At 15:44:02 UTC the Mastcam Right has captured this very particular rock, below which a small strip of darker material seems to come out, oriented to the right; also two small stones, much closer to the right edge, present the same phenomenon that perhaps is simply due to a small relief of sand.
The rock in the center has a turquoise coloration, totally out of context compared to the surrounding stones; could it be a meteorite?
Even the morphology is quite unique, extremely smooth and blunt but with edges that seem very sharp.
Hopefully closer images will come along….
The original image is a black and white encoding of the Bayer mask that has been converted to color through a process called “debayering” or “demosaicing”. In addition, the photo has undergone noise reduction due to Jpeg compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.
