It took a day to install the functional module. The gravity far lower than the earth brought a lot of convenience to the installation work, but the heavy spacesuit also brought a lot of trouble to everyone.
After placing all the functional modules, the tired astronauts returned to the living module. After a brief tidying up, Gao Kai called everyone together and said bluntly: "Comrades, from today on, this is our home.
,According to the plan, we must be divided into three groups."
At this point, he paused deliberately to see if other people had any opinions.
In fact, Gao Kai does not need to be so cautious. He is the first leader of the lunar surface construction team appointed by the ground. Unless it is a matter of principle, no one will raise objections.
Seeing that no one was speaking, Gao Kai continued: "The first group is commanded by me, and the member is Lu Hao..."
"Here!" Lu Hao raised his hand to signal.
"Zhang Hui!"
"arrive!"
"Lu Yang!
"arrive……"
Gao Kai called the names of seven people in total: "Okay, I will form an excavation team with you and be responsible for the excavation project. Do you have any questions?"
"No!" replied a few people in the first group.
Gao Kai continued: "The second group is the support group or research group. Hu Liang is the leader. The team members are Liu Junming and Yuan Yu. They are responsible for equipment maintenance and logistics support. This is the moon. Any negligence will be punished by us.
Death penalty, you must ensure the safe operation of all equipment."
"Don't worry, it's no problem." Hu Liang said.
"The third group is the Jishui group. The leader is Ye Han, and the members are Xu Hua and Duan Zhiyang. Do you have any questions?"
"Drawing water?" Ye Han was stunned, "How to draw water?"
"There is an ice lake five hundred meters due south. Your task is to find a suitable place to dig out water ice, melt the ice and electrolyze it... It's up to you whether we have oxygen or not." Gao Kai said and gestured for breath.
action.
Ye Han nodded: "Understood."
"Who has any questions?" Gao Kai glanced at everyone, "If not, let me introduce the situation... Don't be so serious, just relax. If you have any questions, just ask."
Everyone laughed together, and the originally serious atmosphere relaxed a little.
Gao Kai continued: "Everyone should know that this is the North Pole of the Moon, but you may not know that we are now located in a crater with a diameter of more than 30 kilometers, surrounded by mountains on all sides. This place is temporarily named Crater 1."
"No wonder I can't see the sun. I thought it was the polar night."
"It is indeed the polar night now," Gao Kai said. "It is blocked by the crater, so the sun cannot shine here during the polar day, otherwise the water in the glacial lake would have dried up long ago."
As we all know, there are many "sea" on the surface of the moon. These so-called seas are actually the great plains on the moon. The north and south poles of the moon are full of craters. It is not difficult to find a suitable rock mountain. What is difficult is to find one with a glacial lake.
crater.
The moon has no atmosphere and naturally has no air pressure. As long as the water ice melts, it will enter a boiling state. Although the heat taken away by violent vaporization will cause the water to refreeze, as long as there is sunlight, this process will continue to repeat. No matter how much water is added,
It's all gone due to vaporization a long time ago.
Only in polar environments where there is no sunlight can one have the opportunity to accumulate some water ice.
"Is the ice lake big?" Ye Han asked curiously.
"It's not small, but it was just Hu Liang and I before and we didn't have time to investigate the reserves of the glacial lake. You can check it out." Gao Kai said.
"I understand." Ye Han nodded, "But there is no light here, where does the electricity come from?"
The space station can use photovoltaic batteries to solve the power problem. There is little light in the lunar poles, and the camp is still hidden in the crater. No matter how many photovoltaic cells there are, it is useless without light.
"We don't have photovoltaic cells, but we have a small metal pile. I can't say anything else, but we have as much electricity as we need." Gao Kai said, "Now all the equipment on the moon is powered by electricity, and even the excavator has to be towed.
A cable, without this reactor, we can't do anything...Didn't anyone introduce these situations when you came?"
"No." Ye Han said, "Maybe it's to keep it secret."
Gao Kai smiled noncommittally: "Then let me talk about the situation of the base. Needless to say, everyone knows that the lunar surface environment is very harsh. It makes no sense to build a conventional ground base here. Our task is to dig an underground base.
I don’t need to say more about the benefits?”
Several people nodded at the same time.
There are many natural benefits to underground bases. Hiding underground can not only serve as a hidden base, but the lunar soil and rock formations on the moon's surface also have a very good protective effect, maximizing the use of the natural conditions of the moon.
"When talking about underground bases, you may think of the honeycomb bases in science fiction movies, but I must tell you that that is impossible. Although the average thickness of lunar soil is only ten centimeters, we lack geological data on the moon.
, I don’t know where the rock formation is suitable for digging a base.”
"What should we do?" Duan Zhiyang asked.
"It's very simple. Just like digging a bomb shelter, find a suitable mountain and dig in sideways. Once the mountain is hollowed out, it's trivial to dig further down or spread it laterally."
Everyone suddenly realized.
During a special period, all over the country were desperately digging air-raid shelters, and leftover civil air defense projects can be found everywhere. The entrance and exit of the civil air defense projects are definitely not shafts, but gates opened on the mountain wall.
"What equipment do we use to dig the mountain?"
"Laser rock drill." Gao Kai said, "This thing has no drill bits. It uses lasers to cut rocks. It is very efficient. However, it consumes too much power. Without a nuclear reactor, this thing cannot be used at all."
"What about the excavated stones? How to transport them out?"
"There is a set of conveyor belts, which are modified coal equipment. They will definitely work. If it doesn't work, let the ground find a way to send a new set of equipment." Gao Kai said, "There is no need to transport the excavated gravel, just pile it outside.
The main component of this crater is mare basalt, which is rich in iron and titanium and will be of great use in the future."
"I've heard of it." Ye Han nodded, "We have a certain understanding of the situation on the moon, but we don't know the construction plan."
"That's about it," Gao Kai said.
The actual situation is naturally not as simple as Gao Kai said. For example, if the underground base is dug, everything will be fine. Even if it is a whole piece of rock, there may be gaps. No matter how small or inconspicuous the gap is, it will cause the loss of air in the base.
, and even lead to a decrease in air pressure, which may cause danger.
Therefore, the base must consider the issue of air tightness, perform air sealing treatment on the dug walls, and apply a layer of sealing glue, paint, etc.
In short, there is a long way to go... Friends who read books, you can search for "" and you will find this site as soon as possible.
