On this day 64 years ago, on November 27, 1961 (October 20, 1961 lunar calendar), the Soviet Union made the world's first lunar instrument. Lunar Globe November 27, 1961 - The Soviet Union made the world's first lunar instrument. The lunar instrument recorded the distribution of land and sea on the moon, as well as mountains, rivers, lakes and marshes. Although there is no water on the moon, these terms have been used for a long time, with only symbolic significance. Since the Italian astronomer Galileo Galilei observed the moon with a telescope in 1610, various features on the moon have been gradually discovered, so the names of people and places began to appear on the moon. For nearly 400 years, the moon has become a "small earth" filled with the names of people and places on the earth. Now, according to the international unified naming, the lunar instrument is made according to these naming and diagrams. Like the maps and place names printed on the globe, it is well-founded. We also design and print the lunar instrument according to the internationally shared scientific information, which is accurate and correct. Due to different needs, the lunar instrument we make also has various specifications. The names and graphics on the small lunar instrument are less, but still accurate. The names and graphics on the large lunar instrument are more. The lunar instrument is made according to the internationally published lunar surface structure and longitude and latitude coordinates and related names. It is a miniature of the moon. From the lunar instrument, various structures on the lunar surface can be viewed, especially craters and mountains, the distribution of "seas", "oceans", "lakes" and "marshes" and their respective names. More important to us is the front of the moon, because this is the area where we can see with the naked eye, observe and take pictures with telescopes. The far side of the moon cannot be seen by us, but it has reference value. Since we live on the earth, we need to understand the seasonal division of the earth throughout the year and the motion of rotation and revolution, so the globe is mounted on a seat that tilts itself. But the lunar instrument does not have this need. It can be placed at will, mainly to know the positions and names of various points on the lunar surface. The points on the moon are also expressed in longitude and latitude, which is the same as the globe. We use thicker lines and instructions on the lunar instrument to distinguish the front and back of the moon, which cannot be confused. In addition, all those with Chinese names on the lunar instrument (all ancient and modern scientists) are printed in red. On the front of the moon, there is a Chinese person named Gao Pingzi; on the back, there are Chinese people: Zhang Heng, Zu Chongzhi, Guo Shoujing, Shi Shen, etc. In addition, the landing sites of the Apollo spacecraft that have landed on the moon are also named by markers. When China's Chang'e lunar exploration project began, we could use the lunar instrument to learn about various features, names, and locations on the lunar surface. It will enable us to understand the situation with the lunar instrument when we hear news of lunar exploration without being at a loss. Comments: Lunar instrument for teaching is similar to a globe
