Just as Changgang Qingyi is throwing a billion-dollar order and feels desperate in life, the moon is more than 300,000 kilometers away, but it is a festive celebration. The atmosphere.

Under the gaze of the staff of the Yuegong and all the lunar scientific research stations, Wu Gang, wearing a spacesuit, skillfully operated a heavy-duty engineering vehicle connected with two pairs of mechanical arms to place the assembled track parts in the On the t-track excavated by the shield machine.

"Good job!"

Hearing the excitement of shouting from the passage, Wu Gang smiled faintly and skillfully controlled the joystick, and steadily disconnected the robotic arm and received it.

The same operation, he has been repeated countless times, naturally there can be no mistakes.

The engineering vehicle was turned backwards by about ten meters. Wu Gang turned off the engine and squinted at the direction of the skyline.

The track is hundreds of kilometers long and travels almost along a straight trajectory.

Just like a silver needle, it pierced this chaste jade plate. Drill in from one side of the lunar soil, drilled from the other side, and point to the earth-moon transfer orbit.

According to the engineering data disclosed by the lunar scientific research station, the maximum depth, that is, the depth of the central section of the track, can reach 1 km.

With a solid lunar surface, this design is designed to avoid the threat of meteorites to the greatest extent possible while meeting the launch needs.

Simply put, they cut through a satellite - albeit on its surface.

Minerals mined from the moon will be able to directly illuminate the earth-moon transfer orbit by electromagnetic acceleration through the vacuum track across the surface of the lunar surface, saving a large amount of chemical propellant.

By the time the moon landing activity and the lunar mining form a scale, this track will become the transportation hub of the entire Earth and Moon system, and the development plan of the Earth civilization for the moon will also enter the fast lane!

There is no doubt that this is a miracle in the history of engineering!

It is also a spectacle in the history of aerospace!

Of course, this track is not yet completed.

However, there is only one last section left...

......

Lunar scientific research station.

When the heavy-duty engineering vehicle was driven to the garage, Wu Gang unplugged the key on the car and pushed the door of the driver's seat.

Stepping on the arm of the ground, he grabbed the handle at the door with one hand and then jumped forward, skillfully jumping off the driver's seat of the truck.

Strictly speaking, this is not in line with the operating rules, the correct operation should be to climb down the ladder. However, staying on the moon for a long time will make people forget the feeling of height. Over time, no one cares about those things.

If it is on the earth, jumping down from the height of three or four meters, you will have to break a broken bone without breaking your leg.

But here, this point is nothing more than a pediatrics.

After replacing the cabin spacesuit, Wu Gang put on the cabin spacesuit with electromagnetic gravity belt and then passed through the airlock to the inside of the lunar scientific research station.

At this time, the young man named Xu Chengli had ran around with a can of water.

"Thank you."

He took the jug from his hand and inserted it on the nylon buckle on his chest. Wu Steel pulled out the straw and took a sip, then stuffed it back into the slot next to the collar.

With the captain Wu, I got on the elevator, Xu Chengli said with a smile.

"The celebration of Labor Day is about to begin. Today, the kitchen has made cabbage dumplings. If you have a good rest, let's hurry."

“Don’t worry,” Wu Gang took out the card and brushed it on the elevator door. He pressed the number on the dormitory floor and asked casually. “Speaking, there is a new work plan on the side of the Moon Palace.”

"Not yet! But I said, don't you rest for a while?"

“Resting?” Wu Gang looked back at the newly arrived engineer and said with a smile, “What is the rest here? I just want to finish the project.”

"After finishing it?"

"Go back to Earth for a while," Silence for a while, Wu Gang looked up and saw the number on the dial of the elevator. The pupil was printed with a trace of color. "My child is going to high school soon. I have been there for a long time." Didn't go back."

No matter how far you go.

The most difficult thing to leave is still the hometown...

......

The more people are out of the group, the more they are eager for the sense of ritual in life.

Only in this way will lonely people feel that they are not separated from their own ethnic groups.

In a sense, the people on the lunar expedition are a group of marginalized people who are exiled outside the civilized world. A one-second delay makes real-time communication an extremely difficult task, and valuable communication resources make it very limited for everyone to get information from the Earth.

Let people living here be able to call home for one and a half hours a week. It is already the Moon Track Construction Committee doing its best to get them welfare.

In addition, in order to ensure that the staff living here ensure a good psychological state, every festival, regardless of size, the management staff of the scientific research station will do everything possible to organize various activities and strive to make People living here feel the joy of the holiday and the warmth of the home.

Standing at the door, looking at the lively canteen, Yu Fei’s face showed a happy smile.

As the stationmaster of the lunar scientific research station, and the first "colonizer" who arrived at the moon, he looked at it more and more lively day by day. He believes that there will be a day in the future. The lunar scientific research station at his feet will become a lunar village, becoming a beacon and port for humans to spread the civilized fire to the farther world...

At this time, there was a voice behind him.

"In the stationmaster, how do you stand at the door, don't you go in and eat something?"

Yu Fei looked back and saw Dr. Yang Xingyu, who was stationed here from the earth some time ago, and smiled and said hello to him.

"I have already eaten it," responded to a polite smile. He continued, "Is Dr. Yang, how is your project going?"

“Very smooth,” Yang Xingyu said with a smile. “The dr-111 active material is very fond of the environment on the moon. By controlling the ratio of nitrogen, carbon dioxide and oxygen, we have already explored the gas environment that is most suitable for their reproduction. It should not take long. We can try to use these microbiota to transform the organic circulation system of our scientific research station."

"No problem, if there is any need, please tell me," said Dr. Yang, Yu Fei said solemnly, "When can our scientific research station become a colony, all of them can rely on your project progress." ”

"The webmaster said that dealing with the metabolite cycle is only one of the prerequisites for mass transfer of the population and labor force from the earth to the moon. If you want to really use this fertile land, there are still many things waiting for us to solve it. "Stop for a moment, Yang Xingyu continued, "Say, our lunar surface quality accelerator, how is it built? Can it be completed?"

This huge project started construction two years ago. Yang Xingyu still remembers that the first time he saw the term lunar mass accelerator was still on the headline of Renren Daily.

Now two years have passed, the collider that has dug through the crater has been completed for half a year, and I don’t know the legendary “moon cannon”.

When Dr. Yang Xingyu was asked about this matter, Yu Fei’s face finally showed a smile.

Unsurprisingly, the lunar surface quality accelerator is probably the biggest achievement of his terminology during the term of the station.

Responding to Dr. Yang Xingyu's curious eyes, he said with a sigh of relief.

"Before the National Day, there should be no problem!"
