The novel was the first popular account & # 39; idea described by the Russian scientist Konstantin Tsiolkovsky in 1895: the space elevator, system & # 39; Earth to space transportation such as elevators we use everyday but 300,000 times higher.

The appeal & # 39; & # 39 elevators; space comes & # 39; to find potentially much cheaper way to travel into space. It cost more than US $ 160 million to launch a satellite for one journey, but it is estimated that lift the space can & # 39; reduce that to less than US $ 2 million per person per trip.

The basic concept of & # 39; & # 39 elevators; space involves cable anchored to the Earth's surface and connected to & # 39; counterweight to be sent into space. If the cable is long enough – 36 000 km (22 369 miles) or three times the Earth's diameter – will be pulled and carded a steep gravity and centrifugal force.

The theory is that a vehicle can & # 39; then travel along the cable, pushed by the rotational energy of the Earth. It revolutionized travel in space, but the design and discovery & # 39; & # 39 b material; his health enough for the idea is & # 39; a major challenge.

The two satellites launched in Japan & # 39; September in the first experiment to study the movement of the elevator into space, involving a mini-lift cable from a satellite traveling on to another. Yet to report results. China has also carried out tests & # 39; tethering & # 39; space but did not disclose details.

Rocket scientist Tsiolkovsky first established the concept back in 1895, he was thinking celestial castle in space linked to the World by a huge tower. The Russian engineer Yuri Artsutanov took moreover, developed a modern version of & # 39; space & # 39; lift based on the model & # 39; Tsiolkovsky.

The American space scientist and engineer Jerome Pearson published the first technical paper on the concept in 1975, which gained attention among the scientific community. Four & # 39; years later, the writer Clarke scientific idea facilitated by carrying out design & # 39; Pearson in his noble about the space elevator.

Scientists have been trying since then to refine the design and develop new materials to bring the concept closer to reality.

The three biggest challenges to be overcome are buckling, dynamic stability and strength. Scientists believe they can control buckling and dynamic stability with the help of & # 39; satellite, f & # 39; orbit Geostationary at the right altitude, to ensure that the cable does jinġibx & # 39; down from the gravity of Earth or fly & # 39; away.
