Space Mountain is a steel roller coaster attraction in Tomorrowland at Disneyland in Anaheim, California. After the success of the Magic Kingdom's Space Mountain, the Imagineers made plans to build another on the United States West Coast. The ride opened on May 27, 1977, ten years after the original plans were made, and after Walt Disney's death. Originally, Space Mountain did not have a Synchronized On-Board Audio Track (SOBAT), but after the completion and success of Space Mountain: De la Terre à la Lune at Disneyland Paris, a soundtrack arranged by Dick Dale was added to the ride in 1996, then a new soundtrack by Michael Giacchino added for the 2005 reconstruction.

"The 'interior orbit' of rockets on Space Mountain allowed passengers to blast off regardless of weather conditions. The controlled lighting also allowed for spectacular special effects. This scale model was used to study the elaborate track layout and positioning of show elements." - Walt Disney Imagineering 1975 - plastic, paper, mat board, plaint
