Peng Guochen pointed to the ceiling with his finger and said, "They should be on...the top now!"

"above?"

Soon, everyone including the Great Elder reacted. "

The Great Elder frowned and said, "You mean, both Qiao Ting and Chen Xin are on that space plane?"

Peng Guochen said: "It should be. The original text of this message is that we are on our way home, at an altitude of [-] kilometers, using the special encryption method of the Second Ministry, and the secret note of Lieutenant Colonel Qiao Ting. It should not be wrong. gone."

At this moment, the staff responsible for monitoring in the front hall began to boil: "It moved, it is lowering its orbit, the speed is 6000 meters per second, and it starts to accelerate, 7000 meters, 8000 meters, ten kilometers... ten 6000 rice!"

"Oh my god, are they crazy? How to slow down when this speed falls, it will burn directly in the atmosphere."

The atmosphere in the hall suddenly became tense, and even the Great Elder and the others began to pay close attention to this situation.

"what happened?"

The Great Elder consulted one of the aerospace experts.

The aerospace expert said: "Chief, I think you also know that the technical difficulty of returning a manned spacecraft is complicated, and accurate operation is very important. The aerospace plane in space now is different from our spacecraft. We can use the It is compared with the space shuttle of the United States. Before landing, the general space shuttle must hover in the air for an hour, and then ignite the engine to slow down and lower the orbit. This process will last for 25 minutes, and the space shuttle will rush into the outer layer of the atmosphere. , the altitude drops to 129 kilometers (80 miles). When the space shuttle enters the atmosphere at a speed of 9 kilometers per minute. It is like an unpowered glider. And the belly of the space shuttle will continue to slow down towards the surface of the earth, both The angle between them must be kept at about 40 degrees. This angle is crucial when entering the dense atmosphere. If the angle is too small, the space shuttle will bounce back into space. If the angle is too large, the distance between the space shuttle and the space The friction is overheated, and the supersonic air friction makes the temperature of the ceramic heat shield outside it reach 1650 degrees Celsius (3002 degrees Fahrenheit). The Columbia space shuttle in the United States crashed because of the insulation ceramic tiles falling off, so the spacecraft was in the You have to be very careful when returning to the voyage. Any mistake can be fatal."

The Great Elder frowned all of a sudden.If it was true that if something happened to the aerospace plane as these scientists said, the situation would be delicate. He didn't know how much the war bureau spent to build this aerospace plane, but it must be worth a lot.Only with its existence can the balance of the situation be maintained.Without it...the situation would become complicated again.

And this plane also involved the lives of Qiao Ting and Chen Xin.Chen Xin was fine, he was a member of the War Bureau, but Qiao Ting's grandfather, Qiao Lao, had a wide range of influence in the military and scientific circles.In case something happens, it's hard to explain to Mr. Qiao.

The staff in the lobby of the flight control center are still busy.

"Attention Yuanwang-5, please pay attention to Yuanwang-[-]! The target will enter your measurement and control range in [-] minutes, please pay attention to tracking, please pay attention to tracking!"

"Yuanwang No. [-] understands!"

"Please pay attention to Dar es Salaam Station, please pay attention to Dar es Salaam Station, pay attention to observe its orbit data, and handover with Yuanwang-3 in [-] minutes."

"Dar es Salaam understands!"

……

The Great Elder asked the aerospace expert: "Old Nie, do you think there is still hope for this plane to slow down later?"

Qiao Lao shook his head and said, "I'm not sure. After all, the opponent's technology is far superior to ours. Maybe this is the best return plan for them."

Having said that, Qiao Lao still frowned, obviously not very optimistic about the return method of the Dream.

In fact, at this time, Qiao Ting and Chen Xin were also arguing inside the Dream.

"Chen Xin, you are crazy, you are really crazy!"

The three of them sat in the front row of the cockpit, Qiao Ting and Ling Wei had already put on their space suits.

After completing the test of the laser weapon, Chen Xin proposed to return to the voyage. Of course Qiao Ting and Ling Wei didn't care about it, and then Chen Xin asked Gang Bian to send a telegram to the Second Department of the General Staff in Qiao Ting's tone, although Qiao Ting had been waiting. It is by Chen Xin's side, but every communication between her and the country is within the control of Gang Bian, so it naturally looks good when it imitates.Of course, this text message is not just a reminder, there is also a very important hidden meaning in it - because the destination of Chen Xin's return flight this time is not Mogadishu, but China.

After deciding to return, Dream's engines were turned on again, pushing Dream out of geosynchronous orbit.

Of course, at this time, Qiao Ting didn't notice anything unusual.

Because there is no reference point for flying in space, especially the sky above the geosynchronous orbit is pitch black, so Qiao Ting didn't realize how fast it was.

It wasn't until Chen Xin asked the Dream to point the nose at the earth that Qiao Ting felt something was wrong, because the earth was rapidly growing in size in her field of vision.

"Chen Xin, what is our current speed?"

Chen Xin smiled slightly and said, "About 6000 meters per second!"

Qiao Ting's face turned pale all of a sudden, and she yelled, "Chen Xin, turn around and slow down quickly, you are crazy, you will be burnt to pieces when you return to the atmosphere at this speed!"

Chen Xin laughed and said, "Let's smash the body to pieces, so it's worth the flight today anyway!"

Qiao Ting was speechless immediately, and said, "Chen Xin, you bastard, even if you don't think about yourself, you should think about Weiwei! Don't you think it's hopeless to fight against NATO, so you commit suicide in this way?"

Chen Xin curled his lips, turned his head and asked Ling Wei, "Wei Wei, I'll take you home, okay?"

Ling Wei smiled and nodded, "Okay!"

Chen Xin then turned to Qiao Ting and said, "Look, how much Weiwei trusts me!"

Qiao Ting was taken aback for a moment, and asked doubtfully, "Are you sure you can return safely at this speed?"

What is the concept of 6000 meters per second, its speed has exceeded the third cosmic speed, which is enough to allow Dream to escape from the sun's gravity and carry out interstellar flight.

Chen Xindao: "Do you think I'm going to make fun of my own life? When did you lose confidence in Zhan Huju in your eyes!"

Qiao Ting opened her mouth, but she didn't speak in the end. She knew that she had fallen into a thinking barrier. This speed really challenged her common sense.

Qiao Ting herself is an expert in materials science, and has a deep knowledge of aerospace materials.

If the Dreamer can successfully return at this speed, it means that the structural strength and heat insulation system of the Dreamer have far exceeded the existing material technology of human beings.

How many things did the Bureau of War and Disregarding not come up with?

At this moment, Qiao Ting suddenly felt a chill in her heart.

In just less than half an hour, the Dream was inconceivably lowered from a height of more than 3 kilometers to an orbital height of [-] kilometers.

At this time, both Qiao Ting and Ling Wei could feel the suffocation brought by this extreme speed.

Chen Xin remained calm, he said: "Dream is ready to enter the deceleration program!"

Dream's AI said: "Dream understands that after five seconds, it will enter the deceleration procedure at an acceleration of 1.5g per second. All passengers, please get ready."

Chen Xin reached out and grabbed Ling Wei's hand, looked at her slightly pale face and said, "Weiwei, don't be afraid, I have everything!"

"Ok!"

Ling Wei nodded and gave Chen Xin a warm smile.

Qiao Ting turned her head away, pretending she didn't see anything!

"Five, four, three, two, one... turn around!"

The fuselage posture of the Dream was reversed in an instant, from the original nose pointing at the earth to the outer space in an instant, and the tail pointing at the direction of the earth!

"Engine fire!"

In an instant, the three of them were pressed tightly on the seat by inertia. Compared with the acceleration of 1g per second during take-off, this time 1.5g made both Ling Wei and Qiao Ting a little bit strenuous.

Chen Xin shouted to the dark space outside the porthole: "Let's go home!"

Of course, Chen Xin had his own intentions in returning to Earth in this way.

……

At this time, whether it is NASA, the European Aeronautics and Space Agency, or the aerospace departments of China and Russia, they are all paying attention to the return of this aerospace plane.

Previously, the dream crashed into the earth at such a high speed that they almost thought that the other party had launched a suicide operation. Who would have thought that when the height of 1000 meters was still [-] meters above the ground, the other party would suddenly start decelerating. Guoguo's show off.

Due to the high cost of rockets in modern aerospace, the weight of each launch is calculated in kilograms.

Therefore, no matter whether it is a space shuttle or a spacecraft, the fuel carried in outer space is only enough for maneuvering orbit change. Once the fuel is exhausted, the mission of the spacecraft has been completed. The next one returns by itself like a shooting star.

But this aerospace plane is different. It dared to start the engine to brake at such a high altitude, which means that the fuel on it is still more than enough after the previous launch and maneuvering orbit change.

This is too speechless, do they use nuclear power?

Otherwise, judging from the energy contained in chemical fuels, human beings do not have any kind of fuel that can reach their level.

From this point of view, the combat capability of this aerospace plane will undoubtedly be improved to a higher level, because it can continuously maneuver and change orbits, capture or destroy enemy satellites, even communication satellites in geosynchronous orbit and polar regions. Navigation satellites in orbit cannot escape its pursuit.

This is a big killer that is far more terrifying than the space shuttle.

My God, where did these guys come from? How come there are so many incredible weapons.

The more people who know more about aerospace, the more they can feel the horror behind it. (To be continued..)
