Space Technology

A space elevator is a proposed structure designed to transport material from a celestial body’s surface into space. The concept of a space elevator dates back to 1895 when Konstantin Tsiolkovsky^[1] proposed a free-standing “Tsiolkovsky” tower reaching from the surface of Earth to geostationary orbit. Most recent discussions focus ontensile structures (specifically, tethers ) reaching from geostationary orbit to the ground. Spaceelevators have also sometimes been referred to as beanstalks, space bridges, space lifts, space ladders, skyhooks, orbital towers, or orbital elevators.
