Chapter 401 You just can’t solve the problem
"Of course, in principle, the logic used by Guangjia and NASA on the ground is the same, but from the perspective of technical complexity, Guangjia's technology is much more difficult." Lin Jia quickly added.
You describe a technology too lightly, and others will have no idea of the value of what you have done.
Although most people can see the clues just from the complex painting process of this huge robotic arm, some people cannot help but misunderstand it. Under the distortion of foreign media, the essence of the matter eventually becomes that the mecha aerospace steals NASA technology. Most likely.
“I want to tell you that the difficulty of applying thermal insulation layer coating in space is different from that on earth.
I can even conclude that for a long time, the Guangjia will be the space station that exclusively possesses this technology.
Even if other organizations invest resources, they will not be able to achieve such high flexibility in automated space painting. "Lin Jia is not worried at all that the flag will be broken.
Chen Yuanguang took over: "That's right, because it not only requires a relatively powerful electronic control device to support it, but it also has high requirements on the computing power of the space station itself.
I don’t know if you are aware that in the past, whether it was a space station or a spaceship, any aircraft that traveled through the atmosphere and entered the cosmic environment had very basic computer chips and storage devices built into them.
In other words, the computing power that can be provided is extremely limited. This is because of the ubiquitous high-energy particles and cosmic rays in space. Their presence causes space facilities to use overly advanced chips, with a high risk of failure.
The most common one should be the SEU effect, which is the so-called single-particle inversion. Simply put, the bit flip of the memory cell occurs due to space particle radiation, from 0 to 1, or from 1 to 0.
This may lead to incorrect calculation results, abnormal work, or even system crash. It is terrible to have such a failure in the universe. There have been many cases in the past where satellites malfunctioned due to the impact of high-energy charged particles in the Earth's radiation belts, causing the satellites to crash out of control.
Because of the diversity of high-energy particles, it is difficult to have a single material that can shield the effects of all high-energy particles. Even adding a radiation-resistant board to the component itself may not have a good effect.
A small number of radiation particles may interact with the protective layer and produce secondary charged particles, in which case the situation will be even worse.
Guangjia Aerospace has solved this problem. The difference between the computing chips and communication components carried on Guangjia and traditional spacecraft can be said to be the difference between Ford cars in the 1960s and current new energy domestically produced cars. Same.
Even bigger.
The development of this system itself is not complicated. I believe that whether it is NASA or other countries, they can definitely do it as long as they spend time and budget, but they will definitely not be able to install it in space.
Because they cannot shield high-energy particles in space, they can then build high-computing clusters to provide fully automated services. ”
The comments on the barrage are all awesome, and Chinese netizens are posting them. Chinese netizens who had heard that the inspiration came from NASA and were worried that Amerikan would soon catch up, now that they heard that only China can do it, After I couldn't do it abroad, I felt as good as drinking a can of Sprite with ice in the summer.
At this time, it is obvious that not only Chinese netizens are watching the live broadcast of Guangjia Aerospace, but also foreign audiences, as well as foreign professionals who are engaged in work and aerospace, are all watching the live broadcast without exception.
After hearing Chen Yuanguang's determination, NASA Administrator Nielsen frowned: "Elon, you and Wright have a good personal relationship. Do you know how they protect against high-energy particles in space? Wright invented a new composite Metal to achieve this? ”
Nelson subconsciously wondered if there was any new alloy that could completely protect against all high-energy particles.
Musk nodded: "Of course, I asked Wright for advice, and he told me that the general plan adopted by the Guangjia is not composite metal, but a magnetic field.
They constructed an active protective magnetic field to protect electronic components in the aircraft. ”
Nielsen was shocked to hear the magnetic field. As a former astronaut who became a payload expert, he participated in the Columbia space mission before entering politics.
After he became the director of NASA, combined with his own experience as an astronaut, he knew very well how the Chinese did it: "Damn room temperature superconducting again?"
Musk nodded: "Yes, it is a magnetic field constructed through superconductors, and then the magnetic field provides a protective barrier for electronic components."
Nielsen was very clear about the use of magnetic field protection because they began related explorations in the 1960s. However, because there were only low-temperature superconducting materials at that time, the conditions for the formation of superconductivity in the universe were very harsh, so the research was interrupted.
In 1993, NASA asked Professor Franklin Cook of Duke University to make a final report on magnetic field protection against solar radiation particles.
Later, NASA's research in this area has been intermittent.
Because of the proposal of high-temperature superconducting material research and the Mars exploration plan, NASA began to restart this research. In addition to sponsoring Amerikan scientists, it also sponsored Italian scientists to carry out related research.
The Italian project used a superconducting material called NbTi, which is a niobium-titanium superconducting alloy. This is not a joke, but this superconducting material is really called that.
They made a column of superconducting material to form a closed loop, named it a magnetic mirror, and found that this could protect most high-energy particles.
After 2004, MIT also took some money from NAS to do related research. They used superconducting materials to build a layer of protective magnets outside the spacecraft. They called this a magnetic bubble. .
This is all a long time ago. The fundamental reason is that there has been no breakthrough in room-temperature superconductivity and no breakthrough in energy technology. The cost-effectiveness of constructing a magnetic field to protect high-energy particles in space is too low. Instead of spending great efforts to develop these flashy things in space Function, it is better to do something practical.
Since everyone can’t handle high-energy particles anyway, what’s wrong with using outdated electronic components? It’s not like it can’t be used.
Yes, without room-temperature superconductors, magnetic field protection is an unrealistic solution, but with room-temperature superconductors, the situation is completely different.
Magnetic field protection is not only feasible, but has also been proven by the Chinese. Their latest space station utilizes this technology.
"It's really terrible news." Nielsen felt that his heart was a little unable to hold on. He didn't know whether it was because he was old or because the news was too exciting.
Musk's face was solemn: "It is indeed bad news."
He knows very well what it means that China's aircraft and space stations can use high-performance chips and storage devices, which means that the other side can use advanced algorithms and computing power support on a large scale, but they are still stuck in the last century. The difference between these is not the difference between the joint venture brand's fuel vehicles and Huaguo's new energy vehicles. To be more precise, it should be the Ford T-class car in the 18th century and the current Huaguo's new energy vehicles.
China's aircraft can be driven in various ways, automatically docked, and can carry more automated functions.
Musk had never understood before that it was too impractical for Light Armor Aerospace to train HBM robots just for use on the moon. Only the most basic robots can run in the environment on the moon.
If you try to use a computing robot like HBM to put it on top, it will be over in two days.
As a result, I did not expect that the Chinese had conquered the space chip anti-interference technology.
Among Amerikan's space vehicles, the most advanced chip used is the James Webb Telescope launched in 2021. Its built-in CPU is the RAD750 released in 2001, with a 150nm process. You must know that even the world's most powerful telescope launched in 2021 The chip used by the James Webb Space Telescope is still RAD750. This CPU was released in 2001 and its process is only 150nm.
"No, the bad thing is that there has been too much research on superconductivity in the past. The technological breakthroughs achieved by the Chinese in the field of room-temperature superconductivity have allowed them to mine treasures from past superconducting applications.
And we can do nothing but watch as they dig out treasures from them.
This is true for quantum computers, aerospace aircraft, and space stations. Nelson said: "Oak Ridge and other research institutions receive more than 5 billion U.S. dollars from Congress every year just for room temperature superconductivity. This project alone is 5 billion U.S. dollars. In addition to proving the Chinese people's room temperature superconducting technology, There is no progress other than how awesome it is.
That's the really frustrating thing. ”
Musk hesitated, "I have advised Mr. President from the beginning that instead of giving money to Oak Ridge, it would be more reliable to give money directly to *** and let them be responsible for finding ways to get the technology from China." Compose a little bit.”
Nielsen was silent. Everyone knew that this was the most effective method, but no one was sure that they could get the core parameters of the room-temperature superconducting preparation process from the Chinese.
“Such a huge budget must be approved by Congress.”
"Our annual military expenditure exceeds 800 billion US dollars, which can be packaged in Amerikan's huge military budget and packaged into an unspecified advanced weapons research and development project."
"But sooner or later this will be exposed by the media."
"Even if it was exposed, it only happened after we obtained the key technical parameters and successfully reproduced room-temperature superconductivity on the Amerikan continent."
"Well, no matter what decision we make, we don't have much time. If two-dimensional superconductivity is really related to artificial intelligence technology, no one knows where the Chinese people have progressed."
Although the entire docking process between Changkong and Guangjia was broadcast live for only one and a half hours, the discussion it caused on the global Internet is definitely a historic event.
From radio to television to text on the Internet, and now short videos, everyone can intuitively share their feelings with countless audiences through video, which will undoubtedly amplify the popularity of the whole thing.
"Today's live broadcast really has too many highlights. The price of 5 million is definitely cheap enough. I have asked my friends who are worth more than 100 million, and their general reaction is that it is too cheap. They feel that this kind of cutting-edge project, I am willing to pay more for Guangjia Aerospace, and then everyone wants the souvenir
In this way, if the souvenir number is 1 or has other special commemorative significance, it is likely to be worth more than the 5 million ticket.
Guangshen can be regarded as setting a record on Douyin. It only took one second to sell 500 service products worth 5 million, which is 2.5 billion. This is a real second.
Guangshen is indeed a god, a god in every sense of the word. I estimate that even if he does live streaming, he can be the top salesperson. After watching the sales at the beginning and the tickets disappearing every second, I was thinking Why doesn’t Guangjia Aerospace do a clothing co-branding? It's like co-branding with NASA.
Not to mention anything else, even if it's just a white T-shirt with a logo printed on it, it sells for 328 in China. I'm sure it will be a hit. It can be used in various co-brandings, including clothing, water bottles, and outdoor equipment. Just charging the licensing fee will make you feel uncomfortable. .
I'm also curious, because it's a deposit, and a deposit of 5 million is not a small number. I'm curious whether Douyin takes a commission from it.
But I don’t think so. Boss Zhang won’t do it in such a short period of time. It’s not just Douyin that can close the deal. If Guangjia Aerospace is willing, no matter if it is exchanged for a certain treasure or a certain thing, they will be willing to pay for such a live broadcast. .
In the final analysis, technology is the primary productive force. Commercial aerospace has been delivered by people in the past. Many foreign companies have done this project, and then priced it very high, often tens of millions of dollars.
The earliest Virgin Atlantic, and later SpaceX, Blue Origin, and Orbital Aerospace, these companies are all engaged in space travel, but their delivery capabilities are all in double digits. Even SpaceX's delivery per year is only double digits.
First, there are only so many wealthy people who can afford to pay so much money and have the desire to do so. Second, there is only so much service capacity. To put it bluntly, there is only so much rocket production capacity.
But now that aerospace planes have come out, there are 500 of them a year. This is still because of the limited size of the space station, not because of the limited carrying capacity.
In my opinion, the price of 5 million is very appropriate. Although Tiangong cannot recoup the cost, building another Tiangong will definitely cost less than several hundred billion RMB, and it can be completed at most 10 billion.
Spend 10 billion to build another Heavenly Palace, and then sell it to the global market with 5 million US dollars. This business is absolutely profitable.
In the future, I estimate that low-Earth orbit will no longer be considered space, because it is so convenient for people to go there. If you ask a group of wealthy people, 5 out of 10 people have been there.
In addition, this is also the best advertisement for the Changkong aerospace aircraft. No one or any platform you place it on can be as good as this advertisement.
We first went to the International Space Station, and then went to the Guangjia, just shy of going to the moon. After a round, we brought the astronauts from the International Space Station back without any problems.
Now no passengers will question its safety. It can go to space. Is there any problem with flying on the earth?
I estimate that the Chang Kong will be promoted as a long-haul airliner much faster than we originally thought. ”
