Deep Space Fleet

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

The mother machine is the 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 in storage, and under normal circumstances, it will not be opened.

The one next to it is a heavy metal 3D printer, and it is also the only ultra-large machine currently in operation. It can be used to produce some not particularly complicated parts.

3D printing is a rapid prototyping technology based on digital model files, using bondable materials such as powdered metal or ceramics to construct objects by layer-by-layer printing.

That is to say, after the device is designed from the computer, it will automatically spit out various parts and assemble it.

"This classmate, you can only look at it, you can't touch it, and don't touch it. You won't be able to afford it if you break it!"

Seeing Zhang Yuandong looking around, one of the staff quickly issued a warning.

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

Flying around this place, if it hits something,

Although it's not a big deal, the security protection of the industrial zone has been done very well. But it's still annoying.

Brother Zhao scolded with a smile: "Lao Li, what are you doing? This is my junior brother, show some respect!"

"Hello Senior Brother Li." Zhang Yuan called out hastily.

Every place in this production room is an important position with intensive knowledge, technology, and talents. The minimum education level is a Ph. D., and it is nothing to be called a senior.

Reaching out without hitting the smiling face, Lao Li glanced at Zhang Yuan and said, "These are top-notch big toys. If you want to study them, you can call me, as long as you don't sneak in and mess with them!"

"A few foreign interns sneaked into the warehouse and almost started the industrial machine, but I was blown away."

Brother Zhao asked with a smile, "What happened next?"

Senior Brother Li snorted: "At first I wanted to call the police and force them to hibernate, but seeing them crying bitterly, my heart softened for a moment, and I let it go..."

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

Zhang Yuan stared 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 rely on his acting skills for a living. From now on, he can only win with his strength.

The entire first floor is almost the place to visit the factory. There are second, third, and fourth floors under the spaceship, which are mineral smelting and light industry production factories. You can visit them later.

Zhang Yuan was also embarrassed to disturb other people's work, so he dragged Senior Brother Zhao and left in a hurry...

"After reading this, what do you think?" Brother Zhao immediately asked.

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

"But it's very embarrassing, a feeling of strength and nowhere to go. Most of the machines are idle, and the production lines are scattered."

Senior Brother Zhao nodded, "Oh, I think so too. If we reach the destination smoothly and obtain a lot of resources, then we will be of great use..."

After the visit, Zhang Yuan already had an overview of the entire industrial system in his mind.

The two continued to board the car and passed by the astronomical observatory, where some astronomers were making astronomical observations.

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

But the entire Milky Way is not static, it is also constantly moving and rotating. In space travel, the difference is thousands of miles. If the direction of movement is a few microseconds different, it may end up traveling tens of billions of kilometers more. Therefore, a large number of calculations and observations are required to make a more accurate judgment.

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

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

Zhang Yuan couldn't help feeling the greatness of the "Earth Times", staying in it, he didn't feel that he was in the universe at all.

There is always a kind of... the wonderful illusion that I am still living on the earth.

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

At locations orbiting Mars, the communication delay with Earth is about 4 minutes.

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

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

"Go into the observatory and have a look."

Zhang Yuan flew up to the observatory cautiously.

A bright starry sky is just overhead. Here, you can have the most intimate contact with the stalwart universe.

It's very quiet inside the observatory, or rather, every place in the zero-gravity zone is very quiet. It's just that sometimes there is a rustling sound from the earphones.

Under the illumination of the ancient starlight, witnessing the brilliance of the entire Milky Way gave rise to an alternative sense of tranquility.

This kind of tranquility can immerse the restless mind.

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

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

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

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

"Mars 3" used to be the prototype of the "Earth Age" spacecraft, a mobile space city.

Its volume is only one-third of that of the Earth Era, but it is enough for the technicians inside.

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

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

From the perspective of the space industry, Mars is not as good as 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 as good as "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 this planet can be exploited, it is equivalent to having a lot of oil. A large amount of easy-to-mine organic matter is still quite valuable.
