Wealth

　　 Before dinner, Fan Wuyi went to the scene again to take a look at the scene and condolences to Maximus, Harry Ford and others who were sticking to their posts. Of course, he didn't send a check to everyone this time.

　　 Lao Tzu is not a big head either, always pay attention to return when paying out. Now that the purpose has been achieved, there is no need to waste it. After all, my money is not easy to come by.

Fan Wubing circled the satellite twice again. Everyone felt better about him this time. After all, the saying was good. The man who eats people is the softest. The man’s hands are short. Foreigners also recognize this. set.

Even this time, Harry Ford not only showed him the effect of the special satellite surface paint printed on the real object, but also asked him to put on a set of staff-specific clothing and personally touched his satellite. .

Although there is still a layer of gloves, Fan Wubing finally touched his satellite. It feels hard and cold. Originally, Fan Wubing wanted to reach out and knock on it with **** and listen to it. Listening to the sound, Harry Ford hurriedly stopped him.

　　 "Fan, this is not a watermelon!" Maximus also broke out in a cold sweat.

　　 It goes without saying that Fan Wuyi’s Snap Fingers will cause permanent damage to the physical structure of the satellite’s surface. Judging from the technical content of the satellite’s surface, this is definitely not as simple as a thin steel plate.

For example, the electrostatic treatment technology on the surface of satellites is a small and important project. In the early days of space technology research, many scientists had predicted that the surface potential on rockets and low-orbit satellites would be between a few tenths and a few volts, but According to estimates, this low surface potential will not adversely affect the normal operation of the satellite.

　　 In fact, before the end of the 1960s, most scientists and engineers denied the possibility that the space environment could cause the surface of the satellite to be charged and even cause damage to the satellite. But by the early 1970s, many satellites in the synchronous orbit of the United States had abnormal phenomena.

　　 In order to explain the cause of this abnormality, a lot of research and experiment work was done abroad until after 1972. Scientists have continuously observed the occurrence of satellite anomalies and magnetospheric substorms. There is an accurate connection in time and space, and they have concluded that the space environment, especially magnetospheric substorms, may charge the satellite surface to thousands to tens of thousands. Volt’s conclusion.

　　 In this case, there will be targeted treatment, so on the satellite surface materials and related equipment structure. The Hughes Company has put a lot of effort into it. How dare Fan Wubing play with such a delicate thing like knocking on a watermelon?

　　 Fan Wuyi smiled and said. "I thought this thing should be very strong."

　　Maximos didn't dare to let Fan Wuyi hang around here again. He immediately took off Fan Wu's uniform from his body, and then drove him outside, ordering him to observe from a distance only 20 meters away.

　　 The observation of an "employee" who was placed under Fan Wubing's hands at this time came to an end. Seeing this scene just now, I couldn’t help but smiled and said to Fan Wubing, “Satellites are relatively fragile things, especially on its surface. Not only do they have to withstand the test of high temperature and low temperature, but also face the possibility of sudden arrival. Although we have all used various methods to avoid this kind of damage from the impact of the cosmic dust, objectively speaking. To a large extent, everything depends on luck."

　　 "Oh, I know this." When Fan Wubing heard this expert say, he remembered the news reports he had seen before.

　　 The biggest natural enemy of communication satellites is not necessarily cosmic dust, but space junk.

　　 Since October 1957, the former Soviet Union launched the first artificial satellite. There have been more than 5,000 launches worldwide. Tens of thousands of man-made objects have been sent into space one after another, while human beings enjoy all the conveniences brought about by the use of space. It also turns the Earth’s near-Earth space into a huge garbage dump, with everything from discarded carrier rocket components, satellite ground fragments to astronauts’ lost ground tools, etc. The total weight is estimated to have exceeded 3,000 tons.

The biggest source of space junk is the debris of the rocket stuck in orbit. During the process of sending the satellite into the orbit, the rocket body of the launch vehicle will be separated from each other in stages. After the third stage puts the spacecraft into a predetermined orbit, it may float in space for a long time together with small objects such as blasting bolts and ejection springs generated during separation. The wreckage of the rocket body is relatively large and relatively easy to monitor, so it can prevent problems before they happen. But the problem is that they themselves may collide, burst or disintegrate in space, producing millions of fragments offspring, causing more trouble.

　　 According to statistics, the most prominent space collision incident in history is the wreckage of the Ariane rocket. In 1986, the Ariane rocket exploded shortly after entering orbit, releasing a large amount of debris and small fragments. Later, these wreckages and small fragments caused the death of two Japanese communication satellites and one French satellite in the process of orbiting the earth.

The expert nodded and said to Fan Wuyao, "Abandoned spacecraft are also an important source of space junk. Humans have sent about 5,000 spacecraft into space, but only about 800 are still working normally. Although most of them are still working. Spacecraft will fall into the atmosphere and burn out due to atmospheric drag. However, after reaching the end of its working life, spacecraft with a higher orbit will lose control and wander aimlessly in space. These abandoned spacecraft may still The explosion and disintegration due to collisions, structural aging, rupture of fuel tanks, etc. resulted in more debris. Of course, the spacecraft produced space junk may also be caused by man-made actions, such as the United States and the Soviet Union in the 1970s. In the 1980s, more than a dozen space weapon experiments were conducted, which destroyed dozens of target stars and produced a large amount of space junk.

　　 In addition, when astronauts are working in space, they also abandon or accidentally lose some things to produce space junk. For example, in 1965, astronaut Ed White of the Gemini 4 spacecraft lost a glove when he was on a spacewalk. Currently, astronauts have been banned from abandoning solid objects in space. "

　　 Fan Wuyi rubbed his nose and smiled bitterly, "All in all, the satellite I bought for hundreds of millions of dollars is destined to become a pile of space junk."

The expert laughed and said, "Small space junk can cause pits and scars on the surface of the spacecraft, and severely can cause induced discharge of internal sensitive components. Larger ones can cause structural damage to the spacecraft. Of course, damaged ones. The degree has a certain relationship with the location of the collision, the characteristics of the system design, and the protective measures adopted."

Maximus interrupted and said, "Our Hughes products are basically able to last until the end of the design life. This can be confirmed by previous data. If it is not too bad luck. I promise you satellites. It can last for fifteen years."

Fan Wubing shook his head and said, "This kind of guarantee of no pain or itching is of no practical significance to me. However. Generally speaking. What is the probability of a satellite being hit on the ground? I really don't want hundreds of millions of dollars to hear. The noise will be reimbursed."

The expert thought for a while and said, "According to relevant data, the probability of a catastrophic collision event for each spacecraft in space orbit is about 3%. The probability of a non-catastrophic collision event is as high as 100%. Twenty. So, the probability of your satellite being hit is also very high, especially the Hughes communications satellites are relatively large, and the targets are obvious, ha ha."

　　 "Uh----" Fan Wuyi stroked his forehead in pain.

　　 Anyone who heard that he had spent hundreds of millions of dollars to buy satellites might be crashed into a pile of rubbish, his heart would not be very happy, especially a nouveau riche who bought three satellites.

　　 But before Fan Wubing was here to blame himself for a long time, He Yun ran over. The complexion doesn't seem to be very good.

　　 "What's the matter with you?" Fan Wuyao immediately found out that it was wrong, so he asked in a low voice.

　　 He Yun shook his head and motioned for him to speak in another place.

　　 So Fan Wubing left the scene with He Yun, and the two returned to the small conference room.

　　Fan Wuyi found out that a double post had been added outside the door. After entering the room, he saw that the executives of the base were all there, all with serious expressions. The atmosphere is extremely tense.

　　Because it is a big customer. Therefore, Fan Wubing's seat was arranged in a very prominent position, which made Fan Wubing very proud. Because he was surrounded by stars shining with golden light, but everyone in the room looked solemn, which made Fan Wuyi feel very uncomfortable.

And He Yun is no longer qualified to sit down. She can only stand behind Fan Wuyi. She is regarded as an entourage. In fact, for her, it is already a great honor to be able to attend this kind of meeting at the lowest level of major-general. , You must know that although her military rank is not low, she is limited to her age, and she is only a major. Normally, there is no such opportunity.

　　 Fan Wuyi looked around, and suddenly found a problem, that is, the base commander looks a little like He Yun, he couldn't help but be a little curious. Could they be relatives? Looking back, he found that He Yun was standing like that, feeling a little sad, so he moved his buttocks halfway out, then patted half of the chair that was free, and motioned to He Yun to let her sit down next to him.

　　 He Yun was dumbfounded by Fan Wu's pupil's expression. He smiled and shook his head. In fact, he didn't find a chair, but in this kind of occasion, he really didn't have the qualifications to sit on his own.

　　 But Fan Wubing was able to make such a gesture, and He Yun still felt warm in his heart. Although this guy occasionally looked like a nouveau riche, he knew that he was sympathetic to his subordinates.

　　 Well, I am now his subordinate.

In fact, everyone is more interested in Fan Wubing. Many people are secretly looking at this young super rich man, especially when he heard that this guy came over and destroyed the base’s most hopeful Lieutenant Colonel Du Pengfei. Moreover, the collapse of Lieutenant General Han Zhizhong seems to have something to do with him. Everyone is a little jealous of him. Could it be that this is a broom star?

　　 Therefore, after seeing Fan Wu's child-like movements, everyone was a little surprised and all smiled. He Yun also noticed that everyone was looking here, and his face was a little red, but Fan Wubing seemed to be clueless. He winked at himself, insisting to let himself sit with him.

The base commander’s expression was quite embarrassing. He coughed and wanted to say something, but the admiral next to him also saw the situation here and said with a smile, "Hehe, Major He Yun, Since Boss Fan doesn’t mind squeezing with you. Then you can do it. Because it is the Standing Committee, there are no extra chairs. You two will make do with it first, and we will report the latest situation now."

　　 Although the Admiral had spoken, He Yun was still a little nervous in his heart. She glanced at the base commander, a little afraid to sit down.

　　 The commander of the base coughed, "The chief has said everything. You just sit down. What do I do?"

Admiral 　　 smiled, "You two, father and daughter, really. Haha."

"Is he your dad?" Fan Wubing asked He Yun, who had just sat down next to him. He nodded when she saw her. "No wonder I think the two of you look a bit similar. I thought it was. Where is your relatives, but I didn’t expect the commander of the base to be your father."

　　 Corruption, there is absolutely suspicion of corruption!

　　Fan Wubing not only sighed secretly, he had only arrived at the base for a few days. I met He Yun, Han Chang, and Du Pengfei. They were all military children. After Du Pengfei was an orphan of a martyr, He Yun and Han Chang’s father were both lieutenants in the base, and Du Pengfei was more likely to become Han Chang's husband, speaking of it, are the children of high-ranking cadres. Moreover, the military ranks are much higher than those of ordinary officers. Can't you doubt that there is nothing tricky in this?

　　 However, it is obvious that Fan Wubing doesn't have much time to care about this issue. A word from the commander of the base mobilized everyone's emotions.

"Comrades, I have an update to inform you." The commander of the base opened a folder, and then said to everyone, "According to a temporary notice from the superior, the head of No. 1 will come to the site to inspect the work on the day of the satellite launch. ."

Ah? ! Once the news was announced, everyone in the house couldn't hold back.

　　 The No. 1 chief came to the scene in person. This is not something that happens all the time. It is enough to show that the superiors care about and value our work! Among the four major launch bases in the country, our Jiuquan base is considered to be a time-honored one. Now it is the first time to accept an international satellite launch mission. It is about to open an important juncture in the international market. Morale is a great stimulus for everyone's enthusiasm for work.

　　 Therefore, after the base commander finished speaking, all the people present immediately overflowed with bright smiles. I wish I could see Chief No. 1 immediately and listen to his old man's sage teaching.

Uh? Fan Wubing was also very surprised, but his more thoughts were that this time he could take a group photo with Chief One, and then it would be a large photo and hung on the living room wall of his home to receive guests. Isn’t that a very face-to-face thing when it’s time?

　　 Thinking of this, Fan Wuyao couldn't help but laughed. He Yun saw him next to him. He suddenly felt that Fan Wuyao's appearance at this time was a bit wretched. At first sight, he was making bad ideas in his stomach, and he couldn't help but snorted coldly.

"It's a big accident that the commander of No. 1 was able to come and guide in person." The commander of the base waved his hand to signal everyone to be quiet, and then continued, "After receiving the notice from the superior, we also sent a message back from the launch site. , Which also surprised us."

　　 There is a second accident? Not only Fan Wubing~www.wuxiaspot.com~ others are also taken aback.

The base commander frowned and said, "The launch is about to happen the day after tomorrow, but there was news from the launch site just now that during the last inspection of the rocket, an abnormal level was found. In other words, if the source of the problem is not found, I'm afraid it will be impossible to launch on time."

Ah? ! Everyone was stunned right now!

Chief No. 1 came to watch the launch process. It was obviously an accident, and it was indeed pleasant. The abnormal detection of the rocket was another accident. Obviously this was shocking. The two news came at the same time, which brought everyone. It feels a bit unclear whether it is surprise or joy.

　　 Of course, the most depressed person is Fan Wuyi. Don’t mention how awkward he is. The good news and the bad news come at the same time. What does it mean? At this time, he was really a little skeptical. Naturally, no one dared to make up the good news, but whether someone deliberately made up the bad news in order to show all the members of the base in the face of emergencies in front of Chief One. How strong is your coping ability?

　　 But thinking about it, this is unlikely, it seems that something really went wrong.

　　 Is this launch a bet? It's just that this dice cup is open or not?

　　 Ha ha, the second one is finally delivered. Tomorrow's first time is more likely to be in the afternoon, because it is obviously a delay in being notified to listen to the report in the morning. Little Wolf will continue to work **** the code, and strive to ensure that the 4D will be updated tomorrow. Then, continue to ask for monthly ticket support. Thanks! *
