You do have to remind yourself that this is a musical collage of space activity so many miles from here, produced by a videographer. Making it into into an art form reenforces the real hard work that so many NASA enginers and scientists poured into so many space probe technologies: http://www.jpl.nasa.gov/missions/
I wonder if our instant-gratification culture has the patience for such long-range, long-period projects: http://www.eetimes.com/electronics-blogs/other/4205118/Do-we-still-have-the-patience-and-stamina-for-deep-space-missions-
An excellent book on the dual Voyager probes is: "Voyager: seeking newer worlds in the third great age of discovery", by Stephen J. Pyne, a lengthy but fascinating look at the 30+ year dual missions (launched in 1977, and recently officially concluded) to the edge of our solar system, and beyond.
Equally astounding is the fact that one of the Voyager spacecraft is about to leave the solar system and enter interstellar space. Voyager 1 (two were launched to ensure the mission would succeed) will be the first man-made object ever to leave the solar system. The Voyager 1 spacecraft is expected to continue sending signals back to Earth as long as its plutonium power source holds out, perhaps until 2025. What a machine!
