Hyperspace Mountain Hyperspace Mountain is a " Star Wars " - themed seasonal overlay to the roller coaster attractions at three Disney Parks . The version opened as part of the Season of the Force event on November 14 th , 2015 , and the version opened June 11 th , 2016 , as part of the Star Wars : Tomorrowland Takeover event . On May 7 th , 2017 , the update opened in . Utilizing the animation projection infrastructure used in the ride ' s earlier Halloween - themed Ghost Galaxy overlay , laser effects , and a newly recorded arrangement of assorted John Williams scores performed by the London Symphony Orchestra , the attraction put guests into a dogfight between X - wing starfighter s and TIE fighters at the start of the Battle of Jakku . On April 20 th , 2017 , the Disney Parks Blog announced that the Disneyland version of the ride would return to its original " classic " Space Mountain format on June 1 st . Synopsis . The attraction queue is mostly left in its standard form , though graphics and a brief pre - show and safety film set up the simple story and place Space Mountain ' s space station setting into the role of a New Republic base . The Hong Kong installation added an X - Wing hangar mockup to an outdoor portion of the queue . Admiral Gial Ackbar sends out a brief holo - transmission to a group of reconnaissance pilots to investigate an Imperial Star Destroyer near Jakku . He also announces the 77 Squadron — flying as " Blue Squadron " — will provide support for the mission . Much of this back story is not mentioned in the Paris version of the ride , since there is only a safety video featuring a human woman , and no appearance by Ackbar . After boarding the reconnaissance vessel ( portrayed by Space Mountain ' s sled - like rocket vehicles ) , the recon team and Blue Squadron make a jump through hyperspace . Upon arrival at Jakku , a group of TIEs ambushes the team . The recon vehicle ducks and weaves its way through the dogfight and assorted laser - fire from either side . With the TIE squadron destroyed , Blue Squadron is able to make a critical destructive hit on the Star Destroyer ' s bridge area and make a quick jump through hyperspace back to the base . Behind the scenes . Space Mountain originally opened at Disneyland on May 27 th , 1977 , two days after first premiered in theaters ( Walt Disney World ' s version had opened two years earlier ) . In 2005 , as part of Disneyland ' s 50th Anniversary , the attraction underwent a significant overhaul including a new sound system and digital projection infrastructure that would allow for alternative versions of the attraction . The first variation was Rockin ' Space Mountain , followed a few years later by a more involved Halloween overlay borrowed from Hong Kong ' s park , Space Mountain Ghost Galaxy . That more successful overlay added additional projection hardware in 2007 . In 2015 , to promote " " and act as a stop - gap until the to Disneyland opened , Disney announced a promotional event called " Season of the Force " located in Tomorrowland , consisting of an " The Force Awakens " themed - update to " " , a clip show of the entire saga entitled " Path of the Jedi " , an update to the Jedi Training Academy entitled Trials of the Temple , the Star Wars Launch Bay exhibit , and " Hyperspace Mountain " . Disney Imagineers consulted with Lucasfilm Story Group to ensure " Hyperspace Mountain " would fit into the canon timeline and decided to tell the story of the space battle portion of the Battle of Jakku , which also appeared in the novel " Lost Stars " and the " Star Wars Battlefront " video game . New starfighter animation and musical arrangements of John Williams ' tracks were produced for the overlay and the temporary attraction opened at Disneyland on November 14th , 2015 . The 77 Squadron takes its number from 1977 , both the year when " Star Wars " : Episode IV " A New Hope " first premiered and when Space Mountain first opened at Disneyland park .
