Beautiful view of Late Afternoon Shadows at Endeavour Crater on Mars

NASA's Mars Rover Opportunity catches its own late-afternoon shadow in this dramatically lit view eastward across Endeavour Crater on Mars.

The rover used the panoramic camera (Pancam) between about 4:30 and 5:00 p.m. local Mars time to record images taken through different filters and combined into this mosaic view.

Most of the component images were recorded during the 2,888th Martian day, or sol, of Opportunity's work on Mars (March 9, 2012). At that time, Opportunity was spending low-solar-energy weeks of the Martian winter at the Greeley Haven outcrop on the Cape York segment of Endeavour's western rim. In order to give the mosaic a rectangular aspect, some small parts of the edges of the mosaic and sky were filled in with parts of an image acquired earlier as part of a 360-degree panorama from the same location.

It's presented in false color "to make some differences between materials easier to see" but I was wondering what could be the real colors for this view?

We can only imagine the real colors of Mars.

The BLUE became RED on Mars.
And this is really a mistery...

Why NASA don't show the real colors?

True Colors of Mars

To Mods: why Zorgon is banned?

Please U2U me. Thx.

The answer, (which Zorgon never really seemed to understand despite being told multiple times) lies in the question of which filters were used to take the photos.
The rovers have several optical filters which are outside the range of human vision.

I quote from the article attached to the photo presented above...

The mosaic combines about a dozen images taken through Pancam filters centered on wavelengths of 753 nanometers (near infrared), 535 nanometers (green) and 432 nanometers (violet).


Because one of the filters was in the InfraRed, outside the range of human vision, it MUST therefore be presented to you in some kind of artificial false color.

This is also true of most other rover images, including the often cited conspiracy example of the "sundial", parts of which were "blue" becoming "red".

Stealing from another thread... www.abovetopsecret.com...

The filters used on the Pancams....

LEFT CAMERA..............RIGHT CAMERA

L1. EMPTY................R1. 430 (SP) *
L2. 750 (20)..............R2. 750 (20)
L3. 670 (20)..............R3. 800 (20)
L4. 600 (20)..............R4. 860 (25)
L5. 530 (20)..............R5. 900 (25)
L6. 480 (25)..............R6. 930 (30)
L7. 430 (SP)*............R7. 980 (LP)*
L8. 440 Solar ND......R8. 880 Solar ND

The L4, L5 and L6 filters correspond to Red, Green and Blue as we humans see it.
EVERY OTHER FILTER is outside the range of human vision.

Thats why the overwhelming vast majority of photos look "wrong". because they're basically invisible if NASA was to display them to you truly correctly.
Displaying an invisible photo is rather pointless, so they mock up something which looks roughly right so at least you have something to see at all, only to have conspiracy theorists go crazy.
