Deep Space Fleet

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

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

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

"Attention astronauts, the spaceship is about to arrive. Please put on your spacesuit, enter the vacuum chamber, and line up to get off the spaceship one by one."

Zhang Yuan exhaled, and put on the heavy nano-silver ion anti-radiation suit, which looked like a thick padded jacket. Wearing a thick glass cover on his head, after the inspection, he followed "swim" into the vacuum chamber, and then got into a rail train.

"I'm floating up, help me!" A male voice sounded from the earphone behind him.

Due to the lack of air, I couldn't even do the "swimming" movement, so I could only grab the handrail and move forward.

If there is no place to borrow power around, and no one to help, it may be permanently floating in mid-air.

There have been such horrible accidents, and this unfortunate person was just floating in the space, powerless. The nearest handrail was only one meter away from him, but no matter what, there was no way to move the slightest bit. By the time the rescue team arrived, the guy had completely collapsed.

Therefore, the current spacesuits all have a very small jet device that can jet airflow to avoid this phenomenon. Of course, whether this function can be used or not, every bit of matter in the universe is precious.

Zhang Yuan pulled the armrest and slowly pulled him down.

The guy even said "thank you".

This is the largest human spaceport "Longmen 7". All astronauts will enter the huge ring-shaped centrifugal force zone along the central axis of "Earth Times".

Not only air can transmit sound, but any substance can transmit sound. The roar of rail trains is transmitted to the ears through the armrests on the hands, and there is a very tough rumbling feeling.

The Earth Times 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 seen as an oversized "balloon".

Except for the high-strength metal used in important structures such as the central axis and engine room of the spacecraft, most of the rest, including the ship walls, light sails, etc., are made of very lightweight nano-flexible materials.

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

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

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

Regardless of the huge size of the spaceship, it is like a mountain, but its own weight is less than 800,000 tons.

There were two girls in front of them whispering in the earphones, but they inadvertently opened a small-scale public channel.

"It is said that the nanomaterials on the walls of the spaceship are only 4mm thick...it looks so unsafe, what if it suddenly breaks?"

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

Listening to their conversation, they should not have practiced in the space city, they are a group of newcomers.

Li Zhendong turned around and explained with a smile: "The spaceship wall is a mixed structure of nanomaterials and airgel. Just like reinforced concrete, nanomaterials are only 4 mm thick, but there is also airgel, which is lighter than air. Load-bearing structure, so it adds up to more than this thickness.”

"The structure of the spaceship is not what you imagined. There is no atmosphere in the gravity-free area, and various material resources are stored. Only the ring-shaped living area has an atmosphere. The inside is a honeycomb structure, which is divided into many small rooms. The outermost place is not living."

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

"Are you a spaceship maintenance personnel?" The girl turned her head with her eyes wide open.

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

"My name is Li Zhendong. Everyone's surname is Li. I have the same ancestor as you!"

"really? Haha!"

"We are all descendants of Lao Tzu."

"I?"

"Li Er!"

"oh!"

Seeing Li Zhendong flirting with girls again, and talking about rather boring topics, Zhang Yuan instinctively felt a little embarrassed for him. Can you talk about some normal topics, making it seem very culturally meaningful.

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

Although they have a little technology, they still don't know how to encounter real problems.

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

Zhang Yuan has a bag on his head, hey, am I already so famous? what's the situation……

A group of girls chattered around Zhang Yuan again.

Li Zhendong spread his hands, feeling a little helpless after being robbed of the limelight.

The reason why there is such a strange job as "kindergarten teacher" is that half a million young people will inevitably have the possibility of misfire. Inside the spaceship, everyone is encouraged to take contraceptive measures when they are passionate, but abortion will not be forced. If you are pregnant, you can only give birth.

In short, with the support of various high-tech, the first basic goal of a small society is to be self-sufficient 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 center axis of the spaceship to the bottom of the centrifugal wheel, and at the same time give all passengers a certain lateral linear velocity.

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

This kind of angular velocity is not high, which means that the Coriolis force is very small, and it is very comfortable for human beings to live in it.

"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 stomped on the floor excitedly. The texture under his feet was similar to that of a carpet, but without losing its hardness.

Moreover, it has a gravity similar to that of the earth, so it is very convenient to move.

It's just that, being in a state of weightlessness for the past few days, my body's bones are a little falling apart, and it's a little difficult to walk for a while.
