The Navigator has never disappointed, not in the past, not now, and not in the future.

A week later, the huge manufacturing center was lifted off.

The manufacturing center is not an empty shell maintenance pod, it is equipped with a lot of heavy equipment, which is used to complete the dismantling, crushing, refining, manufacturing and other processes, turning space junk into raw materials, and then turning raw materials into usable parts.

So it's not only huge, it's also huge, and its monomer mass has reached an unprecedented 260 tons!

This weight is close to the maximum near-earth payload carrying weight of the Yishan rocket, and it also proves from the side how big and heavy the manufacturing center is.

With a diameter of 15 meters and a length of 35 meters, it is more than two turns larger than the maintenance compartment.

And because the length of the cargo compartment of the Yishan rocket is only 40 meters, which also includes some top shrinkage parts, the side of the manufacturing center is also made of a shrinkage structure, so that its main body is a bit like a combination of a round platform and a cylinder.

It just so happens that the reduced side of the platform is used to dock with the commercial area, and there are two retractable berths on it, because they are on the side of the platform, they are inclined and will not be on the same plane as the maintenance module after deployment, which is conducive to the docking of spacecraft.

If the equipment brought back by Worker Bee 1 is too large for the two to coexist in the maintenance bay, Worker Bee 1 will dock at these two berths, and they can also dock manned spacecraft.

Don't forget, the coaxial gates of the research, business and industrial areas are usually closed, and the engineers and technicians of the industrial area enter through these two entrances.

What do the audience want to see?

Let's have a live broadcast.

Even Tang Chao was too, he had only seen it on Kanxing's side, it was a bunch of little green men wearing big mechas, circling around the equipment, and he really hadn't seen humans in space, wearing indoor spacesuits and repairing satellites in pressurized cabins.

This time, I'll have to take a good look.

But unlike those viewers who can only watch the live broadcast, he is going to the scene.

Not only is he going, but even the Tianxia official is coming.

After all, this satellite is Tianxia's communication satellite, this type of communication satellite uses a mature satellite platform, and the mature satellite platform will not be used for a few years and then abandoned, but will be used for more than ten years, or even decades, during which there must be upgrades and improvements.

Is that easy? Are all a basic platform? Then install the carrying equipment, so the so-called upgrade plan is to transfer the advanced satellite equipment installation plan of the same platform to this satellite in the later stage.

Even the equipment is ready-made, transported directly from the CNNA to Sweet Potato Island? And then into a manufacturing center? One piece can be transported up on the Yishan rocket.

There are four professional satellite engineers on the national team? Four professional engineers on the Navigator's side, plus two space pilots? These two are helpers.

A total of 10 people, taking the rail shuttle into the manufacturing center? It is planned to upgrade and maintain the satellite within a week.

This can be regarded as a challenge, originally the national team set a month on the side, but the Navigator Aerospace side analyzed and said that a week is enough.

This......

The four engineers of the national team are also old comrades, the youngest is close to 50 years old, and they also know that technology and society are constantly developing, but this development is also fast, right?

Then it's even more important to take a look.

Is the national team very serious about the first maintenance and upgrade mission? So he sent four of them.

The navigator is not so particular, they boldly sent newcomers? Have an engineer who builds satellites in a company? There are also those who have just been trained and have not built satellites? But then the space engineer who was going on a space mission.

And Tang Chao? This time, he is still the main pilot, and the co-pilot is an engineer professional trainee commander, and this time letting the other party come up is considered "training", and there will be many places to use him in the future.

By the way? Because of the addition of the illusion system, the astronaut training speed of the navigator has been greatly increased, and the tasks to be performed in the later stage must be more complex, so the traditional training process is not suitable.

Tang Chao had a meeting with the senior management, and several new environmental training subjects were added.

This includes "Space Wars" and "Space Marine" training!

Although there are no signs of this, ...... Be prepared.

And he doesn't really train astronauts as space marines, after all, they are not full-time fighters, and they can't be space marines in science fiction works, so the gameplay of space war training is relatively large, at most it is a hardcore game.

There are no hard tasks and performance requirements, and leisure and entertainment can be used after training.

However, Tang Chao did not limit this project to the company, but put it in the company's game options, as a hardcore space soldier and space war training game simulator open to the public.

The outside player base is much larger than the astronaut group of the Navigator company, and if you don't know who likes this one, then carefully study it, and finally study something.

It doesn't make much difference now, but when it comes to some kind of critical moment, it may surprise him big.

So this hardcore "game", free!

A group of people took the rail shuttle to dock to the manufacturing center, the combination of the manufacturing center and the maintenance cabin is large enough, but the solar array on the manufacturing center is larger, and it is golden, which looks quite energetic!

After that, they wore in-cabin spacesuits and helmets into the manufacturing center, and then turned to the maintenance module, where they saw Worker Bee 1 quietly parked inside, and the communication satellite fixed in front.

Worker Bee 1 is fixed in the maintenance module, and the communication satellite is fixed on Worker Bee 1, but there are other fixtures in the maintenance module, and there is no gravity here, so there is no need to consider the load-bearing capacity of the fixture, so any robotic arm can play a fixed role.

The cabin spacesuits they wear today are somewhat special, especially the shoes, which are special electromagnetic shoes, which can allow the wearer to walk smoothly on the metal "floor" after opening.

There is some delicate work to be done, and they can't be so floating.

When Tang Chao controlled a robotic arm to grab the satellite and put the satellite from the Worker Bee No. 1 to a distance of 5 centimeters from the "ground", everyone stepped on the floor and walked to the front.

"I didn't expect to see it in my lifetime."

An engineer of the national team said with emotion.

"Yes, Lao Yang, you took someone to assemble this satellite back then, hahahaha, more than ten years have passed in a flash, and we are already old."

"This should be the idea of the organization to send Lao Yang over this time, and we have here, and he is the only one who knows this satellite best."

While sighing, they were not idle, but first circled around the satellite and took a look.

Tang Chao was in the column, looked at it, touched a small hole on the satellite that was not on the design map, and said: "Although the official information says that it is only the fuel is exhausted, it is obviously abnormally damaged, this small hole looks like a micrometeorite crashed out, but it just happened to not hit the key equipment, so the impact is not big." ”

"Well, we have a record, this satellite did have anomalies at several points in time, and our analysis was also impacted, but from the data point of view, the impact is not big, the biggest problem is just a little bit off the orbit." Yang Gong said.
