Changes

The structure of the pavilion itself remained unchanged until 1999, when a large Mickey hand holding a wand was added to the top of Spaceship Earth. The wand was dedicated "2000" in celebration of the new millennium, before the dedication was changed to "Epcot" in 2001. The Mickey hand and wand remained atop Spaceship Earth until it was removed in 2007, just in time for Epcot's 25th anniversary.

Throughout its history, Spaceship Earth has served as a historical tour of the history of communication. The pavilion was first refurbished in 1986, with subsequent refurbishments taking place in 1994 and 2007. Following each refurbishment, the attraction has been given a new script, a new narrator, and a new finale. When Spaceship Earth opened in 1982, it was sponsored by Bell Systems, before the company was broken up and AT&T (Bell's parent company) assumed sponsorship of the pavilion. AT&T continued to sponsor the attraction until 2004, which paved the way for Siemens to assume sponsorship in 2007. Listed below is a more detailed description of the differences between the four versions of Spaceship Earth.

The queue for the original Spaceship Earth attraction began with guests entering the pavilion, and walking up a short ramp. On the walls on either side of guests, large two posters showed Spaceship Earth at night, read "Ride the Time Machine from the Dawn of Civilization to the Beginning of Our Tomorrow. SPACESHIP EARTH.". Nearby, a large mural showed astronauts working on a satellite, with Earth in the background. The mural was framed with small pictures depicting cavemen, Romans, Egyptians, the printing press and finally modern humans. After passing through the queue guests would board small blue ride vehicles, beginning the attraction itself.
