1.1 Introduction A space elevator is a proposed method of space transportation system (ISEC, 2012). Currently, we use rocket propulsion as our transportation system to deliver payloads to their destination in space. Space elevators are the proposed alternative to rocket propulsion systems. Figure 1.1 (Herox.com, 2014)shows the structure of a space elevator. The reason we are looking for an alternative transportation system to the current rocket propulsion system is that it will enable safer, easier, faster and a lot cheaper means of transportation to space. With our current rocket propulsion transportation system getting into space is very expensive. For example, it costs around $400 million to launch a simple satellite into geosynchronous …show more content…

By far, the biggest obstacle is developing a material strong enough to construct the cable. This is because the heavier the cable, the more weight it has to support and the more stress it has to endure. Therefore, a material is needed which is incredibly strong, super flexible and exceptionally light weight at the same time. There are two materials which could potentially fit the criteria and this report will examine their feasibility in developing a space elevator. There are two possible candidates at the moment, carbon nanotubes and diamond nanothreads which we will discuss in section 2.0. 1.2 Literature Review 1.2.1 The Eiffel Tower Inspiration – Konstantin The idea of a space elevator is not entirely new. It was first envisioned in 1895 by a Russian Scientist, Konstantin (Cain, 2013). He was inspired by the landmark of the French nation, the Eiffel Tower in Paris. He theorised a similar tower could be built from the ground all the way up to the geostationary orbit (Goh, 2013). 1.2.2 Yuri N. Artsutanov Artsutanov suggested the usage of a geostationary satellite as the main base. The satellite would carry a counter weight which would be extended away from earth and from the geostationary orbit a cable will be lowered down to Earth. His idea was published in the 1960s following an interview on the Sunday supplement of Komsomolskaya Pravada (Artsutanov ,
