1 Why I Chose Space Elevators Implementation of a “space elevator” would revolutionize man’s accessibility to space the same way the automobile changed our mobility on earth’s surface. In fact, the true impact is probably beyond anyone’s speculation, much as Henry Ford didn’t truly know what he was starting. My research is inexorably linked to satellites, so I have more than a casual interest in how those bits of metal and silicon get launched into space.

5 http://www.alumni.umn.edu/ Russian scientist, Konstantin Tsiolkovsky, was inspired by the Eiffel Tower in 1895. In 1978, science fiction author, Arthur C. Clark, wrote about carbon fiber materials that would fulfill Tsiolkovsky’s vision. New Ideas and Concepts for Space Access

6 r = 42,170 km v = 3070 m/s The weight of the cable and climbers becomes important in determining the counterweight. http://hyperphysics.phy-astr.gsu.edu Mechanics of Space Elevators

7 Photo from Wikipedia – http://en.wikipedia.org The tether must be able to withstand the Earth’s atmosphere and the space environment. High voltages and currents develop as it cuts through the Earth’s magnetic field. It must be both extremely light- weight and stronger than any material now used in aerospace construction. Building a Tether

8 Photo from Georgia Institute of Technology http://gtresearchnews.gatech.edu Carbon nanotubes and carbon nanotube composite materials show great promise for use in developing a space elevator. Potentially 100x stronger than steel, flexible like plastic. Long chains could be braided together, short chains encased in a polymer matrix. Nanotubes Get Involved
