This event deserves its own thread.
To quote the illustrious Dr. King -- "Free at last, free at last, thank God Almighty, we're free at last! So, how much y'all want to bet we'll stay here for a few sols, looking very carefully at the tracks and waiting for the MER Team to figure out how to proceed from here? -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Yes im fully aware this is all part of the somewhat roundabout turning around to Purgatory.
My post was to suggest they might be on the lookout for possible egress routes at the same time, and since its firm sand it looks good to me at least. ![]() |

OK all you thinkers, this is a hard question that i am wrestling with for days now:
I am completely puzzled ![]() Could it simply be the influence of thickness of the loose material on the evaporite layer underneath, that is thicker on the dunes (so it can move sidewards more easily) and thinner in between, the latter being compressed mostly downwards, so the underlayment does most of the support ? |

QUOTE (Marcel @ Jun 17 2005, 09:01 AM) My guess ![]() It all depends on the angle over the dune, along with the size and the particular geometry of the dune that would determine whether the rover would start the vicious circle of digging into it as described above. |

I think that's it, there is nothing special about the mechanical properties of this dune. They have been getting gradually higher for some time. If you look back to sol439 where Oppy almost did an unintended 3 point turn it looks like it was on the verge of digging in there. It sailed off course because its right hand wheels were draging and the wheels ruts are quite deep. It just needed a few more degrees of slope for the inevitable to happen. The point is that it did not seriously endanger Oppy just wasted 10% of its entire time on Mars so far, something that we can't afford to happen too often. Richard |
