Answer: It was 11:56:20 on July 21, 1969.
Q: Which astronaut from which country was the first to land on the moon?
Answer: Armstrong of the United States (Armstrong was the first to set foot on the moon)
Q: What are the theories about the origin of the moon?
Answer: Rock samples on the earth and the moon have been analyzed before, and they are said to be exactly the same and should originate from the same material. But there are many problems in thinking so hastily that the earth and the moon belong to the same family. For example, how the moon and the earth formed from the same material at the same time. There is a theory that the early Earth rotated so fast that it began to expand and eventually broke apart and separated the moon. Unfortunately, not many people are convinced by this statement.
According to "New Scientist", Swiss scientists also recently compared rock samples from the moon and the earth, but the conclusions were different from the above-mentioned research. They used a mass spectrometer to vaporize the sample through argon combustion, and analyzed the weight of the components in the sample with high precision. They found that although the two were very similar in most aspects, the ratio of iron 57 to iron 54 isotopes in the moon rock sample was higher than The ones on Earth are a little higher.
The researchers said: "The only thing we can explain is that during the formation process of the moon and the earth, they were partially vaporized." Only the "giant planet collision" theory can have the characteristics of vaporized atoms. A high temperature environment exceeding 1700 degrees Celsius is required. About 50 million years after the birth of the solar system, a planet the size of Mars (Theia) collided with the Earth. This catastrophic collision was so powerful that it may have been 100 million times greater than the energy released by the planetary collision that wiped out the dinosaurs. It was enough to melt and vaporize a considerable part of the earth. Theia was also completely destroyed. The debris from the collision entered Earth's orbit and eventually merged to form the Moon.
When iron atoms are vaporized, the lighter isotopes evaporate first. Since the remnant that became the moon has been completely vaporized, it may have lost more lighter iron isotopes, which means that the ratio of iron 57 to iron 54 on the moon is higher than that on the earth. The reason why scientists have the above explanation is based on this point.
There was another theory about the origin of the moon, which believed that passing celestial bodies were "grabbed" by the earth's gravity. The mystery of the origin of the moon has aroused the interest of many scientists. This year, the European Space Agency will use a satellite to launch a 3-kilogram, oven-sized compressed image display X-ray spectrometer. The instrument will orbit the moon along an elliptical orbit only 1 kilometer above the lunar surface, monitoring and recording different light wave data. Among them, the first complete high-resolution lunar map measured by it and the data on the ratio of magnesium and iron obtained will hopefully tell us where the moon originated.
Q: What resources can be utilized on the moon?
Answer: Soil, rock, hard metal, radioactive material, magnetic field, etc.
Q: What is the artificial moon?
Answer: Use a huge reflector to reflect sunlight to the backlit surface of the Earth
Question: How far is the moon from the Earth?
Answer: More than 380,000 kilometers
Q: Is the moon a sea? Why?
Answer: No, it is a plain. Because the dark and less characteristic lunar plain is called "lunar maria", this is because ancient astronomers believed that it was an ocean. In fact, the lunar maria were formed by basaltic magma that flowed out of the lunar mantle and covered the surface after the impact of a giant meteorite.
Q: What is the name of the largest lunar sea?
Answer: The largest sea is Oceanus Procellarum, with an area of ??about 5 million square kilometers
Q: Which is older, the moon or the earth?
Answer: The moon is big
Q: What is the radius of the moon?
Answer: 1738 kilometers
Q: Why does a solar eclipse occur?
Answer: Whenever the moon moves between the earth and the sun, and the three celestial bodies are aligned, a solar eclipse will occur. The moon blocks sunlight and creates shadows on the Earth, preventing some areas from receiving some or all of the sunlight. How much the Sun is obscured by the observer's view depends on where they are relative to the Moon's shadow. If observers are in the penumbra, they will see a partial eclipse, while those in the umbra will see a total eclipse.
Q: What are the big and small craters on the moon?
Answer: It was hit by a meteorite. Under normal circumstances (such as the Earth, there is an atmosphere on the periphery. When meteorites pass through the atmosphere, friction occurs with the air. This heat is enough to burn the meteorites. There are a few large ones or those containing some special substances that are not fully burned. fell to the ground)
There is no atmosphere around the moon, so meteorites fall directly to the surface of the moon, forming this kind of crater. Look at it, does it look like a stone falling to the water? .
Question: Why are people so light when they reach the moon?
Answer: Because the moon’s gravity is small
Q: Why does the moon wax and wane?
Answer: It is a natural phenomenon caused by the movement of the sun, earth and moon
Q: Can buildings on the earth be seen on the moon?
Answer: Neng (The Great Wall)
Question: Is the moon a planet?
Answer: No, it is a satellite of the Earth

The Story of the Moon: Chang'e's Flight to the Moon
According to legend, one year in ancient times, ten suns appeared in the sky, which were so scorching that the earth smoked and the sea water Withered, the people saw that they could no longer live.
This incident alarmed a hero named Hou Yi. He climbed to the top of the Kunlun Mountains, used his supernatural power, drew his magic bow, and shot down nine superfluous suns in one go.
Hou Yi made unparalleled achievements and was respected and loved by the people. Many people with lofty ideals came to study under him. The treacherous and evil-minded Peng Meng also sneaked in.
Soon, Hou Yi married a beautiful and kind-hearted wife named Chang'e. In addition to spreading his skills and hunting, Hou Yi stayed with his wife all day long. People envied this loving couple with talent and beauty.
One day, Hou Yi went to Kunlun Mountain to visit friends and seek enlightenment. He happened to meet the Queen Mother who was passing by, and asked the Queen Mother for a package of elixir. It is said that if you take this medicine, you can immediately ascend to heaven and become an immortal.
However, Hou Yi was reluctant to leave his wife, so he had to temporarily give the elixir to Chang'e for collection. Chang'e hid the medicine in the treasure box on the dressing table, but Pengmeng saw it.
Three days later, Hou Yi led his disciples out for hunting. Peng Meng, who had evil intentions, pretended to be sick and stayed.
Soon after Hou Yi led everyone away, Peng Meng broke into the backyard of the inner house with a sword and forced Chang'e to hand over the elixir.
Chang'e knew that she was no match for Peng Meng. In the critical moment, she made a prompt decision, turned around, opened the treasure box, took out the elixir and swallowed it in one gulp.
Chang'e swallowed the medicine, and her body immediately floated off the ground, rushed out of the window, and flew to the sky. Because Chang'e cared about her husband, she flew to the moon closest to the world and became an immortal.
In the evening, Hou Yi returned home, and the maids cried about what happened during the day. Hou Yi was frightened and angry. He drew his sword and went to kill the villain, but Peng Meng had already escaped. Hou Yi was so angry that he beat his chest and stamped his feet, screaming. The grief-stricken Hou Yi looked up at the night sky and called his beloved wife's name. At this time, he was surprised to find that today's moon was particularly bright and bright, and there was a swaying figure that looked like Chang'e.
Hou Yi hurriedly sent people to Chang'e's favorite back garden, set up an incense table, placed her favorite sweetmeats and fresh fruits, and offered sacrifices to Chang'e who was attached to him in the moon palace.
After the people heard the news that Chang'e flew to the moon and became an immortal, they set up incense tables under the moon and prayed to the kind-hearted Chang'e for good luck and peace. From then on, the custom of worshiping the moon during the Mid-Autumn Festival spread among the people. The story of Chang'e flying to the moon praises and praises Chang'e with a distinctive attitude and brilliant colors. Compared with the records about Chang'e in ancient documents, it can be seen that people have done a lot of processing and modification to the story of Chang'e flying to the moon, making the image of Chang'e It is as beautiful as the moon, making it in line with people's pursuit of beauty. Contrary to the widely circulated modern "Chang'e flying to the moon", "Lingxian" compiled by "Quan Shang Gu Wen" records the story of "Chang'e turning into a toad": "Chang'e, Yi's wife, stole the Queen Mother's immortal medicine and took it, and flew to the moon. The moon is about to pass, and Huang Zhanzhi says: "Ji, Pianpian returns to her sister, and will go west alone. Don't be frightened when the sky is dark, and she will be prosperous later." "Toad." After Chang'e turned into a toad, she was punished to pound the elixir all day long in the moon palace, and lived a lonely and miserable life. Li Shangyin once lamented Chang'e in a poem: "Chang'e should regret stealing the elixir, and the blue sea and blue sky make her heart full every night." p>
