How Much Water Does Mars Have?

I was searching for something else, but I came on a number to answer that in this link:
https://www.scientificamerican.com/arti … t-on-mars/
Quote:

Steve Clifford, an expert in Martian hydrology at the Planetary Science Institute in Arizona who was not part of the project, is not ready to count out the role of oceans in forming Mars’s brines. "You need the presence of water to have these brines," he says. Clifford points out that whatever water survives on Mars today—and researchers think there is enough to cover the entire surface with water at least half a kilometer if not a full kilometer deep—requires even more to have existed in earlier times, essentially assuring the Red Planet’s somewhat watery past.

So of course one of my pet projects is to use solar energy in a relatively primitive way to warm up water and inject it into an ice covered pool.  So it would seem that there is enough where you could fill massive basins with ice covered pools.  Likely dust storms would dump dust onto their surfaces and eventually protect them to some extent from evaporation.

I am going to try to be careful not to venture too far into terraforming Mars, and power production as the topic here is "Water on Mars".
However it is indeed a Terraforming and power production and storage technique.  The quantity of water mentions encourages me in every way.  I will go to the Terraforming section with this same material now, and perhaps elsewhere.

I like people who criticize angels dancing on a pinhead.  I also like it when angels dance on my pinhead.

The article indicates alternate methods for the Earth to have water, and that they speculate that the Earth has;
Quote:

Adding up the quantities cached in several places, Wu says, "Our planet hides the majority of its hydrogen inside, with roughly two global oceans' worth in the mantle, four to five in the core, and of course, one global ocean at the surface."

And then so I think that this might apply to Mars, and just maybe even the Moon, depending on how the Moon was formed.  Most theories of the Moons formation would say no, but we will need to have better ground truth from the Moon to know for sure.

If during the history of Mars Hydrogen tended to migrate from the lower regions, then it may be that all porosity of the regolith could be icy, except for the vacuum dried surface.

It actually makes sense that underground cryovolcanism would have occurred during and after the real volcanic eruptions became seldom or none.

Ship 500 gallons of water to mars and do salinity test for evaporation with each gallon testing for when it freezes when exposed to the mars atmosphere. Tag the water with a dry that can be traced from the orbiting satelites to watch where it goes. Repeat until you have liquid water that does not eveporate away.....

There's already much quantity of water on the surface derived from condensation and collected. Clue, look for the reflections in the pools?

Re: How Much Water Does Mars Have?

Nice examples of "Earth desert mirages"

No stranger to the western US deserts, I've clocked hundreds of miles, off road in the Mojave desert aboard my trustee two wheeled machines and have seen too many mirages to wave a stick at.

The difference is this. If you see a "inverted" reflection "in" the vision, it's more than likely water.

Still, a mirage requires less dense hot air at the surface both of which are supposedly not present on Mars. The possibility of "inferior" mirages I guess could occur but unlikely.

I have some 3D images showing vast water puddles from the Pathfinder lander but you will need anaglyph glasses. Do you have a pair?
