Wow! The great pumpkin is a great berry producer! <br /><br />Sorry I've been out of the loop for a while, do they still think the berries were caused by water? What would cause the great pumpkin to obviously be producing these spheres? It seems it's an ongoing process or they would be covered by dust. <br /><br />Mars is very alive...at least it's rocks are!<br />

Here is an image of that again with some question on what we are looking at. It looks like some<br /> kind of a aqueous solution, maybe highly acidic, flowed out that area??? <br /><br />I keep reminding myself about the density of the atmosphere there, Triple point of water <br />etc, etc. Some chemical process appears to be still flowing on Mars. If you mixed in a highly <br />soluble compound in water such as sulfur what would happen to its triple point? There is some <br />yellow sulfur looking substance on the great Pumpkin. The color of the flat area seems to <br />suggest that it washed off of the berries. <div class="Discussion_UserSignature"> Ron Bennett </div>

It looks like “One great leap for something kind.” <br /><br />A lot of the rocks appear to be hollowed out; I wonder if one of the rocks next to it that was <br />turned over was attached at one time?<br /> <div class="Discussion_UserSignature"> Ron Bennett </div>

<font color="orange">"It has been proposed that a 39% sulfuric acid solution would be a stable liquid on Mars’ <br />surface today (Clark, 1994)." <font color="white"><br /><br />Thanks I didn’t know about that, I knew about the brine but not the sulfuric acid. If you <br />couple that with a CO2 atmosphere what would happen, 1.5 times more dense than <br />a comparable NO atmosphere? I was at a Mars society conference several years ago where <br />one of the presentations was on the triple point of water in a CO2 environment and how <br />it would be different than is in a NO environment. The person that presented his findings <br />showed where NASA did some investigations after he approached them on it, I don’t know <br />what became of the research. The percentage sulfuric acid may be lower than that if you <br />factor in the CO2 atmosphere. Some Extremophiles on earth feed on sulfur rich environments.<br /><br />There is also some yellowish substance in the dunes that I couldn’t filter out; I would like to <br />see the spectra analysis on the image below. Here is a darker look at what appears to be a <br />sulfur pool area on top of the rock.<br /></font></font> <div class="Discussion_UserSignature"> Ron Bennett </div>

Comparing two images of the sundial you get a good idea how much dust Spirit has accumulated so far.

<font color="orange">This rock combines features from Razorback and Escher, plus it has berries !<font color="white"><br /><br />Looking for the spectra from Razorback and Escher. It is big enough for the rat, big enough to retain <br />heat at night and I hope they thoroughly examine with the alpha particle X-ray spectrometer <br />instrument. <br /><br />Look below at what was just released on 10/07/04 on Spirits Ebenezer and Clovis.<br />Notice the amount of SOv3 and Cl is very high, sodium trioxide, a strong reactive oxidizing <br />substance, solid melts at 40C, ? What happens to SOv3 in a CO2 atmospheric environment at <br />1/100 of the density of earths. SOv3 is an anhydride of surfuric acid and sulfates are a <br />byproduct. Just add water. <br /><br /><font color="yellow">Data on this graph from the alpha particle X-ray spectrometer instrument on the robotic <br />arm of NASA's Mars Exploration Rover Spirit reveal the elemental chemistry of two rocks, <br />"Ebenezer" and "Clovis," in the "Columbia Hills." Scientists found, through comparison <br />of the rocks' chemistry, that Ebenezer and Clovis have very different compositions from the <br />rocks on the Gusev plains.<br /><br /><font color="orange">My guess is that after it is heavily studied it will become an eye-opener for geological <br />procedures inside Endurance.<font color="white"><br /><br />I agree, I hope they don’t pass up the “Opportunity” to explore it.<br /></font></font></font></font></font> <div class="Discussion_UserSignature"> Ron Bennett </div>

Here is what I got for spirit sol264 and oppy sol256. Notice the spirit sundial difference of the true <br />blue color below the top surface that doesn't have as much dust on it and the dusty surface coating view. <br /><br />Every monitor is going to view these sundials a little differently because every monitor isn't <br />calibrated relative to each other. <div class="Discussion_UserSignature"> Ron Bennett </div>

It is next to impossible to use image comparisons to estimate dust collection. First of all, <br />it would be important to use images taken using the same filter. Judging from the differences <br />in the color patches, it looks like different filters were used in your two images. Then there <br />is the problem of variation in exposure. Note the difference in the darkness of the shadow <br />and background in the two images. <br />All these differences make it impossible to determine any change due to dust. <br /><br />It doesn't look like dust will be what does the rovers in anyway (unless there's a dust storm). <br />The solar panels have done so well providing power, even in the dead of winter, that with <br />spring on the way, the power situation will only get better in spite of any dust accumulation. <div class="Discussion_UserSignature"> </div>

<font color="orange">Centsworth_II- The solar panels have done so well providing power, even in the dead of winter, that with <br />spring on the way, the power situation will only get better in spite of any dust accumulation. <font color="white"><br /><br />True, if they stay stagnant then the dust will accumulate even more. The best way to clear the <br />dust off the solar panels as soon as there is more light, is to drive full speed over the <br />Martian terrain, the vibrations from the rover wheels rolling over rocks will get rid a lot of<br /> the dust. Even though the rovers top speed is somewhere at 3 Kilometer per hour,<br /> because of the .38 gravitational field compared to Earths, when it hits a rock it gets more<br /> airborne. <br /><br />Spirit right now has a twisted ankle so they can't drive it at full speed once there done on <br />that part of the hill. The rovers have lasted a lot longer than most people imagined, they <br />keep going and going - like that energizer bunny.<br /><br /><br />2P150255017EFFL6M12 <br /></font></font> <div class="Discussion_UserSignature"> Ron Bennett </div>
