sol 95 OM17 ( tip breaker )montage:

Looks like I can't ignore this cell any longer.

For the third sol in a row this cell has beem imaged. My guess is that there may be quite a lot of "stuff" on this-whatever-it-is that shouldn't be there.

er, make that four consecutive sols for imaging OM17.

Hort,
Isn't this the calibration and tool cell group? AFM tip sharpener, AFM tip breaker etc? Might just mean that they have been using the AM and need to refurbish it. It would not have been used as a sample cell.

Re your 218, are you subtracting the dark image from the UV image to remove stray light effects and hot ccd and reveal the real flourescence? I actually wonder if the sticky polymer in the silicon cell doesn't cover the entire area and this explains the spread stain?

sigh.

OM17 has been reimaged again and again with focus zoom sequences over 4 sols. The last time a cell in this group was imaged on sol 93 a single, sharply focused image was done.

Perhaps you didn't follow the Flickr image links to this EDF ( extended depth of field ) image:

er, an interesting object.

What is it?
What should it look like?
What is the air speed of a fully laden swallow?

( fumble, fumble. where'd I put that damn thing? Oh, here. )

Sol 95 RGB / O / U comparison:

Er, the central image in this montage ( the one labeled "O" ) is the "dark image" and it is clearly "mostly dark" across both the bottom of the cell. In fact, if you look closely you can see that the suspected silicone edges are darker than the bottom -- which means the edges are even brighter.

Perhaps you should ask the Phoenix team to show you their fully corrected, 12 bit uncompressed versions?

reply 224 correction: ...across both the left side and right side of the bottom of the cell...

Is there Any way to tell what COLOR it MIGHT be?? Or is the color in your sol 93 image as good as it gets for now?

Can you explain a little more about the 221 image? its very wierd looking

I cannot work out whatsoever what I am looking at

I think a fully laden Swallow could reach 50 MPH in a dive

NEWSFLASH!

I believe all the raw OMs have been posted to the LPL Phoenix-Home site!

I have downloaded about 300 so far and am up to about sol 21!

It will take me awhile to catch up - but it looks like some pretty exciting stuff!

Hi HOrt

Thanks!!
Looks like it will take a very long time to catch up. From the looks of the few I've scanned, they've been keeping the best wine.

Here are just some of the images

Sol 20

Sol 25

Sol 29

and today's sol 99


Wonder why they have'nt released notes on the context for each of these raw images. Without the context they are far less useful than they could be.

However, Lots of interesting stuff in all of them, particularly sol 20.

sol 99 - the wide pan:

and here is the rest of the 99 stuff.

Winston, we should split up the task of catching up. Sounds like you're working forwards, so I'll work backwards.

Looks like I picked a bad week to start sleeping again.

LWS, Hort and crew. Why do they not tell us what we are looking at? I saw a droplet of liquid. Found out it was silicone. Calibration images. Anymore, I don't know what I'm seeing. As LWS said, no context for the images.

Please and thank you for all the images you can muster up.

As John just mentioned context and colors are confusing, as i can only assemble images from here for now. [link]

this site has INformation and a file code i can use, (Average joe filing system)

what is this Horton? "sol 95 OM17 ( tip breaker )montage:"

working backwards...

sol 44 OM69 ( strong magnet ) "3D" EDF:

with links to full OM69 montage.

I'm always looking for new ways to put the visual information together.

After colorizing the Extended Depth of Field ( EDF ) image from this cell I thought, hey, the EDF algorithm must construct a 3D surface to render the image, so maybe some of that information is in the EDF image. At least it seems that way to me after putting the colorized EDF image next to the color image and crossing my eyes.

There are extremely subtle features visible in this "3D" image. I will not spoil the surprise.

Some OM5 images from sol 33, including a focus movie, a color EDF 3D - and more!

Hi Hort

Please explain to those of us who can't do X-eyed what the subtle features you referred to #234 are. I made an anaglyph but could'nt see and special features except the familiar small spheres which also seem to join together to make up the larger dark conglomerates.

Beautiful images from your OM5 images reply #235.

Re. the Phoenix OM assignment, I'm afraid that I expect to be very busy over the next month or so and can't do much consistently but I'll try as I get time.

Hort, thanks for sharing! any guess what that ring like shape is bottom right? on top of the soil?

HOrt et al

Here is a sol 100 reimaging of OM63. The sample was captured on a strong magnet substrate from dust stirred up at the Phoenix landing. previous images were acquired on sols 9, 11 and 12.

These are all amazing grains!
Hortons Reply 230 might show olivene crystals, maybe a garnet grain or two (maybe the garnets are a trick of light).
The darker and greener grains may be derived from weathered basalt. I wonder what the yellowish material is. Maybe grains evaporite deposits or plagioclase.
There are also colorless clear grains.... these might be quartz grains.

Winston's Reply 239 likely also shows some weathered grains of basalt and magnetic minerals. I also see grains that appear rounded or spherical. These might be magnetic remnants of Martian pyrotechnics like meteorite impacts, micro-meteorites, or maybe even Martian volcanic explosions.
