that rock behind has a massive specular highlight, the trinkets is small and concentrated on the curve

not comparable as materials go unfortunately

they show different reactions to light

I don't think it's a specular highlight, and the "trinkets" is less bright than the rock behind, as it would be if it was made of the same material, as it shows a smaller area facing the camera.

How can you know that just by colour of the pixels?

a reply to: ArMaP

because the rock behind it has a soft specular highlight

the object underneath has a sharp specular highlight

shininess of the two are different as indicated by the specular highlights

if the rock behind was like the shiny thing in front then it would have many sharp points of specularity , not blended altogether as it looks now . the curve of the trinket indicates a high reflective index ., like brushed metal

are you referring to that unusual thing to its right Aleister ?. the brown thing looking like a a ridged crisp ?

a reply to: funbox

YES I scream as the cap lock lock up, the sea-shell like maybe segmented piece just on the right of the shiny pen. But once again we are all foiled by the percentage of zoom this has to endure to exhibit it's properties.

a reply to: Aleister


ahh its not so bad Aleister , it could be on the horizon surrounded by angry looking jpg artifacts

wielding spears even

don't forget there's a bit more to be got from zoom, when the camera is facing towards the ground

but indeed ill consign, once again this one to the potential maybe/maybenot box due to N.A.S.A ' S, 'more is merrier policy '

to think , if they put some rubber on the tyres , we wouldn't have all the pictures of scarred metal wheel , taken by the best camera, and maybe leave some bandwidth for some high res wheeless pictures

I don't see any specular highlights in any of those rocks.

We can only see differences in colour, we don't have any way of knowing reflectivity just by looking at the photos, unless we could see Curiosity reflected in it somewhere.

I think it's just white.

I think it's just a bright coloured rock.

ok , can you see highlight on the rocks all over the picture? can you see light gradiating to shadow on some of the surfaces?

ill stop using 3d modelling terminology

heres what wiki says about specularity

Specularity is the visual appearance of specular reflections. In computer graphics, it means the quantity used in three-dimensional (3D) rendering which represents the amount of specular reflectivity a surface has. It is a key component in determining the brightness of specular highlights, along with shininess to determine the size of the highlights.

its not just about reflections , as if you would see any at this resolution

I think it's just white.

fair play

I think it's just a bright coloured rock.

even with all that dust? .. how did it stay unaffected ? ..hmmm..!... maybe its surface is smooth and shiny , frictionless

dam , I hated that .. ill not do it again

I can, obviously.

That's probably the problem, as I was interpreting "specular" in the more common (as far as I know) sense of "mirror-like".

Why, is everything equally covered with dust?

a reply to: ArMaP

I doubt the feeble wind has that kind of marksmanship to get it distributed fairly.. im sure some rock species are discriminated against, maybe some of the more favoured by the blue it tribes, wind can be so fickle at times

Shiny. And since we mention the blueit people every so often, I'll put the Mars photo of a blueit up so people can either gasp in horror, smile while wanting to cuddle it, or carry their rock hammers to it to chip off some of that obvious rock structure (blueits paws turned out to be something else worth oogling, I mean googling).

Interesting parallel grooves or striations (slightly contrast-enhanced) ...

I haven't really noticed features like these on the other rocks before, perhaps they are glacial striations, concretions of strata ... or something entirely different altogether? Remnants of a geologically more active period?

It's a lake bed.
Lakes form sedimentary rocks. In layers.

a reply to: Phage

Yes, Phage ... the basics, always good to remember!

I guess it would be more precise then to call those features concretions of sedimentary layers (instead of strata). Yet, I haven't seen many of those chunks lying around as seen in that image, with such regular striations.

a reply to: Aleister

now I look back on the it , it looks to me like its got some shades on its head

another picture of shiny thing , still looks odd , starting to remind me of an old gramophone

And now that I look at it better I see that the brighter rocks appear to have been broken by Curiosity's wheels.

a reply to: ArMaP

which opens the door. no doubt, to the shiny piece being a fragment of the larger rock I suppose ?

at least we know where the dust went from the rocks surface

funbox

Is it me or does that rock in the centre of the photo looks like a bone?

a reply to: ArMaP

the one half covered in dust , slightly deformed thigh bone ? I see it
