This was a uni assignment I did two years ago with a guy called Lincoln Berry. Google him if you want a wedding cinematographer. He did all the pretty sound design, miscellaneous spacey beeps and bits that sound nice. I did the words. And read some of them out loud (in a smug, nasally, want-to-punch-myself-in-the-face kind of voice). I also cannot say the word "exploration", which is pretty embarrassing, I think it has something to do with the shape of my mouth. Listen to it with headphones if possible.
It's fairly self-explanatory, about eight minutes long, but the elevator pitch is this: A radio story about the pale blue dot we call home and the magic of the Golden Record that floats through space, featuring Carl Sagan's actual voice.
