Blue Sky on Mars

[Ashim]

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.

How come NASA were talking about expecting blue skies at the start of the pathfinder mission?

From their own press release, not my idea and not a crummy youtube video or internet 'fantasy'.

"If dust diffuses to the landing site, the sky could turn out to be pink like that seen by Viking," says Philip James of the University of Toledo.
"Otherwise, Pathfinder will likely show blue sky with bright clouds."

Edit to add this screenshot of the control center. Take a look a the monitor displaying the landscape (left in picture).
Did they colour correct that too?
