Japan is ready to experience the world's first "space elevator"

The site Phys.orgdedicated to fresh science and technology news, it was reported that scientists from Japan are planning to test the "space elevator", thus becoming the pioneers in this area.

In the near future, a mini-prototype of such a "space elevator", whose length is 6 cm, width and height - 3 cm, will deliver an H-IIB rocket into orbit.

The H-IIB rocket of the Japanese space agency JAXA is a single-class middle-class carrier rocket. It can be used to launch an automatic H-II Transfer Vehicle to the orbital station, and also to transfer the payload to a geostationary or reference orbit.

The movement of the “space elevator” will be provided by the cable stretched between two satellites and controlled by cameras installed on the devices.

Successful testing of such an "elevator" will allow in the future to carry out cargo deliveries into space without the aid of rockets.

Japan is not going to stop there. So, the construction company Obayashi is already engaged in the development of a “space elevator”, which by 2050 will deliver tourists into space.

The company said that to create a cable with a length of 96 thousand kilometers, carbon nanotubes, which are more durable than steel, may be used. How these cables in the future can affect aviation movement, the company does not say.

Well, at least someone was puzzled by orbital elevators - the first serious step in the space expansion of mankind. Well, a hen of a grain ...

Good deal.

This idea was proposed back in 1959. Space tower of Pokrovsky magazine "Tekhnika Molodezhi" April 1959

[electrooleg]

Let them not even dream. Japan is a microscopic bug in the world of the space industry.

[Shurik70]

The first idea of ​​a space elevator was expressed by Tsiolkovsky in 1895.
He proposed to build a tower. He calculated the required loads and concluded that with the then materials it was impossible to build such a tower.
Pokrovsky in 1959 (the same "Technology of Youth" for April 1959) invented how the Tsiolkovsky tower can be built from the materials then available.

As for the practice of an elevator on ropes, people forget about the millions of debris and other space debris that humankind has spoiled in orbit. What will happen with a cable stretched with a force of many tons, when any tiny fragment touches it at space speed, there is no need to explain.
The elevator will work at best for several days.

Not the USSR, but Stanislav Lem, if I am not mistaken .. "Fountains of Paradise"

[Alexey RA]

Quote: 210ox

Not the USSR, but Stanislav Lem, if I am not mistaken .. "Fountains of Paradise"

The author of "Fountains of Paradise" is not Lem, but Arthur Clarke.
Clark himself in the preface wrote that:

The novel “Fountains, Paradise” is interesting in that it is the first (I hope) book, which is based on the invention of a Soviet engineer - the project of “space elevator”. Although the Western world first learned about this daring idea from the work of several of our oceanographers, published in the journal Science on February 11, 1966 (we now have extensive literature on this subject), it later turned out that this idea had already been developed six years earlier - on a much grander scale - by the Leningrad engineer Yu. N. Artsutanov (Komsomolskaya Pravda, 1960, July 31). It is simply amazing that this bold idea was not widely known. The first mention of her, which I saw, can be found in the album of paintings by Alexei Leonov and Sokolov “Wait for us, stars” (Moscow, “Young Guard”, 1967). One color reproduction depicts a “space elevator” in action. The signature reads: “... the satellite, as it were, would hang motionless overhead, always at one point in the sky. If you lower the cable from the satellite to the Earth’s surface, then the cable car between the Earth and the sky is ready. It is possible to build a cargo-passenger elevator "Earth - satellite - Earth". He will move without the help of rocket engines. " Although General Leonov presented me with a copy of his book at the Vienna conference "Peaceful Uses of Space" in 1968, I simply did not pay attention to this idea, although the elevator in the picture rises directly above Sri Lanka! Obviously, I decided that cosmonaut Leonov painted this picture simply by joking.

[Mr Credo]

The idea of ​​a space elevator has long been voiced by science fiction writers. The whole problem was in the technical support of the project. Suppose a wire with a cross section of 1 mm and a length of 96 thousand km will have such a mass that it can not withstand itself, not to mention the load. Let's see how this idea will be implemented.

[Fedor egoist]

Quote: Mister Creed

Suppose a wire with a cross section of 1 mm and a length of 96 thousand km will have such a mass that it can not withstand itself, not to mention the load.

So yes, I agree. But do not forget that with increasing height, the weight decreases, plus the centrifugal force. So it makes sense to build an elevator near the equator and possibly with a "transfer station" (a stratospheric platform on balloons) at an altitude of 20-25 km.
UPD: 96 thousand km - fierce Japanese delirium. 300-500 km is enough.

[Wedmak]

UPD: 96 thousand km - fierce Japanese delirium. 300-500 km is enough.

This is not completely nonsense, it is space mechanics. At 500 km orbit, the body moves much faster than the rotation of the Earth. And only on 35 786 km do their speeds coincide.
What does garbage do on 96 thousands, I also did not understand.

[Fedor egoist]

Quote: Wedmak

At 500 km orbit, the body moves much faster than the rotation of the Earth

+
Already googled, absorbed information on the issue :) Indeed, at an altitude of 300-500 km you cannot hang a geostationary platform) Most likely, as a result, there will be an elevator from several sections moving at different speeds at different heights. And the system of "picking up the load" from intermediate platforms. Outside the atmosphere, this is quite realizable.

[Razvedka_Boem]

Arthur Clark painted everything well .. Read, it's more interesting than Google ..)

[Wedmak]

Most likely, in the end there will be an elevator of several sections moving at different speeds at different heights.

I'm afraid it won't work either. Speeds too high. And you just need incredible accuracy. So far we have not grown to such projects, the complexity is beyond the limits at the moment.

[tatarin_ru]

35 km only

all the same, probably in meters, but not in km? 35 786 meters

[Wedmak]

No, I was not mistaken, ~ 35 thousand km. Your 35 786 meters are still within the atmosphere.

[Antares]

Quote: Wedmak

What does garbage do on 96 thousands, I also did not understand.

maybe the entire length of the cable, then it will be 48 thousand. Anyway, a lot ..
However, there are projects on 35 96 and 160 thousand.

[S-kerrigan]

96k - this is also not nonsense, just the same cosmic mechanics .... the counterweight is called.
They want to hang the "main platform" at 36k, and then they need an additional tensioner.

[Wedmak]

and then you need an additional tensioner.

And still my not to understand. This tensioner will move much slower than the platform. For cosmechanics - the larger the radius of the orbit, the slower the body moves. If you disperse it, it will fly nafig out of the system, no cables will keep it.
IMHO, one cable and one platform is also not an option. The final option is a ring around the Earth with a hundred or two elevators to the equator. True, this megaconstruction is a matter of a very distant future.

[demo]

The speed is not linear, but angular.
Sit in a carousel, on chains, take a stick in your hand and go.
The angular velocity of the shoulder is x, the brush, y, and the end of the stick is z.
And the linear speed of the end fixed on the ground is 0.
And the speed of a km hanging on 96000 is equal to the angular speed of rotation around its axis.
Probably so.
In the case of such a construction (I doubt it), the main question is what can be delivered there.
10000 kg of additional payload per cable - this seems to be not much.
Just a cable should be designed to be many times higher than the most durable metals and materials.
People need a break.
And look around.
Nature - mother can tell a lot.
For example a spider web.
This is where the peak of creation is.
The loads that it withstands, with that thickness and those materials, are fantastic.
And the flights of spiders using their own web and suitable weather conditions?
And the wings of a lumberjack-relict providing its owner with local antigravity, reducing the energy costs of the body.
Thousands of examples are in front of my eyes.
Truly! "Those who have eyes, let them not hear! Those who have ears, let them not see!"
I’ll add from myself - those who have a brain, but they can’t think.
And I advise you - look and find out.

[yehat]

can you find out the name of titanium, on the shoulders of which a satellite is held in a geostationary orbit? simply
it is worth considering that part of the cable will be close in behavior to this satellite

[Pontiffsulyvahn]

Carbon structures will withstand. The problem is different - to achieve uniform quality of each link. If at least one is defective, the cable will break - and the lower this defective link, the more likely it is.

[SOF]

Quote: PontiffSulyvahn

the cable will break

... it's even scary to imagine what kind of destruction on the ground will be produced by the fallen end of the broken "cable" ...

there is a Japanese series Gundam 00 Season 2, where a drop of such a cable is drawn

[Vadim237]

On a computer program simulate.

[Pontiffsulyvahn]

Modeling is not a problem - the problem is to produce millions of links without flaws.

[Vadim237]

3D printers for metal and graphene to help them.

[Pontiffsulyvahn]

Yeah, nevertheless sofa designers are something ... maybe you’ll call a model?

[Vadim237]

Unlike some, I am a process engineer, a real designer. And about 3D printers for graphene until the year 2050, this will definitely appear, for metal they work fine now.

Spacecraft using solar sail.
Soviet scientists invented a scheme of radiation-gravitational stabilization of a spacecraft based on the use of a solar sail. The first deployment of a solar sail in space was carried out on the Russian spacecraft Progress M-15 on February 24, 1993, as part of the Znamya-2 project.
The first to use space sail as an engine was Japanese IKAROS, which is considered the first space sailing ship in history. On May 21, 2010, the Japan Space Agency (JAXA) launched the H-IIA launch vehicle, on board which were the IKAROS spacecraft with a solar sail and a meteorological device to study the atmosphere of Venus. IKAROS is equipped with a sail made of the thinnest membrane measuring 14 x 14 meters in length and width. With its help, it is supposed to study the features of the movement of vehicles with the help of sunlight. $ 16 million was spent on the creation of the apparatus. The deployment of the solar sail began on June 3, 2010, and was successfully completed on June 10. From the footage transmitted from IKAROS, we can conclude that all 196 square meters of ultra-thin canvas have been straightened successfully, and thin-film solar panels have begun to generate energy. " / wikipedia /.

Japanese test results IKAROS on wikipedia not.

Expansions where sorry ...
Even if an elevator is built tomorrow, you and I are in a perfect planet earth prison, leaned above the Van Allen belt and all die. We need to learn to fly through outer space at speeds higher than those we can now, an elevator here will not help us.

[sabakina]

The movement of the “space elevator” will be provided due to the cable stretched between the two satellites

Bullshit. Didn’t they hear about Archimedes? "Give me a foothold and I will turn the Earth." How will the satellites in space hold the cable tension?

[Sadko88]

You can tie to the moon

[sabakina]

Suppose, what about the rotation of the moon around the earth?

[Logall]

Slavik, there is still garbage in the fact that this cable cannot be lifted from the ground - it is heavy! Will they weave it in space? With the help of a draw?

Centripetal force sir. Japanese are not so stupid as you think.
Archimedes was right and the Japanese did not protizh. The foot support in this case is the grip of the cable to the ground.
Imagine that you tied a pebble to the end of a rope, twist it.


if by some miracle they can pull the cable with a weight, then things will go
but it seems to me that we will see such an elevator in 100-200 years at best

[sabakina]

If the Japanese aren't stupid, why aren't aliens using this technology? Yes, they pump out energy from the Sun, but obviously not with the help of the Made in Yapan cable.

[gurta]

Quote: Maki Avellievich

And what, and indeed, tied, pulled, thrown. Now, let's calculate the influence of wind and residual oncoming and outgoing waves on this "rope". It seems to me that the flapping of the wings of a butterfly (the bird has sat down) in this case, due to the fact that the rope is not rigid, will end with a huge oscillation of the station. What rockets should be installed at the station to extinguish this pendulum? or a vibration damper to the station, but how to anchor it? There are more questions than answers.

[yehat]

I am more interested in another question - let's say they will build a stable elevator, but moving goods with support on it completely breaks the fragile balance.
I'm not talking about the huge leverage that will create the load.
It seems to me that the key to success is combining Archimedes' law with another technology of displacement in a discharged stratosphere.

[Andrey Panov]

If they can put such a stone into orbit, why do they need an elevator? By the way, no one tried to calculate the weight of a pebble?

The weight of the kettlebell is not necessarily huge. the calculation takes the cable dkinna, the speed of the earth's rotation and the absolute speed of the counterweight.
In addition, the ISS also weighs quite a lot. picked up slowly and collected

No, the pebbles on the rocket will be raised with a rope, and then slowly lowered to the ground for how much rope is enough. And there will be movement of two connected bodies in space.

[sabakina]

The company said that to create a cable length of 96 thousand kilometers,

One out of two. Either everything in this company is malacholny, or a little one has crept in.

So, the construction company Obayashi is already engaged in the development of a “space elevator”, which by 2050 will deliver tourists to space.

Che-that it seems to me that in the 70s, Technique - Youth published Artie Clark's novel "Fountains of Paradise" about the space elevator

So in "TM" first published the novel by Clark. And then, just in No. 4 for 1977 - a scientific and technical analysis of one of the concepts of the novel.
Here is what Clark wrote about it:

Reading the proofs of this novel, I received from Dr. Jerome Pearson a copy of the NASA TM-75174 Technical Memorandum with a translation of G. Polyakov’s article “The Space“ Necklace of the Earth ”published in 4 by Technics - Youth magazine No. 1977.
In this short but informative work, Dr. Polyakov (Astrakhan Pedagogical Institute) describes in precise technical details the vision of the hero of my novel Morgan about a closed ring around the globe. He sees it as a natural continuation of the “space elevator”, the construction and operation of which he interprets in the same way as I do. I salute Comrade Polyakov, and again the thought comes to me that I was too conservative. It is possible that the Orbital Tower will be the achievement of the XNUMXst, and not the XNUMXst century.
Perhaps our grandchildren will be able to prove that sometimes the colossal is beautiful.

[sogdy]

NASA began with stratospheric exploration. In 1949-1956, figures were obtained to estimate the load. (If anyone is interested, they almost got to an altitude of 29 km. On "balloons." Test runs up to 45 km.) In fact, a system like a mechanical lift completely loses its meaning even for Mars.
By the way, a flash of interest in superconductivity was also caused by a similar system.

[Doliva63]

Enlightened, thanks!

[Kerensky]

There is a collection of funny problems: "Look at the root", Makovetsky. There a similar situation was considered. The curious can get acquainted.

[Alexey RA]

Giggles ... EMNIP, this book looked at the situation from the point of view "after what time will such a design bring down all the satellites whose orbit falls below its upper point".

[Wedmak]

The cable seems to have been abandoned - too unreliable. It was proposed to make sections in structure reminiscent of the Shukhov tower, several hundred meters each. And inside, already, on suspensions, to start up two "roads", one elevator car rises, the other goes down. And there can be many such cabins. I don’t remember about the speed, it seemed like the climb took about 2 weeks.

[midshipman]

I remembered my youth At the University of Leningrad in 1963 at the Physics Department they considered such a model. Then we were still studying the new meaning of Newton's law "The force of action is equal to the force of reaction, but they are not manifested simultaneously."

Vashcheta, the task was - the traffic of goods to the station under construction. From there comes the phrase about two satellites connected by a cable. No one is going to lift loads from the ground. But commercial carriers do not take goods into orbit strictly in order.

[Good fellow]

There was a mention of a similar elevator design by writer Charles Sheffield in his science fiction novel Heritage Universe.
True, the elevator connected as many as two planets: the ancient "builders" (a race a billion years older than mankind arranged experiments being at the peak of their technical capabilities) tied two planets with the "umbilical cord" Platforms went around the umbilical cord. Also, space archaeologists mention a builder's artifact, which completely braided the whole planet with pipes several kilometers in diameter, with the help of which certain cargoes were apparently brought into different orbits of the planet.

But if the "ant" is kicked without a rope, the perfect work (physical concept) will be much less.
Again, how are you going to apply the same circular impulse to bodies on earth, which is applied - in proportion to mass - to the ant? Otherwise, it won’t go.

[Vladimir Postnikov]

You did not realize the question, as did the overwhelming majority of comments written here.
The question was rather rhetorical:

due to what forces will the payload be put into orbit

The question is for people who are aware of the basic laws of mechanics. They do not know, but do not realize (!).
For example, you fantasize with your example. Your ant will not crawl anywhere, especially in the direction from the center of rotation. It will fly away rather quickly, and in a tangential direction (in plan) relative to the center of rotation.
You better take a pencil with a piece of paper, and calculate what the so-called centrifugal force acting on the body at a distance of 1000 km from the Earth’s surface as a percentage of the weight of this body (gravitational force acting on this body) will be, provided that it was possible to build this elevator.
And yet, regarding your example, in nature there is a difference in movements along and across the action of the gravitational force.

due to what forces will the payload be put into orbit

The "Tros" holds the platform in geostationary orbit vnatyag due to orbital mechanics. Just because it can. What forces act on this cable, we will not discuss, it is clear that there is a lot of it. And the elevator itself climbs there stupidly clinging to the cable and crawling along it. Something like that in theory. But in practice ... questions and problems a wagon and a small cart.

[abc_alex]

About 96 thousand kilometers is a clear typo. Look at the diagram. We are talking about 96 thousand meters. That is, they will be launched into 100 km orbit.

[zulusuluz]

Quote: sabakina

How will the satellites in space hold the cable tension?

Centrifugal force. Beyond the geostationary orbit, a body "hanging" over a point on the earth's surface will experience a centripetal force, and this rope will hold this body.
I’m not talking about the technical side, but as an example, the moon in orbit rotates at a constant speed. In order to move it from orbit, it is necessary to accelerate it - it will begin to move away from the Earth, or slow down - to fall to the Earth.

[sogdy]

Quote: zulusuluz

will experience centripetal force, and this cable will hold this body.

Hmm. Such a smart word is "precession".
The precession of the moon (non-geostationary) reaches 10% in all dimensions. The requirements for current geostations are even lower.

this is not an elevator. This is comparable to a matchbox.

I also did not understand the size of something))

Wow "news" ... In the US, news is regularly published on this topic, with a description of the materials and even estimates ..

The company stated that carbon nanotubes, which are more durable than steel, may be used to create a cable with a length of 96 thousand kilometers. How these cables in the future may affect the air traffic, the company does not say.

Not possible, but for sure, modern materials will not stand their own mass.
The specified length of 96 thousand kilometers is quite high. Although for 160 thousand you can abandon the counterweight (the mass will be the counterweight itself)
Common projects in 35 thousand.
The load on the cable may exceed 100 kg / m, so that the material for its manufacture must have extremely high strength for tensile strength, and at the same time very low density. While there is no such material, even carbon nanotubes, which are now considered the most durable and elastic materials on the planet, are not suitable.
Unfortunately, the technology for their preparation is only just beginning to be developed. So far, it has been possible to obtain tiny pieces of material: the longest nanotube that we managed to create is a couple of centimeters in length and several nanometers in width. Whether it will ever be possible to make a sufficiently long cable out of it is still unknown.
On the moon, it’s easier to create this system.

If you make this cable from titanium with a diameter of 30 mm and a length of 200 kilometers, its mass will be 638 tons, with 20000 kilometers - 63800 tons. With a tensile strength of 1600 MPa per millimeter squared, the cable will be guaranteed to be torn apart with a force of 3000 tons - tensile.

The ISS flies at an altitude of 350-400 km from the surface of the earth. Based on these calculations, it is quite possible to make a titanium cable of such a length and even lift loads on it. But this has not yet been done. Do you know why?

[Vadim237]

Because the cost of such a cable will amount to more than a trillion rubles, there is no such rocket with a carrying capacity of 638 tons and the ISS itself does not hang in one place.

But they will make such a cable .. Why did the commentators take it to be titanium? .. If they don’t know something, this does not mean that science stood still ..
In the Internet, nothing disappears and figs that you guard ..)
It will be funny to read all these objections in a couple of decades ..)
