I ask you to build tractors, but you build rockets?

Li Wei stood at the edge of the second explosion pit, squatted down and pressed the dust on the surface of the pit wall. He could not go deeper after pressing only one knuckle.

Due to the combined effect of 8 carefully placed nuclear bombs, the size of the No. 2 explosion pit is extremely amazing. According to the observation of the space station, its diameter has reached about 4,600 meters and its depth is about 577 meters!

The original No. 1 explosion pit was directly wiped out, and the edge of the No. 2 explosion pit was raised about seven or eight meters like a crater.

Standing at the edge of the explosion pit, Li Wei felt like there was a river valley in front of him that could not see the end, because the angle of sunlight also caused most of the bottom of the explosion pit to be covered by shadows, giving people a sense of abyss.

However, in fact, the coverage area of ​​the explosion pit is only 16 square kilometers, which is equivalent to a small lake. It is only because it is on the moon and created by humans that it can give people such a shocking force.

When the explosion occurred on the 12th, even the Yushu base, 200 kilometers away in a straight line, saw the pale flash of the nuclear explosion, and induced the highest magnitude 5.2 earthquake in the surrounding area. The vibration can be clearly felt. The power is earth-shattering compared with the first time, and the equivalent has increased by a full 160 times.

"Old Liu, we may have to report to the ground."

Li Wei carefully observed the slope. Theoretically calculated, it is about 25%, which is already a steep slope and has a significant impact on the operation.

Subsequent blasting requires a descent of at least two or three hundred meters to drill holes in the pit wall. The current equipment can barely cope with it, but from the perspective of space caution, it is more appropriate to develop some modification kits.

"The slope ratio is indeed a bit high. It is better to let robots work. Human operations will soon be unreliable."

Liu Ming thought more. When the depth of blasting continues to accumulate, the slope ratio will rise rapidly. According to the assumed limit, it will even be close to 1, that is, a steep slope of 45 degrees. It is estimated that even going down will require the help of professional equipment.

Nuclear bombs can blast out extremely smooth pits, but they cannot blast out the winding mountain roads around the mines on Earth, and they don't have the energy to build roads.

"That is a special operation vehicle... and we have to find a way to solve the emergency rapid ascent, hiss~"

Li Wei's voice was interrupted by a cry of pain. He is still in the action cycle of the 304 agent, that is, he is still changing teeth.

Even though this aspect has been greatly optimized, the pain of rapid tooth replacement is still unavoidable, especially since Li Wei did not take painkillers during the mission.

Liu Ming heard his cry clearly on the radio, and could not help but move his gums.

Liu Ming was the second to receive the injection, but it would take three or four days for him to start changing his teeth.

"Beep beep beep... This is the Yushu base, please answer if you hear it, beep beep beep... This is..."

A call sign suddenly came from the radio, and Li Wei quickly replied:

"I am Li Wei, received the signal, repeat, I am Li Wei..."

After almost a few seconds, Fu Xiangjie's voice sounded again:

"The new four team members have arrived, we have landed at the Yushu base, instructor, I apply to pick a piece of broccoli to entertain the new team members in the evening!"

Li Wei immediately remembered the news that a new batch of four permanent team members had set off two days ago. From the fourth day after the explosion, except for the permanent astronauts, the rest of the experts evacuated one after another, and at the same time, the ground sent the agreed new team members.

Two men and two women, all under the age of 35, clearly wanted the old team members to lead the new ones.

Li Wei was uniquely tolerant of the newcomers, and immediately replied:

"The cabbage should be ripe, take out our best things to entertain them, Liu Ming and I will be back in about eight hours, please rest as soon as possible, over!"

...

"Come on, welcome my junior brother!"

While Fu Xiangjie was talking to Li Wei, Deng Lei was warmly entertaining the four new team members, one of whom he was particularly familiar with.

Gao Qitao felt a little unnatural when he heard the name of junior brother, after all, Deng Lei was almost old enough to be his father, but from a work perspective, he was really a junior brother.

He is a 2017 graduate and one of the best talents trained by Xinyuan on his own. In the past year, he mainly participated in the design and implementation of the OGAS system.

When the ground discussed the follow-up team members a month ago, half of the four places were given to Xinyuan, and Shelev directly recommended him.

Another woman, Yu Jie, was a material major. After entering the work, she was sent to Qingshan Base and came to the moon to be trained as a nuclear engineer.

However, these two people are not experts now. They are working and learning on the moon. Xinyuan mainly hopes to cultivate space talents from the basics.

Although the one sent by the space agency is also young, the 28-year-old Zhang Xiaozhou is a young genius in the field of nuclear physics. He graduated with a doctorate at the age of 24. From the age of 20 to now, he has published many papers with high academic value. He has also participated in several cutting-edge projects and is a real mainstay.

Another quota is a 32-year-old woman named Zhang Qiuying, an electronics expert who also studied psychology and obtained a doctorate degree. She can provide psychological counseling services for the team members.

These four team members are still the first batch. There will be four more in the second batch, and there will be several more batches. It is expected that the number of astronauts stationed on the moon will reach about 20, including 12 in Yushu Base and 8 in Wutu Space Station.

As far as Deng Lei knows, this expansion plan should be completed within the year. As for replacement?

I don’t know about those sent by the space agency, but Deng Lei and Li Wei are all employees of Xinyuan Company. I still remember that in the last communication with the boss, Lin Ju said annual leave...

Xinyuan's mission cycle for the lunar resident astronauts is based on going to sea. It is tentatively planned to rest for two to four months a year after leaving the earth. Each astronaut has a family reunion quota every year.

This is also Lin Ju's suggestion to appease the mental health of employees. Within a work cycle, a relative can be designated to go to the workplace for a reunion of no more than 7 days. For the first time, applications are required to be made two months in advance so that the relatives can receive necessary training.

This benefit is still temporarily implemented in the name of Xinyuan Company, but Lin Ju is already planning to transfer it to United Mining.

Of course, Deng Lei and Li Wei already have this benefit and can use it this year. Deng Lei has already chosen his wife, while Li Wei is still hesitating.

Although there is no news about the remaining two team members, Li Wei does not think that the Aviation Development Committee is favoring one over the other and should still be discussing.

The main purpose of this benefit is to stabilize people's hearts. Lin Ju is very clear about the importance of the moon. It is very important to maintain a stable personnel composition. The first batch of team members may work for more than 10 years before moving.

Deng Lei was quite happy about this, and even looked forward to taking his son on a trip to the moon when he grew up to the required age.

Perhaps it was mixed with his own emotions, but his attitude towards newcomers was also extremely friendly.

"Welcome again, my colleagues, juniors, and comrades."
