BEIJING, July 10 (Xinhua) — The latest findings of China’s Mars Exploration Rover “Zhu Rong” on the dunes of Mars shed light on the geological and climatic changes the planet went through about 400,000 years ago, providing new insights for the study of climate evolution on Mars. Mars, according to a study published last Thursday in the journal “Nature”, one of the best scientific journals in the world. Mars is the planet most similar to Earth in the solar system, and it is believed that studying its evolution can provide a reference for the future of Earth. The sediment activities caused by winds are formed The most important geological process on Mars since the late Amazonian era, as it records the characteristics of the climatic environment and the process of climate change on modern Mars. The United States, they used a high-resolution orbital camera on the Chinese Mars probe “Tianwen-1”, the terrain cameras and multispectral cameras of the “Zhu Rong” rover, multispectral cameras, surface composition analyzers and meteorological instruments to obtain data from the surface of the Earth. Mars. The researchers analyzed wind directions and absolute model ages of Martian dunes in the southern part of the Utopia Planitia plain near the “Zhu Rong” landing site by studying its surface structure and the impact of the crater size-frequency distribution. In this context; Li Chunlai, a researcher at the China National Astronomical Observatory who led the study, said the researchers’ findings indicate that the region may have experienced a climate change characterized by a change in wind direction nearly 400,000 years ago, coinciding with the end of Mars’ ice age. The direction of the winds in the region shifted by about 70 degrees from northeast to northwest, which led to the erosion of bright sand dunes into dark longitudinal sand dunes. The study estimated that climate change resulted from a change in the deviation of Mars’ rotation. The study helps improve our understanding of the evolution of Mars. Mars climate, and can provide a reference for predictions of future climate change on Earth.
