Liquid saltwater is likely present on Mars, new analysis shows
"A large amount of independent physical and thermodynamical evidence shows that saline water may actually be common on Mars," said Nilton Renno, a professor in the U-M Department of Atmospheric, Oceanic and Space Sciences and a co-investigator on the Phoenix mission.
"Our favored model at present for TSL formation is
that shallow brines mobilize thin flows"
