The moon hangs high in the night sky. In the eyes of Newton, it has been with the earth for more than four billion years. In fact, it is the same as the apple that ripens and falls. The force that causes this result is the same kind of force - universal gravity. The moon is a planet that is both familiar and unfamiliar to humans. From our perspective, as the only natural celestial body on the earth, the moon is both familiar and unfamiliar.
Human beings have had the desire to fly to the moon since ancient times, and this wish was realized during the space hegemony between the United States and the Soviet Union in the last century. Not to mention how deformed the original purpose of their space competition was. The United States and the Soviet Union just wanted to overwhelm each other. For this reason, both countries have proposed plans to launch nuclear bombs on the moon. The purpose is to release a large firework on the moon to demonstrate their national power, military and other factors.
Fortunately, the plan to blow up the moon was not implemented in the end. If the moon was really blown up, life on earth would probably come to an end. It looks like an ordinary moon, but its existence is crucial to the earth.
The moon is the closest natural celestial body to us. In the early days of human space exploration, the moon was the main detection target. For example, the United States and the Soviet Union tried their best to achieve manned landing on the moon, but in the end we all know that the United States achieved manned landing on the moon. In August, a total of 12 astronauts landed on the lunar surface, but the Soviet Union failed to achieve this goal by all means. In this contest, the Soviet Union was at a disadvantage.
In July 1969, the Apollo 11 manned spacecraft officially carried out the manned mission to the moon. Armstrong was the first to jump out of the lunar module , leaving the first footprints on the moon. This was the first time that humans as a species set foot outside the earth. Celestial bodies, from Apollo 12 to Apollo 17 , all missions were completed by 1972, except for the failure of and Apollo 13 that malfunctioned in the middle.
Apollo manned moon landing The capital investment and preparation time of the entire project can be said to be huge, but the real manned moon landing was concentrated in the years from 1969 to 1972.
As time goes by, more than half a century has passed since the first manned landing on the moon. Although the United States has a new plan to "return to the moon for technical verification and then manned landing on Mars", the current progress is It is slow and needs to solve a series of technical difficulties.
Starting from this point, we may feel a little surprised. The United States was able to carry out manned lunar landings in the 1960s. In just a few years, it carried out 6 successful manned lunar landings and sent 12 astronauts to the moon. To the moon. However, after more than half a century, the United States has not implemented its plan to return to the moon. What did American astronauts see on the moon?
The picture shows the scene of Apollo 11 astronaut Aldrin stepping off the lunar module. Armstrong, who set foot on the moon one step ahead of schedule, captured this scene. What did American astronauts see on the moon? It makes people wonder. Is it because of technical reasons that the United States no longer lands on the moon after half a century? Or just afraid to go to the moon again?
The moon is both familiar and unfamiliar to human beings. It is familiar because it has been with the earth for more than four billion years. We can see its existence just by looking up at the night sky, but the strange thing is that it is not the earth.
When astronauts land on the moon, the first thing they notice may be their "home". The earth looks even bigger and brighter in the night sky of the moon. Since the moon is tidally locked by the earth, only one side faces it. Earth, this means that from the moon we can look at the earth for a long time, as if it is hanging there motionless.
When astronauts land on the moon, the moment when they look back at the earth is the most terrifying, because it will make the astronauts feel a deep sense of loneliness and homesickness.
This has been mentioned in many conspiracy theory articles. During the mission, Apollo 11 lost contact for two minutes. During this lost state, Armstrong and Aldrin may have witnessed an unidentified flight. Objects, things they cannot understand appear at the edge of their vision at a position visible to the naked eye.
The moon is tidally locked by the earth, causing only one side to face the earth. On the back side of the moon is a world unfamiliar to humans. In the last century, the Soviet Union's Lunar 3 captured the scene on the back side of the moon. It was the first time that humans saw the back side of the moon. What does it look like.
Many people have always believed that the back side of the moon is the base of alien civilization. All UFO events that occur on the earth come from the back side of the moon. However, since humans have learned more and more, they have discovered that the back side of the moon only accepts celestial bodies. Impacts are more frequent, so the impact craters are denser, and the rest are not much different from the front of the moon.
After the United States achieved six manned moon landings in the last century, the reason why it stopped landing on the moon after more than half a century is actually not that complicated. No matter how delicious the food is, we will always get tired of it. that day. The manned moon landing is like this. It consumes a lot of manpower and material resources. If there is no necessary reason, manned moon landing will naturally not be carried out.
Secondly, manned lunar landings were the product of abnormal competition during the Cold War, and the safety requirements were not as high as they are now. Some people called the six manned lunar landings in the United States in the last century "done in a daze, and then again in a daze." "Back in the Past", a total of more than 380 kilograms of samples were brought back, and the rest was very little. At that time, the United States cared more about flowers and applause.
There is another very important reason, that is, the retirement of the Saturn V high-thrust launch vehicle, which has made manned moon landings elusive. This is why the United States has stopped carrying out manned moon landings after more than half a century. , the reason is very simple, maybe it’s not that you don’t want to, but that you can’t, and it has nothing to do with what the astronauts saw on the moon.
