Is Mars Dead?

Rate this resource

A Catalyst article explaining how new data suggests that it is very unlikely that life ever existed on Mars. When the presence of water was confirmed a few years ago, there was a lot of speculation that at least simple life forms had once lived there as water is essential for every known living organism. The latest data gathered by Rover vehicles on the planet’s surface suggests that the water was far too salty to support any life and that life on Mars would have been very challenging for even the toughest organisms at any time during the past 4 billion years.
