3 to 4 billion years ago, it was warm enough on Mars to spark major rainstorms and flowing water, which would have frozen shortly after, a new study has found. This could serve as evidence that simple life may have developed on Mars at a similar time that it developed on Earth.
It is not new information that Mars was once home to an abundance of water. But it has remained somewhat of a mystery whether the water on Mars was mostly liquid or frozen as ice, and how this may have changed over time. Warmer temperatures on Mars would not only signify the presence of liquid water, warmer conditions also make it more likely that life could have formed independently on the planet.
Study - Patterns - Surface - Mars - Deposits
One new study compares patterns on the surface of Mars made by mineral deposits with similar patterns on Earth in a wide variety of environments in locations including the Oregon Cascades, Hawaii and Iceland. The Earth data was compared to Martian mineral data collected by the Curiosity rover and the NASA CRISM spectrometer, which is currently aboard the Mars Reconnaissance Orbiter circling the planet.

Patterns - Scientists - Evidence - Mars - Period
By analyzing these patterns, scientists found evidence that Mars had at least one long period of severe rainstorms and flowing surface water which was followed by temperatures that froze this water.
"If this is so, it is important in the search for possible...
