Title: Re: Standing Body of Water Left Its Mark in Mars Rocks
This is all very interesting, Gary, but please
note that I've never argued that the current evidence for water chemistry is
flawed. I have no trouble with the conclusions arrived at so far about
water chemistry. And it's good

Michael,
First, may I suggest a better question to bat about may be if there
is now mounting evidence for abundant liquid water once on Mars,
where did it go and why?. I appreciate your pursuit of a competing
hypothesis for liquid CO2, because I think in trying to suggest it,

As for where much of the trace surface water on Mars might have come from,

Michael,
OK, since you asked, sit down and I will give you a mini-lecture
on molecular chemistry. The evidence for water is the salts.
I have it from a particular Mars planetary scientist (pers. comm. on
Thursday) that the now-famous

I am curious as to whether all this hand waving about
CO2 flows may be more about exorcising the ghost of
Percival Lowell rather than describing what actually
is found on Mars.

So does this mean that Bush's Mars proposal is a faith-based initiative?

Fiscally, yes. If it gets us sustained teleoperated presence on the Moon,
though, it's okay.

Isn't "standing body of liquid" the safer hypothesis?
And what would that liquid be, if not water?
