ИСТИНА

The moon is the only object, except for the Earth, where seismic methods have been successfully applied, giving the most complete and objective information in the study of its internal structure. The first lunar seismometer was installed on July 20, 1969 in the Sea of Tranquility on the visible side of the moon during the Apollo 11 expedition. He fed on solar panels and kept seismic recording only during the day. In the period from November 1969 to December 1972, on the visible side of the moon, a network of four homogeneous automatic seismic stations was created that feed on isotopic power plants designed for 10 years of continuous operation. Apollo seismometers continued to operate for eight years, during which they transmitted information on the natural seismic activity of the moon, and the structure of the lunar crust and upper mantle . However, the deep bowels of the moon remained not accessible to the Apollo seismic network. Since seismic stations were located within a small area on the lunar surface, such a network was not able to effectively record moonquakes occurring at arbitrary points in the bowels of the moon. Here, optimal configurations of seismic station networks are considered, which make it possible to effectively register moonquakes, which should be implemented in future seismic experiments on the Moon and other planets of the earth group.
