Highly recommended viewing: spectacular new views of Saturn and its rings taken by the Cassini spacecraft and compiled by "The Big Picture" at Boston.com.
I am constantly astonished by what we take for granted. When I was born, the only views we had of other planets came from Earthbound telescopes. I was 5 when Mariner IV flew by Mars and shot the first successful photos of another world (not coincidentally, I write about Mariner IV in WHTTWOT). I remember when Pioneer and Voyager were launched toward Jupiter and beyond, remember Viking landing on Mars, Venera landing on Venus. Man I loved that stuff. Each picture as precious as gold (probably literally, on a cost-per-image basis), I absorbed them all. Even now, when I see photos returned from space, I get a tingle in my spine that means "no one else in the history of forever has seen that before now."
Today we've got near-permanent satellites orbiting Mars and Saturn, rovers crawling over Mars, a European probe (Rosetta) due to land on a comet in 2014. It's all too much for anyone to absorb now. But once in a while, something like The Big Picture comes along to smack me in the face and remind me what an amazing time we live in.
