Mars was habitable for life longer than previous predictions

Mars was probably habitable for longer

NASA’s Curiosity rover has been exploring Gale Crater from the day it landed on the surface of Mars in 2012. Gale Crater was a large lake of fresh blue water billions of year earlier but today it remains just as a big hole on this red planet. The material and chemical composition that are exist today in this dried lake gives an imprint that this lake might have been inhabited by some living organisms when Mars was warm enough to favor life.

The rover Curiosity is analyzing the material re-construction and happening after the red planet became inhospitable. A recent finding by the rover reveals that Mars’ chemical and physical components were enough to support life 3 to 3.8 billion years ago, but surprisingly it was the time when life started to evolve on the Earth.

Scientists said that initially Mars was cold, then became warm and then with the change in the atmosphere eventually lost all its water by transforming into vapor.
