There may be less liquid water on Mars than previously thought That is the reality of the situation. Image: Pixabay There is good evidence in the form of observable river deltas, and more recent measurements made on Mars’ surface suggests that liquid water did flow on Mars billions of years ago. Mars likely has less water in the form of brines- water-salt mixtures that are more resistant to boiling, freezing, and evaporation. Scientists from the Arkansas Center for Space and Planetary Sciences suggest that Mars has even less liquid water than previously thought. Scientists conclude by studying combined data on brine evaporation rates with a global weather circulation model of the planet. ....

In a new study published in the Planetary Science Journal, a team of U.S. scientists combined experimentally verified data on brine evaporation rates along with a global circulation model to develop a new extensive framework of brine stability on the surface and subsurface of Mars. They found that the equatorial regions of Mars typically have temperatures too high for stable brines, while high latitudes are susceptible to permanent freezing.

Brines are mixtures of water and salts that are more resistant to boiling, freezing and evaporation than pure water. ....
