Opened in 1975, Space Mountain has been an iconic attraction in Walt Disney World’s Tomorrowland for 41 years to the day. In that time, millions of exhilarated guests have enjoyed Space Mountain’s thrilling attraction — hurtling through deep, dark star-filled space. Like many attractions throughout the Magic Kingdom, Space Mountain is not only an E-ticket attraction but it also serves to further the over-arching Tomorrowland story. In its original incarnation, Space Mountain fit nicely into the Space Age Tomorrowland of the late 70s. Similar to 1970’s Tomorrowland, the attraction backstory focused on space exploration. However, when Tomorrowland underwent an extensive retro-futurism refurbishment in the 90s, Space Mountain received a new backstory that supported the land’s new theme of a bustling spaceport.


Regardless of attraction backstory, themed land or Walt Disney park, Space Mountain is truly an Imagineering wonder full of fascinating history and lore. In honor of this mountain’s 41st anniversary, let’s take a look at some entertaining trivia tidbits:

  • There are a total of 30 rocket ship attraction vehicles number 1 through 31. There is no rocket ship numbered 13.
