Part One: Moon Sea

Observing the moon from the earth, some places on the moon are slightly darker than the surrounding areas. These darker regions are called "lunar maria".

The name "lunar sea" was first proposed by the Italian scientist Galileo Galilei in the early 17th century. Because the telescope he used was very crude, these darker places on the moon looked like seas on the Earth, so he called them lunar maria.

PPT on the secrets of exploring the moon, part 2: basic common sense about the lunar surface

Basic knowledge about the lunar surface

The average distance between the moon and the earth is about 380,000 kilometers. The volume of the moon is only 1.49 of the volume of the earth. The moon's attraction to objects on its surface is only 1�6 of the earth's gravity.

There is no air or water on the moon, and no life has been found so far. The moon's surface has plains and numerous craters. The moon's surface is covered with a layer of porous volcanic ash soil, which is only more than 30 centimeters thick in some places, but several meters thick in other places, or even thicker.

On the moon, the temperature on the side facing the sun can reach 130°C; the temperature on the side facing away from the sun can reach as low as –180°C.

If you were asked to choose where to land on the moon, how would you choose?
