between former enemies. Earlier this year, TIME published a cover story by Kluger on the Kelly brothers’ endeavor and Grob photographed the cover image.
