[MOD NOTE: This thread follows on a post by Ed Truthan containing a MAHLI mosaic of MSL wheels taken on sol 275.]
Ed: zooming in on that marvellous underbelly MAHLI montage, there appears to be further (and previously noted) deformation of the wheel surfaces. Damage is most evident in the view of the front-left wheel inner surface. Such wear has previously been discussed and concerns allayed. Nevertheless, the front left wheel surface *appears* to have been punctured. We've only done 700 meters, and have 7000 more to get to Mt Sharp..... Given that more odometry has now accumulated, is any (re-)new(ed) concern valid? DeanM |

chem-cam examination of wheel scratches? first i'm aware of.. a al Gerald's prescient comment.
If there will be some plan to alter course to avoid wheel wear+tear, even though all this not too outside expected parameters and poses no problem at current rates, it raises the question exactly what goal re-routing for smooth sailing would be expected to accomplish? a smoother path probably means it will be covered more with sand and dust and fewer scientifically interesting outcrops to investigate. on the other hand, fewer science-stops could translate to arriving at the entry point or badlands sooner, if that's the point, but perhaps less to tell of the journey there... one wonders what sort of performance the rover will have in soft sands, years from now after most of the soda-can films between the lattices have finally worn and flaked off. I suspect skeletonized wheels could actually be beneficial in a 'purgatory' situation..? |
