The return process of Shenzhou 16 has attracted a lot of attention and discussion, especially during the landing, there were some unusual situations, including dust rising and the return module rolling several times. But in fact, these situations do not mean that the mission has failed and the astronauts have safely returned. This article will explain the reasons for these phenomena and the continuation of the Shenzhou 17 mission for you.
Let's delve deeper together, grasp the pulse of this ever-changing world, and jointly promote the construction of a community with a shared future for mankind.
Latest news 1: Shenzhou 16 failed to return? Netizens have noticed that it has rolled several times and dust is rising everywhere. What is the reason?
The return mission of Shenzhou 16 has sparked widespread discussion and attention during the landing process. Many netizens saw in the video footage that the entire landing process was accompanied by dust flying around and a brief rolling of the return capsule. This scene has sparked people's doubts, some even questioning whether this was a failed return mission. However, we need to gain a deeper understanding of the complexity and reasons behind this process in order to understand the truth behind it.
The return mission of Shenzhou 16 is undoubtedly full of challenges and dangers. Not only for this mission, all manned spacecraft in China have experienced similar extreme conditions when returning, and it is necessary for the Chinese Space Center to ensure that every step reaches the ultimate perfection and ensure the safety of astronauts.
In the return mission, a "fast return plan" was adopted, reducing the number of circles around the Earth from 11 to 5, shortening the return time but also increasing the difficulty of technical requirements. The most critical and thrilling moment is at an altitude of approximately 100 kilometers from the ground, when the re-entry module rushes into the atmosphere at a speed of about 7 kilometers per second, causing extreme friction with the atmosphere, making the re-entry module like a fireball crossing the sky.
At an altitude of 80 to 40 kilometers, a plasma shell will form around the return module, causing radio communication between the ground and the return module to be interrupted. This stage is also known as the "black barrier zone". Within the blackout zone, the speed of the return capsule sharply decreased. By the time it left the blackout zone, the speed had already dropped to about 200 meters per second, equivalent to over 700 kilometers per hour.
Despite continuous deceleration, the return capsule experienced a large-scale deceleration again at an altitude of approximately 10 kilometers, entering the "parachute" phase. The opening of a parachute is divided into three stages, followed by a guide parachute, a deceleration parachute, and finally a main parachute. After the main umbrella was deployed, the area reached 1200 square meters, and the descent speed of the return module decreased to 7 to 8 meters per second. At an altitude of approximately 6 kilometers, the return module will discard the heat resistant bottom and enter the safe landing phase through a reverse thrust system. This process is a great test for China's aerospace technology and also indicates that the entire return mission is much more difficult than people imagine.
During the mission of Shenzhou 16, there was a situation where the return module rolled over during landing, which raised some doubts. But it should be clear that this does not mean the task has failed. All astronauts returned safely without any adverse effects. This situation may be caused by multiple factors.
Someone may have noticed a large amount of dust after landing. This is because the structural characteristics of the Shenzhou spacecraft, especially when landing in desert areas, can trigger this phenomenon. The Shenzhou spacecraft adopts a three module, one section structure, including a return module, orbital module, propulsion module, and additional section, with a total of 13 subsystems. When the re-entry module lands, four landing thrust engines are equipped on the anti heat bottom at the bottom. In order to achieve a safe landing, these engines must start and ignite simultaneously, generating strong thrust and igniting dust on the ground, which is a normal phenomenon.
Despite some seemingly abnormal circumstances, the mission of Shenzhou 16 did not fail, and the astronauts were safe and sound. These situations can be explained as normal technical challenges and complex landing conditions. Next, the Shenzhou 17 mission will continue to be carried out. Tang Hongbo, Tang Shengjie, and Jiang Xinlin, the three astronauts, will face a highly challenging task of repairing damaged solar wings. This is China's first attempt at a mission that will provide valuable experience for future space station expansion. This mission is expected to be successfully completed, accumulating more experience for the continuous development of China's space technology.
Although this task is full of high difficulty challenges, it does not mean failure. For China's aerospace industry, this is a valuable opportunity to continuously accumulate experience and promote technological progress. For this task, we will wait and see what achievements it will achieve.
Latest News 2: Wide bodied passenger plane, Russia took off first, did not choose CR929, China needs to completely rely on itself
Russia has successfully achieved the first flight of the Il-96-400M wide body aircraft, which has had a significant impact on the global aviation industry and the large aircraft market, although it has not attracted widespread attention in some international news contexts. This marks a new breakthrough for Russia in the field of large aircraft, despite facing some challenges and technological backwardness. The first flight of the Il-96-400M wide body aircraft was supposed to be completed in 2021, but due to project progress and other factors, the first flight was postponed to the end of 2023. This aircraft is a wide body passenger aircraft produced by the Irkutsk Aircraft Manufacturing Plant in Russia. It is the fourth generation model of the Ir-96 series and the most advanced version. Although the Il-96 series has been in operation since the 1980s, its sales performance has been poor and its popularity is low. Apart from being a special plane for Russian President Putin, few people know about it.
Compared to previous models, the Il-96-400M has increased its fuselage length by more than nine meters, with a maximum passenger capacity of 370 people, equivalent to wide-body aircraft in the Boeing 777 and Airbus A350 class. However, unlike these competitors, the Il-96-400M uses four engines, while the Boeing 777 and Airbus A350 have dual engine designs. Although the four engine design of the Il-96-400M was reasonable in the 1980s, it appeared relatively outdated in the design of large aircraft in the 2020s. This design has led to insufficient competitiveness of the aircraft in the international market. Russia faces external and internal challenges. External factors include sanctions imposed by Western countries on Russia, making it difficult for Russia to import large aircraft and maintain its Western fleet. Internal challenges include Russia's economic difficulties and outdated aviation manufacturing technology since the collapse of the Soviet Union. To ensure the normal operation of domestic commercial transportation, Russia can only choose to independently manufacture the Il-96-400M.
At the same time, the CR929 project in China Russia cooperation has encountered difficulties. The project aims to develop a long range wide body passenger aircraft, jointly developed by COMAC and the Russian Joint Aviation Manufacturing Group. However, Russia withdrew from the project mainly because it was unable to meet China's technical requirements for CR929. This setback proves the importance of key technologies, which cannot be achieved solely through purchase and must be obtained through independent research and development.
Although Russia has withdrawn from the CR929 project, COMAC still plans to continue research and development, only renaming the project as C929. China will not lower its requirements for key technologies such as engines, but will seek independent research and development. This indicates China's ambition and determination in the field of large aircraft. The first flight of the Il-96-400M wide-body aircraft marks Russia's progress in the manufacturing of large aircraft, but also highlights challenges and competition. In the competition of the global large aircraft market, technological innovation and independent research and development will become key factors. For the C929 project, we look forward to China achieving independent research and development in the future and achieving success in the fiercely competitive field of large aircraft in the international market.
From a technical and market perspective, the first flight of the Il-96-400M signifies that Russia is seeking to regain competition in the field of large aircraft manufacturing. However, its four engine design is not very popular in the global market, which may pose certain constraints on its market competitiveness. At the same time, the C929 project in China is still ongoing, and COMAC has stated that it will adhere to independent research and development, which will add new variables to future competition in the large aircraft market. For China, the success of the CR929 (now C929) project will strengthen its position in the field of large aircraft manufacturing and provide strong support for the future development of the aviation industry.
The manufacturing of large aircraft is a massive project that involves complex technological and market challenges. The first flight of the Il-96-400M and the continued development of the C929 project will have a profound impact on the global aviation industry. This development also reminds us that aviation manufacturing must be based on independent research and innovation to respond to constantly changing market demands and technological challenges. Both from Russia and China need to be fully prepared for the competition in the large aircraft market.
Latest news 3: NATO natural gas pipelines and cables have broken, planting China and meeting the conditions for war
Recently, a puzzling news came that Estonia had requested China's help to investigate a communication cable rupture incident that occurred in the Baltic Sea. This incident seems unrelated to China, but what raises questions is why we seek China's help? Further analysis may reveal more insider information.
This year, the "Baltic Connector" natural gas pipeline and a communication cable connecting Finland and Estonia were damaged. The Finnish authorities suspect that this may be an intentional sabotage incident, although the cause of the damage is currently unclear. Finland and Estonia are collaborating on a joint investigation, however, the matter has not yet been finalized, and there have been attempts to link it with Russia. According to Reuters reports, the pipeline connects Finland's Inku and Estonia's Padisky, crosses the Gulf of Finland, enters Russian territorial waters, and ultimately arrives at the port of St. Petersburg. Although this area is located on the sea passage of St. Petersburg, attempting to implicate China in this incident seems somewhat farfetched.
Data shows that before and after the incident, the "New New Polar Bear" under the Hong Kong Special Administrative Region of China and the "Sevmorput" under the Russian flag appeared near natural gas pipelines and damaged submarine cables. Finnish investigators are investigating these two ships. The Estonian government has maintained contact with China and expressed encouragement for any necessary investigation cooperation. However, there was no connection established with Russia. This seems to imply suspicion that China is related to Russia, but it is worth asking why this pot was thrown at China? There are many ships passing through the Baltic Sea region, so it seems a bit farfetched to hastily point suspicion at China. Ship tracking websites can only monitor ships with transponders activated, and cannot cover all situations. In addition, if underwater submarines or unmanned submersibles are used for destruction, it is difficult to leave traceable traces. Many countries' military vessels and aircraft do not activate transponders, making it difficult to track them. Therefore, it is not realistic to attempt to speculate solely on the mastermind behind the scenes.
It is worth noting that Norway's submarine cables have also been damaged before, connecting Europe and the Arctic Ocean, causing significant impacts on fields such as communication, finance, and aviation. However, the truth of the incident has not yet been determined. These consecutive incidents of submarine cable damage have attracted high attention from European countries, but their targeting of suspected targets seems too hasty.
Against this backdrop of uncertainty, some countries seem to be actively seeking to become embroiled in conflicts and further escalate tensions, and such actions may only bring more risks to global peace and security. The conclusion drawn from these events is that for the international community, how to respond to these events requires a more calm and rational analysis to avoid unnecessary deterioration of the situation. Impulsive remarks and accusations may not help solve the problem, but may make the situation more complex.
