Why Chinese Astronauts Lie Down When Exiting the Capsule? The Truth is Not Inferiority
On November 4th, early in the morning, the Shenzhou-18 spacecraft successfully completed its mission and landed safely. However, when the astronauts exited the capsule, they were carried out by staff, sparking heated discussions among netizens. Some compared this to American astronauts who were able to walk out of the capsule themselves after landing, questioning the competence of Chinese astronauts. But the truth is not that simple. Chinese astronauts lying down when exiting the capsule is not a sign of "inferiority," but a way to protect their health.
Space Exploration: A Necessary Step for Human Survival
As Earth's resources become increasingly scarce and the environment worsens, countries around the world are joining the ranks of space exploration. Exploring space is not only driven by human curiosity but also by the search for a "second home" for humanity's long-term survival. However, space remains an unknown realm for humans, full of challenges and risks.
Human Spaceflight: A Highly Technical Challenge
Sending humans into space is the ultimate goal of human spaceflight programs. Unlike ordinary rocket launches, human spaceflight requires overcoming enormous technical hurdles and safety risks. Currently, only three countries have achieved human spaceflight: the United States, Russia, and China.
The American Moon Landing: A New Era of Space Exploration
In 1969, the United States, with its Apollo spacecraft, succeeded in sending astronauts to the moon, ushering in a new era of human space exploration. This achievement shook the world and gave the United States a leading position in the field of aerospace.
Chinese Spaceflight: Catching Up and Achieving the Dream of Human Spaceflight
Despite lagging behind the United States in its early development, China has always held the dream of exploring space. After years of effort, China successfully launched the Shenzhou-5 spacecraft in 2003, with Yang Liwei becoming the first Chinese astronaut to enter space, realizing China's dream of human spaceflight.
Differences in Exit Methods Between Chinese and American Astronauts: Not a Matter of "Inferiority"
However, the differences in exit methods of Chinese and American astronauts after returning to Earth have attracted public attention. American astronauts were able to walk out of the capsule on their own, while Chinese astronauts had to be carried out lying down. Does this mean that Chinese space technology is inferior to that of the United States? Not at all.
The Impact of Microgravity Environments on the Human Body: Osteoporosis, Muscle Weakness
Astronauts in space are in a state of microgravity for extended periods, which can have significant effects on their bodies, including osteoporosis, muscle weakness, and disruption of the circulatory system. If they immediately walk on Earth after returning, it could lead to serious consequences.
The "Adventure" of American Astronauts: Lack of Experience, Short Duration
In the early days, American astronauts were able to walk out of the capsule on their own because they were the first country to achieve human spaceflight, lacking experience and reference cases. Additionally, their spaceflight durations were shorter, resulting in relatively less impact on their bodies.
Safety Guarantees for Chinese Astronauts: Lying Down to Exit, Protecting Health
Chinese astronauts often stay in space for longer periods, facing greater impacts from the microgravity environment. To guarantee the safety and health of astronauts, Chinese researchers have accumulated considerable experience and chosen the lying-down exit method, helping astronauts gradually adapt to Earth's gravitational environment.
Scientific Basis for Lying Down to Exit: Adapting to Earth's Gravity, Preventing Risks
Astronauts in space are in a state of microgravity for long periods, causing changes in the circulatory system, with blood flowing upwards, concentrating in the upper body, especially the head. This change can lead to symptoms like head swelling, increased eye pressure, headaches, nausea, and even affect cardiovascular health.
Development of Chinese Space Technology: Emphasizing Safety, Guaranteeing Astronauts' Health
In the development of space technology, China has always prioritized the safety of its astronauts. The lying-down exit method is not a sign of "inferiority" but a consideration for the health of astronauts. The development of Chinese space technology is not just about speed and efficiency, but also about safety and safeguarding the health of astronauts.
Conclusion: The Future of China's Space Program
The development of China's space program not only provides a new perspective for humankind's exploration of the universe but also makes significant contributions to the advancement of human civilization. Chinese space explorers will continue to strive and break through technical bottlenecks, opening up new paths for humanity's space exploration!
