The erosion of time is the cruelest thing. Whether you escape or cherish it, it will not change with people's will. The hasty and busy six months passed quickly, and even a few more days were delayed, but
The human space project must come to an end.
Professor Thomson, who is in charge of astronomical observations, has issued multiple warnings in succession. Several large meteorites have begun to cross the Lagrangian boundary and have a high probability of hitting the moon. Humans must leave immediately!
These meteorites and the moon attract each other, forming a complex multi-body motion. This motion is extremely sensitive to the initial value and is called a chaotic phenomenon. It is difficult for humans to obtain an accurate solution. But the danger is real.
, leave early and be safe.
In the heart of the captain of the Noah, Yu Yifeng, there is a deep and complicated parting emotion. Human beings are about to leave their hometown, and it is very likely that they will leave forever and never come back. This is also the thought in the hearts of many people.
When they work, they often show a fleeting sense of melancholy.
However, there is nothing we can do about it. Human beings must move towards the universe and find their own sky.
From the perspective of the satellite, you can see that the entire base has changed drastically. The original circular glass cover has long been removed, replaced by a huge pit, and a silver-white ball is lying quietly in the pit.
The most central.
It is the last home of mankind - the Noah!
It's too big and spectacular. The sphere with a diameter of 15 kilometers is seven and a half times longer than the original base and occupies half of the entire crater. Regardless of other technologies, such a large size alone is not human.
It can be done.
The tallest building in mankind - the Burj Khalifa, with a height of 828 meters, is only one-eighteenth of it. It can be said to be just a small thing. The two shapes of sphere and cone represent different technological contents. The round shape
Spaceships are the most difficult to build.
Its surface is almost completely smooth, which means that the friction is very small, so no dust can be stained on the surface of the hull. The entire spacecraft looks sparkling and has a heart-stirring beauty.
But precisely because there is no friction and it is hard enough, it brings certain difficulties to people's construction. No matter cement or paint, there is no way to directly paste it on. Without friction, it will fall off as soon as it is applied. Even the most powerful human beings
Glue is no exception.
Smart scientists have come up with another way. It cannot be built outside, but it can be built inside. People built a large number of thick cement pillars inside the spacecraft, and then extended the reinforced concrete from the entrance and exit of the spacecraft.
Relying on these extended structures, people indirectly built many things on the surface of the spacecraft, such as the engine room, cockpit, observation room, and some laboratories, etc. These ancillary structures are made of titanium-aluminum alloy and are very
Lightweight, yet strong and reliable.
Yu Yifeng was even somewhat grateful that the spacecraft had more than two thousand entrances and exits. Without these, humans would not even be able to build anything on the surface of the spacecraft.
This is the difference between heaven and earth in technology.
The civilization that built this spaceship is so advanced that humans really cannot imagine. Facing this super civilization, humans may really be no more than a paramecium.
I have to say that this is a pessimistic thought, but it is also a fact. Facing the vast universe, human beings are still too immature.
The "engine" at the bottom of the spacecraft is a bit like a large washbasin. But this "washbasin" is turned upside down, and a large amount of gas is sealed inside, as well as a one-gigaton helium-3 nuclear bomb!
The diameter of the washbasin is about one kilometer. This volume has been carefully calculated. It is not good to be too big, and it is not good to be too small. Don't think that the diameter of the spacecraft is fifteen kilometers, and the engine is only so small. The mass of the spacecraft is really compared to its volume.
It's too light, and its overall density is worse than a balloon.
Therefore, such a small engine is enough.
All instruments are undergoing final testing, and hundreds of testers wearing spacesuits are busy.
Yu Yifeng inspected the warehouse again. Billions of tons of ore were piled up in the spacecraft like a hill. The entire uranium resource mine was almost hollowed out, enough for human use for twenty or thirty years. The ice resources at the bottom of the spacecraft were also empty.
Everything was harvested, and about 100 million tons of ice were obtained. The remaining food is enough for humans to eat for two or three years.
But Yu Yifeng still feels that it is not enough, and he always has a feeling of insecurity. Perhaps this is the common feeling in everyone's heart. In the vast space, human beings will not be able to get any material supplement, and no matter how much there is, it will not be enough.
Just like when a wanderer leaves his mother for the first time, he always carries a lot of things in big and small bags. No matter how well prepared he is, he is still nervous.
If everything goes well, we will reach Mars in three or four months. By then, people will be able to obtain resource supplements, so there is no need to be so nervous.
Yu Yifeng comforted himself and continued his inspection.
From the inside, the entire spacecraft facility can only be said to be unsatisfactory. Due to gravity, the entire residential area is divided into three parts: upper, middle and lower. The top one has the lowest gravity, about the same as the moon, and the bottom one has the earth's gravity.
This is because people have not adapted to the gravity of the earth. Once they are used to living in a low-gravity environment like the moon, the calcium in their bones will gradually lose and the muscles will gradually atrophy. If they reach the gravity area of the earth at once, they will often feel as if they are paralyzed.
, completely unable to stand up.
Therefore, everyone needs to go through a gradual adaptation process. The first batch of people who moved in have completely adapted to the earth's gravity environment.
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, electric power system, sewage sewage treatment system, etc.
It takes a lot of time to build these things, and there is no time to improve the living environment!
Worrying not about scarcity but about inequality, in order to prevent such and such bad things, Yu Yifeng simply waved his hand and ordered everyone to sleep in iron sheets, including himself.
This kind of simple and easy-to-make house is built with just a few pieces of iron sheets surrounding it. It is the kind where workers often sleep in construction sites. It cannot be said to be comfortable, and it is not very soundproof, but it can at least provide some protection.
No one is dissatisfied with this phenomenon. Captain Yu Yifeng lives in this kind of house, so 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 called Noah because it comes from a story in the Hebrew Bible Genesis, which means it is a ship that saves the world. And this time, it is also a spaceship that saves mankind.
"Report Captain! The engine system has been checked and no errors were found. Please give instructions!"
"Report to Captain! The power system has been checked and no errors were found!"
"Captain, all people have arranged their accommodation."
…
Test reports came up one after another, and no abnormalities were found. It’s time to leave. Yu Yifeng tapped the table gently with his fingers and said with emotion: "Go and broadcast an announcement. From now on, everyone is free."
Activities and stay on the ground shall not exceed twelve o'clock at midnight."
"At eight o'clock tomorrow, we will officially set sail!"
"yes!"
At this announcement, a large group of people got off the spacecraft. They were wearing spacesuits and walking staggeringly on the moon. Some were taking pictures of the spacecraft, some were taking photos with each other, and some were sketching and playing.
Very happy.
Everyone knows that the time spent on the moon will never come back, so they cherish it very much. This is the last memorial.
