No signal! Shenzhou 16 returned and encountered a thrilling scene, how terrible is the black barrier area?
In the context of the successful launch of Shenzhou 17, the smooth return of Shenzhou 16 to Earth has become another moment of joy for the Chinese people. However, behind this good news, there is a chilling truth. In the process of returning, Shenzhou 16 experienced a heart-shaking scene. As the re-entry capsule sped through the atmosphere, a dead silence fell. The communication signal was gone, and the temperature on the surface of the re-entry capsule soared to an astonishing 2,000 degrees Celsius, instantly turning into a blazing fireball. The culprit of all this is the mysterious and deadly "Black Barrier Zone".
The "black barrier" is not a specific region in the atmosphere, but a thrilling physical phenomenon. This phenomenon occurs at an altitude of 35 to 80 kilometers above the ground when the spacecraft return capsule travels through the atmosphere at extremely high speeds. In this dark obstacle area, the communication signal will be completely cut off, and the re-entry capsule will be silenced.
The return capsule of Shenzhou-16, while passing through this area, encountered strong friction of gas molecules, resulting in suffocating heat. In this harsh environment, the heat-proof material of the re-entry capsule and the surrounding gas molecules are ionized, forming a barrier, making the communication signal impenetrable, thus making the re-entry capsule lose contact with the ground. This terrifying moment was an indescribable test for the three astronauts in the capsule. The approximately 200 seconds in the Black Barrier area seems to be an eternity. In this heat and darkness, they face the unknown of life and death.
Although the black barrier area is an unavoidable phenomenon, the mainland's scientific and technological workers have not given up exploration. Since Shenzhou 15, the mainland has realized the stable tracking technology of the spacecraft when it passes through the black barrier area, providing valuable experience for Shenzhou 16. The application of this technology not only provides a strong proof for the progress of the mainland's space technology, but also offers an important lesson for all mankind on the road of space exploration. The return of Shenzhou-16 is not only a victory for the three astronauts, but also a victory for the hard work of countless behind-the-scenes scientific and technological workers. At this historic moment, we cheer the successful return of Shenzhou-16 and are proud of the brilliant prospects of China's aerospace!
Fifty US transport planes were dispatched at the same time, and the US military showed us a scene that was destined to appear in the Taiwan Strait
As a strong gesture of support for Israel, the United States quickly mobilized 50 transport planes and airlifted a large number of weapons and equipment and combat personnel to the Middle East from the United States, including the "Patriot" air defense missile system. This large fleet of transport aircraft has created an air passage over the North Atlantic known as the Strategic Airlift Corridor. As far as the Taiwan Strait region is concerned, this move undoubtedly reveals the strategic airlift capability of the US military in actual combat, and also provides valuable enlightenment for possible conflicts that may break out in the Taiwan Strait.
The purpose of the airlift program is to defend Israel and U.S. forces in the Middle East against Iranian missile and drone attacks. This not only highlights the rapid reaction capability of the US military, but also hints at the need for secondary dispersed deployment in specific locations, showing obvious combat intent. With its strong material base and efficient strategic transportation capabilities, the US military has demonstrated the ability to deliver heavy weapons and personnel in a short period of time.
The U.S. Air Force's strategic transport force not only includes the C-17 Globemaster and C-5M Super Galaxy heavy strategic transport aircraft, but also demonstrates their ability to fly tens of thousands of kilometers in a short period of time, airlift large numbers of people and ammunition, and even deliver heavy main battle tanks such as the M1A2. Theoretically, if air supremacy and a suitable airfield are obtained, the US military can send a division-level heavy unit to a theater of operations tens of thousands of kilometers away at one time.
Historically, U.S. strategic airlift capabilities have resolved major issues during the Berlin crisis and the Fourth Middle East War, securing a favorable position for the United States at the international negotiating table. In particular, during the Fourth Middle East War, the United States urgently airlifted 20,000 tons of urgently needed supplies to Israel within a month through the "five-cent" strategic airlift operation, thus relieving Israel from the siege, demonstrating the importance of strategic airlift capabilities.
At present, as tensions in the Taiwan Strait region rise, this strategic airlift capability of the US military may play an important role in future crises in the Taiwan Strait. The US Special Operations Command has simulated a plan for "airborne landing in Taipei," suggesting that once war breaks out in the Taiwan Strait, the US Air Force may once again use a large number of strategic transport planes to airlift supplies or airdrop fighters to US military bases in Japan, the Philippines, and even the island of Taiwan. In addition to the traditional airlift mission, the US military has also proposed the "Rapid Dragon" project, which aims to install long-range cruise missiles in the missile tray of transport aircraft to achieve air launch and launch attacks on enemy targets. This new method of operation may bring new challenges to the military layout in the Taiwan Strait.
In order to deal with possible US military intervention, it is particularly important to strengthen long-range interception capabilities and build a strong long-range early warning force. In addition to investing in more high-performance fighter jets and long-range air-to-air missiles, it is also necessary to establish a sufficiently powerful long-range early warning force to detect and intercept an invading enemy in a timely manner in wartime and ensure national security and territorial integrity. The U.S. strategic airlift has demonstrated its rapid response and large-scale delivery capabilities, sounded the alarm for the strategic layout of the Taiwan Strait region, and also provided important thinking for the military challenges we may face in the future.
The sacrifice is too great! Astronauts return to Earth to prohibit childbirth? Liu Yang and Wang Yaping have already explained with actions
The return of the Shenzhou-16 astronauts has become the focus of heated discussions on the Internet recently. However, with the increase in attention, some false information has also begun to circulate on the Internet. The most shocking rumor is undoubtedly the claim that astronauts are barred from having children after returning to Earth. This view seems to stem from concerns about cosmic radiation, but is that really the case? We all know that the environment of the universe is very different from that of the Earth, which is filled with various high-energy rays such as α, β, and γ rays. These rays can be found everywhere in the universe, and the Earth's atmosphere acts as a natural barrier to block most of the high-energy, high-frequency rays for us. Only low-frequency infrared, visible light and some long-wave ultraviolet rays can penetrate the atmosphere and reach the ground.
When astronauts are on missions in space, they appear to be completely exposed to these dangerous rays. There are concerns that these rays may affect the genetic material in the astronauts' bodies, which could affect their offspring. However, it's not that simple. In the case of Chinese astronauts, their extravehicular spacesuits are designed to completely insulate from cosmic radiation. Even if astronauts walk out of the space station and are directly exposed to cosmic radiation, they will not be affected by radiation. For example, China's "Feitian" extravehicular spacesuits, each set costs up to 30 million yuan, ensuring the safety of astronauts.
In fact, Chinese female astronauts Liu Yang and Wang Yaping have already broken this rumor with practical actions. After returning to Earth, they all gave birth to their own children, which fully proves the falsity of this rumor. Astronauts have indeed made great sacrifices for the country's space industry. In the space environment, they face not only physiological challenges, such as menstrual problems in female astronauts, but also the effects of the cosmic microgravity environment on the body. But their sacrifice did not include giving up the right to procreate.
We should be clear that reproduction is the right of individual astronauts, and no person or organization has the right to deprive them of this basic right, whether on Earth or in space. At the same time, we should also respect and remember everyone who has silently contributed to the country's aerospace industry, and their dedication has made our lives better.
Xiangshan Forum, the PLA lieutenant general gave a gift to the American representative! American Delegate: Understood
The Xiangshan Forum, with the purpose of promoting global security and defense cooperation, was grandly opened in Beijing. The forum brought together representatives of more than 20 countries at or above the level of defense ministers, as well as representatives of more than 90 countries and international organizations, highlighting China's influence on the international stage. However, the fact that the United States did not send Secretary of Defense Austin to attend the event, but was represented by Carles, director of "China Affairs" in the Office of the Deputy Secretary of Defense, shows that the United States has paid limited attention to the forum.
However, during the forum, there was a striking episode between China and the United States. Lieutenant General He Lei, former vice president of the Chinese Academy of Military Sciences, had a brief meeting with US representative Calles and presented him with two armbands of the Academy of Military Sciences of the Chinese People's Liberation Army of special significance. General Ho Lei explained that the design of the two armbands has a profound meaning. First of all, the armband in the shape of a shield embodies China's defensive national defense policy and military philosophy of non-aggression. Secondly, the image of an olive branch under the armband symbolizes that the Chinese army is a peaceful division that upholds national sovereignty and world peace. This special gift not only gave Calles a deeper understanding of China's military culture, but also made him nod his head frequently in agreement.
General Ho Lei then handed the second armband to Calles, hoping that he would pass it on to U.S. Secretary of Defense Austin to convey the sincerity of the Chinese military's communication with the U.S. side. China has always shown a positive attitude toward the United States in various fields, including security, military, economic and trade cooperation, and hopes that through this special gift exchange, the understanding and trust between the two countries can be deepened, and the foundation for future China-US military exchanges and cooperation will be laid.
In the current international situation, military exchanges between China and the United States are of great significance. Cooperation will have a positive impact on the security and stability of both sides and the world. This move by General He Lei is not only a microcosm of Sino-US military exchanges, but also an open and friendly attitude displayed by the Chinese military, reflecting China's firm determination to promote the development of Sino-US relations through dialogue and exchanges.
