Space Mountain
Also part of this major "new" Space Mountain was a nighttime transformation of the attraction to "Rockin' Space Mountain", in which the calmer soundtrack of the attraction in daytime hours was replaced at night with a driving rock soundtrack, and different special effects. The original version of Rockin' Space Mountain, called "RockIt Mountain", premiered for Grad Nite 2006 as part of the Happiest Homecoming on Earth.
