Hort; Re your reply #39. I can't help but think that those small dark spheres in the image totally resemble spore bodies. It's not all dust.

Is Curi doing anything to look at an indepth chemical analysis of such sites? I note that they are very similar surface bodies at the current sites imaged today.

If they are following up such indications of past or even present biology I have absolutely no quarrel with them delaying the trip to Mount Sharp. After all a bird in the hand ........

I actually don't mind Curi stopping to smell the roses... This place especially looks very interesting...
I wish the rock guys could explain the splendid feautures in the latest pics

Sol 0324 MAHLI enhanced difference false color of rock:

with location link.

Rock eaters? SOD? - or just funny patterns in the dust? Inquiring minds want to know.

And also from sol 0324:

Run away! Run away!!

A curiosity morality play:

This image is labeled sol 0324 with a time stamp of 2013-07-04 20:10:01

and this almost identical sol 323 image has a time stamp of 2013-07-04-4:01:09.

Apparently sometimes the sol and times are the onboard processing times of the image - and not the image acquisition times. ( the instruments all have their own local storage! )

Also, the Chemcam sol directories don't indicate the dates on which they were taken. For example, these sol 321 images seem to have been taken on sol 319?

It's hard enough trying to establish a time line with all the different file naming conventions - but this is DUMB - not to mention confusing.

The IMPORTANT time is when the image was taken.

Another example of excessive complexity when simplicity would have been easily achieved.

white balanced images of the past week or so are increasingly showing up blue surfaces along with the numerous microspheres. I wonder if the Chem cam results are showing increased Mn which might indicate rock varnish? Anyone knows?

Sol 0326 colorized chemcam panorama of rock:

with location links.

Why this rock and not one of the other 100s of rocks within 7 meters? I think there is a lot of happenstance in this mission.

Sol 0324 MAHLI EDF synthetic 3D false color of dark mineral on rock:

I really hate the MAHLI synthetic 3D images but this one shows the dark material is on slopes of every orientation so most likely is not wind blown but is eroding out of the rock - or perhaps coating the eroding rock?

And here is an interesting chemcap view of some distant tilted layered rocks:

with location link.

Why is the chemcam being used as a telephoto camera rather than the Mastcam-100???

I've taken the liberty of autoWhite balancing your reply #48 3D image above and magnifying it by two. The result is below

Seems to me that the surface shows some very interesting dark microspheres that closely resemble fruiting bodies. In addition the blue coating with numerous bumps and holes also suggests pycnidia like objects.

Drive 56 completed: climbing 2m (6ft), and driving almost 40m (130ft) in under 37 minutes. New location is approximately 10m south of 'Bathurst Inlet' where they examined 'Cowles' on sol 54 with the Alpha Particle X-Ray Spectrometer (APXS).

Sol 0327 MAHLI distant view of Gale:


Sol 0327 Chemcam panorama of distant Gale vista:

er, what?

The cameras designed for the closest work are being used to photograph the most distant vistas?

I don't think the Chemcam panorama is located within the MAHLI image - but I might be wrong.

To complete the silliness, here is the latest closeup view ( sol 0318 ) of the ground from the MARDI camera:

which. of course, was designed for entry and descent.

Hey, I hope they start using MAHLI over the Mastcam as it is a superior camera.

What is the black stuff / and black rocks on #51? Volcanic origin ?

Sol 0317 enhanced difference animation of Phobos and clouds in the overhead sky:

Are the bright points stars? - or hot pixels??

Phobos is quite bright ( -5 magnitude ) but I simply don't know whether the exposures were long enough to record any stars.

IF the points are stars then they would have moved about 8 degrees during the 34 minute sequence - and there is NO apparent movement of any of the points. But it is possible the navcam was programmed to track the stars.

A couple of companion left images would have been useful.

I think there really were overhead clouds that thinned during the sequence.

Hort; I disagree with you re. the MARDI image in your reply #52 above. Your enhancement of the image is indeed excellent and it also shows colours and small objects that might have been beyond the capabilities of the Mastcam.

e.g., Where the Curi wheel has broken some rocks and exposed the undersurface there is a hint of the microchannel being formed of small pebbles being held together by a formerly liquid cement leaving a texture reminiscent of a liquid flow on the edge of the broken channel.

There are also signs of the almost ubiquitous spore-body like microspheres with holes erumpent on the upper surfaces and presenting like bumps on those surfaces.

Also seen are the exposed dark subsurfaces that were previously beneath the broken rocks and their hints of fineness, pliability and perhaps moisture as well.

All in all a nice image but of course the possible lessons from it will not be followed up.

The principal goal of the 2020 "Curiosity Clone" mission is said to be "a search for life" on Mars.

Sol 0327 Chemcam panorama of rock:

with location links back to a gigapan false color panorama of the area.

At first glance this rock looks like a boring finely banded sedimentary rock that the rock guys are looking for. But close inspection of the Chemcam view reveals a fine network of parallel linear features normal to the bands. Is NOTHING simple on Mars?

There are lots of these boring fine grained rocks in this area - but do they all have the weird hairy surface?

Sure hope a few MAHLI shots are done of these features.

Sol 0327 Chemcam panorama of peculiar rock:

with location link which links to a sol 0325 false color panorama of the area.

The LASER zaps missed the most peculiar areas of these peculiar rocks. Why THIS rock and not one of any other one of thousands?

To quote Roy Neary:

Well I got a couple of thousand goddamn questions, you know. I want to speak to someone in charge. I want to lodge a complaint. You have no right to make people crazy!
