It can be said that with the sincerity of the Brazilian government and the strong support of Tang, the city of Macapa has finally become the preferred location for the "space elevator" on the earth, as long as the Brazilian government does not make this place the same as the 2016 Olympic Games, it is estimated that no one will raise objections......

The "space elevator" has two terminals, and now that the earth end has been determined, then the space end still needs to be determined. Pen "Fun" Pavilion www.biquge.info

To put it bluntly, the space side of the "space elevator" is a spacecraft that is large enough, and this spacecraft must be able to automatically change orbits, and it must also have enough power to resist the "gravity" caused by the initial stage of the "space elevator" and the earth's gravity.

Because if you want to build a "space elevator", it can't be completed all at once, and the construction of this big guy will be carried out in stages. The first stage is to bring a "cable belt" with a total weight of about 40 tons to a spacecraft in low-earth orbit about 400 kilometers from the earth, and this cable belt is not the final kind of cable belt that is 1 meter wide and 2 microns thick, but a small cable belt with a width of only a few millimeters.

This small cable is secured from this spacecraft and then released towards Earth. After the Earth's side receives the small cable and fixes it, the second stage of the "space elevator" can be started, that is, from 400 kilometers of low-earth orbit to 36,000 kilometers of geostationary orbit. When all the small cable belts are laid, the special small elevator is used to widen the cable belt, and finally the cable belt system of the entire elevator is formed.

In fact, the most difficult part of building a "space elevator" was in the first stage.

A small 40-ton cable is nothing in space, but if you want to lower it to the surface, it will be a very difficult project. The most important thing is that the spacecraft as a platform must have enough power to withstand the gravity brought by the downward release of the cable when the small cable is released downward.

If the spacecraft does not have enough upward momentum, then simply releasing the gravity brought by this small cable will directly "drag" the spacecraft from space to Earth......

At present, there are only two large-scale spacecraft that can be used as this platform, one is the aging International Space Station, and the other is the newly released manned Mars spacecraft -- Prince Barnett.

Although the International Space Station can barely reach the role of a platform in terms of volume and area, this old guy is too old, and the most important thing is that this old guy's power is obviously insufficient, and now it is able to maintain the ability to change orbits in a small area. If you want the ISS to take on the first stage of the platform, it will definitely not work, because the ISS without enough power will be 100% dragged down by the force when the small cable is released.

As a result, only the "Prince Barnett" is currently eligible for human beings.

The "Prince Barnett" is large enough to act as a space terminal for the "space elevator", and even if there are some areas that need to be improved, it is only a matter of a few launches of the "Starfield" heavy launch vehicle. The most important thing is that the "Prince Barnett" has enough power to support the first phase of construction.

The three main ion thrusters of the Prince Barnett itself are not strong enough, but don't forget that the Prince Barnett also has an acceleration rocket engine for acceleration, which is a rocket engine that uses chemical fuels and has enough thrust. Not to mention that the "Prince Barnett" also has two landing ships with more powerful thrust, the "Eagle Falcon" and the "Kunpeng".

In fact, the power system on the "Eagle Falcon" and "Kunpeng" is enough to support the release of small cable belts, and these two landing ships have perfectly proved their own powerful thrust. The hull of a ship weighing tens of tons can successfully rise from Mars, and its thrust can be as high as several hundred tons, which is more than enough to cope with the first stage of small cable release.

It would take at least two years to build a spacecraft with similar functions as the Prince Barnett, even if it were a global effort. Therefore, if you want to make the "space elevator" project really enter the regular as soon as possible, it is best to take the "Prince Barnett" directly and use it.

It's just that the "Prince Barnett" is Tang's real private property, and now there are still three months before the "Prince Barnett" returns to Earth, and everything depends on Tang's meaning.

This is a Martian spacecraft worth more than $80 billion, whether Tang Feng is willing to come and talk about it is another matter.

However, Tang Feng was not so stingy, and after learning the exact news, he directly decided to let the "Prince Barnett" out and act as the space terminal of the "space elevator".

Tang Feng's atmosphere has naturally won the support of almost everyone. It is estimated that now on this planet, only Tang Feng can do such an atmospheric thing. The $80 billion was directly contributed without blinking......

Of course, Tang Feng's atmospheric move has also won the support of more people. Under the deliberate propaganda of some well-intentioned people, Tang Feng's image has become even higher, and it has also let more earthlings know that only under the leadership of Tang Feng can human beings truly go to the depths of the universe and completely implement the Martian immigration plan.

It's just that there are still three months before the "Prince Barnett" returns to Earth, and the construction of the "space elevator" is urgent, and it will not start until the big guy returns to Earth.

However, Tang Feng has not been idle in the past three months, although there is no big deal for Tang Feng now, Tang Feng still decided to prepare in advance, for example, to ask Eric for some high-tech that the earth has now touched the doorway, but it cannot be implemented on a large scale.

Like controlled nuclear fusion technology, like ultra-large ion thruster technology, like magnetic field engine technology, like carbon nanotube technology, like some special material synthesis technology......

These technologies have been realized in some high-end laboratories on the earth, and it can be said that these technologies have actually been mastered by human beings, but they are still far from large-scale application, which requires the accumulation of all aspects.

But Tang Feng didn't want to wait so long, and similarly, Eric didn't want to wait so long. Tang Feng wants to transform Mars into a planet suitable for human habitation as soon as possible, so that humans can have a second home. And Eric is also anxiously waiting for the three star cores promised by Tang Feng, the new master, for this reason, Eric has even already chosen a rocky planet with intelligent life for Tang Feng, as long as Tang Feng has time, then the Doug family will naturally have three planetary star cores again, if you are lucky, maybe one of them can be promoted to a stellar star core......
