Horton, thanks so much for those images (including the location panorama).

To my eye, those folds look like the fossilized remains of stuff growing in clusters on the rock. It also looks there were small streams or rivulets flowing through the breaks in the rock.

Scientists report the robot has been trundling over what they believe to be clay-bearing rocks on the edge of a wide bowl known as Endeavour Crater.

Clays are water-altered minerals, but very different to the ones seen by the rover so far on its travels.

Those previous minerals were in contact with acidic water; clays are formed in the presence of neutral water.

Whenever it says "504 Gateway Time-out" there is no need to post again. I have found that error ALWAYS means the post has been accepted. (Maybe we need a FAQ on posting to the group.)

Barsoomer I agree for some us who have been here a long time we have got used to the quirks associated with this site however we have some new people here and it more than likely causes them confusion. It is good to have more people interacting here so I for one would be keen to try and keep them. We know the site requires software upgrades but this all costs money, Hort has done his best to patch it together and I personally thank him for that.

Kevin, Hort, how much is needed for the upgrades? I wouldn't mind giving $5-$10 for it, maybe if enough people do it you can do the upgrade?

sol 3158 (Dec 11, 2012 ) MI pan of Copper Cliff rock:

with a link to 3D pairs

You really, really should look at the 3D pairs at 200% using StereoPhoto Maker.

There are many "egg shell" features in the 3D. Of course, the rock guys - if they were interested - would say the features are voids where circular "new berries" have fallen out.

And of course, the tiny linear, parallel patterns mean nothing.

Horton, very interesting picture. Could the white streaks be something like snail trails? Also, Does Curiosity have a light on it? All the pictures I have seen have been during the day when I would assume most of the harmful rays would be out. It would be my assumption that any animal(s) be it bit or small would have evolved to be nocturnal animals. Doesn't cur have the capacity to take infrared pictures? She could take pictures at night on a regular basis. Maybe they are and just are not sharing them with us. Thoughts all?

Forgive me, I thought the above photo was from curiosity,,, most of my statement still stands, it probably should have been posted on the Glenleg thread

JCC, if you look at the "white trails" carefully in 3D it is clear that they are mineral filled cracks.

And yes, Curiosity has LED lights ( including UV ) on the arm that can be used with MAHLI - and yes, all the images - including the LED light tests, have been daytime.

Why after 127 sols on a nuclear powered rover NOT ONE night image has been taken is
an utter mystery.

Another mystery is the lack of use of MAHLI for 30 sols.

The Chemcam laser has been banging away during the last month - and - not - one - MAHLI image has been released.

I think I will work on some pancam 3D images this afternoon.

The veins are indicative of a previous fine network of cracks. Note that the cracks have continuations from the rock matrix to smaller rock inclusions within the matrix. That suggests the whole area was subjected to some massive trauma well after the rock had already formed. That might mean these rocks preceded the formation of Endeavour Crater, which could be the traumatic event.

The fluid that formed the veins would then have occurred after the formation of the cracks, therefore presumably after Endeavour was created.

The newberries may have been bubbles, some of which burst, that occurred much earlier, during the time the rock was forming. Many of the newberries seem to be on pedestals; not sure what that tells us.

Opportunity sol 3158-3160 ( Dec 11-13, 2012 ) colorized MI closeup panorama of Copper Cliff rock:

with location and B&W version links.

This is my first "hack" at colorizing the MI, but already there are interesting features.

So many interesting features on that pic Hort. Is the square opening at the top real ?

er, Mauree, the square at the top is missing data. I will redo when the all the data is posted.


However, the triangular wall in this one is very real:

Opportunity sol 3156 ( Dec 9, 2012 ) false color 3D of peculiar fracture fills:


Also, thereare some unusual minerals in this area:

Opportunity sol 3161 ( Dec 14, 2012 ) enhanced difference false color infrared / visible 3D of peculiar minerals:

The bright yellow / bright yellow material should be examined with all the filters and the APXS.

In Horton's reply 155 top image, it looks like the rock had a hard outside, leaving the fins, and a soft inside, just like the newberries. The inside seems Whitewater-like.

I wonder if the hard outside has packed newberries like Kirkwood? There are a lot more images of this rock in today's pancams at the Exploratorium.

By the way, I find putting just a "&" at the end of the web address and reloading (and maybe repeating this step) often brings out posts that have not appeared yet. It also often enables typing into the text boxes for a new post. Also, refreshing this page, or the immediate "back" page and then returning, often enables typing.

Holly smokes, that colourized closeup of Copper Cliff is amazing! Geologists will be struggling with interpretations for years. What I hope they try to find is a clean contact/unconformity with any of the surrounding units, which would help with the interpretation.

Definitely worth a 200% tour using StereoPhoto Maker.

How does nature make triangular rock walls?
