Scientists from Russia show that samples were taken from the other side at a depth of 15 meters to determine the date on which one side of the moon is visible from the ground.
"We are working on the design of a new generation of drilling machines that will be able to take soil samples at a depth of 15 meters," said Yevgeny Sliota, Director of the Laboratory for Geological and Analytical Chemistry for the Moon and other planets of the Russian Academy of Sciences in an interview for Novosti. "If we use this machine to take samples from the surface of the back of the moon, we will find out when the moon rotates around its axis and around the earth, and one side is visible from the ground."
As proposed by Seliot, a network of 8-10 automatic seismic stations should be introduced into the moon. "These automatic stations are in the form of a 50 kg container that have instruments for measuring the power of earthquakes, magnetic fields and gravity, and a probe for measuring electromagnetic properties and depth of temperature. 5 meters and angle reflector for laser navigation.
China became the first country in history to send the probe to the last part of the moon and landed on a precise location on 3 January 2019.
