QUOTE (sattrackpro @ Apr 8 2006, 07:50 AM)  For those that can devine it from the info available, is today (Saturday here) a drive day, or is it another one of those every-other-day non-drive days? If I'm interpreting the pancam data tracking site correctly, the usual suspects are there for a drive on sol 805: CODE 805 p1301.09 2 0 0 2 0 4 penultimate_rear_hazcam_pri_17
805 p1301.09 2 0 0 2 0 4 penultimate_rear_hazcam_pri_17 805 p1311.03 2 0 0 2 0 4 ultimate_rear_hazcam_pri_15 805 p1311.03 2 0 0 2 0 4 ultimate_rear_hazcam_pri_15 -------------------- --O'Dave

QUOTE (dilo @ Apr 8 2006, 12:32 PM) Look at this strange, thin white track! (Sol804, two right NavCam stitch) I suspect that the white material is temporarely trapped inside a wheel, then slowly released while moving... Not only is the white trail interesting, but notice how the wheel drags through sand only in some regions. In others it seems to just scrape over a crustier surface, while just below the midway point on your mosaic the dead wheel apparently lifted completely off the ground for a short distance - all I can see are the treads from the right rear wheel! I imagine this is due to the topography. |

Yeah, Dilo, either that or a chunk of the sulfate salt (like that big one at lower right) is being pushed ahead of the stuck wheel and gradually abraded. If we get stuck around here for the winter, this system would allow us to play the first games of tic-tac-toe on another planet! How cool is that!  .

That is it. Look at the shadow-enhanced FHazcam from Sol 803 and the salt is clearly in the wheel. And look at the image you posted, the sand is very thin over the sulfate in places, so some of that line may be exposed salts.

Very good catch, Bill (as usual!
 ).In fact, looking to past Front HazCam pictures, it seems that blocked wheel collected a huge amount of sulfates in it's interior especially during Sol799 (see image), then redistributed it during next days thanks to movement vibrations...
(hey Shaka, we have a HomePlate so if we design a diamond we could play to baseball!!  ).

Shopping for a Dry Line Marker? - Compare Prices:
 Jumbo "100" Dry Line Marker by Stackhouse - $316.15 "Spirit" Sulfate Dispenser by JPL $400,000,000 (approx)Good seeing, Bill, and thanks to dilo for that great comedic line! Here's to hoping the solar power umpires call Spirit "safe" soon... -------------------- Lyford Rome

Sol 805 driving was executed, adding some 8-9m to Spirit's odometry.
Here is my guesstimation for the rover's position after this move:

I don't get it... where are they heading? "Mitchelltree ridgeline"? ("Low Ridge Haven") then where?
Can someone take a guess on the proposed route Spirit will take. |

The small hill you can see in that navcam mosaic above? I think they're heading for the northern part of that (just beyond the right edge of the slope we can see)

The above pictures looks like that Spirit is heading toward west since the northern part from Spirit must be the "El Dorado" which is not on the visibility of that picture? However, the "Mitchelltree ridgeline" is northen part of HP, but the northern view must see some hills. Rodolfo |

They're travelling west, to get on the northern slope of the small features to the south of HP

Does anyone still try to tell the time of day on Mars with the sundials
on the rovers? What luck have you had with it? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Hello!
I've made this view from four pancam images taken through L2, L5, L7 filters.  (1944 x 1995px) We can see the "trench" (or the canali in refering to Shiparelli ) make by the right front wheel.It's hard to meet McCool... Good luck Spirit
