In the next five hours, the lunar rover went to three other designated locations to take different samples and install instruments. Then, it returned to the lunar module to rest. At the same time, the Daqian Tang Taizong unfurled the solar sail to recharge the batteries.
However, the live broadcast of the moon landing ended here. Although there were still a few more days to go, the Solar System Technology Exploration Company announced that they would not broadcast their future activities.
Obviously, the Daqian or Hua Xia had more confidential experiments to do. If they broadcast it live, it was very likely that some clues would be leaked. Therefore, they gave up on the live broadcast.
This made countless intelligence agencies around the world busy. They desperately wanted to find out what the Daqian was doing on the moon.
So, what did the Daqian do on the moon?
Well, some things were not easy to talk about, so I won't talk about it here. Anyway, it was enough to make some forces around the world suffer.
However, there was one thing that had to be mentioned. That was, Jia Changtian left a Moon Palace on the moon's surface.
That's right, literally. Jia Chang Tian and the others used eight hours to build a palace on the surface of the moon. It was called the Moon Palace.
Of course, the palace was just a bluff. In fact, it could be understood as a large inflatable greenhouse. After it was fully opened, it was about 10 square meters in size. It was fixed at a place on the moon that changed day and night.
Because this place was relatively far from the landing point, it was very difficult to reach without the transportation of the lunar rover.
So, what was in this Moon Palace?
Very simple, a small biosphere.
Everyone must have heard of something like an ecological bottle. It was a glass bottle that put some small animals and plants into it. It was self-sufficient without adding any food. Without opening the bottle, all living things could survive. This was an ecological bottle.
It was sold on Taobao. The price was very cheap. You could buy it for a few dozen yuan. However, in about half a year to a year, the ecology inside would collapse. After all, the smaller the volume, the more fragile the ecology.
Also, there couldn't be any living animals in the ecological bottle. At most, there would be some microorganisms.
In addition, there were people on Earth who had done similar experiments. They had built a larger ecosphere and isolated the people outside the ecosphere from everything. The people inside the ecosphere could only rely on the things inside to survive. They wanted to see how long the ecosphere could last.
In the 1990s, the Americans built an artificial ecological circulation system in a desert in Arizona. It was called Biosphere 2.
However, please note that the reason why it was called Earth 2 was not because they had previously built Earth 1, but because Earth 1 was Earth itself, and they had built Earth 2. This showed how ambitious the builders of this experiment were!
The entire biosphere took eight years to build, covered an area of 12,000 square meters, and cost 150 million US dollars. It contained more than 3,000 species of animals and plants, as well as more than 1,000 species of microbes from all over the world.
After careful calculations and research, the researchers believed that as long as these things were properly arranged and their quantity and size were designed, they could form a completely self-sufficient ecosystem. Even if human beings left the earth, they could still survive in this ecosystem by relying only on sunlight.
According to the experimenter's plan, this ecosystem could last for at least 10 years.
However, the first entry only lasted for 21 months before the oxygen and nitrogen dioxide were completely out of balance. All the researchers had no choice but to withdraw.
They proposed improvements and modified the ecosystem. Then, they entered a second time. However, this time, they only stayed for nine months before withdrawing. The results were not as good as the first time. Many of the people who participated in the experiment even had different mental problems.
Therefore, many scientists asserted that it was almost impossible to build an artificial ecosystem.
However, this was something that humans had to do. Because if humans wanted to leave the earth in the future, they had to build an ecosystem that basically relied only on sunlight to survive. Otherwise, it would be difficult for humans to continue living on the surface of other planets, as well as in long-distance colonial fleets.
After all, the nearest planet that might be suitable for human habitation would require thousands of years of sailing with the current technology of humans. If there was no complete ecosystem during this period, it would not be possible.
Also, Jia Changtian's goal was to land on Mars. He also wanted to build a research base on Mars, so he needed a complete ecosystem even more.
Therefore, the biologists in the Daqian laboratory spent five years building another ecosystem, which was the Guanghan Palace that Jia Changtian and the others were responsible for.
This ecosystem was only ten square meters in size and was completely sealed with transparent plastic. It was filled with a specially designed mixture of carbon dioxide and oxygen. The oxygen ratio was slightly higher than the air on Earth.
However, optimistically, this ecosystem could last for more than ten years.
In addition, there were no more than five hundred species of animals, plants, and microorganisms. The largest creatures were two turtles. These two turtles were very small turtles that grew very slowly. They did not eat much and grew very slowly. In ten years, they could grow to the size of a palm. They were the animals that had the highest chance of surviving in this ecosystem.
At this time, they were still living leisurely in the Guanghan Palace. They had no idea that they were the first pair of turtles to live on the moon.
It was unknown if there were rabbits on the moon, but there were definitely turtles now. It was just that they did not know how long they could live on the moon.
However, words were not enough, and they needed evidence. If they tested it on Earth, it would be inevitable that there would be a lot of dark spots. Therefore, Jia Changtian decided to directly move the Guanghan Palace system to the moon.
If this Guanghan Palace could really last for ten years on the moon, then humans would have the ability to build larger Guanghan Palaces on other planets that could sustain human survival.
At the same time, a complete monitoring system was installed in this ecosystem. There was also a set of information transmission system. At the same time, Jia Changtian would leave all of the Daqian Tang Taizong's batteries to this ecosystem for these systems to use. This would allow them to transmit real-time data back to the laboratories on Earth for analysis.
This was one of the most important Daqian experiments on the moon. One could imagine how many people would try to get their hands on the relevant data once the news of this experiment was released. After all, this was related to the main technology for human migration to outer space and other planets in the future. Therefore, it had to be kept secret.
Other than that, there were also some other experiments in the Daqian Technology Center. They were all done in these few days.
In the blink of an eye, it was almost time to go home. Today, Jia Changtian and Wang Jiawei drove the Daqian Tang Taizong to the last location to collect data.
Suddenly, Wang Jiawei turned around and found that he had lost track of Jia Changtian.
At first, Wang Jiawei did not think much of it. After all, in outer space, there were many situations where one could suddenly lose track of one's teammates. It happened before, and Jia Changtian quickly appeared on his own.
However, after more than twenty minutes, Jia Changtian still had not been found. Wang Jiawei was a little anxious. He called Jia Changtian's communicator, but there was no reply. It meant that he could not find the other party's signal.
"F * ck!" In an instant, Wang Jiawei was sweating profusely. He remembered the accident when they landed on the moon's surface. They also lost all contact in an instant.
