In the next five hours, the lunar rover went to three other set locations, conducted different sampling, installed instruments, etc., and then returned to the lunar module to rest. At the same time, Daqian Tang Taizong also unfolded the solar sail to charge.

However, the external live broadcast of the moon landing ends here. Although there are still several days of itinerary to go to the future, the Solar System Technology Exploration Company announced that all future itineraries will not be broadcast live.

It is obvious that Daqian or China have more confidential experiments to do. If you are running a live broadcast, clues may be leaked, so you simply give up the live broadcast.

This made countless intelligence agencies around the world busy, trying their best to figure out what Daqian did on the moon.

So what did Daqian do on the moon?

Well, some things are hard to say, so I won’t talk about them here. Anyway, they are enough for some domestic and foreign forces to drink a pot of food.

However, there is one thing that must be said, that is, Jia Changtian left a Guanghan Palace on the surface of the moon.

That's right, it's literally. Jia Changtian and his team spent 8 hours building a palace on the surface of the moon, named Guanghan Palace.

Of course, the palace is just a boast, and can actually be understood as a large inflatable greenhouse. After it is fully expanded, it is about 10 square meters and is fixed on the moon with a relatively average day and night change.

Because this place is far from the landing point, it is difficult to reach without the transportation of the lunar rover.

So what is in this Guanghan Palace?

Very simple, a small biosphere.

Everyone must have heard of ecological bottles. They put some small animals and plants into a glass bottle, and are self-sufficient, without adding any food or opening the bottle, and all living things can survive. This is the ecological bottle.

It is sold on Taobao, and the price is very cheap. You can buy it for a few dozen yuan. However, the ecology inside will collapse in about half a year to a year. After all, the smaller the size, the more fragile the entire ecology is.

Moreover, there are no living animals in the ecological bottle, at most, there are some microorganisms.

In addition, some people on Earth have done similar experiments to build a larger ecosystem to isolate people inside and outside the circle from everything, and the people inside only rely on the things inside to see how long they can last.

In the 1990s, the Americans established an artificial ecological circulation system in a desert in Arizona, named Biosphere No. 2.

But please note that the reason why he called him No. 2 is not because he built No. 1 before, but because No. 1 is the earth itself. They built No. 2. This shows how great the ambitions of the builders of this experiment are!

The entire biosphere construction took 8 years, covers an area of ​​12,000 square meters, costs US$150 million, has more than 3,000 animals and plants, as well as more than 1,000 microorganisms, from various regions around the world.

After careful calculations and research, the researchers believed that as long as these things are arranged reasonably and their quantity and size are designed, they can form a completely self-sufficient ecosystem, so that even if humans leave the earth and rely solely on the sunshine, they can survive in this ecosystem.

According to the experimenter's plan, this ecosystem can last for at least 10 years.

But after only 21 months of entry, oxygen and nitrogen dioxide were completely unbalanced, and all scientific researchers had to withdraw.

They put forward suggestions for improvement, transformed the ecosystem, and then entered the second time. As a result, they retreated after only 9 months. Their grades were not as good as the first time. Many people who participated in the experiment even had different mental problems.

Therefore, many scientists assert that it is almost impossible to build an ecosystem manually.

But this is something that humans must do, because in the future, if humans want to leave the earth, they must build an ecosystem that can basically survive by relying solely on the sun. Otherwise, it will be difficult for humans to live on the surface of other planets and in long-distance colonial fleets.

After all, to go to the nearest planet that may be suitable for human habitation, with the current technology of human beings, it will take thousands of years to sail to arrive. This period will not be possible without a complete ecosystem.

Also, Jia Changtian aims to land on Mars as his goal, and he also wants to build a scientific research base on Mars, which requires a complete ecosystem even more.

So the biological experts of Daqian Laboratory spent five years to create another ecosystem system, namely the Guanghan Palace arranged by Jia Changtian and others.

This ecosystem is only 10 square meters in size and consists of completely sealed transparent plastic. It is filled with a designed gas mixed with carbon dioxide and oxygen. The oxygen ratio is slightly higher than the earth's air.

But optimistically, this ecosystem can last for more than 10 years.

In addition, there are only more than 500 animals and plants and microorganisms in it. The largest organism is two turtles. These two turtles are small turtles that grow very slowly. They don’t eat much and grow slowly. They may grow to the size of their palms in 10 years. They are the animals that are most likely to survive in this ecosystem.

At this time, they were still living leisurely in Guanghan Palace. They had no idea that they were the first pair of turtles living on the moon in the world.

I don’t know if there are rabbits on the moon, but there must be turtles now, but I just don’t know how long they can live on the moon.

It’s just that the words are unfounded and evidence is needed. If you test it on the earth, it will inevitably lead to many dark situations under the lights. So Jia Changtian decided to move the Guanghan Palace system directly to the moon.

If this Guanghan Palace can really last on the moon for 10 years, then humans will have the ability to build a larger Guanghan Palace on other planets that can maintain human survival.

At the same time, this ecosystem is equipped with a complete monitoring system and an information transmission system. At the same time, Jia Changtian will leave all the batteries of Daqian Tang Taizong to this ecosystem for use by these systems so that data can be transmitted back to the internal ecosystem in real time and analyzed to the Earth's laboratory.

This is one of the most important experiments on the moon this time. It can be imagined that once the news of this experiment is released, how many people will try their best to get relevant experimental data. After all, this is the main technology related to future human immigration to outer space and other planets, so it must be kept confidential.

In addition, there are some other experiments from Daqian Technology Center, which have been done in the past few days.

In the blink of an eye, it was time to go home. On that day, Jia Changtian and Wang Jiawei drove Daqian Tang Taizong to collect data at the last location.

Suddenly, Wang Jiawei turned around and found that he had lost Jia Changtian's trace.

At first, Wang Jiawei didn't care. After all, there were many situations in space where teammates suddenly couldn't be seen. They had appeared before, and Jia Changtian soon appeared by himself.

However, after more than twenty minutes, he still did not find Jia Changtian. Wang Jiawei became a little anxious and called Jia Changtian's communication, but there was no answer, indicating that the other party's signal could not be found.
