A big country of aerospace with black technology

The thick rocket is built on the launch site.

A new round of astronauts preparing to go into space are having a farewell party before boarding.

I already have experience in manned spaceflight, so I feel more relaxed about many tasks this time.

Zhang Xingyang sat in the audience and clapped vigorously.

This manned mission requires more space missions than the first.

Because the next manned mission will most likely involve the launch of a temporary space station core module.

Young and excited young people handed the flowers in their hands to the two astronauts who were about to go into space.

In this manned space mission, the people who are about to go into space are Fei Junlong and Nie Haisheng.

"Thanks."

After receiving the flowers, the two reported to the command center that they were ready for the space mission.

Under the watch of everyone, the two boarded the vehicle heading to the launch tower.

After that, take the elevator of the launch tower and rise to a height of tens of meters.

The two of them were now wearing neat spacesuits and could use mechanical assistance.

Therefore, compared with engineers who have to rely on their own physical strength, it is easier to enter the rocket.

After entering the orbital module, the two sat quietly in the special space seats.

Skillfully connect the various interfaces on his space suit to the spacecraft.

Connected to the communication system of the command system.

After reporting its status, the spacecraft entered the final inspection stage.

Thirty minutes later, all preparations were completed at the launch site.

Quietly waiting for the launch moment to arrive.

At nine o'clock in the morning, the scheduled launch time arrived.

Following an order from the commander-in-chief, one of the most powerful propulsion devices in human history sprayed red and blue flames.

Tens of thousands of liters of fuel per second undergo violent chemical reactions in the combustion chamber, producing more turbulent high-temperature and high-pressure gas.

Pushing itself, struggling hard to escape the shackles of the planet's gravity.

For these two astronauts, tens of thousands of staff at dozens of monitoring stations around the world, several survey ships on the ocean, and thousands of staff took action.

Ensure the smooth progress of the launch mission.

120 seconds after launch, the escape tower located at the tip of the rocket used to escape during the early stages of launch was thrown away.

160 seconds after launch, the first and second stages of the rocket successfully separated. The first stage rocket fell into the deep sea and the rocket had flown to the edge of the atmosphere.

In the command center, everyone is busy nervously.

Prepare for a call between heaven and earth.

In the early stages of launch, due to various interference factors, the communication signal on the spacecraft was disconnected from the ground command center.

This time for manned space launch, the situation is even better.

After all, astronauts are two people and can chat with each other to relieve psychological pressure.

During the first launch, there was only one person, so the psychological pressure on the astronauts was even greater.

"How does it feel to ride a rocket for the first time?" Fei Junlong, who felt that the rocket under his butt was becoming more and more stable, said to Nie Haisheng beside him.

Nie Haisheng smiled and said: "It's better than ever!"

Although they have also conducted acceleration training during ground training in the past, they are already familiar with this overload state.

However, the overload that the instrument can simulate is actually more stable.

It's not as strong as the push on the back when a rocket takes off.

When it first takes off, the rocket's overload can even reach 9 G.

Almost reaching the limit of human beings.

If the spacesuits they wore could not reduce the pressure on the body to a great extent, they would have suffered from insufficient oxygen supply to the brain and fainted.

At 9:12, a smooth communication link was finally established between heaven and earth.

The command center can learn about the physical condition of the astronauts from the radio waves.

After learning that the astronauts were in good health, everyone breathed a sigh of relief.

At this time, the spacecraft has not reached the predetermined altitude.

At 9:17, the rocket reached an altitude of about 200 kilometers, and the ship and arrow separated successfully.

The spacecraft began to rely on its own power to fly above the earth's low-Earth orbit, and at the same time, it continued to raise its altitude in circles of elliptical orbits.

At 9:29, the spacecraft entered the predetermined orbit.

Fei Junlong looked at the almost dark space outside the ship's porthole and was amazed by the beauty of space.

After admiring it for a short while, the two began their first job.

This time, the spacecraft used a life cycle system for the first time, allowing astronauts to no longer wear spacesuits with life-support devices when in the cabin.

In the cabin, you only need to wear ordinary clothes to move around.

Of course, even ordinary clothes are actually extraordinary.

Ordinary plush clothing is actually not suitable in space.

Because this kind of clothes, no matter how well made, will still shed hair.

And these tiny plushs may cause various problems due to air circulation.

The two spacesuits helped each other complete the change.

Nearly an hour had passed just to change clothes.

During this process, the spacecraft continued to increase its altitude, reaching an altitude of 320 kilometers.

"It's time for us to eat next."

Nie Haisheng asked.

"According to the schedule, it's like this." Fei Junlong looked at the small display screen on his arm and said.

Compared with the first space mission, this space mission has a lot more content.

For example, the project of experimenting with eating in space.

Last time, although Yang Hongwei also ate in space, because he had been wearing a space suit at the time, the food was relatively simple to eat and was fed directly to his mouth.

But even so, Yang Hongwei ate a lot at that time.

For example, eight-treasure rice, kung pao chicken, and even a few small moon cakes because it was the Mid-Autumn Festival!

As for this time, the two of them were floating in the cabin and eating without any assistance.

Of course, their conditions are different from Yang Hongwei, who eats ready-to-eat food, that is, cold rice. They have food heating devices.

Finally, you can have a hot meal in space!

Of course, even so, eating is something I don't agree with.

Because in space, the influence of gravity is weak.

So when they eat, they need to tie the dinner plate to their legs or fix it somewhere before they can eat.

When they were at the ground base, they spent a lot of time training themselves how to eat.

Fei Junlong used a pair of special scissors to cut open the heated lunch box, scooped up a spoonful of fried rice and stuffed it into his mouth.

Although the taste of food is no different from what you eat on the ground, eating in an environment like space is quite interesting.

Nie Haisheng on the side has already begun to eat the dessert, freeze-dried ice cream.

Drinking water is also interesting compared to the ground.

Nie Haisheng took a bite of the freeze-dried ice cream and took a sip from the water ball floating in front of him. The small water ball floated into his mouth.

Because in space, it is not affected much by gravity, so the water ball is almost a standard circle.

After Nie Haisheng finished eating, he looked at Fei Junlong who had not yet finished eating. He took the camera on the bulkhead and started filming the scene of eating in space.

Inside the spacecraft, the residue produced by eating must also be absorbed with a special air duct to avoid various floating objects in the cabin.

After eating, the two took a short rest.

After all, the two of them had almost no time to rest since nine o'clock in the morning.

Lunch took almost an hour.

Resting in space is not that simple.

Although the human spine will be more comfortable because it is out of the gravity environment, another problem will arise.

That is, when resting, if it moves slightly, it will float continuously in the cabin.

So both of them got into the specially made sleeping bags, which were locked to the bulkhead with ropes and fixed hooks.

This way, you don’t have to worry about people sleeping and their bodies floating around in the cabin.

After the break, it was already around three in the afternoon.

After exercising their bodies for a while, the two began their busy work.

The first thing to be done is the on-orbit interference force test.

It sounds like it's actually relatively simple.

That is, to verify the interference of astronauts on the attitude of the spacecraft when passing through various cabins of the spacecraft.

As we all know, the effects of forces are reciprocal.

When astronauts pass between two different cabins, they will inevitably use some force to support themselves.

And this force has a reaction force on the spacecraft.

In space, because there is no air friction, a small amount of force may have a greater impact on the spacecraft.

"The first cabin penetration experiment begins!"

Following an order from the ground command center, Fei Junlong slowly stroked the bulkhead of the spacecraft and controlled his body to float forward slowly.

For mobile training in space, although it has also been carried out many times on the ground.

But after all, there are many differences from space.

Fei Junlong didn't dare to be careless.

But fortunately, the spacecraft's adaptive attitude balance system is still very powerful, and there were no problems in the process.

Fei Junlong successfully passed the junction between the two cabins and entered the orbital cabin.

Next, he will conduct many scientific experiments in the orbital module.

Among them, there is the space vegetable cultivation project.

This in itself is also an attempt at space ecological recycling.

Vegetable varieties with a relatively short growth cycle are used, including edible green vegetables that can grow within seven days of planting.

This time, they will live in space for about eight days.

Not surprisingly, these vegetables were already edible when they returned to Earth.

Of course, because they didn't bring any kitchen utensils this time, they actually couldn't eat in space.

In addition, there are many space experiments.

Including the breeding of biological strains, the cultivation of metal crystal growth, etc.

Nie Haisheng also has many tasks, including launching a companion satellite.

On the side of the spacecraft, a small satellite was released.

Such a small satellite integrates high-resolution cameras and communication equipment.

Can assist in completing some observation work about the exterior of the spacecraft.

Due to the special nature of the manned spacecraft's work, the two astronauts cannot rest at the same time.

There is always an astronaut on duty.

To prevent some emergencies from occurring.

On the second day after the manned spacecraft entered space, the two of them worked together.

Another dangerous experiment begins.

It can even be said that this is the most dangerous task in this mission.

That’s a spacewalk!

There are many technical problems that need to be overcome during space walks.

The first is the problem of opening and closing the cabin door, and the problem of entering and exiting the cabin.

The second is the astronaut's extravehicular walking suit.

Finally, there is the possible connection problem between the astronauts and the spacecraft.

It can be said that there are many problems and the dangers are very high!

After completing the oxygen intake and nitrogen removal work.

With Fei Junlong's help, Nie Haisheng put on a full set of extravehicular walking clothes.

This extravehicular walking suit is a product independently developed in China.

In fact, the spacecraft also carries a set of "Sea Eagle" extravehicular walking suit produced by Damao.

If any problem arises, Fei Junlong will put on the extravehicular walking suit to assist.

Fei Junlong gave Nie Haisheng a "everything is intact" gesture.

Then the airlock cabin was pushed out and the door on one side was closed.

In the airlock cabin, the pressure began to slowly release.

When the pressure in the airlock reaches a level close to the perfect level, it's time for Nie Haisheng to leave.

Nie Haisheng cautiously approached the exit hatch with excitement.

Use the tool to slowly open the exit hatch.

Then the darkness and starlight in the sky came through the small hatch.

The special optical glass design allows him to resist those ubiquitous cosmic rays and see his situation clearly.

This time out of the cabin is not just an experiment.

Nie Haisheng still needs to complete a task, which is to complete the lifting work of a camera's nail arm.

His thick hands tightly grasped the airlock door,

It was as if once he let go, he would drift into the helpless dark space.

After carefully walking out of the hatch, Nie Haisheng raised a small national flag in his right hand and waved it several times at the live camera.

Above the ground, there is now a sea of ​​enthusiasm.

Everyone has seen that their astronauts completed their first space flight.

After stepping out of the space capsule, Nie Haisheng relaxed a lot.

After briefly greeting everyone on the live broadcast, I started to complete my work.

Using the tools I brought with me, I adjusted the position of the camera a few times.

The work is not difficult, it can even be said to be simple.

But since he was in space, the difficulty was so high that it was unbelievable on the ground.

Nie Haisheng spent a few minutes and followed his path back to the airlock.

After closing the hatch tightly, the air pressure inside the airlock began to slowly rise.

This space walk can be said to have been completed beautifully! (End of chapter)
