Walt Disney sketched the original design concept for Epcot Center, including Spaceship Earth. Disney wanted a unique structure that would be instantly recognizable around the world. The central figure of Disney’s Millennium 2000 celebration, Spaceship Earth has become the symbol that Walt Disney envisioned. While geodesic domes had previously been constructed, Spaceship Earth was the first large-scale complete geodesic sphere ever built. SGH was the structural engineering and prime consultant for the project.
