A trip to the moon painted handwritten newspaper

In AD 1969, Apollo 1 1 manned the moon, and 600 million people all over the world watched this historic scene on TV at the same time. When American astronaut Armstrong left the first human footprint on the moon, the audience were fascinated. We conquered the moon, which human beings have worshipped for millions of years. This small step on the moon seems to imply the infinite future of mankind!

Four purposes of lunar exploration: handwritten newspaper materials

Firstly, the three-dimensional image of the lunar surface is obtained, so that the basic geomorphology and structural units of the lunar surface are divided, and the outline map of the lunar geology and structure is preliminarily drawn up, which provides reference for the optimization of the subsequent soft landing area. At present, there is no image covering the entire surface of the moon in the world; If China can get three-dimensional images of the whole moon, it will be of great significance to better understand the geological structure and evolution history of the moon. China will strive to make these images more complete and detailed than those already available abroad.

The second is to analyze the content of useful elements on the lunar surface and the distribution characteristics of material types, that is, to detect useful elements on the lunar surface and initially compile the distribution map of each element on the lunar surface. The United States has made a global distribution and content of five useful elements, and Chang 'e 1 will detect the distribution characteristics and laws of four important elements on the surface of the moon that may have development and utilization prospects.

The third is to detect the characteristics of lunar soil. China will carry out microwave radiation detection on the lunar surface for the first time, obtain the monthly distribution characteristics of lunar soil thickness, study the age and evolution of the lunar surface, and estimate the distribution and resources of helium 3 in lunar soil. At present, there are more than 100 kinds of minerals known on the moon, five of which are not found on the earth. Especially helium 3. It is a safe, efficient and clean new nuclear fusion fuel, which can change the energy structure of human society, but it is very rare on earth. Every 100 ton of helium-3 raw material can meet the global power supply for one year, and the reserve of helium-3 on the moon is estimated to be 5 million tons, which can meet the power supply demand of human beings for more than 10000 years. Each gram of gold is worth 1 1 USD, while each gram of helium 3 is worth $400. The development and utilization prospect of the moon's potential mineral resources and energy has become the most important driving force for major space countries to return to the moon and carry out lunar exploration.

The fourth is to detect the space environment of the Earth and the Moon, which will record the original solar wind data and study the influence of solar activities on the space environment of the Earth and the Moon.

The first three tasks mentioned above have not been carried out abroad, and the fourth task is that China has obtained space environment data outside the geostationary orbit for the first time.
