Their's movement at the station

Hi,

Seems the "Rock Pool" with the tracks has something happening with objects on the floor of the pool moving around, some disppearing and some appearing.

First checkout this image from Sol 137:

The 9 Sols later on Sol 146:

Two of the new objects in the Sol 146 photo have dark patches just below them and one new object is in the middle of the lowest track. The group of objects at the left extreme end of the right most rock shadow (Sol 146 photo) have been rearranged.

It would appear that more of the Sol 137 object can be seen. IE, it appears they are less submerged.

Hi MicroKid,
Very interesting. The most obvious difference to me is the apearance of a sphrical object on 2nd image at 10 o'clock near the center. Also If you are referring to the tracks appearing in the mod, What do you think they are tracks of? Rolling spherules? Why aren't they present at the end of the track?

Hi A1,

I suggest the "Tracks" are moisture welling up from under the soil and/or maybe doing a short run from under the overhanging rock.

I have made a multi-image (13 images) from the Sol 146 photos. The sequence covers 337 seconds (~6.5 minutes) and shows some of the "tracks" do look like flow pathways, yet others look like semi connected dark patches.

As for the BB and their arrangements, they don't seem to be directly related to the "tracks" yet they are there.

If anybody has a web site, I can send the the 13 photos as an exe file so they can post it and we all can flip between the images.

Hi Ian,

Looking at the Front Haz cam shots from Sol 145, the "tracks" are probably the result of dislodged and rolling BBs as the rover is working above and to the side of the "Rock Pool" on a 20 deg slope:

Looks like the big BB landed with a "Thud" and dug up some of the darker soil under the surface. The others entered the patch via the lower darker trail with some others bounching off the rock face to the right and continuing down (up in the photo) the crater.

The long dark non connected patches probably show the path of other bounching BB.

Interesting anyway.

Rerrangement of spherules and apperance of the new one(s) are most interesting. I prepared this image with contrast stretch to show additional traces. I think also the dark tones are sign of moisture. Actually the dark area having apperance of shadow of spherules would be actually preserved wet area by the shadow of spherules keeping the soil cool.

This image is in temporary location, could be
availabe for a short time.

MicroKid, email the .exe file to me. I'll put it up on gtse.net/mars12.htm

What a find, Micorkid!

There are numerous differences in 9 sols: Not only did the tracks appear, but several, um, rocks, are rearranged -- and one blueberry seems to have appeared from nowhere! ( no trail -- but it may have dropped off the rock above it.)

I might mention the best way to examine this stereo pair is use StereoPhoto Maker.

You can make adjustments to the positioning,size. rotatopn, gamma as you compare different sections of the image.

This particular pair is a compromise to show the overall changes.

You will have to sort out and ignore shadow differences.

IMO, the geometry (in particular the curves)of the traces as shown in Reply 0 is not consistent with the upward welling or trickling of water. When I think of the upward welling of water, I think of water seeping through cracks from rocks underneath to form damp regions in the soil.

When water trickles, it meanders down sandy soil. There is no evidence of meandering in the traces as shown in Reply 0. Instead, the traces form very regular nonrandom straight and curving paths.

I am going to see if I can make and post a before and after animated gif for this and use the images that were taken with the same camera filter for comparison.

Did'nt NASA destry this fossil with thier fossil irradication tool?

I love the fact that the berry appears out of nowhere!!

Can someone find the "missing berry" in the earlier photo?

This thread should be in the general forum! More people would see it there. I saw it because I was getting bored with the other fora. forums. forae.

MicroKid, email the .exe file to me. I'll put it up on gtse.net/mars12.htm

Done.

You know, seeing dynamics is a fascinating thing. For all the creature hunters on this blog, I'm surprised we're not going nuts on this sequence.

Here's some ideas to shoot down.

1. Ratting the nearby rocks shot junk all over the place resulting in the changes seen.

Objections: possible to leave debris, i.e. new objects, but trails of rolling debris should terminate in the objects that rolled.

2. Upwelling near surface water resulted in the curved trails.

Objections: Temperatures are dropping, this would be the time where near surface brines would be more prone to freezing than upwelling. Similarly, water diffusion through semi-permiable materials should have a more poisson distribution than a curve-linear distribution. It should be blobs, not lines.

3. The surface subsided resulting in displacement of materials and curve-linear dark regions along the subsidence tracks.

Objections: I like this one.

4. A small undulating critter, snail, worm, snake, wandered along the tracks lightly displacing the soil along its path.

Objections: There's not supposed to be any critters on Mars for the last few billion years.

OK, whatcha all think?

Hello MicroKid,

I did not receive the mail. Hmmm resend to : gtse.net@comcast.net

Just a note to give you a heads up!!
I am moving this thread to the open forum for two reasons.
1)To get more people involved in this discussion.
2)I see no clear biological claim.

I think what we are seeing is an effect produced by the wind.
