Default Near surface liquid water on Mars.

The results from the MER rovers suggest there might be small amounts
of near surface liquid water in the form of brines to explain the
stickiness of the surface at the landing sites:

Into the Briny Deep - Perhaps.
http://www.astrobio.net/news/article842.html

It is also known that capillary action alone can significantly depress
the freezing point of water, perhaps down to -40 C:

Mars and Muddied Waters?
Low Freezing Point
Summary: Can Mars support liquid water? So fundamental a question was
hoped to be resolved with high-resolution orbital images, but the
debate on whether Mars was once wet and warm has a twist: liquid water
may be trapped in the porous soil, even well below its normal freezing
point.
http://www.astrobio.net/news/article652.html

Freezing-resistant liquid water in porous media, a possible mechanism
to account for the fluidized transport of sediments on Mars: an
example from East Gorgonum crater.

It is interesting then that some near equatorial sites such as Gusev
and Meridiani have mean annual surface temperatures at 234 K or -39 C.
See the linked image below.
Then the liquid water could persist at these sites year round.

It is a bunch of NASA bull**** for loud public consumption. Suppose
it were not pure bull****. A NASA geek takes some fine-grained
whatever, wets it with saturated brine, sticks it in the giant NASA
vacuum chamber with a volunteer in a space suit, and said brave
pioneer plays with the miracle stuff at 7-10 torr and -10 C. NASA
makes a movie and calls a press conference.

"Melting Point-Depressed Pore-Occluded Brine and Anomalous Martian
Regolith Physical Properties - We Must Send a Man to Mars Right Now."

If there were large concentrations of halide or water a few inches
deep, various spectroscopic satellites orbiting Mars would have
screaming motherboards and NASA would hold a press conference. If
Mars has been wet with brine these past 5 billion years, there would
be stuff growing in it - it would be a planetary ecosystem of immense
volume with only modestly adverse properties. Stuff in Antarctica
lives in worse.

NASA is screwing with your credulity.

NASA isn't smart enough to conspire. NASA professionally manages.
Case in point,

http://www.cnn.com/2004/TECH/space/0....ap/index.html

Either NASA has it or NASA don't got it. That isn't science, that is
Hollywood flack fluttering in a mighty wind. Did the insanely
expensive Robot Wars reject image a fossil? Or do we have presumptive
proof that maybe this could be an aqueous sedimentary deposit, except
for some conflicting data like maybe it is a aeolian deposit or merely
some random compacted crap?

**** or Shinola? Uncle Al, knowing some folks who work at JPL up the
road, predicts "ambiguous **** packed into a Shinola tin and tied with
a shiny loud ribbon."

I'd deeply enjoy a fossil. Sending two sad sack RC cars to Mars, $1
billion. Seeing the Vatican **** its silk panties jointly and
severally, priceless. "'One Creation' is only a metaphor. Earth is
the only planet with SALVATION!" Just you wait and see. Let the
Mormons chip in and send missionaries to Mars the way Russian Quakers
took up a collection and removed all the Doukhobors to the New World
in 1899. Even Quakers couldn't stand god-spewing Doukhobors, nor
could Canadians - and Canadians swallowed Quebecois with nary a burp.
Doukhobors were banished to the Canukistani Great Plains where the
resident pacifist Mennonites - also pariahs for having god jammed up
their asses - were motivated into killing rages. Talk about the power
of religion.

NASA doesn't conspire. NASA lies.

That was the plot in Starship Troopers,
except it was a different planet, but it *was* Mormons.
