of an outdoor scene. To create the effect, scale models were built and a camera swept across the futuristic terrain. The models were some of the largest ever created at the time. The model for the desert sequence, for example, was long. The visual effects were filmed in a hangar at the Burbank airport. Produced in 1983 by 30 model makers, it took over a year to build and shoot the three segments. The exit corridor of the ride originally featured the mural The Prologue and the Promise by renowned space artist Robert T. McCall.

Walt Disney World Resort Mission: SPACE A number of tributes to Horizons can be found throughout its successor attraction, Mission: SPACE. The center of the gravity wheel in the queue has the attraction logo, and a stylized version also appears on the front of the checkout counter in the Cargo Bay gift shop at the exit to the attraction. Also, following the attraction's 2017 refurbishment, a new mural added to the entrance features the space station Brava Centauri orbiting the Earth. Space Mountain When it was refurbished in 2009, Space Mountain included a number of tributes to Horizons in its post-show: One of the bags in the post-show for the ride (located on guests' left at the start of the exit walkway) features the words "Mesa Verde" written on it. The undersea post-show scene after the desert scene is reminiscent of a scene in Horizons. This scene is the only post-show scene to be completely new in refurbishing Space Mountain. The flatscreen display in the new scene describes it as "20,000 Light Years under the Sea," a pun on "20,000 Leagues Under the Sea," which is a reference to the defunct Magic Kingdom attraction 20,000 Leagues Under the Sea: Submarine Voyage. The robot butler and futuristic city skyline, which is the last post-show diorama, are similar to a scene in Horizons. Walt Disney: One Man's Dream Some of the props used in
