The Space Elevator is the most promising Space Transportation system on the drawing boards today, combining scalability, low cost, qualify of ride, and safety to deliver truly commercial-grade space access-practically comparable to a train ride to space. A space elevator is a proposed structure designed to transport material from a celestial body's surface into space.[1] All studies indicate that the idea, outrageous though it appears at first sight, is theoretically feasible and that its practical realization could follow from the mass-production of high-strength materials now known as laboratory curiosities This paper is a semi-technical survey of the expanding literature of the subject. Also describe the current methods used for space elevator and merits and demerits of current method and give some proposed method’s to overcome the limitation of recent method’s to build a Space elevator. As a result of which save access to space-no explosive propellants or dangerous launch or re-entry.
