A big country of aerospace with black technology

"Welcome to Tiangong Space Station."

A new batch of crew members boarded the space station, and as the commander, Wu Yuan warmly greeted the new colleagues.

This was the first time she truly experienced a weightless environment, and Xu Ying felt a little uncomfortable.

A little disgusting.

Wu Yuan's enthusiasm made the three people who had just entered space a little overwhelmed.

In less than three minutes after entering the space station, they were already warned about twenty or thirty precautions in their ears.

But this also allows everyone to temporarily forget about physical discomfort.

"Let's take a photo first."

Before Xu Ying could write down what she just said.

Wu Yuan pulled everyone together again and prepared to take the first group photo.

Six people wearing navy blue uniforms were suspended in the space station.

Although my body felt a little uncomfortable, it was an unprecedented experience of being weightless.

Xu Ying still feels very magical.

Looking at the camera, they all smiled.

Just the reasons are different.

The astronauts of the fifth batch of crew have been in space for less than half a year.

Even though I felt novel about the space environment at first, it took more than five months.

This novelty has long since passed.

At this time, they miss the feeling of being down-to-earth.

This feeling is even far greater than that of submariners in the deep sea.

Now there is a new crew to take over their duties.

The day to go home is not far away.

This feeling is like waiting for a holiday on a Friday afternoon.

As for the astronauts in the sixth batch of crew, they are just like the fifth batch of crew five months ago.

They are still in the fresh stage of working on the space station.

"In the past few days, we will familiarize everyone with the various tasks of the space station."

After taking the photo, Wu Yuan said to the sixth batch of crew members.

The commander of the sixth batch of crew members is Nie Haisheng.

This is his second time in space.

Getting used to it was much better than Xu Ying's first time in space.

"Sorry to trouble you." Nie Haisheng said politely.

"Haha, we will actually feel a lot more relaxed now that you guys are here."

Wu Yuan smiled heartily and said.

He was among the second batch to be selected into the astronaut corps, so he was actually Nie Haisheng's descendant.

After some polite remarks, Nie Haisheng said:

"This time, we only have two people who can carry out construction and scientific research tasks."

"So your return time will be pushed back by more than half a month."

The sixth batch of members is very special in itself.

Except for Nie Haisheng, who is a professional astronaut, the remaining two people are not professional astronauts.

Xu Ying is a construction engineer by background, not to mention aerospace engineering before that.

The only way to connect with aerospace is by plane.

There is only one person left, the payload expert-Zhu Haichao.

"His mission is more dangerous than our previous missions."

Wu Yuan also knew from the command center the reason for their delay in returning to Earth.

But there was no resentment over it.

There are too many unexpected situations in space missions.

Just delaying their return to Earth for a few days is nothing to them.

In comparison, Xu Ying's task is actually more difficult.

A single person pilots an engineering spacecraft to perform star port construction tasks.

"Do you feel nervous?"

Wu Yuan skillfully floated to Xu Ying's side and asked.

"This task can only be completed by you alone, in case something unexpected happens."

Wu Yuan didn't finish speaking, but his meaning was expressed very clearly.

If there was an accident in space, he might not even be able to return to the ground with his body.

"I'm ready to die."

Xu Ying's reaction was unexpectedly calm, as if she had put life and death aside.

But looking into his eyes, one could tell that Xu Ying was still a little panicked.

Just try not to show it.

To celebrate everyone's successful reunion in space.

Not much work went on during the day.

Instead, he took out most of the fresh vegetables and fruits, as well as various meats brought from the earth, and made a big meal.

"This is the lettuce we grew ourselves, try it."

Wu Yuan enthusiastically served the new astronauts food.

The idea of ​​a space farm is undergoing various detailed experiments within the space station.

The growth cycle of vegetables grown without water is even shorter than on earth.

Because of the environment of the space station, there are no pests or diseases that can be seen on the ground.

Of course, this also brings trouble to the cultivation of some vegetables.

Manual pollination of vegetables is required.

“It tastes pretty good.”

After Xu Ying took a bite, she swallowed a water ball and said.

Because liquids in space are weightless, they will not fall to the ground, but will float directly in the air.

Without the influence of external forces, water will naturally maintain a spherical state to maintain its own balance.

Watch Xu Ying happily playing with water balloons.

Wu Yuan suddenly felt a bit of teasing mentality, so he raised his eyebrows and said:

"How does our drinking water taste like?"

Xu Ying felt a little strange, but she still said seriously:

"It tastes good, a little sweet."

"Then do you know where this water comes from?" Wu Yuan said with a bad smile.

Xu Ying's mind was spinning rapidly, and he had a bad premonition.

"not"

Wu Yuan still smiled and said, "Yes, it's what you think."

"This is recycled water~"

Although the space station will receive supplies every half a month.

But most of them are to replenish the space station's fuel, oxygen, parts, etc.

Only a small part is the living supplies for the astronauts.

There is even less food and water.

Therefore, the water in the space station is basically recycled water.

To put it simply, the waste liquid generated by all activities will be collected, filtered through layers, and then drank by the astronauts.

Waste fluids include sweat, urine, etc.

Xu Ying almost couldn't hold back and squirted out, but she still held back at the last moment.

With some difficulty, he moved the muscles in his throat to swallow the water ball into his stomach.

Zhu Haichao on the side also looked at the drinking water in his hand with a look of embarrassment.

Nie Haisheng, who had already been into space once, did not change his expression.

Then he picked up the water glass at hand and took a sip.

"He lied to you. What we are drinking now is the water we just brought."

"Real recycled water has no taste at all."

Wu Yuan was able to deceive two newcomers who had just entered space, but Nie Haisheng, who had already been in space twice, was not fooled at all.

After hearing Nie Haisheng's words, the two people on the side breathed a sigh of relief.

"But inside the space station, most of it should be recycled water now."

Nie Haisheng looked at Wu Yuan and said.

"It's true that our water consumption is about the same."

Wu Yuan raised a small water balloon and said:

"We've been drinking recycled water for almost a month."

"If you hadn't come here, we wouldn't be able to drink such good water."

The dinner ended with a brief introduction to the facilities of the space station.

Everyone began to take turns to rest.

Despite her excitement, Xu Ying forced herself to rest for six hours.

After washing up with a sense of novelty, Xu Ying found that Wu Yuan and Nie Haisheng had already started working.

"Let's eat something first."

Wu Yuan handed over a piece of bread.

Xu Ying put it into her mouth and drank a few more water.

After a simple meal, Xu Ying was ready to start working for the first time.

Xu Ying's job is very simple, that is, to drive the engineering spacecraft and complete the construction of the star port.

However, this work is also dangerous.

Because the star port has not yet installed an energy core or a propulsion system.

Only the unmanned engineering spacecraft pulling it can keep its orbit normal.

As long as one component flies out of the high-speed star port, it can crash the engineering spacecraft driven by Xu Ying.

"Be careful, and if it doesn't work, activate the emergency escape system."

When Xu Ying entered the transfer module of the engineering spacecraft temporarily connected to the space station, Nie Haisheng said with concern.

Unlike others, Xu Ying had to stay alone on the construction ship for nearly ten days.

After completing many heavy and complicated construction tasks, you can return to the space station for a short rest.

After all, the height of the star port is much higher than their current location.

A trip requires a lot of fuel supplies.

Therefore, there are a lot of tasks to complete every time you go.

"I'll keep an eye on it, thank you."

Xu Ying smiled and then got into the engineering spacecraft without looking back.

The engineering spacecraft is already fully loaded with fuel and various construction tools.

And a large number of high-precision thrusters.

Xu Ying's most important job this time is to install a temporary propulsion system for the star port.

Originally, the star port did not have a plan for a temporary propulsion system.

According to the design plan, the star port will directly adopt an electric propulsion system after installing the nuclear reactor.

However, many countries that are investing money believe that the current construction plan is too extensive.

Zhang Xingyang can actually understand their thoughts.

They were simply afraid that the country would use the excuse of power failure of the unmanned spacecraft and then directly smash the starport on top of their heads.

The mass is thousands of tons, and the speed can reach a kinetic energy strike close to the first cosmic speed.

Everyone who saw it was frightened.

Therefore, they strongly requested that the country add a temporary propulsion system to the star port.

Ease their sense of crisis.

They are even willing to pay a lot of money for it.

For example, the garrison rights of several important ports and the trade of military equipment.

Or send money directly.

After Xu Ying entered the engineering spacecraft, she did not immediately disconnect from the space station.

Instead, he checked the quantity of various materials in the spacecraft.

Especially oxygen, water, food, etc. that are related to your own survival.

The most important of these is oxygen.

He could survive for several days without water and food.

He couldn't survive even five minutes without oxygen.

Then check the operating status of various equipment.

After ensuring that there were no problems, Xu Ying reported to the space station and ground command center.

"The Tiangong-2 engineering spacecraft is ready for separation."

"Separation request received."

"Separation request approved."

Whether inside the space station or in the ground command center.

Countless people were sweating at this moment for Xu Ying who was alone in the spaceship.

But Xu Ying was not too nervous.

Very skillfully, he started the automatic separation process of the engineering spacecraft.

Then there's the waiting.

After receiving the program, the first thing to work is the attitude engine of the Tiangong Space Station.

Complete the adjustment of your own posture.

Then the Tiangong-2 spacecraft detached from the rear of the space station and started its own engine.

Complete the separation from the space station.

Xu Ying, who fixed herself on the seat, only felt the spacecraft move slightly.

After confirming that it has maintained a certain distance from the space station through the observation equipment.

Xu Ying started the autopilot program of the spacecraft.

Started to fly towards the orbital altitude of the star port.

The attitude engine first adjusts the orbit of the spacecraft.

Let the spacecraft enter an elliptical orbit with the Earth as the focus.

Then the propulsion engine started, spitting out light blue flames.

When it reaches the highest point, the attitude engine adjusts its orbit again and enters a higher-level orbit.

Rely on this to constantly shift your own orbit.

The engineering spacecraft is getting away from the earth little by little.

Xu Ying looked down from the porthole and could already see the entire earth clearly.

It is still difficult to have a panoramic view of the earth from inside the space station.

Because the orbit of the space station is only 400 kilometers high, and the diameter of the earth itself is close to 13,000 kilometers.

The distance is too close and it is impossible to see the entire earth.

Xu Ying's current altitude is more than 10,000 kilometers, and he can see half of the earth clearly.

After more than ten hours of orbital transfer, Xu Ying finally reached the geosynchronous orbit altitude.

"Looking at the earth like this, it's quite beautiful."

Xu Ying lay near the porthole and looked at the earth in the distance and said.

People often say that only when you leave your hometown can you keep thinking about the goodness of your hometown, and only after you leave your motherland can you understand the goodness of the motherland.

Xu Ying also feels that it is only after leaving the earth that you will find that this inconspicuous planet in the universe is so beautiful.

After sighing with emotion, Xu Ying first reported to the ground command center that she had reached the predetermined orbit.

After getting the location of the unmanned engineering spacecraft and star port.

After Xu Ying imported the data into the computer, the autonomous driving system began to adjust its speed.

Waiting for a few hours for the spacecraft to rendezvous with the starport.

Although she flew for more than ten hours, Xu Ying did not feel sleepy.

Even a little energetic.

I ate a pack of self-heating rations carried on the spaceship.

Xu Ying started to use a tablet computer to record and write a diary.

He's going to be alone in space for about ten days if he doesn't do something.

Xuying felt like she might go crazy.

[July 11, 2007, weather]

Xu Ying originally wanted to write it like on the earth, but found that she didn't know how to write weather.

So I glanced at the earth below the porthole, and saw patches of white clouds on the blue surface.

"This should be considered a cloudy day."

[July 11, 2007, the weather was cloudy]

[Today is my second day in space, and the nearest human being to me is now nearly 35,500 kilometers away. 】

[If you want to choose the loneliest person in the world, then I will definitely vote for myself. 】

[I can already see the star port in the distance, it is really big! 】

[Compared with it, what I am sitting on now is like a small sampan! 】

Xu Ying closed her tablet and looked at the star port in the distance.

It is like a skyscraper erected in front of your eyes!
