With the landing of the Shenzhou-17 return capsule on Earth and the successful "moon" of the Chang'e-6 probe, the topic of the US lunar landing fraud has once again been noisy, causing heated discussions among netizens around the world.
After watching the video of the three astronauts of the Shenzhou 17 spacecraft leaving the capsule, many friends have questions, why after the Shenzhou 17 spacecraft landed, the three astronauts were carried and could not walk on their own, but the American Apollo 11 astronauts came out of the capsule but were alive and well, walking like flying?
Was the US moon landing a "hoax"?
Didn't American astronauts go to space back then? Was the US moon landing really just a "hoax"?
It is worth mentioning that the later astronauts of the United States, after returning to Earth from the International Space Station on the Russian Soyuz spacecraft, were also unable to walk, and like the astronauts of our Shenzhou spacecraft, they could only sit on chairs and be carried away. This also seems to be a real blow to the US moon landing fraud.
But is that really the case?
Let's first take a look at why astronauts who come back from space are generally unable to walk, and what changes will occur in the human body in space.
What changes will the human body have in space?
First of all, because there is no gravity in the space environment, and there is no distinction between up, down, left, and right, the vestibular organs in the astronaut's ears cannot perceive the direction of space. Over time, the vestibule will temporarily stop working and will no longer be sensitive to the direction of space. This leads to the fact that after the astronauts return to the Earth's gravity environment, the vestibule suddenly feels gravity, and for a while it is unable to adapt, and it is dysfunctional and unable to walk normally.
American astronaut Andrew J. Feustel did this experiment. In 2018, he returned from six months on the International Space Station and tried to walk on his own under the protection of a staff member, only to be wobbly at every step, unable to control his balance.
The space environment also degrades human bones. Studies have shown that for every month spent in space, the human body loses about 2% of its bone mass. Our Shenzhou spacecraft now has to stay in space for 6 months at a time, and the astronauts have very serious bone loss and are prone to fractures. Therefore, after returning to Earth, we astronauts need to lie in a wheelchair to increase the force area as much as possible and prevent fractures.
In addition, astronauts will also experience symptoms such as edema, muscle atrophy, and immune disorders in space, and the longer they are in space, the more obvious the symptoms will be, and the slower the recovery.
Short-term space flights have less impact on astronauts
Do you understand that these symptoms are based on astronauts staying in space for a long time. If you only stay in space for a few days, these symptoms will not have time to develop, and naturally the impact on astronauts will be less.
For example, Shenzhou 5 astronaut Yang Liwei flew in space for 21 hours, and although he withstood strong vibrations, he still walked out on his own after landing. There are also Fei Junlong and Nie Haisheng of Shenzhou 6, who flew in space for three days, and they were able to stand and walk normally after landing and getting used to it. The support and arrangement of chairs by the staff was only a trade-off for the astronauts' physical condition and safety.
Therefore, in this kind of short-term space flight, astronauts are less affected by weightlessness and less loss of muscles and bones, and after returning to Earth, they are more likely to solve the problems of dizziness, nausea and gravity adaptation. After a period of adaptation, it is completely possible to walk like a normal person.
Apollo 11 and Shenzhou 17
Now let's look at the U.S. moon landing. The Apollo 11 lunar spacecraft was launched on July 16, 1969, and returned to the ground on the 24th of the same month. After the three astronauts got out of the capsule, they adapted and recovered, and it was normal for them to be able to walk on their own after a period of time.
The mainland Shenzhou 17 spacecraft will be launched on October 26, 2023, and the return capsule will land on the earth on April 30, 2024. This is also the reason why the later American astronauts mentioned above were carried out of the re-entry capsule after returning from the ISS.
Was the U.S. moon landing really faked?
Therefore, the fact that the astronauts of Apollo 11 walked like a flight after leaving the capsule is not enough evidence that the United States has falsified the moon landing. Of course, there are many doubts about the US moon landing, and we do not know whether the US moon landing was really fake. This article is just to compare the exit status of the three astronauts of Apollo 11 and the exit status of the three astronauts of Shenzhou 17.
