Wandering Spaceship in Deep Space Chapter 79: Observatory

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

　　Mother machine is a manufacturing machine and a machine, which is usually used to manufacture a variety of high-precision machine tools, and is the top priority for restarting civilization.

　　 However, this thing is also in sealed storage, under normal circumstances, it will not be opened.

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

　　3D printing is a rapid prototyping technology, based on digital model files, using powdered metals or ceramics and other bondable materials to construct objects by printing layer by layer.

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

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

　　 One of the staff members saw Zhang Yuandong looking away and quickly issued a warning.

　　 They dislike visitors like Zhang Yuan very much.

　　 flying around in this place, if you really hit something,

　　 Although it’s not a big deal, the safety protection of industrial areas has long been done very well. It's just that it's still annoying.

　　 Senior Brother Zhao smiled and scolded: "Old Li, what are you doing? This is my Junior Brother, please respect!"

　　 "Hello Brother Li." Zhang Yuan called out quickly.

　　Every place in this production room is an important position with intensive knowledge, technology, and talent. The minimum degree is also a doctorate, so it’s not a big deal to call a brother.

　　 stretched out his hand not to hit the smiley man, Lao 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 sneak in and mess around by yourself!"

　　 "A few foreign interns sneaked into the warehouse and almost turned on the industrial machine, but I was blown up."

　　 Senior Brother Zhao smiled and asked: "What happened later?"

　　 Senior Brother Li snorted: "I wanted to call the police to force them to hibernate, but seeing them crying bitterly, I felt relieved and let go again..."

　　 Senior Brother Zhao turned his head and joked: "Lao Li is a person with very soft ears. If you pretend to be a little pitiful and shed painful tears, ask him to use a 3D printer to help you get a real machine out. It’s not impossible..."

　　 Zhang Yuan stared at him, pretending for a long time, and found that he could not pretend to be very pitiful.

　　 It seems that he can't rely on his acting skills to eat, and from now on, he can only win with his strength.

　　 The entire first floor of the factory tour is almost the same. Below the spacecraft, there are second, third, fourth, etc., which are mineral smelting and light industry production plants, which can be visited later.

　　 Zhang Yuan was too embarrassed to interrupt other people’s work, took Brother Zhao, and left in a hurry...

　　 "After reading these, what do you think?" 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 even more important than our lives!"

　　"But it is very embarrassing, a feeling that there is nowhere to be strong, most of the machines are in idle state, 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, we have our abilities..."

　　 After visiting, Zhang Yuan already had a general idea of ​​the entire industrial system in his mind.

　　 The two continued to get in the car, passing by the Astronomical Observatory, where some astronomers were doing 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 galaxy is not stationary, it is constantly moving and rotating. In cosmic navigation, the difference is a thousand miles away. If the direction of movement is a few microseconds away, it may eventually travel tens of billions of kilometers. Therefore, a lot of calculations and observations are needed to make a more accurate judgment.

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

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

　　 Zhang Yuan had to sigh with emotion about the greatness of the "Earth Age", staying inside, completely unable to feel being in the universe.

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

　　 This is actually a good thing. If you keep reminding yourself that you are in the universe and there are deadly dangers around you, your psychological pressure will be magnified sharply. When depression spreads on a large scale, it will be troublesome.

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

The message sent by 　　 takes 4 minutes to reach the earth, and it takes 4 minutes to reply to the message after the earth receives it, so the time for an information exchange is 8 minutes.

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

　　 "Let's go into the observatory and have a look."

　　 Zhang Yuan flew up to the observatory carefully.

　　A shining starry sky is just above my head. Here, you can have the most intimate contact with the stalwart universe.

　　 The observatory is very quiet, in other words, every place in the gravity-free zone is very quiet~IndoMTL.com~It's just that there are sometimes rustling sounds from the headphones.

　　, under the light of ancient stars, witnessed the brilliance of the entire Milky Way with my own eyes, and created an alternative sense of tranquility.

　　This kind of quietness 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 appears a light blue.

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

　　 And Mars is about 60 million kilometers away from the spacecraft. It looks slightly larger than the Earth, and the reflected sunlight is orange.

　　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 size is only one-third the size of the Earth Age, but for the technicians inside, it's quite enough.

　　Future space cities will be designed according to the concept of "movable".

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

　　From the perspective of the 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 as good as Europa and Titan.

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

　　 There are countless hydrocarbons on Titan. If this planet can be mined, it is equivalent to having a lot of oil. Massive amounts of easy-to-mine organic matter are still quite valuable.
