NASA scientists discover evidence that water is flowing on Mars, the possibility of discovery of life forms increases

NASA is "An important scientific discovery about Mars"We announced the result of the Mars survey on NASA TV from 0:30 on September 29, 2015 in Japan time. Its content is that it discovered the most decisive trace so far that "water is flowing" on Mars, and the discovery of this time has made the possibility of existence of life forms near the crater wall of Mars dramatic It is increasing.

In the photographs of the valley and the crater part taken from the Mars orbit, there are things like marks made by the flow of water on the Earth's surface in the summer when the temperature of Mars rises, and this trace is seen in autumn and winter when the temperature drops I knew it was gone dry. However, it is unknown where the water thought to be flowing on the surface of Mars came from, and it is unknown why the surface of 0 degree or less is flowing in the liquid state, and the head of many scientists I was troubled.


Meanwhile, scientist Michael Mayer, who plays an important role in NASA's Mars research program, said, "Today, we found that there is liquid water on the surface of Mars, It is considered to be an environment where life can live, "he reveals that he found traces of water flowing on Mars.

The trace means that what was discovered as a result of investigating what type of chemical reaction is occurring on the "traces formed by the flow of water" using a spectrometer mounted on a satellite for Mars exploration is. Research was conducted by Mr. Lujendra Ojha of Georgia Institute of Technology and his research team. The research team used a spectrometer to investigate the reflection of infrared light and found a hydrate salt on the trace where this water flowed, which is the definitive proof that water exists on the surface of Mars I will.


According to the survey so far, it was known that "the trace formed by the flow of water" appeared on the surface of Mars when the surface temperature rose more than -23 degrees, but " Will it flow in liquid form? "Was unclear.

According to the contents announced on NASA TV, the melting point of pure water on the thin Mars of the atmosphere is 0 degrees same as the earth, but the boiling point is greatly different from 10 degrees. However, a hydrated salt was found in "a trace formed by water flowing" discovered on Mars, and if the perchlorate contained in it is dissolved in water, the aqueous solution will be on the Mars from -70 degrees to 24 degrees It will be able to exist as liquid in the range. From this, it was resolved that "Why is water flowing in liquid state even if it is 0 degree or less" that was a longstanding mystery?


The hydrated salt was discovered on the crater such as Mars Hale, Parikiel Horowitz and Alfred Mcuen, a geologist at the University of Arizona, on a huge valley called Coprates Chasma "remained on the surface of Mars We should investigate these places when searching for living organisms to do. "

At the moment, scientists are intensely investigating about where water is coming out. "Because there are many porous rocks on the surface of Mars, underground ice beneath it melts out in the summer and flows on the surface of Mars" or "Aquifers including salt exist below the surface of the earth There are multiple thoughts such as "There is," but with these ideas can not explain the existence of water flowing out from the top of the crater wall. According to McCuen that it is more credible than these ideas, the idea that salt on the surface of Mars absorbs moisture from the atmosphere and flows through the earth's surface. this is"DeliquescenceIt is a phenomenon called "phenomenon seen in the Earth Atacama Desert."

With this discovery, the possibility of space exploration institutions including NASA to discover living matter on Mars will dramatically increase, and in the future humanity should procure water on Mars in the event of terafalling to Mars It also means that the point turned out.
