>How Space Elevators Will Work
>
>When the Space Shuttle Columbia lifted off on April 12, 1981,
>from Kennedy Space Center, Fla., to begin the first space
>shuttle mission, the dream of a reusable spacecraft was
>realized. Since then, NASA has launched more than 100 missions,
>but the price tag of space missions has changed little. Whether
>it is the space shuttle or the non-reusable Russian spacecraft,
>the cost of a launch is approximately $10,000 per pound ($22,000
>per kg).
>
>While the space shuttle is reusable, missions are still very
>infrequent and expensive, with each launch costing an estimated
>half a billion dollars. A new space transportation system being
>developed could make travel to Geostationary Earth Orbit (GEO) a
>daily event and transform the global economy.
>
>A space elevator made of a carbon nanotubes composite ribbon
>anchored to an offshore sea platform would stretch to a small
>counterweight approximately 62,000 miles (100,000 km) into
>space. Mechanical lifters attached to the ribbon would then
>climb the ribbon, carrying cargo and humans into space, at a
>price of only about $100 to $400 per pound ($220 to $880 per
>kg).
>
>In this article, we'll take a look at how the idea of a space
>elevator is moving out of science fiction and into reality.
