On the outer space shuttle more than 400 kilometers away, Xu Chuan was not very worried about the impact of the unexpectedly observed super typhoon.
For China, there are complete means and related measures for the formation and monitoring of typhoons.
As long as you prepare in advance, it won't be a big problem.
After staying in low-Earth orbit for several hours, after completing the docking with the Tiangong Space Station and replenishing a batch of supplies for the space station, the Xinghai also started its return journey.
As planned, under the instructions of the ground command, the aerospace engine restarted. The main engine swaying at the tail of the space shuttle and the auxiliary engines on the flanks emitted a blue-white light, pushing the huge fuselage to complete the orbit change.
Heading towards the ground.
After completing the internal inspection of the space shuttle, Zhai Zhigang quickly came to the crew cabin and reminded Xu Chuan and the other two 'tourists'.
"Academician Xu, Prince Faisal, Mr. Abdulrahman. The Xinghai is about to return. Please put on your spacesuits and be prepared."
Xu Chuan smiled, and while struggling to put on the spacesuit in the cabin, he replied: "I'm already wearing it."
On the side, the bearded Prince Faisal half-entered the space suit and complained: "You have to put this thing on very slowly, it's really troublesome!"
Zhai Zhigang glanced at him expressionlessly and said, "For your safety, Prince, it's best to put on a space suit just to be on the safe side."
To be honest, from the bottom of his heart, he didn't have much favorable impressions of the Middle Eastern prince in front of him.
Although as a soldier himself, he should not have such a position and act according to orders.
But this time Academician Xu Chuanxu did not say that he was deceived by this guy, but it also had something to do with him.
If something goes wrong during this space trip, he will be the sinner of China and even the entire human civilization.
Prince Faisal shrugged his shoulders, perhaps sensing something, and said no more, struggling to put on the spacesuit in the cabin.
Compared with the gravity environment on the earth, wearing this thing in the gravityless space is more troublesome than imagined. It took the group more than half an hour to put it on completely.
At the same time, in the cockpit, Zhai Zhigang, who was well prepared, contacted the ground command center. Under the ground's dispatch, he reached out and pressed a few buttons on the control panel in front of him.
"The aerospace engine is warmed up, the Xinghai reactor is ready, and the navigation route has been determined..."
Accompanied by cold mechanical sounds, hundreds of kilometers above the low-Earth orbit, a silver-white space shuttle drew a perfect curve with a light blue-white tail flame, heading towards the blue star.
The planet flies away.
.......
For a spacecraft, if we want to talk about the most difficult parts of the entire voyage, there are two.
The first is to escape from the gravity well and enter low-Earth orbit, commonly known as 'orbit entry', and the second is to return and enter the atmosphere from low-Earth orbit.
Strictly speaking, with current aerospace technology, returning to orbit is more difficult than entering orbit.
Generally speaking, when a spacecraft returns to the ground, it generally goes through four stages, namely deorbiting, transition, re-entry and landing.
Since the spacecraft flies too fast, it must solve two major problems during its return: first, reduce air friction and prevent it from burning due to high temperatures;
The second is to use a soft landing method to avoid damaging the spacecraft.
Each of these four points can be described as a life and death difficulty for a traditional space shuttle or spacecraft.
However, for Xinghai, which adopts more advanced propulsion technology, the difficulty of these three steps of deorbiting, transition and landing has been reduced countless times.
The only danger is the step of re-entering the atmosphere.
It is not just because the spacecraft must be controlled to enter the atmosphere at a predetermined position and attitude, so that the reentry angle cannot be too large, otherwise it will burn out; and it must not be too small, or it may not fall down.
In addition, the space shuttle enters orbit extremely quickly. Even if it decelerates in low-Earth orbit in advance, the friction between its fuselage and the atmosphere will still generate extremely high temperatures.
Multiple difficulties are a considerable test for the performance of the spacecraft itself and the skills of the pilot.
Therefore, whether it is a traditional spacecraft, a space shuttle, or any other manned spacecraft, returning from low-Earth orbit is always a technical job.
In the cockpit, Zhai Zhigang and Chen Dong were very alert and focused on controlling the Xinghai to cut into the transition route.
The landing did not take long. When it dropped from the 'off-orbit section' at an altitude of 160 kilometers to the upper atmosphere at an altitude of 50 kilometers, the speed of Xinghai also began to gradually decrease.
Soon, sufficient air in the atmosphere replaced the xenon in the wing refrigerant tank, and the red-purple tail flame ignited again at the tail of the space shuttle.
Dragging a long and narrow flame, the Xinghai entered the atmosphere from the northwest of China and flew towards the east.
The landing address for this voyage is not at the Xiashu Space Center in Jinling, but at a military airport in the capital.
The red-purple tail flame swayed in the air, looking particularly eye-catching in the blue sky and white clouds.
In the airport on the ground, Wu Yuankang of the Space Administration stood in the sub-control room of the airport, carefully accompanying an old man and waiting quietly.
"Let's go, our 'hero' has returned successfully, let's go take a look."
Looking at the picture from the monitoring screen in the sub-control room, the old man said with a smile, but the pronunciation of the word "hero" was a bit strong.
Wu Yuankang nodded and walked out together. Behind him, two medical staff followed him with a portable medical kit on their shoulders, ready for examination.
It was not his idea to ask the Xinghai to land in the capital, but the request of the man in front.
Maybe he wanted to 'criticize' that person's adventurous spirit.
Although it is difficult for the senior management to change his mind about that person, and most of the time he is still half-coaxed, but no matter how much he talks about this kind of space travel adventure, he is afraid that he will land on the moon next time.
.
This chapter is not over yet, please click on the next page to continue reading! Manned spaceflight in low-Earth orbit is relatively safe. Even if something unexpected happens to the Xinghai, they still have other spacecraft and launch vehicles in reserve.
Bring people back.
But the moon landing is different. Currently, the only one in China that has the ability to complete a manned moon landing is the Xinghai space shuttle.
If someone thinks that space travel is just that dangerous and follows the space shuttle to the moon next time, it will be a big mistake.
Of course, another aspect of allowing the Xinghai to land in the capital is to have the medical staff here carefully check on the body.
Although it is a short-distance low-Earth orbit voyage, Xinghai also has complete anti-radiation means, but space travel does have some risks after all.
Compared with Jinling, the medical resources here in Beijing are much better.
...
The red-purple tail flame is like a brilliant sunset on the horizon, and the silver-white Xinghai emerges from the blue sky amid white clouds.
The short time passed by like a shuttle, and on the spacious runway, the swaying red-purple tail flame gradually disappeared.
The engine was shut down, the drag chute was sprayed backwards, and the speeding space shuttle gradually came to a stop.
In the cockpit, Zhai Zhigang's hand that was tightly holding the control rod slowly loosened his grip, and he sat down on the chair as if he was exhausted, and took a long breath to relieve the turbid air in his chest.
Although the mission of this flight was ordinary, it was the most frightening of all the flights in his life.
Fortunately, everything went well.
In the crew cabin, when the space shuttle entered the atmosphere and returned to the embrace of Mother Earth, Xu Chuan had already taken off his spacesuit.
When the plane landed smoothly, he stood up from the space chair and walked toward the door that was about to open.
Looking at the blue sky, Xu Chuan felt a sense of satisfaction and wonder in his heart.
Space travel was something he had never done in his previous life. Less than ten years after his rebirth, he stood hundreds of kilometers in the air overlooking this red land.
...
After walking down the ramp from the space shuttle, there was no one on the open runway of the airport to greet them, but it could be seen with the naked eye that there were many soldiers with guns and live ammunition standing guard at the posts in the distance.
At this moment, a familiar old man walked over from the exit.
Seeing this person, Xu Chuan quickly walked over and said hello: "**, why are you here?"
The old man looked him up and down, and then smiled and said, "Is it fun up there?"
He is probably the first person in the history of spaceflight who dares to take a space shuttle designed and manufactured by himself.
After all, manned spaceflight has extremely high physical requirements for astronauts. Traditional chemical fuel rockets can accelerate up to 6 or 7 G during launch and return.
Most ordinary people without training cannot withstand this kind of super acceleration.
"Forehead....."
Hearing these words that sounded like criticism and questioning, Xu Chuan was dumbfounded and thought for a long time before replying: "It's okay..."
The old man shook his head and sighed: "You are so courageous. If something unexpected happens, how do you want me to explain it to your parents?"
"It's not that I won't let you go up. At least in this situation where our aerospace technology has only just started, we can wait a little longer."
"You are still young, even if you have a dream, so what if you wait two years..."
Looking at Xu Chuan, the man was shaking his head and nagging like a parent or elder.
Standing aside, Xu Chuan had an embarrassment on his face. He didn't want to listen, and he didn't want to listen. He wanted to leave but couldn't. His whole body was numb.
This was probably the first time someone other than his parents had nagged him like this, and it was someone he could only stand there and listen to.
Fortunately, it didn't take long before Prince Faisal and Abdul Rahman from the United Arab Emirates came down from the space shuttle to help him out.
After all, he is the prince from the Middle East. Since he has arrived, the old man still has to say hello in a friendly way.
"Huh~"
He breathed a long sigh of relief. Xu Chuan, who had escaped disaster while the two sides were communicating, was just about to sneak away quietly when he was pulled back by Director Wu Yuankang of the space agency.
After coming down from outer space hundreds of kilometers high, you need to undergo a comprehensive physical examination no matter what.
Although he felt that his physical condition was fine, he could not bear the demands of his superiors. Xu Chuan, Prince Faisal and others who went to heaven together this time were taken to the 301 People's Liberation Army General Hospital and admitted to the hospital.
Various instruments and equipment were used on the body, but acupuncture was missing.
Although he was not interested in these things, Xu Chuan also knew that this was for his own good. After all, he was going to outer space, and no one would be at ease unless he checked thoroughly.
Fortunately, although he lives in the hospital, his daily activities are not restricted.
Of course, this unrestricted means that there are no restrictions on activities in the hospital. As for discharge, according to the words of the old experts in the hospital, it still needs to be observed for a period of time.
As for how long the observation will take, it’s hard to say. It could take as little as a week and a half, or as long as several months.
Hearing these words, Xu Chuan's face turned pale.
If he really needs to stay in the hospital for several months and half a year, wouldn't that be a lie?
After all, there are so many things outside waiting for him to deal with, so how can he spend so much time here.
However, those veteran experts wanted to observe one by one, and even took the example of astronauts also needing to be hospitalized for recovery for the first time to go to space. Xu Chuan had no choice but to take one step at a time.
In the ward, Xu Chuan took out his mobile phone from his pocket in boredom and scrolled through the news.
A report from NASA caught his eye.
This is news related to manned spaceflight, or space travel.
After experiencing the failure of the Artemis lunar module, the United States and NASA launched the first commercial spacecraft launch plan with an all-civilian crew through SpaceX in order to make a comeback in the aerospace field.
According to news reports, the commercial spacecraft named "SpaceX Crew Dragon" will be launched a week later, on September 15.
After reaching orbit, the spacecraft will dock with the International Space Station and stay in a low-Earth orbit of 400 kilometers for 24 hours.
In addition to NASA's "former astronaut" Michael Lopez-Alegría, there are three tourists involved in this "space travel" plan.
They are Larry Connor from the United States, Mark Passi from the Maple Leaf Country of North America, and Iltan Stibbe from Israel.
Each of the three passengers had to pay 65 million yuan for this space trip.
After reading the news, Xu Chuan had nothing else in his mind, only a number.
Sixty-five million meters of gold!
Still alone!
"Oh my god, are these people so rich?"
Seeing the news reported by NASA, Xu Chuan couldn't help but swallow his saliva.
Sixty-five million yuan. According to the current exchange rate, one person is worth 290 million yuan, and three people are almost 1 billion yuan.
Good guy, you're not that quick to rob a bank, are you?
Taking a deep breath, Xu Chuan suddenly remembered something. He quickly opened the photo album on his phone and found the photos he took on the Xinghai.
It would be outrageous for him not to spend this money properly!
