In rocks' shadow

Sol 170 Mastcam 00:00:04 and 23.59:34. In the shadow of and up against a rock is a thing that looks similiar to a fungus.

On MPJ's latest gigapan there is a much clearer picture of it. Any chance someone could put that up with a more focused picture?

This feature (MastcamR Sol 173)?

Snapshot direct link:

You can always do screenshots while browsing the pans (alt+prntscr - paste into your graphic editor) even in fullscreen-mode.

Thanks MPJ, but that's not it. below is a link to the NASA raw image.

The copy procedure you suggested did not work

On your gigapan it's towards the right hand side, straight up a bit from the inside corner.

In that area this feature imidiatly got my attention - one of the earliest snapshots of that pan:

Yes, that's it.

It doesn't appear to me as part of rock it's up against. (color, shape)Also appears to be on a stem coming up from the ground.

Like to get a closer look at this!

Very interesting.

- round, with hole at center
- 6 or 7 features very similar at the other edge, every 50 or 60 degrees. The 3 at the top in particular look very similar.

Is the image of a Lizard climbing a rock?Scales on the lizard,,distinct?

If NOT,,,then I have found another anomaly.

IF I can figure how to receive the SNAP-SHOT (S),,,in GigaPan,,,,,,,,,,,perhaps it is overloaded will try later.

Here is a screenshot from the pan:

and the according source file:

Also note that nice example of that "blue/green bubble mats" upper right! Smile

Yes I really would wish for some MAHLI close-up observation of this and lots of other features of the YkB area...

Nope ,,,,in order to see Lizard must viewed in giga-pan or else who-doo majik.

Quite the interesting Program,,,the rez is awesome,,,(I have one of the old mac monitors ,,crt,,very satisfying viewing of Mars regolith)

JHD, the links are working. Indeed interesting features you snapshoted.

The semi raw-data (published jpg source files)have been stitched and then processed (white balanced, color tuned, enlarged and sharpened) with Photoshop CS6.

Certain features are snapshoted multiple times by different users - my plan is to collect these and retrieve the real raw data for the most interesting features when available. This should be an eye-opening collection... Smile

Why are the larger smooth rocks predominantly devoid of any "pebbles" that typically surround them? Wouldn't one expect eons of wind to deposit a few pebbles from an ancient stream on the top of a few of these rocks?

Or could they be something other than "pebbles?"

In the closeups of various Mars rovers we have since late 2003 seen many items that could suggest fungi or fungal type objects in a variety of exposure conditions. Regardless of what we were seeing in current mineral or chemical content at present observation, we need to develop techniques for identification and reference. Curiously, I have never gone to the desert to spend time on my hands and knees with a macro-camera, or a microscope used directly on soil and rocks. It seemed excessive and the heat would be torturous. Most of our experience is with a standing or knee elevation common unaided eye view. Even a routine camera cannot be a substitute for the closeups the MER rovers were returning.
The MSL Curiosity is a more 'normal' experience, with cameras at a more routine scale. The MSL MAHLI views, can give better detail than most of us see by unaided eyesight.
Unfortunately, most all life and fossils are smaller than we see by unaided eyesight.
Here is a 2012 research article showing fungal items in cores from sea and ocean sub-seafloor drilling, extracted in vesicles of basalt rock. On Earth, and below waters, buried further, are samples of items similar to what we saw in the 2003-2012 MER images of the Micro Imager camera.
The imaging is low power micro range viewing, more powerful than even the MSL MAHLI can show.
These may aid in identification of Mars items until we have better techniques for viewing Mars rocks processed for closeup viewing at a more appropriate size scale.
Perhaps our future rovers will be successful in extracting drill cores or powder content which can reveal items of this detail, shown only in this decade as available in seafloor solid rocks in vesicles, embedded and buried for tens of millions of years, allowing fossilized reclamation. The polar and temperate realm of Mars, rather than the equatorial realm would aid in mineralization of fossils, with water ice present in quantity.
Will the rover be returned to the 'streambed' location for MAHLI imaging as a test of the preservation of large macro sized objects?
