Sometimes you can see previously unseen ring/s on a windshield of a car where a GPS suction cup was placed some time ago and since long removed.

Perhaps the rings are dirt rings left by sublimating drops of dirty water created by the rockets?

Remember the drops on the legs of Phoenix?

Yes Hort; and the Curi site has commented on relatively large dirt blobs kicked onto curi's deck by the thrusters. Perhaps you're right and this is just portents of things to come. Yah!! Water in the top few cms of the soil. Wow!!

Wonder if they could analyse the organic content of those dirt circles?

The maximum range of the chemcam laser is 7 meters, so, YES, spectra could be done for the sundial dirt rings.

My prediction is it will match the "green" areas in the rocket pits.

DOH!

Looks like the circles are deliberate additions to the sundial!

They are exactly the same size and four are exactly centered on the color chips - and two appear to be random on the grey scale rings?

I'm sure there is some deep reason for their placement.

The fact that SIX particles of dirt landed exactly on the two random circles is incredible beyond belief.

Mars is weird.

Looks like magnets too keep parts of each colour free(?) of dust.

Hort;

You noticed lots of small berry sized spheres in one of the first images returned. The one below shows lots of these spheres, a few possibly rock varnished rocks and a few other interesting objects.

taken from Curi sol 3 releases

I forgot to mention above that what we've seen so far of Gale crater appears to be very promising from the mars life standpoint.

Another one, colour balanced, a crop of a rock with greenish top surface from sol 3 releases.

jj, thanks for solving the mystery of the sundial circles. Yep. Mysterious Martian Magnets.

as your reward, here is my first full frame enhanced difference false color panorama view of several of the skycrane rocket pits:

I will be posting the macro "G+4xd" for this magic in the imagej MER basics topic for all those people ( all 3 of you ) interested in similar processing.

tweaked EDFC ( Enhanced Difference False Color ) of the most interesting rocket pit:

The rocks and soil in the pit are mostly within the 7 meter range of the Chemcam.

The really green small area is 6.32 meters away.

Curiosity may discover "organics" without moving a cm.

Reports say landing was almost perfect 7min 12 sec and 2.4km for the Bulls Eye a trailing wind is thought to have made it fly long into the Elipse. It gives them a chance to traverse an area which perhaps they would not have considered visiting if they landed closer to Mt. Sharp.

Loving the images Hort yes looks like the rocket pits are going to be interesting to investigate once the Brain Transplant has been completed.

Magnets...

raw, tweaked and EDFC ( Enhanced Difference False Color ) of the base of Mt. Sharp:

Does anyone ( rock guys especially ) find any of this processing useful?

It's a lot of work, so if no one finds it useful then I will not post them.

Hort; I was referring to your 212 above. Not your 215.

Why would the magnets keep the area clean? Isn't most of the dust magnetic? Are the magnets set up to be repelling the dust? Why do the dust specks seem to be attracted to the rings of the magnet?

sol 3039 ( Aug 11, 2012 ) raw and EDFC of sundial:

Winston, if you look at Opportunity, the cleanest part of the deck after 3039 sols is around the magnets - especially in the center of the magnet.

The mostly magnetic dust falling near the magnets is attracted to and collected on the magnet - so the area around the magnet is mostly dust free.

I use the area in the center of the magnet as a "white balance" point - and I think JPL does too.

Looks like we now have a really decent (color-) image quality to work with without much artistic interference:

It also looks like - just as I expected from HiRISE coverage - the goodies are well hidden below a layer of thick dust at the Gale Crater floor:

But no color 3D - except with MAHLI. I will miss color 3D.

Hey, MPJ, go easy on that "artistic interference" crap.

Do you believe there is no value to further image processing - like reply 212?

I routinely post-process my images from my digital camera - even when I use the in-camera white balance with a gray card.

Do you understand that the eye is a lousy scientific instrument?

Why do you think there are 16 filter wheels in front of the cameras? How do you plan on viewing the near infrared and UV images?

I can see you are a big NO vote on my reply 215 question.
