Moon moon, also known as the moon, ancient lunar refers to a satellite orbiting the earth. Age of about 46 billion years. It is only satellite earth and closer to earth objects, and the average distance between the Earth is 384,400 km. There are a number of ancient myths about the moon, such as Poetry and literature related to the Moon-ho, if sea smoke, most notably, Li Bai's Comparative study, In addition, China developed a thorough and practical exploration, mission to the moon.
phrases from words to explain: the moon 【English】: The moon 【Pinyin】: yuè liàng 【French】: lune basic interpretation [moon], commonly known as the moon, as bright and name. Detailed explanation of the moon known. Usually refers to the bright part, it said. Li Yi Tang a phrase, who lunar essence. However, the lunar world village who made unnecessary, through that of the moon. Tang Li Yi poem Learning phase is not observed, then into months if the name carry on. Or we can say on children. tectonic movement of the moon and the moon phase of the moon's mysteries related to lunar exploration spacecraft Surveyor probe the origin of humans on the moon to explore the mystery of the birth of the moon the moon that the moon originated several new mysteries related to the legend the legend of myths and legends of alien civilizations myths about the moon, poem describes a basic introduction to the moon poems related to earth's only natural satellite, is the closest celestial body, its average distance from Earth is about 384,401 km. It has an average diameter of about 3476 km, than the Earth diameter of 1 / 4 slightly larger. the moon surface area 3,800 sq km, while significant, but less than large area of Asia. the quality of about 735 billion lunar million tons, the equivalent of Earth's mass is 1 / 81, the lunar surface gravity equal to Earth gravity is about 1 / 6. the moon orbits the moon in an elliptical orbit around the Earth running. The orbital plane of the celestial sphere great circle intercepted the ecliptic plane, and spatial location is constantly changing. orbital period 27.32 days. the surface of the minimum temperature is -183 degrees Celsius. the moon's rotation and in around the Earth to the simultaneous rotation, periodic 27.32166 days, happens to be a stellar month, so we see not see the moon on the back. This phenomenon we call % of the lunar surface. primarily for the following reasons: 1. in the different parts of the elliptical orbit, rotation speed and rotation speed does not match the public 2.. White Road and equatorial angle. the physical condition of the moon --- the moon's surface topography are: Crater The name is called Galileo. It is the salient features of the lunar surface almost covered the entire lunar surface.'s largest crater is a crater near the south pole of the Bailey, diameter 295 km, is also larger than the Hainan Island. small craters and may even be a few centimeters of the pit. diameter of not less than about 1,000 meters 33,000. accounting for 7-10% of the lunar surface. There is a 1969 Japanese scholars crater classification, divided into clavulanic type (the old craters, generally beyond recognition, some of the mountains there are mountains) Copernican model (the young crater, often Jimi De-shaped (lower ring wall, possibly evolved from the Copernican model) and the dimple-type bowl (small craters, and some less than one meter in diameter.) ########## eye can see on the sea surface on the dark part of the actual lunar surface is a vast plain. Due to historical reasons, the name of this unworthy of the name reservation to the present. has identified 22 of mare, in addition to some of the terrain known as Distribution of the 22 most recognized face in the moon. the back 3 and 4 in marginal areas. in the front sea area slightly larger than 50% of the month, the largest of the the total area of nine French. Most of mare roughly circular, oval, and closed four weeks more to live for a number of mountains, but there are some sea is contiguous. In addition to the similar much more. mare stretched part of the land known as the , Phytophthora marsh, marsh dream of three, in fact, no difference between marsh and bay. generally low-lying on the sea, similar to the basin on the planet, the moon than the average mare surface low 1-2 km, the lowest sea of individual rain around the southeastern part of the sea and even lower than 6,000 meters. the penetration rate of the lunar surface (a measure of the ability to reflect sunlight physical quantity) is also relatively low, and thus looks darker now too. mountains on the mainland and on the surface above the lunar maria Lu called on the region, it is generally higher than the level surface of mare 2-3 km, due to its high penetration, which seems brighter. In front of the moon, on the area of land roughly equal mare. The moon has Many subsidence pits, a reflective effect. But in the back of the moon, on the area of land greater than the mare. January land from isotopes that much older than the mare, is the oldest lunar topography. on the moon , in addition to the many craters cross canines, but also there are some similarities with the Earth's mountains. mountains on the moon on the earth mountains often borrow names, such as the Alps, Caucasus, etc., of which the longest is the Apennines mountain range , stretching 1,000 km, but high but level surface than the third year mare, four kilometers. Mountains are also some peaks of mountains, past the high estimate of their height. Now that most of the peak height and peak height similar to the Earth, the highest peaks (also near the lunar south pole) is nothing but 9000 meters and 8000 meters. lunar surface peaks above 6,000 meters have six ,5000-20 ,4000-6000 m 5000 m there are 80, 1,000 meters above a 200. mountains on the moon has a common characteristic: both sides of the slope is very asymmetric, the side slope to the sea is very large, sometimes shaped cliff, the other side is quite flat. In addition to mountains and Hills, the lunar surface there are four cliff cliffs hundreds of kilometers long. which highlights three months the sea, this cliff, also known as a beautiful a lot of attention is the crater Tycho's rays, the longest length of 1800 km, the full moon is particularly spectacular. Secondly, the two craters Copernicus and Kepler also very beautiful rays. According to statistics, with the radiation pattern of the crater 50. causes the formation of radiation patterns have not fixed. In essence, the formation of craters theory it closely. Now many people are inclined to the meteorite impact that, say, in the absence of atmosphere and little gravity on the moon, fragments of meteorite impact could cause high temperatures to fly very far. while some scientists believe can not rule out the role of volcanoes, volcanic eruptions may also be the time of the formation of jet flying around the radiation shape. Moon Valley (month gap) has many well-known on the earth crack Valley, such as the Great Rift Valley. also have this structure on the surface that appears winding ---- big black crack that is Moon Valley, which stretches a few hundred to some thousands of kilometers in width from a few thousand ranging from meters to tens of kilometers. Those on a wide valley mostly in the area on relatively flat land, and those narrow valley on the smaller (sometimes also known as May River) are everywhere. the most Valley is famous on the southeast crater Plato links the sea and the cold rain sea-Alpes Valley, which on the surface of the Alps to cut down the middle, it is spectacular. from the looks of the photo space is estimated that up to 130 km wide and 10-12 km. The moon itself is a movement from west to east direction of revolution around the Earth, so the fall of the East or the West. However, the direction of the Earth's rotation is from west to east, so the result for us the actual visual effect to become the moon fell Dongsheng West. substances commonly known as the moon introduces the Moon, also known as lunar. the moon's age is about 4.6 billion years, Earth go hand it is closely related. the moon has crust and mantle, nuclear, etc. hierarchy. outermost monthly average thickness of about 60-65 km of crust. lunar crust to 1000 kilometers below the depth of lunar mantle, which accounts for most of the size of the moon. month following the month the nuclear mantle, the temperature on the nuclear about 1,000 degrees, is likely to be molten. Moon diameter of about 3476 km, the Earth 3 / 11. volume is only the Earth 1 / 49, mass of about 735 billion tons, the equivalent of Earth's mass is 1 / 81,
cheap christian louboutin, month surface gravity is almost equal to Earth's gravity is 1 / 6. the moon above a dark and bright parts of the region. early astronomers to observe the moon, dark areas that are covered by water, so they are called . loaded into it. deepest mountain is Newton crater, depth of 8788 meters. In addition to craters on the surface but also ordinary mountains. mountains and deep valleys are stacked, do not have some scenery. the moon is always facing toward the Earth. On the other hand, in addition to the lunar surface The area around the edge of the room due to libration visible outside the back of most of the moon is not visible from the Earth. In the absence of the detector's, the back of the moon has been an unknown world. the moon on the back of a major feature is that it almost does not May this dark mare surface features. and when to run to the moon on the back of the detector, it can not communicate directly with Earth.
surface temperature (t) -233 ~ 123 ℃ (average -23 ℃) 1.3 × 10-10 kPa atmospheric pressure for about one lunar month the moon around the earth to run a week, and half an hour moving relative to degree of background stars, ie similar to the lunar surface as the diameter. and various other satellites, the moon's orbital plane than the close to the ecliptic plane, not in the vicinity of the Earth's equatorial plane. relative to the background stars, the moon around the Earth is running (the moon revolution) a week time is called a sidereal month; and the next new moon and new moon (or the same two months phase between) the time required is called a lunar month. synodic month is longer than the sidereal month during operation on the moon because the earth itself is also moving forward around the track at some distance. because the moon's rotation period and its orbital period is exactly the same, we can only see the moon always faces the Earth with the same. Since the early formation of the moon,
louboutin sale, the moon has been caused by a torque of the rotation slowed down, a process called tidal locking. also, therefore, part of the angular rotation of the earth momentum into the Moon revolution around the Earth's angular momentum, the result is the moon at an annual rate of about 38 mm away from the Earth. while the Earth's rotation slower and slower, longer day length of 15 microseconds per year. the moon on the Earth Shi Gravity is one of the causes of the tide.'s orbit around the Earth to the Moon orbit is not strictly so-called synchronous rotation. As for the elliptical lunar orbit, when the moon is in perihelion, its rotation speed will catch up with the revolution speed, Therefore, we can see the lunar longitude 98 degrees east of the area, on the contrary, the month in the aphelion, the rotation speed faster than the revolution, so we can see the moon's surface by 98 degrees west region Darcy. This phenomenon is known as libration . Also, because the tilt in the Earth's equatorial lunar orbit, the moon moves in the sky, the polar regions will be about 7 degrees of shaking, a phenomenon known as libration. Furthermore, as the moon from Earth is only 60 Earth radii away, If the observer observing from moonrise to moonset, observation points will have a diameter displacement of the earth can be more common on areas of 1 degree longitude. This phenomenon is known as libration. Strictly speaking, the Earth and moon around the common center of mass operation, the common center of mass from the center of the Earth 4700 km (the Earth radius 2 / 3). the common center of mass in the Earth's surface, the Earth around the common center of mass movement like the Earth and the Moon are welcome clockwise rotation; but also to greet the moon around the clock to run; and even the earth around the sun is to greet the public and turn clockwise. Many people do not understand why the moon and the lunar rotation axis inclination angle values will be such a big change. In fact, the orbital inclination relative to the central body (the Earth) for the purposes of, the rotation axis is inclined relative to the satellite (ie the moon) its orbital plane. in this definition is suitable for general, habit (eg, artificial satellite orbit) and is fairly constant value, but the moon is not the case.
moon's orbital plane (white road surface) and the ecliptic (the orbital plane of revolution of the earth) to maintain 5.145 396 ° angle , while the moon's rotation axis is normal to the ecliptic plane and into the 1.5424 ° angle. because the earth is not perfectly spherical, but more bulge at the equator, so the white pavement in constant precession (that is, the intersection of the ecliptic in the clockwise rotation) every 6793.5 days (18.5966 years) completed a week. period, and white face to the Earth equatorial plane (Earth's equatorial plane by 23.45 ° tilt to the ecliptic plane) angle will be 28.60 ° (ie 23.45 ° + 5.15 °) to 18.30 ° ( is 23.45 ° - 5.15 °) between the changes. Similarly, the Moon's rotation axis and the angle between the road surface will be white between 6.69 ° (ie 5.15 ° + 1.54 °) and 3.60 ° (ie 5.15 ° - 1.54 °). Moon track these changes in turn affect the Earth's rotation axis inclination, it appears ± 0.002 56 ° swing, called nutation. white pavement and intersection of the ecliptic plane is called on the intersection of two - one of the ascending node (North Point ) refers to the moon by that point to the north of the ecliptic plane; descending node (South Point) refers to the Moon to the ecliptic through the south of that point. When the moon is just the intersection of the month when the solar eclipse occurs; and when the full moon just before intersection month when the eclipse occurs. away from the sun in the direction of the Earth will appear a shadow, called the shadow. umbra and penumbra of the shadow into two parts. umbra is not subject to direct sunlight place, and only the penumbra of light by some direct sunlight. the moon around the earth in the process sometimes runs into the shadow, which produce a lunar eclipse. When the moon entered the umbra are when the total lunar eclipse will occur; but If only part of the time into the umbra, the eclipse will occur. In total lunar eclipse, the moon is not completely invisible, which is due to sunlight through the Earth's thin atmosphere are refracted into the umbra, projected onto the lunar surface , and so to appear before January of red copper. the basic features of the Moon from the Earth to the Moon gradually annual rate of three centimeters away from the Earth, billions of years ago,
louboutin shoes, the distance between it and the Earth is only half as long now. the moon from Earth is currently about 60 times Earth's radius. However, due to tidal forces between Earth and the impact of the Moon, the Moon at an annual rate of about 3 cm away from Earth slowly. On the other hand, the Earth's rotation rate is gradually slowed down. That is the past is now closer to Earth than the moon, and Earth's rotation rate faster than it is now. scientists found evidence on the the formation of tree-ring growth of the same side stripes, the number and width of the stripe size varies according to moisture. According to the number and width of these provisions, the scientists found that about 5 million years ago, the Earth day only 21 hours, 1 year has 410 days . the moon's structure, according to conjecture, the moon may be hollow. Moon was the ice planet, the earth touches may be attracted by the earth, with the track. in the detection of the moon, found that being attracted to the earth, surface cracking, water tilt out of the Earth's inspection. Moon Movement and the definition phase of the moon phase of the moon as the moon in the sky every day moving from west to east in a great distance, its shape is continually changing, and this is the moon phase changes, called the moon phase. moon phase astronomy of the moon for the earth to see the sun lighting part of the call. the moon around the earth movement, the Sun, Earth, the moon's relative position in the three month change regularly. Earth to see people , is part of sunlight illuminate the shape of the moon also changes regularly, resulting in the phases of the Moon. Another reason is that the moon does not shine, opaque. the moon rotates around the Earth, the Earth, moon, sun, keep the relative position of changing. because the Moon itself does not light, bright part of the moon visible part of sunlight is reflected. Only the moon is directly part of the sun to reflect sunlight. We see from different angles, the moon is part of direct solar radiation, This is the source of the moon phase. phase of the moon covered the sun as the Earth was not created (this is the eclipse of the moon), but because we only see the sun shine on the moon is caused by that portion of light, its shadows the dark side of the Moon himself. causes of the moon phase by reflecting sunlight illuminated by the moon, it is different with the relative positions of the sun (yellow by the poor), will be showing a variety of shapes. As shown, in position a, yellow sun and the moon by difference of 0 °, that is called new moon or new moon, then to the dark side of the moon toward the earth, and the sun come and go almost the same time, the surface can not see the old haunt; c 90 ° when the longitude difference, said winding, half-moon appeared in the middle of the night sky in the west; e when the longitude difference 180 °, that is, look, or say the full moon, a moon visible all night; g for the bottom chord, yellow error by 270 °, then the half only half a day in the midnight sky appeared in the East . synodic break the cycle, said the lunar month, about 29.53059 days. the moon's motion moon around the earth called the Moon's revolution. the moon's motion is from west to east, and its track with all orbits as is oval shaped, from the Earth the nearest point called perigee, the point farthest from Earth is called apogee. westward movement of the moon each Xi Chen's evidence is that it delayed an average of 49 minutes time, if the relative star, it's exercise cycle is about 27.3 days that in this time, it is operating in space 3600; but at the same time the Earth has been constantly running around the sun, the moon to complete one phase of its cycle, from new moon through full moon and new moon to be back soared to more than two days, for a total of about 29.53 days. So the moon cycle of about 27.3 days sports stars, called sidereal month; and the relative movement of the Sun-Earth line cycle is about 29.53 days, called the lunar month; lunar month is the month basis. from the Earth view the moon, it seems that the moon does not spin, because it is always the same face of the earth, because you always see the same spots, that is, coincided with its orbital period equal to: if the revolution and rotation of the moon is equal, when the moon after a quarter of its orbit, it is itself a 900 rotation arc spots on the moon at this time that the Earth is just the opposite; Conversely, if the moon does not spin, then spots the moon as seen from Earth, it will turn a week each month, you will not always see the same spots on the moon. the surface of the moon the moon phase change is composed of rock and dust, It is not light and the Earth as their own, so we see the moon phase is part of the moon reflecting the sun, since the new moon phase in the lunar month of the change order: Moon, winding, hope and bottom chords. in the lunar months, counting the length of time since the new moon is called the lunar month, such as the look of the lunar month of 14 days and so on. before and after the new moon seen from Earth appear before sun crescent moon-shaped, bent on wheels can be seen demi, And look before and after the moon was sunshine part of the convex rounded, waxing and waning moon is different, because winding seen from the Earth of its monthly round of the West, demi, and see when is the last quarter of its East demi . The moon is Earth's satellite, the moon, between the earth and the sun, the moon around the earth constantly rotating, and when it go to the middle of the Earth and the Sun, it was half the sunlight that illuminated just carrying the earth, toward the Earth is the dark half, when we are on Earth can not see the moon, known as the at sunset, the moon has been in the head, to the middle of the night before the moon went down, and when illuminated by the sun, the moon, just half of you see, called the Go to the other side of the earth. when the Earth between the sun and the moon, the moon half lit by the sun looks on the earth, then we see the full moon, or so-called opposite the sun in the west so the sun sets, the moon rises from the east, to the moon falling, the sun and from the east increased. full moon after the time the moon rises late every day, every day is also part of the moon light see the small, to the lunar calendar xxiii loss to the half full moon, and only rose up at midnight, this is the Soon, the moon rises in the east before another. to the first day of next month, but also a new moon, start a new cycle. relevant to explore the mysteries of the moon from the earth than the moon is a celestial body, there are 38.4 million km away. Astronomers have long telescope a good look at the moon, the moon is almost well known terrain. the moon has mountains and plains, there are numerous pits and gully aspect, but there is no air temperature disparity between day and night, a dead and desolate. While the telescope can distinguish the giant moon 50 meters on the target, but still not as clear as faithfully visits. Thus, the first human to send envoys to visit the remains of extraterrestrial objects selected on the moon. the United States as early as August 18, 1958 launch lunar probe, but since the first stage rocket launch explosion, died halfway. then they have launched three Pioneer spacecraft, were unsuccessful. January 2, 1959, the former Soviet Union launched the 1st lunar probe, the way the flight goes well, January 4 from 7500 km from the lunar surface where by, unfortunately, failed to hit the moon. The probe weight 361.3 kg, fitted with the most advanced communications, detection equipment. it became in the 9 months to fly the first artificial planet deep space. moon on the 1st two months after the launch of the March 3rd, the 4th United States launched the Pioneer probes, from 60,000 km away from the lunar surface where flying and did not hit the moon. lunar spacecraft from 1958 to 1976, the Soviet lunar spacecraft launched 24, 18 of which completed the task of probing the moon. September 12, 1959 launch of lunar 2, two days later flew to the moon in the lunar surface Chenghai hard landing, becoming the first messenger to reach the moon, the first time from Earth to another celestial body in flight. It contains the scientific instrument compartment of the radio communication device, the work stopped after the impact the Moon. the same year, October 4 Luna 3 spacecraft to the moon, the moon around the back 3 days later, shot back the first pictures of the moon, the first people to see the whole face of the moon. the world's first soft landing on the moon probe, was January 31, 1966 launch of the moon on the 9th. It is a long flight after 79 hours after the moon's Ocean of Storms near the landing of the lunar surface with a video camera pictures. The probe weight 1583 kg, reaching 75 thousand from the lunar surface m, weight 100 kg lander and probe body separation, mounted by the inflated balloon slowly out of the automatic landing success. September 12, 1970 launch of the moon on the 16th, September 20th in the lunar soft rich Hai landing, the first collected using a drill core samples 120 g on the mouth into the recovery tank sealed container, on the 24th back to Earth. November 10, 1970, carrying the moon on the 17th the world's first automatic car Moon car days. 17 in the lunar Imbrium After landing, the lunar vehicle on the 1st down to the lunar surface for a 10 and a half months of scientific investigation. Zheliang lunar vehicle weight 756 kg, length 2.2 meters wide and 1.6 meters, equipped with a TV Camera and nuclear energy equipment. It travel 10,540 meters on the moon, study lunar 8 one thousand square meters area, shooting a 200 panoramic photograph the moon and 20,000 more than the lunar surface photos, until October 4, 1971 before running out of nuclear energy stop working. January 8, 1973 launch Moon, 21, to send the rover on the 2nd study the lunar surface for more results. Finally, on the 24th of a lunar probe on August 9, 1976 launch, August 18 at Wei Hai lunar soft landing, drilling and samples of lunar rocks brought back to 170 grams. At this point, the former Soviet Union's unmanned exploration of the Moon declared completed, it is a richer understanding of the moon and complete. Surveyor probe following the former Soviet Union, the United States later, has launched Ranger No. 9 and 7 lunar probe Surveyor. wandering detectors look like a big dragonfly, length 3 meters, the two wings of solar panels to start 4.75 meters. detection equipment installed at the front, TV camera on the tail. Surveyor probe has three legs weighing a total of 1 ton, with the most advanced detection equipment. the first detector 5 Prowler no contribution until January 30, 1964 launch of the wandering by the 6th before landing in the lunar Sea of Tranquility region. but because of TV cameras failed, not able to take back to the photo. In the same year on July 28 was successfully launched on the 7th Prowler, sea of clouds in the lunar landing, lunar surface captured close-up photos 4308 . then February 17, 1965 launch of the Ranger 8 and March 24 launch Prowler 9, were successfully landed on the moon, and were taken back to the 7137 and 5814 close-range photograph the lunar surface. 1966 5 30 launch a new investigation by the 1st probe, after 64 hours of flight, the Ocean of Storms in the lunar soft landing, the ground surface months back 11,150 pictures. to January 1, 1968 launch of the seven Surveyor probe device, there are two failures, 5 success. Later, the U.S. launched five Lunar Orbiter Central Bank, the Apollo manned lunar landing sites selected to provide detection data. After this series of unmanned exploration, the moon true colors revealed. Since July 16, 1969 the United States, multiple-site exploration and brought back moon rocks from the soil analysis results of the study, the human face of the moon has a greater amount of understanding. Scientists believe that the moon rocks are even older than the Earth, the Moon and the earth is almost the same chemical elements, only the composition of the ingredients are different. For example, the lunar rocks contained in the calcium and aluminum than rocks on Earth, and its content is higher, the moon is no magnetic field, the shell is relatively stable, nearly 30 million years almost nothing has changed. Although astronomers have long believed that the moon petite body, weak gravity (the earth is 1 / 6), does not have tied the ability of the atmosphere, in the sunny side of the high temperature, any gas molecules will be easily reached from the speed of escape. but the test shows that the moon, the moon has no atmosphere, the surface is not the country is not speed, but the atmosphere is too thin, the surface atmospheric pressure is only 2X10 variable, usually at night when the atmospheric composition mainly 40% argon, 40% and 20% of the helium neon composition will be added to the sunrise, a small amount of methane and ammonia, but also the atmosphere in some areas found a very small amount of hydrogen, radon, sodium, and potassium atoms such as polonium. U.S. scientists recently claimed that there is ice on the moon, which may explore the lunar mysteries that provide drinking water, the ice can also be broken down into hydrogen and oxygen, thus providing fuel for the rocket. Found from the field exploration, the moon a total of more than 30 Manza crater, dotted, embracing each other, the largest crater,
red sole shoes, nearly 300 km in diameter, up to 6,000 meters above sea level, very spectacular. Unfortunately, because there is no water on the moon, the mountains are bare,
christian louboutin shoes, barren, very desolate. Clearly, in order to make this world a desert moon paradise for living things, and ultimately become a vibrant, competitive deposit things, flowers of heaven and earth, it is imperative to solve the problem of water supply on the moon. For years, scientists have proposed several ideas. One solution is: mining stocks on the Moon very rich iron oxide, melting furnace smelting with solar, it released a lot of oxygen, and transport system of the spacecraft collected from space taken by the combination of liquid hydrogen, to generate for the Moon development needs of the water. The use of local materials on the moon and space, synthetic solution of water, is feasible in principle, but to implement this huge project, is by no means easy, involving energy, mining, transportation, life and other issues need to complete solution. The most attractive humans, is the lunar soil contains large amounts of gases like with the 1 million tons of such material, if the large number of mining, not only the energy needed for lunar development, but also for the 21st century global nuclear fusion to provide unlimited raw materials. The Moon during the day and night for up to half the duration of all years, daytime temperatures up to 127 ℃, the night temperatures are as low as minus 183 ℃, the drastic changes in temperature so hot the weather cold but, no signs of human habitation on the moon and the life of another important reasons. Russian scientists have been on how to use the lunar soil and rocks on the manufacture of cement and other building materials, construction and use of these materials, one can adjust the room temperature, making it suitable for human habitation, life made a long-term research base. One solution is that some of them to the moon by analyzing measured data that the moon is likely to be a hollow sphere. Based on this understanding, one day, you can play a passage on the lunar surface, lunar crust into the depths of the Thus, travelers flying to the moon take the spacecraft can be in this Scientists can engage in this underground city as a base for exploration of lunar resources, space, production, astronomical observation and other activities. In the After the pre-assembled, with the universe to the lunar surface transport ship, a landing on the lunar surface cylinder is automatically divided into two halves open, and automatically form a multi-storey building structure, as the Moon debut of . Man on the moon to explore the moon first man-made object to reach the former Soviet Union's unmanned lunar lander 2, it was September 14, 1959 crashed into the lunar surface. Luna 3 October 7 in the same year the moon on the back of the photo shoot. Moon on the 9th is the first soft landing on the moon lander ship it on February 3, 1966 return from the lunar surface photographs. In addition, the moon on the 10th in March 31, 1966 successfully into orbit, becoming the first artificial satellite the moon. During the Cold War, the United States and the former Soviet Union had been hope that the other leading technology in space. This space race in the July 20, 1969 when the first human landing on the moon climax. United States of America Apollo 11 commander Neil Armstrong was the first person to set foot on the moon, and Eugene Cernan is the last man standing on the moon, he was in December 1972 Apollo 17 mission members. See also: List of Apollo 11 astronauts to the moon the astronauts left a 9-inch by 7-inch stainless steel plaque on the lunar surface, to commemorate the landing and it is likely to be found in other organisms to provide some information. Back in 1898, the famous biologist Charles Darwin's son George Darwin in out, after the formation of these substances from the earth to the moon, and left in the earth pit, is now the Pacific Ocean. This view soon received some opposition. They believe that the Earth's rotation speed is not as big as the one to throw things go. Furthermore, if the moon is thrown to the earth, then the two material components should be consistent. But on There is also a close to capture that view is that orbit the Earth continuously to enter their own accretion of material together, over time, accreting more and more things, and ultimately the formation of the moon. In the accretion process, corresponding to the Earth than the moon a little faster, a This assumption has also been the objective existence of challenges. Through the The two objects in their evolution, were formed of iron-based metal-core and formed from the silicate mantle and crust. Since these two objects not far, so great opportunity to meet. By chance, the smaller objects to the rate of about 5 km per second crashed into the Earth. Rupture upon impact with the mantle separation of the metal core, due to the resistance of the gas expansion left the rather slow, about 4 hours by accretion to the Earth.
