Why wouldn't it be blue?
The surface being red has nothing to do with the sky.

our sky is blue bc the makeup of the atmosphere diffracts the sunlight a certain way

with a different atmosphere and different particulate in the air, it could diffract the sunlight differently on mars

but yes, you are right that the surface doesnt have an impact. i dont know any details, but its not true that all skys = blue.

That was my thinking every time I saw an orange sky in the pictures.

"Blue skies on Mars" !! :Q

Blue skies smilin' at me
Nothing but blue skies do I see

Come on, do you REALLY think that nasa sends out billion dollar rovers, and doesnt know how to calibrate their cameras? I'm sure the sky on mars shown in nasa pics (pale orange) is most definitely the proper color.

They don't have colour cameras on them. All real high-end ccds take pictures in black and white only. You get colour by taking 3 separate images with 3 different filters R V and B usually. I've seen a few colour composite images of mars from spirit and opportunity, but they're all of the ground only... nothing of the sky.

just like they used the metric system to calibrate a probes decent but it was acutally in standard measurement?

Actually Mars is really cool.



O snap

did you just 'snap' yourself? is that even legal?

If you look at a few of a pictures from the rovers you'll see a calibration device, link.

hehe that's pretty cool

 

[shimsham]

there was an article in discover magazine 2mos ago dealing with this. mars actually looks pretty much like earth as far as color goes.

link, but you have to register.

Indeed, and, with a color calibration device, the resulting picture of the sky looks like this.

The Pathfinder probe ALSO had color calibration tools on it. And for a really crazy look at the pictures it took, check it out.

Exactly. Whether or not some idiot messed up a calculation doesnt take away from the fact that they have two rovers on mars, for quite a bit longer than they were supposed to be. Overall, they know what they are doing, and I've seen the calibration device that dderidex linked to.

Anyone can make a blunder, but to miscalibrate the color on every single image that every probe has ever taken is certainly out of the question. The sky is orange.

I too have the director's cut of Total Recall.

Remember this is the same NASA that forgot how to convert Metric to Imperial, and vice versa...


**EDIT** Dammit! Citrix beat me...

 

[Scarpozzi]

Ahh....we have blue skies here too. Big deal....no need to go to mars if it isn't any different.

That was one man's error. This is also the same nasa that routinely sends probes and robots to the most remote, unimaginable places. Aside from a few bad apples, I'd say they know what they are doing, more than some schmoe on the internet.

 

[Bootprint]

Has Nasa taken sky only pictures from one of the Mars rovers? Usually when I take pictures of the ground the sky gets blown out or at least is overly bright.

 

[BD2003]

From the linked site:

"I chose to try these values as they correspond to the white calibration values, and the sky is typically a bright object. However, there are no true white images in the field, so this could be wrong."

There are true white images on the color calibration tool linked above. They have a point of reference, and there is absolutely no reason to doubt it.

Dammit! Turn your sarcasm meter on...

it's like that joke about the Scottish guy who builds wonderful things... "... but you shag one sheep"
