Description

I reprocessed 4 RGB & IR captures from August 4th 2018. The data were good, but my previous image processing was not. For me this is a fascinating image.

It is the clearest image I have which shows the transition from a yellow coloured dusty Mars to the more familiar brick red terrain. It also makes it clear that when covered in dust, Mars was distinctly yellow with a hint of pink in colour and for those images where there is a strong red hue, including my own, this is I believe confirmation bias. We make Mars red because it is supposed to be red.

It shows the Mare Cimmerium and Sinus Gomer to the south (up in this image) emerging from the dust clouds, yet there are very distinct clouds of dust all over these albedo areas. Elysium Mons sits well clear of an encircling dust cloud and has a reddish tinge. Its cone is lit on one side by the sun and cast a shadow the other way. A large dust cloud is to its east (left) and you can make out the billowing structure. To the south there seems to be a hole in the dust cloud revealing the darker and redder terrain underneath. Equally there is a higher level cloud of dust over Mare Sirenum at upper right in the image. I managed to avoid blowing out the South Polar Cap (SPC) and there it is quite dark with encircling white cloud.
