of China’s Chang-i-For Mission Moon car has helped scientists see ‘hidden’ structures beneath the surface on the side of the Moon not visible from Earth. This is a development that reveals billions of years of moon history.
The lunar rover Uto-to helped make the discovery with its Lunar Penetrating Radar (LPR), which uses sound echoes bounced back by collisions with unseen structures beneath the moon’s surface. Imagery deep below the surface.
The same lunar vehicle and mission lander made history in 2019 as the first man-made object to land on the far side of the Moon.
Scientists have previously used the lunar rover’s ground-penetrating radar (GPR), but those previous efforts helped map only the top 40 meters, or about 130 feet, of the moon’s surface. could meet In this new discovery, the ‘hidden’ structure was found at a depth of about three hundred meters (984 feet).
The new data shows that the first 130 feet below the moon’s surface are made up of layers of dust, soil and rocks.

Radar analysis also revealed the presence of a buried crater that was created when a large object hit the lunar surface. The analysis also helped map ancient lava flows beneath the moon.
The researchers explained in their research that ‘GPR sends electromagnetic waves into the interior of the Moon and listens for echoes from the lower layers. We use high-frequency channel data to detect the structure of the upper 40 m in the path of the lunar rover. The structure consists mainly of rock debris and clay.’
Scientists speculate that the broken rocks around the structure were likely debris from the collision.
He wrote that ‘Through this research we have discovered several layers of the upper layer of three hundred meters which possibly indicate a series of basalt uplifts billions of years ago.’
A new study recently published in the journal ‘Journal of Geophysical Research: Planets’ reveals that Chan
D’s lava was likely flowing into this part of the Moon billions of years ago.
The researchers discovered that the layers of volcanic rocks are thinner the closer they are to the Moon’s surface.
“The change in thickness of this lava flow shows a decrease in lava flow over time,” he said.
Based on this evidence, scientists said that since the moon’s formation four and a half billion years ago, volcanic activity on the moon gradually cooled when an object the size of Mars collided with Earth, resulting in one of its craters. The part broke off and eventually became the moon.
The scientists concluded that ‘thickness of the layers decreases with decreasing depth, leading to a gradual decrease in lava flow over time.’

**Interview with Dr. Li Wei, Lunar Geologist and Principal Investigator on the Chang’E-4 Mission**
**Editor:** Thank you for joining us today, Dr. Wei. The Chang’E-4 mission has made remarkable strides in lunar exploration, particularly with the recent findings from the Lunar Penetrating Radar (LPR). Can you elaborate on the significance of these discoveries?
**Dr. Wei:** Absolutely, and thank you for having me! The Chang’E-4 mission is groundbreaking as it explores the far side of the Moon, which has been largely unexplored. With the data collected from the Lunar Penetrating Radar, we can now visualize hidden structures beneath the surface, providing insights into billions of years of lunar history. This is crucial for understanding not only the Moon’s geological past but also the processes that have shaped its evolution.
**Editor:** You mentioned the LPR. How does it work, and what kind of structures has it revealed?
**Dr. Wei:** The LPR operates by sending sound waves into the lunar surface and recording the echoes that bounce back from various layers. This technique has allowed us to look deeper than previous ground-penetrating radar efforts, which only mapped the top 40 meters. We have now detected structures at depths of around 300 meters, including layers of dust, soil, and rocks, as well as a buried crater. This crater highlights significant impacts on the Moon’s surface over the ages.
**Editor:** That’s fascinating! Can you tell us more about the implications of discovering ancient lava flows beneath the surface?
**Dr. Wei:** Certainly! The detection of ancient lava flows suggests that volcanic activity occurred on the Moon more recently than previously thought. These findings challenge our understanding of lunar volcanic activity and provide clues about the Moon’s thermal history. Studying these flows can help us learn more about the Moon’s geological processes and how it compares to Earth.
**Editor:** It sounds like the potential for new discoveries is vast. What are the next steps for the research team now that this data is available?
**Dr. Wei:** Moving forward, we plan to conduct further analyses of the radar data to refine our understanding of the lunar subsurface structures. We will also compare our findings to samples from lunar missions and continue collaborating with international teams. The ultimate goal is to piece together the Moon’s history and how it fits into the broader context of our solar system.
**Editor:** Thank you, Dr. Wei, for sharing your insights. It’s exciting to see how the Chang’E-4 mission is contributing to our understanding of the Moon.
**Dr. Wei:** Thank you for the opportunity! We’re excited about the future of lunar exploration and the stories hidden beneath the Moon’s surface.
