Mysterious dark stripes that flow MarsThe surface surface may not be the result of running water after all, it suggests a new artificial intelligence analysis (AI).
The stripes, observed for the first time that they ran along the cliffs of Mars and the Crater walls by NASA’s Viking mission in 1976, thought for a long time by the scientists who formed as a result of the ancient water flow through the surface of the planet now mostly dried.
But an algorithm of the trained in slope stripes has revealed a different origin for the stripes, probably formed by the wind and dust, not the water. The findings, published on May 19 in the magazine Nature communicationsIt could have important implications about where humans choose to explore Mars and the places where they seek evidence of a possible ancient life.
“That is the advantage of this Big Data approach”, co -author of the study Valantinas de Adomasa planetary scientist at Brown University, said in a statement. “It helps us rule out some orbit hypotheses before sending spacecraft to explore.”
Sinewy lines are darker than the surrounding Martian soil and extended for hundreds of meters downhill. The shortest life of these characteristics is called the recurring line of Slope (RSL), and arise regularly during the warmer spells of Mars.
This led some planetary scientists to suggest that seasonal temperature fluctuations could be causing frozen ice or aquifers to melt, or wet air to condense, sending salt water currents that extend through the planet’s craters. If this were true, I would make these regions of particular interest for the future missions of Mars.

To investigate this, the scientists behind the study trained an automatic learning algorithm in confirmed gusty sightings before making it scan through 86,000 satellite images to create a 500,000 gust characteristics map.
“Once we had this global map, we could compare it with databases and catalogs of other things such as temperature, wind speed, hydration, rock sliding activity and other factors.” Bickel said. “Then we could look for correlations in hundreds of thousands of cases to better understand the conditions under which these characteristics are formed.”
Using the map, the scientists found that the stripes were more likely to form in places where the wind speed and the deposition of dust was high, which suggests that they came from layers of fine dust that slid of the steep slopes.
Other studies have indicated tempting evidence of water And even life On Mars. If the study findings are maintained, they could serve as a guide to sifle among the potential clients of the red planet and their red herring.
