Space Mountain: Mission 2 is a roller coaster-type attraction located in Discoveryland and is themed around a journey into space.

The original attraction opened on June 1, 1995, Space Mountain was the first roller coaster to feature a Synchronized On-Board Audio Track and was originally themed around Jules Verne's classic 1865 novel From the Earth to the Moon.

Unlike other Space Mountains found around the world, this version has a grander and more detailed appearance, with a huge dominating Columbiad Cannon and a plate and rivet exterior, in keeping with Discoveryland's retro-futuristic theme. It is the only Space Mountain to feature inversions and a section of the ride outside the mountain, that being the station and cannon.

The original version of the ride, De la Terre à la Lune, closed in January 2005 and the theme was changed to Mission 2, planned as a continuation rather than replacement of Verne's classic, where the rider is taken further into space on a new adventure. The track remains unaltered.

The Columbiad cannon blasts off and uniquely launches trains upwards at a 32 degree angle before dropping over the crest of the lift hill to descend back to earth. Look left as you are launched from the Columbiad cannon and catch a breathtaking view of the park. The ride can be rather rough at times as it thunders through it's inversions, twists and turns.
