The above video is making the rounds of the Internet. It was produced by a fan of NASA who thinks that agency could use some help with their communications (and I tend to agree). It features Carl Sagan reading from his book "Pale Blue Dot " (which is a fantastic book).
This video is a little unfair to NASA if only because Carl Sagan was probably the best science educator there has ever been. Just listen to the man, and his words, in this video and tell you don't want to give 95% of the Federal budget to NASA. And the idea that it isn't us who will be colonizing the solar system, but a species very much like us.. that's pretty powerful stuff.
If fan made NASA propaganda isn't your thing, but you still want to hear Carl Sagan's words, check out this short film that uses the same voiceover (and music), set to some beautiful time-lapse photography:
