Hard to believe it's been 40 years since we first put people on the moon. It's harder - maybe even sadder - to believe that in all that time, we haven't gone beyond. It's the 21st century, and yet the future seems further away then ever some days.
(And yes, I realize that spending, presumably, billions and trillions on space exploration seems a bit frivolous given the current economic and social climate, but I'm still naive enough to believe that having a frontier to explore - and actually doing something about it - makes everyone more ambitious to tackle the rest of life's problems. And Cronkite would've loved it.)
