Five Hundred and Thirty Eight Work Arrangements

It took a day to install the functional cabin, and the gravity far below the earth brought a lot of convenience to the installation work, but the heavy spacesuit also brought a lot of trouble to everyone.

After setting up all the functional cabins, the tired astronauts returned to the living cabin. After a brief tidying up, Gao Kai called everyone together and said bluntly: "Comrades, from today onwards, this is our home. , according to the plan, we have to be divided into three groups."

Having said that, he deliberately paused to see if other people had any opinions.

In fact, Gao Kai did not need to be so cautious. He was the first head of the lunar surface construction team appointed by the ground. Unless it was a matter of principle, no one would raise any objections.

Seeing that no one spoke, Gao Kai continued: "The first group is directed by me, with Lu Hao as a member..."

"Here!" Lu Hao raised his hand to signal.

"Zhang Hui!"

"arrive!"

"Lu Yang!

"arrive……"

Gao Kai named a total of seven people's names: "Okay, I will form an excavation team with you and be in charge of 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 the research group, headed by Hu Liang, and the team members are Liu Junming and Yuan Yu, responsible for equipment maintenance and logistics support, this is the moon, any negligence will punish us Death penalty, you must ensure the safe operation of all equipment."

"Don't worry, no problem." Hu Liang said.

"The third group is the water collection group. The group leader Ye Han, and the group members Xu Hua and Duan Zhiyang, do you have any questions?"

"Drawing water?" Ye Han was taken aback, "How do you draw water?"

"There is a frozen lake 500 meters to the south. Your task is to find a suitable place to excavate water ice, melt the ice and then electrolyze it... It's up to you whether we have oxygen or not." Gao Kai said with a breath action.

Ye Han nodded: "Understood."

"Who has any questions?" Gao Kai glanced across the crowd, "If not, let me introduce the situation...don't be so serious, just relax a bit,

Feel free to ask any questions. "

Everyone laughed together, and the original serious atmosphere became a little looser.

Gao Kai continued: "Everyone should know that this is the North Pole of the Moon, but you may not know it. 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 Pit No. 1."

"No wonder I had to see the sun, I thought it was the polar night."

"It is indeed polar night at the moment." Gao Kai said, "There are craters blocking it, and the sun cannot shine here during polar day, otherwise the water in the frozen lake would have dried up long ago."

As we all know, there are many "seas" on the surface of the moon. These so-called seas are actually the great plains on the moon, and the north and south poles of the moon are full of craters. It is not difficult to find a suitable rock mountain. The difficulty is to find one with ice lakes. crater.

The moon has no atmosphere, and naturally there is no air pressure. As long as the water ice melts, it will enter a boiling state. Although the heat taken away by the intense vaporization will cause the water to refreeze, as long as there is sunlight, this process will continue to repeat. No matter how much water It has long since disappeared due to vaporization.

Only in the polar environment where there is no sunlight can there be a chance to accumulate some water ice.

"Is the ice lake big?" Ye Han asked curiously.

"It's not small, but it was only me and Hu Liang before, and we didn't have time to investigate the reserves of the ice lake. You can check it." Gao Kai said.

"Understood." Ye Han nodded, "But there is no light here, where does the electricity come from?"

The space station can use photovoltaic battery packs to solve the power problem. There is little light in the polar regions of the moon, and the camp is still hidden in the crater. No matter how many photovoltaic cells there are without light, it is useless.

"We don't have photovoltaic cells, but we have a small metal pile. I dare not say anything else. We have as much electricity as we need." Gao Kai said, "Now all the equipment on the moon is powered by electricity, even excavators have to be dragged A cable, we can't do anything without this reactor... Wasn't there any information when you came here?"

"No." Ye Han said, "Maybe it's for keeping secret."

Gao Kai smiled noncommittally: "Then let me talk about the situation of the base. You don't need to tell me that everyone knows that the environment on the surface of the moon is very harsh. It doesn't make any sense to build a ground base in the conventional sense here. Our task is to dig an underground base. I don’t need to say more about the benefits, right?”

Several people nodded at the same time.

The underground base has many natural benefits. Hiding underground can not only play the role of concealing the base, but also the lunar soil and rock layers on the surface of the moon also have a very good protective effect, making maximum use of the natural conditions of the moon.

"When you talk about underground bases, you may think of the honeycomb bases in sci-fi movies, but I must tell you that it is impossible. Although the average thickness of the lunar soil is only ten centimeters, we lack the geological data of the moon. , I don’t know where the rock formation is suitable for excavating the base.”

"Then what should we do?" Duan Zhiyang asked.

"It's very simple. Just like digging an air-raid shelter, find a suitable mountain and dig in horizontally. After the mountain is hollowed out, digging down or spreading horizontally is trivial."

Everyone suddenly realized.

In a special period, air-raid shelters were dug desperately all over the country, and civil air defense projects left over from that year can be found everywhere. The entrance and exit of 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 doesn't have a drill bit, and it uses lasers to cut rocks. The efficiency is very high, but the power consumption is too poor. Without a nuclear reactor, it can't be used at all."

"Where are the stones dug out? How to transport them out?"

"There is a set of conveyor belts, which are refitted from coal equipment, and they are sure to work. If it doesn't work, let the ground find a way to send a new set of equipment up." Gao Kai said, "The excavated gravel doesn't need to be transported away, just pile it up outside. The main component of this crater is mare basalt, which is rich in iron and titanium and will be useful 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."

"Probably that's all." Gao Kai said.

The actual situation is naturally not as simple as Gao Kai said. For example, if the underground base is not dug up, 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, it will cause air loss in the base. , and even lead to a decrease in air pressure, which can lead to danger.

Therefore, the base must consider the issue of airtightness, do airtight treatment on the excavated walls, and apply a layer of glue, lacquer and other coatings that can play a sealing role.

In short, there is a long way to go.
