Blast off on a high-speed roller coaster through the darkness of outer space in this iconic Tomorrowland attraction. Space Mountain's near-complete darkness amplifies the sensation of speed on this indoor coaster with sharp turns and sudden dips set against a backdrop of stars and cosmic projections. An opening-day classic since 1975, it remains one of Magic Kingdom's most popular thrill rides. The coaster is actually slower than you think — the darkness makes it feel faster. Single-rider seats in rocket-shaped vehicles add to the astronaut experience.
