Mars suitable for Life?

Mars, the lovely red planet close to our earth, has shown some presence of the water and a research was conducted to see if life existed on mars.What is less known is how much water occupied the red planet and what happened to it during its geological march to the present. Mostly, evidence has pointed to a period when clay-rich minerals were formed by water, followed by a drier time, when salt-rich, acidic water affected much of the planet. Assuming that happened, the thinking goes, it would have been difficult for life, if it did exist, to have survived and for scientists to find traces of it.

Now a research team has provided a evidence for the presence of carbonates on Mars that shows that Mars could have been the home for watery environments in the past. The red planet close to the earth is neither too hot nor too cold. At the same time it is not too acidic. So it’s just the right place.

Finding carbonates indicates that Mars had neutral to alkaline waters when the minerals formed in the mid-latitude region more than 3.6 billion years ago. Carbonates dissolve quickly in acid, therefore their survival challenges suggest that an exclusively acidic environment later cloaked the planet.This could open up a range of environment on Mars.So the researchers say that the presence of carbonate mineral bolsters chances of environment on Mars.
