HI Brian

I've been trying to determine which substrate it is without success so far. The image label info gives a rotational position (12942) and a focus position (49111) but I can't find where they fit on the substrate wheel so far.

I suspect that it is the substrate which has given rise to the organic appearance seen, perhaps one of the silicone substrates or the pho bucket substrate. I've also tried to see if there was a "before" image also without success so far.

For now, it looks as if the organic appearance is due to the substrate and not anything from Mars.
