Wandering Spaceship in Deep Space Chapter 104: The unknown night

　　 So, should I eat it up before hibernation, or after waking up from hibernation, enjoy the good time?

　　How to achieve the highest degree of satisfaction while reducing the risk of deterioration and other issues? This is a difficult mathematical problem.

　　 I am extremely boring. Zhang Yuan has been constructing a "satisfaction function" and a "deteriorating risk function" in his mind, trying to obtain a higher degree of satisfaction at the cost of two kilograms of beef jerky.

Half a quarter of an hour later, there was a soft "bang", the elevator they were carrying had reached the surface, and the outside temperature displayed on the instrument was minus 170 degrees Celsius.

　　 "Mr. Zhang, I can only send you here."

　　 "Maybe I will never see each other again, can you...hug?" The little girl who was in charge of receiving Zhang Yuan hesitated for a while, and whispered in his ear. Nothing happened in the past few days, and she still felt it was a pity.

　　 Zhang Yuan was taken aback, opened his hands, and hugged the girl who had just known each other for five days.

　　 Enduring the pain, he still gave her some beef jerky in his hand.

　　 "Thank you for your care these days, I will give you this little gift."

　　 The girl jumped up happily: "Ah, you are such a good person! I haven't eaten the earth's beef jerky for a long time... Well, everything here is expensive..."

　　From her surprised eyes, it can be known that this thing is placed on Europa, which is definitely a resounding "luxury".

　　It’s no wonder that the organizer will treat them as small gifts.

　　 Europa has started to breed some livestock, but in order to maintain the health of the ecosystem, the output is bound to be low.

　　"It's just a little beef jerky. It's nothing."

　　 Zhang Yuan feels sad, they, astronauts, may also have to face such a bleak tomorrow.

　　 Maybe... even more bleak.

　　 "A good trip!"

　　 nodded slightly, Zhang Yuan turned and took the train to leave. From a distance, you could see the girl waving her hands inside the glass window.

　　 The space elevator is hundreds of kilometers away.

　　 "Goodbye!"

　　 Along the way, you can see all kinds of busy construction site scenes.

　　The flames of nuclear fusion have been ignited on this planet, and the next development is only a matter of time.

　　With the efforts of generation after generation, this place will become another home for mankind.

　　 Maybe...

　　 Europa has many flaws compared to the earth. The surface here is full of ice, and there is no shortage of water resources, but the planet is abnormally lacking in metal elements, rare earths and organic matter.

　　The current mineral mining companies can only develop some large meteorite mines that fall on the surface. However, the reserves of these meteorite mines are all quite limited, and they will be gone after mining.

　　 Jupiter has another relatively large moon Io, which makes mining even more difficult.

　　 Io is similar in size to Europa and is an earth-like planet, but numerous super volcanic activities and super earthquakes frequently occur, making it an extremely dangerous planet.

　　No one will invest in an unstable place. Maybe a few years of work, a super earthquake, make all investment go to waste.

　　From this perspective, there is still considerable room for improvement in the level of human interstellar development.

　　If there is enough capacity to calm volcanoes and earthquakes, there are still many places to live in the solar system...

　　 "Brother Zhao, I noticed that maybe due to improper maintenance, some people are seriously degraded, and their muscle lines are not the same as normal people." When taking the space elevator back to Earth Age, Zhang Yuan asked quietly.

　　"Such a large body change may cause some irreparable damage. Even if it is finally returned to the earth, it will be difficult to recover, right?"

　　 This question has been lingering in my heart, and I don’t have time to ask, but when I ask it, it seems to be relieved.

　　 Under low gravity conditions, the pressure on the intervertebral disc caused by the weight disappears between the vertebral bodies, the compression of the intervertebral disc is released, and the person becomes taller.

　　 Normally, as long as the damage is not serious, the height of the astronaut will return to normal after returning to Earth.

　　 But the low gravity environment will have a series of effects on gene expression. For some severely degraded people, they may no longer be able to adapt to the earth's environment.

　　 "Did you find out..." Zhao Qingfeng thought for a while, and said in a low voice, "Do you think they will be from the Xia country?"

　　 "It looks like it shouldn't be. I don't understand what they are saying."

　　"Will it be American or Lanzhou?"

　　 Zhang Yuan shook his head, "It shouldn't be."

　　 "Then who do you think they will be and where are they from..."

　　 may be... some small country?

　　 thought for a while and suddenly realized.

　　 Behind all the glamour, there are countless unknown nights.

　　 The salaries of normal technicians here are too high, starting with an annual salary of one million. And most people's contracts are only three years, and they will eventually return to Earth.

　　Three years is actually a little too short of the development cycle of several decades. Frequent personnel flow~IndoMTL.com~ is definitely not good for the entire development project.

　　 In this case, for the entire civilization and certain capitalists, there are bound to be some more "money-saving" and "economical" ways.

　　 Even though the current automation industry is quite developed, the role of humans cannot be easily replaced in a complex environment.

　　 Zhang Yuan asked quietly: "These people have already settled here?"

　　 "Yes, from the beginning, it has existed decades ago."

　　"Why would anyone like this?"

　　 Senior Brother Zhao smiled, and exclaimed: "What you think is good or bad, whether you want it or not, is just relative. Why do people want to live in poor mountains and bad waters? Why do people live on high slopes of loess? Why? Does anyone still live in the countryside, not in the city?"

　　"Compared with the past, what’s so bad about living here? As long as you sell your labor, you can at least not have the trouble of starving to death, and you can live a more enjoyable life than on earth. There are more promising..."

　　 Zhang Yuan was silent, and found himself asking a stupid question. He asked again: "So, can they reproduce offspring?"

　　 Brother Zhao looked around for a while, and then said, "It is said that it is possible."

　　 paused for a while, and he added, "With the current medical level, it's okay. It's just a little risky, and the chance of pregnancy is not high."

　　 There was dead silence in the air. Zhang Yuan originally wanted to ask, under such drastic environmental changes, will the evolution from generation to generation create reproductive isolation and form different races?

　　 But after thinking about it, he swallowed again.

　　 Physiological screening will take at least tens of thousands of years, right? Asking him to consider this question is indeed a bit overwhelming.
