Mars has long been a fascinating area of exploration for humanity. Recent discoveries have begun to unearth the secrets hidden beneath the surface of the red planet. Interesting, polygonal structures have been detected deep within Mars, offering experts new perspectives on the planet’s structure. This new finding is among the discoveries of the Chinese rover Zhurong, the first Chinese mission to land on the red planet Mars. These structures on the surface of Mars are an exciting step towards unraveling the mysteries of the planet.
16 Buried Polygonal Structures Beneath the Surface
Zhurong, one of Mars’ major impact basins Utopia Planitia is doing research on it. Thanks to new technology that goes beyond the findings discovered by Viking 2 in 1976, it brings new information from this region to Earth.
China’s spacecraft is buried beneath the surface, which experts believe is formed by a freeze-thaw cycle. He identified 16 embedded polygonal structures. In a study published in the journal Nature Astronomy, Zhurong’s radar discovered these structures 35 meters below ground, marking the first time these structures have been mapped horizontally across 1.9 kilometers.
Early Atmospheric Changes of Mars
Previous evidence had shown that floods occurred in the basin about 3 billion years ago and that the structures were formed by sediment deposition and other thermal processes. There was no evidence that these structures were formed from lava, like some polygonal structures seen on Earth, such as the Giant’s Causeway.
But the study confirms that Mars’ early atmosphere was variable. It affects the formation of freezing and thawing processes he stated. This finding provides new understanding of the planet’s past climate conditions and geological processes.
Significant Climatic Transformation in Mars’ Past
Experts consider the possibility that Mars may have had a higher tilt in the past than it does today, and thus its seasons were extremely different. The authors of the study expressed their thoughts on this new finding as follows:
“Polygonal terrain occurring at low latitudes (~25° N) and most likely explained by thermal contraction cracking makes a compelling case for the high tilt of early Mars. “The structures covered by buried paleo-polygonal terrain, together with the examination of subsurface structures, indicate that Mars experienced a significant paleoclimatic transformation in its past.”
What Do These Findings Mean?
The 16 polygonal structures discovered under the surface of Mars by the Zhurong rover provide important clues about the planet’s past. These structures were found approximately 35 meters deep in Utopia Planitia, the vast plain of Mars. Researchers believe these polygonal structures were probably formed between 2,000 and 3,000 million years ago. During the Hesperian and early Amazonian periods They believe that it occurs. This finding indicates the existence of a humid environment on Mars in the past and shows that the planet was buried over time by geological processes.
The formation of the structures may be due to freeze-thaw cycles in cold climates observed on Earth. This process causes the soil to shrink and crack due to temperature drops. Over time, these cracks can widen and fill with ice, sand, or both, forming wedge-shaped structures that prevent the cracks from healing. This situation, Mars’ equatorial regions were once much colder and wetter, similar to Earth’s polar regions indicates that it may be possible.
These polygonal and wedge-shaped structures discovered on Mars are quite large. At approximately 70 meters wide and tens of meters deep, these structures are significantly larger than typical polygonal structures on Earth. This shows that the formation process on Mars is different from the ice wedge polygons on Earth.
The discovery of these structures supports an idea that Mars’ axial tilt has changed significantly in the past and how this change affected climate and potential habitability. This provides critical information for future Mars missions that will specifically focus on finding water and exploring the possibilities of ancient life on Mars.
In summary, these polygonal structures found by the Zhurong rover under the surface of Mars provide important clues about the ancient Martian climate and geological processes and provide important information about the dynamic history of the planet.
