罕見航天事件！中共火箭對標SpaceX獵鷹9 結果悲劇了！

On the 30th, the mainland social media posted several videos of the Henan Gongyi Rockets falling and exploding. On the evening of the same day, Beijing-based Tianbing Aerospace Technology Co., Ltd. published a statement on the launch of the Tianlong-3 large-scale liquid-carrying rocket Yizi-class power system. During the launch of the Tianlong-3, the Yizi-class rocket normally ignited. However, due to a malfunction in the connection between the launch site and the test site, the Yizi-class rocket fell off the launch site. After taking off, the rocket fell to a deep mountain 1.5 kilometers southwest of the test site. After the rocket fell into the mountain, it disintegrated. After a thorough investigation, no casualties were reported. However, a villager in Xuzhuang Village, Dayugou Town, Gongyi City, reported that the rocket's launch site was only one mile away from his home. After the Tianlong-3 rocket accidentally escaped from the launch site, it fell and exploded, causing netizens' attention and enthusiasm. The national defense immediately came out to maintain stability, claiming that no casualties were reported. However, the netizen's message area shows that many people have questioned. It's so close to the residential area. There are still people in Henan who are so ugly that there are still places to fly rockets. This thing is scarier than the gas station. The gas station knows that it cannot be set up in the residential area. It is necessary to plan this route away from the town. Now it feels like playing with fire. Weibo user Bola's surprise post said, Tianbing Technology is really too low-level this time. Explosive rockets are developed. In essence, it is the price of a controllable close launch. Let the problem be fully exposed. What is the core? Lao Ma's rocket is a specially designed launch pad. There are no people around. And there is a rough estimate of the severity of the first explosion of the rocket. The safety measures are also good. The incident of Tiangong No. 3 in Henan Apartment is when the ground-level nine engine dynamic test vehicle did not catch the rocket with the ground-fixed device. In a situation where there is no preparation at all to break through the final safety measures, it went up in a hurry. Then it went out of control quickly and exploded in the mountains. The article pointed out that there was no preparation in advance. Gongyi is just a ground-level test vehicle site, not a launch site, and does not have launch conditions. The final safety measures failed. It exploded directly in the sky. The staff, the citizens of Gongyi, and the people are stupid. It is a very low-level and stupid mistake. We can only pray for no casualties. The mainland self-media Global Science Cat pointed out, Tianlong No. 3 rocket fell in Gongyi, Henan. This is indeed a bit incredible. The structural failure of the ground-level test platform connection actually caused such a problem. This is probably a very rare space incident. This rocket, in terms of performance, is completely in line with SpaceX's Falcon 9. Its diameter is 3.8 meters. Take-off mass is 590 tons. Ground orbit is 17 tons. Solar orbit is 14 tons. All the data looks good. But after the fire, there was a problem. The Beijing authorities have always claimed that they are in the lead in all areas. Even if they fall behind, they will catch up immediately. But in recent years, Chinese people have repeatedly photographed rockets falling out of the sky. On June 24, less than 10 days ago, X account Mr. Li, not Mr. Ni, posted a statement. Residents of Guizhou, Qiannan, and Buyi, Miao Autonomous Prefecture, recently photographed a rocket crash. It is worth noting that when people are photographing a spacecraft crash, some people remind them not to upload the video to TikTok. Others also specifically remind that they may not want to make a fool of themselves, or they may be worried that after the people shoot the video, they will be troubled by the local police. X account Beryl1 posted a video on June 23, saying that the Long March-2 carrier rocket took off from the Sichuan Xishang Satellite Launch Center and fell into a village. It is likely to be located in Guizhou Guiding County. The video shows a huge unidentified object hanging in the sky with a yellow smoke and accompanied by a huge sound. Finally, the hill behind the village is not far from the residents. Some people ran away in panic. Netizen Nan Guigui shared the video on Weibo. Netizens went out to play and suddenly saw an object fall from the sky. When it fell to the ground, it was still smoking yellow smoke. A netizen who has research on rocket launch posted a post on the Satellite Research and Production Union. According to the NOTAM flight mission notice before the rocket launch, the first-class drop zone of the Long March-2 is near Guiding County, the former southeastern province of Guizhou Province. In addition to the inland launch site outside the Nine Springs, especially in Xichang, there are often rocket disasters that fall near the densely populated areas. Most of the rockets in Xichang are long-range rockets like the Long March-3, which is very bad. But in the meantime, at least three have been irreplaceable. If you want to solve it, you can only wait for the future recovery of rocket development. Netizen Yun Xinxin asked, isn't it very accurate to predict and control the drop zone now? It is rare to see such a panic situation. The Satellite Research and Production Union replied, when the NOTAM was released, the rocket drop zone was given a quadrilateral area. Four points correspond to four coordinates. As for where the rocket drop point will be in this area, it depends on luck. This time, the luck is actually good. At least it didn't hit the house directly. Xinhuawang posted a message on June 22, saying that the Long March-2 carrying the Chinese-made Tianwen satellite was carrying the rocket. It took off in the air at the Xichang Satellite Launch Center that day. But there is no follow-up report on the drop of the rocket wreckage. At about 3 p.m. on the same day, the Xichang Satellite Launch Center in Sichuan carried the rocket to carry out the satellite launch mission. The rocket's flight path passed through the southwest of Taiwan towards the west Pacific. Most track-level rockets are designed to be safely pushed into the ocean or safely landed on the ground before being reused. But the Chinese-made Long March rockets usually return to the atmosphere uncontrollably. Every time the rocket hits the earth, it will cause people to worry because the rocket fragments may fall into the air in the residential area. As early as 2020, China's Long March-5B fragment had fallen off the coast of Xi'an in the West African country and damaged several local buildings. In comparison, European rocket design is very safe. Austrian Space Agency senior engineer Ludger Abbart, said in an interview with German TV that our European rockets will not let the first level of the rocket enter the orbit at the beginning of the design. The first level of the heavy rocket will not fly into orbit around the earth, but will fly along a runway after separation. In this case, its trajectory can be calculated in advance so that we can plan well before launch and make it land in the designated area in the Pacific Ocean so that we can plan the entry zone in advance to avoid risk to the ship and crew. The key point here is not to fly too high and too far in the first level of the rocket to be able to calculate the trajectory in advance. Abbart said that unlike the first half of the Long March-5B, the Ariane 5 series rockets have a second level. This means that after the first level of fuel-consuming rockets, the first level of the rocket that will eventually enter orbit with effective cargo such as spacecraft is much smaller and lighter. Even if there is a malfunction it is uncontrollable. Compared with the second-level rocket debris, the first-level debris, which is heavy and large, is more likely to be destroyed and the risk to the surface is much smaller. The Beijing authorities have always emphasized that the last level of the rocket will be destroyed when it enters the atmosphere. This is an international practice. However, due to the unique first-level layout of the Long March-5B, its last level is the first level and it will be lighter than other rockets. When it enters the atmosphere, it can almost completely destroy the last level and is not at the same weight level at all. Astronomer Michael Dahl once said that in the past 30 years, only China has sent such a large rocket into orbit and then let it fall at will. Although the rocket debris has fallen and the risk to mankind is small, space observers are not satisfied with the situation of the team controlling the fall. Experts say this effect will be similar to a small-scale plane crash. It may not be as fatal as missile attacks and accidents but this risk can be reduced. The United States and the European Union have risk assessments. If there is more than a ten-thousandth chance of injury, it will not launch. But China's standards seem to be much lower. After the second launch of the Long March-5B rocket in 2021, it experienced a state of uncontrollable flight for more than a week, causing concern in all sectors. The jet debris finally fell into the Indian Ocean near Maldives. At that time, US Secretary of State Bill Nelson said it is clear that the Chinese Communist Party has not reached a responsible standard Countries engaged in space activities must reduce the risk of space objects returning to Earth to mankind and property and keep these actions transparent Whether the rocket debris will eventually cause harm to mankind is not clear. Why did China's space plan make this situation happen again and again? Considering the CCP's launch plan, there may be more rocket outages in the next few years. Due to the inability to control the rocket launch path, this will continue to worry people all over the country. Okay, that's all for today.
