I was browsing some raw images and came across this one... looks like the damage to the rover's wheels is worse than they've lead on so far!

How all this mess is possible after ONLY one year over there?
It seems to me that are mad of an aluminum FOIL... do they made some test here on earth BEFORE sending the rover?
Mars gravity is also weaker than here on earth, so I cannot realize how such damage could have been formed!




Continuing this way, I think the rover has very few chances to continue *real science* down there!!!

Yeah I'm with you Mario, those wheels are a mess, and it's only been 1 year under Mars gravity - surely they tested those things on Earth first? It might have been a good idea to put at least a little rubber on the tyres, ultra thin aluminium on rock is a pretty dumb idea even if you're not a rocket-scientist.

It seems hard to post images on this page, yours didn't work and neither did mine.

Here are some links to some of the wheel pics (if they work):

Ciao Dylan
Yes, I just re-adjusted the links and it seems to work now.
Anyway, your images are the very same as mine, even not even worse, since your first link points to an image where the aluminum dent is bent right angle to the center, which freaks me to hopefully not cut the motor wires Shocked Confused
Which is a even more terrific situation.
I wonder: why re- invent... the wheel?
why not use the very same wheel has been used on Oppy or Spirit?
This makes me also think that Curiosity has an RTG generator on his back, which could give power for dozen of years... OMG why throw all this to then bin making wheels made of paper mache?
The misteries of financial programs?

flexes,,, thin someone somewhere goofed.
Will I ever get over it? hard to say. Looks bad right now.

Time to start planning for a crutch is NOW!

Exploration into soft/hard IO ware needs to
start ASAP,,, Five wheel Driving,,,Arm Placement For,, any others come to mind?

I wonder if Curiosity has the ability to perform 'laser surgery' on itself? It sure would be an interesting use for the chemcam Very Happy

...searching on the tube, it seems that thay almost did it... on purpose! Confused
I'm sure that the rover Curiosity could also on squared wheels, even if the copertone will be completely ripped off... but WHY on earth, make it so weak... ?
