role of the moon

This hemisphere was hidden from human view until the Soviet automatic probe Luna 3 photographed it for the first time on October 7, 1959.[1] Since the Moon takes the same time to go around itself as it does around the Earth, it always has the same face visible from the Earth. This is because the Earth, by an effect called gravitational gradient, has completely slowed down the Moon. Most of the regular satellites present this phenomenon with respect to their planets.

In the programs for the establishment of a stable lunar base, it has been planned to use the occulted hemisphere for the installation of observation instruments for the study of the firmament, since that is more protected from the influence of the Earth than the visible hemisphere.

On December 7, 2018, China launched the Chang’e 4 probe to explore the hidden side of the Moon for the first time in history.[2] This probe succeeded in landing on the moon on January 3, 2019 and is intended, among other things, to study low radio frequencies, tomato cultivation on other planets and mineral resources.[3] The probe was launched on January 3, 2019.

For a long time the fundamental problem concerning lunar history was that of its origin. The hypotheses that have been elaborated in this respect are as varied as they are different from each other. The most important hypotheses are:

The lunar landscape is characterized by the presence of impact craters, the material ejected by these, some volcanoes, depressions filled by the magma ocean, hills and the marks left by lava flows.

The highlands have the largest number of impact craters from a diameter of about one meter up to 1000 kilometers. Before any robotic mission could reach the Moon, scientists thought that the origin of some of these craters was volcanic, an idea that changed radically with the return of lunar soil and rock samples with the Apollo missions clearly showing the important role of the impact process in the formation of the terrain.

Impacts occur at speeds approaching 20 km/s (70 000 km/h). On each impact high pressure waves bounce off the projectile and the impacted body, a process in which the projectile (a meteorite) is destroyed by the passage of the shock wave causing it to evaporate almost entirely. The material of the impacted body is strongly compressed and briefly decompressed afterwards. A portion of this material is evaporated and another part is melted, but most of it (a mass 10 000 times greater than that of the meteorite) is ejected out of the crater forming the surrounding ring. The central part of the crater is a more depressed area than the rest of the terrain.
