Almost all the dust on Mars comes from one place



Mars is the fourth planet of our sun and is famous for its exquisite reddish appearance. The surface of Mars is very cold and dry and covered with iron oxide-rich dust, giving the planet its iconic red color.

Recently researchers have observed a new fascinating fact about the Martian surface and the dust on it. The dust, which is abundant on the Martian surface, mostly comes from a single source and the source is near the equator of the Red Planet. This thousand kilometer long geological formation is called Medusae Fossae Formation. The composition of this feature is similar to that of dust in the Martian atmosphere.

"Mars would not be nearly as dusty if there were not this huge deposit that gradually erodes over time and essentially pollutes the planet," said co-author Kevin Lewis of Johns Hopkins University.

As Neighboring Planets Earth and Mars have many things in common, both of which have a similar rocky composition and structure and both orbiting the Sun within their circumstellar habitable zone, and even Mars once had water on its surface that has probably contributed to the global dust reservoir on the planet. 1

Mars so much dust because none of these processes are active on Mars? "The lead author of the study, Lujendra Ojha, said:

To answer this question, the researchers investigated the chemical composition of mossy dust. Lander and Rover far apart on the planet showed that dust is enriched with sulfur and chlorine all over Mars. When the researchers examined the data collected by the spacecraft Mars Odyssey, they were also able to determine their source. They found that Medusae Fossae Formation on Mars has a wealth of sulfur and chlorine. Its ratio also coincides with the very different sulfur-to-chlorine ratio found in marshmallow.

Expert Kevin Lewis says. "It only potentially explains a great deal of how Mars has reached its current state."
