Spaceship Earth is a dark ride attraction at the EPCOT theme park at Walt Disney World in Bay Lake, Florida. The geodesic sphere in which the attraction is housed has served as the symbolic structure of EPCOT since the park opened in 1982. The 15-minute ride takes guests on a time machine-themed experience, demonstrating how advancements in human communication have helped to create the future one step at a time. Riding in Omnimover-type vehicles along a track that spirals up and down the geodesic sphere, passengers are taken through scenes depicting important breakthroughs in communication throughout history—from the development of early language through cave paintings, to the use of hieroglyphs, to the invention of the alphabet, to the creation of the printing press, to today's modern communication advancements, including telecommunication, mass communication, and the internet. An opening day attraction, the ride has been updated three times—in 1986, 1994, and 2007, when the attraction became part of Spaceship Earth Pavilion. A fourth update of the attraction was planned for the early 2020s but was indefinitely delayed due to the COVID-19 pandemic.
Structure
The structure is similar in texture to the United States pavilion from Expo 67 in Montreal but, unlike that structure, Spaceship Earth is a complete sphere, supported by three pairs of legs. The architectural design was conceived by Wallace Floyd Design Group. The structural designs of both Expo 67 and Spaceship Earth were completed by Simpson Gumpertz & Heger Inc. of Boston, Massachusetts. Geometrically, Spaceship Earth is derived from the Class 2 geodesic polyhedron with frequency of division equal to 8. Each face of the polyhedron is divided into three isosceles triangles to form each point. In theory, there are 11,520 total isosceles triangles forming 3840 points. In reality, some of those triangles are partially or fully nonexistent due to supports and doors; there are actually only 11,324 silvered facets, with 954 partial or full flat triangular panels. The appearance of being a monolithic sphere is an architectural goal that was achieved through a structural trick. Spaceship Earth is in fact two structural domes. Six legs are supported on pile groups that are driven up to 160 feet (49 m) into Central Florida's soft earth. Those legs support a steel box-shaped ring at the sphere's perimeter, at about 30 degrees south latitude in earth-terms. The upper structural dome sits on this ring. A grid of trusses inside the ring supports two helical structures of the ride and show system. Below the ring, a second dome is hung from the bottom, completing the spherical shape. The ring and trusses form a table-like structure which separates the upper dome from the lower. Supported by and about three feet off the structural domes is a cladding sphere to which the shiny Alucobond panels and drainage system are mounted. The cladding was designed so that when it rains, no water pours off the sides onto the ground. All water is collected through one-inch gaps in the facets into a gutter system, and the water is channeled into the World Showcase Lagoon.
History
Design and construction The structure was designed with the help of science fiction writer Ray Bradbury, who also helped write the original storyline for the attraction. The term "Spaceship Earth" was popularised by Buckminster Fuller, who also popularized the geodesic dome. Construction took 26 months. Extending upwards from the table are "quadropod" structures, which support smaller beams which form the shell of the steel skeleton. Pipes stand the aluminum skin panels away from the skeleton and provide space for utilities. A small service car is parked in the interstitial space between the structural and cladding surfaces, and it can carry a prone technician down the sides to access repair locations. The shop fabrication of the steel (done in nearby Tampa, Florida) was an early instance of computer-aided drafting and materials processing. Spaceship Earth was originally sponsored by the Bell System from 1982 until 1984, when it was broken into smaller companies and its parent company, AT&T, became an independent company. AT&T sponsored Spaceship Earth from 1984 until 2004. From 2005 until 2017, the German company Siemens was the sponsor of Spaceship Earth. As of 2025, the ride currently has no sponsor. The private sponsor lounge, located on the second floor above Project Tomorrow, was repurposed into an adult only lounge called GEO-82, which opened June 4, 2025. Its name is based on the type of structure and the year EPCOT opened. During Epcot Center's opening ceremony William Ellinghaus, then president of AT&T, dedicated Spaceship Earth and stated: "Now as you will soon see, Spaceship Earth’s theme is communications, civilization and communications from Stone Age to Information Age, and I therefore think it is very fitting that we dedicate Spaceship Earth to all of the people who have advanced communications, arts, and sciences, and in so doing have demonstrated that communications is truly the beginning of understanding."
Updates and history The opening day version of the attraction featured narration by actor Vic Perrin. This version featured a network operations center with a data map of the United States in the modern telecommunications section. The top of the sphere featured a large lighted space station with two astronauts working on satellites and a woman sitting in the station operating controls. During the final descent, vehicles passed several monitors showing various events and activities. This version of the ride closed on May 25, 1986.
