Because the mass of the Earth is much larger than that of the Moon, the Lagrange point is only less than 70,000 kilometers from the Moon, but it is more than 300,000 kilometers away from the region.

This is basically equivalent to building a space factory in the outer space of the moon, but fortunately, not to mention the outer space of the moon now, millions of people live and work on the moon, and there are many flights between the earth and the moon every day, and the travel is still extremely convenient.

Galaxy Technology Group's spacecraft is like a straight line in the void, and in space, it also uses the power technology of rocket thrust to accelerate.

One by one, they dragged a long tail flame and headed in the direction of the moon at a speed of tens of kilometers per second.

In the dark starry sky, such a large number of anti-gravity spaceships moved at the same time, forming an extremely beautiful landscape, looking at it from a distance, it looked like a huge swarm of fireflies, and it seemed to be a huge space fleet from the depths of the galaxy, and the momentum was immense.

After a full 3-hour voyage, the team led by Wu Renjie arrived at the predetermined location, and all the anti-gravity spacecraft landed directly on the moon first, and then took off from the moon and flew back to the predetermined Lagrange point.

There is no way, the speed of the spacecraft is too fast, and it takes too long to slow down in space, so it is better to fly directly to the moon, rely on the strong gravitational pull of the moon, and then use the anti-gravity engine to slow down more quickly and safely.

Taking off from the moon again, the speed of the spacecraft is very slow, and the distance of less than 70,000 kilometers is simply an insignificant distance for a spacecraft.

"Lagrange point confirmed, you can start working~"

Wu Renjie's side, scientists from the Institute of Cosmonomy of the Galaxy Academy of Science and Technology used many positioning satellites distributed between the earth and the moon, and then used computers to easily and accurately calculate the location.

"Let's get started~"

Soon, an order came from the Earth Control Center, and the Ground Control Command Center had apparently calculated that they had arrived at the predetermined location and ordered the construction of the space factory to begin.

"Action~"

Wu Renjie nodded and gave the order.

As his order was issued, more than 300 anti-gravity spaceships began to approach each other according to their respective numbers, some with more than a dozen spacecraft leaning together, and some with two or three spacecraft leaning together.

The ships approached each other, and the hatches slowly opened, revealing huge bellies, filled with large and small space factory parts, as well as astronauts in spacesuits and busy with astronauts.

On the spaceships, long mechanical arms began to stretch out continuously, and these high-tech mechanical arms from the ink claw mechanical technology are the most powerful tools for astronauts in space.

The direct distance of the spacecraft is getting closer and closer, and the mechanical arms on the spaceship begin to connect with each other, and soon, through these mechanical arms, these spaceships adjacent to each other are fixed together.

More robotic arms continue to stretch out, and inside the huge belly of the spaceship, there are also robotic arms, pulleys, etc., which begin to carry out the space factory parts inside.

Wu Renjie's spaceship No. 001 is here, Wu Renjie, who is wearing a spacesuit, has a rope tied to his body, and the whole person grabs a mechanical arm and slowly enters space.

"Package No. 1~"

Soon, when Wu Renjie came to the middle point of several spaceships, he didn't waste time, there is a supporting virtual machine in the spacesuit, which can clearly transmit the information of the accessories, sequence, spaceship and so on that need to be assembled, all they need to do is to follow the procedures set by scientists and engineers.

Soon, on top of the anti-gravity spaceship numbered 002 next to it, a mechanical arm slowly pulled out a component the size of a house.

This component is the core of the future of the space factory, similar to a heart-like existence, a cube-like existence, about the same length, width and height, more than ten meters long, each with a carefully set connection.

Just such a core component, its manufacturing, Galaxy Technology Group spent hundreds of billions of dollars, and the price of the materials used in it is more than gold, because although there is no gravity in space, it must bear the huge mass of the entire space factory.

But because the space factory is made of countless parts, there will be some other forces between each other, such as torsional force and so on, as the core, these forces may eventually act, it must be strong enough.

The core components were slowly transported by numerous robotic arms to the center of the spaceships, which is also the most stable Lagrangian point between the Earth and the Moon.

"The direction is wrong, the first face must be in the direction of the earth."

In Wu Renjie's mind, using the powerful virtual machine technology, the information monitored by various monitoring instruments around him will be transmitted, and at the same time, everything corresponding to the simulation and assembly in the quantum computer, anything that is wrong needs to be adjusted.

Because no matter how small the mistake is, if it continues to accumulate, it will eventually be fatal.

This is also why in the previous aerospace engineering, the reliability rate of all parts and components has reached 99.999%, and some have even reached several decimal places.

However, scientists and engineers are very nervous about each space mission, because a rocket, a satellite, it has too many parts, even if the reliability of each part is very, very high.

But as long as there is a little flaw or error, many parts and so on add up to extremely terrible, an accident will be a big thing, and the loss is extremely heavy.

Even if it was Uncle Sam in the past, in the use of the space shuttle, after several major accidents in succession, he had to give up the use of the space shuttle, and the consequences were so serious that even Uncle Sam couldn't bear it.

The core components slowly began to adjust with the help of the robotic arm, and soon they were adjusted into place.

With an anti-gravity spaceship, it's much safer in space, and with the combination of robotic arms and mindset technology, work in space is also much easier.

"No. 2, 3 Components~"

Wu Renjie soon gave the order again.

Soon, from the surrounding spaceship, new components were pulled out by the mechanical arm, but fortunately, the anti-gravity spaceship was large enough and the space inside was large enough, so every component was the size of a small building, and the fine small parts, small parts, etc., had already been installed when they were on the ground.

If it were just rockets to and from space, as it was a few years ago, let alone a space factory, a small International Space Station would need many of the most powerful countries on Earth to operate together.

This is the gap between the times and the gap in technology.

Without anti-gravity spacecraft, the interstellar space age would simply not have been possible.

Component 2 and Component 3 were slowly moved to the vicinity of Component 1, and then docked perfectly with the interface of the setting number under the control of the robotic arm, like building blocks.

The design of each component is rigorously calculated, and the accuracy requirements are also very high.

The entire space has become very busy, and the spaceships have gathered together to form a formation point, and each formation point has someone like Wu Renjie who is directing the formation.

The work that can be done with the robotic arm is all done with the mind to control the robotic arm, but there are still many places where the astronauts have to play in person.

The work is going very well, but not very fast, because in the sky, everything except the spaceship has to be careful and cautious, the slower the better.

Huangping Town, Galaxy Aerospace Industry Base, Ground Control Command Center here.

Qin Yi looked at the huge monitor with his eyes, and the screen on the monitor was transmitting the pictures of the front line back in real time, divided into many small screens.

Each small picture is an assembly point, very busy, and the mechanical arms are working tirelessly.

In the void of the Lagrange point, huge parts were assembled, some of which looked like huge tall buildings, even larger than the gravity-defying spaceship on the side.

But it's just a small part in a futuristic space factory, a large part assembled from many small parts.

"Spaceship No. 2 flies away~"

At this time, Wu Renjie had already entered the core assembly that had been assembled, and the entire core assembly also began to work, and mechanical arms stretched out from the core assembly.

At the same time, among the core components, compressed air began to be released, so that Wu Renjie and the others could rest assured that they could take off their heavy and clumsy spacesuits and float around in the core organization, directing the formation of the entire space factory.

As he gave the order, the mechanical arms that were fixed to each other began to loosen, and the anti-gravity spacecraft No. 2 began to slowly leave, and the hatch also slowly closed, and began to return in the direction of Earth.

This time, its mission has been accomplished, but the entire vast space factory project has only just begun, and it still needs to be returned to Earth and transported more formations.

"Spaceship No. 3 flies away~"

When the No. 2 spaceship left, Wu Renjie's side also ordered the No. 3 spacecraft to leave, and after the No. 2 and No. 3 spaceships left, leaving an open area.

And in the direction of this area, another huge component that has been formed is under the traction of the mechanical arm, and it begins to slowly float towards the core assembly, and the next thing to do is the combination of large components.
