Here's a gimp enhancement of the flows in my replies 1159 and 1160

Here's another example of the "erupting" subsurface from sol 1201.

This one gives a better indication of the different chemistries in the subsurface through the boost chromaticity function in Gimp

AZ-Dave; Re your reply 1149

Here's a minimal X-eyed 3D made from a sol 1106 and a sol 1110 image.

It seems to suggest that the white spots are solid. But not overwhelmingly so!

Some navCam images were posted today that should have resolved the question of the pale tracks left by rocks moving on the Curi deck. There are so many of the tracks on the sol 1185 deck that there should be no question but that they are obviously tracks.

But look at the below 3D anaglyph.

To me the pale tracks seem to appear solid throughout most of their length. But that is impossible. Right?

Probably an optical illusion.

I also noticed (but intentionally didnt mention) the fact that Curi's tracks dont appear to traverse that "rock" that appears to have a flow up and around it. I was going to study a few more images, but I cant see where the tracks touch...indeed, someone at mission control needs to recognize the potential threat if nothing else, and try to ensure safe routes...I suspect they see this happening, and have probably adopted the idea that it "just happens" but the events are probably not deep enough to be a problem...maybe...maybe not.

Nice X-eye image, very clearly shows the upward movement.

I noted this "shiny" rock a few days ago, thought it might just be angle of sun, but the rest of the rocks are all dull/flat...

I wonder if we are looking at ice/wetted rock, or iron meteor lodged between the other debris.

I think we are looking at pale coloured veins in both the foreground and the background rocks. The background examples with the glint resemble several rocks with small surficial veins in a number of images by Curi with no evidence of reflective iron meteor surfaces.

Noticed that some people have been looking at an old sol 135 image I'd posted here that showed some "growths" on a rock at yellowknife bay. I've redone the image and its below.

AZ-Dave, I think the glints in your reply 1167 might be caused by something similar what is shown in the above image.

Here's what I think is a very revealing image that must merit some rethinking of the official position on the environmental conditions on Mars surface. It is a crop from a sol 1197 image of a piece of equipment on Curiosity. The image was auto white balanced, magnified by 1.5X and sharpened by unsharp mask in Gimp.

Here is the result;

I wonder what produced the stains and significant weathering and deterioration of the nylon bag? It certainly couldn't be water. Or could it?

Nice re-post from SOL 135. That certainly looks like lichen...or similar.

On the Curi Images, Ive also noticed how the staining appears to only affect some parts of the rover, while other parts are still brilliant white without even dust...we may be seeing static-related dust, and then if the ATM is actually much higher than officially reported, relative humidity will do the rest Smile

re. the sol 135 post. I don't think it is a martian lichen. I think it involves life but not as a lichen type. I have some other images on my smugmug photo site that shows the structure much better from two chem cam images.

LWS: I took the liberty to lok over all your images today at your web page. Ive seen many of these images before, but never compiled them together. Also - I find the "color" images they provide to be like looking at mustard spread over everything - basically washed out pictures. Ive adjusted contrast and saturation on some images, but ive been concerned it might be unintentionally enhancing things that the human eye wouldnt really be seeing. I think the image you have that shows the following tells the real story, and that is the colors they present, AND the contrast levels are hideous and misleading as to the true nature of the scenes, and I can no longer say that enhancing or adjusting color/saturation/hue/contrast is unacceptable. I just dont have a perfect solution for what the human eye would see "in person" using the degraded (and possibly altered/smudged) images the public is provided:

https://lyallsmall.smugmug.com/Other/MSL-Curiosity/i-T3rQcfS/A

https://lyallsmall.smugmug.com/Other/MSL-Curiosity/i-BLbbnfv/A

The metal parts of the rover are GREY not greenish, and as you show on the left, GREY is correct, so I tend to agree with most of your minimally-adjusted processing (white balancing?) - Kudos! Smile

If those images dont relay the color tampering going on with official released images, nothing will.

I must say, there is compelling evidence for multiple wet-soil areas, even mud flowing up thru drilled holes, as well as numerous biological targets, and when a person sits and looks at everything compiled, it becomes ever more compelling.

LWS - i noticed one of my sentences above got misplaced - concerning the Hideous contrast levels - I was referring to the "official" "true" color images JPL keeps providing...

Just wanted to clear that up.

AZ-Dave;

You had me a little worried there at first! But I re-read it and realised what you meant.

For a long time now I've been white balancing the official images to try to get a reproducible presentation of contrast and definition for the features in the NASA images that I was interested in exploring, such as hints of dampness, signs of microbial growth, etc.

More recently I found that auto-equalizing the images that showed slope streaks or what I call "debris flows" made them stand out significantly from the normal official monochrome colours so I've been continuing to use that transformation on such images.

NASA uses an auto white balancing algorithm themselves, particularly when they want to show panoramas or when they use the MAHLI camera to take horizon shots and label them as what the human eye would see on Mars. Presumably most of their images are not what the human eye would see.

Anyhow, I'm happy that at least one person appreciates what I've been doing and that perhaps recognizes that the features that I've been trying to point out might be real and not the figment of an unrealistic fantasy.

Thanks.

Winston

AZ-Dave

Its a very interesting thing, how Many MAHLI images have very different sky tones (as well as ground and rover parts) that MASTCAm does...same day, almost same area, MastCam is "Mono-Mustard" while MAHLI shows blue horizons, different sand colors etc.

Maybe part of their problem, is that different sets of processing teams are either processing RAW data differently. -Or- The "Raw" data they receive isnt really Raw, and has already been "squashed".

Recent images of Dunes are a great example...in some images you cannot make out the ripples, slides and slumps - few images later, and you not only can see all of it, but there are literally different color layers of those sand dunes...

Given that there is no global or regional Dust storms on Mars, and because we know from Orbital Images, that the atmosphere on Mars is fairly easy to see through, we also know that the Sky should not be extraordinarily bright, nor orange...(actually at 6mb the sky should be virtually black)...so why would the Grey metal parts on Curi be tinted dirty green? - They should appear virtually the same, yet dimmer, color as we would see on earth. This, along with the severely contrast-reduced images tells me there are still major distortions taking place on the official images.

What process/program do you use to "Auto" balance your images? And do you use the horrible "color" images they provide, or only the un-bayered versions?

thank you again -

AZ-Dave

Caption: "The scene is presented with a color adjustment that approximates white balancing, to resemble how the sand would appear under daytime lighting conditions on Earth." - link: http://mars.nasa.gov/msl/multimedia/images/?ImageID=7626&NewsInfo=59C884BFF2B8E0EFC1D701B94F94BA55AC4A8F96030078DBC14E50FCAFD5D997C48FDFD8F6DEC554C74091E4DCFC81779B89C2488A0457

Really? a White Sky, Grey sand, and Grey Rocks? I thought the rocks were ORANGE or REDish in color?

They cant agree on Anything can they...I will go find another official white balanced image very close by where the SAME rocks are Orange...so...Which is it JPL/MSS/NASA? You CANT have it BOTH (or all 4 or 5) ways!

Caption: "A color adjustment has been made approximating a white balance, so that rocks and sand appear approximately as they would appear under Earth's sunlit sky" - link: http://mars.nasa.gov/msl/multimedia/images/?ImageID=7627&NewsInfo=59C884BFF2B8E0EFC1D701B94F94BA55AC4A8F96030078DBC14E50FCAFD5D997C48FDFD8F6DEC554C74091E4DCFC81779B89C2488A0457

Orange Rocks??? - SAME Image, zoomed out. Ahhh...yes...same processing indeed. Wrong!

Or how about this one: Looking toward the dunes (note baby blue sky & Dark Dunes)


Caption: "The scene is presented with a color adjustment that approximates white balancing, to resemble how the rocks and sand would appear under daytime lighting conditions on Earth"
I can go on and on, but the point is, that images being released literally DAYS apart, with supposedly the exact same white-balancing adjustments, reveal Dramatically DIFFERENT Sand, Rock, and Sky Colors.

Lets see what they give us after todays 90 meter drive, in the coming days: http://mars.nasa.gov/msl/news/whatsnew/index.cfm?FuseAction=ShowNews&NewsID=1882

Here's a new sol 1214 image crop that shows a very interesting debris flow. This one shows a recrystallized white salt along with some other debris.

perchlorate anyone?

Either that or some sort of wet chemistry has beaded up and ran across the dusty rover top in just some areas? Help me with this Shocked
