Space Elevator

A space elevator, commonly referred to alternatively as a "space tether," appearing in the video game "Halo" is the term given to an immense structure which is used to ferry large loads of materials into space. Space elevators generally consist of large structures of carbon nanofiber which span straight up from the ground, thousands of kilometers high, ending at stations in space. Vehicles using the structure derive their power from strands of superconducting material. Space elevators are only known to have been constructed by humans since the 24th century.
