At 09:07:16 UTC the Mastcam Right shot the same rock of the previous post, but the far side (see https://www.facebook.com/PianetaMarte.MdM/posts/2870331226383385).
Even here we can observe the imprint left by one of the wheels of the rover, with a nice darker spot with well-defined contours, as if water had leaked from the ground due to the pressure exerted by the weight of Curiosity.
Curiously then, in the upper left quadrant, you can see at least three “details” mushroom-shaped, very similar to the photo of Sol 2660 (see https://www.facebook.com/PianetaMarte.MdM/posts/2693091944107315) ; can you see them?
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 a reduction in noise 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.
