According to a study published in the journal Nature, Chinese rover Zhurong Mars collected data from sand dunes on the Martian surface and found that: The Martian ice age came to an extreme end about 400,000 years ago.. The research was conducted in a 3,300 km diameter region known as Utopia Planitia, which is considered the largest impact basin in the Solar System.

In addition to rover data from the China National Space Administration (CNSA), high-resolution observations from the China Tianwen-1 Mars orbiter were used in the study. Research shows that dunes have eroded over thousands of years, forming materials called transverse wind ridges (TARs).

Until then, researchers did not understand how these ridges, which are observed in the lowest mid-latitudes on the planet, form. Fortunately, the new study clarifies this question a bit more: TARs began forming between 2.1 million and 400,000 years ago. After this period, dark ridges began to form.

The research was carried out in international collaboration by teams from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), the Institute of Geology and Geophysics, and the Tibetan Plateau Research Institute of the Chinese Academy of Sciences (CAS); In collaboration with researchers from Brown University in the United States.

Ice Age on Mars

Estimation of the formation date of TARs was based on the number of craters at the top of the dunes. However, the most impressive thing, according to scientists, The dates coincide with records of the beginning and end of the last ice age on Mars.

Research recommendations The end of the ice age after the extreme change in Mars’ rotation angle, causing dark ridges to form after changes in wind direction at lower mid-latitudes. Currently, the planet is going through a geological epoch known as the ‘Amazonian climate’.

“Understanding the Amazon climate is crucial to explaining the current landscape, volatile matter reservoirs, and atmospheric condition of Mars, and to relate these current observations and active processes to ancient climate models on Mars. Observations of the current climate on Mars can help improve physical models. NAOC “Martian climate and landscape evolution and even creating new paradigms,” said Li Chunlai, her partner and Study Principal Investigator.
