Similar Canadian company will make a direct lift tower into space (Dok.Thot Technology)
No half-hearted, in order to realize a lift that can lift payloads into space, Japan is allocating US $ 10 billion to realize one of these ambitious projects.
Actually, the idea related to space elevator has been around since 100 years ago. The theoretical astronautics a Russian named Konstantin Tsionkovsky had put forward the idea to build a tall tower thousands of kilometers to reach the horizon orbit.
Subsequently, in 1960, Yuri Artsutanov, a student from Leningrad Technology Insititute had also put forward the idea to create a cable that connects the point from the equator to the geostationary orbit at 35 786 km so that its orbit can still adjust the location of the earth.
There is also a science fiction writer named Atrhur Clark ever wrote down ideas related to outer space elevator. He put forward the idea related to this elevator in his novel The Fountains of Paradise. In 1999, NASA inspired the idea of Clark and his research team named Scientific Research Institute to achieve this goal, at least in the third millennium.
Of the whole idea that there is, no one has been able to be realized to succeed. In 1965, Sergei Korolev, a Russian scholar had conducted experiments with Rocket and Space Corporation Energia related to cable systems in this space.
Unfortunately, in the middle of the workmanship, he died so that the development of this cable is postponed until 20 years later. Various other studies related to this cable system also had to be done by the United States, Italy, and Japan. But, just a few who see the light of the results of this study.
In recent years, research Space Research Institute of the Russian Academy of Science have time to do research related to the manufacture of cable system that can enable us to deliver cargo to the moon.
Results of this study stated that the project uses two cable system, where the 2 wires are in low earth orbit, while 1 cable is in the moon's orbit.
These cables will function like a catapult which dissipates the charge with the help of rotational energy. However, again, these results can not be realized until now.
Japan is the country that is supported by a high technological advances. However, the related idea of making an elevator to space is indeed not an easy thing.
This country should at least be able to make a lighter cable, but has strength and density six times lighter than steel. Industrial new technology capable of making carbon nanotubes of diameter of 1 mm, which can carry 60 metric tons of payload.
Even this was still exceed the limits of what is needed to make the elevator into space. In addition, space junk and the natural vibrations generated from the cable to lift into space could also impair the durability of the cable itself.
On the other hand, this lift may also have a battery with a power that can support the process of transporting cargo.
This is clearly going to be a challenge for Japan. But apart from that, the elevator into space this will be a spectacular discovery in the 21th century when Japan was able to realize them. (cnnindonesia)
