Man...she is dusty!!! Really struck by the accumulation on just the one side of the omni antenna mast. One result of this might just be the need to drag a grounding strap like many cars in the southwestern deserts of the US do to prevent occupant shocks when debarking, but in this case it would be to make rovers less electrostatically attractive...
 ...even though the wheels are metallic, it still seems like adhesion is a major problem after a storm like that.Might be productive to do a dust deposition survey (insofar as that can be done) on Oppy to look for regions that might have been particularly prone to accumulation for future engineering efforts. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE (jvandriel @ Oct 7 2007, 10:04 PM)  Here is the complete view inside Victoria Crater. Dilo, stitched with Autostitch and as you can see, no problems. I see, very nice! I made a polar and two "vertical" projections from your panorama (top right projection is approxmately aligned with rover vertical, bottom one was rotated in order to have a simulated view of the rover from rear/side):

They both already have several ultrathin tungsten needles fitted to bleed-off electric charges into the atmosphere.

Based on jvandriel's stitch, here's an artist's enhanced view of the Sol1313-14 panorama.
Enjoy Astro0

Stu.
Great rathole at post 178. The tiny 'stalked' concretions at the far left really bring home to me what 38% gravity and an atmosphere that is a near vacuum really means. |

Inspired by dilo's polar projections, here's a little artwork I'm calling 'The Little Prince'.

I have "hit the wall" trying to use the pancam sky-flat images to correct for the dust. I have been using the L1 filter to correct the image after RGB conversion. Here is my final attempt at the north view:

I have been using the L1 filter to correct the image after RGB conversion. I don't know how useful this is as I play a few tricks deep within my processing software, but this is my input flat-field:
I gave up using the sky-flats as well, the stretching does bad things I think. This is made from some fairly featureless ground pointing pancams in L1 from sol 1290 stacked and blurred. Properly used it should account for vignetting as well. James -------------------- |

The MI cought some particles moving in a gust of wind on sol 1320.
