Annihilation of the solar system

Qiu Yusheng nodded repeatedly:

"No problem! There must be no problem! Team leader, please rest assured! Rest assured!"

Everyone laughed. While talking, they had arrived at the airlock leading to the equipment cabin. Everyone skillfully put on their helmets, put on their life cycle backpacks, and released the magnetic attraction. They passed through the airlock and arrived at the equipment cabin.

Not only is there no pressurization here, but the layout and living cabin are also different. Although the appearance is a semicircular arched cabin, the living area is divided into upper and lower floors, and there is no layering here.

There are several six-wheeled lunar rovers parked in the equipment cabin. Their wheels are as tall as an adult. Behind the lunar rover are two trailers that are three times longer than the lunar rover itself. The trailers are loaded with various items.

Mechanical equipment and supplies. Team leader Su Yang asked through the public radio channel while guiding his eight team members to board the tall lunar rover:

"Has the inspection of car No. 007 been completed?"

"Well! I've checked it twice! No problem, you're ready to go." A familiar voice came from the earphones.

Li Linjie looked around and suddenly found a familiar figure on the trailer behind him pulling the straps of the mechanical equipment. He shouted in surprise:

"Ke Guohao!"

Since the sound from the radio was not as discernible as the sound in the air, Ke Guohao looked around.

"Behind you!" Li Linjie said.

Ke Guohao turned around and had a surprise smile on his face. He jumped down from the one-meter-high trailer, then slowly fell to the ground like a feather, and then jumped up to Li Linjie:

"Long time no see, Lin Jie!"

Although they haven't seen each other for only a week, for brothers like them who have never been separated since the first trial training, this week is really not a short time. Li Linjie smiled and nodded:

"Yes! How are you doing? Are you still used to it?"

Ke Guohao still had a sunny smile on his face:

"Well, great! My hard work on earth for more than a year was really not in vain. I like it here so much! What about you? Are you going on a mission?"

Li Linjie had a shy smile on his face:

"Yeah, it's my first mission, so I'm a little nervous."

Ke Guohao patted Li Linjie's arm gently through the space suit:

"It's okay, you can do a good job! I believe in you. I am now responsible for the maintenance of the lunar rover and construction machinery of your construction department. We will definitely see each other often in the future. By the way, have you seen Wanqing?"

Li Linjie shook his head:

"No, last week's acclimatization training was very busy, so I guess she was also very busy."

Ke Guohao pretended to have a look of lovesickness on his face:

"I'm afraid I won't have the chance to see her until my monthly physical examination!"

"Lin Jie, get in the car. It's just you!" Su Yang behind him shouted through the radio.

"Okay, here you go!" Li Linjie replied to the team leader, and then said to Ke Guohao:

"I'm about to leave. I'm currently living in cabin C 2022. Come find me when you have time."

"Not far away, I'm also in cabin C, 1053. See you later!"

After bidding farewell to Ke Guohao, Li Linjie boarded the tall lunar rover. The cockpit of this lunar rover is very spacious and can accommodate 9 astronauts wearing outdoor spacesuits without feeling crowded at all.

The door of the equipment cabin was slowly opened by the hydraulic manipulator, and a strong light illuminated the lunar rover and the mechanical cabin. Su Yang started the lunar rover, and the motors in the six wheels made a low sound. They

Dragging two trailers, it drove like a small train toward the desolate depths of the Moon Sea.

The terrain of the lunar mare is similar to the Gobi Desert on Earth, with endless stretches as far as the eye can see and little undulations. The lunar rover's large soft tires and efficient shock absorber system allowed the astronauts in the vehicle to feel only a slight shaking but no bumps.

Team leader Su Yang drove the lunar rover and followed the direction of the satellite navigation. He asked:

"Are you familiar with the mission briefing?"

Everyone nodded:

"Um!"

Qiu Yusheng looked at the mission briefing on the screen and frowned:

"Team leader, I saw in the briefing that our task this time is to build an equipment foundation and install equipment. Why is the name of the equipment painted in black? Is there a higher level of confidentiality for us?"

Li Linjie looked at the tablet on his arm, and it was exactly what Qiu Yusheng said. The names of the devices they wanted to install were all painted in black. Su Yang shook his head:

"If it's not a secret, why should I keep it secret from you? I painted out the name of the equipment. I will tell you after your work is completed."

"Why do you do this?" Qiu Yusheng asked puzzledly.

Su Yang still smiled naively:

"You will know after you finish assembling it."

The lunar rover drove on the desolate lunar sea for more than an hour and stopped next to an open-air unit. This unit was two stories high and the size of two basketball courts. They were connected in a row by four square units.

There is a cargo landing module parked there a few hundred meters away from the crew. It was launched directly from the earth.

Li Linjie looked back at the direction they came from. The base was not far from here. Because of the curvature of the moon's surface, the buildings of the base could no longer be seen. Only the shuttles flying frequently to and from the space station and the base could be seen.

Su Yang asked Li Linjie and three other team members to stay here to build the equipment foundation, while he took Qiu Yusheng and the other three team members to disconnect the lunar rover and the trailer and go to the distant cargo landing module to unload the equipment.

Li Linjie untied the ropes binding the machinery on the trailer, sat on a drilling machinery the size of an SUV, and drove it off the trailer.

Compared with the huge crawler drills on the earth, the ones used on the moon are much smaller. Because the moon's gravity is only 17% of the earth's, the structure responsible for bearing the mechanical weight does not need to be made so strong. This is just because of the moon's gravity.

The gravitational force is very small, and there are four anti-claw mechanical arms on the body of the drilling machine. They are used to stabilize the body when drilling to prevent the body from being pushed into the air by the reaction force of the drilling.

Li Linjie drove the drilling machine to the side of the unit according to the training process, where another team member had already marked the location to be drilled with an instrument. He controlled the drilling machine to open the anti-claw manipulator to stabilize the car body and move the spiral shape

Align the drill pipe with the marked point, and then start digging.

This is the first time for everyone to work outdoors on the real lunar surface. They are well-trained and can calmly complete these seemingly simple tasks without any error margin.

About half an hour later, the depth of the borehole had met the requirements. Li Linjie got out of the car and dragged a thigh-thick pump pipe from the trailer's pump truck and connected it to the drill rig. Then he said to a teammate through the radio:

"Get ready to pump the binder, I'm going to start mixing it into piles."

"Okay, the pump is ready. You can start stirring over there."

Li Linjie controlled the drill rod of the drill to rotate in the opposite direction, and slowly pulled out the drill rod from the lunar rock cut into small pieces by the drill bit. While pulling out, the adhesive specially made for the lunar soil started from the tip of the drill rod and moved towards the lunar soil.

Sprinkler irrigation.

When the drill rod was completely pulled out of the lunar surface, the crushed lunar rock, lunar soil, and adhesive were completely mixed together to form a foundation pile with load-bearing capacity. Everything went well, and Li Linjie breathed a sigh of relief.

It was the first meaningful work he completed on the moon. He operated the drill to the next point and said:

"Getting ready to start digging the second pile."

In Suyang, dozens of meters away, they also prepared equipment for transporting a cargo landing module. This heavy-duty cargo landing module was directly launched into the lunar orbit using a super-heavy launch vehicle on Earth and then landed here via orbital airdrop.

So it looks like the warhead of an intercontinental missile is placed here on a tripod, and there is still a landing deceleration buffer rocket in its lower part.

Su Yang used the remote control equipment on the lunar rover to first control the cargo compartment to separate the buffer rocket engine below, and then they used the traction rope on the lunar rover to pull it aside.

Then a bunch of parts were taken out from the bottom of the cargo compartment. They can be assembled into a small trailer to hold the cargo. Originally, this small trailer could be made into a hydraulic automatic folding and unfolding device. However, considering the carrying weight and the difficulty of the process, there is still a need for recycling.

Various factors were used, and finally the most primitive artificially assembled parts were made.

When Su Yang and the others assembled the small trailer, Li Linjie and the others also completed half of the foundation piles.
