*Somehow, they couldn't afford a color camera aboard the spacecraft. Yes, I know there must be some "rational" excuse for this grotesque aesthetic failure. Someday they'll explain to a wondering mankind why they sent an Xbillion-dollar probe the size of a bus to a distant planet, and yet Saturn is both pixelated and gray.
*I'm guessing –let me help you spaceprobe dudes out here – maybe, the planet Saturn is too mired in Eurodebt to afford any coloration. Maybe the Sun is too far away to solar-power the Photoshop filters. Cassini couldn't afford a pro FlickR account. There was a suburban real-estate crisis on the moons.
PS Get some genuine Cassini-style Italian music, instead of that dreary, hokum 8bit soundtrack! Look at these guys! They're no-budget Turinese hippies and they're mopping the floor with you!
