Mud cracks on Earth are often linked to cycles of wet and dry environments, which facilitate the development of complex processes for microbial life. The robotic spacecraft Mars Curiosity (Mars Curiosity) of the United States of America has sent information back from Mars that has discovered mud cracks on our neighboring planet That is believed to provide better information on geological and chemical processes and provide insights into how life on the Red Planet could have formed in the past billions of years ago.
Recently, an international team of researchers led by scientists from the French National Center for Scientific Research (CNRS) has revealed images of mud cracks on Mars obtained by a robotic rover passing through the Gale Crater. Gale Crater) on June 20-22, 2021, while passing through a rock fracture called Pontours, in the picture revealing a clear “T” and hexagonal cracks on the surface. Indicates the cycle of wet and dry conditions. which once occurred in this region “This is the first tangible evidence we see that Mars’ ancient climate had a consistent cycle of wet and dry like Earth’s,” he said. And such cycles are useful for molecular evolution that could lead to the emergence of life.
The study also revealed that the cracks in these muds indicate mineralization. Smectite clays, in particular, to sulphate-containing layers. This may indicate that Mars encountered an Earth-like environment during the Noakian-Hesperian transition. (Noachian-Hesperian) when 3,800-3,600 million years ago.
