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.Original image: https://mars.nasa.gov/msl-raw-images/msss/02737/mcam/2737MR0143480151200706C00_DXXX.jpg This post has been automatically translated.

At 09:10:39 UTC the Mastcam Right took a picture really rich of interesting details…Let’s start with the rocks, full of sharp edges and corners, in a context where otherwise prevails a strong erosion and therefore where the other rocks are smooth and blunt.On the right side of the image, we can observe the imprint left by one of the rover’s wheels by the sharp and defined contours, as if the ground was plastic and compact as wet clay.Also note how the ground moved by the wheel of Curiosity is the same color of what seems to come out from under the largest rock visible at the top.Other color tones are also visible in the soil, such as blue in the upper left or green at the bottom, almost as if to complete a pretty picture.What do you think, does liquid water have something to do with it here?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.

At 09:18:37 UTC the Mastcam Left photographed a field of sand dunes, with a track left by a rover wheel.The aforementioned track is visible in the lower part of the photo and in some places it has removed the superficial sand layer thus exposing the layer below.Thanks to this expedient, we can observe how the turquoise tint that characterizes these sand dunes is present only in a thin surface layer under which the coloration is decidedly more brownish.Considering that the windblown dust is decidedly reddish, where does this layer between green and turquoise come from?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”.

At 03:48:48 UTC the Mastcam Right shot again the excavation in the rock called “Edinburgh”, after eight days since the last shot (see https://www.facebook.com/PianetaMarte.MdM/photos/a.1625578140858706/2831070830309425/). In fact in the meantime have been made several shots at night with LED lighting, shots that at the moment are difficult for me to balance with the same accuracy as those taken in sunlight.From the comparison with the last shot, you can see some noticeable settlements in the excavated material, as well as the intensification of greenish spots all around.It’s really incredible to be able to observe color changes in such a short time!Physical-chemical or biological interactions?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.

At 01:20:10 UTC Mastcam Left captured a beautiful blue sky and a variously colored landscape.Red-brick, old pink, brown, green and turquoise with an area in the distance that looks like the result of a landslide or perhaps a mudslide….Not just red on the Red Planet!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”.

At 01:18:28 UTC the Mastcam Right captured in detail what appears to be the result of a landslide or perhaps a mudslide.From the appearance would also seem relatively recent, given the obvious difference in color tone compared to the surrounding terrain, perhaps more appreciable in the panoramic photo of the previous post (see https://www.facebook.com/PianetaMarte.MdM/posts/2841888069227701). Who knows if Curiosity can give us more information on this interesting detail.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”.

Between 01:45:42 UTCand 01:46:02 the Mastcam Left took three photos each taken through a narrow band filter in one of three individual RGB colors, from the combination of which I obtained this beautiful photo of the Martian soil.Notice the “tigerish” look of the sand, but especially how the color rendition is extremely similar to photos that normally undergo white balancing. This is because normal “raw” images use the normal Bayer mask (color coded or not) without an infrared cut filter, where therefore all colors tend to pink (see http://www.astrosurf.com/buil/d70/ircut.htm). The image was obtained by combining three black and white photos but each taken through a narrow band filter in each of the three individual RGB colors.In addition, the photo has undergone a reduction in noise due to Jpeg compression and a slight increase in microcontrast and color saturation.Given the use of narrowband filters, no white balance was necessary in order to make the colors more similar to what the human eye would see.

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.

At 21:56:46 UTC Mastcam Right captured a beautiful plain between green and turquoise, adorned with a brown hill and blue sky.The sky appears just a bit milky, perhaps haze on the horizon, but the coloration between the foreground and the hillside is truly spectacular. I fervently hope that the area will be imaged again in the next few days to see if this coloration is a stable feature of the ground or if it evolves as the days go by; I’d bet on the latter.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”.
