The theory of current water existence on Mars rejected

According to RCO News AgencyThe set of lines observed on Mars, sometimes reaching thousands of meters in length, were at first glance in the form of water on the dry, endless surface of the planet. There were also darker lines in the background of uniform and low -dairy hills.

According to Fuchrism, over the years and more data collection, there were many questions about the nature of these lines. According to a new study, a team of scientists has concluded that these lines have nothing to do with current water.

Adomas Valantinas, an extraordinary researcher at Brown University and the author of this article, said: One of the main goals of Mars research, including the possibility of liquid water on its surface, is to understand the current surface processes of the planet. In this study, we examined these features, but we found no evidence of water. Our dominant hypothesis is based on drying processes.

For decades, these lines have fascinated scientists and have shaped theories of salt accumulation and possibly water flow to the dry and cold Mars surface that only reaches higher temperatures above the freezing point. Scientists in this theory believed that these lines could be a good place to find signs of Martian life.

Now the new findings have questioned the previous views. The precise and comprehensive map of Mars, which shows more than half a million features of the planet’s surface lines, has made it possible for scientists to examine the broader and more comprehensive image of the phenomenon.

“After preparing this global map, we were able to compare it with databases and lists of other factors such as temperature, wind speed, humidity rate, stone slip activity and other factors,” said Valentin Bickel, a researcher and author of this article. As a result, we were able to examine the relationships between these features in hundreds of thousands of things to better understand the conditions in which these lines are formed.

The results showed that these lines were not related to the factors associated with liquid water or ice -related in terms of slope, surface temperature, or humidity level.

Scientists believe that these lines are mostly due to severe winds and areas with high dust accumulation. Their hypothesis is that the thin layers of dust fall on the steep slopes and form these lines as a result of severe winds and clashes of meteors or Martian earthquakes.

In other words, these lines are not a good place to live, and the hope of discovering microbial life in these areas is very low.

At the same time, NASA is likely to be more practical for future studies with exploration spacecraft; Because the risk of contamination by alien creatures is very low.

This study is published in the journal Nature Communications.
