Human beings always strive to be the "first" in many fields, the first place in the student era, the champion in the competition, the first person to climb Mount Everest, etc. In the space industry, there are also many countries striving for the first place, in order to express the strength of their national strength and the development of science and technology, which is one of the reference conditions for improving international status and competitiveness in international relations.
There is no doubt that the United States and the Soviet Union have been ahead of the world in this regard due to the early start of space research programs. When mankind first landed on the moon, it was a world-renowned event, and Apollo 11 and the three astronauts who landed on the moon in a spacecraft also achieved a great innovation in human history.
But it may be exactly the answer to the phrase "people are not too many", especially when some things that are originally very unlikely or impossible become true, and there will be more right and wrong.
In the technological environment at that time, many people did not think that human landing on the moon could be achieved. Therefore, the news of the successful moon landing of Apollo 11 has attracted much attention, and at the same time, it has also faced great doubts.
<h1 class="pgc-h-arrow-right" data-track="5" > the Apollo 11 moon landing program</h1>
Apollo 11 is nasa's fifth manned mission in project Apollo and the first human mission to the moon.
From the first manned lunar flight program proposed in 1961 until the successful completion of the sixth lunar landing program in late 1972, the United States spent a total of 11 years and more than 300,000 people contributed to the program. In this program, which has devoted almost all the researchers' efforts, every participant has done their best, and some have paid with their lives (the three Apollo 1 astronauts died in a fire during a rehearsal).
By 1968, NASA had finally begun experimenting with the first manned flight with Apollo 7 after several orbital flight tests. By the time Apollo 8, 9 and 10 had undergone different manned flight test missions, and then to the successful Apollo 11 moon landing, more than one million people had gathered at the launch site at that time, and the audience watching the live broadcast around the world had set a new record, reaching 600 million people.
Later, astronaut Armstrong landed on the moon and uttered the words that the whole world was listening to:
This is a small step for me personally, but a big step for all of humanity.
<h1 class="pgc-h-arrow-right" data-track="9" > moon landing questions</h1>
When Apollo 11 landed on the moon, it finally returned to Earth, bringing back a lot of unknown information about the moon and correcting many human misconceptions about the moon.
But with it, there are many malicious controversies and questions, which they believe that is the US NASA fraud, the biggest scam of the 20th century, and call the moon landing program "Apollo Moon Landing Conspiracy Theory".
Among them, there are 18 main questions, including flying flags, starsless skies, the presence of multiple shadows and clear shoe prints, and the authenticity of the moon rocks brought back. Some of the questions were discussed, and even the relevant "evidence" was cited, and many expatriates had strong doubts about the success of the moon landing.
Rumors such as the rocket's destination in Antarctica, the moon landing film being a documentary filmed in a greenhouse, and other rumors have been endorsed by many people, and some filmmakers have made a series of movies that specifically talk about the contradictions in his moon landing plan, and even argue with aldrin, an astronaut involved in the moon landing.
Until now, it seems that every time there is news of a human spacecraft landing on the moon, the true or false question of the Apollo 11 moon landing in the United States will still be turned over.
<h1 class="pgc-h-arrow-right" data-track="15" > Chang'e 5 landing on the moon</h1>
Chang'e 5, developed by the China National Space Administration, is China's first lunar probe to return from unmanned lunar surface sampling, marking the end of China's lunar exploration project.
On November 24 last year, Chang'e 5 lifted off, successfully entered the scheduled orbit, and successfully landed on December 1 in a preselected area near a crater on the pre-selected lunar front (the lunar front is relatively flat overall, and the back side is mostly a crater with a bumpy crater). Three days later, Chang'e 5 had finished sampling the moon and completed its lunar mission. On December 3, Chang'e 5 left the moon with samples and successfully returned to Earth in the early morning of the 17th.
First of all, this is an extremely difficult lunar mission, because this is the first time that Chinese spaceflight has prepared and realized unmanned sampling and return work on the moon. For manned spacecraft, such remote control tests the accuracy of operation and real-time judgment, and the process is quite boiling.
The moon landing also provides a reference proof of the authenticity of the Apollo 11 moon landing from the side. The most direct verification is the lunar soil brought back from the moon, which has been tested, except for the fact that there are more rare rare earth elements due to the difference in the collection site (Chang'e-1 is near the uncaught crater), there is not much difference in the composition of the lunar rock brought back by the United States Apollo 11.
Of course, if you calculate that there are similarities between the moon and some material on the earth, this may not be overturned.
<h1 class="pgc-h-arrow-right" data-track="20" > moon landing is not so simple</h1>
It may be because the Apollo 11 moon landing process is too smooth in many people's views, so it is difficult to easily believe its success, coupled with the Apollo series of moon landing programs, the United States did not launch another manned spacecraft to the moon, which is considered by many people to be a manifestation of weakness.
In fact, the United States has spent too much energy and money on this 11-year-long moon landing program, which involves more than 300,000 people. In the 1960s and 1970s, they had spent $25.5 billion on space technology, accounting for 20 percent of the nation's funding. It can be said that at that time, in order to gain an advantage in the US-Soviet hegemony, they had already consumed too much in the space race.
Obviously, the current United States may no longer be able to concentrate so many efficient talents who are willing to work hard, and if the country concentrates a huge amount of money on a research project, other research fields may not be so happy.
In any case, the success of the Apollo 11 moon landing is a great innovation in the history of spaceflight, which is of epoch-making significance. Whether it is the research process of the moon landing or the entire process of landing on the moon, it is not so simple, and the success of the Chang'e-5 and Apollo 11 moon landings shows the possibility of human technological development.
In fact, now there is no need to dwell on some things that have passed, after all, everything in the world is going forward, how far can it go, how stable the road is, and each depends on its ability, isn't it?
