The main purpose of the space elevator, what is the principle of the space elevator

With current technology, it's not that easy to get into space, and if we want to observe planets in space, the most realistic way is to become an astronaut or become a billionaire.

You can compare Earth to this athlete, and the shot put he is about to throw through the spinning acceleration is the equivalent of a towering space elevator counterweight.

The main principle of operation of this "space elevator" is actually not complicated, the capsule containing the cargo is sent back to Earth by a particularly strong cable 30 kilometers long. Although the cable is very long, the weight of the stove does not exceed 6 kg and it needs to be made of special materials. When it enters the atmosphere, the cable burns, and the cargo continues to slowly descend to Earth with the balloon on its back.

Space Elevator: The space elevator, which is a component of the space elevator, consists of the elevator itself and a set of gripping devices installed on Earth. It is a new type of three-dimensional transportation system.

Finally, there is the space station at the other end of the cable. The space station is a must, because to offset the weight of the cables. In fact, the envisioned space station is not placed in the orbit of a geosynchronous satellite, but in a slightly higher position, because the entire cable and the entire center of gravity of the space station must be placed in geosynchronous orbit so that it will not deviate.

The construction of a space station can be quite cumbersome, as the position of the space station is constantly adjusted as the cables are thickened. But if all goes well, in the end, the space station can be used as a launch pad for humans to travel to other planets, in addition to being a counterweight!

The U.S. space elevator race has ended three times with no one reaching the standard (two meters per second of ascent), but the U.S. is serious about continuing to push the technology forward. Japan, on the other hand, is invested.

$100 million to develop its own space elevator technology, hoping to take the lead in this field. Whoever builds the first space elevator first is almost equivalent to winning the ticket to colonize outer space, so it is conceivable that when technology advances to a certain extent, it will inevitably trigger a new wave of space races.

What is the principle of the space elevator?

The principle of the space elevator is very similar to that of ordinary elevators in life.

The principle of the space elevator is not complicated, and it is very similar to the ordinary elevator in life. The first base simply builds a space station in geosynchronous orbit and connects it to the ground with some kind of rope that is long enough and strong enough, and the rope is taut under the interaction of gravity and centripetal acceleration. Astronauts, passengers, and cargo can go straight into space along the rope through an elevator car-like lifting cabin, so that there is no need to rely on complex space tools such as rockets and spaceships, which can be described as a veritable Tower of Babel.

The idea of a space elevator was first proposed by Russian scientist Konstantin Tsiolkovsky in 1895, who proposed to build a space castle in geostationary orbit and connect the ground to the castle with a cable to achieve space transportation.

The concept of the space elevator was conceived by the famous pioneer of rocket science Tsiolkovsky, a sky castle built on top of a giant tower, and it was Arthur Clarke who really described the problem from a technical point of view.

According to the British "Daily Mail", science fiction writer Arthur C. Clarke described the idea of a space elevator in his 1978 book "Paradise Spring", which allows people to take the elevator to space sightseeing and transport goods. The body of the space elevator is a cable that permanently connects the space station to the surface of the earth, and can be used to transport people and goods from the ground to the space station.

Theoretically, a space elevator could become a reality.

The biggest obstacle to space elevators is materials, and at the moment, enough materials to build a traditional space elevator do not exist, or it is difficult to make the necessary quantities of materials. However, scientists have been studying how to make space elevators a reality using existing technologies and materials.

Because the space elevator has to raise a steel cable from the ground to a height of 30,000 kilometers in geosynchronous orbit, but at present, our tallest material, probably a chain made of carbon fiber, can only rise to 200 kilometers at most.

According to Mashable, the most promising approach was proposed by George Zhu, a professor in the Department of Mechanical Engineering at York University, who co-authored a research paper on the idea. The method will involve the use of two cables instead of one, much like a cable car system.

Uses of space elevators:

Space elevators can carry everything from large solar generators to nuclear waste, as well as people. What's more, after the space elevator becomes a reality, the space lift module will not need to carry a lot of fuel into the sky.

It can also use the "space elevator" to transport tourists, and also develop space tourism. The elevator will carry a solar power system, so that the electricity generated will not only support the elevator itself, but also power the earth. The space elevator can also be used as a signal tower to transmit information.
