Chapter 79

The machine in front of it is the legendary industrial master and the core of industry.

Mother machine is a kind of manufacturing machine and machine, which is usually used to make all kinds of high-precision machine tools. It is the most important thing to restart civilization.

However, this device is also in storage. Generally, it will not be opened.

The next one is a heavy metal 3D printer, which is also the only super large machine currently in operation. It can be used to produce some parts that are not particularly complex.

3D printing is a rapid prototyping technology, based on digital model files, using powder metal or ceramic and other adhesive materials to construct objects by layer printing.

In other words, after designing the equipment from the computer, it will automatically spit out various parts and assemble them.

"This classmate, can only see, can't touch, don't move. You can't afford to break it! "

One of the staff members saw Zhang Yuan looking around and issued a warning.

They don't like visitors like Zhang Yuan very much.

Flying around this place, if you really hit something,

although it's no big deal, the safety protection of the industrial zone has long been perfect. It's just that it's still annoying.

Elder martial brother Zhao said with a smile, "Lao Li, what are you doing? This is my younger martial brother. Pay more attention

"Hello, elder martial brother Li." Zhang Yuan quickly called out.

Every place in this production room is an important position with knowledge intensive, technology intensive and talent intensive. The minimum degree is also a doctor. It's nothing to call a senior brother.

Lao Li took a look at Zhang Yuan and said, "these are the top toys. If you want to study them, you can greet me as long as you don't sneak in and mess with them!"

"A few interns from foreign countries even sneaked into the warehouse and almost started the industrial machine, which blew me up."

Elder martial brother Zhao asked with a smile, "what happened later?"

Elder martial brother Li snored: "originally, he wanted to call the police to force them to hibernate. However, seeing that they were crying bitterly, he was soft hearted and let them go again..."

Elder martial brother Zhao looked back and joked: "Lao Li is a man with soft ears. If you pretend to be a little pitiful, shed painful tears and ask him to use a 3D printer to help you get a real machine out, it's not impossible..."

Zhang Yuan stared and pretended for a long time. He found that he couldn't pretend to be very pitiful.

It seems that he can't rely on his acting skills. From now on, he can only win by strength.

The whole factory on the first floor is almost finished. Under the spaceship, there are the second, third and fourth floors, which are mineral smelting and light industrial production factories. You can visit them later.

Zhang Yuan, too embarrassed to disturb others' work, pulls elder martial brother Zhao and leaves in a hurry

"What do you think after reading these?" Elder martial brother Zhao asked for the first time.

Zhang Yuan sighed, "it's great! These machines are the crystallization of the wisdom of countless people, even more important than our lives! "

"But it's very embarrassing, a feeling that there's no place to use. Most of the machines are idle, and the production lines are scattered."

Elder martial brother Zhao nodded, "well, I think so, too. If we get to the destination smoothly and get a lot of resources, we can use our weapons... "

After the visit, Zhang Yuan had a general idea of the whole industrial system.

They continued to get on the bus and passed the astronomical observatory, where some astronomers were making astronomical observations.

There are no lighthouses or satellite signals in the universe. We can only determine our position by observing the stars in the sky.

But the whole galaxy is not still, it is also moving and spinning. If the direction of motion is a few microseconds away, we may eventually have to travel tens of billions of kilometers more. So it needs a lot of calculation and observation to judge accurately.

Zhang Yuan thought, "according to the date, our spacecraft should be in Mars orbit, right?"

Zhao Qingfeng nodded, "almost, it has been more than a month, want to go in and have a look?"

Zhang Yuan had to lament the greatness of the earth age. When he stayed in it, he could not feel that he was in the universe.

There is always a kind of The wonderful illusion that I still live on the earth.

This is actually a good thing. If you constantly remind yourself that there is a fatal danger around you in the universe, the psychological pressure will increase sharply. When depression spreads on a large scale, it will be troublesome.

At Mars orbit, the delay in communication with earth is about four minutes.

It takes four minutes for the sent message to reach the earth, and it takes four minutes for the earth to receive the reply message, so the time for information exchange is eight minutes.

When Zhang Yuan communicated with the earth, he usually used the form of short video.

"Go into the observatory and have a look."Zhang Yuan flew carefully to the observatory.

A bright starry sky is overhead. Here, we can have the closest contact with the universe of Weian.

It's very quiet inside the observatory, or in other words, every part of the gravity free zone is very quiet. It's just that sometimes there's a rustling sound coming out of the headphones.

Under the irradiation of ancient stars, witnessing the brilliance of the whole galaxy, there is an alternative sense of tranquility.

This kind of quiet, can let restless mind immerse down.

If you observe the earth with the naked eye, you will find that the earth has become a very common little star, and the sunlight reflected at a certain angle shows a light blue.

In a way, it's a bit like Sirius.

Mars is about 60 million kilometers away from the spacecraft. It looks a little bigger than the earth. The reflected sunlight is orange.

Through astronomical telescopes, you can even see the space city "Mars 3" above Mars!

Mars 3, once the prototype of the earth age spacecraft, is a mobile space city.

It's only one-third the size of the earth age, but it's enough for the technicians inside.

The future space city will be designed according to the concept of "mobile".

If you zoom in on the whole solar system, you will find Mars. It's too common. It doesn't have much development value for human beings.

From the perspective of space industry, Mars can't match the moon. The moon is close enough to the earth, with convenient transportation, low gravity, no atmosphere and abundant resources.

From the perspective of available resources, Mars can't compare with Europa and Titan.

Near Europa and Titan, there are large gaseous planets with endless warehouses of natural nuclear fuel.

Titan has countless hydrocarbons on it. If we can exploit the planet, we will have a lot of oil. A large amount of easily exploitable organic matter is quite valuable.
