Martian soil&nbsp;is everywhere salty, like a salt pan(or worse).&nbsp; This started with Viking and was supported with the other missions which reported high levels of sulphates, chlorides, etc. in the soil.&nbsp; The same was true in the past. There was a paper recenly in Science&nbsp;that said that the Meridiani sediments were deposited under conditions far saltier than we have observed on on Earth, and grew global implications from this. &nbsp;We now have measurements&nbsp;that show that at at least one place, it was not paarticulaarly salt, 100s to 1000s of ppm.</p><p>2. Martian soil is everywhere strongly oxidising, like bleach.&nbsp; This was based on the Viking results which showed destruction of organic nutrients and absence of organics in the soil.&nbsp; Because the two Viking sites shown similar results this was extrapolated to the whole planet.&nbsp; we now know of at least one site where this is not the case.&nbsp; Oxidation potential was modest (it would be nice to see the numbers).&nbsp; Now, whether the Viking sites were really more oxidsing, or whether its oxidation potential has been exaggerated over time, I am not sure.&nbsp; I suspect the later is at last partly true.</p><p>3. Martian soil is everywhere acid, like a dried out car battery.&nbsp; Certian models indiated that Mars may have undergone acid vog weathering.&nbsp; The discovery of jarosite (formed under acid conditions) at Meridiani and Gusev appeared to support it.&nbsp; This was further developed into the idea that martian water was always acid every where, with suggestions of pH of less than 0.&nbsp; This was supposed to explain the absence of carbonate.&nbsp; We now know at least one place where the pH is in the range of 8-9, which quite alkaline (remember that pH is a log scale, with 7 as neutral, so pH of 9 is 1100 times less acid that 7, and 1000 times less acid that 6).</p><p>4. Martian soil is everywhere uniform.&nbsp; This of course underpins all the paradigms above.&nbsp; It was based on orbital data from Viking and Phobos 2, and apparently supported by ground truth (although the MERs did show some local variation).&nbsp; We now know this is not the case for pH, salinity, and probably oxidation.&nbsp; This does not invalidate the orbital data, what it means that in some parameters measureable from orbit (mineralogy, grainsize) the Martian soil is very uniform.&nbsp;In others, measurable from the ground (pH, salinity, oxidation potential) it is not.&nbsp; On Earth it is similar windblown dust is remarkably uniform on a continental scale and very similar gobally in terms of&nbsp;elemental chemistry and (to some degree) mineralogy.&nbsp; However, the soils that develop on them vary markedly in salinity and pH.</p><p>The caveat to all of this is we are looking at the top few cm of soil.&nbsp; Things may well be different as we go deeper.&nbsp; It would be surprising if they don't.&nbsp; Oxidation potential, pH, salinity could all be different, as they are in terrestrial analogues.&nbsp; It is all very exciting.&nbsp; i dig soil pits on earth and measure the properties.&nbsp; Here we are doing it on Mars.</p><p>cheers!</p><p>Jon</p> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>This is problem that the reports were not well reported.&nbsp; And also this stuff is so new that even the missions scientists probably have not thought of all the implications.&nbsp; they have been so busy collecting and interpretng the data they have bot had as much time to think about the bigger implicatios.&nbsp; Andd unlike us, they don't want to go on record until they have a reasoned argument that will stand up to review.&nbsp; i would be the same in their position <br /> Posted by jonclarke</DIV></p><p>Agreed, and Thank you for that.&nbsp; IMO he coverage of this particular briefing has been relatively good(I realize we have flaws).&nbsp; Headlines and Teasers were what I expected.&nbsp; ABC,CBS,NBC,CNN,FOX,MSNBC etc..

<p><strong>The media proves time and time again in science related subjects that it utterly cannot digest the difference between fact and fiction, between serious scientific&nbsp;debate and Hoaglandic-claptrap, and sadly even&nbsp;confuses&nbsp;the differentiation of 'theory', 'hypothesis', 'speculation', 'faith'&nbsp;and 'bullshit'.</strong>&nbsp; Silylene</p><p>by itself; fine, a punch in my face, I'll duck next time.</p><p>but then the wagons circled:</p><p><strong>I agree with that</strong>. <em>A lost packet</em></p><p><strong>Not too many reporters, even "science" reporters, have the insight to see the significance of this discovery.&nbsp; As such you won't see it in the MSM until everyone online is screaming to the high heavens.</strong> <em>docm</em><br /><br /><strong><font size="1"><strong>I agree with silylene, a full 100% about the fact that the media screw up big time when it comes to reporting science.
