HUBBLE 3D enables viewers to journey through distant galaxies to explore the grandeur and mysteries of our celestial surroundings, and accompany space-walking astronauts as they attempt the most difficult & important tasks in NASA's history. Traveling around the planet at 17500 miles per hour, the astronauts of the space shuttle Atlantis have only one chance to secure Hubble's future. If they fail, we lose our window into galaxies so distant, their light has taken billions of years to reach us.
