Blue Sky on Mars

[zenmaster]

The picture from curiosity shows Mt. Sharp with a nice baby blue sky.
Either someone slipped up in the photoshop department or they are allowing these images to filter through.

Whenever you see the blue sky on Mars, it's because they purposely changed the white balance to be earth-like. This allows geologists to more readily recognize details in the rocks.

......or to slowly introduce the public to the truth.

That there is not enough molecular absorption on Mars to render the surface "red"? Have fun with your fantasies.
