Thanks Jon, regarding MER communications with Earth.Yes I was aware they used the oribters for relays, but also aware that they have direct to Earth capabilities. What I was not aware of was how much of each method they used. Thank you for clarifying that the Direct to Earth is only a backup procedure. Also yes, that;s one hell of a gamble for Phoenix, to completely remove that capability, seeing as both MO & ME are well into extended missions & that the MRO UHF radio has occassionally shut down (not much I know, but is still a warning shot).Imagine if MO packed up, ME went into safing & the UHF radio on MRO packed up at the same time. Very unlikely I know, but is still possible.  Replying to: <DIV CLASS='Discussion_PostQuote'>It is probably possible, but if the clouds are fast moving the pictures would look bad.  Almost eveeything we an learn from cloud pictures can be learned from B&W images.Jon Posted by jonclarke</DIV>Very true, it would take several seconds for the RGB frames to rotate into position, during which time, the clouds would have moved, so yes the images would have been messy.The B & W ones reveal enough info.Andrew Brown.  <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Given the presence of ice in the soil and the low pressure, I would have expected the water vaour pressure in the soil to be near saturated.Maybe the ground is no colded that no sublimation takes place at all, unless it is exposed to the atmosphere?  Maybe the very cold surface is such an efficient cold trap that when tha atmosphere is saturated it forms frost on the surface and does not prentrate any deeper?When humidity drops the frost sumblimes back into the atmosphere and not into the soil  pores?I would think that this too suggests there is very little salt.  if there were lots of salts in the soil under the current temperatures there would be traces brines forming from these frosts, this moisture might then percolate downwards into the soil before evaporating.But these are questions for a soil physicist or micrometeorologist, not a hairly knucked geologist.At least the public comments on the SDC story are not as moronic those made on the 90-day announcement.Jon  <div class="Discussion_UserSignature"> 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 Arthur Clarke </div>

Bob Clark Posted by exoscientist</DIV>Hi really hope so Bob, that IS being done. Now that the season is changing for Phoenix, environmental readings like those are becoming more important, as are early morning, late afternoon ground imagery, tracking frost development, though that appears to be carried out as a matter of course & rightly so as is twilight, sunset & sunrise observations, for glows & high clouds. Replying to: <DIV CLASS='Discussion_PostQuote'>The problem is mass.  Current MSR missions are looking at 500 grams of payload.  Rocks will be more important than movies.  A  pity in a way, but there it is.  Mind you, if you could pursuade a movie  mogol to part with their ill gotten gains you might be able to fund a rover mission whose sole aim would be to  return high definition TV.  It might be est to start with the Moon first, then go to Mars.Jon Posted by jonclarke</DIV>I can see that Jon, ragrding MSR, but they should still put a decent imager on the lander like those carried by Mars Pathfinder, MERs & Phoenix.

Is there a kind of soil that does not "keep" water.. I know that is not correct English.. but I mean  is there a kind of soil that pushes water molecules awaylike to + + or - - magnets push eachother awaySo water that was ice and becomes gas can't cling to the soil as it is not able to hold on. <div class="Discussion_UserSignature"> </div>

The clouds really got me as well.  I second the motion for higher transmission capacity from mars' satellites.  What is the restricting factor there, power?  Slap a couple of corn plants on there and generate some ethanol (yuk, yuk, yuk). Looking at the clouds really hits home.  You almost expect to see a shadow move by and then a person come into view, or maybe a plane overhead.  I wish we had a couple of minutes of color video of the clouds.  I know NASA is all about the science, but they need to try to pack in some of this PR work into each mission, I don't think they realize the potential impact on the public.  Not sure I ever realized we would see clouds there, and I'm an avid follower of space news. Thanks for all the analysis, guys (gals?).  You are all talking about looking for frost in the photos, can someone circle where you see it or explain what to look for? <div class="Discussion_UserSignature"> </div>

Posted by tampaDreamer</DIV>Hi tampaDreamer. I think Jon Clarke explained as to why it is difficult to get colour video of the clouds. In order to do that, the sky needs to be imaged through Red, Green & Blue filters for EACH colour image. Then do that for maybe, lets say 100 frames. So for 100 frames say, there will need to be 300 images taken. How much will the clouds move between the time for the red filter image to be taken, then the green filter to rotate into place, then take (15 seconds), then for the blue filter to rotatate into place then take (another 15 seconds). During the first colour frame alone (30 seconds), the clouds will have moved. It would look very messy & poor, the second frame likewise, another 15 seconds for the red filter to rotate back into place & take, then so on.A dawn scene would be OK, as the Sun would rise slowly enough for this to not be a real issue & the twilight would not change sufficiently in such a short time to be a problem. Hi All, Sol 97 Holy Cow article.

Replying to: <DIV CLASS='Discussion_PostQuote'>Your girlfriend's camera does not have to operate for years in a dusty near vacuum, while exposed  to high radiation and daily temperature swings of between 50 and 70 degrees.  It has not have the ability to operate in wavelengths beyond human vision. It does not have to be assembled and cleaned to punishing planetary protection standards.  if it fails it can be easily replaced from a shop.Jon Posted by jonclarke</DIV>Well.. last on this topic, as there is more to see and learn there : They can make 19th century black and white photo's have color nowso why would they not be able in the 21th century to change Mars Black and White images into color so we can get an impression of how it is..   <div class="Discussion_UserSignature"> </div>

Just my semi-educated guess, but I think it's the substrate (paper+chemicals) those old pictures were taken on that allows us to eke out the colors.  Whereas a cam like those on space probes are digital right from the sensor plate.  There's nothing but monochrome data. <div class="Discussion_UserSignature"> </div>

Posted by a_lost_packet_</DIV> And those are composites of monochrome pictures at different wavelengths.. If you take just one picture at one wavelength, it still won't be possible to color it, other than by guessing. <div class="Discussion_UserSignature"> </div>
