Water May Have Flowed Across Mars Shockingly Not That Long Ago
]]>Meteorite that smashed into Mars shook planet, NASA says

CommentsScientists who study Mars on Thursday revealed the remarkable Christmas gift they received from the planet last year.
So, we think that the rift valley has water, and apparently this finding is at low latitudes as well. I am not sure just how low, but it suggests, that much of the warmer parts of Mars may have what is needed.
Done.

The evidence of possible water turns out to have been a mirage ...

Despite the sad news, there is still a lot that we don’t understand about Mars. But, this also isn’t the only theory about the Martian south pole’s discovery, either.
According to SciTech Daily, a Mars geophysicist with York University named Isaac Smith has proposed another possibility. Smith believes that the bright radar signatures that we witnessed at the Martian south pole could be a type of clay that is made when water erodes rock. He believes we could use those signatures to learn more about Mars’ history with water.
Smith also said that Grima’s finding has some beauty to it. Ultimately, it could point us to other places where water may have been before. Even if the discovery of groundwater at the Martian south pole does prove to be a mirage, we can still hold onto hope. Of course, it’s impossible to know anything for sure. All we can do is theorize until we’ve been able to send explorers to Mars. Unfortunately, that’s still a long way from happening.

So liquid brine could exist very close to the surface of Mars, provided that a layer of icy regolith prevented evapouration. It is entirely possible for Martian regolith to be wet with cold salty water, with a thin crust of ice over the top. Photosynthetic algae might even live in such brine if only they could stand the salt and the extreme cold. There aren't many living things that can survive in brine at temperatures colder than -20C. But in principle, saturated brine could exist very near the surface of Mars as a liquid.
]]>Your mention of the Great Salt Lake caught my eye ... I had the opportunity to drive across a part of it some years ago, on a planned visit to Salt Lake City.
Your discussion of interaction of brine and water in the air inspires a question I am hoping you will find interesting.
Do you suppose it might be possible/practical to capture water in the moments after it is liberated from the liquid of the open ocean, and before it rises to make clouds?
In Nature, on Earth, water is liberated from the ocean (and other bodies of water) by Solar energy, whereupon it is whisked away for a long journey around the planet until it encounters conditions that cause it to form droplets, and then to fall to Earth.
What I'm speculating about (and inviting your consideration) is the possibility that humans might be able to "harvest" water vapor and deliver it to the places on Earth where it is needed.
Whatever technology might be developed for Earth could (presumably) be applied on Mars, where evaporation of any water brought to the surface would be much more swift.
Edit #1:
I asked Google for information about dehumidification. Dehumidification is the process Nature uses when it dumps water from the atmosphere onto the surface of the Earth below. While Nature's process is effective, it is not efficient. It persists in dumping water wherever it wants, instead of where humans need it (a) or (b) ** don't ** want it.

Featured snippet from the webWorking on the same principle as a refrigerator, moisture-filled air is drawn into the dehumidifier and passed over a cold, 'refrigerated' coil. The damp air condenses on the cold coil into water droplets which are collected in the water tank.

What is needed is a way to capture water molecules after they have been liberated from the ocean by sunlight, and before they escape to the upper atmosphere where they are whisked away by winds.
Whatever solution is found needs to use solar energy, because that is the mechanism used by Nature, and it delivers megatons of water over the surface of the Earth in a continuous delivery mode.

]]>Oh by the way, I must confess, that I think that it is possible that the solar wind can induce electric currents in objects that it passed by.
Done Dum.
The above may be proven wrong, BS.
However the main point is how would you recognize cryovolcanism on Mars when it might occur else than a polar ice cap. It would erode as exposed, and leave a dirt covered stump I think.
Mud volcano's would be an exception as they might just freeze up and/or dry out.
Dum Dum.
I seem to be still spewing. Well if somehow an aqufer of lesser dimensions were melted, and then froze, I suggest that if it froze from all sides, the only pressure relief might be downward into a lower aquifer, of if that were not possible upward to the surface to be an ice volcano.
Dum to the.......Not for sure.
No...."I don't know"

The article at the link above contains a healthy mix of scientific reporting in favor of the proposition (deep radar observations) and equally persuasive scientific argument against the proposition.
The radar data itself would appear to be accepted by all parties.
One detail I found intriguing was a guess that the interior of Mars may contain more heat than is generally thought to be present.
The lack of active volcanoes would seem (to me at least) to be a signal that the heat in the core (that had to have been present when the planet formed) is not being replenished by radioactivity as it is on Earth.
Still, one scientist interviewed for the article at the link above seems to think there might be enough residual heat flowing from the interior to keep water liquid at locations in the crust where it would otherwise be frozen.
It is that sort of healthy debate that ** should ** lead to future discoveries.
