A space elevator is a device that would carry people, cargo, and power from the Earth into space. The space elevator would be constructed by extending a long cable from the Earth's surface into space; the cable would be held up by a satellite in geostationary Earth orbit. Fat-moving electromagnetic elevator cars would travel along the cable from Earth into space and back.
A space elevator is a proposed structure designed to transport material from a planet's surface into space. Many different types of space elevators have been suggested. They all share the goal of replacing rocket propulsion with the traversal of a fixed structure via a mechanism not unlike an elevator in order to move material into or beyond orbit.
