It is liquid in the ice, and after it is sprayed out, it solidifies into the shape of snowflakes... This seems to be one of the physical properties of a certain gas, but Ye Han can't remember what it is specifically.
Ye Han's mind was filled with doubts. He shook the ice cubes in his hand and seemed to be able to hear the sound of liquid flowing.
Worried that the liquid gas would expand and break the ice, he carefully placed this special ice sample far away, returned to the sampling point, expanded the mining surface, and dug deeper into the ice.
When Duan Zhiyang rushed over to take the ice sample, Ye Han had already dug an ice pit more than two meters deep. Four large ice cubes that were hollow and contained liquid were neatly placed beside the pit.
A physical explosion is also an explosion. In order to avoid danger, Ye Han deliberately cut the ice cubes larger and used thick ice walls to restrain the liquid inside.
Duan Zhiyang was stunned: "What the hell is this?"
Ye Han smiled and climbed out of the ice pit: "It should be liquid air."
"How is that possible?" Duan Zhiyang felt very uncomfortable, "How did you get in?"
"I also want to know."
Duan Zhiyang asked in confusion: "Why are you digging so much?"
"There should be someone on the ground who is interested in this thing. Cut it out and keep it first to see what the ground thinks." Ye Han said.
"Okay, I'll find a place to leave it alone later."
"Don't forget to say, don't let Xu Hua get stuck in the machine." Ye Han instructed.
"Don't worry, how could I make such a stupid mistake!"
The lunar rover filled with ice samples first sent Ye Han to the next sampling point, and then returned silently.
Not long after, the temporary base, following instructions from the ground command center, cut open the ice bubble and analyzed the composition of the liquid inside. It was found that the liquid in the ice was just a mixture of liquid hydrogen and liquid helium, and also contained some solid nitrogen, which was considered a mixture of three gases.
.
Ye Han expressed great regret for this. Why was no liquid oxygen found in the vacuole?
However, what Ye Han didn't expect was that this kind of vacuole was not an isolated phenomenon. As the investigation progressed, the three groups discovered more vacuole structures. The composition of the liquid frozen in the ice was also diverse, some with a single composition, and others with different compositions.
It contains a variety of gases and has complex components. All liquids in ice bubbles have only one thing in common, which is that the melting point is lower than the ambient temperature.
After receiving the news, Ye Han suddenly realized that the air column sprayed out from the ice crevices contained 80% solid nitrogen, which is why the snowflakes appeared.
This was originally just a small episode at work, but a few days later, Ye Han dug out another opaque ice cube in the middle of the sampling point.
The area where the ice samples were collected belongs to a high-quality ice area. The quality of the water ice is extremely good. The white things in the ice immediately caught Ye Han's attention. After sending the ice sample back to the base for testing, he found that the opaque substances were actually
dry ice……
The magical ice lake once again refreshed Ye Han's outlook. He couldn't help but wonder what else was frozen in this seemingly calm ice lake.
As a result, that afternoon, he released the nitrogen ice sealed in the ice.
Ye Han was already calm about this. Unless another alien was dug out of the glacial lake, he felt that no matter what was in the ice, he would not be surprised again. But his discovery still shocked all the astronauts, and also
The command center was very surprised. Dry ice and nitrogen ice could still explain it, but experts racked their brains and could not determine under what conditions the ice layer sealed the liquid gas in the ice layer. But the experts came up with the idea of a small celestial body impact.
There are two hypotheses: theory and original environment theory to explain this phenomenon.
However, at this time, only a handful of people care about this issue. Even experts in the aerospace industry are more concerned about whether organic matter can be found in the ice than how many foreign objects are wrapped in the ice.
If organic matter can be found in glacial lakes, it will be of great significance to the study of the origin of organisms.
It's a pity that Beidu only pays attention to the construction progress of the lunar base. Whether there is air or mud in the ice is not considered by politicians at all. Even important water resources can only enter the scope of Beidu's concern after the lunar base is completed.
Politics is so realistic.
In the next week, the three groups completed half of the crater, collected hundreds of ice samples, and obtained a large amount of first-hand information. However, it still took a lot of time to complete the investigation task.
According to the plan, Kongtian-2 will be launched in the next few days. By then, the shortage of manpower at the base will be alleviated to a certain extent. All the astronauts, including Ye Han, are looking forward to it, and they can’t wait to return to Earth to send all the reserve astronauts back to Earth.
Drag it to the moon.
However, there were unforeseen circumstances. Just when Kongtian-2 was about to be launched, a tropical storm swept across the South China Sea, and the launch plan had to be postponed. The specific launch time depended on the weather.
The training base had selected the second batch of astronauts, but they were unable to launch because of the bad weather. After a few days, the storm subsided, and three of the twelve astronauts unexpectedly failed the physical examination, so they had to be replaced on the spot.
The astronauts were re-selected, and Kongtian-2 was finally launched.
Kongtian-2 arrived at the moon more than a week later than scheduled!
The second batch of astronauts did not merge into the temporary base, but started a new camp one kilometer away, and found another location to dig into the mountain wall.
The two bases were named Base 1 and Base 2 respectively, and the personnel were organized into teams one and two. They lived not far away, but without taking the lunar rover, a visit would be exhausting.
This is not in line with the previous construction plan, but it is the latest arrangement of Beidu.
Beidu plans to use all aerospace groups separately and dig caves at different locations on the crater. After the base is initially built, all the caves will be dug through to turn it into a lunar base with a large internal space.
Moreover, the functions of each cave are also arranged differently. As for the specific arrangements, no one knows. Everyone just needs to dig out the rocks according to the drawings.
The crater looks thin on the map, but its actual thickness is close to four kilometers. You can imagine how huge the base will be after it is completed.
Arranging astronauts in this way will definitely be more difficult, but the construction efficiency will be greatly improved. Who can join the space team without a little bit of political awareness? Even if you really have thoughts in your heart, you will never show it on your face, even if you are pretending, you can still pretend
Act like you are obligated to do so.
Group construction is equivalent to the introduction of a competition mechanism. The two groups immediately come to terms with each other, chasing each other to speed up the construction, and at least increase the construction efficiency by one-fifth!
Although there are two more people in the first team and the construction time is half a month earlier than that of the second team, it seems to be very disadvantageous to the second team. But when the second team moved in, the first team had already established a foothold. The support facilities already in the first base, the second team
There is no need for the team to waste resources on repeated construction. Whatever needs are provided by the first team.
Supplies and other supplies will be handled on the ground for the time being, and only Base 1 needs to supply enough oxygen.
