At 14:38:40 UTC the Mastcam Right has taken this photo of an evident water flow!
Thanks to the report of a reader, I was able to trace this photo of five years ago in which there were already evident flows of water!
It is unbelievable how a similar photo has been able to pass unnoticed despite representing clear evidence of the existence of water spills. For those who think that water on Mars should evaporate instantly, I am happy to point out that water, like any other liquid, evaporates as a function of vapor pressure determined by temperature, then, at low temperatures, water evaporates at the same rate as it would evaporate on Earth at the same thermal conditions. We all know very well that even on Earth if we pour water on the sand exposed to the Sun this evaporates more or less quickly depending on the environmental temperature. The same thing happens on Mars, the only variation is that if the pressure is lower than the triple point (6.11 hPa) this boils as well as evaporate. But the boiling itself does not accelerate the evaporation process, as much as a pot of boiling water does not evaporate instantly.
Be careful not to be fooled by the usual popularizers that want you to believe that water on Mars can not exist in liquid state. Meanwhile, because in the landing points of the various landers, including Curiosity, the pressure is always greater than the triple point indicated above. However in front of the evidence is useless to climb on the mirrors; RSL are a well documented reality, as well as this photo and the photo shown in the previous post.
To show colors more similar to what the human eye would see, I subjected the image to noise reduction due to Jpeg compression, white balance, and a slight increase in microcontrast and color saturation.
