Chapter 1,184 The person responsible for making fun
Capital Aerospace Measurement and Control Center.
When Qin Tao and Max arrived as quickly as possible, the orbital module had already gone through a series of orbit changes and entered the lunar orbit. At this time, the Aerospace Measurement and Control Center was conducting final measurement and control, preparing for the next step of orbit changes.
docking.
"Because the fuel of the lunar module is limited, we try our best to use the fuel of the orbital module to change orbit." Jiang Weixing, the person in charge of the measurement and control center, told the two people. This was also the original plan discussed, mainly to introduce it to Qin Tao.
"The two parts of fuel should be about the same, right?" Qin Tao was a little curious.
"Of course it's different. The lunar module should have more fuel. After all, the lunar module has to take off from the moon's surface and get rid of the moon's gravity." Max explained simply.
This is just like launching from the surface of the earth. A rocket of several thousand tons can only launch a few tens of tons of payload. Most of the launch energy is wasted on getting rid of the earth's gravity. However, it is easier to continue flying to space from the earth's orbit.
too much.
Fortunately, the moon's gravity is only one-sixth that of the earth. Otherwise, with the current capabilities of chemical rockets, it would not be easy to land on the moon's surface and then lift off.
This is also the reason why you must use a liquid oxygen methane engine to go to Mars. If you fly there, it will be good if you can land. The fuel will definitely be completely consumed. Only by using local materials to make fuel can you come back. Otherwise, detection will not be possible at all.
Mars target.
Only a layman like Qin Tao doesn't understand this simple truth.
"Measurement and control has been completed, and the optimal docking orbit is being calculated..." The measurement and control center was very busy, reporting voices sounded from time to time, and at the same time, the computer was also calculating rapidly, three seconds later.
"The optimal docking orbit has been calculated! It will be sent to the orbital module and lunar module, and the orbit change operation will be carried out when the orbital module reaches its third lap!"
"So fast?" Qin Tao was a little surprised.
"Yes, it is too fast, because we have the most advanced computers in the world. The Tianhe computer used in our aerospace measurement and control center has the fastest computing power in the world."
"Tianhe?" Qin Tao was a little confused. Shouldn't it be Godson?
"Yes, this computer uses 6144 Loongson processors and 5120 GPUs developed by Loongson. However, the computer was developed by the National Defense University, not Loongson. They are only responsible for providing the processor. This
After the computer was developed, it was named Tianhe, and its computing speed is currently the highest in the world."
Although Qiongzhou also has advanced measurement and control equipment, when it comes to computing power, it is still stronger here in the capital. Such powerful computers have been moved out! "As for the computing power, it has a peak speed of 1206 trillion times per second.
, that is, quadrillion times. Currently, there is only this one in the world."
If you want strong computing power, you need multiple processors. This world's number one computer has more than 6,000 processors packed into it, and it certainly occupies a large area.
"Isn't it huge?"
"Yes, it occupies one floor and has a total weight of 155 tons. However, after it was completed, it played an important role in all aspects. It is used by our measurement and control center at critical times to monitor space launches. It can be used by other brother units in normal times.
, whether it’s weather forecasting or numerical calculations, they are all top-notch.” Jiang Weixing continued.
Qin Tao is very proud. Through his own promotion, his motherland has become the first in the world in all aspects. In terms of super computers, the outside world cannot even think of surpassing him!
The fast computing speed of supercomputers has made many impossible possibilities possible. For example, the development of nuclear weapons used to have to be built and tested to see how effective it was. But now? It is completely possible to write programs and perform nuclear tests on the computer again and again.
It explodes, it won't pollute the environment, it won't waste a lot of money, it's silent, and no one knows.
As Qin Tao was sighing, the measurement and control signals had been launched into the sky through the Yuanwang space measurement and control ship, passed through the vast universe, and were sent to the lunar relay satellite, and then sent to the orbital module and lunar module.
This takes time. After all, the distance is too far, and electromagnetic waves also take time. However, relying on the navigation satellites on the lunar surface, the orbiting module and the lunar module can obtain precise timing services, so as to know when to change orbit.
, guaranteeing that there won’t be any accidents.
This is also another use of navigation satellites. After all, the premise of navigation is to obtain accurate time.
In the orbital cabin, Carlos was full of excitement.
All of this was like a dream. He signed up with the Starship Company and asked to buy the first ticket to set foot on the moon. He was selected among dozens of competitors, and then started various trainings before taking off and leaving the earth.
, heading to the moon.
According to the time, he should rest now, but in space, he couldn't sleep at all. He picked up a bag of space food, fish-flavored shredded pork rice bowl, and slowly squeezed it out.
Training is necessary, mainly focusing on daily life, how to eat, and how to use the toilet. If these are messed up, the entire living cabin may be messed up, and the aircraft may even have to return early because of the poor environment.
He also fell in love with oriental food, especially fish-flavored shredded pork. Although there was no fish in it, it was given such a name. He once asked about it, and the answer he got was even more confusing. There is no fish in the wife's cake.
My wife, is it normal that there is no fish in the fish-flavored shredded pork?
Now, just as he was enjoying his third bite, the camera suddenly focused on him, and then a voice sounded: "Mr. Carlos, are you ready? The live broadcast is about to start again."
"It's done, just in time for the whole world to see how I live in space, especially eating. I'll show you... Oh, no!"
Carlos exclaimed. Just as he was looking at the camera, he unknowingly squeezed out another piece of fish-flavored pork rice bowl, but his mouth was not nearby, so the piece of fish-flavored pork rice bowl came out.
Just fly!
This would not work, something big would happen. He was startled, so he wanted to chase him, but he forgot that he was in space, and his body left the handle and was out of control. So he could only use extremely weird postures to chase
before swimming.
The camera was turned over and the whole world saw such a strange scene.
Carlos was swimming in the orbital module! He was actually swimming in the air! While swimming, he encountered a piece of... fish-flavored shredded pork rice bowl, and then ate it in his mouth!
It's that simple, it's that fun!
Carlos is indeed responsible for the fun!
All the viewers watching the live broadcast couldn't help but want to laugh. It was so weird. This scene was simply unbelievable!
The key thing is that after Carlos finished eating this piece, more fish-flavored pork shreds were about to spill out of his bag!
At this moment, Pan Chun came over. He jumped from the handle of the bulkhead, and with the help of inertia, he rushed to Carlos's side, grabbed the bag, and then went to the other side and fixed it on the side wall.
"Mr. Carlos, let's get back to our seats. We are about to dock, and we may change our posture."
"Okay." Carlos nodded, then looked at the camera: "Wait a moment, everyone, I'm going to eat space meals in my seat. It feels completely different from eating on the ground. I think anyone who has the ability should go to space to experience it!"
Space docking allows two spacecraft in space to be connected together to achieve more functions. Whether it is personnel transfer, formation of a combination, maintenance, etc., this method is required.
Historically, in 1966, Armstrong and Scott took the Gemini 8 spacecraft and manually docked with the Agena target aircraft in space, thus achieving the first spacecraft completion in human history.
first rendezvous and docking.
Although Armstrong is famous for being the first to step on the moon, in fact, he also made many other firsts, and this rendezvous and docking is one of them.
This is also necessary. After all, if he wants to land on the moon and return, he must dock the lunar module with the Apollo spacecraft. If he does not have this ability, he will never come back.
Lao Maozi was not to be outdone. In 1969, Soyuz 4 and Soyuz 5 successfully docked, thus realizing the docking of two manned spacecraft in space. Moreover, the astronauts of Soyuz 5 also visited Soyuz 4 as guests.
Dongfang's rendezvous and docking technology is not very old. It began to explore rendezvous and docking only after the development of manned spaceflight. However, due to the rapid development of electronic technology, Dongfang's rendezvous and docking success rate has been greatly improved, and there are many advanced aspects.
For example, the entire interchange and docking does not require humans to operate at all. It is completely automatic and you only need to wait.
Zhao Dong is the commander of this mission, that is, the top leader. He was flipping through the command documents on his seat, waiting for various data messages on the big screen in front of him.
Time passes very slowly.
Countless people on Earth are also waiting. The success of this docking is directly related to whether the moon landing can be carried out. During the live broadcast, they even saw Carlos' wonderful performance.
Carlos seemed to have adapted to life in space. He happily ate the shredded fish-flavored pork on his seat. After successfully eating a few bites, he started to do another trick: he poured out another strip of shredded fish-flavored pork.
Come, fall down and float in the space in front of him, then stretch out your mouth and eat the shredded meat into your mouth.
"Have you all seen it? It's like performing a magic trick. By the way, I'm thirsty and I need a sip of water."
Carlos poured the water in front of him. It was completely weightless in space, and the water took on an absolutely spherical shape. Carlos continued to put his mouth over, trying to suck the water ball into his mouth, but at this moment, the spacecraft suddenly shook, and then,
All the water droplets hit his face.
Carlos wiped it with his hand and said calmly: "Everyone, I was just showing you how to wash your face in space."
This guy is really here to be funny!
Zhang Zhong, who was in charge of the commentary, seldom interrupted. He watched Carlos bring laughter to the audience in front of the TV. It is very expensive to broadcast these pictures in space. After all, one has to rent a video channel of the communication satellite. However, this ratings
The profit margin is absolutely leveraged, and the stock price of Starship Company is also rising sharply with this launch. They have a lot of money.
"Okay, dear viewers, let's switch the video. Now, from the perspective of the lunar module, the orbital module is slowly approaching and the docking is in progress."
There is a camera outside the lunar module that can take pictures of space. Since the lunar module is facing away from the sun, it can take a clear picture of the orbital module facing the sun.
The thrilling space docking is about to begin!
"We can vividly compare space docking to threading a needle thousands of miles away. The technical difficulty is quite high. If you have basic knowledge of physics, you will know that you can catch up with the spacecraft in front without accelerating. When accelerating, the spacecraft will
The spacecraft will undergo centrifugal motion, which may make it farther and farther away from the target. It is necessary to accurately adjust the orbit of the spacecraft to conduct correct rendezvous and docking. Even in the earth orbit, there are various precise measuring instruments for rendezvous and docking.
Docking would also be difficult, let alone on the moon."
As Zhang Zhong explained, the two spacecrafts were getting closer and closer. At this moment, suddenly, the orbital module turned into two shadows!
The shadow above was very big and the light intensity was very strong. The shadow below was only one-third of the size of the one above and was still very weak. This shot appeared on TV screens all over the world and instantly shocked everyone.
.
"This is a rare spectacle. The glare creates a virtual image. Audiences with photography experience should be familiar with it. One of them is a ghost image." Zhang Zhong continued: "Now, it depends on the performance of our technical team.
Analyzes."
Ghost, during the rendezvous and docking in the lunar orbit, we actually encountered a ghost!
Everyone in the Capital Measurement and Control Center became nervous. One of these two shadows was fake, but how to tell the difference?
At this moment, Max said firmly: "Don't worry, our system will adjust itself."
Automatic dimming!
Since it is an optical phenomenon, the problem can be solved optically! Max believes that the system he developed has this ability!
Sure enough, the camera lens began to slowly adjust the light. With the adjustment, the originally strongest shadow slowly disappeared, and the originally weak shadow began to slowly enlarge, and finally turned into the outline of the orbital module.
"Great, this is the product of the most advanced Starship Company in the world. After encountering a ghost, it can quickly solve the problem by adjusting itself and separate Li Kui and Li Gui. Our Starship Company is the strongest
"!" Zhang Zhong was very excited at this moment. As a commentator, he was also proud of the strength of Starship Company.
Countless people watched this scene in front of the TV, and they were all shocked.
NASA.
"We also encountered two ghost images during space docking." A technician said: "At that time, our solution was to continue flying. After about half an hour, as the position changed, this optical phenomenon
It will disappear. Unexpectedly, the Easterners solved the problem easily!"
"It's not the Orientals, it's the Starship Company, which has a large number of NASA technicians! Those advanced technologies must have been developed by NASA personnel, and we are the best!"
"That's right, their starship company is just standing on the shoulders of giants. Orientals don't have these capabilities at all."
All NASA has left is this self-comfort.
In the Dongfang Measurement and Control Center, Qin Tao also looked at Max curiously: "How is this program solved?"
"It goes without saying that since our navigation satellites have an accuracy of less than one meter, false targets can of course be identified immediately and then filtered out using programs."
Docking is very complicated. The guidance process can be achieved with radar, but the accuracy of radar is not enough. This is somewhat similar to the automatic landing assist system of carrier-based aircraft. Guidance radar always faces the problem of insufficient accuracy.
What is more accurate than radar is, of course, the satellite navigation system. A high-precision satellite navigation system can achieve a resolution of less than 0.1 meters, so that you can accurately know your position.
As for docking in space, the accuracy is improved with the help of satellite navigation systems.
In later generations, when Dongfang was engaged in space docking, it often had to fly in space for a day or two and constantly adjust its orbit before docking successfully. When the Beidou navigation system was developed, the docking time was greatly shortened, especially in 2022.
The cargo spacecraft docked in autonomous mode and successfully achieved a two-hour rapid rendezvous and docking.
Prior to this, Lao Maozi's Alliance MS-17 spacecraft maintained a record of 3 hours and 3 minutes, but Dongfang has refreshed this record. It can be docked within two hours of launch, which can greatly save the time of transportation between heaven and earth.
time.
The satellite navigation system plays an important role. Now on the moon, with an accurate satellite navigation system, docking can be made so easy.
The distance between the two spacecrafts continues to get closer, making final contact.
No matter how precise they are, the two spacecraft will not be accurately aligned in space. So if you want to dock together easily, how to solve the final handle problem?
Lao Maozi's plan is to extend a cone rod, and there is an arc-shaped chute on the docking spacecraft, which is somewhat like a bowl. When the cone rod is poked up, it will slide inside the bowl and eventually poke all the way to the bottom of the bowl.
In this hole, they can be connected together. The whole process is simple and crude, with Lao Maozi's usual style.
The United States uses a heterogeneous and isomorphic peripheral docking scheme. This scheme has been used since the era of Apollo rockets and space shuttles. It is divided into two steps: soft docking and hard docking. Soft docking is performed first.
Many of Starship's technologies come from NASA, and the docking solutions are the same.
At this time, the cover on the top of the orbital module has been flipped open, revealing the docking mechanism inside. The three guide petals look clearly to the spacecraft, and can be clearly seen from the lunar module. Finally, these occupy the entire field of view.
A slight vibration came, it was already connected!
After the soft docking is successful, the bumping buckle of the bump lock is buckled and the position is completely aligned. Then the hard docking ring makes precise contact, and the 12 sets of hard docking hooks and 3 sets of hard docking pins complete the locking.
