All of the raw images from all of Curiosity's cameras are uploaded here before they are processed.
"Space is big. Really big. You just won't believe how vastly, hugely, mind-boggingly big it is. I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space." - The Hitch-Hikers Guide to the Galaxy - Douglas Adams 1952 - 2001
I noticed some dents and dings in the wheels... seems a bit soon for them to be showing wear doesn't it?
After you said that I went looking and see what you're talking about. One thing that came to mind is Curiosity is much much heavier than previous rovers, such as Spirit and Opportunity. So the Martian gravity is taking its toll as the rover rolls over jagged rocks and gravel.
My religion is the Universe. So much is unknown, yet you can see it in plain view. If you need an explanation on why life might choose not to contact us, Google "zoo hypothesis"!
