Japanese space elevator already in space !
The future tests announced by the specialists of Shizuoka University (Shizuoka University). They promised before at the end of September 2018 to put into orbit the prototype of the space elevator and check whether it will work there. In space, a space elevator will be delivered by the H-2B rocket of the Japanese space agency (JAXA).
A space elevator is a system that will be able to lift loads and people from the surface of the Earth into orbit. And then on – as much on the moon. Lift – in special cabs or containers, moving along a cable stretched into space.
About plans to build something, such grandiose in 2012 announced the Japanese company “Obayashi” (Obayashi Corp). It was threatened that it would put the space transportation system into operation by 2050. Then somehow quieted down – about the progress of work or research, for several years nothing was heard. But, as it turns out, the “lifters” did not sit idle all this time. The same prototype, prepared for shipment to orbit, was created with their participation.
As the Japanese explained, the ready system should look something like the cable will connect the platform on the Earth with the orbital station – such a counterweight. The platform will be located in the ocean near the equator, the counterweight – at an altitude of 96,000 kilometers. On the rope will go lifts – elevators. Most of the way they will rise due to the centrifugal force arising from the rotation of the Earth – reaching a height of 36 000, the elevators themselves will rush to the station.
Since the center of gravity of the system will be located in the geostationary orbit, the entire “elevator economy” will rotate with the Earth – just at its speed. Orbital station – the “top floor” of the space elevator – will also, accordingly, stay in one place.
A grandiose structure, perhaps, will appear in the future – maybe even by 2050. But while the Japanese are planning to test a much more modest device – a space elevator measuring 6 X 3 X 3 centimeters. The prototype, to put it mildly, is miniature – a little more than a matchbox. And the cable, according to which, he will move a little – just 10 meters in length.
The Japanese want to pull a cable between two mini-satellites and put an elevator box on it, equipped with an engine. The experiment will be taken by television cameras. Such tests will be conducted for the first time directly in space.
For a real space elevator, the firm intends to “weave” a cable of carbon nano tubes that are ten times stronger than steel and hundreds of times lighter.
AND AT THIS TIME
Americans are going to ride on a space elevator to a skyscraper hanging from an asteroid from a height of 50 thousand kilometers
A futuristic project called Analemma Tower was offered by American architects from Clouds Architecture Office, famous for their development of houses that could be built on Mars.
The current idea is to build the highest skyscraper on Earth. But to build so that he does not rely on her – on Earth.
Architects intend to hang the building from the sky – from a height of 50 thousand kilometers, attaching it to the asteroid. The asteroid will be located on the so-called geostationary orbit, and the cables will be sent down from it, which will begin to hold the structure stretching to the surface of the planet. In fact, the skyscraper will become a huge autonomous city, which will spread not as wide as most of today’s cities, but skyward. At an unprecedented height …
Ideas are ours!
The idea of a space elevator for more than 120 years. In 1895, inspired by the Eiffel Tower, the founder of astronautics Konstantin Tsiolkovsky in one of his articles described a huge structure with a rope stretched to the “Heavenly Palace.” There it was necessary to climb the elevator, then to fly further into space.
In the late 1970s, the idea of a space elevator was picked up and developed by British science fiction writer Arthur Clark in the novel “Fountains of Paradise”. And in the afterword thanked the newspaper “Komsomolskaya Pravda”, in which July 31, 1960, was published an article “In space – on an electric locomotive” and soon translated in the West. She inspired Clark.
