Scientists agree that about 4 billion years ago, a heavy meteor shell bombarded us with deep cracks and craters in its shell. These and similar effects led to the formation of large cleft nets beneath the moon surface, but also to an increase in the number of pores on the surface.
The researchers at MIT searched for traces of small asteroid strikes, especially in areas other than the smooth springs that the moon formed by fragmenting the heavy bombardment. Researchers think that near these small craters, there is a reduction in the number of pores in the soil that is removed from the surface.
He saw that the layer of what scientists called the ‘ megaregolith ‘ was at the top of the shell. This layer is covered by craters with a diameter of 30 kilometers or less. On the contrary, it was seen that the larger craters were not able to affect the depth of the shell. Larger craters are less fractured and less porous around the periphery.
Jason Soderblom of MIT: “The pores in the planetary crust are of great importance in understanding how all the water in the surface has landed underground. We think that the life on Earth has evolved a little underground. This is the primary reason for the formation of large underground pockets and spaces. The moon is giving us a sense of how this process is going. ”
During the study, about 1,200 crater mass shots accounted for in the oldest and abundant cratered areas of the Moon, with NASA’s GRAIL ordinance given. Masses of the crater and its surroundings were compared.
