"The Chinese spy satellite was destroyed by Russian space debris?"

The hype of foreign media sharing the QR code with wechat scanning code to friends and circle of friends can be described as "demons dancing" "this is the second confirmed major space collision accident." Australian "sky" news website said on the 20th that Dr. Brad Tucker, an astrophysicist and cosmologist at the Australian National University, said that it had been confirmed that a Chinese satellite collided with a Soviet era rocket fragment in space in March this year, "and the accident was also confirmed by the US space force" er... Why doesn't China know about the major space accidents that have become so popular in the west the whole thing has to start on August 18. On the same day, the US "space" website published an analysis article by Jonathan McDowell, an expert from the Harvard Smithsonian Center for Astrophysics. According to the tracking data of the US space force, the yunhai-1 02 satellite launched by China in 2019 may collide with the rocket debris launched by the Soviet Union in 1996 on March 18, 2021 this is not the first time that yunhai-1 02 satellite has reported a space collision. As early as March this year, the 18th surveillance squadron of the US space force announced that on March 10, the retired NOAA-17 meteorological satellite exploded and disintegrated in space and broke down into 16 detectable fragments; Then it was announced that China's yunhai-1 02 satellite also exploded and disintegrated in orbit on March 18, turning into 21 detectable fragments. At that time, the outside world speculated whether there was a connection between the explosion and disintegration of the two satellites one after another, but the official statement of the US space force was that "no space collision was found, which may be the explosion of the propulsion system of Chinese satellites" China did not respond to this at that time. In April, foreign astronomical observers found that yunhai-1 02 was still sending radio signals to the ground regularly, so the argument that it had exploded and disintegrated was once dismissed McDowell brought up the old story again because he noticed that the Soviet "zenit-2" rocket wreckage numbered 48078 added the description of "collision with satellite" in the recently updated earth orbit wreckage catalogue of the US space force. Tracking records show that the rocket wreckage with a size of about 10-50cm passed yunhai-1 02 on March 18, only 1km away. "Considering that Yunhai satellite and rocket debris fly faster than bullets, there is a great possibility of collision within the observation error range of 1 km," McDowell said He stressed that so far, the collision accident has produced 37 observable space debris, and other debris may not be tracked the report stressed, "this will become the largest collision accident in space in 12 years." The previous largest space collision accident occurred in February 2009, when the Russian military satellite "cosmos-2251" collided with the American "iridium-33" communication satellite over Siberia, resulting in 1800 pieces of debris McDowell explained why yunhai-1 02 was still transmitting radio signals. It was obvious that it survived the violent impact“ Radio enthusiasts can still receive signals from the satellite, but it is unclear whether the Chinese satellite can still complete its design mission " although the report on the US "space" website was full of speculation and did not produce reliable evidence of space collision accidents, some foreign media soon began to "rhythm" with bad intentions. For example, many foreign media have referred to yunhai-1-02 as China's "military satellite" or "spy satellite", and believe that China did not respond positively to the "serious space collision accident" because the satellite was carrying a sensitive mission for example, the "India today" website said on the 20th, "the mysterious impact in space damaged the Chinese spy satellite. Is this a man-made collision or explosion?" The report also linked the matter with China's anti satellite test in 2007 and the re-entry of the wreckage of the long march 5B rocket into the atmosphere in May this year, suggesting that "China is irresponsible in space" on the 20th, the US "Forbes" website deliberately provoked Sino Russian Relations: "if it is confirmed that the space collision accident was caused by Russian debris, can China Sue Russia for damaging its spacecraft?" the foreign media hyped the news that "the Chinese satellite was hit by Russian space debris", but when the old driver asked many people in the industry about "whether there was a space collision accident on yunhai-1 02 satellite", the reply was "I haven't heard" at present, China's aerospace industry has not given an official response on "whether there is a space collision between yunhai-1 and 02". However, the old driver believed that if such a "significant" space collision accident really happened, China could not hide it and there was no need to hide it the old driver thinks that the most reasonable reason why China did not respond is that yunhai-1-02 satellite is running well now. Why do we have to respond to the strange question of whether there was a collision? According to official information, yunhai-1-02 satellite is a satellite developed by Shanghai Institute of aerospace technology affiliated to China Aerospace Science and Technology Corporation. It was successfully launched by long march-2-d rocket at Jiuquan Satellite Launch Center at 8:54 on September 25, 2019. It is mainly used for atmospheric and marine environment element detection, space environment detection Disaster prevention and mitigation and scientific experiments. All the information of the satellite is very transparent. Some foreign media have to forcibly link it with military satellites and spy satellites, and its intention is self-evident western media have been trying to discredit China's aerospace in recent years, but the old driver wants to say that most of the space debris in earth orbit are made by the United States. Who is irresponsible? Moreover, European and American enterprises are vigorously sending Internet satellite constellations composed of thousands or even tens of thousands of small satellites to low earth orbit. The "space" website also warned that these unprecedented numbers of satellites have sharply increased the probability of collision accidents in low earth orbit for some countries that want to "show their responsibility for space", take care of your own family first
