The documentary reveals the behind-the-scenes action with the teams of SpaceX engineers, NASA employees and scientists as they fulfil the SpaceX mission to “fly, test and fix” their way to the International Space Station – with the goal of eventually flying to the moon and to Mars. The Falcon 9 rocket and Crew Dragon Capsule will send U.S. astronauts into space for the first time since the Space Shuttle was retired in 2011.
