Here's a polar view of Tesheiner's pan. I think Opportunity drove to the top of this view. then turned left and is near the 11-o'clock position now (sol 1184).

The azimuth and profile seem about right. I can't imagine what else it could be.

Nice images Stu (as always).
The circular brush marks on the lower image give it a dinosaurian eye. http://library.thinkquest.org/C0128701/Pic...lociraptor3.jpg |

....Here's an animation (from Stu's images).... Strange that just one berry (in the circle) should move so much. I remember in the last moving berry movie, it seemed the movement might be due to sand supporting the berries blowing away and allowing the berries to slip or roll down a slope. But I have a hard time imagining that in this case. And so much movement from one berry in the entire field? |

Wow, LOVE that animation! Would never have spotted that moving berry without it, thanks!
Have made the colour of #2 closer to #1, if that would help someone make a smoother animation...? Just noticed... couple of changes at the top there.... -------------------- |

Is this the first purely wind-moved berry we've seen? There are lots of subtle changes in the soil colour between berries. Here's an updated animation using Stu's new image, with some adjusting of my own, and covering more ground:in the entire field? |

Yeah, I noticed that, too. The appearance of the darkened area at the point of the rock is almost as if water was squeezed out of the rock and flowed out from the tip and onto the ground. Of course, that's not what happened, but it has that appearance. Instead, I next thought that perhaps the RATting of the rock pushed the left edge into the ground and levered the right edge and tip a bit off the ground, resulting in soil disturbances, but I see no other signs of soil disturbance anywhere else along the soil/rock interface. My best guess about that dark patch is that the vibration of the RATting caused the soil to shift a bit, but if that's the case, I would have expected to see other patches of disturbed soil along the soil/rock interface. I think that the berry movement is *probably* wind-related, but I suppose there is a very minute possibility that it was caused by RAT vibrations. However, if the latter were true, I would have expected to see more berries moving. One intriguing possibility is that the single berry that had been sitting on top of the rock, at the RAT site, was energetically ejected from the RAT, flew through the air, impacted the berry that shows significant movement, rolling it down several centimeters. This explains the unusually large movement of that single berry, when none of the other berries have moved significantly -- you'd think that if wind *or* vibration caused that single berry to move, that others would have moved just as much. Hard to imagine a gust of wind that's powerful enough to move that one berry, but not powerful enough to move other, smaller berries elsewhere in the scene. -the other Doug -------------------- The trouble ain't that there is too many fools, but that the lightning ain't distributed right. -Mark Twain

Hello,
As said in THIS post, I'm very late to posting pictures. So, here is Grenada on the Sol 1160 : In the same time, tanks to all who made pictures -------------------- |
