Space elevator



















space elevator































Humankind has always been interested in discovering alien space. The greates accomplishment from outer space is the International Space Station (ISS), which goes around the Earth 16 times in a day with merely 27 000 km/h . Not all of us are very happy when we talk about flying outer space. Althoug , Japanese are planning to travell outer space with an elevator and for good reason because they’ll have to cover only 36 000 km. How the’ll do this? They want to connect/link a geostationary satellite to a fixed point on Earth using very resistant and very light cables. In order to achieve this, they must build a counterweight positioned 100.000 km from Earth. The cables will be made of carbon nanotubes, which are considered to be the strongest and most rigid materials on Earth ( a cable of 1 square mm in diameter can sustain 6300 kg). The costs are estimated around less than $10 billion. I don’t know what to think but it doesn’t seem impossible when it comes to japanese. We will know for certain when the construction will be decided upon.
