Rebirth of science and technology academic master

China is becoming more and more confident now.

Therefore, the Chang'e-4 probe has always had a live broadcast room, and will even conduct live TV broadcasts at key nodes, such as the launch of the Chang'e-4 probe, the migration of the Earth and the moon, braking in recent months, and orbiting the moon. These key nodes , all broadcast live directly on CCTV.

The live broadcast room is mainly for Internet users to watch.

Therefore, regarding the Chang'e-4 detector, the news is very hot and often grabs the headlines. In contrast, during this period, the exposure of celebrities has been greatly reduced. After all, whether it is the big news at the beginning of the month or the celebrations in the middle of the month Neither the Grand Hall nor the Chang'e-4 launch at the end of December can be compared with celebrities or the entertainment industry, and they are not on the same level.

The entire month of December, also known as the black month in the entertainment industry, was so miserable that even if celebrities deliberately spread scandals, they would not make the headlines.

"How magnificent! I am the Great China!"

"I think back then, when the Shenzhou 5 was the first manned spaceflight, I was so excited that I didn't sleep all night. But now that we have launched the Chang'e 4 to explore the moon, it's incredible to think about it!"

"The Earth-to-Moon migration route of Chang'e-4 is so beautiful. I have never seen such a beautiful Earth-to-Moon migration route. It saves a lot of time than before!"

"Unlike Chang'e-3, Chang'e-4's orbit is quite different. It orbits the moon from different angles and transmits photos of the moon back to the earth, allowing us to understand the moon better!"

"It's incredible. The two relay satellites provide information at all times and form a communication network with the communication satellites orbiting the earth. The signal delay is only three seconds. Who else can achieve this feat?"

"What is there to be proud of about a lunar probe? The United States has manned manned landings on the moon half a century ago, and more than once. They have space shuttles, but now we can only use spacecraft. The United States has all probes to explore Mars. The probes are about to fly out of the solar system. You guys are so superficial!"

"Since you look down on China so much, why don't you leave? Go be your American!"

"."

News about the Chang'e-4 detector can be seen everywhere on the Internet. On WeChat, Weibo, Bilibili, Zhihu, Douyin and other platforms, there are either short videos of Chang'e-4, or UP hosts analyzing various The link and the technology contained in it include the analysis of Chang'e 4 and the differences between this time Chang'e 4 and Chang'e 3. On Zhihu, it is also in the top ten of the hot search list, and its popularity remains high.

"I'm so sorry. Didn't NASA announce that it will return to the moon? Why hasn't it happened yet? Could it be that NASA has wasted taxpayers' money?"

"Why was NASA able to manned a manned moon landing half a century ago, but not now!? Is it really like the legend that it was not a real manned moon landing, but was just completed in a Hollywood studio?"

“Why, as one of God’s chosen people, would I be jealous of the Chinese?”

"I have decided to join the team and make purchases for zero yuan!"

"."

There are also heated discussions on Facebook and Twitter overseas. After all, China has made achievements one after another in these years, which is really unsettling. Watching China complete the lunar exploration phase and the space station has been initially completed, while the International Space Station continues to During maintenance, the service life is coming to an end. At that time, we will face the dilemma of not using the space station. And building a brand new space station cannot be completed overnight. The result is that NASA has to cooperate with the China Space Administration. Temporarily use China’s Tiangong Space Station!

How can the Americans, who have always been extremely arrogant and arrogant, accept this? After all, they are the world's hegemon and they will fight whoever they say.

However, if we want to build a space station, it will not be possible within ten years. After all, the space station is a complex system composed of many interrelated subsystems. A fully functional space station usually needs to have 10 modules, namely the main structure, power supply system, temperature control system, posture control system, orbital operation and propulsion system, automation and robotic systems, computer and communications systems, environmental and life support systems, crew accommodation facilities, and crew and cargo transportation systems.

The fourth-generation space station, like the International Space Station, is developed by NASA, the Russian Space Agency, and the European Space Agency. An international cooperation plan jointly promoted by six space agencies: Japan Aerospace Research and Development Agency, Maple Leaf National Space Agency, and Brazilian Space Agency. A total of 16 countries or regions participated in the plan, with a total cost of 160 billion US dollars!

Such an expensive investment cannot even be afforded by the United States, which has extremely high military expenditures and rich financial resources!

Qin Yuanqing also laughed off the heated discussions from the outside world. Now China is accelerating the layout of its aerospace engineering. Beidou Navigation now occupies a market share that is comparable to that of GPS. It is fully capable of global navigation. In addition, China is also a major smartphone manufacturing country. More than 70% of the world's smartphones are manufactured in China, which means that 70% of smartphones are equipped with the Beidou navigation system.

In addition, China is a major shipbuilding country and has the largest fleet. Naturally, it is also equipped with the Beidou navigation system.

China has also launched communication satellites, meteorological satellites, earth resource satellites, reconnaissance satellites, broadcast satellites, geodesic satellites, astronomical satellites, etc. one after another, forming a huge 'satellite family'. It is expected that in another five years, China's number of satellites in space will surpass that of the United States, becoming the country with the largest number of satellites in the world.

As for the space station, China is also accelerating its construction and is expected to complete its space station in 2020 or 2021. Through the accumulation of experience in Tiangong-1 and Tiangong-2, China has solved various space station technologies.

Moreover, compared with the past, the technical conditions have been greatly improved, and there are complete navigation systems and communication systems. By then, the space station will be able to communicate with the ground command center very conveniently. You can watch Chinese TV programs on the space station, and even video chat with your family. It's a breeze.

It can be said that China's technological development in recent years has also greatly promoted aerospace engineering. China's development is all-round, not just limited to one point, but all aspects!

On the day when the Chang'e-4 probe was about to orbit the moon and land on the moon, Qin Yuanqing also temporarily left Shuimu and came to the National Space Administration.

"Academician Qin, this is the detection data returned by Chang'e-4 in the past ten days. Take a look and see if there is any need to modify the relevant parameters!" The commander-in-chief said as soon as Qin Yuanqing arrived at the command center.

In the opinion of the commander-in-chief, Qin Yuanqing is more useful than a supercomputer. He believes in Qin Yuanqing's ability more than a supercomputer.

This time Chang'e-4 really surprised the commander-in-chief. He discovered that the Earth-Moon migration can be done in this way. It turned out that the optimal Earth-Moon orbit they calculated before was not the real optimal Earth-Moon orbit.

Qin Yuanqing looked at the relevant data and then looked at the topographic map of the far side of the moon taken by the Chang'e-4 probe. Qin Yuanqing took out an A4 paper, drew on it, listed the companies, and then frowned slightly.

"The landing point needs to be modified. I found that the increasing data is somewhat biased. Although it can make a soft landing, it is not the best landing point!" Qin Yuanqing said.

"Okay, Academician Qin, I will modify it as you say." said the commander-in-chief.

"Commander, is this too reckless? It is not appropriate to temporarily modify parameters and change the landing point." The chief designer of the Chang'e-4 detector frowned slightly.

"According to what Academician Qin said, we should believe Academician Qin!" the commander-in-chief said.

Others frowned. After all, it was taboo to make temporary modifications, and Qin Yuanqing had already said that it would not affect the soft landing on the back of the moon. Why modify it in this case?

"Follow Academician Qin's wishes!" At this moment, an old voice sounded, and it was Academician Sun who came in.

When others saw that it was Academician Sun, they immediately had no objections. This is Academician Sun's authority in aerospace engineering. It is the authority that he has established with a lifetime of hard work and continuous success. His personal prestige has exceeded the title of appointment.

Qin Yuanqing smiled slightly. His revised landing point, the planned landing position of the probe, was northwest of the Von Kármán impact crater.

Even if there is a certain deviation in the final landing position, the probe will not crash into a bunch of mountains in the southeast.

It can be said that the revised plan can achieve the accurate landing of the detector, has a high error tolerance rate, and is also conducive to Chang'e-4's detection activities on the back of the moon.

The modified parameters and new landing point were transmitted to Chang'e-4 through two relay satellites. Now, there is still an hour before Chang'e-4 achieves a soft landing on the back of the earth.

At this time, the soft landing of the Chang'e-4 probe also began to enter live TV time, and this live broadcast once again ushered in a wave of ratings climax.

"Attention of all departments, in half an hour, the Chang'e-4 probe will officially enter the moon landing stage. Please prepare in advance!"

"I repeat again, the Chang'e-4 probe will land on the moon in half an hour. All departments please report the status of the probe at any time to ensure that the moon landing process goes smoothly!"

In the command center, researchers and experts looked up one after another, with serious expressions on their faces.

As the countdown to the moonfall phase entered, the entire command center once again became extremely nervous and busy. The expressions on everyone's faces were tense, and they were devoted to their respective positions.

At the same time, the situation of the Chang'e-4 probe and the two relay stars were constantly reported to the command center. Everyone held their breath as the final 60-second countdown entered, looking forward to this moment.

This moment is so exciting. Either it will be a great success and receive countless applause and honors; or it will end in failure and all the hard work and efforts during this period will be in vain!

Whether the Chang'e-4 probe can be a complete success depends on this moment. Whether the second step of the lunar exploration project can come to a successful conclusion depends on this moment!

Audiences at home and abroad who are watching the Chang'e-4 probe land on the moon are also extremely excited and nervous. After all, the results will be announced soon!
