They were looking for clays that would imply liquid water flows.
Perhaps they found some good, old fashioned clay in the frozen mud.
Clay also holds lots of water - that is quite significant to know and
evokes lots of Earth science. Maybe they are excited with the
resulting mud pies. Reminds me when my friend and I put all kinds of
things in her Kenner Easy Bake (light-bulb) oven, and they
sloooooooooooooooooooowly released their water until finally curdling.
I guess that would have been good resume material for the mission
chemistry projects...

Hi, All,

    The interesting part is not a potential discovery
of... something. These is the parts I find fascinating:

    Is the question what sort of "spin" should we put
on Martian permafrost? What are the political implications
of Martian soil? Should we hold up the announcement
until after the elections? What is the President's position
on "dirt," anyway?

    Well, Galileo had to run his findings by the Inquisition.
In the old Soviet Union, scientists had to have the approval
of branches of the Central Committee to publish or speak.
This is not like that, of course; this is completely different.

    It just looks exactly the same.

    Hmm, you don't want the news to be "benign,"
meaning "good, helpful"? Does this mean you'd prefer
the news be something its opposite, namely "malign"
(evil, harmful)? I'm trying to figure out what a "malign"
Martian soil component would be.

It's a fine guessing game. Here a description of the MECA
package and what it does and how it does it:
http://planetary.chem.tufts.edu/Phoenix/MECA.html
The Wet Chemistry Lab has "sensors... for the determination
of a wide variety of inorganic anions, cations, selected
heavy metals (via ASV), and electrochemical parameters."
There's a list of test targets in that URL. None of them
look that exciting to me, but chemistry always was my
worst subject.

Ideas?

... as in Alaska. Because, see, the Phoenix lander is at the cold polar
outskirts of Mars, and Nome is at the-- ah, forget it.

http://www.universetoday.com/2008/08/02/the-white-house-is-briefed-phoenix-about-to-announce-potential-for-life-on-mars/

It would appear that the US President has been briefed by Phoenix
scientists
about the discovery of something more "provocative" than the discovery
of
water
existing on the Martian surface. This news comes just as the Thermal
and
Evolved
Gas Analyzer (TEGA) confirmed experimental evidence for the existence
of
water
in the Mars regolith on Thursday. Whilst NASA scientists are not
claiming
that
life once existed on the Red Planet's surface, new data appears to
indicate
the
"potential for life" more conclusively than the TEGA water results.
Apparently
these new results are being kept under wraps until further, more
detailed
analysis can be carried out, but we are assured that this announcement
will
be
huge.

So why is there all this secrecy? According to scientists in
communication
with
Aviation Week & Space Technology, the next big discovery will need to
be
mulled
over for a while before it is announced to the world. In fact, the Jet
Propulsion Laboratory science team for the MECA wet-chemistry
instrument
that
made these undisclosed findings were kept out of the July 31st news
conference
(confirming water) so additional analysis could be carried out,
avoiding any
questions that may have revealed their preliminary results. They have
also
made
the decision to discuss the results with the Bush Administration's
Presidential
Science Advisor's office before a press conference between mid-August
and
early
September.

Although good news, Thursday's announcement of the discovery of water
on
Mars
comes as no surprise to mission scientists and some are amused by the
media's
reaction to the TEGA results. "They have discovered water on Mars for
the
third
or fourth time," one senior Mars scientist joked. These new MECA
results
are,
according to the Phoenix team, a little more complex than the water
"discovery."
Scientists are keen to point out however, that this secretive news will
in
no
way indicate the existence of life (past or present) on Mars; Phoenix
simply
is
not equipped make this discovery. What it can do is test the Mars soil
for
compounds suitable to support life. The MECA instrument does have
microscopes
capable of resolving bacterial-scale life forms however, but this is
not the
focus of the forthcoming announcement, sources say.

This new MECA discovery, combined with TEGA data will probably expose
something
more compelling, completing another piece of the puzzle in the search
for
the
correct conditions for life as we know it to survive on Mars. Critical
to
this
search is to understand how the recently confirmed water and Mars
regolith
behave together under the Phoenix lander in the cold Martian arctic.

The MECA instrument had already made the landmark discovery that Mars
"soil"
was
much like the soil more familiar on Earth. This finding prompted
scientists
to
indicate that the minerals and pH levels in the regolith could support
some
terrestrial plants, indicating this would be useful for future Mars
settlers.

What with the discovery of water, and the discovery that Mars soil is
very
much
like the stuff we find on Earth, it is hard to guess as to what the
MECA's
second soil test has discovered. What ever it is, it sounds pretty
significant,
especially as NASA and the University of Arizona are taking
extraordinary
steps
to avoid any more details being leaked to the outside world. I just
hope
were
not getting excited over something benign.
