sol 3074 ( Sep 16, 2012 ) 3D of stain re-emerging towards the back of the rover:

Yep. definitely gravity related.

Looks like the stain is moving down under the edge of the sundial platform.

This looks different---kind of cloudy.

I haven't commented on this thread before, but I have to admit that a mobile stain may lie somewhere in between extraordinary physics and insanity.

The "horseshoe" stain. The material in the stain is looking more and more like dark soil compared to the original extremely flat texture. (Definitely not a cleaning now!) I think the dark material of the stain has darkened and coagulated some of the original light dust.

In popular science fiction, such as structure, there is a creature that is called a horta.

The horta is a Silicon based life form that is in essence a 'living rock'.

http://en.wikipedia.org/wiki/Horta_(Star_Trek)

If the mobile stain is an alien form of life, then one possibility could be that of a 'Silicon based' life form.

As such, it would in fact be "just rocks".

A rare full-resolution pancam view of the whole stain area. Only a right eye, though.

Here's an interesting article to read:

Quote:

"NASA has discovered a new life form, a bacteria called GFAJ-1 that is unlike anything currently living in planet Earth. It's capable of using arsenic to build its DNA, RNA, proteins, and cell membranes. This changes everything. Updated"

"NASA is saying that this is 'life as we do not know it'."

marsman,

old news, and it turns out, wrong news. Followon studies showed it doesn't use arsenic in it's DNA

Glenn,

I did another check on the web and I agree with your assessment, with regards to the arsenic claim.

hhw and Barsoomer,

I have no clue as to what the mobile stain really is. Maybe I can suggest something that is a bit more outlandish such as a mobile colonial microorganism. A volvox is an example of such a thing on Earth, but it lives in water.

I think

This could not be a result from winds that blowing around
This could not be a result from frost/thaw processes
This could not be a result from mechanical viberations on the deck
This could not be dust movements from temperature changes
This could not be natural behavior from dust laying around
This could not be...et cetera

I think this could be a sign of life forms which is doing its business.

Notice the sharpness of the stain edge.

Fascinating! The soil behind the deck looks particularly stain-like also.

Er, how are the new spots on the solar cell related to the old stain?

It would be interesting to see if the new spots change size and/or move around, too.

From Reply 635:

"how are the new spots on the solar cell related to the old stain?"

Maybe they are related to the old stain via sporing or budding? Confused

Seems very obvious that there is more moisture on the rover

I think the difference between the two Sols in Horton's animation is that dust has been removed, giving a sharper view of the dark deposits that have resulted from previous stain episodes.

Barsoomer, you could be correct.

The dust factor from the last few status reports:

3110 .619
3116 .601
3124 .604
3131 .606
3136 .612
3145 .608
3151 .599
3158 .590

where 1.000 is perfectly clean of dust.

There was a change of 0.008 between 3124 and 3136

However it has gotten dustier since then ( and tau has also increased ) so the next view of the spots should be interesting.

BTW, the earliest dust report I could find was Dec 19, 2007 ( sol 1382-1388 ) which reported a dust factor of 0.8
