Do you really think that there is not any good reason to believe, and then say, that the Martian Sky, sometimes, may show, to a human eye, a light blueish (with some light orange nuances inside) color, instead of its "usual" thick dark brown/yellow or even dull green (like it happens, for instance, during a Sand Storm), or white (and this usually happens when it is covered by dense layers of Water-Ice Clouds) or even pink (like it usually occurs at Dawn and during the pre-Dawn hours as well as in the hours that follow the Sunset)?

Well, and as a matter of fact, we DO believe that there are cases, like the one that we proposed you in todays's APOD, when the Martian Sky can actually show some blueish color, especially in the areas of it which are near the Horizon and up to 25/30° above.

Why?

Because, in our opinion (as IPF), the Martian Atmosphere (as we already had the chance to say and write, in the past) is/should NOT be omogeneusly made of Carbon Dioxide and a few more trace Gases, like the so-called Common Knowledge (or either the Conventional Wisdom) taught us it is. 

We believe that, probably, there are regions (better would be to say "bubbles", and, probably, even big ones!) inside it which may contain several gases other than CO2. Gases whose density and composition should allow the verification of the so-called Raleigh Scattering, exactly like it happens here, on the Earthly Skies.

You do not believe that this is possible? Well, maybe you are right. But the final proof that the Martian Daytime Sky has, now, at all Latitudes and almost at all times, a dull "butterscotch" color (like NASA People have been telling us in the past 10/12 years), has not been given so far. And therefore, please, let us free to use our own heads and experiences as well as our best judgement and knowledge to make an informed opinion and, at the same time (and in conclusion), please let us think that - maybe once in a Blue Moon - the Great NASA could have made a mistake (perhaps, a big one...).

And let's not forget that, since the Future holds the final answer, the smartest thing to do now is to study, theorize, speculate and wait until one day (hopefully) we'll see...

 

This frame has been colorized in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were on the Surface of Mars, near the NASA - Mars Exploration Rover Opportunity, and then looked towards the Horizon and Sky), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
