Five Hundred and Forty-One Moon 1st (3)

Ye Han immediately asked: "When will the earth send the raw materials?"

Gao Kai, who had already put on his spacesuit, took off his helmet and held it in his hands: "The equipment that should be sent is all in place. There will be no special circumstances in the future, and we will not send raw materials and equipment to the moon. We must solve it by ourselves. Therefore, there is no absolute guarantee." If necessary, it is best not to touch the printer."

Ye Han sighed helplessly: "Understood."

He didn't know exactly how many equipments were on the moon, and he didn't know exactly what equipments there were, but there were at least hundreds of unsealed spaceships in the temporary base, and there must have been a lot of equipment, and there were even necessary backups.

Gao Kai fastened his helmet and walked towards the airlock: "Hurry up!" After he got into the airlock, the door closed tightly behind him, and there was a hissing sound of suction, and the air suction equipment quickly evacuated the air in the airlock until the representative The green indicator light for passage was on, and Gao Kai opened the outer gate and stepped on the moon.

The airlock leading from the living cabin to the outside world allows only one person to pass through at a time, and the whole group must be divided into dozens of times before they can all leave the living cabin.

It's not impossible to leave at once. The prerequisite is that everyone puts on their space suits and directly evacuates all the air in the locker room.

In this case, the control system of the living cabin allows the two gates to be opened at the same time, so that one in the dressing room counts as one, and they can all leave at once.

Speaking of this, I have to talk about the structure of the living cabin. The living cabin is not a cabin with a simple structure. Its interior design is very complicated. The airtight structure can be regarded as a single-layer airtight door.

This design can maximize the air pressure in each small space in the event of pressure loss.

Moreover, the designer even considered the opening direction of the airtight door. Where astronauts may stay for a long time, the door must open inward.

In this way, once the indoor and outdoor pressure is lost, the indoor air pressure will tightly press the door on the door frame to prevent the loss of indoor air; on the contrary, if the indoor and outdoor pressure loss forms a negative pressure environment, the airtight door will be closed by the relatively high outdoor. The air pressure is pushed open to supplement the pressure, and it can also serve as a reminder.

Of course, under normal circumstances, most of the environmental monitoring devices can detect pressure fluctuations in advance and remind astronauts to pay attention to pressure failures in time. But if you are not afraid of 10,000, you are afraid of the eventuality. This design can prevent the adverse consequences caused by equipment failure to the greatest extent. It can be said that it is the last line of defense for the living cabin.

There are many similar designs. For example, all people live in two living cabins, which is also out of safety considerations; the dressing room between the two living cabins,

It can be used as a shelter or the like in the event of a rupture in the living compartment.

Everyone left the living cabin one by one. Gao Kai and another astronaut had already driven two lunar rovers from a nearby garage.

Gao Kai waved and said, "Get in the car, go to the construction site first, and then act in groups!"

Everyone carries a load on their bodies, and they can't jump and jump like when the United States landed on the moon, but climb on the lunar rover like when they were on the earth.

The structure of the lunar rover is very simple, just an alloy chassis, a few wheels and a simple control system.

This thing is directly driven by electricity. It is far away, and it is not a problem to run for dozens of kilometers. It is the main means of transportation for astronauts on the lunar surface.

Ye Han noticed that the wheels of the lunar rover were all hollowed out in the center, similar to the hydrangeas used for lion dances, and immediately realized that these were the legendary carbon fiber wheels.

The polar craters do not see sunlight all year round, and the surface temperature is much lower than that of a moonlit night, and the lowest can even reach minus 200 degrees.

Although the surface of the moon lacks heat convection media, the temperature of objects will not be lost for no reason, but the wheels must be in contact with the ground, so the materials used must be resistant to low temperatures.

The environment in space is harsh. Aerospace materials must not only withstand low temperatures, but also high temperatures. There are not many qualified materials. The rubber family really can’t find a member suitable for use on the lunar surface.

Many people think that one of the evidences that the American moon landing is a hoax is that the Yankee's lunar rover used pneumatic rubber tires, and the company that produced this kind of wheel has never launched such a super wheel to the market, even the Yankee. This kind of wheel was only used during the moon landing. After the moon landing, the lunar rovers and Mars rovers made by the Americans all used alloy metal wheels.

If the rumors are true, everyone will doubt whether the Yankee's moon landing is true. After all, they have used the Star Wars plan to fool Maozi, and they are habitual offenders with criminal records.

The lunar rovers looked crude, but their performance was not bad at all. The two lunar rovers left the temporary camp one after the other, drove westward for more than 300 meters, and stopped at the bottom of a continuous cliff.

That's right, a cliff.

The high craters are almost perpendicular to the ground, the cliffs are uneven, and large pieces of fault rock can be seen everywhere.

Gao Kai pointed to the cliff not far away and drew an arch in the air: "The gate of the base is here."

Ye Han walked to the bottom of the cliff, his headlamp illuminated the black rock, he couldn't help but said: "It would be fun if we found fossils here."

"Then you are amazing." Gao Kai said.

The origin of the moon is still a mystery. If fossils can be found on the moon, it will prove the ancestry of the moon.

"Don't be kidding, everyone remember this place well." Gao Kai said.

Later, Gao Kai called everyone on the lunar rover, and ran to the icy lake in the south, so that everyone could remember these two most important positions, and then several groups of people officially separated.

The excavation team began to lay cables leading to the cliff, and when the cables were laid, the base would be formally excavated.

The logistics team returned to the temporary base and entered the biological experiment cabin to wait for the vegetable seedlings cultivated without soil. The experimental cabin is called Vegetable Garden.

According to the plan on the ground, when the base expands and there is enough space in the future, a batch of poultry such as laying hens will be sent over to enrich the astronauts' diet.

There is no shortage of eggs in the aerospace recipes, but they are all finished products such as marinated eggs and boiled eggs. Fresh eggs cannot withstand the tremendous pressure of the rocket when it takes off.

Not only poultry, the long-term plan on the ground even wants to send all kinds of domestic animals to the moon. After all, the giant insects are rampant on the earth today. Even if wild animals are not extinct, they are on the verge of extinction. Except for humans, they belong to humans The poultry and livestock population is the largest.

Even if humans wipe out the giant worms in the future, it is impossible for the earth's biosphere to return to the state before the worm disaster. It is said that one of the most important tasks of biological experiments in various countries is to collect and preserve the embryos and DNA of wild animals for future restoration of wild animal populations.
