Deep Space Planet Leader

The transportation spaceship circled the moon in a total of four large circles before slowly adjusting its orbital position and officially docking with the space port.

This technology is not too difficult. It is similar to the docking of the space station. It is divided into four stages: long-range guidance, short-range guidance, final approach, and docking.

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

"Astronauts, please note that the spaceship is about to arrive. Please put on your spacesuit, enter the vacuum chamber, and line up for the spaceship."

Zhang Yuan exhales one breath saying , Put on heavy nano-silver ion radiation protective clothing, this kind of protective clothing looks like a thick cotton 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!" A male voice rang from the headset behind him.

Because there is no air, I can't even do the "swimming" action, so I can only move forward with the armrest.

If there is no place to borrow, and no one can help, it may be floating in midair permanently.

There has been such a horrible accident before, and this unfortunate person just floated in the space, unable to borrow. The nearest handrail was only one meter away from him, but in any case, there was no way to move a bit. When the rescue team arrived, this guy had completely collapsed.

So today's spacesuits have a very small jet device that can jet airflow to avoid this phenomenon. Of course, whether this function can be used or not, any matter in the universe is precious.

Zhang Yuan pulled the handrail and slowly pulled him down.

This guy even called "many thanks."

This is the largest spaceport of mankind "Dragon Sect 7". All astronauts will enter the huge circular centrifugal force zone along the central axis of "Earth Era".

Not only air can propagate sound, but any substance can propagate sound. The rumbling sound of rail trains is transmitted to the ears through the handrails, giving a very strong hong long long feeling. .

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

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

In essence, it can be seen as a super-large "balloon".

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

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

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

The advantage of this is that spaceship is very, very light, and it fully utilizes the super tensile strength of the nanomaterial itself.

Don't look at the huge volume of spaceship, like a mountain, but its weight is less than 800,000 tons.

There are two girls in front of them whispering in the headset, but they accidentally opened a small public channel.

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

"How could it break? It’s a nano material. It was expected that 1 millimeter would be enough, but for safety reasons, it’s four times thicker."

Listening to their conversations, I should have never practiced in Space City, yes. A group of newcomers.

Li Zhendong turned around and explained with a smile: "The spaceship wall is a hybrid structure of nanomaterials and aerogels. Just like reinforced cement, nanomaterials are only 4mm thick, but they are more A light aerogel is also used as a load-bearing structure, so it adds up to more than this thickness."

"The spaceship structure is not what you think. There is no atmosphere in the gravity-free zone, which stores various material resources. Only the ring There is atmosphere in the living area. The honeycomb structure is divided into many small rooms. The outermost part is not inhabitable."

"Every room has an air pressure sensor. If the periphery is really There is an accident in some place, and it is difficult to immediately affect it. Don't worry, we will repair it immediately!"

"Are you a spaceship maintainer?" 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 you are the same ancestor!"

"Really, haha!"

"We are all descendants of Laozi."

"I?"

"Ah Li Er!"

"Oh!"

I saw Li Zhendong teasing his sister again, and at Talking about rather boring topics, Zhang Yuan instinctively felt a little embarrassed for him. Can you talk about a more normal topic, which seems to be culturally meaningful.

As for the spaceship maintainers, I think too much... Ye Kaifu's skilled craftsmen are the real spaceship maintainers.

Although they have a little technology, they still won’t encounter real problems.

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

Zhang Yuan is a head bag, hey, am I so famous already? What's the situation...

A group of girls chirp chirp twitter twitter again whirled around Zhang Yuan.

Li Zhendong spread his hands and was robbed of the limelight, quite helpless.

The reason why there is such a strange job as a "kindergarten teacher" is because 500,000 youngsters will inevitably have the possibility of wiping out their guns. In spaceship, everyone is encouraged to take contraceptive measures when they are passionate, but they will not force abortion, and they can only give birth to pregnancy.

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

As we talked, the rail train turned a bend and stopped slowly.

Everyone swam into a large elevator again.

This elevator will go from the position of the spaceship's central axis to the bottom of the centrifugal wheel, and at the same time give all passengers a certain lateral linear speed.

"Earth Era" 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 Earth. The angular velocity is about 0.071rads, equivalent to one revolution in 89 seconds. .

Such angular velocity is not high, which means that the Coriolis force is very small and humans are very comfortable living in it.

"Di", the elevator door finally opened, everyone entered a small room and took off their spacesuits.

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 the carpet, but without losing the hardness.

Moreover, it has a gravity similar to that of Earth, which makes it easy to move.

It's just that, the past few days was in a state of weightlessness, and the body was a little broken. For a while, it was a bit hard to walk.
