In recent days, a piece of news has been frequently swiped on major social media platforms. This is the news of China’s Chang'e 5 returning from the moon. The successful return of Chang'e 5 is a highlight in China's aerospace history, and it has made countless Chinese people proud. Speaking of which, China’s aerospace industry has actually been moving forward in great strides. China is exploring space and everything around the earth at an unprecedented speed. According to China's aerospace plan, China will eventually send astronauts to the moon and successfully land on the moon to achieve walking on the lunar surface.
China’s aerospace industry is constantly developing, but only by comparison can we know where our development has reached. China's Chang'e 5 brought back the lunar soil from the moon, but in the last century, the Americans brought back the full 382kg soil from the moon. How does do this?
1. Spending huge sums of money on space exploration
The American Apollo project is a plan for lunar exploration. In this plan, Americans have flown 17 times between the earth and the moon, and a total of 17 times on the surface It landed 6 times and brought back 382 kilograms of soil and rock samples from the moon.
The Americans implemented this plan more than 50 years ago, that is to say, the Americans have achieved China's current achievements with the technology 50 years ago. Although there are some disappointments, this is one thing that must be mentioned. China still has a long way to go before becoming a major aerospace power. The Apollo spacecraft used to implement the Apollo program is much larger than the Chang'e 5 currently launched by China. The total weight of Chang'e 5 is about 8.2 tons, and the total weight of the Apollo spacecraft is 50 tons. It can also be seen from here that the technology at the time was indeed very backward, so that such a huge weight was needed to realize the round trip between the earth and the moon.
A 50-ton behemoth, it is conceivable that in order to launch it into the sky, it will inevitably require a lot of fuel. In fact, the Apollo spacecraft relies on the Saturn 5 carrier rocket to fly into space. The Apollo spacecraft itself is about 25 meters high. When it is connected to the Saturn 5 carrier rocket, the entire height reaches 110 meters. The thrust of the Saturn 5 carrier rocket is very powerful. The Saturn 5 uses a total of 5 Fz8
9z engines, and the sea level thrust of a single engine exceeds 700 tons. It is this behemoth that enables the Americans to transport astronauts and astronauts. All the supplies needed for the life of the members were sent to the moon.The reason why the Americans implemented such a plan is actually inseparable from the Soviets. The Soviets launched an artificial earth satellite into space for the first time, and also the first country to send their own astronauts into outer space. Under such stimulus, the Americans launched the Apollo project, hoping to firmly control the commanding heights of space exploration in their own hands.
According to existing data, the cost of the Apollo program in the United States has reached 25 billion US dollars. But many people questioned the cost of this plan. These people think that $25 billion is simply not enough to achieve such a large achievement. Americans are likely to have moved on the budget.
According to speculation, the implementation of all the projects of the Apollo program cost about 100 billion US dollars. The reason why the United States claims that it has only $25 billion is actually to paralyze its opponent the Soviet Union. The Americans wanted to pull the Soviet Union into the invincible abyss of the space race. In order to fool the Soviets, they had to lower this budget. Otherwise, seeing so much expenditure, the Soviets would most likely immediately give up space exploration. Why can Americans spend so much money on space exploration?
2. Economic strength determines the status of a country
Don’t think that all the money is provided by the US government. If you really want to take it seriously, everyone in the world has contributed to American space exploration. It’s just that this contribution happened unknowingly, the cunning AmericanThe mystery of this was not disclosed to the public.
After the Second World War, the entire world was almost in ruins. The Americans took advantage of the trend and established the Bretton Woods system. Everyone knows that Americans have financial hegemony, but they don't know how this hegemony was established.
According to the provisions of the Bretton Woods system, the currencies of all countries in the world are linked to the US dollar, and the US dollar is linked to gold. It is this rule that allowed the U.S. dollar to grasp financial hegemony and pave the way for the United States to become a technological power. When
played a role in the Bretton Woods system, all trade in the world was finally converted into US dollars for settlement, and Americans made a lot of money in this. Don't forget that the US dollar is just a piece of paper in the final analysis. Even if the US dollar is linked to gold, it is up to the Americans to decide how many US dollars can be issued. Z9z
currency issuance has its own certain rules, and Americans obviously did not follow such rules. They issued unlimited currency and exchanged depreciated U.S. dollars for products produced in other countries. This is why Americans can spend a full $100 billion on the Apollo project, because they are not short of money at all. All money is actually just numbers.
Moreover, spending such a large sum of money on the Apollo project can be deceptive. If Americans print money openly, and use excessive US dollars to arbitrage the wealth of the people of other countries, it will inevitably arouse criticism from other countries. Issuing currency in the United States will definitely not be criticized by other countries. No matter what, Americans can use the money or stay in the United States. The reason for the impact on the world economy will not cover the past.
These investments have made American scientific research institutions a lot of money. The money continues to operate in the United States, becoming new investment and new consumption, which greatly promotes the further development of the economy. For Americans, is equivalent to a sum of money but did three things. It not only pulled the Soviets down, but also stimulated their own economy, and at the same time completed space exploration.
The Soviet Union at the same time as the United States was not so lucky. Due to limited funds, although the Soviets spent a lot of money on space exploration, the results were not as good as the Americans. With the disintegration of the Soviet Union, the achievements of the Soviet Union were reduced to ashes and became the laughing stock of the Americans. Z1z
has said so much, what is the situation in China? The Chang'e 1 cost the country 1.4 billion yuan, and the Chang'e 5 cost China 3 billion yuan. The sum of all this money is not enough to make up a fraction of the 25 billion Americans spent that year.
China has accomplished the same thing with less money and higher technology. From this perspective, China's aerospace technology is indeed capable of breaking the wrist with the Americans.
But this also shows the difficulties of China in space exploration from the side. Americans can swindle money from people all over the world by printing money, while the Chinese can only tighten their belts and save money to complete space exploration. Which is better or worse, you can tell at a glance. The
Chang'e 5 only flew once. Compared with the planned and purposeful flights of the Americans, the Chinese are actually making more attempts. Chang'e 5 can already achieve such a goal . If it wants to bring back soil from the moon, China can definitely bring back more soil, but it doesn't need it.
Summary
From Chang'e 5, people should not only see China's achievements in space exploration over the years, but also see its own shortcomings. Americans have already walked on the moon in the last century, while China is still making constant exploration.
This is actually a helplessness for developing countries. Capitalist countries can rely on their huge wealth and economic hegemony to reap the wealth of the world. Developing countries can only move forward cautiously step by step without tolerance for mistakes. China's achievements need to be guarded by all citizens, and all Chinese people can unite as one to make China's space industry go further. The picture of
