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

Something I first noticed today - it seems like the back wheels (relative to the rover) did a lot of the driving to get the rover out of the trench.
This is from looking at the panorama posted by jvandriel in this thread, and a high res color picture posted by dilo in this thread. Now, granted, I don't happen to have a full scale rover model here to take for a test drive, but it just looks like the back wheels did an awful lot of pushing here. The churned middle of the tracks almost goes right up to the level of the rest of the dune. Note in that color picture though, the middle wheel's track. Compressed, and scuffed slightly (tread marks aren't readily visible), but definitely not scraped like the main tracks. The navcam panorama shows a deep impression right where the front wheels were. It looks like they just flat out dug in for a little while, until they gained solid footing. Whether or not that compressed dirt that follows was crushed by the rover, or if that's the duricrust, I'm not sure. I wonder that it is the duricrust (duracrust is it?), since there are some "flecks" of it behind where the front wheels sat, as though it broke some off and turned it under the wheels as they sought solid ground. Again, just some more random thoughts on the tracks. |
