The moon origin mystery: for lunar origins, scientists put forward three kinds of theories: capture said, homology and earth divided them all defective, said, but the Apollo would help proof, which seem least likely theory is the best theory. Some scientists think, the moon is with earth in 46 billion years ago, from a group of cosmic dust generator. Another theory is that the moon is the earth's "children", is perhaps the Pacific "dig" out. However Apollo moon exploration results show that the earth and the moon the composition of the difference is very big, some scientists have proposed another hypothesis, namely "captured". They think that the moon is accidentally broke into gravitational field, and be locked in the present orbit. However, it is theoretically explain the process mechanism, is extremely difficult. Therefore, the above three theory all difficult to hold water. As robin hallam especially by dr said: "to explain the moon does not exist, than to explain the moon exist easier."
The moon age riddle: what is amazing is that the rock samples from the moon back, via analysis found that about 99 percent age than earth 90% oldest rocks more older. Armstrong in "quiet sea" after landing picked up the first piece of rock's age is 36 billion years old. Some other rock age 4.3 billion years old, 4.6 billion years old and 45 billion years old — — it almost and earth and solar system itself, the earth is as old as the oldest rocks is 37 billion years old. In 1973, the world symposium on the moon was a age determination for 53 billion years old of moon rocks. Is more surprising is that these ancient rocks are collected from scientists believe to be the youngest area on the moon. In light of the evidence, some scientists propose that the moon on earth formed before long was established in interstellar space formed.
The lunar soil years older than rock greater mystery: the moon ancient rock has made scientists helpless, however, and these rocks, compared to the surrounding soil rock is young. According to the analysis, soil age at least 10 years than rock. At first glance, sounds, this is impossible because scientists think these soils are rock after smashing formation. But, determination of rock and soil chemical composition, the scientists found that, after the soil and rock is irrelevant, seem to come from elsewhere.
When a massive object when the moon, the moon hit send hollow balls like voice mystery: in Apollo exploration process, abandoned the rockets third quarter thrusters will boom the bump on the surface of the moon. According to NASA document records, "each such noise, sounds like a big the sound of the bell". When the moon landing in color special personnel black plains, they found on the surface of the moon drilling very difficult. Soil sample by analysis found that, which contains a large number of rare earth metal titanium (it was used in the supersonic jet and spacecraft on); Others, such as zirconium, hard metal iridium, beryllium content is also very rich. This makes scientists puzzled, because these metal only in high temperature — — about 45 degrees Fahrenheit, will and surrounding rock as a whole.
Stainless iron mystery: lunar surface rock sample still contain among them pure iron granules, scientists think they are not from meteorites. The former Soviet union and American scientists has found a more strange phenomenon: these pure iron granules on earth put seven years is not rust. In the scientific world, didn't rusty pure iron is unheard of.
The moon radioactive mystery: the moon in thickness of eight miles surface is radioactive, this also is a astonishing phenomenon. When "Apollo 15th" astronauts using temperature timing, they found reading extraordinarily high, which suggests that Italy plain nearby heat flux indeed temperature is very high. A scientist exclaimed, "oh god, this land will soon melted! The moon's core must be more hot." However, is it surprising is that month heart temperature is not high. The heat from the surface of the moon of radioactive substances emit, but these radioactive substances (uranium and plutonium, thallium) and where do you come from? If they are from the heart, so how could they on to the surface of the moon?
Dry on the moon is large hydrosphere mystery: the first few times that the moon, the moon is a dry celestial bodies. A scientist had assert that it than the gobi desert dry 100 million times. Apollo missions of the first few times are not on the surface of the moon found any water trace. But "Apollo 15th" scientists has detected the surface of the moon is one place 100 square miles of water gas. Scientists red face argue that this is the American astronaut waste in the moon two small tank leakage causes. But such small tank can produce such a large hydrosphere? Of course this is not astronauts — — it directly spray urine to the moon in the sky. It seems that these moisture from the moon internal.
The surface of the moon is glass shape puzzle: Apollo astronauts discovered many places, the surface of the moon is covered with glass shape material, which suggests that the surface of the moon appears to be burning fiery fireball. As one scientist has pointed out, "the moon with glass." Expert analysis proof, this layer of glass of substance is not huge meteoritic impact generated, some scientists believe that, this is the explosion of the sun — — some miniature nova state — — consequences.
The moon of the magnetic field mystery: early detection and studies show that the moon, but almost no magnetic field of moon rocks analysis has proved it had strong magnetic field. This phenomenon makes scientists dumbfounded Paul jester doctor declared: "here is very strange magnetic rock... is quite beyond our expectation." If the moon had magnetic field, it should have an iron core, but of reliable evidence shows that the moon may not have such a core, And the moon will not possible from other objects (such as earth) obtain magnetic field, because if it is indeed the case, then it must be very close from earth, then it will be gravity ripped to pieces.
The moon internal mysterious "material aggregation point" mystery: 1968, flying around the moon, the moon probe the first to show the below the surface exist "material gathered structures". When the spacecraft flying over these structures over, due to their great gravity, shuttle flight will slightly below the prescribed orbit, but when the ship leave these structures clouds, it will speeding slightly, it clearly shows that the material gathered structure exists, and their great quality. Scientists think, these structures is like a bull 's-eye, by heavy elements constitute, hidden in the surface of the moon "hai" below. As one scientist has said: "it seems that who also don't know how to deal with them."

On Sunday, several hundred engineers and scientists will gather at the Jet Propulsion Laboratory in Pasadena, Calif., and await the end of the Galileo spacecraft in a suicide plunge into Jupiter''s dense atmosphere.
周日，数百名工程师和科学家,将聚集在加利福尼亚州的帕沙德纳的喷气推进实验室，静候伽利略号航天飞机自杀性插入木星周围稠密大气层的结局。
They are the kind of professionals who try to resist anthropomorphizing their machines, even one like Galileo, which has been a longtime companion in their lives and careers. But they freely concede that they will be there at the end as an act of homage.
这些专家尽力阻止使机器人性化，即便是相处很久的伽利略号。但他们不得不勉强的承认他们会满怀敬意的守到最后时刻。
"It will be the equivalent of a wake," said Dr. Claudia Alexander, manager of the project.
“它将是一个有意义的轨迹”，这个项目负责人Claudia Alexander博士评论道。
Few flight teams have had to contend with a spacecraft more demanding of their attention and ingenuity.
很少飞行队要求航空飞船有更多的注意力和灵活性。
Launched in 1989 after a long delay caused by the loss of the space shuttle Challenger in 1986, Galileo took six years going to Jupiter, almost half a billion miles away, by a circuitous route dictated by the limited power of its initial rocket boost.
由于1986挑战者号航空飞船的坠毁，推迟了很久的伽利略号终于于1989年发射。它花了6年的时间到达木星，几乎走了5亿英里距离。
From then on, the three-ton spacecraft was tormented by as many afflictions as poor Job.
从那时起，3吨重的航空飞船被认为是一项要多痛苦有多痛苦的乏味工作
The main antenna, the one that scientists counted on for the return of pictures and data of Jupiter and its four largest moons, failed to unfurl. Engineers had to rely on a smaller antenna and an improvised system of data shorthand.
科学家们所指望的用于返回木星和他的四个最大的卫星的和数据的主要天线没能正常打开，因此他们不得不依靠一个小型天线和一个临时准备的数据速记系统。
Galileo was further hobbled by an erratic tape recorder. After the craft began orbiting Jupiter in 1995, repeated zappings from the planet''s intense radiation belts damaged other instruments.
伽利略号又被一个漂浮在太空的磁带录音机所拖累。在飞船1995年后围绕木星轨道运动时，从行星的强辐射带发射的循坏的跳过节目的辐射损坏了其他一些仪器。
In nearly all cases, engineers managed to reprogram software to overcome or work around the setbacks. As recently as last November, in its last encounter with a Jovian moon, tiny Amalthea, the spacecraft "got hammered again by radiation," Dr. Alexander said.
在所有的情况中，工程师们试图重新编写软件以克服遇到的挫折。去年十一月份，在它的最后一次与木星的卫星木卫五相遇时， “飞船又被辐射给破坏了,” Alexander博士说。
The spacecraft''s fault-detection system came to the rescue once again, turning off nearly all operations and saving the science data from the encounter.
飞船的错误监察系统再次起了作用：它几乎关闭了所有操作并将相遇的全部科学数据记录了下来。
But the tape recorder was left stuck. Flight controllers applied electrical current to the recorder, on and off and on again, repeatedly, until the molecular structure was altered enough to unstick the recorder for transmitting data.
但是磁带记录机却粘着了。飞行控制器应用了电流将记录机反复地打开关上，直至分子结构改变才使磁带与记录机分开。
"Miracles continued to happen on this mission," Dr. Alexander said.
“奇迹再度发生，”Claudia Alexander博士说。
Indeed, in spite of everything, scientists rate Galileo as one of the most successful missions of planetary exploration. Galileo''s eight-year orbit of Jupiter included several close encounters of each of Jupiter''s major satellites, Ganymede, Callisto, Io and Europa. No two were found to be anything alike.
确实，尽管发生了种种事故，科学家认为伽利略号是行星探索任务中最成功的一次。在伽利略号围绕着木星的八年的轨道上，它与木星的几颗主要的卫星有过好几次近距离接触，比如Ganymede, Callisto, Io and Europa。它们中没有任何两个是相同的。
Ganymede is not only the largest moon in the solar system, but it is also larger than Mercury and Pluto. Galileo discovered that Ganymede had a strong magnetic field, "something no one thought a moon would have," said Dr. Rosaly Lopes-Gautier, a member of the project''s science team.
Ganymede在太阳系中不是最大的卫星，但他要比Mercury 和冥王星大多了。伽利略号发现Ganymede还有强磁场。“这是从来没有任何人都想到卫星会有磁场，”小组的一个项目负责人Rosaly Lopes-Gautier博士说。
Icy Callisto appears to be the most heavily cratered object in the solar system. Io is bubbling with erupting volcanoes, 152 by Dr. Lopes-Gautier''s latest count. The phenomenon was discovered on previous flybys by Voyager spacecraft, but Galileo determined how plentiful and persistent the eruptions are. The lava flows are hotter than anything seen on Earth in two billion years.
冰冻的木卫四看上去像是太阳系中表面坑洞最多的一个星体。Io的火山正在爆发。据Rosaly Lopes-Gautier 博士最近的统计，至少有152个。这个现象早先就被经过的航行者号发现过，但伽利略号却更详细地展示了这些爆发是多么的壮观和持久。四处流淌的熔浆比地球在近二十亿年间的任何东西都要热。
Europa has given scientists the most reason to celebrate and speculate. In Galileo''s eight flybys, the appearance of Europa''s frozen crust suggested that it covered an immense ocean. And where there is so much liquid water, could there also be some forms of life?
木卫二是科学家们最值得庆祝和思索的。在伽利略号八次靠近中，它的冰冻的外壳暗示了它下面覆盖的广大的海洋。这么多的液态水的地方，会不会也有某些形式的生命存在呢？
That discovery sealed Galileo''s ultimate fate. If the spacecraft, after running out of maneuvering fuel, should crash into Europa, it might contaminate that moon with stowaway microbes from Earth and confound future searchers for indigenous life. So the decision was made to vaporize the spacecraft by putting it on a collision course with Jupiter.
这个发现决定了伽利略的最终命运。如果它用完燃料后坠落在木卫二上，它可能会因从地球携带的微生物污染这个星球，并会混淆以后关于这个卫星上的本土生命的研究。因此，一致决定将伽利略号的航道调整，使其与木星相撞而坠毁。
"The course is unalterable," Dr. Alexander said. "The last fuel was expended several months ago, to make sure we hit the planet."
“它的命运是无法改变的，”亚历山大博士说，“最后的燃料数月前已经被扔掉以保证它将在木星上坠毁。”
Tracking data show that the craft, traveling 30 miles a second toward the end, will crash into Jupiter on its night side. At 12:50 p.m., Pacific time, the old Galileo hands in Pasadena, hearing no radio signal, will know that their spacecraft is no more.
飞船的轨道数据显示了它以每秒3 0英里的速度撞入木星的黑面。在太平洋时间凌晨0:50分，岁月苍苍的伽利略号将失去讯号。此时，它已经坠毁了。
The stone hit the old man on the head
Imaging Radar is an imaging radar works very like a flash camera in that it provides its own light to illuminate an area on the ground and take a snapshot picture, but at radio wavelengths. A flash camera sends out a pulse of light (the flash) and records on film the light that is reflected back at it through the camera lens. Instead of a camera lens and film, a radar uses an antenna and digital computer tapes to record its images. In a radar image, one can see only the light that was reflected back towards the radar antenna.
A typical radar (RAdio Detection and Ranging) measures the strength and round-trip time of the microwave signals that are emitted by a radar antenna and reflected off a distant surface or object. The radar antenna alternately transmits and receives pulses at particular microwave wavelengths (in the range 1 cm to 1 m, which corresponds to a frequency range of about 300 MHz to 30 GHz) and polarizations (waves polarized in a single vertical or horizontal plane). For an imaging radar system, about 1500 high- power pulses per second are transmitted toward the target or imaging area, with each pulse having a pulse duration (pulse width) of typically 10-50 microseconds (us). The pulse normally covers a small band of frequencies, centered on the frequency selected for the radar. Typical bandwidths for an imaging radar are in the range 10 to 200 MHz. At the Earth's surface, the energy in the radar pulse is scattered in all directions, with some reflected back toward the antenna. Thisbackscatter returns to the radar as a weaker radar echo and is received by the antenna in a specific polarization (horizontal or vertical, not necessarily the same as the transmitted pulse). These echoes are converted to digital data and passed to a data recorder for later processing and display as an image. Given that the radar pulse travels at the speed of light, it is relatively straightforward to use the measured time for the roundtrip of a particular pulse to calculate the distance or range to the reflecting object. The chosen pulse bandwidth determines the resolution in the range (cross-track) direction. Higher bandwidth means finer resolution in this dimension.
Radar transmits a pulse Measures reflected echo (backscatter )

In the case of imaging radar, the radar moves along a flight path and the area illuminated by the radar, or footprint, is moved along the surface in a swath, building the image as it does so.
Building up a radar image using the motion of the platform
The length of the radar antenna determines the resolution in the azimuth (along-track) direction of the image: the longer the antenna, the finer the resolution in this dimension. Synthetic Aperture Radar (SAR) refers to a technique used to synthesize a very long antenna by combining signals (echoes) received by the radar as it moves along its flight track. Aperture means the opening used to collect the reflected energy that is used to form an image. In the case of a camera, this would be the shutter opening; for radar it is the antenna. A synthetic aperture is constructed by moving a real aperture or antenna through a series of positions along the flight track.
Constructing a Synthetic Aperture
As the radar moves, a pulse is transmitted at each position; the return echoes pass through the receiver and are recorded in an 'echo store.' Because the radar is moving relative to the ground, the returned echoes are Doppler-shifted (negatively as the radar approaches a target; positively as it moves away). Comparing the Doppler-shifted frequencies to a reference frequency allows many returned signals to be "focused" on a single point, effectively increasing the length of the antenna that is imaging that particular point. This focusing operation, commonly known as SAR processing, is now done digitally on fast computer systems. The trick in SAR processing is to correctly match the variation in Doppler frequency for each point in the image: this requires very precise knowledge of the relative motion between the platform and the imaged objects (which is the cause of the Doppler variation in the first place).
Synthetic aperture radar is now a mature technique used to generate radar images in which fine detail can be resolved. SARs provide unique capabilities as an imaging tool. Because they provide their own illumination (the radar pulses), they can image at any time of day or night, regardless of sun illumination. And because the radar wavelengths are much longer than those of visible or infrared light, SARs can also "see" through cloudy and dusty conditions that visible and infrared instruments cannot.
What is a radar image?
Radar images are composed of many dots, or picture elements. Each pixel (picture element) in the radar image represents the radar backscatter for that area on the ground: darker areas in the image represent low backscatter, brighter areas represent high backscatter. Bright features mean that a large fraction of the radar energy was reflected back to the radar, while dark features imply that very little energy was reflected. Backscatter for a target area at a particular wavelength will vary for a variety of conditions: size of the scatterers in the target area, moisture content of the target area, polarization of the pulses, and observation angles. Backscatter will also differ when different wavelengths are used.
Scientists measure backscatter, also known as radar cross section, in units of area (such as square meters). The backscatter is often related to the size of an object, with objects approximately the size of the wavelength (or larger) appearing bright (i.e. rough) and objects smaller than the wavelength appearing dark (i.e. smooth). Radar scientists typically use a measure of backscatter called normalized radar cross section, which is independent of the image resolution or pixel size. Normalized radar cross section (sigma0.) is measured in decibels (dB). Typical values of sigma0. for natural surfaces range from +5dB (very bright) to -40dB (very dark).
A useful rule-of-thumb in analyzing radar images is that the higher or brighter the backscatter on the image, the rougher the surface being imaged. Flat surfaces that reflect little or no microwave energy back towards the radar will always appear dark in radar images. Vegetation is usually moderately rough on the scale of most radar wavelengths and appears as grey or light grey in a radar image. Surfaces inclined towards the radar will have a stronger backscatter than surfaces which slope away from the radar and will tend to appear brighter in a radar image. Some areas not illuminated by the radar, like the back slope of mountains, are in shadow, and will appear dark. When city streets or buildings are lined up in such a way that the incoming radar pulses are able to bounce off the streets and then bounce again off the buildings (called a double- bounce) and directly back towards the radar they appear very bright (white) in radar images. Roads and freeways are flat surfaces so appear dark. Buildings which do not line up so that the radar pulses are reflected straight back will appear light grey, like very rough surfaces.
Imaging different types of surface with radar
Backscatter is also sensitive to the target's electrical properties, including water content. Wetter objects will appear bright, and drier targets will appear dark. The exception to this is a smooth body of water, which will act as a flat surface and reflect incoming pulses away from a target; these bodies will appear dark.
Backscatter will also vary depending on the use of different polarization. Some SARs can transmit pulses in either horizontal (H) or vertical (V) polarization and receive in either H or V, with the resultant combinations of HH (Horizontal transmit, Horizontal receive), VV, HV, or VH. Additionally, some SARs can measure the phase of the incoming pulse (one wavelength = 2pi in phase) and therefore measure the phase difference (in degrees) in the return of the HH and VV signals. This difference can be thought of as a difference in the roundtrip times of HH and VV signals and is frequently the result of structural characteristics of the scatterers. These SARs can also measure the correlation coefficient for the HH and VV returns, which can be considered as a measure of how alike (between 0/not alike and 1/alike) the HH and VV scatterers are.
Different observations angles also affect backscatter. Track angle will affect backscatter from very linear features: urban areas, fences, rows of crops, ocean waves, fault lines. The angle of the radar wave at the Earth's surface (called the incidence angle) will also cause a variation in the backscatter: low incidence angles (perpendicular to the surface) will result in high backscatter; backscatter will decrease with increasing incidence angles.
Radar backscatter is a function of incidence angle, (theta)i
NASA/JPL's Radar Program
NASA/JPL's radar program began with the SEASAT synthetic aperture radar (SAR) in 1978. SEASAT was a single frequency (L-band with lambda ~ 24 cm or 9.4 inches), single polarization, fixed-look angle radar. The Shuttle Imaging Radar-A (SIR-A), flown on the Space Shuttle in 1981, was also an L- band radar with a fixed look angle. SIR-B (1984) added a multi-look angle capability to the L-band, single polarization radar. SIR-C/X-SAR is a joint venture of NASA, the German Space Agency (DARA), and the Italian Space Agency (ASI). SIR-C/X-SAR provided increased capability over Seasat, SIR-A, and SIR-B by acquiring images at three microwave wavelengths (lambda), L- band (lambda ~ 24 cm or 9.4 inches) quad-polarization; C-band (lambda ~ 6 cm or 2.4 inches) quad- polarization; and X-band (lambda ~ 3 cm) with VV polarization. SIR-C/X-SAR also has a variable look angle, and can image at incidence angles between 20 and 65 degrees. SIR-C/X-SAR flew on the shuttle in April and in October of 1994, providing radar data for two seasons. Typical image sizes for SIR-C data products are 50kmx100km, with resolution between10 and 25 meters in both dimensions.
Parallel to the development of spaceborne imaging radars, NASA/JPL have built and operated a series of airborne imaging radar systems. NASA/JPL currently maintain and operate an airborne SAR system, known as AIRSAR/TOPSAR, which flies on a NASA DC-8 jet. In one mode of operation, this system is capable of simultaneously collecting all four polarizations (HH,HV, VH and VV) for three frequencies: L- band (lambda ~ 24 cm); C-band (lambda ~ 6 cm) ; and P-band (lambda ~ 68 cm). In another mode of operation, the AIRSAR/TOPSAR system collects all four polarizations (HH,HV, VH and VV) for two frequencies: L- band (lambda ~ 24 cm); and P-band (lambda ~ 68 cm), while operating as an interferometer at C-band to simultaneously generate topographic height data. AIRSAR/TOPSAR also has an along-track interferometer mode which is used to measure current speeds. Typical image sizes for AIRSAR/TOPSAR products are 12kmx12km, with 10 meter resolution in both dimensions. Topographic map products generated by the TOPSAR system have been shown to have a height accuracy of1 m in relatively flat areas, and 5 m height accuracy in mountainous areas.
JPL are studying designs for a free-flying multi- parameter imaging radar system like the one flown during the SIR-C/X-SAR missions. JPL are also studying a global mapping mission (TOPSAT) which will use radar interferometry to generate high quality topographic maps over the whole world and monitor changes in topography in areas prone to earthquakes and volcanic activity.

很快的，一天快要结束，我也该回地球了，月球人纷纷来和我握手惜别，嫦娥与玉兔差点掉了泪?
我在月球上的一天
在地球这个大千世界里，我过的已经厌倦了。钱很多，再存下去也不是个办法，连银行都说内存不够大。听说最近流行月球探险，我便从银行里取出2000万美金，开始我的月球之旅。
“月球之旅”这一娱乐项目是中国人研制开发的，我在航天技术人员的协助和紧张的训练后进入了太空舱，由神舟X号把我送上月球，整个飞船中只有我一个（这是我额外提出的要求）。
我的行动由无线电作指导，在月球上的行程由卫星监控。我必须时时刻刻与地球保持联系，即便是我迷失方向，也会顺利抵达人类的地球。
好大的月球，我们都知道，月球表面是凹凸不平的，黑黑的一大片让人感到很单调，很无聊，只想发脾气，看到脚下有一块不大不小的石头，一怒之下就一脚踢开，由于在月球上失重，我被自己的力掀翻，头朝地，头上戴的仪器被砸坏了，幸亏安全措施好，我没有受伤，可以继续前进，可是与地面无法联系，信号中断，仪器失灵。我害怕，恐慌，想到自己的未来应该有美好的生活，我不愿就这样无声无息白白死在月球上。
我想寻找能帮助我在月球上生存下来的物品。走了漫长的一段时间之后，我发现有一个小孔，发出怪异的亮光，如果不仔细看还发现不了。我兴奋地走过去，用手砸了一下洞口，向里吹了一口气，还是没反应，往里面看却什么也看不见。这让我很迷茫，就拿了一块石头把洞口死死地堵住，可是过了一会，石头像火箭一样喷发出来，接着就冒出一阵烟气，烟气变成一个老头，我很好奇，就上去问他，他拿着一个类似地球上铁锨一样的东西，使劲地敲打着地面。我很有礼貌地问他是做什么的，他说他是月球锅炉房的主任。我问他能否帮我生存下去，他看见像我这样的陌生面孔，就热情地带我去参观属于他们的世界。
当然，他首先带我去看的是锅炉房，我此时的心情可谓是好奇之极，随他进入他的领域。走进之后才知道，他与地球不同，燃烧出的火焰是七彩斑斓的，不同颜色的火焰有不同的用处，锅炉上面有无数的小孔，不同颜色的火焰会被吸入不同的小孔，完成他们的使命。接着老人讲述了月球的底部分为三个层部：第一兽物层，第二克隆层，第三是中央首脑层。
我的奇异旅程从此开始了。我在老者的引导下，走入了第一层，即兽物层，也可以叫军事防御层，何谓兽物层？这里全是叫不出名字、无规则形状可以形容的怪异大体形动物，他们的攻击力极强，以强壮的躯体与敌人火拼。还有多足兽，全身软软的叫人看了就恶心，他们喷出绿色的毒汁，腐蚀敌人。向地上看，可以看到一条血河，有很多支流，这里的生物全靠吸血为生。一只三头五牙狗向我冲来，嘴上沾满鲜血，十分强悍，它是这里的头领，以其奔跑速度著名。它看见锅炉爷爷便十分温顺，看着我这位“外星人”不停地摇尾巴。
随后进入第二层———克隆层，这里的人长得和地球人一模一样，不过他们在说话时嘴里会喷出火焰，因为他们的鼻子需要大量的热量才能呼吸，不然就会紧缩在一起，窒息而死。那些生物就是他们精心研制的，而他们吃的是液态或固态的化学物质，如硫单质、铁溶液等。可见月球上的矿物资源是他们最好的食品。
接着，第三层是中央首脑层，他们不是生物，而是靠月球内部某种未知元素作能源的一套完整的制造克隆人并控制他们的机器，机器发出各种各样的光环，一个个克隆人的生长过程清晰可见。原来，整个月球的命脉就在这里。我由老人带领，饱餐了一顿近似地球人食用的食品。
突然间月球防御灯响了，全场一阵骚动，我知道一定是地球人来接我了，我匆忙告别，返回太空舱，启动机器，临别时那位老者告诉我，你遇到的事和所看到的一切请不要告诉其他人，免得人类来得太多破坏我们的环境和我们宁静的生活。在返回的途中我想，我一定要再次返回月球，探索这里不为人知的秘密。
我在月球上的一天
“弯弯的月儿小小的船，小小的船儿两头尖。”不远处树荫下纳凉的儿童轻轻哼唱着，望着头顶上的明月，不禁勾起了我无穷的幻想和思绪。
“这里是什么地方？有没有人啊？”只见脚下踩着一片灰褐色的土地，周围“峰峦叠嶂”全被笼罩了一层神秘的黑色面纱，四周安静得可怕，没有任何生机。就在我感到毛骨悚然，马上就要哭出来的时候，突然传来了一个女人的声音：“欢迎你，小朋友，欢迎你到我的星球作客！”那声音是那么悦耳动听，一霎时把我吸引住了，闻声望去，竟是一个飘飘欲飞的仙女，那婀娜的身姿，美丽的脸庞，可以称得上倾国倾城，难道她就是嫦娥？这儿就是月球？！“是的，这里是月球，我是嫦娥。”她居然有心灵感应，一下就猜出了我的心思。我的天啊！我顿时感到晴天霹雳，亲爱的爸爸妈妈，我再也见不到你们了。心里想着，不由得哭起来。“小妹妹，不用怕，一天之后你便能再见到你的父母，今天你作为地球上所有生灵的代表，来随我参观一下你们未来的家园吧！”“未来的家园？”嫦娥姐姐见我一脸茫然，忙给我解释，原来，在人类无休止地破坏地球之后，竟想移居月球！
说着，我便跟她来到了一座乌黑的高大山峰面前，“这是祖冲之环形山。”她说，“祖冲之是中国古代的天文学家，对吧？”“嗯！”我肯定地点点头，不禁对嫦娥的渊博的知识感到佩服。不知又走了多久，我们的眼前突然出现了一座气派的豪华宫殿，屋门的上空方正地悬挂着一块牌匾，上面刻着“广寒宫”三个金文大字，在黑暗的衬托下更加耀眼。来到广寒宫，嫦娥做的月饼令我垂涎三尺。正当我津津有味地品尝月饼时，突然房屋剧烈地颤动起来。“陨石撞击月球啦！”是正在砍桂花树的吴刚大哥在喊叫，我闻声望去，不觉大惊失色，几百个如巨石般的流星正向月球袭来，锋利的棱角和气层摩擦出耀眼的火花，燃烧着，把广寒宫都砸了个大窟窿。逃跑吧，可月球上空空如也，没有任何逃亡机器，难道就只能坐以待毙吗？正在千钧一发之际，嫦娥姐姐把手指一挥，陨石都定在了空中，是她用仙术救了我们，好不容易躲过了一场灾祸！
在月球上的一天，可真令人难忘。我想我们应该反省自身该爱护地球了，别想着移民月球，要知道，地球才是我们的真正的家！
我在月球上的一天

Then, I feel that the first ship body weight, and three or four metres high JianBuRuFei obstacles and 10 meters deep ditch, can leap over. Walk on the moon, I always feel the walking forward unhurriedly suddenly, a beauty appeared before me. "Hi, How do you do? What \ 's your name?" "Oh, My name" e, chang this?

"Hello" after a while, outside gongs and drums voice echoes, I felt curious: "miss the goddess, outside doing?" "I tell you, we will be the annual lunar throw stones ceremony." So, it hadn't heard said, "throw stones rites". The goddess of the mind that I like, I decided to take to go to. At the destination, and the people here are surprisingly, everyone was wearing a thin dress, they are afraid of pain? And these stone in your body is not painful. The no-road, ceremony begins. Everyone you throw me, I throw you immersed in the fuss atmosphere, happy, and happy!
Soon, the end is near, I also one day the earth, moon back to shake hands with my people, the moon and the bid was dropped tears......
I on the moon
In the whole world, I've already got tired. Money, save down is not the answer, the bank said memory is not big enough. The recent exploration, that I will remove from the bank $20 million, started my trip to the moon.
"A trip to the moon is the Chinese entertainment items, I developed in space technology personnel training to assist and nervous after capsule entered by the shenzhou X number, the spacecraft on the moon, I only me a (this is my additional request).
My actions by radio guide, on the moon by satellite monitoring schedule. I must keep in touch with gladness fill the earth, even I lost, will arrive human earth.
A moon, as we all know, the surface of the moon is uneven, with a large make people feel very dull and boring, just to see a bad temper and feet of stone, anger is a foot kicks, because on the moon, I was lost his head toward the ground forces, over his head, wear instruments were broken, thanks to safety measures, I was not injured, can continue to advance, but not with the ground, instruments, signal. I am afraid of panic, and his future should have the good life, I don't want to throw it quietly died on the moon.
I want to seek help I can survive on the moon. Gone a long time after that, I found a strange light holes, if you don't watch carefully, cannot find it. I walked to a hit, with his hand in the hole, to blow, or didn't respond to look inside, but could see nothing. It makes me very confused, took a stone, but the hole will block after a while, a stone, then burst out of a gas, from gas to become a man, I'm curious, just go ask him, he took a similar things on earth, as well as shovel muscled knocking at the ground. I politely asked what he is, he said he is the director of the boiler. I asked whether he can help me to survive, he saw the unfamiliar faces like me, enthusiasm, I visit their area of the world.
And, of course, he's taking me to see the boiler, my mind now is very curious, he entered his field. Then he walked with the earth, and the flame burning out different shape is brilliant, different colors of the flame has different, with numerous small boiler, different colors of the flame will be inhaled different holes, their mission. Then the man tells the bottom is divided into three parts: the first thing layer, the second beast, the third is the cloning of leaders.
My journey starts a strange. In my elder, into the first layer, namely beast, can also call things layer is beast, military defenses thing layer? Here is a name that no, no rules of strange shape can describe large animals, they fit to attack the body and go into too many duels into enemy and strong. Are there any more, all soft call foot beasts who is sick, they looked out of the green, corrosion DuZhi enemy. To see, you can see a blood river, there are many tributaries, here all by biting living creatures. A three to five teeth, I rushed to dogs, very tough talk with blood, and it is the chief, with its running speed. It is very gentle and saw the boiler grandpa, I kept the "alien" wave tail.
Then entered the second -- cloning layer, the people here long and the earth like a man, but their mouth will speak out in the flame, because they need a lot of heat can nose breath, otherwise will tighten together, choke to death. Who is that they have developed organisms, and they ate liquid or solid chemicals, such as sulfur esterification, iron solution, etc. Visible on the moon is the best of their mineral resources.
Then, the third is the central summit layer, they are not on the moon, but for some unknown elements within a complete set of energy and control of their clone manufacturing machines and machine, a variety of one of the clone aura process clearly visible. Originally, the moon's lifeblood is here. I led by the old man had a good meal, the approximation of food.
Suddenly the lights, ringing defence uproar, I know who is the earth to meet me, I hurried goodbye, return capsule, start machine, parting the man told me that you see things and meet all the others, so please don't tell us much more human environment and our peaceful life. In return, I think, on the way back to the moon again, I must explore here, the secret of unknown.
I on the moon
"The curved moon, small vessel two small boats." The children not heat the shade, looking humming gently on the head of the moon, and reminded me endless illusion and thoughts.
"What place is it? Any?" Only on the land, a beige around "natural" are all the peaks of the mysterious veil layer of black, quiet, no vitality. When I felt creepy, will cry out, when suddenly came a woman's voice: "welcome, children, welcome you to visit my planet!" The voice is so beautiful, the moment I absorbed, smell, it was a reputation to fly fairy waved, the graceful form, beautiful face, which is the goddess QingGuoQingCheng, don't she? Here is the moon? ! "Yes, here is the goddess of the moon, I am." She has a telepathic, guess out of my mind. My goodness! I suddenly felt a thunderbolt, dear mom and dad, I never see you again. Pondering, help crying. "My little sister, don't be afraid, one day after you can see your parents, today you as representatives of all creatures on earth, with my visit to your future home!" "The future home?" The elder sister, I saw a busy to explain to me, in humans, damage the earth after endlessly, want to move to the moon.
Then I said, with her to a dark before the mountains, "the tall ZuChongZhi is ringed." She said, "ZuChongZhi is ancient Chinese astronomer, right?" "Yes!" I'm sure of the goddess nodded, the profound knowledge. Not long after, our eyes suddenly appeared a magnificent palace, the luxury of door to the square piece, hanging signboard carved AnHanGong ", "three character in the darkness of them against more brightly. Come, the goddess of mooncakes AnHanGong do my services. While I tasted mooncakes with relish when suddenly it wobbles violently houses. "Meteorites colliding with the moon!" Is the WuGang GuiHuaShu cut out, my brother in popularity to smell, it was surprised and hundreds of such as stones of the moon, sharp shooting positive hit the edges and gas friction but, burning, all messed up a big AnHanGong hole. Flee, the moon is empty, no escape machine, don't just do besides? It is the sister of a finger in the meteorite all, she is in the air, with magic saved us, to avoid a disaster!
On the moon, but really unforgettable day. I think we should reflect on their love the earth, moon don't, as you know, the earth is our home.
