Chapter 106

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

How to achieve the highest satisfaction and reduce the risk of deterioration is a difficult mathematical problem.

It's very boring. Zhang Yuan has been constructing "satisfaction function" and "deterioration risk function" in his mind, trying to get a higher degree of satisfaction at the cost of two kilograms of beef jerky.

Half a quarter of an hour later, the "boom" sounded softly. The elevator they took had reached the surface. The outside temperature displayed on the instrument was minus 170 degrees Celsius.

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

"I may never see you again. Can you... Give me a hug?" The little girl in charge of receiving Zhang Yuan hesitated for a while and whispered in his ear. She felt it a pity that no story had happened these days.

Zhang Yuan was stunned, opened his hands and hugged the girl who had just met for five days.

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

"Thank you for your care these days. I'll give you this little gift."

The girl jumped up happily: "ah, you are really a good man! I haven't eaten beef jerky from the earth for a long time... Alas, everything here is very expensive... "

From her surprised eyes, we can know that this thing is definitely a loud "luxury" on Europa.

No wonder the organizers treat them as small gifts.

Although Europa has begun to raise some livestock, the yield must not be high in order to maintain the health of the ecosystem.

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

Zhang Yuan was dejected that they astronauts might have to face such a bleak tomorrow.

Maybe... Worse.

"Bon Voyage!"

With a slight nod, Zhang Yuan turned and took the train to leave. From a distance, he could see the girl waving her hands in 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 flame of nuclear fusion has been lit on this planet, and the next development is only a matter of time.

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

Maybe

Compared with earth, Europa also has many defects. The surface here is full of ice, and there is no shortage of water resources, but the planet is extremely lack of metal elements, rare earths and organic matter.

At present, 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 also has another relatively large moon Io, which is even more difficult to mine.

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

No one will invest in an unstable place. Maybe in a few years, a super strong earthquake will make all the investment drift.

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

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

"Elder martial brother Zhao, I noticed that some people's bodies degenerate seriously because of improper maintenance. Their muscle lines are different from those of normal people." Zhang Yuan asked quietly as he took the space elevator back to the earth times.

"This huge physical change may cause some irreparable damage. Even if you finally return to the earth, it will be difficult to recover?"

This question has been lingering in my heart. I don't have time to ask it. At this time, it seems to be a sigh of relief.

Under the condition of low gravity, the pressure on the intervertebral disc caused by weight between the vertebral bodies disappears, the compression of the intervertebral disc is released, and people will become higher.

Usually, as long as the damage is not serious, the height of astronauts will return to normal after returning to earth.

However, 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.

"Have you noticed..." Zhao Qingfeng thought for a moment and whispered, "do you think they will be Xia people?"

"It seems that it shouldn't. I can't understand what they say. "

"Can it be American or LAN?"

Zhang Yuan shook his head. "It should not be."

"Who do you think they will be and where they come from..."

Maybe... Some small countries?

After thinking for a while, I suddenly realized.

Behind all the bright and beautiful, there are countless unknown nights.

The salary of normal technicians here is too high. The annual salary of one million starts. And most people's contracts are only three years and will eventually return to earth.

Three years is actually a little less than the development cycle of decades. Frequent personnel mobility is certainly unfavorable to the whole development project.

In that case, for the whole civilization and some capitalists, there must be some more "money saving" and "economic" ways.

Even though the current automation industry has been quite developed, the role of man can not be easily replaced in a complex environment.

Zhang Yuan asked quietly, "these people have settled here?"

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

"Why would anyone want to?"

Elder martial brother Zhao smiled and sighed, "what you think is good or bad, whether you are willing or not, is only relative. Why would anyone want to live in a poor place? Why do people live on high loess slopes? Why do some people still live in the countryside, not in the city? "

"Compared with the bitter days in the past, what's wrong with settling here? As long as you sell your own labor force, at least you can't have the trouble of starving to death, and you can live a meaningful life, which is more promising than the earth... "

Zhang Yuan was silent and found himself asking a stupid question. Then he asked, "can they reproduce?"

Elder martial brother Zhao looked around and said, "it's said that you can."

After a pause, he added, "it's OK with the current medical standard. It's just a little risk. The probability of pregnancy is not high. "

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

But after thinking about it, he swallowed it again.

Physiological screening, at least tens of thousands of years? It's really a bit too much for him to think about it.
