At 07:19:47 UTC Mastcam Right imaged this layered rock, adorned with singular outgrowths and with a particularly rough surface.
Many of these outgrowths have a curious “mushroom” appearance, that is, they end in a hemispherical top that is sometimes larger than the connection to the main rock.
But what is even more curious is that this “mushroom” structure is also found in the myriad of micro-excrescences that make the surface of the rock so rough.
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.
