What we discovered on the far side of the moon

sEven months after launch, US robotic rover Perseverance landed successfully On Mars on February 18. was part of the landing mission March2020 and watched live by millions of people around the world, reflecting a renewed global interest in space exploration. soon after that of China Tianwen-1, an interplanetary Mars mission consisting of an orbiter, lander and rover, called jharong,

Perseverance And jharong These were the fifth and sixth planetary rovers deployed in the past decade. America’s first Curiosity who landed on Mars in 2012, after of china three Change Missions,

In 2019, Chang’e-4 lander and its Yutu-2 Nomad The first human objects to land were on the far side of the Moon – the side that is farthest from Earth. This is an important milestone, which has equal importance Apollo 8 Mission In 1968, when humans first saw the far side of the moon.


To analyze the data captured from Yutu-2 rover, which used ground penetrating radar (GPR), we developed a tool Which can explore the layers beneath the Moon’s surface in greater detail than ever before. It was also able to provide insight into how it evolved.

The far side of the Moon is of great importance due to interesting geological formations but this hidden side also blocks all electromagnetic noise from human activity, making it an ideal location for construction. radio telescope,

Orbiter radar has been used for planetary science since the early 2000s, but until recently the Chinese and US rover missions were the first to use GPR at the site. This GPR is now ready to be part of the scientific payload of future planetary missions, where it will be used to map the subsurface of landing sites and shed light on what is happening below ground.

GPR also has the potential to yield important information about soil types and their sub-surface layers. This information can be used to gain insight into the geological evolution of an area and even assess its structural stability for future bases and research stations.

This newly discovered complex, layered structure also suggests that smaller craters are more important and may contribute far more than those deposited by meteorites.

Perseverance And Tianwen-1 are currently active, and the first GPR images from Mars are expected to be published in 2022. But the first available on-site GPR data was from Chang’e -3, e4 And E-5 lunar mission, in which it was used to investigate surface layer structure The far side of the Moon and provide valuable information about the geological evolution of the region.

Despite the advantages of GPR, a major drawback is the inability to detect layers with smooth boundaries between them. This means that the gradual variation from one layer to another is not detected, leading to the misconception that the subsurface consists of a homogeneous block, when in fact it represents an entirely different geological history. may have a more complex structure.

our team developed a new method It is able to detect these layers using the radar signatures of hidden rocks and boulders. The newly developed tool has been used to process the GPR data captured by Chang’e-4‘s Yutu-2 rover joe landed in from the pit of karman, Part of aitken basin at the south pole of the Moon.

The Aitken Basin is the largest and oldest known crater, thought to have been created by a meteorite impact that penetrated the Moon’s crust and lifted material from the crust above it (the inner layer just below it). Our detection tool revealed a previously unseen crust structure in the first 10 meters of the lunar surface, which was understood to be a homogeneous block.

Using our method, we can more accurately estimate the depth of the upper surface of the lunar soil, which is an important way to determine the stability and strength of soil foundations for the development of lunar bases and research stations.

This newly discovered complex, layered structure also suggests that smaller craters are more important and may have contributed much more than material deposited by meteorite strikes and the overall evolution of lunar craters.

This means we will have a more consistent understanding of the complex geological history of our satellite and will enable us to more accurately estimate what lies beneath the surface of the Moon.
