After 50 years, with the efforts of generations of aerospace workers, the greatest moment in the history of China Aerospace has finally arrived.
"Chang'e 11, are the preparations completed?"
"Finish!"
"Chang'e 11, are you ready?"
"Report to the control center, ready!"
"Listen to my command and reverse engine ignition!"
"Reverse engine, ignition successful!"
As the reverse engine started, Chang'e 11 circled for more than half a circle in the elliptical orbit before decelerating again and continuing to decelerate.
As we all know, when recovering satellites and changing orbits of high-orbit satellites to low orbits, they are all accomplished by decelerating.
Because the speed slows down, the gravitational force exerted by the earth on the satellite is greater than the centripetal force required for the satellite to make a circular motion around the earth, and the satellite will be pulled towards the earth by the gravitational force.
In the same way, the launch of high-orbit satellites is achieved through acceleration. The satellite is first launched into a low orbit, and then the satellite is accelerated to fly toward the high orbit.
To put it simply, the principle is the battle between centripetal motion and centrifugal motion, gravity and centripetal force!
At this moment, if Chang'e 11 wants to land on the moon, it must jump from a high orbit to a low orbit and perform centripetal motion.
Therefore, let it slow down, slow down as much as possible, and then be pulled toward the moon by the moon's gravity!
From high orbit, all the way to low orbit.
"Chang'e 11 continues to slow down, the reverse engine is running normally, and the altitude from the moon continues to decrease!"
At this moment, Ying Yue and others were tightly tied to their safety belts. As the spacecraft bumped all the way, when they descended to a certain height, they could see the moon's surface through the glass windows.
“As expected, it’s full of craters and craters!”
Ying Yue sighed.
The Eagle-Headed God also nodded repeatedly. He was much more excited than Ying Yue. His whole body was no longer as calm and calm as on earth, and he became extremely excited.
He was breathing rapidly, his chest was rising and falling violently, and his face was flushed.
As you can imagine, he waited for a day, which was too long!
As it continued to descend, the reverse engine suddenly stopped operating, and then the landing engine at the bottom of the spacecraft ignited successfully.
This also means that the spacecraft began to fall towards the moon surface under the influence of the moon's gravity, which means that the moon landing operation has entered the final stage.
"The landing engine ignited successfully!"
"Chang'e 11 keeps descending!"
"Chang'e 11 begins to slow down!"
"decline!"
"slow down!"
Chang'e 11 fell to a certain level and began to descend at a constant speed.
"Final landing time!"
"Chang'e 11, perform manual control to find a suitable landing site!"
"receive!"
Through the glass window, you can see the messy pebbles and uneven ground below. This is not an ideal landing spot.
Chang'e 11 can only continue flying and look for flat land.
Finally, after flying forward for a certain distance, it found a flat corner, and then landed smoothly under the manual control of the astronauts.
"boom--"
Finally, there was a slight touch of the ground below, and Chang'e 11 stopped falling directly and successfully landed on the lunar surface.
"Click——"
The picture is frozen at this moment!
The entire ground control center was completely silent. Everyone was staring blankly at the big screen, completely forgetting to react.
The air is frozen!
Time is frozen!
The whole world is also locked down!
However, the next moment——
"Success!"
"Chang'e 11 successfully landed on the moon!"
"see it?"
"Did you see it?"
"They succeeded!"
"They succeeded!"
The entire control center suddenly erupted into an unprecedented burst of cheers.
Everyone jumped up high, danced, roared with excitement, and let out overwhelming cheers like a tsunami, which almost broke the ceiling.
With tears in their eyes, people hugged each other, slapped each other on the shoulders, roared and whispered to each other, venting their excitement and happiness.
Dean Wang tightly hugged an old expert with white hair next to him, patting his back constantly, crying and laughing: "Old Zhu, it's successful, we're successful, Chang'e 11 is successful, you
see it?"
"I saw it! I saw it! Wuwuwu..."
Countless experts held their heads and cried, countless aerospace workers shed tears, and countless people were so excited that they couldn't contain themselves.
I have been waiting for this day for too long!
Fortunately, the wait is finally here!
This scene lasted for nearly ten minutes before gradually calming down. People wiped their eyes and turned to look at the big screen again, looking at the spacecraft sitting quietly on the surface of the moon.
"Call the control center, this is Chang'e 11!"
"Call the control center, this is Chang'e 11!"
At this moment, the astronaut's voice sounded from the speaker on the side of the big screen, with a trace of noise. It was not very clear, but it spread clearly throughout the entire hall.
"The voice is Xiao Huang's voice!"
The commander-in-chief of the lunar landing, the white-haired old man whom Dean Wang called Lao Zhu, grabbed the microphone and responded with a trembling voice: "Roger, this is the ground control center!"
As if he was afraid that Chang'e 11 would not be able to receive it, Lao Zhu said again: "Got it! This is the ground control center!"
"Report to the control center that we have successfully landed. Now I can't wait to go out and take a look at this mysterious land. Is it okay?" Xiao Huang said excitedly.
"Control center received it!"
Lao Zhu took a deep breath, suppressed the excitement in his heart, and said: "Chang'e 11, I now order you to stay in the cabin, have a good sleep, and then have a good meal!
Finally, check the instruments, fuel devices, and oxygen supply on the ship, and then try to land on the moon after everything has been checked accurately!"
"Chang'e received it on the 11th!"
Although the three astronauts could not wait for the orders from the control center, they still faithfully carried out the orders from the control center.
At this time, the ground control center is always the wisest!
"call……"
The commander-in-chief of the lunar landing, Lao Zhu, put down the microphone, wiped the cold sweat from his forehead, and let out a long breath. He had directed countless satellite launches at the Jiuquan Satellite Launch Center for so many years, but he had never felt so nervous as this time.
At this moment, Thunder God, Wolf God and others came over and said with a smile: "Lao Zhu, it's time to let our people out!"
Lao Zhu was stunned: "Don't they need to rest?"
"no need!"
Thor shook his head: "The spaceship of the Pantheon landed 20 minutes ago. Although it is farther from Galileo Crater than Chang'e 11, we can't rest!"
"We must get ahead of them and reach Galileo Crater!"
The Wolf God also said seriously.
"Oh well!"
Lao Zhu nodded slightly. This operation was divided into two aspects. Their satellite launch center was only responsible for sending people to the moon. As for the rest, they couldn't control it.
Because this is an order from above!
"Call Chang'e No. 11, please answer when you receive it!"
"Call Chang'e No. 11, please answer when you receive it!"
"Chang'e received it on the 11th!"
Lao Zhu said: "Listen to my order and ask the two comrades from the special department to prepare for the moon landing!"
"ah……"
PS: I originally wanted to publish this chapter later, but I thought I might as well publish it together. I would like to ask everyone for support, recommendation tickets, monthly passes, subscriptions, etc. to give it a go!
