Scientists believe that the red color of Mars grew up in a previous period in the planet’s past when liquid water was widespread on the surface.
The research, published in Nature Communications, indicates that the color of the red planet is better corresponding to the water -containing iron oxides, known as Ferrihydrite. The previous leading theory was that iron oxide was the hematite formed under the conditions of the dry surface. Verheidrit, on the other hand, is usually formed quickly in the presence of water.
The implicit meaning is that Mars should be “rust” early than previously thought.
The Verhydrite theory was proposed in others studies [PDF]. However, the latest research depends on notes from a variety of spacecraft, including the Mars vehicle (ESA) at the European Space Agency (TGO).
Data from Mars or Mars also used in NASA and ground measurements from the curiosity of Mars Rovers, Pathfinder, and the opportunity.
Scientists were based on this information in laboratory experiments, grinding and mixing samples before analyzing the results with the same techniques that the alain explorers use. They concluded that Ferrihydrite was the best match.
“We were trying to create the same dust of Mars in the laboratory using different types of iron oxide. Volcanic rocks, the best suitable for the minerals that the spacecraft in Mars sees,” said Adomas Valantinas, after a doctorate at Brown University in the United States.
“This study is the result of complementary data groups from the fleet of international missions that explore Mars from orbit and Earth level,” said Colin Wilson, the world of the TGO project and the ESA project from ESA.
“We are eagerly awaiting the results of the upcoming tasks such as Rosalind Franklin Rover from ESA and Nasa-Aisa Mars Odeh, which will allow us to investigate what makes Mars.”
Some samples collected by Rover persistent in NASA include dust, which can be analyzed on the ground to determine the content of the virhydride, assess the effects of the history of Mars water, and evaluate the possibility of life.
“Mars is still the red planet. It is just our understanding of the reason that the red Mars has turned. The main implicit meaning is that since Ferrihydrite could only be formed when the water is still on the surface, Mars is rust early Who we thought previously. “
Esa Stuck“The extensive chemistry of Mars’s stainless chemistry has been discussed because how to form it is a window in the environmental conditions of the planet at the time.
“It is closely related to this is the issue of whether Mars is valid for housing.” ®
