Space Mountain in Disney’s Magic Kingdom Park celebrates its 50th anniversary Wednesday and the park is set to celebrate. Throughout the night of January 15, the exterior of Space Mountain will bathed in a golden glow visible throughout the Magic Kingdom.

Walt Disney wanted to build Space Mountain at Disneyland a decade before the indoor roller coaster forever altered the skyline of the Magic Kingdom a few years after the debut of the Florida theme park. Disney’s Magic Kingdom theme park will celebrate the 50th anniversary of Space Mountain on Wednesday, Jan. 15.

This week, 50 years ago, marked the launch date for Disney’s adventure into the final frontier of space with their Space Mountain attraction.

A cultural touchstone, the dark ride opened to the public on Jan. 15, 1975, three years and three months after the Magic Kingdom’s debut.

Space Mountain is one of the most recognizable theme park attractions around the world, but here’s what you may not know about the beloved ride.

• Jan. 15, 1975: Space Mountain opened at a cost of $15 million, the Sentinel reported, “an amount more than the whole cost of Disneyland, built in 1955.” Astronauts Scott Carpenter, James Irwin and Gordon Cooper posed with Mickey Mouse, who is decked out in a spacesuit.

This year marks the 50th anniversary of Space Mountain at Walt Disney World and some brand new pins are available.

Blasting off from Magic Kingdom Park at Walt Disney World Resort, Space Mountain has delighted guests with a thrilling adventure through the cosmos since its grand opening on January 15, 1975. For 50 years and counting,
