Launched in 2020, the six-wheeled Zhurong - named after a fire god in Chinese mythology - arrived at Mars in 2021 and spent a year roaming around before going into hibernation last May. However small this watery niche, it could be important for identifying habitable environments, she added. The rover has now provided “evidence that there may be a wider distribution of this process on Mars than previously identified,” said Trinity College Dublin’s Mary Bourke, an expert in Mars geology. Martian frost has been observed since NASA’s 1970s Viking missions, but these light dustings of morning frost were thought to occur in certain locations under specific conditions. They ruled out wind as a cause, as well as frost made of carbon dioxide, which makes up the bulk of Mars’ atmosphere. Small pockets of water from thawing frost or snow, mixed with salt, likely resulted in the small cracks, hard crusty surfaces, loose particles and other dune features like depressions and ridges, the Chinese scientists said. “This is clearly a new piece of science for this region,” he said in an email. What’s notable about the study is how young the dunes are, said planetary scientist Frederic Schmidt at the University of Paris-Saclay, who was not part of the study.

But Qin said computer simulations and observations by other spacecraft at Mars indicate that even nowadays at certain times of year, conditions could be suitable for water to appear. The rover did not directly detect any water in the form of frost or ice. no more than a film of water on the surface,” co-author Xiaoguang Qin of the Institute of Geology and Geophysics said in an email. Studying the structure and chemical makeup of these dunes can provide insights into “the possibility of water activity” during this period, the Beijing-based team wrote in a study published in Science Advances.
