Regarding the WHITE in reply 135:

One can see larger WHITE areas on and around the bolder in Reply 109.

I also noticed BLACK and other colors (reddish, greenish)in some patches on rocks and the soil.
Some rocks seem to be covered with strange layers of "something".

Now that MAHLI has demonstrated that it is capable of producing sharp, well focused images of excellent quality, do you think the general public will be getting some of those images for run of the mill rocks, shells, etc.

On sol 66 we again had some ordinary MAHLI images of disturbed soil that had some very interesting looking objects but which were as usual lacking the resolution MAHLI is capable of.

A further alteration of the same image noting the crinoid like shapes and the fiber arcing to the multiple sheets of elevated material appearing related. Every MAHLI image has content which could statistically show a pattern of information.
.

.

In the #137 image from MPJ, the shadowed layers are very close in the foreground. The channel is very obvious and more than wind could produce. The single bright layer of two larger rocks, one foreground, and the ledge at mid-range, is very out of normal for the scene.
The bright item looks cylindrical and manufactured for sure.
A small impact is clear, but not confusing beside the channel path.
Are they unsure of traveling further?

Altered for color balance, exposure.

Ref., #143,
The incidental line of terrain change leading towards the bright item may give a indication it is an in place object, despite manufactured appearance. Other objects are as bright in the scene, but they are angular and irregular in shape.
Why have they not used the ccam to view it closeup?

I'd really like to see a MAHLI hi res image of the soil in the scoop this sol 67 image.

Dana when I clicked onto your second pic in your "reply 143" I got all sorts of garbage on my Mac and had all sorts of trouble shutting down and restarting my safari. NEVER AGAIN!

Example for some BLACK coating in this image a little bit left/up from the center:

This and the WHITE coatings are definitively not debris from the rover or decent stage.
There are too many and they are on the rocks and look like coatings and not like debris.

Winston, I agree the MAHLI is a real positive surprise of the MSL hardware! Smile

They did a nice closeup of a very bright pebble in the scoop area which I wondered already in previous images. As this pebble appears bright white in all images as of yet I don't think its a specular reflection but the real color (lower left):

So what may it be? The scooped area looks interesting at all... Smile

Testing again. &refresh didn't work for me.

I saw it and thought it was a specular reflection but looking at it again, it does'nt. Could be debris but doesn't look like plastic this time. This MAHLI image is very suggestive to me of a damp earth soil with lots of microbial activity going on. Am looking forward to the analytical results.

You need to do &refresh twice. It works the second time, but not the first.

much more BLACK in this image:

one rock a bit to the lower-left of the center is completely black in the lower half of the rock. This looks like a coating. Any suggestions from the geologists? For me it looks really, really strange.

Appears to be issuing from the soil as Kye suggested, but is the material a Mars type, or manufactured as it appears?
Time for closeups and testing at least with the laser?

The filled fracture or dike type rock across the channel bottom should be a source of interest to the MSL group as the color changes in the area of the crossing and the fill is eroded by something there.

A great opportunity for chemistry testing the laser system? Two targets in short range, and there they have the rover in place.

These images are in PNG, should be the standard for older Macs. Color block may be showing as a false positive for the Mac security software also. Seriously altered colors from low contrast images can produce the effect you see in these if saturation is increased as here. Sometimes it is referred to as color block.
My security software again shows nothing here, nor on Image Shack.

Horton. Again all the posts from #22 to #26 have been removed from your server updating of pages. They were readable, but are gone now. They are still listed as by number at the Forum section, in more than my name as posting person, so it is not found here as a problem. That has always been the case over the eight years of the blog problems.

My reference in #153 was to the topic 'Exploration of Gale Crater-part two',
[link]

The Forum shows John's entry of #26, with no content showing. This is an attack on topics, by someone at the blog. The topic page two isn't even accessible by selecting the archive button, or Forum icons.

Barsoomer; Tried the (& refresh x2) Still doesn't work. Looks like the only thing that will solve this problem is Hort's return in a few days

I'm back - but working on reducing the 1784 pictures I shot on the trip to a reasonable number ( like 600-800 ).

I e-mailed Mark about the missing page link problem for the Glenelg topic.

The pages are there - just the links are screwed up - but just for this topic. All the others seem OK.

Hopefully, it is an easy fix.

MPJ, Barsoomer;

I would really like to see the image below captured by MAHLI at the same fine resolution as the plastic images. The image is very busy for a subsurface that has no interaction with water in a sterile environment.

http://lws.smugmug.com/Other/MSL-Curiosity/i-qHFKBgM/0/X3/0067MH0079000014R0DXXX-autoWB-X3.png

Some of the objects may be a result of pixellation, but I don't think all are.

Winston, the MAHLI close-ups of the scoop areas doesn't look like some inactive/sterile moon type regolith at all. Maybe some NASA scientists will have their Eureka effect "discovering" the plenty of Earth examples of chemoautotrophic microbes active in almost any kinds of soil and rock on Earth and the implications for life on Mars...

Still curiously waiting for SAM/Chemin results of this kind of Martian soil! Smile

This is one of the sol 66 MAHLI images enlarged to 2x at dpi 2347. If your computer shows a blur or locks up you have your browser settings to show images at the fixed dpi at full size as default. That would require you reduce the zoom scale or download the image, at 220K file size to see it in a image editor or browser or Win image viewer.
The PNG shows two bright items in one of the initial scoop gesture's. I think these were not seen later possibly as they appear here to be the same as other bright items, but seem to have differing shapes than those on the surface in sol 67 imaging.
These are devoid as are former tiny very dark items of 'dust' or reddish colored coating material. A very dark item appears on the right of the lower conical apparent shape as well. Precisely where are they scooping, as we were looking at the bright channel item, after the plastic, I believe, then the plastic item, now scooping.
What is the proximity of all the bright items in several days viewing and scooping?

Size 2x, dpi 2347 MAHLI

A 1 to 1 view of the scene. This is 'auto' color adjusted, then levels adjusted for brightness in shade.
.

.
JPG altered for color balance, shadow compensation. MAHLI size 1 to 1

Is the brighter zone actually the former seen dike or filled fracture in the channel?
Can the alteration be that great as to make a soil rather than a solid rock structure?

Has the larger bright item ever been touched as yet? It was rather large in appearance from the mcam images viewpoint.

It also appeared possibly tubular, whereas the upper small item in the MAHLI enlargement here looks tubular as well.
