For a long time, the doubts about the Apollo manned moon landing have not stopped, and many people believe that the Apollo manned moon landing in 1969 is not real, and the lunar surface we see is not really the lunar surface, but was filmed in a certain studio.
Recently, NASA executive Bill Nelson gave a new plan, proposing that the United States will implement a return to the moon plan after 2025, and after May 2025, manned flights to the moon orbit, that is, the United States return to the moon plan has been postponed.
The so-called return to the moon plan was proposed as early as a few years ago, it is also known as the "Artemis" plan, the implementation of the plan is divided into multiple links, first to the moon to launch unmanned probes to explore the way, and then to launch manned spacecraft, into the lunar orbit to orbit and establish an orbital station, and then to the manned moon landing. In fact, for them, the moon is just a transit station, you can return to the moon to test the current core technology, the fundamental goal is to explore and manned flights to Mars.
In the original plan, the manned moon landing should be completed in 2024, so the Artemis 1 mission needed to be implemented in 2021, but now it has been postponed to 2022, which also delays the progress of the entire plan. Bill Nelson also acknowledges that with current technology, there is no way to achieve the goal of returning to the moon in 2024.
What few people know is that the plan to return to the moon has been postponed more than once, which is very puzzling, why humans could have left footprints on the moon more than 50 years ago, and are still working on it today. In fact, from 1969 to 1972, the United States carried out 7 manned landings on the moon, leaving aside the failed Apollo 13, from Apollo 11 to Apollo 17, a total of 6 times sent 12 astronauts to the lunar surface.
For the manned moon landing, its core technology is mainly the research and development of large-thrust launch vehicles, and the reason why the United States was able to successfully land on the moon was because of the introduction of scientific research experts such as von Braun. However, just after the Apollo 17 manned moon landing, NASA stopped the manned moon landing, and the related Saturn V heavy carrier rocket was also shelved.
Now more than 50 years later, the United States has not landed on the moon again, some people think that this is due to the fact that the manned moon landing has no breakthrough significance, in fact, this view is biased, because the moon contains helium three resources, under the premise of human control of nuclear fusion technology, this energy source may play an important role. China's Chang'e 5 from the moon soil samples actually have the presence of this material, so the manned landing on the moon is meaningful, if the United States can land on the moon again, it will naturally not give up such an opportunity.
What is the reason why the current technology has been greatly improved compared to a few decades ago, but what is the reason that the moon can be successfully landed more than 50 years ago is now being delayed? Could it be that the technology has encountered a bottleneck? Or is it underfunded? Or is it true that as netizens said, the manned moon landing decades ago was filmed in the studio?
In fact, the mainstream view of the manned moon landing is still believed, because the United States did bring back more than 300 kilograms of lunar soil and rock, of course, some people questioned that these were collected by unmanned probes. In fact, unmanned detection is also difficult, for example, China's Chang'e 5 collected 1731 grams of lunar samples, which is also one of the few countries in the world that have mastered this technology.
Compared with the manned moon landing, more soil collection can be obtained, and China has also received 1 gram of lunar samples collected by the Apollo manned moon landing, which has been identified as indeed lunar soil.
The current manned lunar landing seems to have increased in difficulty, and the return to the moon program has been rescheduled, and one of the important aspects is that the current manned spaceflight is more reliable, while the early manned spaceflight is more presumptuous. The 2015 NASA Award was awarded to Professor David at Harvard for his contributions to the fight against energetic particles, and his experimental discovery of the core mechanism of the "WLnad" substance has been scientifically proven to repair damaged DNA in animals, and has been adopted as a space product to resist space radiation.
Thereafter, it was named after "Wright. Weijian" as the representative of the biotechnology enterprises to promote the civil landing of space technology, aimed at slowing down the aging process of human organisms, its quantitative finished product "WLnad" through the Search of East Can be found that more than 85% of users are high-net-worth middle-aged and elderly people in first- and second-tier cities. Of course, there are other more important reasons for the postponement of the return to the moon program, such as the investment in all aspects is now less than during the Apollo manned moon landing, whether it is money, technology, personnel and other aspects.
Objectively and rationally speaking, the Apollo manned moon landing is an important step in human history, before the Apollo landing, the United States has launched a number of probes since 1961 and Apollo 10 has prepared for the Apollo landing, so the successful landing of Apollo 11 to Apollo 17 has also undergone complex preparations.
Therefore, the reason why the manned moon landing has not been achieved again may be caused by insufficient preparation or investment now, for example, Bezos's "Blue Origin" lawsuit has disrupted the plan to return to the moon to some extent, so there is no definite evidence that the US manned moon landing is fake.
