Mars color

[schriss]

I agree. I also believe there are wonders on every planet/moon waiting to discover, I have also seen mars pictures where you could see effects of airbrushing (I work with graphics utilities myself, which helps to notice those things).


I'm very glad I don't live in US. It's not just what you believe in, it's possible to affect people on global scale, make them "don't care", don't ask questions, turn into sheeps in other words.

But there is so much more.

Anyway, I believe there are space missions we are not told about.

Getting back to Mars colors: there is an article "NASA Is Not Altering Mars Colors.", it talks about hardware used by NASA, filters and other stuff. But still, I can't imagine how would it not be possible to show real colors. They say its not possible.

One can not just take a infrared image and say, 'red or infrared, who cares ?' and use the IR image as red plane of a RGB image. You will always end up with a pseudo color image. If you then 'color correct' the pseudo color image just to match the color of a certain part, you will end up with something that is no step closer to the truth than the false origin.

They had a green plane in the cam, and yet the image is not green. So believe it or not, the mars is not green. A green planet does not make a red spot on the night sky.

No matter what, they COULD take some ordinary pics with simple digital camera we use everyday, with no stupid filters or infrared, couldn't they?

And yes, green planet does not make red spot, just like earth, which makes blue spot, is not all blue. Yet on NASA pics everything is red, sky, ground, even rocks so it looks more "hellish", toxic, no-life-there, not-friendly-environment, etc.

Anyway, ESA at least shows true color images in addition to false color and 3D, so it's not that hard:

an example of high res true color:

it is NOT insanely red as nasa pics. It looks like the desert, like we would expect it to look like.

they even offer 39MB High Res TIFF, not bad at all!

And here is the FAQ on colors:

Are the colour photographs processed?

Yes, the images have been processed but that is quite normal. We are not taking colour photographs, we have to combine the different colour channels which requires processing time. Each of the four colour channels operate with a filter of different wavelength (red, green, blue and infrared) and produce data sets which have to be combined and calculated on to a digital elevation model.

The colour channels are absolutely real, but they do not reflect the true colour as we would see it with our eyes. These views can be obtained by processing the data, which does not mean ?faking? the colours, but fitting them to standard spectral curves which we know. We adjust the obtained colour image data to a standard spectral curve derived from Earth-based observations in terms of wavelength and intensity.

If we have dust, haze or other atmospheric conditions, various wavelengths get partially filtered. Obviously, images get more blurry and some colours become more dominant. Sun-exposed slopes reflect or absorb light in a different way to dark slopes or dark material (such as dark spots of possible sediments seen in some images).

The main limitation, of course, is that from orbit we do not have any colour adjustment possibilities as for example, the NASA rovers. They have colour references mounted on their rovers and even they have problems matching their colours.

Speaking of airbrush, I hope this is new and fun for you, Clementine, moon, Government foolery. Hartiberlin, I know it's a big pic but let a few people download it before you delete it. Smaller it looses too much resolution, this is original size. I think the Indian government might be honorable enough to show us the truth, I hope they go there.

I have followed
http://www.cmf.nrl.navy.mil/clementine/clib/
then entered Latitude: -34, Longtitude: 207
and got same result as posted above, just not magnified but blurry blocks are clearly visible.
