<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>this is the mac daddy thesis statement: " Actually, I think it's a hypersensitive, almost paralyzing caution; classic fear of ostracism and it's consequent detrimental effects upon one's scientific reputation, which can have negative effects upon acceptance for publication, grants and attainment of tenured positions...... making what might be seen professionally as an extreme claim tantamount to career suicide." this is exactly why experts seem continually vague about many of their official press releases. they have become politically adept at saying a lot of mumblemouthing and prattling on about nothing. you can read a recent release and you have not really come off from it knowing any more than before you read the report. spacedaily.com is full of such breaking news reports that really don't say much. i mean, all of them are not b.s. by any means or even vague, but a good many, too many, are. the thing is, this image on this page or above is so absolutely obvious to me, and i am an idiot layperson. it is blaringly clear and i don't know why they don't or didn't examine that further with the rovers. why?!! they were right there!! why didn't the @$%@%% rover dig a little trech over and analyze it?!! they go millions of miles and they just roll away from it?!! "follow the water" is starting to be like crying wolf. i am snoring and bored with their apparent aloofness and disaffected attitude. if they did dig there and i do not know, then pardon me. but if they did not, then.... well. i can't say what i want to on here. calli will be all over me. <br /> Posted by bonzelite</DIV></p><p>I can't say that I'm not a skeptic of a lot of what goes on in astronomy theory, but the Mars missions (all planetary missions) seem like great science from my perspective.&nbsp; I don't think any of us understand all the details that go into planning and executing these missions, nor do I understand all the reasons they don't do things I might personally like to see them do, but I'm always impressed with these real science missions. &nbsp; Even if they were to discover that there is no water and no life on Mars, we will still have learned something in that process.&nbsp; I'm more than willing to give NASA and other agencies the time and funding they need to research this issue and other planetary issues because they are interesting and they do tell us about the universe around us.</p><p>I tend to agree with Jon that you're missing the idea when they are saying follow the water.&nbsp; They're simply looking in the most likely places where they might find water and doing it on seriously hamstrung budget that has many other "priorities".&nbsp; As skeptical as I might be toward some beliefs in astronomy, I'm quite satisified with how my tax dollars are allocated as it relates to Mars and learning about it's environment, and I'm impressed with the scientific informoation these missions return.&nbsp;&nbsp;&nbsp;</p><p>As it relates the informaion we gather, anything we learn is useful.&nbsp; Learning that something isn't there can be just as important as learning that it does exist there.&nbsp;&nbsp; </p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>

Thanks rlb2 for posting the fantastic images.&nbsp; I'm trying to catch up on this thread, but what I've read and seen thus far has been very enlightening.&nbsp; It will be interesting to see how the Martian year has an effect on the equipment.&nbsp; I wonder if we'll get to see it snow on Mars? :) <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>

<p><font size="4"><span style="font-family:Verdana"><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'><span style="color:#ff6600">Hello rlb2,My guess is that salts in the soil, probably highly concentrated salts in the soil,&nbsp;dissolve&nbsp;into the liquid water surface layer on the ice crystal surfaces during the Martian winter.&nbsp; Then when the ice sublimes away in the Martian spring, the salts crystallize out.&nbsp;&nbsp;This gradually forms clumps and adhesions between dust and soil particles.In fact, in the scoop of soil, you can see chunks of white something, which my guess are highly concentrated salts.&nbsp; In fact, I would not be at all surprised if the white material uncovered under the lander is actually a layer of rather hard salt crust, just below the looser soil.&nbsp; I think that the annual cycles of ice forming and subliming would concentrate the salts, and ultimately exclude the salts from the bulk ices&nbsp;to form a salt crust.&nbsp;&nbsp; Maybe the salt crust is only a couple cm thick (?).......... The clumpiness and crustiness should have been expected and predicted from a soil that goes through annual cycles of ice deposition and sublimation.&nbsp; In fact, these cycles could be duplicated rather easily in the lab, and this would be a good exploratory study to see the effects on soil clumping and salt transport. <br />Posted by silylene</span></DIV></span></font></p><p><font size="4"><span style="font-family:Verdana"><span style="font-size:13.5pt;font-family:Verdana"><span style="font-size:13.5pt;font-family:Verdana">Hi <span style="color:#003399">silylene</span>,&nbsp;Sounds about right to me, sounds like you did a little research on this, soon we may find out what it is. They claimed to be a little miffed about what it&nbsp;is that is causing it, that&rsquo;s a good thing it allows me to speculate even more.&nbsp;I would go one step further and guess that some of the clumping is from more&nbsp;water mixed with soil than they expected as they scooped it up.&nbsp;</span></span></span></font></p><font size="4"><span style="font-family:Verdana"><span style="font-size:13.5pt;font-family:Verdana"><span style="font-size:13.5pt;font-family:Verdana"><span style="font-size:13.5pt;font-family:Verdana">I would speculate that water vapor is seeping out of the surface at certain times of the day and it is clumping more&nbsp;during the warmest time of the day.&nbsp;</span></span></span></span></font> <p><font size="4"><span style="font-family:Verdana">It wouldn't take too much pressure from the soil above water-ice to turn to a liquid if it had a heat source and as you said mix that with salts and you have a brine. The temperature above the surface may be -22 during the day which can be warm enough for a slurry of brine to exist underneath the soil, but the surface temperature of the soil maybe 20 degrees or more warmer. It is much colder above the surface in the day time than on the surface on mars because of the thin atmosphere and the absorption of the suns energy, Viking, Pathfinder found that out. </span></font></p><p><font size="4"><span style="font-family:Verdana">Take a walk on the pavement outside sometimes barefoot in the summertime on earth. If it has a dark </span><span style="font-family:Verdana">Albedo then it will absorb more radiant energy and be much hotter. </span><span style="font-family:Verdana">&nbsp;</span><span style="font-family:Verdana">Heck even water may exist as a solid or liquid off and on like it does in the tundra areas of Alaska under the soil, in this case the top layer of soil provides the added pressure that traps the water vapor building up even more pressure to allow it to turn into a liquid underneath the soil.&nbsp;</span><span style="font-family:Verdana">&nbsp;</span></font></p><p><font size="4"><span style="font-family:Verdana">Phoenix may be sitting in a mud trap. It will be interesting to see the landing pads as the days goes on if they sink into a muck like during a warmer part of the day, just like you would expect in the Alaska tundra. That would be a kick to see before the end of its mission.</span></font></p><p><font size="4"><span style="font-family:Verdana"><span style="font-size:13.5pt;font-family:Verdana">Another possibility is electrostatic cling.

<p>Might these movement type patterns also be caused by small changes in refraction of different wavelengths due to moisture in the soil?</p><p>I like the way you're thinking by the way.&nbsp; I'm also wondering if the various wavelengths and different image times might be influenced by some sort of prism effect in water molecules in these same regions.&nbsp; If this is some sort of tundra condition, I'm wondering if excess moisture in these areas might not have a similar effect?&nbsp;</p> <div class="Discussion_UserSignature"> It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. - Kristian Birkeland </div>
