Spaceship Earth
Epcot
Disney World

This iconic and symbolic structure of Epcot is an 18-story geodesic sphere that takes guests on a time machine themed experience using the Omnimover system.

Spaceship Earth is not a geodesic dome. It is a complete sphere, supported on legs.

The cladding was designed so that when it rains, no water pours off the sides onto the ground. (All water is "absorbed" through one inch gaps in the facets and is collected in a gutter system - and finally channeled into the World Showcase Lagoon.)

Geometrically, Spaceship Earth is a pentakis dodecahedron, with each of the 60 isosceles triangle faces divided into 16 smaller equilateral triangles. Each of those 960 flat panels is sub-divided into four triangles, each of which 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 of them, with 954 partial or full flat panels.
