Lunar elevator: reality or fantasy? Recently people exorcized

about the space elevator again. In this field not one spear is broken, not one scientific work and not one scientifically - fantastic work is written. And here again in the Network the message that the elevator can be constructed soon appeared. However, not Terrestrial, but Lunar. On the Moon and the attraction is less, than on Earth, and length of a cable should not be such huge.

And there is a wish to tell, how in the famous animated film “Three Bananas“:

Three hoofs, two horseshoes,

This elevator will go again.

the Satellite and a sled,

This elevator from the fairy tale.

Three screw-drivers, two butterdishes,

I of the boy, and the little girl,

If know the word - greasing,

Are included directly in the fairy tale.

Experiments of LiftPort Group

For those who did not read anything about space elevator in brief I will describe his idea offered still by Tsiolkovsky. To construct the elevator, three segments - the geostationary satellite located in an orbit almost in forty thousand kilometers from Earth, the station constructed on a surface or in mountains (it seems, say that the higher, the better - at the big height of atmospheric indignations it is less), and the cable connecting the satellite and station are necessary. The cable of such length from modern materials will not sustain a tension and will tear, or will attract the weight the satellite to Earth. So now to make the space elevator there is no opportunity.

And now we will talk about Lunar elevator . In 2003 Michael Leyn founded the LiftPort Group company. She began to be engaged in development of the general concept of the space elevator. Though I do not think that they could think up something new, all is thought up for a long time, at most - to make more exact calculations. However, likely, it is one of the few companies (frankly speaking, I did not hear about other, similar LiftPort Group), which stepped further calculations. The matchless experiments made by this company say that such elevator is possible, but still just there is no material for a cable which will sustain huge loading.

Experiments of LiftPort Group are as follows: climbed the special cable fixed on balloons which length makes 460 meters robots (naturally, to launch the elevator with people were afraid). But all - further these experiments business did not go. In 2007 the company was covered by financial difficulties, works on the elevator stopped. Despite disorders, LiftPort Group survived and continued to work. But they began to work not on the Terrestrial elevator any more, and over Lunar which was counted as more practical project.

According to developers, the Lunar elevator is much cheaper Terrestrial as the Moon has smaller inclination and the satellite which will hang over one point, will be in lower orbit, than geostationary. He will allow to save considerable means on delivery of spacecrafts to the Moon, and it is possible and to construct lunar scientific bases - material it will only be necessary to take into the Lunar orbit, and further - the elevator.

And developers assure that now the material suitable for production of a cable, already exists - it is synthetic Zaylon fiber (Zylon).

, It seems, everything is clear - calculations are, the superthread is, but all - something is missing. Michael Leyn told: “I said earlier that in the project of the space elevator we so far not that - all questions we do not know all answers. For the Lunar elevator it is even more fair“ .

We need only to repeat:

Three hoofs, two horseshoes,

This elevator will go again.

the Satellite and a sled,

This elevator from the fairy tale.

Three screw-drivers, two butterdishes,

I of the boy, and the little girl,

If know the word - greasing,

Are included directly in the fairy tale.

Perhaps, after these words the elevator will start.
