Foreword: Recently, Lin Baojun, the designer of the mainland's Beidou-3, said in an interview that "China's aerospace manufacturing parts cost more than nine million yuan, while the United States can handle it with a few hundred yuan", is the gap between China's space industry and the United States so big?
For this statement, the vast number of netizens in various countries expressed their disbelief, and a fierce discussion began around this sentence.
China's aerospace from Dongfanghong No. 1 to Shenzhou 16, this is undoubtedly not to show the world China's space, China's power, since the founding of New China in 1949, the mainland's space technology has developed rapidly, these achievements all highlight China's speed and technological breakthroughs.
China has developed so fast, so why is there such a big cost gap in a small part?
Why is America's space industry so advanced?
You know, during the Cold War, the Soviet Union and the United States engaged in a big outbreak of science and technology, without considering capital investment, when science and technology collided, the mainland's space industry was just beginning, at the point of being black in both eyes, who would have thought that in just a few decades, under the blockade of Western technology and under the sanctions of US hegemonism, we still walked out of our own space road
As early as the First and Second World Wars, the United States relied on constantly moving between countries and selling arms to make a fortune in the war, making the United States one of the few countries that gained benefits in the world's wars, making the United States the richest country in the world. Until now, the development funds of the United States in the space industry have also become rich since this time, and the rapid development of the US space industry has been made by throwing money and burning money.
Due to the needs of the war, the Air Force crushed the battlefield, the United States has built tens of thousands of airports at home, focusing on the development of aircraft that can be used in war, and it is still the country with the most airports in the world. During the Cold War, in order to fight the Soviet Union, the two huge economies did not stop for a day, racing against time to develop high-tech military weapons, and the aerospace industry also took a huge leap at this time.
The United States was the first country to launch an artificial satellite, and the United States was twelve years ahead of China in terms of the satellite project alone. For the United States, the space industry is more like a face project, like the Soviet Union sent cosmonaut Gagarin into space on April 12, 1961, and the United States rushed to launch its own Mercury only half a month later. There is also the Apollo moon landing program, which cost hundreds of billions of dollars, and sacrificed many astronauts in exchange for the moon landing, and at that time there were no conditions for detecting lunar materials, and the continent was different, the continent was more careful in the space industry, and began to study the space industry on the basis of a better life for the people, at that time, the mainland's space industry was in its infancy.
The United States dragged down the Soviet Union, the only one that could compete with it at that time, and then it was the only one that paid more attention to the development of space science and technology, and only reduced the investment in space science and technology after the 2008 financial crisis, but the use of the public-private partnership model made Musk and NASA cooperate, not only did not reduce the speed of space science and technology development but also saved national investment, but this is only a superficial phenomenon, everyone can see it
Coming to Musk and the wolf ambitions of the United States, the United States wants to consolidate its now shaky title of the world's number one power by dominating space, and the idea of American hegemony has been planted in their bones.
The development of the mainland's aerospace industry
We didn't establish the Aviation Industry Committee until 1956, which marked the beginning of China's space industry.
At this time, the mainland is in a stage where it has just won the war, internal worries and external troubles, there are still a group of enemies outside staring at us, and internally we must solve the problem of food and clothing for the people, but the mainland's economy has just recovered, and the capital investment in the aerospace industry cannot be compared with the United States and the Soviet Union.
After we had a good economy, when the Soviet Union collapsed and the United States significantly reduced its capital investment in the space industry, we caught up and used the struggle of countless staff in exchange for overtaking in the field of space industry, although it was not ahead in technology but also completed the historical accumulation from scratch.
From the Dongfanghong No. 1, which was made according to the gourd drawing scoop, to the Beidou satellite, which can now be completely independently developed, to show China's space power to the world.
What exactly is the cost difference in what parts are actually so large
This part is used in space computing space-grade chip motherboard, Tesla in the United States, the production of such a chip motherboard only needs hundreds of yuan, and in China the production of this chip is not smooth, as the mainland Beidou-3 satellite chief designer said reached more than nine million yuan, the same role we spend so much money why?
China's self-developed space-grade chips are very different from ordinary chips, space-grade products above the military level, working in the harsh environment of space, need to fight against a large number of high-energy particles and gamma rays in the universe, the radiation intensity of these rays is very high, to work in space, the requirements for the product are not generally strict, and such product production technology has long been blocked by Western powers, mainland researchers resisted great pressure to achieve corner overtaking on an unfamiliar track, Such results were made at a cost of only 9 million.
Mr. Lin Baojun, chief designer of Beidou Satellite, said that the price of more than 9 million yuan is several times cheaper than before. After that, our manufacturing prices will drop lower and lower, and in the near future, our Chinese intelligent manufacturing will shock the world.
Before that, the mainland was extremely dependent on imported space-grade chips, when the United States Xilinx company sold space-grade chips to 5 million yuan a piece, but at that time we had no way, in order to explore the aerospace industry, helpless import of Xilinx sky-high chips, now is different, in the US space agency NASA is declining today, the mainland's space industry is developing rapidly.
From the design drawings to the chip production, China's aerospace chips have completely mastered the sky-high price of 5 million chips purchased by Western countries without relying on imports
The mainland's space-grade chip is not as fast as Elon Musk's SpaceX rocket chip in computing power, but it is better in stability, and the important point is that the mainland's chip is completely self-developed, and the United States has dominated the aerospace chip industry for half a century. Our development scared the Western powers, and in order to suppress our scientific and technological development, Western countries began sanctions against us.
U.S. sanctions against Chinese companies
When Huawei's chip design catches up with the world giant Qualcomm, the United States began to suppress Chinese companies, many American companies that cooperate with Huawei and Chinese companies that need to rely on cooperation with American companies to survive, have to stop cooperation with Huawei, resulting in Huawei in the chip industry can not continue to research, it is this neck incident and the previous countless suppression of mainland self-developed products from the United States, so that we wake up to the fact that we can not rely on others in science and technology products, we can only rely on ourselves, only if we have technology, can we not be suppressed, In order to grasp the right to speak internationally.
Western sanctions against us do not affect our enthusiasm for scientific research in the slightest, but we are very different from the United States in the operation of the space model
Commercial space operations in the United States
After the economic bubble burst in 2008, the United States began a serious financial crisis in the country, and had to temporarily stop throwing money to develop the space industry, so it decided to use the mainland public-private partnership to carry out the space industry, Musk's spaceX is the product of this era.
The use of this method has made the US space agency NASA and Musk's spaceX have a continuous contact, in which the two mutually beneficial and win-win, so that aerospace in the civilian field is also developing rapidly. Not only does it reduce the financial pressure on space development, but it can also decentralize some of the less important technologies for the profitability of private enterprises.
It cannot be denied that Musk's thinking is very correct, Lin Baojun, the chief designer of Beidou satellite, said that the transfer of part of the aerospace industry to private enterprises, to a certain extent, can improve the scientific and technological level of private enterprises, and can also allow the country to save a lot of money when investing in scientific research. In the case of successful development, private companies can also make huge profits with the commercial use of these less important technologies, making them more capitalized in the development of technologies. This is the space business model currently used in the United States.
Although we cannot yet adopt a public-private partnership model like the United States, we attach no less importance to the space industry than the United States.
The mainland attaches great importance to the aerospace industry
On the aerospace chip, the mainland's scientific researchers have achieved the qualitative change created by China like high-speed rail, and catching up with the West is not overnight, but the countless days and nights of mainland researchers, leaving countless sweat to do it, praising countless researchers who work silently behind their backs.
Now the mainland has classified the chip industry as the first of sixteen major projects of the Ministry of Science and Technology, and the mainland's attention to the chip field has also aroused the confidence of scientific researchers, rolling up their sleeves and working hard to achieve all the localization of these high-tech industries.
Looking back at the United States, in the early stage of the development of the mainland's space industry, the malicious suppression and sanctions all lost their effect, I am afraid that the intestines are repentant, facts have proved that deliberate sanctions will only stir up our blood, so as to catch up, we Chinese in our bones are not willing to admit defeat, and we are never willing to fall behind others.
Penpal commentary
China Airlines does it itself, from scratch, from 0 to 1, spend more money, these money circulate in the country, driving the common progress of the industries involved, in this sense, it is not possible to measure drops with money!
And just recently, the mainland has also begun to promote the development of commercial products and military products, I believe that in the near future, our parts quotation will be lower and lower.
From ancient times to modern times, bright sunshine, endless milky ways, people have never stopped exploring space. From the mythical story "the moon is Chang'e's hometown" to the "ten thousand households" dedicated to science during the Qing Dynasty, they realized their yearning for the sky with simple devices. The ancestors of human beings have never stopped exploring and yearning for space, using meager strength, endless sweat, and thin wisdom to explore outer space.
