Tricky to line up the two RAC images but here is my attempt.

Greg : it's parallel, not crossed eyes (or maybe I ever made a confusion... huh.gif ).

Ants,

When I copied and pasted your image into Stereo Photo Maker (as a side by side stereo image) and swapped the left and right images, the cross eyed 3d effect was perfect. BTW what is parallel? Aren't the images left and right as taken by the stereo camera? But hey, I'm not an expert, just learning from them.

parallel is when you focus behind the images, cross-eye is when you focus in front of the images. I always found it easier to do cross-eyes, have a hard time making myself focus at infinity when there's a computer screen just in front of my nose..

Beyond a certain point, it's impossible to do parallel. Cross-eyes works pretty much no matter how much displacement there is between the two images.

Looks like a small dry powdery deposit of some sort to me - ice isn't whiter than white like that.

Can it be silica?

This was discussed in yesterdays press conference, and the answer is that silica would be completely unexpected in this environment.

At a recent press conference one of the panel thought it was unlikely to be silica based on the geological context (no evidence for volcanism or geothermal activity at the Phoenix site). I'd add that, apart from a few white bits in the first scoop, there's no sign that the white stuff was moved around by the scoop, and I'd expect a powder to get easily redistributed in the trench by the scoop. As far as the brightness, it's hard to say - on our planet, ice can vary quite a bit in its brightness. It's worth keeping in mind that the albedo of Martian soil is typically quite low (really it should be called brown rather than orange), so ice could apear much brighter than the soil.

Here's quick look at the sol 11 "Baby Bear" scoop, from the images that are down so far.

I can understand that viewpoint, but on the other hand, wasnt the silica that was discovered by MER
completely unexpected there too ? laugh.gif

Only until they found it.

What are you comparing - same filter, different times, or same time, different filters? Can make a big difference.

Ahhh - Your correct, it's just a filter change. I should have looked at the time stamps first. It had the looks
of a depression left by sublimed ice. The white area must be overexposed giving it the appearance that the
depression is filled.
