The opening of Euro Disneyland in April 1992 marked a significant change in the design of Tomorrowland. Known as Discoveryland, the land took on a retro-science-fiction style inspired by some of Europe's greatest writers, such as Jules Verne and H. G. Wells. As such, Orbitron's central axis resembles a bronze 19th century rotating planetarium instead of a rocket. This concept was later exported to the attractions at both American theme parks when they were renovated later in the 1990s. This was also the first version of the attraction to be installed at ground level instead of atop an elevated platform.
