There is no such thing as stealing technology! China successfully launched an arrow and eight stars, and the United States has contributed to the "space blockade" for 11 years

In recent years, the rapid development of China's aerospace industry has been witnessed by all, and the missions of Chang'e-4, Chang'e-5, Zhurong Mars Rover, and China's space station have directly sent China into the ranks of space powers. The first country to land on the far side of the moon, the second country to successfully land the rover on Mars, the country that successfully retrieved the soil from the moon and let the United States also want to get some samples, the first country to build a space station on its own...

China successfully launched eight stars with one stone

At 10:38 a.m. on May 5, another exciting thing happened, at the Taiyuan Satellite Launch Center, China successfully launched an arrow and eight satellites, including the Jilin No. 1 wide-ranging 01C satellite, all of which were sent into the predetermined orbit by the Long March 2 Ding carrier rocket!

The 8 satellites were artificially designed in a "round table" layout, with the center of gravity of the main payload satellite being raised and the remaining 7 satellites scattered in various positions on the disk. Of course, the specific amount of elevation, as well as the disadvantages of the landing point position, is certainly not random, but has undergone a series of cumbersome processes such as three-dimensional design, human-computer simulation operation and digital proofreading.

To smear success is to steal technology? "Wolf Clause", don't forget!

It is necessary to briefly say that this Long March II Ding carrier rocket, which is actually developed on the basis of the first and second stages of the Long March 4 carrier rocket, has two main directions of launch missions, one is a sun-synchronous orbit satellite, the other is a geosynchronous orbit satellite, just successfully launched an arrow and eight stars, that is, 7 Jilin No. 1 high-resolution 03D satellites and Jilin No. 1 wide 01C satellites, which belong to optical remote sensing satellites.

However, you may not know that although the Long March 2 Ding carrier rocket was developed in 1990 and successfully launched for the first time in 2 years, in 2012, the rocket was awarded the title of gold medal rocket, and so far it is still the shortest rocket model with a test launch cycle of any liquid carrier rocket in active service on the mainland.

We often say that science knows no borders, but scientists have borders, and on April 15, 2011, the then President of the United States signed a seemingly inconspicuous "special" clause, which roughly meant that there could be no exchanges and scientific research activities related to space technology between the United States and China, including of course NASA, and no space program could cooperate with the mainland, even any institution with a continental background.

Moreover, after the signing of the Wolf Clause, they really did what they said, when the Endeavour was launched, there were also media reporters from the mainland who went to the mainland, originally to conduct interviews, but because of this extra clause out of thin air, they were then rejected, and at the beginning the interview pass promised by NASA was not given to our reporters.

Of course, one could argue that the United States didn't do much to help us with space technology until there was the Wolf Clause. Indeed, the current situation of China's space industry is not easy to come by, and it is the result of the joint efforts of several generations of scientists, especially those who gave up foreign preferential treatment and even returned to China. But the signing of such a clause, let alone to give technical help, even normal communication has been blocked, if there is any benefit, it is difficult to be smeared with the label of stealing technology!

In recent years, China's aerospace industry has developed rapidly, and the "space blockade" behavior of the United States for 11 years has actually made a contribution?

As we all know, the Chinese space station is expected to be completed in orbit in 2022, the key technology of the space station at this stage has also been verified, and soon after, that is, in 2023, China's first large-scale space survey telescope will be launched, you can simply refer to it as "sky survey"!

The Chinese sky survey telescope that will be launched is about 3 stories high when erected, although the caliber is similar to the current Hubble Space Telescope in the United States, all at 2 meters, but its field of view (that is, the cosmic field of view that the telescope can see) is larger, 350 times larger than the United States Hubble telescope!

Moreover, the main focal surface of the Chinese sky survey telescope module is actually put together by 30 detectors, so even if each piece is separately, it will be larger than Hubble's detector, and the number of pixels will be more, and when the successful launch and operation begins, the sky survey will become the largest "camera" in the space world, and expand the wide-area sky survey observation, and then there is a hope to get a large number of research results that everyone pays great attention to, such as with dark energy, A major innovation in the close connection between dark matter and the various celestial bodies in the solar system.

China's space industry began in 1956, which was relatively late with the United States and the former Soviet Union, and it was difficult to start, until 1970, when we finally launched our first artificial earth satellite, but China still became the fifth country in the world to independently launch artificial satellites by its own efforts.

China only launched its first satellite half a century ago, but in just a few short decades, China's ambitious space program is compelling enough, especially when our rover successfully landed on Mars! If you want to say what the key to China's space progress is, it must be self-reliance and self-improvement!

Even though the United States uses terms to restrict the contact between Chinese scientists and NASA, our steps to explore space have not slowed down, and it can even be said that the "space blockade" behavior of the United States in the past 11 years has even accelerated the development of the mainland's space industry. For example, the Tiangong space station currently under construction on the mainland is likely to become the only space station in orbit in a few years, and more than a dozen countries have successfully applied to join the mainland space station for scientific research, although the United States has been rejected because it does not meet the requirements, but Japan, Russia and India have all passed the application.
