Abstract:
Currently all space agencies are completely dependent on rockets to get into space. space elevator can provide the high-volume, low-cost transportation system that will be required for the future space activities mankind hopes for. A system that may have the required traits , space elevator. The space elevator, a cable that can be ascended from Earth to space, is unlike any other transportation system for getting into space, its is a proposed structure designed to transport material from a celestial body's surface into space. which involve traveling along a fixed structure instead of using rocket powered space launch. The concept most often refers to a structure that reaches from the surface of the Earth on or near the Equator to geostationary orbit (GSO) and a counter-mass beyond. Recent conceptualizations for a space elevator are notable in their plans to use carbon nanotube or boron nitride nanotubebased materials as the tensile element in the tether design
