USA. Scientists have created a new moon model. They came to important conclusions
The research was written in mid -May in the scientific letter « Nature ». Gravitational data to carry out this project was obtained by a space probe as part of the NASA Grail mission. It turns out that the closer side of the moon is covered with plains, and the next page is more uneven. « A comprehensive test of lunar gravity using data obtained by two robotic space ships provides new tips on why two sides of the moon – one always turned towards the earth, and the other always reversed – they look so different » – wrote Reuters.
New moon model. We know why he has two different sides
The agency states that the data from the Grail (Gravity Recovery and Interior Laboratory) mission of the American Space Agency indicate that The deep interior of the moon has an asymmetrical structure, apparently caused by intensive volcanism on its close bank billion years ago, which helped shape the features of its surface.

Scientists have found that the closer side of the moon bends a bit more than further during its elliptical orbit around the earth thanks to the influence of the gravitational of our planet. This process is called tidal deformation. This indicates the differences in both sides of the inside of the moon, specifically in the geological layer called the coat.
Scientists about new information about the moon
Our study shows that the interior of the moon is not uniform: the side turns towards the ground – the side is close – it is warmer and geologically more active in the background than the far side. The closer and rest of the moon look completely different, as indicated by the differences in topography, the thickness of the shell and the number of heat producing elements
– said Ryan Park, manager of Solar System Dynamics Group at NASA Jet Propulsion Laboratory in California and the main author of the study published in the journal Nature.
The close side of the moon is covered with extensive plains, called mare, created from a molten rock, which cooled down and solidified billions of years ago. Its other side has a much more uneven area, with several plains.
Reuters emphasizes that some scientists have hypothesized that intense volcanism nearby, which caused radioactive accumulation, generating the heat of elements on this side of the coat, caused the differences in the surface observed today. New discoveries provide the strongest evidence so far to support this thesis.
Very important research on the moon
Scientists have spent years analyzing data from the Grail EBB and Flow probe, which circulated around the moon from December 2011 to December 2012.
Our study provides the most detailed and accurate gravitational map of the moon so far. This improved gravitational map is the basis for the development of lunar positioning, navigation and time measuring systems (PNT), which are necessary for the success of the future mission to explore the moon. By improving our understanding of the moon’s gravitational field, it contributes to the establishment of a precise lunar reference frame and time system, enabling safer and less unreliable navigation for spacecraft and surface operations
– says the park, quoted by Reuters.
Scientists have found that the same approach used here, using gravitational data to assess the interior of the moon, can be applied to other bodies in the solar system, such as the moon of Saturn Enceladus and the moon of Jupiter Ganimedes, taken into account in search of potential life outside the earth.
