"Why do I have tears in my eyes, is it because I have been thinking about this day for too long?"

"I also feel a little sad when you say this, maybe it's like what Dong Chen said, we humans are finally going to officially go out of the earth."

"Well, at least after the completion of this new Tiangong space station, it will be much easier for us humans to move in space."

"That's right, this is much more professional than the International Space Station, it is definitely a standard spaceport, spacecraft docking, personnel rest, material supply, equipment maintenance is the same, if it is a little bigger, it is a fully functional space base."

"It's already very good, those functions are built on the head, and the tonnage of more than 5,000 tons is supported there, and it will definitely be stronger than the International Space Station."

"That's right, even if the United States has the technology to simulate gravity, the 400-ton small-tonnage space station can't be used at all, the main reason is that their launch cost is too high, and most of it is spent on freight, and it is really possible to vomit blood to build a space of thousands of tons, let alone more than 5,000 tons."

"That's right, so a 400-ton space station is the result of multinational cooperation, and the maintenance cost is also a lot, and now they are considering whether to continue to invest money here, and I instantly feel that the International Space Station is so pitiful."

"The transportation fee of Arc Aerospace is half of that of Musk's aerospace, but looking at the scale of their new Tiangong space station, their cost is absolutely low and terrible, otherwise they will have to go bankrupt before it is completed."

"It's a breakthrough anyway, and since you dare to build like this, you must be able to bear it."

"I think this big brother's welding skills are very good, and he may also be a very good welder on the earth."

"He is now the number one welder in space, and I think there is nothing wrong with this title."

"There's nothing wrong with it at all, it's impossible to send a second place in the mission in this case, it's definitely the most powerful person in space right now."

"I feel that we humans are so good that we can work anywhere, but in fact, human beings are still very adaptable."

"I feel proud to be human! This is how the starry sky is occupied by us little by little. ”

When Yang Nianming started the welding work, Dong Chen returned to the living module of the space station, and the remaining fourteen space workers also joined the construction one by one, and the robots with different roles also moved.

Since there is no place to store materials in space now, all the materials and parts are in the cargo hold of the aerospace transport plane, and they will only be taken out of the cargo hold when they are used, so if Dong Chen wants to return to the earth, he must wait for the first aerospace transport plane to unload the goods.

He didn't have a problem with that, and after having a relatively large space for activities, he was quite happy to stay in space for a while.

However, these people and machines are all moving very fast, and these goods are not simple steel plates, but parts that have been pre-shaped, some need to be welded, some need to be glued, and some even need to be assembled into one piece.

In fact, all the parts have been built on the ground, and some internal and external infrastructure exists, and when the time comes, they will be assembled or welded together, and then the instruments and equipment can be installed directly inside, and modularity is so convenient.

The process should be streamlined as much as possible, otherwise even robots working in space will waste a lot of time and energy.

After all, there are a large number of employees in the manufacturing base on the ground, as well as intelligent equipment for manufacturing, so it is not a matter to do this. As long as you don't reveal it, no one will ever know how productive you are.

After the "Eagle" and "Falcon" class aerospace aircraft have been produced, they have officially entered the stage of intelligent mass production, and only a small number of engineers and senior technicians will be needed to complete the production speed much faster than before, and soon you can see many aerospace transport aircraft shuttling back and forth.

After the space station's maintenance workshop and living quarters are formed, more construction personnel and robots can be dispatched to the space station to carry out construction tasks.

So don't look at the new Tiangong space station is the largest space construction project in the history of mankind, but its construction schedule will definitely be scary, and it will not even take a year to complete the entire construction.

The new space station will not dock with the current space station before it is built, because vibrations often occur during the construction of the space station, which is very unfavorable for some space experiments, and there will be noise to disturb the astronauts.

Although the vacuum cannot transmit sound, if it is docked, the solid conduction will transmit the sound to the space station, and there is air inside the space station, so it will make the space station very noisy.

In addition, the newly built space station will continue to move in small increments during the construction process, so the engine will often be started to adjust the orbit, which is also a bad thing that will affect the experiment.

Fortunately, the "space construction site" is not far from the existing space station, and if the workers want to come back to rest, they only need to fly a short distance, and the spacesuits under the control of the intelligent control system will definitely send them back safely.

Dong Chen sat in the living cabin and waited for the first plane to be unloaded, everyone else was busy with work, and the live broadcast perspective was also on the "space construction site".

Looking at the netizens' comments on his speech, Dong Chen also nodded and smiled with satisfaction, he just opened the taunting skill, which was deliberate.

I want to motivate them to catch up quickly, but also to see if anyone will jump out to find trouble.

According to the information he had, the "small unmanned space plane" experiment of the United States has been close to success, of course, it is actually a space shuttle, after all, it cannot take off directly from the ground, and still has to rely on rockets to send it up.

But it has done what its predecessor couldn't, which is a lot improvement in reliability and reusability, and a lot reduction in the maintenance procedures and maintenance costs that have to be carried out after the mission.

Although it looks small, unmanned, and has a payload of only two tons, it is still very slippery when it comes to experimental equipment or decorating missiles or something.

And now the launch vehicle technology of various countries has also been greatly improved, mainly stimulated by arc spaceflight, and the space appropriations of various countries have increased a lot, although the time is still very short, but there is an accumulation of the original, as long as it is ...... If you have money, you can do things.

Therefore, the rocket carrying capacity of various qualified countries is also increasing, especially those already powerful space powers, and they are basically trying to master reuse technology to reduce costs.

It is foreseeable that in a few years, it will be much easier for countries to send goods into space than before.

Due to the technical support of Arc Group, Huaguo is now one step ahead of them in terms of transportation, but other aspects still need to catch up.

The development of private companies is also rapid, stimulated by arc spaceflight

A few years passed quickly for the state or other companies, and they were confident in their plans.

It's just that a few years is really too long for the Arc Group, and for such a long time, the Arc Group may not necessarily go anywhere.

There is also Dong Chen noticed the hope for the future of mankind revealed in the words of some people, which is also what he wants to see.

Originally, all countries focused on the earth, but because the early accumulation of space technology was too expensive, many people were reluctant to develop in this area, and felt that they could not see the benefits, so only a limited number of companies and countries were developing.

Due to the low investment, the development is very slow, which makes the starry sky seem unattainable and unprofitable.

And Dong Chen's big move attracted people's attention to the starry sky again, and because of the arc technology, people saw the future in front of them.

And then there is the trifecta of qualities of the peoples of other countries: what about our aerospace aircraft? What about our big space station? What about our space workers?

The National Space Administration of those countries is also bitter, the state does not allocate funds, they have a gross use.

But they don't dare to say that, they just advertise that state institutions and private companies are incomparable, their functions are different, and they hope that the people will be rational.

The people don't care about this, the media said every day that a private aerospace company surpassed China's aerospace strength, and those people in China also scolded them every day.

No, scolding and scolding arc space came out.

We have to scold, and we have to scold every day!
