Space Mountain is a space-themed indoor roller coaster attraction located at five of the six Disneyland-style Disney Parks. Although all five versions of the attraction are different in nature, all have a similar conical exterior façade that is a landmark for the respective park. The original Space Mountain coaster opened in 1975 at Walt Disney World Resort in Florida. There are two tracks within this attraction, Alpha and Omega, which passengers can choose from. Other versions of the attraction were built at the other Disney parks (all except for the Shanghai Disneyland Park).
