The team concluded that these features were formed from small pockets of water from thawing frost or snow mixed with mineral salts. Once the water sublimated in Mars’ atmosphere, patches of hard crust and loose material were left behind, along with depressions and ridges. Like other features that formed in the presence of water, these were then preserved by Mars’ extremely cold and dry atmosphere.
“Instead, involvement of saline water from thawed frost/snow is the most likely cause. This discovery sheds light on more humid conditions of the modern Martian climate and provides critical clues to future exploration missions searching for signs of extant life, particularly at low latitudes with comparatively warmer, more amenable surface temperatures.”
