At 21:20:40 UTC the Mastcam Right resumed the excavation in the rock named “Edinburgh”, performed about ten days ago (see https://www.facebook.com/PianetaMarte.MdM/photos/a.1625578140858706/2804141806335661/).
Aside from some minor settlements in the excavated material, the formation of greenish spots all around is quite evident.
Don’t be surprised if the brightness of the surrounding rock is greater than in the previous photo, you will also notice that the shadows are different due to the different local time at which the two photos were taken; a different angle of illumination may affect the amount of light reflected but not its color.
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.
