It's normal to develop some black technology in the future, right?

Chapter 401: The Problem You Just Can't Do

"Of course, in principle, the logic used by the Light Armor is the same as that used by NASA on the ground, but in terms of technical complexity, the technology of the Light Armor is much more difficult," Lin Jia quickly added.

If you downplay a technology too much, others will have no idea of ​​the value of what you have done.

Although most people can tell the clues just from the complicated painting process of this huge robotic arm, some people will inevitably misunderstand it, and under the distortion of foreign media, it is very likely that the essence of the matter will eventually become that Light Armor Aerospace stole NASA technology.

“I want to tell you that the difficulty of achieving thermal insulation coating in space is different from that on Earth.

I can even conclude that for a long time, the Light Armor will be the space station that exclusively possesses this technology.

Even if other institutions invest resources, they will not be able to achieve such a high degree of flexibility in space automated painting. "Lin Jia was not worried that the flag would be broken.

Chen Yuanguang took over the conversation: "That's right, because this not only requires a relatively powerful electronic control device to support it, it also has a very high requirement for the computing power of the space station itself.

I don't know if you are aware that in the past, whether it was the space station or the spacecraft, any aircraft that involved crossing the atmosphere and reaching the space environment, their built-in computer chips and storage devices were very basic versions.

In other words, the computing power that can be provided is extremely limited. This is because high-energy particles and cosmic rays are everywhere in space. Their existence causes space facilities to use overly advanced chips, which poses a high risk of failure.

The most common one should be the SEU effect, which is the so-called single event inversion. Simply put, it is the bit flipping of the storage unit due to space particle radiation, from 0 to 1, or from 1 to 0.

This can lead to incorrect calculation results, abnormal operation, or even system crashes. Such failures in the universe are terrifying. In the past, there have been many cases where satellites have failed due to the influence of high-energy charged particles in the Earth's radiation belt, causing the satellites to lose control and crash.

Due to the diversity of high-energy particles, it is difficult to have a single material that can shield the impact of all high-energy particles. Even adding anti-radiation plates to the components themselves may not necessarily have a good effect.

A small number of radiation particles may interact with the shield and produce secondary charged particles, which would make the situation even worse.

Guangjia Aerospace has solved this problem. The difference between the computing chips and communication components on board the Guangjia and traditional spacecraft can be said to be the same as the difference between a Ford car in the 60s and today's new energy domestic cars.

Even bigger.

The research and development of this system 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 and then build a high-computing cluster to provide fully automated services. "

The comments were all full of "awesome" comments. Chinese netizens were all posting comments. Those who had previously heard that the inspiration came from NASA and were worried that America would soon catch up, felt as refreshed as if they had drunk a can of iced Sprite in the summer after hearing that only China could do it and no one else could.

Apparently, those watching the Guangjia Spaceflight live broadcast were not only Chinese netizens, but also foreign audiences, as well as all foreign professionals whose work was related to aerospace. Without exception, they were all watching the live broadcast.

After hearing Chen Yuanguang's confidence, NASA Director Nelson frowned and said, "Elon, you have a good personal relationship with Wright. 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 consulted Wright, and he told me that the general solution adopted by the Light Armor is not composite metal, but magnetic field.

They created an active protective magnetic field to protect the electronic components in the aircraft.”

Nelson was shocked when he heard about the magnetic field. As a former astronaut and payload specialist, he participated in the Columbia space flight 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: "Another damn room-temperature superconductor?"

Musk nodded: "Yes, it is through the magnetic field constructed by superconductors, and then the magnetic field provides a protective barrier for electronic components."

Nelson was very clear about the use of magnetic fields for protection, because they had started related explorations in the 60s. However, because there were only low-temperature superconducting materials at the time, the conditions for forming superconductivity in the universe were very harsh, so the research was interrupted.

In 1993, NASA hired Professor Franklin Cook of Duke University to make a final report on magnetic field protection against solar radiation particles.

Since then, NASA's research in this area has been intermittent.

Because of the research on high-temperature superconducting materials and the Mars exploration plan, NASA began to restart the research. In addition to sponsoring American 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 the real name of this superconducting material.

They used superconducting materials to make a cylinder to form a closed loop, named it a magnetic lens, and found that this could protect against most high-energy particles.

After 2004, MIT also received some money from NAS to conduct related research. They used superconducting materials to build a layer of protective magnets outside the spacecraft, which they called a magnetic bubble.

These things happened a long time ago. The fundamental reason is that there has been no breakthrough in room-temperature superconductivity and energy technology. The cost-effectiveness of building a magnetic field in space to protect against high-energy particles is too low. Instead of spending a lot of effort to develop these flashy functions in space, it is better to do something practical.

Since no one can handle high-energy particles anyway, what's wrong with using outdated electronic components?

That’s right, when there was no room-temperature superconductivity, magnetic field protection was an unrealistic solution, but with the advent of room-temperature superconductors, the situation is completely different.

Magnetic field protection is not only feasible, but has also been proven by the Chinese, who use this technology in their latest space station.

"This is terrible news." Nelson felt that his heart was about to give out. He didn't know if it was because of his age or because the news was too exciting.

Musk's face was solemn: "It is indeed bad news."

He knew very well what it meant that China's aircraft and space stations could use high-performance chips and storage devices, which meant that the other side could use advanced algorithms and computing power support on a large scale, while they were still stuck in the last century. The difference between them was not the difference between a joint venture brand's fuel car and China's new energy car, but more accurately, the difference between the 18th century Ford T-class car and the current China's new energy car.

China's aircraft can perform various types of automatic driving, automatic docking, and can carry more automated functions.

Musk had never understood why it was unrealistic for Guangma Aerospace to train HBM robots just for use on the moon. Only the most basic robots can operate in the environment on the moon.

If you try to use an HBM computing robot on it, it will fail in two days.

Unexpectedly, the Chinese have mastered the anti-interference technology of space chips.

Among American's spacecraft, the most advanced chip used is the James Webb Telescope launched in 21. Its built-in CPU is the RAD2001 released in 750, with a 150nm process. It should be noted that even the world's most powerful James Webb Space Telescope launched in 2021 still uses the RAD750 chip, which was released in 2001 and has a process of only 150nm.

"No, the bad thing is that there has been too much research on superconductivity in the past, and the technological breakthroughs achieved by the Chinese in the field of room-temperature superconductivity have allowed them to dig up treasures from past superconducting applications.

And we can only watch them dig out the treasure from it and can't do anything.

This is true for quantum computers, aerospace planes, and space stations. "Nelson said, "Oak Ridge and other research institutions get more than $50 billion from Congress every year just for room-temperature superconductivity. This project alone is $50 billion. Apart from proving how powerful the Chinese room-temperature superconductivity technology is, there has been no progress.

That’s what’s really frustrating.”

Musk hesitated, "From the beginning, I advised the president that instead of giving the money to Oak Ridge, it would be more reliable to give the money directly to *** and let them find a way to get the technology out of China."

Nelson 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 superconductor preparation process from the Chinese.

"Such a huge budget must be approved by Congress."

"Our annual military expenditure is more than $8000 billion, and it can be packaged into America's huge military budget as an undisclosed advanced weapons research and development project."

"But this will be exposed by the media sooner or later."

"Even if it was exposed, it was only after we got the key technical parameters and successfully reproduced room-temperature superconductivity in the American continent."

"Well, no matter what decision we make, we don't have much time left. If two-dimensional superconductivity is really related to artificial intelligence technology, no one knows how far the Chinese have progressed."

Although the live broadcast of the entire docking process between Changkong and Guangjia was only a short hour and a half, the discussion it aroused on the global Internet can definitely be called a historic event.

From radio to television to Internet text, and up to today's short videos, everyone can share their feelings with countless audiences through videos, which will undoubtedly amplify the popularity of the whole thing.

"Today's live broadcast really has too many highlights. The price of 500 million is definitely cheap enough. I asked my friends who are worth more than 1 million, and they generally responded that it was too cheap. They felt that for such a cutting-edge project, they were willing to pay a little more money to let Guangjia Aerospace make money, and everyone wanted the souvenir very much.

This means that a souvenir numbered 1 or with other special commemorative significance is likely to be worth more than a 500 million ticket.

Guangshen also set a record for Douyin. 500 service products worth 500 million, or 25 billion, were sold in just one second. This is truly a one-second sale.

Guang Shen is indeed a god, in every sense of the word. I think he can become the best seller even if he does live streaming. After watching the sales at the beginning and the tickets sold out in a second, I wondered why Guang Jia Aerospace didn’t do a clothing collaboration like NASA did.

Not to mention anything else, even if it's just a white T-shirt with a logo printed on it, and it's sold for 328 in China, I'm sure it will be a hot seller. It can be used in all kinds of collaborations, such as clothing, water bottles, and outdoor equipment. I can make a lot of money just by collecting licensing fees.

I'm also a little curious, because it's a deposit, and 500 million is not a small amount. I'm curious whether Douyin got a cut from it.

But I don't think so. Boss Zhang won't do it in such a short time. It's not just Douyin that can make the deal. If Guangjia Aerospace is willing, they would be willing to do such a live broadcast no matter if it is switched to Taobao or JD.com, even if they have to pay money.

Ultimately, technology is the primary productive force. In the past, there were people who were able to deliver commercial spaceflight. Many foreign companies were working on this project, and the prices were very high, often tens of millions of dollars.

The earliest Virgin Airlines, and later SpaceX, Blue Origin, and Orbital Space, these companies are all engaged in space travel, but their delivery capabilities are all in the double digits. Even SpaceX's annual deliveries are only in the double digits.

One reason is that there are only so many wealthy people who can afford to pay so much money and are willing to do so. The other reason is that there is their service carrying capacity. To put it bluntly, the rocket production capacity is limited.

Now that the space shuttle has come out, there are 500 of them a year, but this is because the space station is limited in size, not in its carrying capacity.

In my opinion, the price of 500 million is very appropriate. Although Tiangong cannot recover its costs, building another one will definitely cost less than a few hundred billion RMB. Ten billion at most will be enough.

Investing 10 billion to build another Tiangong, and then spending 5 million US dollars to target the global market, this business is definitely profitable.

I estimate that in the future, low-Earth orbit will not be considered space, because it is too easy for people to go there. If you ask wealthy people, 5 out of will say they have been there.

In addition, this is also the best advertisement for the Changkong space plane. No matter who you choose or which platform you use to place the advertisement, it will not be as good as this one.

We first went to the International Space Station, then went to the Light Armor, and were just short of going to the moon. After a round, we brought back the astronauts from the International Space Station without any problems.

Now no passenger will question its safety. If it can go into space, is there any problem with flying on Earth?

I estimate that the promotion speed of Changkong as a long-distance passenger aircraft will be much faster than we originally thought. "
