Why hasn t humans landed on the moon again in the last 40 years?

The United States does have the strength to go to the moon again, and it can be done at any time, but it is difficult to say whether it will be easy or not.

It's like my country can open a few more 4 trillion yuan at any time to celebrate with the whole world, but no one dares to do it.

First of all, the scientific community does not agree with the value of human moon landing, and the ability to go to the moon was a pursuit of political effects, while the scientific community believes that spending money on unmanned space is low cost and low pressure, and human moon landing is meaningless. And the next step in landing on the moon is to land on Mars, and developing the moon as a space base is of no value for landing on Mars, but it has some significance for future space migration, which is too far.

Secondly, now that there are no visible benefits to the moon landing, Americans are very good at it, and what can they do with spending hundreds of billions repeating the achievements of the Kennedy era? It's still early to develop helium-3. Landing on Mars is about the same, then the cost will be great.

However, I think that if China lands on the moon, the Americans' Mars program will definitely accelerate.

Third, the failure of the space shuttle project can be said to be the main reason for the decline of the US space industry today, because the technology is too advanced, resulting in extremely low reliability, no commercial value at all, and it is doomed to have no future in the capitalist world where it cannot be commercialized. Numerous promising launch vehicle projects made way for it, with the result that they are now inavailable.

Of course, if the general environment remains the same, then a few failures are not a big problem, in the 50s the failure of the United States aerospace was like a joke did not affect the work much, the tragedy is to catch up with the end of the Cold War, the space shuttle by the Air Force half of the money, and after the end of the Cold War, the United States defense projects suffered major failures one after another (only the Air Force F22 fruit remained, artillery, ***, attack aircraft were all cut), the Air Force's enthusiasm for spending money quickly decreased, and the next generation of space shuttles was completely unmanned. Therefore, NASA had no choice but to take the pro-people route and instead support private aerospace companies, first cultivating the market and then talking about technological progress. The living environment of private enterprises is so pitiful, but the country has always been clamoring for private capital to enter various fields, in fact, it doesn't want to spend money.

In short, no one agrees that it is meaningless to waste so much money, and there is no need to repeat the demonstration of Mohashiqing's national strength.

In other countries, in short, no one agrees to waste so much money, there is no point in holding it, there is no need to show national strength in this way, or there is no technology, there may be technology, but it does not dare.

The Awa delegation spent a total of $5 billion on the moon landing, and now it is estimated that there are 200 billion dollars, which can build 40 aircraft carriers. What's more, now that the US economy is not in good shape, it has spent money year after year, and there is no longer a threat from the Soviet Union, so it has given up.

Because it's not fun at all on the moon, it's either freezing to death or dying of heat, and there's no scenery.

For mankind with infinite intelligence, the realization of a manned landing on the moon is no longer a technical problem. After all, in the last century, before the development of science and technology, we have successfully launched humans to the surface of the moon. The reason why countries no longer conduct manned lunar landings is actually due to cost considerations.

We know that spaceships need to be launched with rockets. A manned landing on the moon not only places high demands on the spacecraft, but also increases the weight of the spacecraft. The heavier the spacecraft, the higher the cost of launch.

Launching a spacecraft to the moon is a kind of deep space exploration, which has higher requirements for rockets, and the corresponding launch cost will increase a lot. The United States, the only country that achieved a manned landing on the moon, did not go to the moon again, and it was more difficult for other countries to go to the moon. After all, the United States has never shared the technology to successfully land on the moon in the first place.

If other countries want to go to the moon, they have to start working again. In addition, only the United States and Russia have the technology to create rockets for the needs of a manned landing on the moon. Therefore, it is indeed difficult for other countries to achieve a manned landing on the moon with their own strength and efforts.

There are certain dangers associated with a manned landing on the moon. Although science and technology have made great progress compared to the Apollo manned moon landing, there is still the possibility of a failed manned moon landing. Therefore, although countries are ready for a manned landing on the moon, they have not yet achieved a manned landing on the moon.

However, China has already proposed to carry out a manned landing on the moon in the future and create a base on the moon.

The surface of the Moon is not as active as that of the Earth. Due to the lack of atmosphere, water, and a global magnetic field, it is difficult for life to be born on the surface of the moon. In addition, the atmosphere on the surface of the Moon is thin and free of clouds, rain, wind, and frost, so the traces left by astronauts on the Earth's surface will remain on the surface of the Moon for a long time.

In the future, there will be an opportunity to travel to the moon, and perhaps we can find these traces again. More than 40 years later, this does not mean that humans do not have the power to land on the moon. On the contrary, various factors led to the belief that the moon landing was not only unnecessary, but also of little significance, especially for the United States.

Because there is no need to go to the moon again, the resources wasted by the moon landing are relatively large, and there is nothing special on the moon, which is not caused by insufficient technology.

Because it is very difficult to go to the moon, humans have not landed on the moon again, and I think it is because of the lack of technology.

Because some countries are not capable enough, they cannot go to the moon again. There is a reason for this, and there is also a reason because there is no time.

Because human beings have a very good understanding of the moon, they did not go to the moon. It's not because of the lack of technology.

Summary. The reason is very simple: because people are no longer satisfied with just digging stones and planting a flag - not to mention, this simple operation, the robot is not only more suitable, but also cheaper - abandoning the complex "human" factor, the launch tonnage can be greatly reduced, and the natural cost is also greatly reduced.

Humans have had many fantasies about the moon, but flying to the moon to see it has been regarded as a dream for thousands of years, until the implementation of the American Asan Polo program. After a series of preliminary tests and preparations, on July 21, 1969, the American "Apollo 11" spacecraft successfully landed on the moon with three astronauts, and the first human to set foot on the moon was the American astronaut Zenzheng Armstrong. The Americans were the first to turn the dream of a human being on the moon into reality.

Why is it that humans have not landed on the moon again? China and the United States tacitly understand that the reason is very simple2020-01-24 07:37·Tiger said that human beings had many fantasies about the moon, but for flying to the moon to see it, it was regarded as a fool's dream for thousands of years, until the implementation of the American Apollo program.

After a series of preliminary tests and preparations, on July 21, 1969, the American "Apollo 11" spacecraft successfully landed on the moon with three astronauts, and the first human to set foot on the moon was American astronaut Armstrong. The Americans were the first to turn the dream of a human being on the moon into reality. The strange thing is that after the end of the Apollo program, the United States seemed to have forgotten about the moon landing and did not regret that it was interested in further research on the moon.

This has made many people suspicious, suspecting that the Apollo moon landing was a fraud, and that the astronauts on the moon were actually filmed in Hollywood. Why else did the Americans never go to the moon again? Conspiracy theorists have also put forward a lot of evidence, mostly in reference to some of the moon landings filmed at the time.

In response to this controversy, NASA has specifically refuted the rumors, but there are still people who suspect that the United States has faked the moon landing. In fact, the best way to prove that the Apollo program is real is to go to the moon one more time, so that everyone will shut up. But so far, the United States has not proposed a definite plan to go to the moon, only vaguely saying that it will return to the moon.

Mankind has successfully carried out many missions to the moon from the 60s to the 70s of the 20th century, but due to various reasons, such as budget constraints, technological constraints, etc., there has been no human landing on the moon since 1972. Although NASA has proposed a number of plans for a new moon landing in the resale type, these plans have not received sufficient budget and support, so they have not yet been realized. In addition, the risk of a human mission to the moon is high, which can make ** and private companies hesitate.

Hello dear, why humans are no longer on the moon is an interesting question. There are several main reasons: Economic reasons:

Landing on the moon is a very expensive project that requires a lot of investment, manpower, and material resources. At that time, the United States launched the moon landing program, mainly to surpass the Soviet Union in the space race and demonstrate its scientific and technological strength and political will. But after the successful landing of Apollo 11 on the moon in 1969, the United States reached this goal, and the subsequent mission to the moon was less urgent and necessary.

Moreover, the United States was facing multiple challenges such as the Vietnam War, urban problems, and environmental crises, and public support for continuing to invest huge sums of money in the moon landing program declined. Thus, in 1970, the United States canceled the future Apollo mission, and Apollo 17 became the last manned mission to the moon. Political reasons:

The moon landing program is not only a project of scientific exploration, but also a politically declared action. During the Cold War, the United States and the Soviet Union competed fiercely in the field of space, trying to prove their superiority and influence. However, in the late 1970s, the situation eased somewhat, and the United States and the Soviet Union began to engage in some cooperation and dialogue, such as the Apollo-Alliance Experimental Program (ASTP) in 1975, the first joint mission between the two countries in space.

In this way, the moon landing program has lost its original political significance and urgency, and has lost its strong impetus. Scientific reasons: Although the moon landing program has brought a lot of new scientific knowledge and technological achievements to mankind, it also has some limitations and risks.

First of all, the lunar landing program can only explore a small area of the lunar surface, and cannot have an in-depth understanding of the internal structure and evolution process of the moon. Secondly, the lunar landing program needs to face many technical difficulties and safety risks, such as possible failures, accidents or collisions during rocket launch, landing, and return. Thirdly, the moon landing program also has a certain impact on human health, such as long-term exposure to microgravity, radiation, dust and other environments may lead to bone loss, muscle atrophy, and a weakened immune system.

Therefore, it is also a prudent and rational choice for humans not to go to the moon until there is more advanced technology and a more adequate reason.
