The transport spacecraft circled the moon for a total of four large circles before slowly adjusting its orbital position and officially docking with the space port.

The difficulty of this technology is not too great, and it is similar to the docking of a space station. It is divided into four stages: remote guidance, short-range guidance, and final approach and docking.

After so many years of development, the technology has become quite mature.

"Astronauts, please note that the spacecraft is about to arrive at the station. Please put on your space suit, enter the vacuum compartment, and line up to get off the spacecraft in sequence."

Zhang Yuan exhaled and wore a heavy nano-silver ion radiation-proof suit. This protective suit looked like a thick cotton jacket. He wore a thick glass cover on his head. After the inspection, he followed him into the vacuum compartment and then got into a rail train.

"I've floated up, help me!" A male voice rang out from his headphones behind him.

Since there was no air, I couldn't even do the "swimming" action, so I could only grab the handrail and move forward.

If there is no place to leverage the power everywhere and no one can help, it may float in mid-air permanently.

There was such a horrible accident, and the unfortunate man floated in the space like this, and he was powerless to borrow. The nearest handrail was only one meter away from him, but no matter what, he could not move a little. By the time the rescue team arrived, the guy had completely collapsed.

So nowadays, spacesuits have a very small jet device that can inject airflow to avoid this phenomenon. Of course, this function is not used or not. Any little material in the universe is precious.

Zhang Yuan pulled the handrail and slowly pulled him down.

This guy kept saying "thank you".

This is the largest spaceport of mankind, "Lanmen 7". All astronauts will enter the huge annular centrifugal force zone along the central axis of "Earth Age".

Not only the air can spread sound, but any substance can spread sound. The roar of the rail train is transmitted to the ears through the handrails on the hand, and there is a very tough rumble feeling.

The Earth Age is the most proud work of the "Wild Wolf Design Bureau".

Zhang Yuan's father was once one of the main designers of the Wild Wolf Design Bureau.

Essentially, it can be regarded as a super-large "balloon".

Except for important structures such as the spacecraft's central axis and engine chamber, which use high-strength metal, most of the other parts, including the ship's walls, light sails, etc., are very light nano-flexible materials.

The universe is almost in a vacuum state, with a pressure of almost 0, but the spacecraft is filled with air. According to the standard atmospheric pressure, the air pressure is 1.01×10^5    Pa.

The pressure difference between inside and outside is equivalent to the pressure of ten tons of material per square meter under the gravity of the earth, which makes the entire spacecraft expand spontaneously to the outside to maintain the designed shape.

The advantage of this is that the spacecraft is very, very light and fully utilizes the super tensile resistance of the nanomaterial itself.

Although the spacecraft is huge and like a mountain, its weight is less than 800,000 tons.

Two girls were whispering in their headphones, but they accidentally opened a small public channel.

"It is said that the nanomaterial on the wall of the spacecraft is only 4 mm thick... It looks so unsafe. What if it breaks suddenly?"

"How could it be broken? That's a nanomaterial. It was originally expected that 1 mm would be enough, but for safety reasons, it thickened four times."

Listening to their conversation, I probably haven’t interned in the Space City and are a group of newcomers.

Li Zhendong turned around and explained with a smile: "The spacecraft wall is a mixed structure of nanomaterials and aerogels. Just like steel cement, the nanomaterials are only 4 mm thick, but there is also aerogel that is lighter than air as a load-bearing structure, so it adds more than this thickness."

"The spacecraft structure is not what you imagined. The gravity-free area has no atmosphere, and it stores various material resources. Only the circular living area has atmosphere. It has a honeycomb structure inside, which is divided into many small rooms, and the outermost area is not inhabited by people."

"Every room has a pressure sensor. If there is an accident on the outside, it will be difficult to immediately affect the inside. Don't worry, we will go and repair it immediately!"

"Are you a spaceship maintenance worker?" The girl widened her eyes and turned her head.

She introduced herself very enthusiastically: "Hello, my name is Li Yiyi, I am a kindergarten teacher, or a...haha, painter."

"My name is Li Zhendong, everyone's surname is Li, and they are the same ancestor as you!"

"Is that true, haha!"

"We are all descendants of me."

"I?"

"Li Er!"

"oh!"

Seeing Li Zhendong teasing girls again and talking about quite boring topics, Zhang Yuan instinctively felt a little embarrassed for him. Can you talk about some normal topics, it seems that it is very culturally meaningful.

As for what kind of spaceship maintenance personnel, I was thinking too much... Ye Kaifu's skilled technician is the real spaceship maintenance personnel.

Although they have some skills, they still don’t know how to encounter real difficulties.

"You are... Zhang Yuan! You are actually an astronaut!"

Zhang Yuan’s bag, hey, am I so famous? What’s the situation…

A group of girls chattered around Zhang Yuan again.

Li Zhendong spread his hands and was stolen from the limelight, which was quite helpless.

The reason for the strange job of "kindergarten teachers" is that 500,000 young people will inevitably have the possibility of accidental fire. In the spacecraft, everyone is encouraged to take contraceptive measures when they are passionate, but they will not have to have a forced abortion. If they are pregnant, they will have to give birth.

In short, with the support of various high-tech, the first basic goal of a small society is to be self-sufficiency and maintain the entire social form; the second goal is development.

While talking like this, the rail train turned a corner and slowly stopped.

Everyone swam into a large elevator again.

This elevator will lead from the central axis of the spacecraft to the bottom of the centrifugal wheel, and at the same time give all passengers a certain lateral linear speed.

"Earth Age" uses centrifugal force to simulate gravity equivalently. The radius of the centrifugal wheel of 2 kilometers, and the bottom wants to generate gravity similar to the earth, the angular velocity is about 0.071rad/s, which is equivalent to a rotation of 89 seconds.

Such an angular velocity is not high, which means that Coriolis' strength is very small and that humans are very comfortable living inside.

"Drip", the elevator door finally opened, everyone entered a small room and took off their space suits.

The temperature is 24 degrees Celsius and the air humidity is 50%.

Zhang Yuan stepped on the floor excitedly. The texture under his feet was a bit similar to that of the carpet, but it did not lose its hardness.

Moreover, it has gravity similar to the earth, which is very convenient to move.
