At 03:28:43 UTC the Mastcam Left has taken some outcrops of stratified rocks from which start some water flows!
The two most recent ones can be seen in the upper left corner, but many others less marked (less recent?) are visible a bit ‘everywhere; obviously could not miss the greenish spots!
As you can easily verify in the official website of REMS (Rover Environmental Monitoring Station), the meteorological station on board the Curiosity rover
(see https://cab.inta-csic.es/rems/marsweather.html), since last January 24 (Sol 2654) the ground temperature (Ground temperature) has begun to rise above the thawing point of the ice (0 ° C) arriving in February to reach and exceed +10 ° C.
If we add that the atmospheric pressure inside the Gale crater is always higher than the minimum value necessary for the formation of liquid water (also called “triple point”, its value is 6.11 hPa or 611 Pa), it should be more than logical to attribute these formations to the presence of liquid water!
Yet no one talks about it and no one else highlights these photos that for a few weeks appear among the raw images on the official NASA website; there will be a limit to this “media shame”???
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.
