I know that many friends cried in the later stages of watching "The Wandering Earth", but half of the cat cried when they saw the footage of the space elevator lifting.
Listening to the music of the Ah Kun space elevator and looking at the speeding space car, I suddenly felt that Chinese science fiction was about to take off like this elevator. And I, a fan of science fiction movies, was lucky enough to catch up with the lay.
In this issue, half a cat will interpret the "space elevator" in detail from three aspects: origin, operation mode, and elevator structure.

1. Origin
In 1895, Russian rocket expert Knostantin Tsiolkovsky first proposed the concept of a space elevator. He envisioned the construction of a hundred-kilometer-high "Eiffel Tower" and a "sky castle" at the top of the tower, accessible by elevator.

In 1979, Arthur A. Clark first depicted the "Ascending Elevator" in the science fiction novel Fountain of Heaven, a sprawling facility that bridges the open space.
"Fountain of Paradise"
"In the synchronous space station 36,000 kilometers above the equator, a cable is linked to a huge orbital tower on the ground, and because the space station is synchronized with the Earth, the space station is stationary relative to the Earth, so that it can enter space without rockets, and the payload can be greatly improved."
In 2012, our neighbor Japan proposed that a space elevator be built by 2050 to take passengers to an altitude of 36,000 meters. But without the involvement of infrastructure maniacs, I am very concerned.
Plan a conceptual map
In short, so far, the space elevator is only a concept, and it cannot be realized.
In some foreign science fiction works, there have also been space elevators, but the space elevator in "The Wandering Earth 2" is the most complete, detailed, and most likely space elevator that half a cat has seen. Anyway, it's the right taste.
Second, the mode of operation
Space elevator
The space elevator in "The Wandering Earth 2" was built in Gabon, on the west coast of central Africa, on the equatorial line,
It is the tallest building in human history, reaching 90,000 kilometers at its highest point
The main body of the space elevator is a cable structure connecting the space station and the Earth launch platform, which can be used to transport people and goods from the ground to the space station. All the construction personnel and engineering materials of the Ark space station rely on the daily transportation of space elevators to and from the space.
The space elevator's car space is large, which can accommodate many astronauts to and from space, greatly improving the efficiency of commuting. Like a Big Mac on a cosmic highway.
Of course, not everyone can sit casually, passengers must wear pressure suits and oxygen masks, and undergo professional astronaut training to be able to ride the elevator. When the elevator starts to accelerate, most people will experience fainting.
The space elevator adopts segmented power propulsion, which is propelled by an engine at the beginning and ejected like a rocket, and each elevator compartment has 4 to 8 thrusters and 8 cables to guide.
After reaching a certain height, it turns to magnetic grabbing, continues to rise like a normal elevator, and finally docks with the space station
Magnetic gripping
When returning to Earth, in order to cope with the frictional heat through the atmosphere, the elevator capsule will fill the space with water, instantly forming an ice shield, melting the flame into ice. Avoid direct friction between the cabin and the atmosphere, saving return costs.
Fill the bottom with water
Third, the elevator structure

At the bottom is the Boarding Platform, built on the sea.

BETWEEN 2000 KM AND 3600 KM ARE SYNCHRONOUS ORBITAL STATIONS, STATIONS 1 AND 2, AND THEIR CONTROL CENTER IS NEAR THE BOARDING PLATFORM
4,000 km IS THE MATERIAL STORAGE AREA
BETWEEN 4,000 KM AND 7,000 KM, THERE IS THE EXPERIMENTAL AREA
7,000 km IS THE MAINTENANCE AREA
10,000 kilometers away is the Ark space station, which is also the end of the space elevator so far.
The Ark space station is similar to the navigator space station in "The Wandering Earth", and is one of the important plans to accompany the earth, carrying human civilization data and species DNA.
The next long distance remains undeveloped.
At kilometer 90,000 is the balance ship COUNTERWEIGHT DROPSHIP, the highest point of the space elevator
Keep it balanced
The main function is to maintain the vertical state of the cable. It is also a mooring point for transport ships between the ground and the moon.
Concept map
The interior of the elevator car is relatively simple, the passenger area and the material area are in the same space, the other end is the operation area, and the cabin door is in the middle
Diagram of the interior structure of the car
Well, the above is the information of the space elevator brought to you by half a cat, for more details, you have to go to the cinema to see it yourself.
