Traces of Water on the Surface of Mars Examined

At one time, buying land from Mars was a very popular investment tool. It is obvious that we humans will never leave the planet, which is still unknown whether there is life on it or not. Among other planets in the solar system planet most likely to have life Every day there is a new research on Mars.

Perhaps billions of years ago, on Mars, whose vital functions are explored, as well as its past. that there is water A lot of evidence has been uncovered, but still not enough to understand the full history of Mars. Scientists on Mars’ possible past their newest assumptions transferred.

They tracked the salt on Mars

Researchers are trying to understand the last time water flowed or stopped flowing on the surface of Mars and to reveal the past map of the planet more clearly. took advantage of the salt on its surface. on the surface of Mars many different salts detected but researchers Ellen Leask and Bethany Ehlmann Also known as table salt a compound of sodium chloride of chloride they followed. These are the salts that dissolve most easily in water, meaning that if there is water around, they will dissolve in chloride salts. For this reason, salt deposits on the surface of Mars, because the last water in that area has dried means there.

Salt deposits found higher than basins

map of salt deposits When they removed it, researchers gained a lot of information. If the waters on a planet are starting to dry up, you expect the remaining water to collect in basins. However, according to the map the researchers drew, most of the salt deposits higher than the basins and in tight spaces. This situation means that the water flows into the channels but before they reach the basin they fill. it’s dry showed.

More likely to have previous ice deposits on the Martian surface

Finally, researchers who want to look at the age of the salt deposits, due to the narrowness of the places where the deposits are located. Failed to perform crater count. Instead, they focused on the history of the rock beds beneath the deposits. in a region 3.3 billion year old rock located on and With an event that happened 2 billion years ago a changing salt bed found it. In another region 2.3 billion years A salt deposit located on the volcanic deposits was detected before. With this research; When did Mars get this cold? will not allow liquid These are the newest information we have learned about the atmosphere.

In line with these results, researchers show that Mars has been in the past. does not have a permanent presence of water instead of seasonally holding water and large puddles of ice thinks it might.
