China Space Station Tianhe Core Module Launched Successfully

At 11:23:15, 618 milliseconds on April 29, 2021, the China Space Station Tianhe Core Module was lifted by the Long March 5B carrier rocket and successfully launched into orbit to the scheduled orbit, unveiling the construction of the China Space Station. With the successful separation of the Tianhe core module from the rocket and entering the predetermined orbit, the two wings of the solar windsurfing board were deployed smoothly and working normally. The launch mission was a complete success, marking the full launch of the orbital assembly and construction of the Chinese Space Station.

Xi Jinping calls congratulations on the successful launch of the Tianhe core module of the Chinese space station-Xinhuanet

According to media reports, the space station Tianhe core module will be launched on April 29. The launch mission will be carried out at the Hainan Wenchang launch site. The core module will be lifted off by the Long March 5B Yao-2 carrier. At present, the launch of the core module has entered the countdown stage, which also means that the prelude to the construction of my country’s space station is about to begin. This will be another milestone in China’s manned spaceflight.

It’s done! In a word: The normalization of manned spaceflight has just begun. The “Long March 5 B Yao 2” carrier rocket has experienced more than 8 minutes of flight and successfully lifted the sky and the core module into the scheduled orbit. The curtain for the construction of my country’s space station is on. Pulled away slowly. Time flies and time flies. Today’s “Long March V” series of carrier rockets have successfully flew five times in a row, and they are very likely to become the next “golden rocket”. Xinhua News Agency watched the flight, and the author even yawned. This is a completely different mentality compared with the breathless stare when the “Long March 5th and 3rd” went around more than a year ago. When we think that the success of the “Long March 5” carrier rocket is not a new thing, it shows that our realm has taken a new level. The five-star red flag lights up the starry sky. The Chinese space station officially started to return to the mission itself. The payload of the mission’s “Tianhe” core cabin weighs 22.5 tons, setting a new record for the maximum mass load of 21.6 tons set by the new manned spacecraft last year. Its volume has reached 50 cubic meters, which is also my country’s current record. The largest payload launched is still my country’s most versatile spacecraft so far. The successful launch of the core module of the “Tianhe” opened the prelude to the construction of my country’s “Tiangong” space station. From an overall point of view, the “Tianhe” core cabin can be divided into three parts-node cabin, small column section and large column section. Authorized from Xingzhi Technology, each component is marked by the author, the node cabin and small column section The diameter is 2.8 meters, and the diameter of the large column section is 4.2 meters. This design has sufficient scientific basis-since the diameter of the Long March No. 5 is 5 meters, the diameter of the bottom end of the fairing is also 5 meters, while leaving a part of the safe space. Therefore, the maximum diameter of the internal load is 4.2 meters. Not only the maximum diameter of the core compartment is this number, but the diameter of the new manned spacecraft test ship launched in May 2020 is also 4.2 meters. Furthermore, we can partition the space station’s functions, including the node capsule for expanding the scale and also for space walks; the living and resting area (located in the small column) for the members of the capsule, the work, scientific research and The control compartment of the control compartment (located at the front end of the large column section and the rear end of the small column section), and the resource compartment loaded with important resources such as fuel (located at the rear end of the large column section). Is it “plagiarism” if it looks like a “mir”? Don’t misunderstand “Tianhe”. At this time, you may have noticed that this core module looks like the core module of the Mir space station in terms of appearance and function. However, this neither shows that we are behind the Russian Aerospace for decades, nor is it a “plagiarism” of the Russian plan, but by design. Imagine that if the core cabin is completely designed as a 4.2-meter-diameter column, then there will be no place to install external facilities such as solar panels, robotic arms, and communication antennas, and because the top of the fairing of the Long March 5 is converged into Approximately tapered, so obviously there will be some waste of space at the top. Therefore, the installation of a small column section and node compartment with a diameter of 2.8 meters will help the installation of external facilities and the utilization of the fairing space, and expand the overall volume. Good designs are mostly similar, and they follow similar scientific and technical principles behind them. Moreover, although the appearance is similar, the “Tianhe” core module is quite different from the “Mir” core module. The “Tianhe” core cabin comes with a dedicated airlock for exit activities, while the “Mir” does not have such a design. All of them are docking interfaces, which means that the “Mir” can only be used for exit activities during the initial stage of station construction. It is very inconvenient to realize through the 800mm diameter counter interface. Not only is it more convenient for astronauts to get out of the cabin, the robotic arm of “Tianhe” located on the large column can further expand the astronaut’s range of activities outside the cabin. It will also become very convenient for both extravehicular experiments and on-orbit maintenance. Although with the construction of the space station, the main airlock will be taken by the “Wentian” experimental cabin, the exit hatch of the node cabin can still be used as a backup exit hatch. The main energy of “Tianhe” comes from two solar wings-unlike the hard solar panels of the Mir, this solar wing is made of flexible material. Without changing the output power, the flexible solar wing achieves a large The weight is reduced, and the envelope size when folded is also smaller. “Tianhe”‘s own power system can maintain orbit by itself, and can be supplemented with propellant on orbit by the “Tianzhou” series cargo spacecraft. The on-orbit propellant injection technology successfully tested by “Tianzhou-1” will finally be applied today, a few years later. At the same time, installing a series of momentum wheel modules between the small column section and the large column section will enable the space station to slowly change its posture during operation and reduce fuel consumption. Moreover, the “Tianhe” core cabin also has its own ion engine. This extremely high specific impulse engine will further save valuable fuel. These measures can allow the core cabin to run longer in orbit. “Tianhe” modular and standardized in-cabin scientific experiment cabinets and standard experiment units installed in the scientific experiment cabinets will make space experiments more convenient-as long as they follow the same technical standard, they will all be able to be incorporated into science The experiment cabinet not only facilitates the operation of the astronauts, but also improves the use and turnover efficiency of the scientific experiment cabinet. At the same time, during the operation of the experimental cabinet, a large amount of experimental data will be continuously descended to the ground through the high-gain antenna that comes with the core cabin, so that researchers on the ground can grasp the working status of the scientific research load in the space station in real time. I believe that through a series of scientific experiments, we will gain a new understanding of the space environment. “Tianzhou” and “Shenzhou” are ready to go. The excitement will continue to let us turn our attention to the follow-up tasks this year. The “Long March 7” and “Tianzhou 2” are still being assembled intensively. Next month, the “Tianzhou-2” cargo spacecraft will be fully loaded with supplies to dock with the “Tianhe” core module, waiting for the arrival of the astronauts on the scheduled orbit. The crew of “Shenzhou 12” is also training for the “Tianhe” on-orbit mission, and the astronaut crew is ready to come out. More than four years have passed since the last time a Chinese astronaut entered space. The last time, astronauts Jing Haipeng and Chen Dong lived in space for 33 days, completed a series of space science experiments and technical tests, and achieved the goal of astronauts’ mid-term residency. After the completion of the rendezvous and docking of Tiangong-2 and Shenzhou-11, the astronauts opened the door of Tiangong-2 and successfully entered the “Tiangong-2” space laboratory (picture source: see watermark) This year, the Chinese will return to space, for The peaceful use of space by mankind has made new and greater contributions. Not only that, we will also enter a new era of normalization of manned spaceflight. Because this year there will be a second group of astronauts set off. They will replace the first crew and continue to perform on-orbit missions in space. If everything goes well, we will get more first-hand information about the long-term impact of the space environment on astronauts, and this information is very precious, even for the United States, Russia and other major space powers, the content disclosed in various journals is also Just the tip of the iceberg. Still this year, “Tianzhou 3” will also set off for the “Tianhe” core module to replace “Tianzhou 2”, provide more supplies, carry out more experiments on key technologies for space station operation, and ensure that the core module is in orbit. Operation to meet the survival needs of the astronauts in the core module. The task will continue. Beginning next year, the “Tiangong” space station will be further expanded: the two experimental modules “Wentian” and “Mengtian” will be launched by the “Long March 5B” carrier rocket. They will be docked with the core module respectively, in the two experimental modules. After the docking is completed, the construction period of the “Tiangong” space station will end. Schematic diagram of the Tiangong space station (China National Space Administration) By then, the greatly expanded scientific experiment cabinet will turn the “Tiangong” space station into a national “space laboratory.” At that time, in addition to astronauts who were born as pilots, scientific researchers will also enter space and become “load experts” to conduct research in orbit more efficiently. After these constructions, we will see a completely predictable future-the barriers to entry into space will inevitably be lowered. After reading this article, you may also have the opportunity to travel the Xinghai in the future. A few years later, the “Sky Survey” space telescope will also set off to space, flying in common orbit with the space station. The space telescope will focus its gaze on the deep and vast universe, bringing us more magnificent wonders of the universe. Here we want to particularly emphasize the concept of “common-orbit flight”. Since the telescope and the space station are flying in a common-orbit, it will greatly reduce the difficulty and cost of maintenance of the telescope. Astronauts in the space station can be ready to provide maintenance services for the space telescope at any time, so that it can work longer and more stable. Our footsteps will still not stop. In the longer term, the scale of the “Tiangong” space station may even be further expanded-if we send the second core module, the third and fourth experimental modules into space and dock with the “Tiangong”, then we will Get a large space complex weighing 180 tons! Perhaps by that time, visitors of different languages ​​will be welcome in the space station. On the ground, the barriers between people exist in the form of national boundaries, while in space, we will be like brothers and sisters, and work together to explore the unknown borders and peaceful use of space for the species of mankind. The footsteps to the Xinghai never stop. Just as you read this article, the “Tianhe” core module has entered a predetermined orbit. Starting today, China’s manned spaceflight industry has been transformed. The length of Chinese astronauts’ lives in space will continue to grow after four years of stagnation, and will continue to grow. We have missed the sea, but this time, we will never miss the Xinghai.

The five-star red flag is shining in the dazzling galaxy, a new starting point for mankind to explore space!
At 11:23:15, 618 milliseconds on April 29, 2021, the China Space Station “Tianhe” core module was lifted by the Long March 5B carrier rocket and successfully launched into orbit to the scheduled orbit, opening the curtain of the construction of the Chinese space station. .
Tianhe, turn on! It is said that “Tianhe” is named after Tianshu and Taihe, which means harmony between heaven, earth and people; and some say that the word “Tianhe” comes from “Zhuangzi·Knowing the North Tour”: “If you are in the shape of your body, you will see it, and Tianhe Coming soon.” The general idea is: correct your body, concentrate your attention, and the harmony of heaven and earth will naturally come. Either way, the romantic and grand naming of China Aerospace always complements each other and is inseparable from China’s rich and brilliant history and culture. In the early stage of the project, through the implementation of four unmanned flying missions and the manned missions of Shenzhou 5 and Shenzhou 6, the first mission goal of the project was achieved. Through the implementation of the Shenzhou 7 flight mission, as well as the Tiangong 1 and Shenzhou 8 and Shenzhou missions The rendezvous and docking tasks of the 9th and Shenzhou 10 have completed the first phase of the second step of the project. From June 2016 to April 2017, through the implementation of the first flight of Long March 7, Tiangong-2, Shenzhou-11 and Tianzhou-1, a total of four missions, the second phase of the second phase of the project was fully completed. The main tasks of the space station stage are around 2022, to build and operate my country’s manned space station, master long-term manned flight technology in near-Earth space, and have the ability to carry out long-term near-Earth space manned scientific experiments, technical experiments, and comprehensive development and utilization of space resources. The construction of the space station is divided into two phases: key technology verification and construction. Among them, the key technology verification phase of the space station plans to implement 6 missions. The first flight mission of the Long March 5B carrier rocket was successfully completed in May 2020. In 2021, it is planned to launch the space and core cabin, 2 cargo spacecraft and 2 cargo ships. People spaceship. In 2022, we will implement 6 missions during the construction phase of the space station, launch Wentian and Mengtian experimental cabins, 2 cargo spacecraft and 2 manned spacecraft, and complete the orbital assembly and construction of the space station. In other words, in accordance with the established mission plan, my country will complete the on-orbit construction of the China Space Station through 11 missions this year and next, including 1 core cabin and 2 experimental cabins, 4 cargo spacecraft and 4 cargo ships. The manned spacecraft will build a large-scale low-orbit permanent space station with flexible tonnage (60-180 tons) to achieve the mission goal of the third step of the three-step development strategy of China’s manned space project. Why do humans want to build a space station? What space stations have been built in human history? What is the development history of China’s space station? What is the “three-step” development strategy of China’s manned space project… This article sorts out the public information and sorts it out. 1. The space station-the first stop for mankind to interstellar: a brief history of the development of the human space station

It’s a success! This is equivalent to a house, the foundation and the ground beam are all made! It’s plus or minus zero! Regardless of whether the follow-up task is successful or not, it will be easier to handle if the foundation has been established. If it is a big deal, come again. What are you afraid of where the foundation is? To be honest, what worries me most is the “Tianhe” core cabin. If this is not the case, it will be a big trouble. This is done. The follow-up task is sub-system engineering. Even if it fails, there are remedial measures. The most significant significance lies in this: when the house is at plus or minus zero, the rest of the work can be done slowly. Currently there are only two space stations in the sky: the International Space Station and the Chinese Temple. The ISS is old and broken, and Russia has also decided not to participate in the follow-up missions of the International Space Station, and will no longer provide support for the International Space Station’s life extension program. After 2024, Tiangong is likely to become the only space station in the sky. This is highly consistent with what is happening on the ground: China will become the only country on earth that still has a dream. Space stations, deep space exploration, and low-Earth orbit utilization are the three hottest areas of aerospace technology. At present, the only countries that can maintain activities in these three areas are China and the United States. While the United States is going downhill, China is going uphill. The downhill is arrogant, and the uphill is immersed in hard work, but it does not change the outcome. The US moon landing plan is still on the PPT. I personally think that the things of the horse gods are mainly for the stock market value. Of course, if you don’t agree, then you are right, you are all right. The current US space program is mainly focused on the use of low-Earth orbit and basic scientific research. There are more uses for telescopes, earth observations, military applications, communications and meteorology, etc. It can be said that there are no dreams… those things of the Martian people. Well, depending on how you look at it, I don’t think it’s called a dream, it’s called a dream stocks, Bitcoin, Dogecoin, Tesla. China is steadfastly step by step. The sky is in harmony with the sky, and the Mars rover is steadily fighting. The dream not only goes to the sky, but also shines into the reality. Let me say something boldly here: If you look at it after ten years, it is still true that China’s dream is true. Without dreams, what is the difference between humans and salted fish? Salted fish don’t need to eat, humans want to eat. China Aerospace carries the dream of the Chinese people, the highest and farthest dream, and this dream is the hope of mankind. The taste of salted fish in the world’s aerospace industry right now is completely different from that of the Cold War period. During the Cold War, space exploration was the vigor of young people, but now it has an old and sour smell. Technological progress has been a long, long time without any progress…Even the International Space Station is very old. China Aerospace, a new space station, a new moon landing project, a new deep space exploration project, a new space program and launch vehicles, this is the hope and future of mankind. There are also people on earth looking up at the stars.

The United States does not allow China to participate in the International Space Station, and even issued a law that does not allow interaction with the Chinese government in its space program. It’s okay, let’s make it ourselves! ! Napoleon once said: “China is a sleeping giant, let him fall asleep, because when he wakes up, he will shake the world.” Napoleon is a smart man, he knows the potential of China. After the end of World War II, the United States prohibited Chinese scientists from participating in nuclear bomb development. Chinese scientists started China’s nuclear program and developed China’s first atomic bomb. The rest is history. As the saying goes: The sleeping dragon has begun to wake up. The United States’ prohibition of China from participating in the International Space Station has nothing to do with the belief that China is not worthy of trust. It is America’s fear that China surpasses them in space technology. Therefore, just like the nuclear program, China has to act alone. Of course, history will prove that in these two incidents, China has overcome difficulties and achieved success. Western governments, especially the United States, will serve the world better if they study history and find ways to cooperate with China. The world today will be much better than it is now. but. They believe that they can stop China’s rise through destruction, so that they can maintain their hegemony and control over the rest of the world. China has been proving that this strategy will not work. They certainly did not consider what is good for the world, they only consider things that are good for them in the short term. China considers long-term things that are beneficial to the entire world. This is why China built its own space station. We can prove that their suspicion of us before was a joke. And if this is not a suspicion, but an excuse to contain us, then April 29, 2021 will be our mockery of them.

There is so much meaning. The space station serves as an experimental platform that can stay in a gravity-free, microgravity environment for a long time. Able to carry out many experiments that cannot be carried out on the ground. Including some biology and material science experiments, all can be carried out inside the space station. The establishment of a long-term space station not only has an important impact on China’s aerospace, but also has a significant impact on my country’s overall scientific research. It can bring inestimable gains to my country’s scientific research and the progress of scientific and technological research. In other words, in the space station, more scientific research can be carried out, and these scientific researches that can only be carried out in space will inevitably lead to technological progress, and technological progress will inevitably lead to an increase in productivity. Therefore, purely technically speaking, the establishment of the space station is far more important than other space achievements. It can even be said that the establishment of the Tiangong space station will bring leapfrog development to my country’s scientific and technological progress. Therefore, it is an exaggeration: the golden age of China’s aerospace has come, and the good times have come! Oh, one more sentence: This will also be the second golden age of human spaceflight!

April 19 this year is the 50th anniversary of the launch of the world’s first space station “Salute One”. Ten days later, the core module of the Chinese space station Tiangong was also launched. So far, mankind has developed three types of manned spacecraft: spacecraft, space shuttles, and space stations. Due to their short operating time and small volume, spacecraft and space shuttles are mainly used for transportation between space and earth, transporting astronauts and cargo to the space station. Space stations have the advantages of long life, large volume, strong functions, and many people. Ideal base for space resources. The research and development of the China Space Station is handled by the Fifth Academy of China Aerospace Science and Technology Corporation. According to Wang Xiang, the commander-in-chief of the space station mission of the Fifth Academy of China Aerospace, as the largest spacecraft in human history, the space station is a long-term operation in low-Earth orbit, which can meet the needs of astronauts living and working in orbit for a long time, as well as the search The human spacecraft represents the most comprehensive, most complex, most advanced, and most comprehensive scientific and technological achievements in the aerospace field today. “The focus of China’s spaceflight this year is the space station, and basically a lot of money is spent on it.” Zheng Yongchun, a planetary scientist at the National Astronomical Observatory, told China News Weekly. This year and next year, China will continue to implement 11 manned space missions, including 3 space station sections, 4 cargo spacecraft and 4 manned spacecraft launches, and complete the space station orbit construction in 2022. The “Tianhe” core module of the Space House can support 3 astronauts to stay in orbit for a long time, and the space for astronauts to work and live is about 50 cubic meters. It supports the development of scientific experiments and technical tests in and outside the cabin. It is the largest research and development in China. Spacecraft. According to the relevant designer of the Fifth Aerospace Academy, the core module is very large, with a length higher than a five-story building, a diameter much wider than a train and subway carriage, and a volume larger than any cabin of the International Space Station. The core module is the command and control center of the space station. Capable of rendezvous and docking, transposition and berthing, long-term crew stay, astronauts out of the cabin, and guarantee space science experiments; the sealed cabin is equipped with working areas, sleeping areas, sanitary areas, dining areas, medical supervision and medical insurance areas, and exercises It can provide comfortable and good guarantee conditions for the work and life of astronauts. It is equipped with microwave ovens, refrigerators, water dispensers, folding tables and other home appliances, space treadmills, space bicycles, resistance pullers and other fitness equipment to meet the daily exercise of the astronauts. The scene lighting in the cabin can be controlled by the mobile phone APP. In addition, the core module is also equipped with world-to-earth video call equipment, which can realize two-way video calls with the ground; there is also a measurement and control communication network and related equipment that can support astronauts to send and receive e-mails. According to Wang Xiang, the commander-in-chief of the space station mission of the Fifth Academy of China Aerospace, the previous record of Chinese astronauts’ flight time in orbit was 33 days. The necessary water and oxygen were sent directly into space by the spacecraft. In order for the astronauts to stay longer, this time the space station designed a renewable system: the water vapor exhaled by the astronauts will be recovered through condensed water, and the excreted urine will also be recovered and purified, and reused as drinking water and domestic water; electrolysis; The hydrogen produced during oxygen production and the carbon dioxide exhaled by the astronauts will produce oxygen through a chemical reaction. After the core module is successfully launched, the next mission will be the “Tianzhou II” cargo spacecraft, and then the manned spacecraft will be launched. After the “Tianzhou II” and the core module are docked, they will carry three astronauts. “Shenzhou XII” spacecraft will also enter the launch preparation phase. Among them, the cabins of the space station will be launched by the Long March 5B carrier rocket at China’s Wenchang Space Launch Site, the cargo spacecraft will be launched by the Long March 7 carrier rocket, and the Shenzhou manned spacecraft will be launched by the Long March 2F rocket at the China Jiuquan Satellite Launch Center. According to the plan, the Chinese space station will be built around 2022. It will operate in a low-Earth orbit with an altitude of 340 to 450 kilometers, and it will fly in orbit for more than 10 years. The space station is an outpost for mankind to fly into deep space, a large-scale scientific experiment platform for mankind in space. China Tiangong Space Station consists of three parts, including the “Tianhe” core cabin, and the two experimental cabins “Wentian” and “Mengtian”, all of which are T-shaped. As a long-term manned space laboratory, it can support the development of large-scale, multidisciplinary space science experiments, and will be equipped with scientific research experimental facilities related to biology, material science, basic physics, microgravity, fluids, etc. At the same time, more than 10 advanced scientific experiment cabinets, extravehicular load installation platforms, and common-orbit survey telescopes will be deployed to provide space science experiment conditions. Although the space station is operating in low-Earth orbit, the distance from the ground is only a few hundred kilometers, which is much closer than the distance from the Earth to the moon, Mars and other celestial bodies. However, it has entered into space and can obtain a microgravity environment, which provides a lot of research. The possibility. In a microgravity environment, the natural convection of liquid and gas caused by gravity is basically eliminated, the buoyancy in the liquid disappears, and the ups and downs and stratification caused by different material densities also disappear. Some common physical phenomena on the earth are no longer applicable. Here, water turns into droplets and can be played as table tennis. Therefore, the microgravity environment can carry out fluid physics research, including interfacial phenomena, multiphase flow, and complex fluids. Research in this field plays a very important role in the development of advanced space fluid management, thermal management and other aerospace technologies. For another example, atomic clusters will obtain different motion forms due to the disappearance of gravity. Scientists can use this change to test more accurate cold atomic clocks in space laboratories. Atomic clocks are the core components of Beidou and other satellite positioning systems. High-precision atomic clocks are expected to make satellite positioning more accurate in the future. In addition, it is possible to study material preparation under microgravity conditions: space materials science is a unique way to carry out material science research in depth, and it is possible to obtain advanced materials that are difficult to produce on the ground and important parameters that are difficult to accurately measure on the ground. Specifically, the research in this area is first to study the law of the preparation process of materials and the changes in the structure and performance of materials under the influence of gravity, and the second is the use of materials in space applications in high-energy particles and ultraviolet radiation, atomic oxygen erosion, and high and low temperature alternating cycles. Enabling behavior in a space environment. In June 2019, the China Manned Space Engineering Office and the United Nations Office for Outer Space Affairs jointly announced that 9 projects from 17 countries and 23 entities were successfully selected as the first batch of scientific experiment projects of the China Space Station. This is China’s manned spaceflight. For the first time, the project passed through the large-scale international cooperation of the United Nations. Russia began to withdraw from the space station. In April 1961, the Soviet Union launched the world’s first manned spacecraft, the “Vostok 1” spacecraft, and sent astronaut Gagarin into space. The next goal is how to let people “stay” and “stay long” in space. Ten years later, the Soviet Union successfully launched the world’s first space station “Salute 1”. After that, the Soviet Union began launching the Mir space station consisting of multiple cabins in 1986, consisting of a core module and 5 experimental modules, thus greatly expanding the space for astronauts and improving the working capabilities of the space station. The strength of the Soviet Union in this aspect has caused the United States to change its focus. Zheng Yongchun, a planetary scientist at the National Astronomical Observatory, said that throughout the 1980s, the exploration of the moon and Mars between the United States and the Soviet Union entered a low ebb, and the United States focused on the development of space stations. Pang Zhihao, a senior science author of space exploration technology, wrote that following the disintegration of the Soviet Union, in 1993, the United States undertook a “major operation” on its “Freedom” space station construction plan. The most important measure was to absorb Russia as a formal partner. Many of the mature technologies of the Soviet space station are designed to save costs, avoid detours, reduce risks, and shorten time. This is the predecessor of the International Space Station today. With its huge scale and cool appearance, the International Space Station has become a symbol of spaceflight in the contemporary world. It is an international space cooperation program, completed in 1998 by 16 countries after 10 years of joint construction, and the construction cost is as high as 150 billion U.S. dollars. On November 20, 1998, the first component of the “Dawn” functional capsule, funded by the United States and made in Russia, was successfully launched. In the following 10 years, the International Space Station expanded from 2 capsules to 15 capsules. It was not until 2010. The final construction is completed and transferred to the full use stage. The space station is the longest time-consuming, most involved, largest, and most advanced aerospace project in the world so far. It is mainly composed of the United States National Aeronautics and Space Administration, the European Space Agency, the Russian Federal Space Agency, the Japan Aerospace Exploration Agency, and Canada. Jointly operated by the Space Agency. On April 12, at a related work meeting held in Russia’s “Astronautical Festival”, Russian President Putin made the decision to formally withdraw from the space station project and set out to plan to build his own space station. Deputy Prime Minister Yuri Borisov said in an interview with the media that the operating life of the International Space Station has expired and its status is not satisfactory. “Recently, there are more and more news about technical failures. In order to avoid any risk in an emergency, a technical inspection of the space station is necessary. And we finally (made a withdrawal) decision and honestly issued an early warning to our partners. “The design life of the International Space Station was initially only 15 years, but in 2015, the space agencies of the United States and Russia reached an agreement and signed an agreement, agreeing to extend the life of the International Space Station from 2020 to 2024. Now it is the 23rd year of the International Space Station’s work. The long service period has severely deteriorated the performance of the space station’s equipment. The annual maintenance cost is as high as 5 billion US dollars, and it is still unable to repair the damage caused by the long service period. At the same time, Zheng Yongchun said that the space station and manned spaceflight are now slowly withdrawing from the United States, shifting its focus to Mars exploration, returning to the moon, and so on. “The National Aeronautics and Space Administration (NASA) wants to invest in Save the money in this area and leave it to commercial companies to do, because I think this part of the project is mature.” In the past 20 years, the United States has invested more than 100 billion U.S. dollars on the International Space Station. Such a huge expenditure is for NASA. Said that the pressure is not small. In order to operate and maintain the space station every year, the United States costs about 4 billion U.S. dollars, and NASA’s entire fiscal year budget is about 17 to 18 billion U.S. dollars. In 2018, the Trump administration began to gradually privatize the International Space Station and transfer it to private companies. It is planned that starting from 2025, the US federal government will stop providing any funds to the International Space Station. The United States has invested a budget of US$150 million in fiscal year 2019 to train commercial entities in the aviation sector to further develop and mature, so as to ensure that successors in the commercial sector have the ability to take over the space station at that time. The only space station in space After the decommissioning of the International Space Station in 2024, China’s Earth Space Station may be the only space station in space for a period of time. Pang Zhihao pointed out that manned spaceflight is a high-investment, high-risk, and high-tech systems engineering. So far, only Russia, the United States, and China have independently mastered manned spaceflight technology. The space station project is the third step of China’s “three-step” manned space project. In 1992, China’s manned space project was officially launched. The first step was to develop a manned spacecraft to achieve the goals of astronauts going back and forth between space and earth. The second step was to master the space laboratory phase, mastering the technology of exit, rendezvous and docking, and verify the propellant Rail replenishment technology to complete tasks such as transporting cargo replenishment. Since the first launch of Chinese astronauts into space by Shenzhou V in 2003, in the first two steps, China has successfully developed and launched 6 “Shenzhou” manned spacecraft, 2 “Tiangong” space laboratories and 1 “Tiangong” space laboratory. The “Boat” cargo spacecraft has sent 11 astronauts into space. These have laid the foundation for the third step-the construction of the space station. Among them, the space station mission is divided into three stages: key technology verification, assembly construction and operation. It is currently in the first stage: verifying the flexible solar cell wings through the launch space and core cabin, 2 manned spacecraft, and 2 cargo spacecraft. And driving mechanism, space station propellant and other technologies. Despite its long history, the space station still has a lot to do in the future. At present, the United States is cooperating with some countries to develop a lunar space station-the “deep space gateway”, which is expected to be put into use after 2024. The lunar space station can be used as a departure platform for manned spacecraft to the moon, asteroids and even Mars, as a relay communication platform for lunar rover, or as a transfer station for space telescopes on the L2 orbit of the Sun-Earth. “According to me, it is better to build China’s space station on the moon (orbit), so that manned landing on the moon will not be as difficult as the’Apollo’ (plan).” On January 13 this year, academician of the Chinese Academy of Sciences Ouyang Ziyuan, chief scientist of China’s lunar exploration project, said in a report that he once suggested that China skip the construction of the earth space station and directly build the lunar space station, which is more conducive to future manned moon landing plans. Ouyang Ziyuan believes that there have been decades of history from the Soviet space station to the International Space Station, and it is of little significance for China to build an earth space station. “People have done basically all important things for decades.” However, looking at the present, The launch of the “Tianhe” core module officially opened the prelude to the construction of China’s space station and is also an important milestone in the history of China’s manned spaceflight.

In the morning, I wrote a report in the dormitory and just entered the restaurant in the dark at noon, I heard the countdown sound of “…, nine, eight, seven…” on the TV, and suddenly thought that today is the launch day of the core cabin! After buying the meal in a hurry, I found a seat facing the TV and sat down, staring at the TV nervously, and mechanically delivered the meal to his mouth. At the moment when I lowered my head, I heard the overwhelming cheers from the general control room on the TV, and my mood suddenly relaxed. This kind of heartfelt cheers for our common cause feels so rare. It seems to have a kind of magic: it makes people go back to the childhood when we watched the rocket launch in front of the TV, which was for our various careers. Every little progress and ecstatic years. This is not to say that we don’t care about the country’s progress anymore, but to show that we have enough confidence to know that some things will eventually be achieved, some results will eventually be achieved, some stages will eventually be crossed, some goals will eventually be achieved, and some The society will eventually be built! We are all bowing our heads. Today, when the international situation is complex and the economic situation is not optimistic, the depression in our hearts has been held back for too long: we have been isolated and besieged by sanctions, slander, and isolation. We need an event to boost people’s hearts so much that we have to shout out: China nb~Wuhu take off! On the way to bow down and forge ahead, you must also look up at the stars and the sea, right?

Successful entry into China’s aerospace industry uses strength to interpret what is perfect. At present, the Tianhe core warehouse is currently the heaviest single spacecraft (ISS is a combination) among all mankind’s orbiting spacecraft. It is also the only orbital load exceeding 20 tons (space shuttle body) launched by mankind since entering the 21st century. (Not counting the payload) is also the most complete, advanced, and most powerful space station bin segment, far exceeding the ISS bins. At the same time, it is also the first space station warehouse section to use electric propulsion. It marks that our country has completely become the first echelon in aerospace that keeps pace with the United States and far surpasses Russia, Japan and Europe. If two years after the completion of the first phase of the components, the Tianhe reserve warehouse is relaunched, and the second phase is formed, then CSS will become the strongest bluestar space station with more complete functionality, higher power, and more advanced equipment than the ISS. Cold knowledge Tianzhou cargo spacecraft is currently the bluestar cargo spacecraft with the strongest carrying capacity, far surpassing NASA cargo dragon, Cygnus, and Jaxa’s HTV

2021-04-29 11:38 has been successfully launched! Strictly speaking, it is of little significance to China’s aerospace, and has a very significant and far-reaching significance to the development of China’s basic science. The reason is that our space station is essentially a “China National Space Laboratory.” You know, the laboratory, it’s used for experiments. The significance of China’s manned spaceflight revolves around the construction of laboratories, and the three steps are all for the third step. And this space station will greatly promote the development of basic scientific research in our country and narrow the gap with the international advanced level. You may not feel that countries like the United States, Russia, Japan, and Canada have done experimental research in microgravity-related sciences for almost two decades. In addition, the early days of the sky laboratory, the salute series, the Mir space station, etc., have accumulated profound accumulation. There is a huge gap between our level and their level, and we urgently need to catch up without delay. It is foreseeable that my country will make major breakthroughs in basic science research in the next ten years. What are the unique conditions of this laboratory? What experiment will you do? What kind of experimental equipment is there? How will this laboratory be built in the future? I will output a series of videos to explain to you.
