Did warm water once flow on Mars ?

Meteor impacts may have once heated up the water on Mars sufficiently for life to have developed.

The hunt for water on Mars has always been considered to be the key to finding life. We know that Mars was once rich in rivers and bodies of liquid water but was that enough for life to have developed ? In a new paper, John Bridges has claimed that impacts on the Martian surface may have heated up the water enough for this to happen. The analysis of certain meteorites believed to have come from Mars has revealed minerals that form due to the action of water near the surface including iron carbonate which only forms at higher temperatures.

"Our results show that environments associated with this type of fluid were habitable," wrote Bridges and physical science research associate Susanne Schwenzer. "The Martian subsurface fluid forming phyllosilicates provided habitable temperatures and many of the nutrients required for life."

"Water warm enough to support life once flowed on Mars, according to a paper published by a team of planetary scientists who probed Martian meteorites to make the discovery."

How long was the water warm for? If life was a freak event on earth, it probably happened after thousands if not millions of years of water being at the right temperature.

Yeah, I somewhat doubt that an extraterrestrial collision(or 2 or 17) could have "warmed" Mars enough to have warm water for any sustainable time to promote the growth of life.
