Thinking about Ray Bradbury ... someone sent a link to this poem read at JPL the night before Marineer 9 went into Martin orbit. I remember a talk by Carl Sagan shortly before he died where he read this poem - noting it was very important to him.
I'm not a great fan of manned spaceflight - the notion of spending the money on science and pure exploration appeals to me much more, but I realize there are forces other than exploration that drive people and also forces that limit the scale of science and real exploration. But that doesn't keep one from dreaming.
A few months ago Phil Plait, an astronomer I know a bit, was asked to give a talk at a high school science fair awards ceremony. Just before the talk he caught the local TV news which was giving "equal time" to pseudosciene. He reacted by pulling out his notepad and rewritting his talk on the sport. He gave it and it made its way around through email and blogs. A few days ago an artist took the words and illustrated it.
