I. Overview
moon
The moon is also called "the moon". Before the invention of the telescope, ancient people could only look up at the bright moon with their eyes on clear nights. Seeing the moon's surface flickering and strange in shape, people made up beautiful myths such as the Goddess Chang'e flying to the moon, Wu Gang's felling of Guangxi, Yu Mian's tinkering with medicine and so on. The ancient Greeks regarded the moon as the beautiful hunting goddess themis, and regarded the silver bow that the goddess never left when hunting as the astronomical symbol of the moon.
There is basically no water on the moon, so there is no weathering, oxidation and water corrosion on the earth, and there is no sound transmission. There is a silent world everywhere. The moon itself does not shine, the sky is always dark, and the sun and stars can appear at the same time.
There is almost no atmosphere on the moon, so there is a great temperature difference between day and night on the moon. During the day, where the sun shines vertically, the temperature is as high as127℃; The temperature at night can be as low as-183℃. Because there is no atmospheric barrier, the intensity of sunlight on the surface of the moon is stronger than that on the earth 1/3 or so. The intensity of ultraviolet rays is also much stronger than the surface of the earth. Due to the lack of atmosphere on the moon, many strange phenomena will be seen on the moon, such as the dark sky on the moon, direct sunlight and brilliant sunshine; It's dark where you can't shine. Therefore, we can see that the surface of the moon is bright and dark. As there is no air to scatter light, the stars on the moon no longer seem to twinkle.
The moon is full of rocks and craters. The whole surface of the moon is covered with gravel and residual soil. The surface of the moon seen from the earth has bright areas and dark gray parts. The original bright part is the mountains and highlands on the surface of the moon, and the dark gray part is the plain on the surface of the moon.
The moon is smaller than the earth, with a diameter of 3476 kilometers, which is about 3/ 1 1. The surface area of the moon is about114 of the surface area of the earth, slightly smaller than that of Asia. Its volume is 1/49 of the earth, in other words, the earth has 49 satellites. The mass of the moon is1/81of the earth; The average density of matter is 3.34 grams per cubic centimeter, which is only 3/5 of the density of the earth. The gravity on the moon is only 1/6 of that of the earth, that is to say, something weighing 6 kilograms will only weigh 1 kg on the moon. When people walk on the moon, their bodies look relaxed and they can jump up with a little effort. Astronauts think that walking on the moon seems more enjoyable than walking on the earth.
The moon is the closest celestial body to the earth. It is the only natural satellite orbiting the earth, with an average distance of about 384,400 kilometers. The moon's orbit around the earth is circular, with an average distance of 363,300 kilometers at perigee (when it is closest to the earth) and 405,500 kilometers at apogee (when it is farthest from the earth), with a difference of 42,200 kilometers.
The moon, like the earth, is a flat sphere with slightly flat north and south poles and slightly higher equator. Its average polar radius is 500 meters shorter than the equatorial radius, and the north and south poles are also asymmetrical. The North Pole rises and the South Pole sinks about 400 meters.
When the moon goes around the earth, it also goes around the sun with the earth. That is to say, after the moon orbits the earth once, the space position it returns to is not the original starting point. It can be seen that the moon should participate in the movement of various systems in the process of movement. Like other celestial bodies, the moon is always in motion. The moon moves from west to east by more than 13 degrees on average every day, so the moon rises about 50 minutes later than the previous day. The rise and fall of the moon is a reflection of the earth's rotation; The movement from west to east is the result of the moon's revolution around the earth. One revolution of the moon around the earth is called "sidereal moon", with an average of 27 days, 7 hours and 43 minutes 1 1 sec. When the moon revolves around the earth, it also rotates. The moon's rotation period is equal to period of revolution, that is, 1: 1, and the time for the moon to go around the earth is the rotation period.
As a result of this strange rotation of the moon, the moon always faces the earth with the same half, and what the back of the moon looks like can never be seen from the earth. Only through the detector can we solve the mystery on the back of the moon. This wish of mankind was realized as early as 30 years ago. Today's large astronomical telescopes can distinguish targets about 50 meters (equivalent to 14-story buildings) on the moon.

The moon has many interesting reputations in China's ancient poems: jade exemption (deliberately climbing stairs to find jade exemption, who covers the silver que with a curtain-Xin Qiji); Luminous (luminous, why do you have children when you die? —— Qu Yuan); Su E (Su E is another name for the moon-Youxue Qionglin); Ice wheel (the jade hook decides who to hang, but the ice wheel is helpless-land tour); Jade wheel (jade wheel meets wet light, Luan Pei meets a stranger in Gui Xiang-Li He); Jade toad (cold night fog outside, three or five jade toad autumn-Fang Gan); Gui' ao (Gui' ao flies to a sunny place and enjoys a cool day in autumn-Su Shi); Toad (Fujian set sail, but toad lost his reunion-Jia Dao); Ancient pictures (Yang birds don't come out of the valley, and ancient pictures are half hidden-Li Bai); Chan Juan (I wish people a long time, and we are thousands of miles together-Su Shi). In addition, there are many unique nicknames on the moon, such as Jade Bow, Jade Gui, Jade Plate, Jade Hook, Jade Mirror, Ice Mirror, Guanghan Palace, Chang 'e and Jade Sheep.

About the mystery of the moon
The moon is that clos celestial body to the earth, with a distance of 384,000 kilometers. Astronomers have made detailed observations on the moon with telescopes, and they know the terrain of the moon like the back of their hands. There are mountains and plains on the moon, and there are countless deep pits and gullies, but there is no water and air. The temperature difference between day and night is hanging, lifeless and desolate. Although the giant telescope can distinguish the target about 50 meters on the moon, it is still not as clear as the field trip. Therefore, the moon is still the first extraterrestrial object visited by human beings.
The United States launched the lunar probe for the first time in August 1958, but it died halfway because of the explosion of the first stage rocket. Subsequently, three Pioneer probes were launched one after another, all of which ended in failure. 1 959 65438+1On October 2nd, the former Soviet Union launched the lunar probe1,and it flew smoothly on the way. It passed 7500 kilometers from the surface of the moon in 654381October 4, but unfortunately failed to hit the moon. This detector weighs 36 1.3kg and is equipped with the most advanced communication and detection equipment at that time. Nine months later, it became the first man-made planet to fly deep into space. On March 3, two months after the launch of Lunar/KLOC-0, Pioneer 4 launched by the United States flew over 59,000 kilometers from the surface of the moon without hitting the moon.
Lunar probe
From 1958 to 1976, the former Soviet Union launched 24 lunar probes, of which 18 completed the lunar exploration mission. 1September, 959 12, Chang 'e II flew to the moon two days later and made a hard landing on the surface of the moon, becoming the first messenger to reach the moon and realizing the flight from the earth to another celestial body for the first time. The radio communication device in its scientific instrument cabin stopped working after hitting the moon. In the same year, Lunar 3 flew to the moon on June 4, 65438, and circled the moon three days later, taking the first picture of the back of the moon, which made people see the whole picture of the moon for the first time. The first lunar soft landing probe in the world was Lunar 9, and the launch time was June19665438+1October 3 1. After a long flight of 79 hours, it landed near the stormy ocean of the moon and took pictures of the moon with a camera. This detector weighs 65,438+0,583 kilograms. When it reaches 75km away from the lunar surface, the lander with a weight of1000kg is separated from the probe body and landed slowly by an automatic inflatable balloon installed outside. The moon 16, which was launched on September 2, 1970/kloc-0, made a soft landing on the rich lunar sea on September 20. For the first time, a sample of120g moon rock was collected with a drill bit, put into a sealed container of the recovery cabin, and brought back to Earth on 24th. 1970165438+1October 10, and the moon 17 carried the world's first automatic lunar rover to the sky. 1 After landing in the rainy sea on the surface of the moon on June 7, we went down to the surface of the moon for a scientific investigation of 10. The lunar rover weighs 756 kilograms, is 2.2 meters long and 1.6 meters wide, and is equipped with a TV camera and a nuclear device. It traveled on the moon for 1 0540m, surveyed the lunar area of 8,000m2, took 200 panoramic photos of the moon and more than 20,000 photos of Zhang Yue, and didn't stop working until 197 1 year1month 4. 197365438+1launched lunar rover 2 1 on October 8th, and sent lunar rover 2 to the moon for investigation and achieved more results. The last Lunar 24 probe was launched on1August 9, 976. 18 On August 8th, a soft landing occurred on the surface of the moon, and drilling brought back170g moon rock samples. At this point, the unmanned exploration of the moon by the former Soviet Union was completed, and people's understanding of the moon was richer and more complete.
A detector.
After the former Soviet Union, the United States launched nine rovers and seven probes. The rover probe looks like a big dragonfly, 3 meters long, and the solar panels on its wings spread out 4.75 meters. The detection instrument is installed in the front, and the TV camera is placed in the back. Surveyor has three feet, with a total weight of 1 ton, and is equipped with the most advanced detection equipment at that time. None of the first five rovers achieved any results. Ranger 6, which was launched on1964 65438+1October 30th, didn't land in the Jinghai area on the surface of the moon. However, due to the failure of the TV camera, the photo was not taken back. On July 28th of the same year, Rover 7 successfully launched and landed in the sea of clouds on the moon, and took a close-up photo of 4308 Zhang Yue. Subsequently, Rover 8, which was launched in February of 1965, and Rover 9, which was launched on March 24th, both successfully landed on the moon, and took 7 137 and 58 14 close-up photos of Zhang Yue respectively. 1966 On May 30th, the new detector surveyor 1 was launched. After 64 hours' flight, it made a soft landing in the stormy sea on the surface of the moon, and sent back 1 150 photos of Zhang Yue to the ground. In June 1 968 65438+1October1,of the seven surveyor probes launched, two failed and five succeeded. Later, the United States launched five lunar orbiters to provide detection data for Apollo manned landing on the moon. After this series of unmanned explorations, the true face of the moon was revealed.
Since Apollo 1 1 spacecraft landed on the moon for the first time on July 6, 1969. According to the results of many field explorations of the moon and the analysis of the rocks and soil brought back by the moon, human beings have learned more about the face of the moon. Scientists believe that the rocks on the moon are older than those on the earth. The moon and the earth are almost composed of the same chemical elements, but they are different in composition. For example, moon rocks contain more calcium and aluminum than rocks on earth. The moon has no magnetic field, and its shell is relatively stable, which has not changed much in the past 3 billion years. Although astronomers have always thought that the moon is petite, its gravity is weak (65438+ 0/6 of the earth's gravity) and it has no ability to bind the atmosphere at all. At the high temperature on the sunny side, any gas molecule will easily get out of speed. However, the measured data on the moon show that the surface of the moon is not a country without any atmosphere, but the atmosphere is too thin, the atmospheric pressure on the surface is only 2X 10 "bar, and the atmospheric composition is complex and changes at any time. Usually the atmospheric composition at night is mainly composed of 40% argon, 40% neon and 20% helium, and a very small amount of methane and ammonia will be added at sunrise. In some areas, the atmosphere is also American scientists have claimed that there is ice on the moon, which may provide drinking water for people exploring the mysteries of the moon, and can also decompose the ice into hydrogen and oxygen to provide fuel for rockets.
From the field exploration, it is found that there are more than 300 thousand craters scattered on the moon, which surround each other. The largest crater, nearly 300 kilometers in diameter and more than 6000 meters above sea level, is very spectacular. Unfortunately, these mountains are bare, barren and desolate because there is no water on the moon. Obviously, it is imperative to solve the water supply problem on the moon if such a desert-like moon world is to become a paradise suitable for living things and eventually become a vibrant, competitive and fragrant earth. Over the years, scientists have put forward many ideas. There is a solution: mining the iron oxide which is extremely abundant on the moon, smelting it with a solar melting furnace, releasing a large amount of oxygen, and combining it with the liquid hydrogen collected by the transport spacecraft from space to generate water for the development of the moon. This scheme of taking synthetic water from the moon and space is feasible in principle, but it is not easy to implement this huge project, which involves a series of problems such as energy, mining, transportation and life.
The most attractive thing for human beings is that the lunar soil contains a lot of gaseous "helium -3", which is a nuclear material with much lower radioactivity than the deuterium raw material used in nuclear power plants on earth at present. Helium -3 originally existed in a large number of high-energy particle streams (solar wind) ejected by the sun. On the moon with almost no atmosphere, the "solar wind" comes directly. Over time, about 654.38+million tons of this substance gathered in the sand and rocks on the surface of the moon. If it can be exploited in large quantities, it can not only provide the energy needed for lunar development, but also 265438+.
The day and night of the moon lasts for half a month, with the highest temperature 127℃ during the day and the lowest temperature-183℃ at night. Such a severe temperature difference between hot and cold is another important reason why there are no people and life on the moon. Russian scientists have made a long-term study on how to use the soil and rocks on the moon to make building materials such as cement, and then use these materials to build a living base with adjustable room temperature to make it suitable for human habitation. One scheme is that they think that the moon is probably a hollow ball by analyzing some measurement data of the moon. Based on this understanding, one day, we can dig a tunnel on the surface of the moon and enter the "underground moon palace" deep in the lunar crust, where we can build an "underground city" suitable for human habitation. In this way, tourists flying to the moon by spaceship can find hotels for the night in this "underground city". Scientific and technical personnel can take this underground city as a base to engage in activities such as lunar resource exploration, aerospace product production and astronomical observation. Before building the permanent base of the "underground moon palace", scientists suggested that some prefabricated plastic mold components could be made on the earth to form a giant cylinder that automatically rises vertically. After being assembled in advance, it will be sent to the surface of the moon by a space transport ship. As soon as the cylinder falls to the surface of the moon, it will automatically split into two halves and open, automatically forming a multi-storey building as a temporary residence for the first moon landing volunteers.

Second, the birth of the moon.
The mystery of the birth of the moon
How did the moon first form? This is a controversial issue in the scientific community. At present, there are roughly three theories.
"Captive" theory: Some scientists think that the moon was originally a meteor. When it flew aimlessly in space, it accidentally entered the range of gravity and was bound by the gravity of the earth, so it was accidentally brought into the orbit of the earth. But in recent years, many people cite celestial mechanics to oppose this statement.
"Split" theory: Scientists who hold this view believe that the moon is split from the earth and surrounded by a hot rotating cloud, so the moon is the "child" of the earth. However, the data brought back by Apollo spacecraft several times show that the composition of the moon and the earth is very different.
"Collision" theory: According to this theory, about 4.5 billion years ago, a planet larger than Mars suddenly hit the early earth at a speed of 4,000 kilometers per hour, so strongly that the iron core of this planet hit the center of our earth. The result of the collision was a huge explosion, accompanied by a high temperature above 6000 degrees Celsius. The earth was deformed by the impact of the explosion. Most of this huge suicide celestial body is integrated with the earth, and only a part of it is violently ejected into outer space as hot steam with other debris. Later, steam cooled and solidified into dust, mixed with other debris to form nuclei, and then condensed into a group, and our neighbor Grey Moon was born.
Scientists are using new supercomputers to simulate this strange collision in space to test the theory.
A new theory of the origin of the moon
Where does the moon come from? This is a question that people are constantly exploring. In recent years, with the rapid development of planetary evolution theory and the wide application of modern computer technology, a new theory of the origin of the moon has emerged, which is called the new capture theory.
On the origin of the moon from the perspective of planetary evolution
In recent years, based on the modern planetary evolution theory, scientists have calculated the forces acting on the sun, the earth and the moon in the early days of the formation of the solar system by computer, and put forward a new theory of the origin of the moon. Scientists believe that the moon was captured by the earth at the early stage of its formation within the gravity range of the earth; And this phenomenon was very common at that time. This new theory, the so-called new capture theory.
The new capture theory is different from the old capture theory. The old saying is that the origin of the moon is only considered from the gravity of the earth; The new theory studies the origin of the moon from the whole process of the formation of the planets of the solar system. The new theory holds that the nine planets and some satellites in the solar system, including the moon, originated from the primitive solar system nebula. The primitive solar system nebula is a thin disk nebula formed around the primitive sun 4.6 billion years ago. The nebula contains solid particles. A large number of particles gradually gather on the equatorial plane of the nebula, forming a thin layer of solid particles. With the increase of particle density, their own gravity becomes stronger and stronger, which destroys their stability to some extent and is crushed into many small celestial bodies with a radius of about 5 kilometers, that is, asteroids. The entire solar system was originally composed of about one trillion asteroids. Countless asteroids revolve around the sun in nebula gas, collide with each other, and gradually condense and grow, forming planets of different sizes. Our earth is like this. It took about10 million years to grow to this size.
Planets grow in nebula gas. When the earth was young, it was covered with dense nebula gas, which was called primitive atmosphere. Because of the intense solar activity at that time, the strong solar wind gradually dispersed the primitive atmosphere, and then the primitive atmosphere around the earth gradually thinned and drifted away.
The moon also originated from the primitive solar system nebula, which is roughly the same as the evolution of the earth. The moon flew close to the earth's gravitational circle when the earth just came of age and the primitive atmosphere began to escape, thus becoming a prisoner of the earth.
Four forces seized the moon.
After the moon entered the earth's gravity circle, it was forced to stay in the satellite orbit by many forces. There are four main forces to capture the moon, namely, gravity of the earth, gravity of the sun, tidal force and primitive atmospheric resistance.
Generally speaking, small celestial bodies flying into the earth's gravitational circle, including the moon, are subjected to the greatest force. However, only the gravity of the earth, the orbit of the captured small celestial body is not elliptical. After the gravity of the earth and the gravity of the sun, the orbit of small celestial bodies has changed. Under the gravity of the earth and the sun, the orbit of small celestial bodies entering the earth's gravity circle is not completely elliptical, and after flying for several weeks, they will inevitably leave the gravity circle and cannot stay in the satellite orbit.
But the moon has not left the earth's gravitational circle, which is due to the resistance of the primitive atmosphere. The primitive atmospheric resistance in the earth's gravitational circle has a sharp braking effect on the flying moon, which makes the moon lose part of its energy, and its orbital radius becomes smaller and it can't run away.
In this way, due to atmospheric resistance, the orbital radius of the moon is getting smaller and smaller. Isn't it a matter of time before it falls on the earth and collides with the earth? Don't worry, when the moon flew into the earth's gravity circle, the primitive atmosphere began to drift away gradually, and the atmospheric resistance on the moon became smaller and smaller. After the primitive atmosphere disappeared, the drag on the moon disappeared, so the orbital radius did not decrease and there was no collision with the earth.
After the atmospheric resistance disappears, there is still tidal force at work. Under the action of tidal force, the revolution speed of the moon is accelerated, the centrifugal effect is strengthened, and the orbit is outward instead. According to observation, the radius of the lunar orbit is actually increasing by about 3 cm every year.
Under the action of the above four forces, the moon did not fall to the earth after being captured, nor did it go outside the gravitational circle. It always ran in the orbit of the satellite and accompanied the earth for a long time.
Capture is a common phenomenon.
It is a common phenomenon that planets capture small celestial bodies during planetary evolution, not only on the earth, but also on other planets in the solar system. Many planets have their own satellites, which is the best explanation. During the formation of the earth, many small celestial bodies flew into the gravitational circle, some of which collided directly with the earth, and most of the others made their orbital radius smaller due to the strong resistance of the primitive atmosphere during the flight around the earth, and finally fell to the primitive earth. The earth grew up by constantly "devouring" these flying small celestial bodies.
The moon was captured later than other small celestial bodies. The moon was captured at the end of the earth's condensation and the beginning of the escape of the primitive atmosphere. Before the moon was captured 10- 100 years ago, its orbital radius was also shrinking, just like other small celestial bodies. However, after the original atmosphere disappeared, the orbital radius of the moon changed, and the centrifugal tendency of the moon in the later period enabled it to survive and avoid being "swallowed up" by the earth. French scientist F. Migouna once calculated the orbit change trend of the moon after it was captured, and the calculation results are shown in the attached figure. As can be seen from the attached figure, it is very close to the moon just photographed and the earth. After100000 years, the radius of the moon's orbit will be 20 times that of radius of the earth, 35 times after100000 years, and 60 times after 4.6 billion years, which is the present position.
Since capturing the moon, the earth has hardly captured any other small celestial bodies. Because the moon has circled the earth once, if there are other small celestial bodies flying, according to the principle of celestial mechanics, they will not be in a stable state. They either landed on the earth, flew out or landed on the moon. Therefore, the earth is accompanied by only one satellite, the moon.
Capturing is common among planets in the solar system, except Venus. Venus rotates very slowly, about once every 250 days, so it can't catch planets, so it still roams alone in the sky.
The new capture theory expounds the origin and capture process of the moon from the overall evolution of the planet, and is the most authoritative theory to explain the origin of the moon at present. However, there are still some problems to be studied in this new theory. For example, can a satellite be captured without the original atmospheric resistance? What is the difference between the acquisition of anterograde satellites and retrograde satellites? Wait a minute. After repeated research by scientists, mankind will have a correct and comprehensive understanding of the origin of the earth.

The primitive planet collided with the earth to form the moon.
On August 16, Nature published the computer simulation results of scientists on the formation process of the moon. According to their model, the moon was born when an object the size of Mars hit the earth less than 6,543.8 billion years after the birth of the sun 4.6 billion years ago.
Canapa Moore, a researcher of the model, described this thrilling process: a dark primitive planet less than one and a half times larger than the Earth met the Earth in operation and gave the Earth a blow from the side, making it rotate around its own axis. The impact of the impact tore off some materials from the outer layer of the earth and this nameless impactor, about half of which eventually formed the moon. Other torn materials are heated to unimaginable levels and expand after evaporation.
First of all, several mysteries of the moon
Mystery of the origin of the moon: At present, human beings have put forward three hypotheses about the origin of the moon, namely, the theory that the moon was captured, the theory that the earth and the moon are homologous, and the theory that the earth split. So far, the three hypotheses have not obtained strong evidence, so the fourth hypothesis "the moon" has appeared.
Mystery of Moon Age: Rock samples brought back from the moon can be used to determine the age of the moon. It is found that 99% of the moon rocks are older than 90% of the oldest rocks on earth. 1973, a moon rock was determined to be 5.3 billion years old at the World Moon Symposium, while the oldest rock on the earth was 3.7 billion years old. Some scientists believe that the moon was formed in interstellar space long before the formation of the earth.
In addition, there are mysteries about the formation of craters on the moon, the age of lunar soil is older than that of rocks, the huge noise caused by the impact of the moon, the stainless iron on the moon, and the large amount of water vapor on the dry moon.
Second, many documents record that the moon has not existed since ancient times.
Ancient American Mayans left a very developed culture, but in their chronicles, which began before the flood, people were surprised to find that there was no record of the moon.
● About 4,000 years ago, the first librarian of the Alexandria Library wrote in his literature: "In ancient times, the moon could not be seen in the sky of the earth."
● Jinzhong recorded a very surprising message: "It is a pity that in the eleventh year of Taizong Tianhui, it was ugly in October and May, and the moon suddenly lost to the south." Meaning: In the eleventh year of Emperor Taizong of Jin Dynasty (A.D. 1 133), the moon suddenly deviated from its orbit, headed south, and soon returned to its original orbit.
Third, myths and legends related to the moon.
China's myth about the moon was first recorded in Shan Hai Jing, Chu Ci, Huai Nan Zi and other ancient books.
There are many legends and fairy tales about the moon. There are stories about the Goddess Chang'e flying to the moon and Zhu Yuanzhang's anti-Yuan uprising.
Legend has it that there is a laurel tree 500 feet high on the moon. There was a man named WU GANG in the Han Dynasty who was obsessed with fairy tales and didn't concentrate on reading. He was banished to the moon to cut laurel, but laurel was cut with it, so later generations can see the image of WU GANG cutting laurel endlessly in the middle of the month.
4. China's ancient fantasy poems about the moon.
What are the advantages of luminous? Have another baby when you die. What's the use of feeling arrogant and caring for rabbits? (Qu Yuan's "Chu Ci Tian Wen")
What are the characteristics of the moon? It will die and grow again. What are the advantages of keeping a rabbit in your arms? )
In the middle of the moon, there should be clearer light. (Du Fu's "One Hundred and Fifty Nights on the Moon")
The old rabbit is cold and the toad is crying, and the half-open wall of the cloud tower is white. The jade wheel rolled with dew and wet the surrounding light and shadow. Mo Yan in Guihua Lane once met the fairy of Lu 'an-E. (Li He's Dream of Heaven)
Poor tonight, where to go, to relax? Don't ask, I'll see you there, East of Light and Shadow? Is the sky sweaty outside, but the wind is mighty to send the Mid-Autumn Festival? It is like a mirror that flies to the sky, but it won't fall off. Who tied it with an invisible long rope? Chang 'e in the Moon Palace is still unmarried. Who kept her? I heard that the moon swam across the bottom of the sea, but I can't see why. This is an unpredictable thing, but also a worrying and terrible thing. I'm afraid that the whale in the sea will hit the Jade Palace and Qionglou in the Moon Palace. From the bottom of the sea, water won't worry about water, but did rabbits ever learn to swim? If the Tao is intact, why is the cloud gradually like a hook? (Xin Qiji's "Magnolia Slow")
Fifth, enjoy the moon.
● The moon is bright, and August is particularly bright; Beautiful mountains and mountains, Wushan Xiu Xiu is very.
● Enjoy the moon in the Mid-Autumn Festival, and the full moon is missing; A wanderer is homesick, but his hometown is sweet.
● Full moon in the sky, half moon on the ground, and each moon has half moon; Tonight is the end of a year, tomorrow is a year, and year after year is the end of a year.
● Big Dipper, water reaches 14; There are geese in the south building and a pair of flies in the moon.
● Although the building is high, Ren Yunfei has passed; Small pool can send the bright moon.
Flowers and shadows are everywhere; A pavilion of mountains, mountains, colors and moons peeps at people.
● The water is cold and warm, where to find the source of the stream, the song is slanting, and the lake light can be used as a guide; Because of the full moon, Mo Wen next to the pavilion will take the first photo at the beginning of the year and propose a toast tonight. Does Chang 'e in the sky recognize me?
Sixth, the reputation and nickname of the moon.
Jade rabbit, luminous, Su E, ice wheel, jade wheel, jade toad, ghost woman, toad, ancient rabbit, Chanjuan, jade bow, jade laurel, jade plate, jade hook, jade mirror, ice mirror, Guanghan Palace, Chang 'e, jade sheep, etc.
Seven, the legend of the moon alien civilization
Legend has it that Armstrong, who landed on the moon, suddenly said with surprise when he contacted the command center code-named Houston: "These things are amazing! God, I can't believe it. I want to tell you that there are other ships here. They were arranged on the other side of the crater. They are on the moon. They are watching us ... "At this moment, the telecommunication signal suddenly stopped. What did Armstrong see?
●1968 65438+February 2 1 day, the United States launched its first probe spacecraft to the moon at Kennedy Space Center. After the spacecraft entered the lunar orbit, the astronauts took the first photo of the back of the moon with a telescope camera at an altitude of 100 km. Many years later, when people were studying these photos, they accidentally found a huge round object in the crater. It is very regular, unlike a natural thing, it looks like it is landing or taking off.
● Since apollo 8, 10, 1 1, 16 and 17 have all witnessed or photographed UFOs on the moon. Even as early as 1966, the American lunar orbiter 2.
