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

The master machine is a manufacturing machine and machine, which is usually used to manufacture various high-precision machine tools, and is the top priority of restarting civilization.

However, this thing is also under seal and will not be turned on under normal circumstances.

The surrounding one is a heavy metal 3D printer, and it is also the only super-large machine currently operating. It can be used to produce some not particularly complex parts.

3d printing is a rapid molding technology based on digital model files and uses adhesive materials such as powdered metal or ceramics to construct objects through layer 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, not touch, and never move around. If you ruin it, you can't afford to compensate!"

One of the staff members saw Zhang Yuandong 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 is not a big deal, the safety protection of industrial areas has been very complete. But it is still very annoying.

Senior Brother Zhao laughed and scolded: "Old Li, what are you doing? This is my junior brother, please give me the priority!"

"Hello, Senior Brother Li." Zhang Yuan shouted quickly.

Every place in this production room is an important position with knowledge-intensive, technology-intensive and talent-intensive position. The minimum education is also a doctorate, so it’s nothing to call a senior brother.

After reaching out without slapping the smiling person, Old Li glanced 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 run in secretly and mess around!"

"Several foreign interns actually slipped into the warehouse and almost started the industrial mother machine, but I was so angry."

Senior Brother Zhao asked with a smile: "What's next?"

Senior Brother Li snorted: "I originally wanted to call the police and let them hibernate forcibly, but seeing their crying bitterly, I felt soft-hearted and let go again..."

Senior Brother Zhao turned around and joked: "Old Li is a person with very soft ears. If you pretend to be pitiful and shed tears of pain, and ask him to use a 3D printer to help you get a real machine out, it is not impossible..."

Zhang Yuan stared at his eyes and pretended for a long time, but found that he couldn't pretend to be very pitiful.

It seems that he has no way to make a living by acting skills. From now on, he can only win by strength.

The entire first floor of the factory is almost the same. There are also the second floor, the third floor, the fourth floor, etc. under the spacecraft, which are mineral smelting and light industrial production factories. You can visit them later.

Zhang Yuan was embarrassed to disturb others' work, so he pulled Senior Brother Zhao and left in a hurry...

"What do you think after reading these?" Senior Brother Zhao asked immediately.

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

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

Senior Brother Zhao nodded, "Oh, I think so too. If we successfully arrive at the destination and obtain a lot of resources, we can use our skills..."

After the visit, Zhang Yuan had a rough idea of ​​the entire industrial system.

The two continued to get on the bus and passed by the astronomical observation deck, where some astronomers were conducting 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 entire Milky Way is not still, and it is also constantly moving and rotating. The difference between space navigation is a slight difference of a thousand miles. If the direction of movement is different by a few microseconds, you may eventually have to go hundreds of billions of kilometers. Therefore, a lot of calculations are required and observations are required to make more accurate judgments.

Zhang Yuan's heart moved, "By the date, our spacecraft should be in the orbit of Mars, right?"

Zhao Qingfeng nodded, "It's almost a month since I've been there. Want to go in and have a look?"

Zhang Yuan had to sigh at the greatness of the "Earth Age". When he stayed inside, he could not feel that he was in the universe at all.

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

This is actually a good thing. If you remind yourself that you are in the universe and there are fatal dangers around you, your psychological pressure will be greatly amplified. At that time, depression will be spread on a large scale, which will be troublesome.

In the orbit of Mars, the communication delay with the Earth is about 4 minutes.

The message sent takes 4 minutes to reach the earth, and the message replied to the earth will also take 4 minutes, so the time for information exchange is 8 minutes.

When Zhang Yuan communicates with the earth, he usually uses the form of short videos.

"Let's go to the observatory to have a look."

Zhang Yuan flew to the observatory carefully.

A dazzling starry sky is above your head. Here, you can have the most intimate contact with the majestic universe.

It's very quiet inside the observatory, or in other words, every place in the gravity-free zone is very quiet. It's just that sometimes there are rustling sounds in the headphones.

Under the illumination of the ancient starlight, witnessing the brilliance of the entire Milky Way with one's own eyes, another feeling of tranquility has been created.

This tranquility can immerse the restless mind.

If you observe the earth with your naked eyes, you will find that the earth has become a very ordinary small star, and the sunlight reflected from a specific angle appears a light blue color.

From a certain angle, it is somewhat similar to Sirius.

Mars is about 60 million kilometers away from the spacecraft, which looks slightly larger than the earth, and the reflected sunlight appears to be an orange-yellow color.

Through the astronomical telescope, you can even see the space city staying above Mars - "Mars 3"!

"Mars 3" was once the prototype of the Earth Age spacecraft, a movable space city.

Its size is only one-third of that of the Earth Age, but it is completely enough for the technicians inside.

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

If you zoom in to the entire solar system, you will find that the planet Mars is too ordinary and does not have much development value for current humans.

From the perspective of space industry, Mars is not as good as the moon. The moon is close enough to the earth, has convenient transportation, low gravity, no atmosphere, and abundant resources.

From the perspective of available resources, Mars is not as good as "Europa" and "Tiang".

There are large gas planets near Europa and Titan, which have endless natural nuclear fuel warehouses.
