.

Qiang woke up from a pleasant sound of music, which he customized before going to bed

He opened his eyes and saw from the transparent mask that Du Zisheng was bound to his seat and was sleeping soundly. The other seats were empty, and it seemed that they had already gone out.

Although everyone still has to wear space suits for a certain period of time, they finally arrived at their destination and the dawn was ahead.

The days of sleeping in a space suit will not be too long.

Xiao Qiang untied his restraints and saw from the hatch door. Jiang Cheng was dutifully guarding next to the air detector. He turned his back to him in vain and wanted to wipe it clean, floating over, and the lunar dust absorbed onto the detector could not be wiped clean.

Xiao Qiang jumped off the spaceship, his body fluttering as if he had performed his light skills, and gently hit the ground.

There was no sound wave of air transmitting on the moon, and Jiang Cheng turned his back to him and did not notice that he had already come down from the spacecraft.

Xiao Qiang turned on the internal telephone and asked, "Jiang Cheng, where have the others gone?"

"Mr. Xiao, you're awake!" Jiang Cheng turned around and looked in from the transparent mask. He was in good spirits. "Mr. Wang and his team were eager to inspect the surrounding environment. Han Kun accompanied them and took care of them."

"It's still early and our base has not been established. What should we investigate?" Xiao Qiang complained in a low voice.

"It's getting late. Wang Zheng inspected the flight log. The moon's daytime is about 130 hours, only more than five days. There are still many things we have to do. If we don't hurry up, we may have to work in the dark. So Wang Zheng inspected the three-dimensional three-dimensional picture of the back of the moon and took the others to hurry over. Check the terrain on the spot and set up a front station for the next step of building a base." Jiang Cheng looked at the Crater with envy, licked his lips, as if he wanted to follow him.

The back of the moon is not like the front, there are craters everywhere, rugged and uneven, and the moon sea is pitifully few.

They landed in this place, right next to a circular crater that was thousands of meters high.

The crater is next to a continuous mountain. The highest point of the mountain is more than 5,000 meters. The mountain is majestic and steep, and it reaches thousands of kilometers in a row.

Some of these craters were formed by meteorite impacts, while others were formed by volcanic eruptions. The area where they landed was volcanoes within a radius of hundreds of kilometers.

This is a key area where the lunar volcano erupted hundreds of millions of years ago, and there are relatively many underground caves.

Some cave entrances are just on the edge of a volcano. They are shaped like caves.

Xiao Qiang's eyes were very good, and there was no air barrier on the moon. He soon found several moving white dots at the foot of the huge mountain. He jumped and went in that direction.

The spacesuits bind joints and movement cannot be as convenient as on Earth. They want to move, most of them have slightly bent their calfs and jump forward like kangaroos.

Wang Gong and the others had actually heard Xiao Qiang and Jiang Chengdi's conversation. There was no large amount of clutter from the earth on the back of the moon. The radio signal could be transmitted far away. They stood and waved their arms to Xiao Qiang. They stood there waiting for him.

"Mr. Wang, you are moving quickly. Let's go and explore the terrain together." Xiao Qiang said breathlessly.

Although the gravity on the moon is only one-sixth of that of the earth, it is very inconvenient under the constraints of the space suit. When moving, it consumes physical strength.

Wang Gong smiled wryly and said, "The old man is not like you. He is young and strong. He has suffered so much in the past few months. If he doesn't find the base construction site, the old man may die."

Several people burst into laughter.

Among the eight people, except for Xiao Qiang and others who are strong in their health, the three researchers, although they are younger than Mr. Wang, have been studying for many years and are in poor health. In this way, they are still selected to be "strong"! There are many inconveniences in life on the moon. Everyone has been living in such a difficult time these days. They have long been looking forward to leaving the spacesuit and living at home comfortably.

This is also what they can do to talk about base construction in a relaxed tone.

If the power of the earth is used to build a lunar base, there is no problem with scientific and technological reserves, but the huge cost required to build a base is that no country can bear.

If Xiao Qiang hadn't made great efforts in base construction, the country wouldn't have dared to make such an ambitious plan.

Now, it is estimated that the news of Xiao Qiang's disappearance has spread all over the world, and it is hard to say whether this plan can be implemented.

The light spot data were revealed on the masks of several people. They turned on the light brain and looked for the nearby cave exit under the guidance of the positioning system.

"According to the data of the lunar probe, there are tens of thousands of molten holes in this radius of thousands of miles. There are more than a dozen molten holes below the volcano in front of us, and they are still connected to each other. However, according to the photos, there are only a few black spots at the foot of the volcano in front of us. It is judged that it may be the entrance of the cave. We just went over to see if the results of the detector were correct." Wang patiently explained the situation to everyone.

"Mr. Wang, will there be any danger in that cave?" Han Kun asked worriedly.

Several researchers laughed: "There is no air on the moon, and no life can survive. Volcanoes have not erupted for hundreds of millions of years. Apart from worrying about radioactive materials and rock drops, there is basically no danger."

"What about biochemical pollution?" Han Kun did not fully accept their statement and argued, "For the past billions of years, the moon has suffered countless impacts from space. Will there be any dangerous bacteria, substances such as the saplings that are blown into the molten cave by the solar wind."

While jumping forward as a kangaroo, Wang explained: "We humans have evolved for hundreds of millions of years and have experienced everything. They have already possessed a certain ability to resist pollution. Strictly speaking, pollution on the earth is much more serious than on the moon. We can live on the earth, but we have no reason to live on the moon, but we cannot survive. Of course, we will collect some samples later and go back for analysis."

While speaking, they arrived at the entrance of the first melting hole.

The molten cave is a passageway and passage wall of the gas contained in the volcanic eruption. All are solidified by volcanic lava, and are extremely hard volcanic rocks.

Back then, the American lunar landing personnel used special collection machinery to drill some core samples. A special drill bit was used to drill rocks on the earth, which was very easy. However, on the moon, they struggled for a long time to obtain eleven kilograms of rock samples. The hardness of the soil and rocks on the moon can be imagined.

This cave is not very high, only one person is more than one person tall. It is surrounded by hard volcanic stones and no floating soil.

Xiao Qiang and his friends entered with the lighting equipment they carried. The cold rock walls were as smooth as they were passing by.

Its rock texture is even more delicate than the best marble.

There was nothing in the cave, no opposite sex hiding in it, nor bats, no life, and lifeless.

Xiao Qiang and his team walked more than ten meters and had to withdraw.

This molten hole is just an outlet. After more than ten meters, it is a steep downward passage. I don’t know how deep it is. Xiao Qiang and others did not carry various climbing equipment. The spacesuits on their bodies also restricted their movements. It is obvious that they cannot continue to detect downwards.

Their spacesuits provide oxygen, which can maintain an hour and a half of outdoor activities for ordinary people. The round trip is more than twenty minutes. If it weren't for Xiao Qiang's mobile reserve, they would not be able to conduct long-term field detection activities.

In the soil of the moon, it is rich in iron oxide, 3 substances, oxygen, and elements. Xiao Qiang doesn't have to worry about reorganizing and not finding the material.

They spent half a day to explore the six melting holes within a few kilometers nearby.

Four of them are connected to underground molten holes, one of which is almost a downward slope, and a researcher almost fell into it. These holes do not meet the needs of base construction.

There is also a molten hole that is very wide and flat inside, but the hole entrance is extremely small, so one can only bend down and crawl in.

If there is a little surprise in such a small cave entrance, everyone will be sealed inside, which is obviously not suitable as a base construction requirement.

The molten hole they found was about six kilometers away from the landing location of the spacecraft. The entrance of the cave was three meters high and seven or eight meters wide. Everyone was very satisfied with it at a glance.

Entering inside, there was a layer of floating soil that went forward for two or three kilometers, turning around, without seeing the end.

"This melting hole is good." Xiao Qiang commented cautiously.

"Then build a base here!" Han Kun said anxiously. If he holds it in the space suit, he will be crazy.

Wang Gong looked at the dark passage in the distance and made no sound for a long time.

A researcher used an iron hammer to try to knock a rock from the stone wall as a sample. Another researcher was collecting the underground soil and taking it back for analysis. Another researcher used a hand-held topographic map to collect data on the cave passages and draw detailed topographic maps. At this time, he said: "It is not finalized yet. I can only say that there is a possibility of building a base here."

"Why?" Han Kun looked around in confusion. It was smooth and flat. In his opinion, it was the best place to build a base.

"We also have to send a lunar rover to explore in depth. It is best to find another exit. In this way, once an accident occurs, the entrance of the cave is closed, and everyone has another escape exit. Meteorites often hit the moon, and the back of the moon is more frequent. Be careful." The researcher slowly moved his position with an automatic terrain mapper, explaining.

"Is it a lunar probe - a remote control five?" Xiao Qiang clicked on the brain, opened the equipment database, and clicked on a lunar probe rover from the production site of an African base to confirm.

In order to implement this plan, he has covered all the achievements of the African base over the years.

"Yes! That's this one!" The researcher looked up at his own screen and confirmed.

The remote control fifth type is the fifth generation product after many modifications. It has been tested in the virtual lunar environment and is the most excellent one. This is a low four-wheel drive device. Except for a car bucket behind it, used for planting equipment, the other components are all made of an alloy frame. The whip-shaped signal antenna allows it to move within three kilometers of the signal transit device and is in a controllable state.

There is a three-dimensional lens on the car, which can capture the three-dimensional video signal and transmit it back.

There are drill bits, lighting, robots, various measuring instruments and other auxiliary equipment, which can perform a variety of exploration tasks.

The remote control five-type uses four-wheel drive, powered by liquid hydrogen batteries and electric motors. At its four corners, there is also a small ground rocket engine, which can provide short-term flight capabilities.

If it is just moving on the ground and no data collection activities such as drilling are carried out, it can provide seven-hour power support for remote control Five. However, if a rocket engine is used and flying in the sky, considering that the gravity on the moon is small, it can only continue to fly for fifteen minutes.

If you want to carry another load, every kilogram of load will reduce the flight time by twenty-six seconds.

"It has been five hours since we came out, so let's go out first." Xiao Qiang nodded and said to the other personnel.

Back at the entrance of the cave, there was already a 50-centimeter-high lunar exploration rover parked outside, which was the remote control fifth type.

There are also several signal transmission devices of triangular brackets next to it.

Xiao Qiang put the signal transmission device into the vehicle's bucket, one of which was built at the entrance of the cave. He left with everyone. On the way, in order to ensure that the signal transmission is not unexpected, he placed two signal transmission devices. It seems that even if other interferences are caused, the remote control vehicle can be accurately controlled.

The detection of the melt cave lasted for more than 20 days. They were buried on the spacecraft and used a remote control to conduct in-depth exploration of the cave.

During this period, there was a failure and the detection vehicle slid down from a slope. The landslide was very long. Although it did not destroy the detection vehicle, it exceeded the signal transmission distance. For this reason, Xiao Qiang could only come to the entrance of the cave under the escort of Du Zisheng and others on a moonlit night when he was unable to see his fingers. He put another detection vehicle in to place the signal transit device.

The cave is very deep, and there are many downward openings inside, and it is crisscrossed and unknown whether it leads to the heart of the moon.

Xiao Qiang provided ground signal devices and replenished them more than a dozen times, totaling hundreds. Later, the driving distance of the detection vehicle also exceeded the limit of battery power supply.

They could only build a supply station at the entrance of the cave and store all the necessary supplementary materials here.

Du Zisheng volunteered to go deep into the melting hole to establish a supply point. On the upper and lower passages, they all placed a lot of ropes for Du Zisheng to climb. This action is very dangerous. If you are not careful, the space suit will be damaged, and he will be in extreme danger.

Xiao Qiang is the focus of everyone's protection. In the words of Wang Construction Site, "It doesn't matter if my old man dies, Mr. Xiao must ensure absolute safety!"

Therefore, although he saw Du Zisheng in danger several times and wanted to help, he was forced to stop him. Han Kun, Jiang Cheng and other three took turns to ensure that the exploration of the molten cave could be carried out normally and quickly.

Finally, I found that there was indeed more than one ground exit of the melting hole, but four, with the farthest distance of more than fifty kilometers!

There are dozens of other closed passages, shaped like spider webs, extending around, but there is no ground exit exposed, which is just a dead end. It leads to underground caves, and I don’t know how many of them he has.

The place is likely to be just a very small part of this complex network. Whether this is the main hole or not is difficult to determine.

But this is no longer important. What is important is that they have found a place that can be built as a base.

And on this day, they have been on the moon for six months and three days!

These days, they have not only fully explored the plane network of melting holes, but also surprisingly, they have discovered ice!

It was when the exploration car used a rocket device to fly to the next ladder, and the light accidentally shone into a cave below. The picture flashed by, but everyone screamed in surprise.

When Han Kun controlled the detection car to the ground, they quickly turned the video signal back to the previous part.
To be continued...
