[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 think that it's safe to say that the admin/mod team has decided to keep this thread open since over time more holes will appear, and hopefully it will function as a place for people to find answers (esp. those new to UMSF), which have been graciously provided by members such as mcaplinger.
However, alarmism will not be viewed favorably, nor will criticism of the project team or designers. Engineering is all about compromise. We could have had massive wheels impervious in all respects to anything, but probably would have had to lose one or more instruments, and/or change something in the EDL methodology, and/or, and/or...it tends to snowball. The wheel design is highly robust & survivable, and it's the best compromise that could be derived based on overall system performance requirements. Enough said. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
