A plane map mapped and compiled on the basis of studying the spherical apparent positions of various features on the moon surface
The lunar chart is studyingMoonA plan that is mapped and compiled based on the spherical apparent position of various surface features.In the early days, the lunar surface was mapped bytelescopeThey were copied and later surveyed by photography.The first study of the lunar surface structure isGalileoIn 1610, he found that the moon surface was full of valleys with a self-made telescope that could magnify more than 30 times. He was the first to draw a picture of the moon surface.The mapping of the lunar surface map is of practical significance for lunar navigation, and the research on the origin and evolution of the moon is also very important.
In the middle of the seventeenth centuryHervilleAfter ten years of hard observation, a detailed lunar surface map was drawn.He measured the height of the lunar peak more accurately than Galileo.The name o of various features marked on the lunar surface map by Riccioli is still in use today.In the 18th and 19th centuries, Mayer, Schrother, Bell, Medler, J. Schmidt, Lorman and others carried out a large number of observations, which made this work get great development.Since the 20th century, wilkins, moore and others have precisely measured the position of about 5000 points on the lunar surface by photographic methods.The diameter of the French Rizhongfeng Observatory is 60 cmRefracting telescopeA lunar surface map with a scale of 1: 1, 000, 000 has been prepared.In the 350 years since Galileo started his work on lunar maps, he has successively published as many as 150 lunar maps.The largest diameter is 7.5 meters.Since the moon always faces the earth with the same face, the back of the moon has always been an inextricable mystery. In 1959, the Soviet Union's "Moon" 1 probe took the first picture of the back of the moon, filling this gap, and followed by a series ofLunar probeAnd spacecraft, such as Luna, Wanderer, Lunar Surveyor"Lunar Orbit Circulator"As well as the manned "Apollo", a large number of photos of the moon were obtained.There are four craters on the back of the moon named after ancient Chinese astronomers: Shishen craters, Zhangheng craters, Zuchongzhi craters, Guo Shoujing craters. In addition, there is another one named after the ancient Chinese official position "Wanhu".According to 1973International Astronomical UnionThe discussion of the 17th group of the "Moon" Professional Committee of the 15th Congress was published by the National Aeronautics and Space Administration of the United States, namely, the Lunar Aeronautical Map and the Topographic Ortho Projection Map of the Moon.The former will be considered according to warp and weft?Di Zhi?44 regions, printed on a scale of 1: 1, 000, 000.The latter subdivides each of the 144 regions into 16 units, which are published at the scale of 1: 250000, with a total of 2, 304 sheets.

The ancient people tens of thousands of years ago were still in the primitive era of drilling wood to make fire and tying ropes to record things. They should not have touched the breath of civilization;But the discovery of archaeologists in an ancient cave made us start to look at these old ancestors again.They left the most complete lunar surface rock paintings in the cave, whose richness and detail can only be matched in the era after the invention of the telescope.Archaeologists can only prove that the lunar surface is ancient without doubt, and we can boldly ask: If the lunar surface was not painted by the human ancestors tens of thousands of years ago, who would be the real painter behind it?
