At 06:27:47 UTC the Mastcam Right took another picture of the excavation called “Mary Anning” (see
A comparison with the previous image, taken only one day earlier, already shows some interesting differences. The surrounding rocks appear a more saturated red and some of the excavated material appears to have been blown by the wind towards the lower right corner of the image.
Curiously, some of the sand present between the rocks has moved in the totally opposite direction. This apparent contradiction could find an explanation in the vibrations induced by the internal activities of the rover, vibrations that could cause settling of the sand, moving it also in the opposite direction to the prevailing direction of the wind.
I want to emphasize that both this and the previous image have been taken with the same camera, in very similar lighting conditions and have undergone the exact same processing with the same parameters!
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 of 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.
