How Mars Turned Red: Surprising New Theory

Do you think that the colour of Mars is always red? In fact, maybe your answer is wrong!
Mars was not always red, according to a new theory for how the planet took on its characteristic ruddy hue.Until recently, Mars' color was thought to be a product of liquid water, which scientists think flowed over the planet's surface billions of years ago, rusting rocks. But after the Mars Exploration Rovers Spirit and Opportunity landed on the planet in 2004, they found evidence of certain minerals that would have been destroyed by water, suggesting that the red dust on Mars never came into contact with flowing water.
"That was a surprise to everybody," said Jonathan Merrison of the Aarhus Mars Simulation Laboratory in Denmark
I am always curious about the planets in space. And I have a habbit that I will collect many beautiful lanyards with images of different kinds of planets on each of them. Eveyrtime I show my collections to my friends , I feel so proud that I am better known in space then anyone else around me. This is my special habbit. Do you like searching for the mistery of the space?
Now new research has found a possible mechanism to explain Mars' rusty color without liquid water. In fact, the study implies that the red tones on the planet are a relatively recent development. A simple grinding down of rocks from erosion could produce a red mineral that stains the dust on Mars, the new thinking goes.
To test the idea, Merrison and colleagues sealed samples of quartz sand in glass flasks and used a machine to tumble them over and over. They found that the gentle process, which approximates the mild wind flowing over the Martian surface, is enough to cause erosion, reducing about 10 percent of the sand grains to fine dust particles over seven months.
In fact, since the process can occur relatively quickly, it could be that the thin red layer of dust on Mars is somewhat new. But I think the potential of humans are very powerful and we can learn more and more about space in the future.

Mars saw Mars of Destruction and cried blood.

It's all dried blood, that's why Mars is red.
