Chapter 83

The machine ahead is the legendary industrial mother machine and the core of industry.

Master machine is a manufacturing machine and machine. It is usually used to manufacture all kinds of high-precision machine tools. It is the top priority of restarting civilization.

However, this thing is also sealed. Under normal circumstances, it will not be opened.

The one around is a heavy metal 3D printer. It is also the only super large machine running at present. 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, objects are constructed by layer by layer printing using adhesive materials such as powder metal or ceramics.

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

"This student can only see, not touch. Don't move. You can't afford to lose it! "

One of the staff saw Zhang Yuan looking around and quickly 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 very perfect. It's just that I still hate it.

Elder martial brother Zhao said with a smile, "Lao Li, why? This is my younger martial brother. Pay attention! "

"Hello, senior brother Li." Zhang Yuan shouted quickly.

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

Without smiling, Lao Li looked at Zhang Yuan and said, "these are the top big toys. If you want to study, you can greet me, as long as you don't sneak in and mess with them!"

"Several foreign interns sneaked into the warehouse and almost started the industrial machine, which blew me up."

Elder martial brother Zhao smiled and asked, "what happened later?"

Elder martial brother Li snorted: "I wanted to call the police and let them force them to hibernate, but looking at their crying, I was soft hearted and let them go again..."

Elder martial brother Zhao looked back and joked: "Lao Li is a very soft person. If you pretend to be poor, 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 poor.

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

The whole factory on the first floor has almost the same place to visit. There are also the second floor, the third floor, the fourth floor and so on under the spacecraft. They are mineral smelting and light industry production factories, which can be visited later.

Zhang Yuan was also embarrassed to disturb others' work. He took elder martial brother Zhao and left in a hurry

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

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

"But it's embarrassing. It feels like there's no place to use it. Most of the machines are idle and the production lines are scattered."

Elder martial brother Zhao nodded, "Alas, I think so too. If we successfully arrive at the destination and obtain 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 is no lighthouse or satellite signal in the universe. You can only determine your position by observing the stars in the sky.

But the whole galaxy is not static, but also in constant motion and rotation. The difference in space navigation is thousands of miles. If the direction of motion is so different by a few microseconds, it may eventually have to travel tens of billions of kilometers. Therefore, it needs a lot of calculation and observation to judge accurately.

Zhang Yuan's heart moved, "according to the date, our spacecraft should be in the position of Mars orbit?"

Zhao Qingfeng nodded, "almost, it's been more than a month. Do you want to go in and have a look?"

Zhang Yuan had to lament the greatness of "earth times". Staying inside, he couldn't feel that he was in the universe.

There is always a wonderful illusion that... You still live on the earth.

This is actually a good thing. If you remind yourself that you are in the universe all the time, there are fatal dangers around, and the psychological pressure will increase sharply. When depression spreads on a large scale, it will be in trouble.

At the position of Mars orbit, the communication delay with earth is about 4 minutes.

It takes 4 minutes for the information sent to reach the earth, and 4 minutes for the earth to reply after receiving it, so the time for information exchange is 8 minutes.

When Zhang Yuan communicates with the earth, he usually adopts the form of short video.

"Go into the observatory and have a look."

Zhang Yuan carefully flew to the observatory.

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

It's quiet inside the observatory, or everywhere in the weightless zone. It's just that sometimes there's a rustling sound in the headset.

Under the irradiation of ancient stars, I witnessed the brilliance of the whole Milky way, and produced an alternative sense of tranquility.

This tranquility can immerse the restless mind.

Observing the earth with the naked eye, you will find that the earth has become a very ordinary little star, and the sunlight reflected at a specific angle presents a light blue.

In a way, it's a little similar to Sirius.

Mars is about 60 million kilometers away from the spacecraft, looks slightly larger than the earth, and the reflected sunlight presents an orange color.

Through the telescope, 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 times, but it's enough for the technicians inside.

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

If you look into the whole solar system, you will find that Mars is too common. It has no great development value for current humans.

From the perspective of space industry, Mars is not comparable to 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 is not comparable to Europa and Titan.

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

There are countless hydrocarbons on Titan. If we can exploit the planet, it is equivalent to having a lot of oil. Massive quantities of easily mined organic matter are still quite valuable.
