Pretty interesting stuff. The Sun looks a lot smaller from there. Heh.

Hey, the sunset is blue-looking instead of red-looking. Interesting, I wonder why that is?

Probally something to do with the atmosphere. Or it's just the cameras are messed. I didn't know there was a colour version of that pic. I only saw a black and white one. Thats nice.

Wow, really neat picture...
As for your pondering, Crispy, my guess is that the quality of the picture might be to blame... However, there might be some scientific reasoning behind it... Likely something to do with the different (thinner, basically) atmosphere on Mars... The colors in our sky are caused by particles in the atmosphere scattering the different light wavelengths... Shorter wavelengths are the easiest to scatter... During most of the day our sky is blue because the violet wavelengths are completely scattered, and the blue wavelengths are only partially scattered, and hit our eyes (the other colors aren't scattered)... At sunrise/sunset, the sunlight is coming at us on an angle through much more atmosphere, and more wavelengths of light are scattered off... This leaves the oranges and reds to hit us... On Mars, due to the thinner atmosphere, this scattering effect is lessened... Daytime light would likely be either completely white (not enough scattering to throw off any of the spectrum), or perhaps a slight violet tint (some violet wavelengths are scattered)... Sunset light would have a greater scattering, but not enough to drop it off into the oranges and reds... It probably only makes it down to the blue seen in that picture... | |
