Notice the stretched wire between cells here. Maybe this is what broke?

sol 105 OM36 ( slicone):

More weirdness.

This sample cell has bothered me since the very first image on sol 74. In fact, I didn't post it because I didn't know what to say about it. I have a few comments in the Flickr comments - but basically it still doesn't compute for me.

Maybe someone else sees something different?

Barsoomer, I like your idea some part of the
sample cell broke. That should be obvious when it's imaged. Saaay, there was a nanobucket cell imaged on 105. I will process that one next.

Hi Hort

re. your #278. I was'nt referring in the first part of my post at #275 to the "wire thingie" at all. I was referring to the Barsoomer discussion on tardigrades and pointing out that the very first OM published had captured an object that looked very much like a dessicated tardigrade.

Re. the "wire thingie" I dont think it is metallic because it is partially transparent. It looks too featureless to be a nematode but who knows what the martian coditions would do to a nematode. Nematodes can be transparent and I suspect some of them fluoresce. It's the first time I have seen an object like it in the phoenix OMs.

Mystery solved.

If you go to the Phoenix site and blow up an image of the tell-tale you will see some fuzzies. Looks like some material has blown off and landed on the OM.

PS: Do not tell the boys at UMSF

Thats a very good working, testable theory, Fred.

I'm kind'a whacked out right now, but I will see what I can see tomorrow.

I wonder if the conditions that spawned the 2 dust devils ( maybe more!) were severe enough to damage the lander - including the telltale?

I actually looked for images of the telltale around the time of the twisters, but didn't find any obvious ones. There seemed to be some real gusts later that sol.

The maddening thing about the LPL "system" of disorganization is that time-order is the order received on Earth...

Wait. I just remembered that the Lemmon's SSI site is ordered much better. Perhaps you can check out his site between 1:30 and 2:00 on sol 104?

AhhHHH. never mind. The first one was taken at 2:06

Gott'a rest, gott'a rest.

I just read the official notice for the dust-devils observation and realized that I can't read hex dumps very well any more! ( I use a hexdump program to read the metadata in the JPG files )

The actual times for the dust devils images were mid morning 11:53:00 and later NOT 1:53:00

Of course, the telltale times stop at 11:05:52 - but that last one is a flyin'.

I really, really, need to slow down.

Here's another sol 105 composite showing some interesting particloes and groupings of particles. Hope they can look at some of these more closely.

horton has made avery good cross veiwing image of an OM. it is taken on different sols, but some of the grains have moved just enough to give some good 3d.

i think i see a cube, along with some very good grains.

Is jarosite a possibility? in the mixture?

I will try to post some crops of the good 3d areas. Any more created yet horton?

Hello OM image enthusiast.
I'm a long time Mars data armature researcher and have be looking at some of the microscope photos and found it interesting that some of the pebbles very nicely colored pebbles seem to be moving or just move, from one photo tell the next photo is taken.
I've made some GIF animations that show this happening on Sol-103.
This is my link to the three animations.

Hi Woodlock

Thanks for showing your very beautiful OM images. They are truly well processed. Re. movement of the particles, I think that, especially on the magnetic substrates, the movement of the Optical stage causes some of the particles to be dislodged and that is what you have captured.

Thanks Winston

A resent soil sample no doubt.
set 6,
OM 45,
strong magnet,
After rummaging through the data some more. Wink Cool Very Happy

Let it be said that this test would not be a wrong test for finding life of which the possibility of finding is not been proven to be totally unlikely. Very Happy

Welcome aboard, Woodlock.

It always makes me happy to know another pair of eyes connected to an imaginative mind are looking at the OMs.

Er, mann, I have about 120 old OM's ( mostly colored, some gifs, a few montages ) that I haven't yet posted to Flickr.

The job of documenting them even to the point of cell types and positions seems just too daunting right now. The older ones that I have posted have received very few looks ( 10 - 20 views ) vs 100s of views for the new ones.

Plus I am very tired now. I think I am fighting some virus ( headache, fatigue, a slight fever and nausea ) and I really need to just rest.

If anyone has a particular OM image from an old sol I will post it - but right now...

Peculiar sponge-like mass in Sol 110 OM image.
Hope Horton can work his usual magic on this one.

sol 110 OM39:

er, Winston - or anyone else interested -- could you cross check the sample cell for me?

I am really surprised. I think that this is the same sample cell OM39 where the ribbon thingie was located:

Er, where'd it go? Did it fall out? make babies? I am sooo confused...

Also imaged on sol 105.

Super fantastic images.

Looks like there might be an OM basis as well for the use of the OFB.

Yes! The first sol 110 image was indeed OM39 strong magnet.

Yes! The second sol 110 image was indeed OM 35, weak magnet.

I am beginning to think that the magnetic properties of the substrate might be secondary to an inaccurate delivery process for the soil OM samples.

Anyhow we have both strong and weak magnets showing on sol 110 the same type of beautiful ORGANIC like structures in the soil samples. Those objects look like they have opened and revealed numerous spore like bodies inside. Now I know that Brian will insist that they ARE definitely some well known earth mineral but I am sticking to my story.

Could those structures have been there before but were not visible because of inadequate focusing? Or could it be that sol 110 has some peculiar environmental properties triggered the opening of the soil particles which from early on showed some underlying spherical structures? Or could it be that the dust devil(s) deposited the thread on the OM and then removed it and also deposited these organic looking spore type analogues on the OM fairly indiscriminately?

What is the security status of the individual OM stages? It seems as if many are being reused but could it be that more than one circular stage is exposed to significant new contamination from unintended samples and dust blown in by the wind whenever the OM stage is opened for deposition of samples?

Re. the apparent movement / disappearance of the Thread since sol 105. perhaps the AFM tip or movement of the stage dislodged it.


THings are progressing!

and to the right of OM37:

Both first imaged ( at least by me )on sol 105

Hi Hort

Here's a detail from your sol 110, OM39 image above. I've tried to sharpen some of the features without magnification. I used Dana's recommended software xnview, which looks pretty good and easy to use.

Re your reply 298 above. That seems to be strengthening my point about the inaccurate placement of the samples on the stage. Despite this they are getting some excellent fairly evenly distributed sample sizes that are OK for viewing without significant swamping of details.

That is indeed the image of the year from Hort. I posted a copy in the Who section with a few arrows.
