The Apollo mission to the moon has sparked heated discussions, why should the lunar module and lunar

A document entitled "Catalogue of Man-Made Objects on the Moon" was explained, listing each of the individual items that had been left behind.

In the past half-century, humans have visited the moon many times, and these expeditions have been both challenging and profound.

As the Moon becomes more accessible to national space and private businesses, the preservation of human heritage on the Moon will become increasingly important for historical and scientific reasons.

Based on currently available data, the resource provides a record of man-made objects on the Moon. ”

Among the items listed are the Golden Olive Branch, the Apollo 1 fragments, the Moon Medal and the Astronaut Medal, which are all memorabilia commemorating the event.

However, there are also some strange everyday items: a television subsystem (a small system that has some kind of function and is independent), the moon, a camera, a lunar TV, a TV wide angle, a cable assembly, a TV (100 inches), an antenna, an S-wave (transmitting device) and a package, a lunar transfer device.

Surprisingly, it was recently discovered that Armstrong had made a mistake in saying a few words before Apollo 11.

People on Earth hear: "This is a small step for humanity, a giant leap for humanity." ”

Because these things have no value. There is no need to take it back.

Because these things are useless and not worth bringing back.

Because they can't have too much weight when they have to return to Earth

Because it is difficult to bring back the lunar module and the lunar landing equipment.

It may be that it was difficult at that time.

Tell someone he's been here.

It may not be easy to bring back, and it can also serve as a marker.

said that he had been here and could find the same place next time.

These things are useless.

You can't return to Earth with too much weight.

The success of the "Apollo" moon landing program enabled mankind to leave the earth for the first time and reach other celestial bodies, which was a milestone for mankind to enter space to open up new frontiers, and also created conditions for mankind to develop and use the moon in the future.

American manned lunar landing program - Apollo program.

First of all, the background of the launch of this program should be known, it is nothing more than the competition of strength between the "United States and the Soviet Union" in those years, and we will not explain much here, since 1961, the United States launched this program, and after about 11 years, finally completed the process of manned lunar landing, and realized manned lunar flights and human field expeditions to the moon. Indeed, although it took about 11 years for the United States to implement this plan, it was really successful.

Of course, this success was not an easy task, and it also sacrificed three astronauts, during the implementation of the Apollo 1 program, astronauts Virgil Gleason, Edward White, and Roger Chaffee died, and the first American astronaut to successfully land on the moon was named "Neil Armstrong", which was implemented in the Apollo 11 program. He walked on the lunar surface for two and a half hours.

So the time is relatively long, of course, this spacewalk, is the "first step" of human beings to the moon, after the Apollo spacecraft program has been carried out many times, of course, the American Apollo program brought back about 400 kilograms of samples from the moon, which can be regarded as a great contribution to mankind, at that time the United States also shared the rock results of the moon with our country, and also proved that it was from the moon, so the American manned lunar landing program - the Apollo program is real.

So why not manned the moon now, there is really an ulterior secret?

In fact, there are really no ulterior secrets on the moon, and since the implementation of the Chang'e project in China, everyone has also seen that the basic situation of the moon is similar to that of the United States, and there are no ulterior secrets. Then why is there no manned landing on the moon now, the main thing is a technical problem, a cost problem. Strictly speaking, the United States does have the technology to land people on the moon, and other countries may continue to study it and are about to implement it.

Technology is one thing, and the other is the cost problem, you may be unbelievable, the United States to achieve the manned moon landing of the Apollo program, is a huge amount of money, the Apollo program began in May 1961, to December 1972 the sixth moon landing successfully ended, lasted about 11 years, cost 25.5 billion US dollars, this funding accounted for about the United States GDP that year, about 20% of the United States science and technology research and development funds that year. At the peak of the project, 20,000 enterprises, more than 200 universities and more than 80 scientific research institutions participated in the project, with a total number of more than 300,000 people.

It is conceivable that the United States has spent "blood" in order to realize its own technology, so it is really not easy, although this is a "historic" leap, but it does cost too much money, and the "space impression" brought to mankind is also very profound. So with such a huge amount of money, with the participation of so many people, few countries are willing to do this again, which may be part of the reason.

Therefore, on the whole, technology, funding and other issues may have slowed down the pace of human landing, that is, there has been no manned landing on the moon again for decades. But now, with the development of human beings.

After the successful landing of the Apollo program on the moon, helium-3, the most useful resource for human beings on the moon, will become the most ideal raw material for human controllable nuclear fusion.

The Apollo moon landing opened a new era in the history of human aviation, landed on the moon for the first time, collected many samples, let human beings better understand the structure of the moon and some basic conditions, and provided conditions for human beings to understand the universe and even immigrate to other planets in the future.

The Apollo program is one of the most important achievements in the history of human spaceflight, as well as the equipment it left on the moon, as well as the lunar soil (or rocks) that brought the Earth to this day, still help us understand the Moon. From the samples brought back from the moon, it is easy to determine the age of the moon and its surface, and these data suggest that the moon should have formed early in the solar system.

During the Apollo moon landing, no rover remained on the moon, because each vehicle had an automatic return home setting. There is currently no lunar rover left on the moon.

Only four lunar rovers were built in the Apollo lunar landing program, one of which was not used, and the remaining three lunar rovers were all left on the moon. It is also believed that the Apollo moon landing program is real based on whether there are any traces of a lunar rover on the moon.

There was no lunar rover left on the moon during the Apollo moon landing, and after using the lunar rover to mine lunar samples, it was loaded with a return rocket and returned to Earth, and the lunar rover was equipped with a return system.

There is no lunar rover left on the moon in the pineapple lunar landing program, because it will eventually return to Earth in the lunar rover, which is a set return system. And staying on the moon will end up as space junk.

One of the lunar rovers in the Apollo moon landing was completely left on the moon, which was the first lunar rover to land on the moon, because the technology at that time did not reach the stage of the lunar rover's return, so it could only choose to abandon it.

Stay on a Hollywood studio!

Knowing that it was cheating, it was still pushing.

Not on the moon, it's all in Hollywood, and the United States doesn't waste it.

The instrument that set up the book and was more than 70 kilometers away from the fall site of Yuzi Heng also recorded a ** sound that lasted for 15 minutes. This radio ** sound is like the sound of a huge bell, which spreads farther and farther and weaker. Scientists analyze the situation and believe that the moon may be hollow, because if the moon is solid, this sound will only last for 1 minute.

As early as 1961, John F. Kennedy announced to the world that "the United States will send an American to the moon within ten years, and will bring him back to earth." Since then, the United States' ambitious "Apollo Rubber Landing Plan" has been implemented.
