Synopsis: In May 2009, the crew of the Space Shuttle Atlantis launched a mission to make vital repairs and upgrades to the Hubble Space Telescope, the world's first space-based optical telescope. An IMAX camera captured the stunning footage of the five intricate spacewalks required, as well as close-up images of the effort to grasp the orbiting telescope with the shuttle's mechanical arm at 17,000 MPH - and an unexpected problem that could sabotage the entire mission.
