Chapter 41 Great Migration
The erosion of time is the cruelest. Whether you escape or cherish it, it will not change with human will. The hurried and busy six months passed quickly, and even delayed a few more days, but people's space projects must be completed.
Professor Thomson, who is responsible for astronomical observations, has issued multiple warnings in succession. Several large meteorites have begun to cross the Lagrange limit and have a great probability of hitting the moon. Humans must leave immediately!
These meteorites and the moon attract each other, forming a complex multi-body motion. This kind of motion is extremely sensitive to initial values, called chaos, and it is difficult for humans to get an accurate solution. But the danger is real, and the sooner you leave, the safer you will be.
In the heart of Yu Yifeng, the captain of the Noah, there is a strong and complex feeling of parting. Humans are about to leave their hometown, and it is likely to leave forever and never come back. This is also the thought in the hearts of many people. When they work, they often reveal a fleeting sense of melancholy.
However, this is also helpless. Humans must step into the universe and find their own sky.
From the perspective of the satellite, you can see that the entire base has changed a lot. The original round glass cover had long been removed, replaced by a huge deep pit, with a silvery white sphere lying quietly in the center of the deep pit.
It is the last home of mankind - Noah!
It is too big and too spectacular. The sphere with a diameter of 15 kilometers is 7.5 times longer than the original base and occupies half of the entire meteorite crater. Without considering other technologies, such a large volume alone is not something that humans can make.
The tallest building in the human race - the Burj Khalifa, is 828 meters high, only one eighteenth of it, which can be said to be just a tiny thing. The two shapes of sphere and cone represent different technological contents. The round spacecraft is the most difficult to build.
Its surface is almost completely smooth, which means that the friction is very small, so no dust can be contaminated on the surface of the hull. The whole spacecraft looks sparkling and has a heart-stirring beauty.
But because there is no friction and it is hard enough, it brings certain difficulties to people's construction. No cement or paint can be directly pasted on it. Without friction, it will fall off as soon as it is applied, even the most powerful glue of mankind is no exception.
Smart scientists have come up with another way. They can't build outside, but they can build inside. People built a lot of thick cement pillars inside the spacecraft, and then extended the reinforced concrete from the entrances and exits of the spacecraft.
Relying on these extended structures, people indirectly built a lot of things on the surface of the spacecraft. Like the engine room, cockpit, observation room, and some laboratories, etc. These auxiliary structures are made of titanium-aluminum alloy, which is very light, but hard and reliable.
Yu Yifeng is even a little glad that this spacecraft has more than 2,000 entrances and exits. Without these, humans can't even build anything on the surface of the spacecraft.
This is the difference between heaven and earth in technology.
The civilization that built this spacecraft is really unimaginable to humans. In front of this super civilization, humans may really be like a paramecium.
I have to say that this is a pessimistic thought, but it is also a fact. Facing the vast universe, humans are still too immature.
The "engine" at the bottom of the spacecraft is a bit like a large washbasin. However, this "basin" is upside down, and it contains a large amount of gas and a billion-ton helium-3 nuclear bomb!
The diameter of the basin is about one kilometer. This volume has been carefully calculated. It is not good to be too big or too small. Don't think that the spacecraft has a diameter of 15 kilometers and the engine is only this small. The mass of the spacecraft is really too light compared to its volume, and the overall density is not as good as a balloon.
Therefore, such a small engine is enough.
All instruments are undergoing final testing, and hundreds of testers in space suits are busy.
Yu Yifeng inspected the warehouse again. Billions of tons of ore were piled up in the spacecraft like a small mountain. The entire uranium resource mine was almost emptied, which was enough for human use for 20 to 30 years. The ice resources at the bottom of the spacecraft were also mined out, and about 100 million tons of ice were obtained. The remaining food is enough for human consumption for two or three years.
But Yu Yifeng still felt that it was not enough. He always had a sense of insecurity. Perhaps this is the common feeling in everyone's heart. In the vast space, humans will not get any material supplements, and no matter how much, it is not enough.
It's like when a wanderer leaves his mother for the first time, he always carries a lot of things, no matter how well prepared he is, he is still nervous.
If everything goes well, it will take three or four months to reach Mars, and people can get resources by then, so there is no need to be so nervous.
Yu Yifeng comforted himself and continued his inspection.
From the inside, the entire spacecraft facilities can only be said to be unsatisfactory. Because of gravity, the entire residential area is divided into three parts: upper, middle and lower. The gravity at the top is the lowest, about the same as the moon, and the gravity at the bottom is the earth's gravity.
This is because people have not yet adapted to the gravity of the earth. Living in the low gravity environment of the moon, calcium in the bones will gradually be lost, and muscles will gradually atrophy. If you suddenly arrive at the gravity zone of the earth, you will often be like paralyzed and unable to stand up.
Therefore, everyone needs a gradual adaptation process. The first batch of people who moved in have completely adapted to the gravity environment of the earth.
As for people's living environment, it cannot be said to be very good. After all, six months is too short for people to build high-rise buildings. Necessary life-support equipment, such as oxygen circulation system, water circulation system, power system, sewage treatment system, etc., took a lot of time to build these things, and there was no time to improve the living environment!
It is not the lack of wealth that is worrying, but the inequality. In order to prevent such a thing, Yu Yifeng simply waved his hand and everyone slept in a tin house, even himself.
This simple and easy-to-make house, which can be surrounded by a few pieces of tin sheets, is the kind that workers often sleep in on the construction site. It cannot be said to be comfortable and not very soundproof, but at least it can block some.
No one is dissatisfied with this phenomenon. Captain Yu Yifeng himself lives in such a house. What else can he say? Are you more awesome than the captain of Noah's Ark?
By the way, the name of this spaceship is Noah because it comes from the story in the Hebrew Bible? Genesis, which means the ship that saves the world. And this time, it is also a spaceship that saves mankind.
"Report to the captain! The engine system has been checked and no errors have been found. Please give instructions!"
"Report to the captain! The power system has been checked and no errors have been found!"
"Captain, all the people have been arranged for accommodation."
...
One by one, the test reports came up, and no abnormalities were found. It's time to leave. Yu Yifeng tapped the table with his fingers and said with emotion: "You go and broadcast a notice. From now on, everyone is free to move around, and the time they stay on the ground must not exceed midnight."
"Tomorrow at 8 o'clock, officially set sail!"
"Yes!"
As soon as this notice was given, a large group of people got off the spaceship. They were wearing space suits and staggering on the moon. Some took photos of the spacecraft, some took photos with each other, and some sketched, having a great time.
People knew that the time spent on the moon would never come back, so they cherished it especially, as it was the last commemoration.
