A big country of aerospace with black technology

Xu Ying carefully drove the spacecraft, preparing to complete the docking work with the unmanned engineering spacecraft.

The docking interface of the unmanned engineering spacecraft was left in the initial design stage.

The idea at the time was that the docking interface would be used to dock cargo spacecraft.

Therefore, the Longguo standard docking interface is used.

Xu Ying's manned engineering spacecraft can also dock with it.

This also reflects the benefits of standardized design.

Of course, some countries have raised objections to Dragon Kingdom’s independence standards.

It is believed that this is not conducive to later international cooperation.

In response, Zhang Xingyang said on the spot: "If you are unwilling to accept the relevant standards, you can leave."

"Our star port has limited space and cannot accommodate so many people."

“Thank you for making space for others.”

At that time, many countries said that they could kick out those who did not accept it.

The construction scale of the Star Port is very large. It is expected that after the first phase of construction is completed, it will be able to accommodate more than 100 people.

Compared with the space stations built by various countries in the past, this is a very large number.

However, there are more than a hundred countries in the world.

Not only those major space powers want to board the star port.

Some regional powers also want to make a difference in the aerospace field.

Therefore, these quotas are definitely not enough.

This is based on the fact that Dragon Kingdom occupies more than half of the personnel quota.

Therefore, being able to drive away some competitors was a success that everyone present was happy to see.

The countries that raised objections did not expect that no one agreed with their statement.

But it was not good to just quit in such a dejected manner, so I could only stay where I was shamelessly.

However, anyone with a discerning eye can see it.

They have actually offended the Dragon Kingdom, and it is impossible not to see them later.

"I have started the automatic docking process and the automatic docking is in progress."

Xu Ying reported to the Tiangong Space Station and the ground command center through communication satellites.

After all, he is not a professional astronaut. Although he has learned the manual docking procedure, he is not proficient in it.

For the first time docking, it is safer to leave it to the automatic docking program.

Xu Ying looked at the giant thing outside the porthole and thought: "If someone with a phobia of giant objects comes to see it, it will definitely scare the piss out of them."

An unmanned engineering spacecraft that is only about ten meters long, dragging steel dozens of times its size, flies in the open space.

It's like an ant dragging a giant dragon flying.

It gives people a strong sense of absurdity.

The Tiangong-1 unmanned engineering spacecraft is located on the side and bottom of the entire star port frame.

The spacecraft Xu Ying is riding must first fly in front of it before the docking operation can be started.

The thrusters spit out dark blue flames, and the spacecraft slowly accelerated.

Then the attitude adjustment engine will slide the spacecraft into the flight path of the unmanned spacecraft.

Subsequently, under the control of computers on both sides, the relative speed of the two slowly decreased.

Until the two are relatively stationary.

A gentle vibration spread through the spacecraft Xu Ying was riding.

Xu Ying did not directly enter the unmanned engineering spacecraft.

Instead, I turned on the automatic inflation program and waited for a while.

The interior of the unmanned spacecraft had been filled with inert gas before.

This was done mainly to protect the high-precision equipment inside the spacecraft.

Prevent them from oxidative damage in an oxygen environment.

After all, oxygen is highly active.

After entering the unmanned spacecraft directly, Xu Ying was about to die from lack of oxygen on the spot.

After waiting for half an hour, the original inert gas inside the unmanned spacecraft was completely evacuated and a sufficient amount of mixed air was filled.

Xu Ying finally entered the unmanned engineering spacecraft.

The unmanned engineering spacecraft was designed with manned needs in mind.

Because Xu Ying was in the cabin, she could still use her body.

But inside the spacecraft, there are no supplies for human survival.

Xu Ying followed the instructions from the ground command center and first started the self-test of the measurement system of the unmanned engineering spacecraft.

The temporary propulsion system has eighteen thrusters with the same thrust.

They need to be installed on each keel.

In addition, a new control system also needed to be installed.

Used to control this very complex propulsion system.

After the self-test of the measurement system was completed, Xu Ying took out the neatly packaged control system from the cargo hold of the spacecraft she came on.

The thruster control system looks like an ordinary square box half a meter square.

But in fact its mass is more than 200 kilograms.

If it were on the surface of the earth, it would be almost impossible for Xu Ying to pick it up so easily.

That is to say, in the weightless environment of space, Xu Yingcai was able to pick it up effortlessly.

Floating through the connecting cabin of the two ships.

Xu Ying gently placed the control system host on the bulkhead of the unmanned spacecraft.

Fix the main unit on the bulkhead through the fixing buckles on the bulkhead.

From the beginning of the design of domestic spacecraft and space stations, a large number of new technologies were used.

Even on the internal bulkhead of the unmanned spacecraft, there will be no exposed wire tubes.

It is very different from the previous generation space station technology such as the International Space Station.

While reading the control system host manual, Xu Ying connected the host's data cable and power cable to the interface on the bulkhead according to the knowledge she learned on the ground.

Press the start button of the host, and then there will be a beep for the components to start working.

The host's work indicator light turns blue, indicating the self-test status after power-on.

"I have completed the installation of the control host and asked the ground command center to start testing."

After Xu Ying completed her work, she reported to the ground through a head-mounted communication device.

"The test signal has been received and the link test is about to begin. Thank you for your hard work, Comrade Xu Ying."

Geng Bo's cordial words came from the ground command center.

As deputy commander-in-chief, he is temporarily responsible for the work within the command center.

Zhang Xingyang is arguing with a large group of astronauts and scientific researchers from various countries who want to be the first batch to settle in the star port.

"It's not hard, I need some rest."

Xu Ying didn't feel too tired, but according to time, it was indeed his time to rest.

"In thirty minutes, the test will be completed and we will wake you up then."

The ground command center experienced a delay of 0.2 seconds and received the latest news.

"Understood." Xu Ying said after setting the alarm clock for herself through the smart assistant that came with the spacecraft.

Half an hour was just enough for him.

Xu Ying drank a little water first.

The spacecraft carries nearly three hundred liters of water, and Xu Ying's daily quota is thirty liters.

But that doesn't mean he can spend it freely.

For subsequent survival considerations, Xu Ying basically uses no more than ten liters of water every day.

Relieve the burden on your stomach through the portable excretion system on the spacecraft.

Xu Ying lowered the lights in the spacecraft to the lowest level, and then fixed herself to the bulkhead of the spacecraft with a fixed strap.

Closing her eyes, Xu Ying ushered in her second sleep in space.

Although it's not the first time I drifted to sleep.

But Xu Ying still couldn't enter deep sleep.

Can only enter a half-dream and half-awake state.

He felt as if he had become an unknown ghost, floating above the blue earth.

Overlooking the world.

Just when he felt himself slowly drifting away from the earth and about to reach the moon.

A gentle female voice sounded in his ears.

"It's time to wake up, it's time to wake up."

Xu Ying woke up from her light sleep without any hesitation.

First, he glanced at his watch. The time had just reached the wake-up time he had set.

According to ground time, it is now exactly 4:30 in the afternoon.

In space, it has become undesirable to determine your schedule based on sunrise and sunset.

Because in one day, you may experience dozens of sunrises and sunsets.

Therefore, you must determine your schedule according to time.

However, this situation will be much better after Xu Ying reaches geosynchronous orbit.

At this orbital altitude, they can already keep in sync with the Earth's rotation.

"Welcome back, Xu Ying."

"The self-test of the control system has been completed. Please start installing and connecting the thrusters as soon as possible."

The ground command center sent the latest work arrangements.

Xu Ying followed the ground arrangements.

First, separate your Tiangong-2 spacecraft from the Tiangong-1 spacecraft.

After the solid-state connection between the two was disconnected, Tiangong-2's thrusters flashed with a faint blue light.

Flying towards the umbrella-shaped keel on the other side.

A small Hall thruster will be installed on each keel.

Although the thrust of the Hall thruster is only 80 millinewtons.

Not even a piece of paper can be blown up on the ground.

But in space, it can push a star port frame with a mass of thousands of tons.

Because there is no interference from air resistance, friction, gravity and other factors in space.

The star port can accelerate to a frightening level with such a small force.

Xu Ying started to install the first Hall thruster through the mechanical arm on the spacecraft.

The laser rangefinder on the unmanned spacecraft is working all the time.

Allowing itself to remain relatively stationary with the Tiangong-2 driven by Xu Ying.

The relative position error between the two is at the millimeter level.

It is not easy to maintain such accuracy at such a large scale and high speed.

Xu Ying's Tiangong-2 spacecraft also has high-precision measuring equipment.

It's just that they are now measuring the matching dimensions of the keel and the Hall thruster.

The outer ring size of the Hall thruster matches the keel.

Let it fit right on the outer end of the keel.

The robotic arm securely sets the Hall thruster on the outer end of the main shaft keel.

One end of the Hall thruster is a nozzle that can eject ions, and the other end is connected to the power cord and working medium pipeline.

It's just that at this time, the power cord and working fluid pipeline are still coiled into a roll.

They will eventually be connected to the Tiangong-1 unmanned spacecraft.

There are eight keels on one side of the star port.

In one day, Xu Ying could not finish the installation.

The Hall thrusters at 4 different positions are installed.

Xu Ying has spent nearly six hours.

The installation of the Hall thruster actually did not take Xu Ying too long.

Time is mainly spent on moving the ship.

It takes a lot of time for the thruster to accelerate and decelerate.

"Report to the command center that the installation of Hall thrusters 1-4 has been completed."

"It's about to return to the Tiangong-1 unmanned spacecraft."

Xu Ying reported the report a little tiredly.

Whether it is driving a spacecraft or installing a Hall thruster, it is not an easy job.

Every second requires Xu Ying's high concentration.

There can be no mistakes.

"You can return."

After receiving the information from the command center, Xu Ying breathed a sigh of relief.

After another hour, the Tiangong-2 spacecraft finally successfully docked with Tiangong-1.

Six hours of intense concentration brought Xu Ying to a threshold both physically and mentally.

First, use the heating device in the spacecraft to heat a pack of rations.

Xu Ying looked out the window while waiting for her meal.

The moon can be seen at this time.

From a space orbit of more than 30,000 kilometers, look at this satellite that has been orbiting the earth for hundreds of millions of years.

Don't have a taste.

Because there are no atmospheric disturbances.

The moon in Xu Ying's eyes is clearer than what is seen on the earth.

He could even see the numerous craters on the moon.

In fact, at this height, Xu Ying used some observation equipment.

You can even see the Yutu lunar rover working on the moon.

Even if the lunar rover is not visible, the lunar lander covered in gold foil is still eye-catching.

Xuying ate the heated Yangzhou fried rice with a spoon.

It is said that this is fried by a special chef, but it tastes just like that in Xuying.

Just be able to provide yourself with enough energy.

After Xu Ying had eaten and washed briefly, she got into her sleeping bag and fell asleep.

On the ground, there are still a large number of people holding on for him.

For his work in space, at least more than 100 monitoring units around the world work around the clock.

There are more than 100,000 related employees.

Even in sleep state, the ground command center is still supervising through various devices.

Just in case something unexpected happens to Xu Ying during this process.

A slight fluctuation in his heart rate can alert a large group of medical experts on the ground.

"This is the latest added requirement, take a look."

Zhang Xingyang, who returned to the ground command center, handed Geng Bo a piece of paper and said.

Geng Bo looked at the thin paper in his hand, but his brows furrowed tightly.

"In terms of manufacturing technology, it's not a problem."

"But it will have serious interference with our project construction progress."

Geng Bo asked with some confusion:

"Why would you suddenly add something like this?"

"Because we're going to the moon."

Zhang Xingyang turned around and said with a relaxed expression:

"Do you think it would be easier to land on the moon directly from the ground, or launch a spacecraft from geostationary orbit?"

The plan in Geng Bo's hand states that a small electromagnetic acceleration orbit will be added to the star port.

"So this thing is used to launch the moon landing spacecraft?"

Geng Bo waved the plan in his hand.

"If we really do this, many of our construction plans will be disrupted and restarted."

"But it's worth it."

Zhang Xingyang said seriously:

"please believe me."

"I guarantee it with my honor!"
