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

Great image ! I don't understand though that they dare to move around this "quick sand" just like that ! I thought that driving oppy from now on would take ages.....It doesn't ! (which I like with respect to moving on, but on the other hand i'm afraid history repeats...

(which I like with respect to moving on, but on the other hand i'm afraid history repeats...  just a thought: from this image it seems that the danger of digging in could be "simply" a function of the slope/steepness of the dune flanks (rather than soil composition differences) ... Oppy crossed the "flatter" dune in the foreground several times with no problems. The Flank of the "bad" dune (Purgatory) seems to get considerably steeper just where the wheels started to dig in (of course this could also be an optical illusion effect from the differnt perspective of the image) |

The steeper, the rover needs greater velocity to overcome it. It is supposed that the rover has no accelerations but at slow and constant speed. Driving on sand dunes is very alike to flying. The pilot must know on where, when and how much is to accelerate or deaccelerate according to the slope pending, height and kind of sand. The case of Oppys, it must look for a less steep slope and a pavement martian land. Rodolfo |
