It took a day to place the functional cabin, and the gravity far below the earth brought a lot of convenience to the placement work, but the heavy spacesuit also brought a lot of trouble to everyone. Pen, fun, and www.biquge.info

After all the functional modules were placed, the tired astronauts returned to the living module, and after a brief tidying up, Gao Kai gathered everyone together and said bluntly: "Comrades, from today onwards, this is our home, according to the plan, we must be divided into three groups." ”

Speaking of which, he deliberately paused to see if the others had any opinions.

In fact, Gao Kai doesn't have to be so cautious, he is the first leader of the lunar construction team appointed by the ground, and no one will raise objections unless it is a matter of principle.

Seeing that no one spoke, Gao Kai continued: "The first group is commanded by me, and the members are Lu Hao......"

"Here!" Lu Hao raised his head.

"Zhang Hui!"

"Here!"

"Lu Yang!

"To ......"

Gao Kai named a total of seven people: "Okay, I will form an excavation team with you and be responsible for the excavation project, is there a problem?" ”

"Nope!" Several people from the first group answered.

Gao Kai continued: "The second group is the support group or research group, led 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 sentence us to death, you must ensure the safe operation of all equipment." ”

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

"The third group is the water drawing group, the leader Ye Han, the team members Xu Hua and Duan Zhiyang, are there any problems?"

"Draw water?" Ye Han was stunned for a moment, "What's the method?" ”

"There is an ice lake five hundred meters to the south, and your task is to find a suitable place to dig water ice, melt the ice and electrolyze it...... It's up to you whether we have oxygen or not. Gao Kai said with a breathing motion.

Ye Han nodded: "Understood." ”

"Who's in trouble?" Gao Kai's gaze swept over everyone, "If not, let me introduce the situation...... Don't be so serious, relax a little, and ask any questions. ”

Everyone laughed together, and the originally serious atmosphere loosened 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, and this place is tentatively named Cit 1. ”

"It's strange that I have to see the sun, I thought it was the polar night."

"It's really polar night right now." Gao Kai said, "There are craters in the way, and the sun can't 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 "seas" on the surface of the moon, and 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, and it is not difficult to find a suitable stone mountain, but it is difficult to find a crater with a glacial lake.

The moon has no atmosphere, 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 violent vaporization will cause the water to refreeze, but as long as there is sunlight, this process will continue to repeat, and no amount of water will run out due to vaporization.

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

"Is the glacial lake huge?" 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.

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

The space station can solve the power problem with photovoltaic cell packs, the moon's polar regions have little light, and the camp is still hidden in the crater, and no amount of photovoltaic cells has no light.

"We don't have photovoltaic cells, but we do have a small metal pile, and we don't dare to say anything else, how much electricity we need." "Now that everything on the moon is electrically driven, even the excavator has to drag a cable, and without this reactor, we can't do anything...... Didn't anyone tell me about this when you came? ”

"Nope." Ye Han said, "Maybe it's for secrecy." ”

Gao Kai smiled noncommittally: "Then let me talk about the situation of the base, I don't need to say that everyone knows that the surface environment of the moon is very harsh, and there is no point in building a ground base in the conventional sense here, our task is to dig an underground base, so 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, and the hidden underground can not only play the role of a concealed base, but also the lunar soil and rock formations on the surface of the moon also have a very good protective effect, making maximum use of the natural conditions of the moon.

"When it comes to underground bases, you may think of the kind of honeycomb bases in science fiction movies, but I must tell you, that's impossible, although the average thickness of the lunar soil is only ten centimeters, but we lack geological data on the moon, and we don't know where the rock formations are suitable for digging bases."

"What then?" Duan Zhiyang asked.

"It's very simple, just like digging an air-raid shelter, find a suitable mountain and dig it horizontally, and when the mountain is hollowed out, it is trivial to dig down or spread horizontally."

Everyone suddenly realized.

In a certain special period, all parts of the country desperately dug air-raid shelters, and the civil air defense projects left over from that year can be found in various places, and the entrance and exit of the civil air defense projects are definitely not vertical shafts, but gates opened on the mountain wall.

"What equipment do we use to dig the mountain?"

"Laser rock drill." Gao Kaidao, "This thing doesn't have a drill bit, it uses a laser to cut rock, and the efficiency is very high, but the power consumption is too poor, and you can't afford to use this thing without a nuclear reactor." ”

"What about the stone that was dug up? How to ship out? ”

"There is a set of conveyor belts, and the coal equipment is refitted, which must be easy to use, if it doesn't work, let the ground find a way to send a new set of equipment." Gao Kai said, "You don't have to transport the broken stones that are dug up, just pile them outside." The main component of this crater is the Moon Sea 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, the underground base is not dug and everything is fine, even if it is a whole rock, there may be gaps, no matter how small and inconspicuous the gaps, it will cause the air in the base to lose, and even lead to a decrease in air pressure, and then there is danger.

Therefore, the base must consider the problem of air tightness, do air tightness treatment on the dug wall, brush a layer of sealing glue, paint and other paints, etc.

In short, there is still a long way to go.
