Study Reveals Young Mars Was A Wet World

The most comprehensive study ever conducted of minerals on Mars' surface reveals the planet has undergone three distinct geological eras throughout its history, with water playing a progressively lesser role in each.

If life as we know it here on Earth ever existed on the red planet, it could only have survived in the planet's infancy, during the earliest era, the study concludes.

"Starting about 3.5 billion years ago, conditions on Mars became increasingly dry and acidicâ€”not a pleasant place for any form of life, even a microbe," said study team member John Mustard, a geologist from Brown University.
