IMAX: Hubble, narrated by Leonardo DiCaprio, takes moviegoers on an unprecedented voyage through distant galaxies to explore the grandeur and mystery of our celestial surroundings. Experience never before seen flights through the farthest reaches of the universe, and accompany spacewalking astronauts on some of the most difficult and important endeavors in NASA's history. 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 observatory, 350 miles above the Earth. On board was an IMAX camera, operated by the shuttle astronauts. It captured stunning sequences of the five intricate spacewalks required to make those repairs, as well as close up images of the effort to grasp the orbiting telescope with the shuttle's mechanical arm at 17,500 mph, and one unexpected problem that threatened to sabotage the entire mission.
