[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 |

Yeah, and any pause to inspect the wheels is clearly at least briefly harmful to the goal of getting to Mt. Sharp as soon as possible, but hopefully in the grand scheme of things it is a miniscule one, so I'm not going to change my subtitle for this thread....yet.
I was thinking about how to harness the powers of this forum for good when it comes to the wheels. One question I often have when I see wheel photos is: are those new holes? Or are they old holes? If they are old, are they bigger than they used to be? I made myself a map of the wheels and was thinking about trying to note precisely where and when specific tears and holes were first noticed, hoping to use it to check subsequent wheel images to see if holes are new ones or old ones but it's a bigger job than I have time for. Maybe the attached PDF/PNG map of the wheels would be of some use to people...? wheel_tread_map.pdf ( 1.53MB ) Number of downloads: 1039 -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
