[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 |

I'm trying to get a handle on wheel geography in order to interpret the survey images and look for changes. These are all from the sol 513 MAHLI imaging. I count 20 inter-tread areas (where the punctures are forming) between treads. Because the Morse code makes such a good landmark, I am counting upward and downward from those spots to name the inter-tread areas, 10 up and 10 down. I'm noting locations of tears and punctures as they are closer to the rover (medial) or farther from the rover (lateral) or in between (central). So far I've just looked at the right-side wheels. Here's what I've found in this one set, keeping in mind that the RF wheel was incompletely surveyed. There were some spots I wasn't sure about. Now I need to complete the survey on the left side, and then compare back in time to try to note any others that I missed on this survey, and to try to put some constraints on when the tears initialized and worsened.
RF 6 down - big puncture, center RM 5 down - small tear, center 9 down - big puncture, medial 10 down - small tear, medial 6 up - small tear, center RR - nothing major -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
