Deep beneath the northern hemisphere of Mars lies a fascinating discovery made by the Chinese Mars rover Zhurong. Radar data has revealed the presence of 16 irregular polygons buried beneath the vast plain of Utopia Planitia. These polygonal formations, ranging in diameter from centimeters to tens of meters, offer valuable insights into the geological history of Mars.

Scientists from the Institute of Geology and Geophysics of the Chinese Academy of Sciences have meticulously analyzed the radar data collected along the rover's path, approximately 1.2 kilometers long and at a depth of 35 meters. The distribution of these polygons suggests that they are a common feature beneath Utopia Planitia, the largest basin on Mars.

But how were these polygonal polygons formed? One proposed mechanism is the cycle of freezing and thawing, resulting in the contraction and expansion of the Martian surface. This process could have created muddy cracks from dried wet sediments, columnar joints from cold lava, fractures from rock joining systems, and thermal contraction cracks.

Implications for Martian Climate Change

Explore the significance of the polygonal polygons in understanding climate change on ancient Mars.

The presence of these polygonal polygons also provides valuable insights into the climate conditions on ancient Mars. The stark contrast observed above and below a depth of approximately 35 meters indicates a significant transformation in water activity or thermal conditions. This suggests that climate change occurred at low to mid-latitudes during ancient Martian times.

Researchers believe that the drastic climate changes were likely influenced by the large tilt of ancient Mars. The planet's axial tilt, similar to Earth's seasons, could have resulted in extreme variations in temperature and weather patterns. By studying these polygonal formations, scientists hope to unravel the mysteries of Martian climate change and its implications for the potential habitability of the Red Planet.

The Tianwen-1 Mission: Unveiling Martian Secrets

Learn about the Chinese Tianwen-1 mission and its groundbreaking discoveries on Mars.

The remarkable findings of the polygonal polygons are a result of the Chinese Tianwen-1 mission, a groundbreaking endeavor to explore the mysteries of Mars. Launched on July 23, 2020, this mission consisted of an orbiter, lander, and rover.

The lander, carrying the Zhurong rover, successfully touched down in the southern part of Utopia Planitia on May 15, 2021. With an expected lifespan of at least 90 Martian days, or approximately three months on Earth, the rover has already provided invaluable data and images, shedding light on the geological features and potential signs of past water activity on Mars.

As the Tianwen-1 mission continues its exploration, scientists eagerly await further discoveries that will deepen our understanding of the Red Planet and its intriguing history.
