The force of the magnetic field of the moon could increase about 2.8 billion years ago.
According to Chinadaily.com, this conclusion was brought to a team of scientists under the leadership of Tsu Rishiang and CEA ShUHUI from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (CAS) and the National Astronomical Observatory.
fundamentally new information about the evolution of the magnetic field of the lunar body made it possible to obtain breed samples collected from the reverse side of the moon by the Chinese moon probe “Chan-6”. In particular, Chinese scientists have studied a piece of basalt breed a size of 4 millimeters.
Analysis of the samples published on Thursday in Nature magazine, indicates an unexpected revival of the Magnetic Field of the Moon 2.8 billion years ago after a sharp recession about 3.1 billion years ago.
This discovery questions the prevailing theory that the lunar Dynamo remained in a low -energy state after this decline.
previous studies of lunar samples showed that the magnetic field of the moon similar to the earth about 4.2-3.5 billion years ago experienced two sharp recessions and stopped about 1 billion years ago.
The moon also had a magnetic field similar to the earth in the past
On the moon once there was a layer that created a magnetic field similar to the earth, Tsai Shuhway said. “The magnetic field is an important element in maintaining the inhabitable environment of the planet. It not only protects against cosmic rays, but also protects the atmosphere and water. This makes it an important factor in creating a suitable environment for the development of life,” the scientist explained.
According to him, an understanding of the evolution of the magnetic field generator of the moon is of great importance for identifying the internal structure of the moon, its thermal history and the surface environment.
“Having discovered and comparing these factors that make the magnetic fields of the moon and lands different, we will be able to better understand the processes of the development of magnetic fields of different planets and get important information for future land and humanity,” he added.
Moon missions of China
The National Cosmic Administration of China (CNSA) and the Federal Space Agency of Russia (Roscosmos) implement a project to create a scientific station on the moon for research.
In 2020, the Chane-5 Returned Capsule, containing two kilograms of lunar soil, has successfully landed in the Chinese region inner Mongolia. Now China has become the third country in the world that has mined the sample of the lunar soil and delivered it to the ground.
The next lunar mission of China, Chany-6, became the first research mission, during which samples of rocks and soil were collected on the dark side of the moon.
The Chinese manned space agency (CMSA) announced in July 2023 that it intends to send people to the Moon by 2030.
