Um, if you look at the raw pics at nasa, you can see lots more missing pixels than that.

All it is, is a missing pixel. Big freaking deal. What do you think it is, a UFO? NOES, teh Martian's will break teh Spirit.

Ah, now we know the reasons for all the troubles earliers, those sneaky Martians!

actually, it's not a missing pixel,
it's a pissing mixel, a native creature of Mars ! On the picture you can clearly see how it approaches the rover and prepares for a hot shower from above !!!! Disgusting little bastards......

1 Megapixel
Wow, that is cool.

I can't wait until NASA digital camera technology filters down to us consumers!! :D:D

A Sony DSC-F717, with a street price of around $600, has 5.2 million sensors (or 5 megapixels) on a chip that is 8.8 by 6.6 millimeters (or .35 by .26 inches). The Pancam has just a million sensors spread across a chip that's 12 by 12 millimeters -- nearly a half-inch square.

Each tiny Pancam sensor, measured in microns, is nearly four times as big as those on the Sony.

In the consumer market, which Dalsa does not target, 5-megapixel cameras often use the same size CCD as a 3-megapixel camera. More pixels are simply crammed onto the same-size chip.

"The pixels themselves get smaller," Myles said. "This has an impact on image quality."

Why? For one thing, smaller pixels are less light-sensitive.

Also, the lens quality might not support the additional pixels. As the receptors get smaller, a higher quality lens is needed to properly focus light onto each pixel. So where each pixel ought to capture different light information -- say perhaps a subtle shading change on the subject's cheek -- the same information can get spread across several pixels after passing through a lower quality lens.

That is really interesting ........ Kinda puts the whole "MP = MHz" thing into perspective.

lol :)

Anyway, yes, the other rover, the Opportunity, is currently rolling around the flat highlands of Mars. The landing was spectacular.

<a target=new class=ftalternatingbarlinklarge href="http://marsrovers.jpl.nasa.gov/spotlight/spirit/a12_20040128.html"> Revealing Mars? True Colors
</a> from marsrovers.jpl.nasa.gov, on the second page is info about the large blank boxes.


Picture with black dot over mountain, looks like they have 3 pixels gone bad. That one over the 1/3 from the right and 1/3 the way down, also 2 others in the upper left that are together.
