Previous discoveries have only been around temporary trickles of water and so to have found a massive reservoir of liquid hidden underground has been hailed a stunningly amazing result. The researchers say the lake was likely able to stay liquid because of salts from Martian rocks dissolving into the water, coupled with the incredible pressure of the ice above. 11 1 Link to comment Share on other sites More sharing options...

Seti42 Posted July 26, 2018 #4 Share Posted July 26, 2018 Aren't the Mars polar caps frozen carbon dioxide (AKA dry ice)? I don't see how liquid water could exist under that without being geothermally heated...Regardless of salt content. Maybe I'm missing something; I am not a chemist, lol.

High salt content and pressure from above. Water expands as it freezes, if it can't expand it'll stay liquid. More or less. There's videos of this online. 1 1 Link to comment Share on other sites More sharing options...
Ozfactor Posted July 27, 2018 Author #6 Share Posted July 27, 2018 This is an interesting read if you have the time, and the hypothesis of Mars being covered in oceans might be proven true https://en.wikipedia.org/wiki/Mars_ocean_hypothesis An artist's impression of ancient Mars and its oceans based on geological data The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water.[1] The Mars ocean hypothesis states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the planet’s geologic history.[2][3][4] This primordial ocean, dubbed Paleo-Ocean[1] and Oceanus Borealis,[5] would have filled the basin Vastitas Borealis in the northern hemisphere, a region which lies 4–5 km (2.5–3 miles) below the mean planetary elevation, at a time period of approximately 4.1–3.8 billion years ago. Evidence for this ocean includes geographic features resembling ancient shorelines, and the chemical properties of the Martian soil and atmosphere.[6][7][8] Early Mars would have required a denser atmosphere and warmer climate to allow liquid water to remain at the surface.[9] Link to comment Share on other sites More sharing options...

Apparently Mars soil still has a certain quantity of water . It is believed that most of the water on Mars didn't disappear with its atmosphere but was soaked underground.
