Yes, the panels are the 'wrong' colour which would mean that it is colour adjusted.
There seems to a be a lot which is shown to us as blue on Mars - either through false colour
or supposed real colour as in blue blueberries or blue lichen in other pictures.

Do we know what false colour is and how it differs from 'real' colour and from other altered photographs?
Isn't this just another creative way to see the photos from Mars? If there was no Rover in the picture
we would have never known and just taken this as the 'real' thing.

I assume it is all just a different weighting when putting back together the images taken with different lenses
which capture the different wavelengths of light on Mars. This often comes down to creative imaging as everyone
see differently depending on how their eyes work. My green is different from your green.

The point is that some of the scientists at JPL
have a very strange view of what we would see if we were there, and this view is very different from that
posted on other sites where colour composites are created from the same data. The sky is just one example,
and the redness of the landscape we have been fed since the start of Mars missions is another example.

Are you sure that left image isn't false color?  The panels look pinkish.

Strangely, that just looks like blue rock to me and not like lichen at all. It does not have that 'feel' to it and could be caused by outside weathering of a mineral on the surface of the rock perhaps.

We know that many of the blueberries are this kind of colour and we know that after the RAT has drilled through the surface layer, there is often blue rock underneath the outside brown layer.

Compare this with the second picture in this thread, for example, and I think there is a fair bit of difference.

Yes, this is good info. I have not noticed any further images of fungus which is strange but perhaps it is because I have not been looking for it lately. We should all keep our eyes open for it and if we find any more, post them on this thread. Keep it all together for long-term research.

Interesting read, but if that is a geological process, then we would need an explanation as to why it never occurs on Earth.  There is a microscopic image, too.

1)The point is.. that even if it is not this colour, it still has the feeling of lichen to me.
It does look like lichen. http://en.wikipedia.org/wiki/Lichen
2)Maybe I will find some photographs of tree and rock lichen to be used as a comparison and we can see if it looks similar.
My Wikipedia link should have enough images of lichen to make a comparison.
3)Fungus and lichen on Mars
Lichen is technically classified under fungi, however they are composite organisms. They are not composed completely of just a fungus- they also incorporate a microscopic photosynthetic component. Source: en.wikipedia.org

Of course, I could be wrong as I am not an expert in any of these areas, but I have seen lichen growing on trees and rocks before and looked at it fairly closely.

The part that looks as if it is thin and peeling reminds me of the lichen and the colour adds to that. Maybe I will find some photographs of tree and rock lichen to be used as a comparison and we can see if it looks similar.

They say....
Initial analysis was inconclusive about whether the coating on the rock is material that melted during the impact event that dug the crater.

I suppose they can hardly say that it is lichen. Imagine what a fuss that would cause!


Hi qumantoo, it could be lichen ...or else, who knows?

You interpret false color incorrectly. Here is a definition.

Trying to keep these all on the same thread, I think maybe this is more of the same. Take a look and see what you think.

You know how bracken or fern starts out all tightly curled up and then as it grows it uncurls. Maybe this is that perhaps?

gmantoo, the image number is fine. We all seem to have our own favourite image source sites that we use so we can access the image in our own favourites with the number. 

Having a link makes it easier and quicker for someone to follow your work, its probably good etiquette to post it so viewers can see what you were looking at if you want them to give opinions.

In fact typing this I realise I should probably do that....but like you I download a lot at a time and then work on them later.....I'm just being lazy disbelief You can google the image number, find a site to post a link to it in a few moments.....(I am talking to myself here gmantoo and its 3am in the morning so I should be asleep and not talking to anyonesmile )

Thanks Iceman. The problem is that I go through a site and download interesting photos and then when I find something later, I only have the photo number on my computer, not the whole link.

These are all from the same site as I got the red circle one from, but I dont know the sol number from the file name (well I can probably work it out, but I dont).

Without the sol number I cannot get back to the photograph on that site. It is just laziness I know. I wonder if I should write a program to convert a mars photo number into english translation sometime? I have all the details somewhere on my computer.

Obviously lichen and fungus is thriving all over the place confuse

This looks as if it is growing on the rock as if it is lichen

This looks like a fungal fruiting body possibly containing fungal spores.
