Just had a good look at the self-portrait and am a little disturbed by the large number of dents on the wheels. I know its been commented on and dismissed just after landing but we have only gone 400m and they look a little battered. Its especially visible on the center port wheel in the Hi-res in this picture. We dont see that kind of wear on Opportunity and its gone 35km. Are they really up to the job, MSL could well go 50km, will the wheels fall off before then???

It's just cosmetic; as long as the main structure is intact they're not gonna impact driving, very much. This is a heavy rover; it stands to reason that even small rocks will leave dents.

No - they will be absolutely fine. They'll be dented and dinged and have holes in them...and they're carry on working just fine.

The mission team has said that it is likely that they will find more flotsam from the rover and EDL event.
Not inconceivable that these are more of the same.

The entire surface is amazing of course, not just the bright bits wink.gif

When you look carefully at some sky images taken on Sol 86, some bright pixels are visible...
Any ideas by some astronomers on the Forum ? Stars ? Planets ? "Schmurtzes" ?...

Very nice, looks like olivine in the third one.

Looks like a pan of the sky at five o'clock at night and they appear to be in the same place on different photos.

Image chip pixels can fail in at least two ways-- including go black or go white. So you can have black or white "Schmurtzes"

A cosmetic blemish visible in a flat image need not be a pixel that has "failed". I haven't looked in detail at the stuff on the detector (schmutz)--some may be only partially opaque, and thus correctable. Hungry4info is right about the bright spots--they are mostly hot pixels. There could be some cosmic- (or RTG-) rays, but I didn't see any obvious ones. Hot pixels may be unrecoverable, when the generate signal so fast that they saturate almost any useful exposure. But most are fine, just something to calibrate. And most of the ones shown get lost in images of high-entropy scenes.

Color from the raw Mast camera images. Perhaps too much green.
