A space elevator is a proposed structure designed to transport materials and people from the surface of the Earth to space. It consists of a long cable anchored to the Earth and extending into space, with a counterweight at the other end. This innovative concept aims to reduce the cost of launching payloads into orbit compared to traditional rocket launches. The idea of a space elevator was popularized by physicist Arthur C. Clarke in his novel 'The Fountains of Paradise.' If realized, it could revolutionize space travel and enable more frequent access to low Earth orbit for scientific research, satellite deployment, and even tourism.
