The collapse of Mars could help explain mysterious lines seen on the red planet's surface, a new study finds.Over the years, scientists analyzing the Martian surface have detected a cluster of dark, narrow, seasonal lines on the steep slopes facing the Sun in warmer regions. Previous research has suggested that these knockout black lines, known as recurring slope lines (RSL), signal that saltwater regularly flows on the Red Planet during the warmest seasons.

The latest mission to เกมสล็อตฟรี Mars has revealed that the planet has large amounts of ice underground. Previous work suggested that Mars' warmer spring and summer temperatures could help create at least a moment's salty brine to keep the liquid in cool weather. And sparse of the Red Planet Related: Finding Mars Water in Pictures However, geologists have uncovered problems with the salt water concept plaguing RSL, lead author Janice Bishop, a planetary scientist at the SETI Institute (Search for Extraterrestrial Intelligence) and NASA Ames Research Center, both of which are in Silicon Valley.

California For example, the slope angle that RSL occurs and the features around the entry point "are largely inconsistent with the fluid flow process," she told Space.com.Bishop and her colleagues now suggest that chemical reactions could make the Martian surface vulnerable to collapse, potentially explaining RSL.Although the surface of Mars today is dry and harsh and cold and dominated by wind and friction. But beneath the surface, interactions of microscopic salts with small ice and liquid water particles can still occur today.

Scientists focus on the chemical reactions between sulfate minerals such as gypsum and chloride salts, where table salt is a wide variety. "On Earth, the reaction between gypsum salts and chlorides causes parts of the cave to collapse into holes in soft sediment near lakes and salty ponds and to elevate roads," said Bishop.Researchers speculate that similar reactions could occur on Mars, although the cold and drought conditions slow these reactions,

I am very excited by the prospect of the chemicals acting beneath the surface of the planet. Tuesday despite the slow rate, ”said the bishop.In the new study, scientists have been conducting laboratory experiments on a mixture of sulfates, chloride salts, microscopic ice particles, and volcanic ash that resemble Martian soil. They freeze and dissolve the mixture at low temperatures, a type found on the Red Planet.

The researchers found a thin film of slushy water formed on the surface of the mineral grains. They suggest that these films can expand and contract over time, leading to changes and contractions under the Martian surface. Wind and dust on these unstable surfaces can cause landslides, causing lines seen on the red planet, Bishop explains.The scientists noted that in the future, the latest Mars surface mission to the RSL site could help test their models. They detail the findings online today (Feb. 3) in the journal Science Advances.
