The distinctive red color of Mars comes from the metal Verihideret, which is only formed in the presence of cold water, which is a new study.
Ferrihydrite also is also at a temperature less than other minerals that make up the surface of the red planet called appropriately, such as hematite, which was previously considered the main cause of its degree.
“This indicates that Mars may have had an environment capable of maintaining liquid water before moving from a wet environment to a dry environment billions of years ago,” NASA said in a press statement this week.
NASA has partially funded the study.

The researchers in the study, published in Nature Communications this week, analyzed the data from several Mars missions, including many Mars Rover, and the results were compared to laboratory experiments. “The team tested how the light interacts with the particles of the Verhydrite and other minerals under the simulation conditions.”
“The main question about the reason that Mars is red is considered hundreds if not for thousands of years,” Adam Valletinas, the lead author of the study in a statement.
Valantinas is a post -PhD classmate at the University of Brown began studying as a doctorate. A student at Bern University in Switzerland.
“From our analysis, we believe that Ferrihydrite is everywhere in dust, and perhaps also in rock formations, too. We are not the first to consider Verheidrit a reason for the reason that Mars is red, but we can now test this using observation data and new laboratory methods mainly to make Mars dust in the laboratory.”

The senior study, Jack Al -Khulkal, described the study as the “opportunity to open the door.”
“It gives us a better opportunity to apply the principles of mineral formation and conditions to take advantage of time in time.” “What is more important, is the return of samples from Mars that is now collected by the perseverance Rover. When we repeat it, we can already check whether this is true.”
The research shows that Mars was probably a great but wet climate and may be in its old past.
NASA said the Mars atmosphere is very cold and then to support life now, but billions of years ago the planet had an abundance of water, and it was also proven in the fieridrich in its dust.

“These new results indicate a possibility that is likely to be valid for Mars and highlights the value of coordinated research between NASA and its international partners when exploring basic questions about our solar system and the future of space exploration,” Jeronimo Villanueva, co -director of the strategic sciences of the Solar System Exploration Department in NASA Gayear Airways in Maryland,

“The researchers want to understand is the ancient Mars climate, and chemical processes on Mars – not only old – but also exist,” said Valantinas.
He continued, “Then there is a questionable question: Was there a life ever? To understand that, you have to understand the circumstances that were present during the period of the formation of this mineral. What we know from this study is the points of evidence to Verheidrret to form it, and for the event, there must be an occurrence everywhere, as there is a plan for a mixture, as the extracts that give up on that. The iconic red appearance.”
