It is an anomaly for sure. If it is dust then why does it not disperse? If it is magnetic dust why does it move so freely on the metal surface? Because it moves so freely, why is it still there?

I was thinking about what I said on the other thread. Life on this world is an extension of the geologic environment. We are walking bags of salt water liken to the oceans. I suppose following that thought, life on Mars would have no choice but to be liken to dust.

To quote the great science officer of the star ship Enterprise, “Fascinating.”

Thank you for the running time of 11 days. This 'organism' shrinks and grows as we can see in your posted image. Our Fred may be on to something-other than colored dust or simply the deck uncovered by winds at will. An elegant theory proposed Fred...fascinating indeed, gentlemen!

...and this particular portion on the deck may be either the warmest or the coldest spot making it the most comfortable situation it has ever been in so this 'growth movement' is reality.

Any comments out there!

Hort and anyone with the time. I remember seeing some dark material on the Phoenix Lander deck. If someone could look back. I am at work. Looks like another Blizzard this week. Warnings go out for NW Minnesota at 4:30 EST.

I think this is it,
left image ( right eye ) was taken on sol 41

************

note: I fixed the link to this sol 39 image that I thought at the time showed "frosted" soil in the shadows. I think I showed later that it was simply a lighting artifact - but I could be wrong.

Here are all the Phoenix photos taged with soil and deck.

The stain seems to have consolidated its recent gains. Note the elevated bits are no longer peeking through; the depth must now be sufficient to cover them.

> ... there are no full size all filter pancam images of the deck.

Sol 294 comes pretty close:

R1, R2, R5, R7 and L2, L5, L7 in full-frame EDRs.

(There are two sets of R1,R2,R5,R7; the earlier ones cover more of the area of interest.)

Also full-frame L4,L5,L6 on Sol 2228 with L2,L7 as down-sampled bonus.

On sol 1390, full-frame R1 and L2,L5,L7.

Sol 927: full L2,L5, L7 and sampled L6.

Sol 882: full L2,L5,L7

These are other full-frame images that include the area where the stain is now. The 2228 images, of course, include the early stain.

The above is an image posted by Winston as reply 299 in the "On the Road Again" Vol 5 thread. I thought it was worth reviewing now.

The color of the dark soil area just above the sundial in the image is a close match to the stain in the L2, L5, L7 filters, as pointed out by Winston. It is from Sol 2161 and interestingly is also pointed to in the SS reply. The dark area seems "rotted" rather than wind-eroded.

In the above image, the top row shows the clean deck on Sol 2, while the bottom row shows the stain area on Sol 2161.

The left column shows the images through the L2 filter, whereas the right column is through the L7 filter.

Note the clean deck looks darker in the L7 filter, but the stain is darker in the L2 filter. Thus, the signature of the stain is quite different from that of the clean deck.

(BTW, "not entirely convinced of not X" is not quite the same thing as "believes X")

sol 2454-2462 sharpened L257 animation of changes:

with a link to a saturated false color montage of the two images.

The image processing has amplified the JPG artifacts and added GIF artifacts but I think there are hints of color and texture changes as well as shape changes to the stain.

sol 2453-2454 ( Dec 18-19, 2010 ) sharpened and averaged views of the stain:

This image is the average of three registered and sharpened L257 images. I am encouraged that the resulting details might be "real" as the "TWO WORLDS" text at the bottom of the sundial is almost readable. But if the fine details are "real" then what are all the "squiggly" features in the rock behind the sundial???

Maybe it's best just to close your eyes and repeat three times "they are are not real", "they are are not real", "they are are not real".

Don't you feel better now?

The right eye view looks like the stain has widened a bit at the left edge both at the top and at the bottom.

Yes, it seems to be getting bigger. Anyone still think this is a "deck cleaning"? ( Steve??? )

Stereo x-eye view of the Sol 2468 stain in Horton's #76. I now think the stain is essentially flat throughout and that the apparent piling up near the wires is an optical illusion.

What I don't understand, though, is the apparent light-colored barrier (pointed to by the red arrow) that seems to bound the stain to the right. It looks elevated, but does not correspond to any of the fittings on the deck. Maybe it is a micro-ripple?

The lettering of the "Two Worlds..." legend on the sundial seems to be getting clearer even in the raw images, especially in the visible light filters. Does this indicate a kind of cleaning? The rover power does not seem to have increased, but maybe it is poorly angled in relation to the sun while positioned at the crater.

Today's stereo image of the stain. From this slightly different angle, it looks like the stain might be climbing the light-toned dust around the wire.

The stain seems to have preferences. It seems to preferentially spread to areas

(1) that had light-toned dust,

(2) that are near to elevated areas on the rover deck, like the platform, and the wiring near the solar panel.

There are other parts of the rover deck that meet these conditions, but it seems it can only spread by extension, i.e., to places adjacent to existing stain areas.
