The largest missile center in China is falling out of control in orbit, after it carried part of the new space station into space last week. The object is expected to fall to Earth during an “uncontrolled re-entry” on May 8 or 9. Whether it falls harmlessly into the ocean or affects the land where humans live, the reason the Chinese space program allows this to happen is – again – unclear. And given China’s planned launch schedule, it is entirely possible that such uncontrolled re-imports continue to occur. Missile Truong Chinh 5B in a launch in 2020. (Photo: Xinhua) The China space program has a series of major spacecraft achievements over the past six months, including bringing back lunar rocks and sending spacecraft into orbit around Mars. However, the programs seem to continue to pose a small, though small danger to people across the planet without control of the path of the launched missile. Jonathan McDowell, an astrophysicist at the Center for Astrophysics in Cambridge, Massachusetts, who tracks objects in space, says: “I think it was their negligence. I think it is irresponsible. The uncontrolled drop is the reinforced core of Truong Chinh 5B, designed to lift large, heavy sections of the space station. For most rockets, the lower layers typically fall back to Earth shortly after launch. The upper layers, when they reach orbit, often reactivate the engine (after releasing the load), directing them to re-enter deserted areas such as the oceans. For the past three decades, only China has lifted layers of such large rockets into orbit and let them crash somewhere, said Dr. McDowell. “It is a technical decision based on possibilities.” He said that Chinese engineers were able to design the trajectory of the rocket so that it would remain in orbit, fall back to Earth shortly after launch, or they might have planned to activate the booster. fig to get it out of orbit in a non-dangerous way. Ted J. Muelhaupt, director of the Center for Orbital Research and Aerospace Debris re-entry, says: “The reintegration design cannot be taken lightly, it’s something the world as a whole has done because we need it.” As for Truong Chinh 5B reinforcement, it could be anywhere between 41.5 North latitude and 41.5 South latitude. That means Chicago, located further north, is safe, but big cities like New York could suffer. On May 6, Aerospace Corporation, a federally funded nonprofit that conducts research and analysis largely, predicts the re-entry will take place on May 8 at 11:43 p.m. Eastern time (10:43 p.m. 9/5 Vietnam time). If that is correct, the debris could fall to Northeast Africa, in Sudan. The timing uncertainty – a 16-hour fluctuation – and location are still large. A day ago, Aerospace predicted the re-entry site an hour in advance in the Eastern Indian Ocean. The calculations are complicated by many factors, for example, the sun. The increase in the intensity of the solar wind – charged particles sprayed by the sun – will inflate the Earth’s atmosphere, increasing its force on the object and increasing its rate of fall. The movement of the object also affects. The US Space Command and the Russian space agency are both monitoring the missile division. The Russian statement noted that the re-import will not “affect the territory of the Russian Federation” . The US agency meanwhile promised to update it regularly before the event was likely to take place. Currently the object is moving at a speed of about 29,868 km / h, so prediction of position also changes with each minute. China plans to launch several more launches in the coming months as the construction of its third space station is completed, known as the Heavenly Palace, or “palace in the sky”. That would require additional flights of giant rockets and the possibility of more uncontrolled re-imports leaving people on the ground anxious to follow, even when mishaps from single parts. very small. Jen Psaki, White House press secretary, said on May 5: “For the mutual benefit of all nations, it is necessary to act responsibly in space to ensure the safety, stability, security and long-term sustainability of space activities”. America hopes to push “Responsible spatial behavior”.

In fact, in our lives there are many “extraordinary profit” industries that are easily overlooked, and the cost is much lower than that of the health care industry. It is suitable for people who want to choose a light asset business, and they can get what they don’t want. To make a fortune, this “great profit” industry is the waste recycling industry. Used clothes recycling For many young people, disposing of waste clothes is a big problem. I feel that it takes up space when it is idle, but it is a pity to throw it away, and it is impossible to sell it on the Internet. In recent years, there has been a sudden upsurge of waste clothes recycling in various places, and there are many old clothes recycling bins downstairs in the community. In fact, my country exports a lot of used clothes overseas every year. According to statistics from the official website of waste textiles, about 26 million tons of waste textiles are exported overseas every year. After they are overseas, they are washed and disinfected by local distributors, and finally flowed in by hanging tags. In the market, the unit price can range from $1 to $10. One can imagine how high the profit is. And those old clothes that do not meet the export standards will be recycled and processed into industrial and agricultural materials. Many people also want to know whether we ordinary people can enter this industry? In fact, a long time ago, there were many small vendors who bought used clothes in rural areas, which cost about 0.1 yuan per catty. After sorting, resell the good clothes to used clothes wholesalers, and sell the different clothes to the renewable resource company, so that you can get higher profits. Waste paper recycling In addition to the recycling of used clothes, the waste paper recycling industry has also achieved wealth creation myths that people can never imagine. Zhang Yin, the founder of Nine Dragons Paper, started from waste paper recycling, and in 2009 she topped the Hurun Rich Women list. In April 2021, he was once again selected as the Hurun Global Rich List with 59 billion yuan in assets. Many people should be unbelievable. We usually disassemble the paper shells that we throw away from express parcels, and others have earned tens of billions of net worth! Recently, due to increasing papermaking costs and increasing paper demand, well-known domestic paper companies have issued notices to raise prices. Paper giants such as Vinda, Qingfeng, and Jierou all plan to adjust prices by more than 10%. In the future, the recycling and reuse of waste paper may become the focus of special attention. Recycling of used electronic products Nowadays, the replacement of electronic products such as mobile phones and computers is too fast. People are constantly pursuing the latest generation of electronic products, so that there are a lot of waste electronic products idle at home. According to data from the Ministry of Industry and Information Technology, the total stock of used mobile phones in my country in 2014 was about 1.83 billion units, and the number of mobile phones eliminated in 2019 reached 499 million units. With the advent of the 5G era, it is expected that the number of mobile phones out of my country will increase to 524 million units this year. Although old mobile phones are of little value, the heavy metals in waste electronic products can cause damage to the environment. Many people have also discovered the business opportunities in this. By recycling electronic products, refining the metal for recycling, it can be environmentally friendly and profitable. Why not? Even Jack Ma has invested in the second-hand mobile phone platform “Cuihuibao”, which shows the potential of this industry. According to expert predictions, second-hand mobile phones will reach a market size of 100 billion yuan. It is worth mentioning that the state has also “recognized” the waste electronic product industry. On March 23, 2021, according to the announcement of relevant departments, the “Waste Electrical and Electronic Products Treatment Fund Subsidy Standard” will be implemented from April 1 this year. It is stipulated that the subsidy standard for waste products such as televisions, washing machines, and microcomputers ranges from 25 yuan to 100 yuan per unit. The main reason is that electrical and electronic products such as televisions and microcomputers still have residual use value even if they are scrapped. For example, 90% of the old circuit boards can be recycled, which has a high recycling value. However, according to incomplete statistics, the number of circuit boards discarded every day in the world has reached several billion. Recycling through different processing methods will ultimately lead to different profits. However, here is a reminder that compared to used clothing recycling and waste paper recycling, the recycling of waste circuit boards requires qualifications, and private processing is not allowed. Therefore, if you want to enter this industry, the threshold is still relatively high. As the saying goes, “Three hundred and sixty lines, you will be the champion.” Those inconspicuous waste items around us are actually very “rich”! In addition, we shouldn’t take “tinted glasses” to treat people who do waste recycling, are you right?
