Wandering Spaceship in Deep Space Chapter 54: Super large “balloon”

　　The transport spacecraft orbited the moon 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, and 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.

　　"Attention, astronauts, the spacecraft is about to arrive at the station. Please put on your spacesuit, enter the vacuum chamber, and line up to get off the spacecraft."

　　 Zhang Yuan exhaled and put on a heavy nano-silver ion radiation-proof suit, which looked like a thick padded jacket. Wearing a thick glass cover on his head, after the inspection, he "swimmed" 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 permanently floating in mid-air.

　　 once such a horrible accident happened, this unfortunate person just floated in the space like this, there was nothing 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 bit of matter in the universe is precious.

　　 Zhang Yuan pulled the handrail, and slowly pulled him down.

　　 This guy repeatedly said "Thank you."

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

　　 is not only air that can transmit sound, but any substance can transmit sound. The roar of rail trains is transmitted to the ears through the handrails, and there is a very strong rumbling feeling.

　　Earth Times 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 very large "balloon".

　　 Except for the use of high-strength metal for important structures such as the spacecraft’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 spacecraft is full of air. According to the standard atmospheric pressure, the pressure is 1.01×10^5Pa.

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

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

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

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

　　 "It is said that the nano material of the spacecraft wall is only 4 mm thick... It looks so unsafe, what if it breaks suddenly?"

　　"How could it break? That's nanomaterials. It was expected that 1mm would be enough, but for safety reasons, the thickness has increased by four times."

　　Listening to their conversations, they shouldn’t have practiced in Space City. They are a group of newcomers.

　　 Li Zhendong turned his head and explained with a smile: "The spacecraft wall is a hybrid structure of nanomaterials and aerogels. Just like reinforced concrete, nanomaterials are only 4mm thick, but there is air lighter than air. Gel acts as a load-bearing structure, so it adds up to more than this thickness."

　　"The structure of the spacecraft is not what you think. There is no atmosphere in the gravity-free zone, which stores all kinds of material resources. Only the annular living area has the atmosphere. Inside is the honeycomb structure, which is divided into many small rooms, the outermost one. The place is uninhabitable."

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

　　 "Are you a spacecraft 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 you are the same ancestor!"

　　 "Really, haha!"

　　 "We are all descendants of Lao Tzu."

　　"I?"

　　 "Li Er!"

　　 "Oh!"

　　 Seeing Li Zhendong teasing his sister again and 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 spacecraft maintenance personnel, I just think too much... Ye Kaifu's skilled craftsmen are the real spacecraft maintenance personnel.

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

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

　　 Zhang Yuan’s head bag~IndoMTL.com~Hey, am I so famous already? What's the situation...

　　 A group of girls whirled around Zhang Yuan again.

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

　　 The strange job of "kindergarten teacher" is because half a million young people will inevitably have the possibility of wiping out their guns. Inside the spacecraft, everyone is encouraged to take contraceptive measures when they are passionate, but they will not force an abortion. If they are pregnant, they can only give birth.

　　 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.

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

　　Everyone swam into a large elevator again.

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

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

　　The angular velocity is not high, which means that the Coriolis force is very small, and humans live in it very comfortably.

　　"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 the earth, which makes it easy to move.

　　 It’s just that I’ve been in a weightless state these days, my body is a bit broken, and it’s a bit hard to walk for a while.
