NASA engineers guessed accurately.

Compared to other reentry spacecraft, the Xiangrui does have a lot of fuel at its disposal when it returns to home.

With 21% of the working fluid remaining, it may not be enough to fly from the surface to low-Earth orbit, but it is not a problem to accelerate the spacecraft to the second cosmic acceleration away from the Earth-Moon system and heading straight for Mars.

After moving from the 100-kilometer "re-entry section" to the 20-kilometer "landing section", the speed of the Xiangrui has been reduced to Mach 7 due to the combination of air resistance and engines. And the location at this moment is already the airspace of the Western Regions of China.

At this speed, there is basically no suspense about a successful landing.

Russian Space Agency.

Looking at the high-speed moving green dot on the radar screen, a hint of disappointment flashed across the face of the man in a black suit with a dignified face.

If the Xiangrui fell in Russia or the Pacific Ocean, of course he would not mind "helping" the Chinese. It's just a pity that God doesn't seem to give him the opportunity to reach out to his "old friends".

There's nothing left to see.

At this height and speed, even he was confident that he could drive this thing back.

"Let the Pacific Fleet be put on standby."

Dressed in a Russian military uniform, the man standing next to him stood up and gave a military salute.

"Yes."

……

The faint blue arc light emerged from the clouds, as if driving the colorful auspicious clouds, and the silver auspicious number appeared in people's field of vision.

At this moment, there was already cheers in the Jinling Space Launch Center and the ground command center.

As the sound of "the launch mission was a complete success" sounded, seeing the chief engineer Hou Guang standing in front of the console take off the headset on his head, the staff in the command headquarters suddenly burst into cheers as if they had been holding their breath for a long time.

In the past 24 hours, they have almost stuck to their posts in shifts, many of them have not even slept for less than two hours, and some have not slept from the beginning.

After all, this is where the auspicious is located. Women's Airlines.

For them, this aerospace aircraft, which embodies the world's most advanced fusion technology and electric propulsion technology, is like their children.

Not to mention, Professor Lu is still on it.

Quite a few had even thrown their headsets on the table and ran from the command room to the launch site outside to greet their heroes.

Chen Yushan, who has been standing here since she came here last night, is already in tears at this moment.

I was worried that I hadn't slept all night, but I finally came back safely.

Yan Yan, who was standing next to the door of the command room and carrying a portable medical kit on her shoulder, glanced at the woman, and then at Wang Peng, who was also standing by the door, and couldn't help but tease.

"That guy, you're in a lot of trouble this time, aren't you?"

"It's okay," Wang Peng sighed, reached out to touch the cigarette in his pocket, but suddenly thought of the ban on smoking here, so he silently took his hand back, "I also know that this guy's matter is not easy to deal with, so I didn't bother me too much." ”

At most, he just reprimanded him on the phone.

Yan Yan glanced at him in disbelief.

"That's it? No punishment? I don't believe it. ”

"It's really no ......" Wang Peng hesitated, and then made a helpless expression, "Okay, probably the year-end bonus is gone again...... To be honest, after all this time around him, I didn't expect this thing. ”

Yan Yan shook her head with a smile and looked at the woman named Chen Yushan, her eyes drifting to the door with her footsteps.

"Let's go, let's go too...... Hopefully he didn't make himself half-paralyzed this time. ”

Yang Guangbiao, who had been standing next to him and had not spoken, coughed and said.

"Count me on, don't crow's mouth."

What happened at the site of the last controlled fusion project is still fresh in his memory today.

……

The engine shuts down.

The landing gear was lowered and hit the ground heavily, carrying the landing shuttle and taxiing along the runway.

Immediately after that, two pairs of deceleration parachutes erupted backwards in unison, and the string in Nie Yun's heart, which was tense to the limit, finally slowly relaxed.

With his hands off the grips, he leaned back on the seat as if he had lost his strength, only then did he feel that his back was completely soaked. Only he knows what kind of responsibility he has taken on and what kind of pressure he has borne in these 24+2 hours.

But all this finally ushered in the final victory.

Suddenly, he saw the people rushing towards the plane.

There are ground crews from the launch center, engineers from the command, and journalists from CTV......

A smile finally appeared on his tired face, and he suddenly remembered the day the J-20 made its first test flight.

"It's like a dream......"

Unlike Nie Yun, Lu Zhou didn't spend his time on sentimentality.

Having left the passenger seat, he was already standing in front of the porthole, staring at the wings outside the window with a thoughtful expression.

Noticing the expression on his face, Nie Yun asked casually.

"Any questions?"

"It's not a big problem," Lu Zhou continued, after thinking for a moment, "but it seems that the design of the wings and engines still needs to be readjusted. ”

“…… I think it's pretty good. ”

"But we can do better," Lu Zhou smiled and said with a smile retracting his gaze from the window, "Sure enough, I still have to fly along to find out." ”

Nie Yun: "......"

Nie Han: "......"

Hearing his words, the two of them always had a sense of foreboding......

……

The three of them helped each other take off their spacesuits in the cabin.

The moment they stepped out of the hatch, the three heroes were immediately surrounded by an excited crowd.

Dumping the interview with Nie Yun and Nie Han, Lu Zhou left the side of the Xiangrui. Just as he was about to go to the ground command headquarters to find Hou Guang to tell him his opinion on the improvement of the design of the Xiangrui, he saw a man with deep bags under his eyes and a haggard face walking up to him.

Lu Zhou stared at him for a long time before he said in an uncertain tone.

“…… Director Lee? ”

"It's me!"

Lu Zhou: "...... Uh, why are you emaciated like this? ”

Could it be that he flew a few laps in the sky, and how many years have passed on the earth?

It's not scientific......

The wrinkles were huddled together, and Director Li sighed with a sad face.

"It's not that you're worried yet!"

Just as he was about to say something, another old man walked by.

As soon as he saw this face, Lu Zhou suddenly shook the grass in his heart.

Yuan Huanmin?

Hold the grass!

Why is this guy here?

Just when Lu Zhou was having a headache about whether to pretend not to see it and leave, he saw the old man walking towards him, grabbed his hand, and had tears on his face.

"I misunderstood you...... Allow me to apologize to you! ”

Lu Zhou: "......??? ”

What misunderstanding?!

What the hell is going on???

However, before Lu Zhou could recover from his confusion, a beautiful figure suddenly rushed out of the crowd and hugged him.

"Great...... You're okay! ”

Seeing this scene from afar, Yan Yan, who was walking from the control tower, suddenly stopped.

Although she was relieved to see that the object of protection was safe and sound.

But for some reason, she suddenly felt a little pain in her stomach......
