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.

A large number of the valley networks scarring Mars’s surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience.

A new scenario seeking to explain how Mars’ putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million years earlier and were not as deep as once thought.
