Happy Birthday, Voyager I

Guess who else turned 30 this year? Voyager I, and it's still out there sending us pictures. Imagine this, it's 9.5 billion miles away and takes 13 hours to send its signal (at light speed) to earth. That puppy wandered far! Keep up the good work, little space Voyager! (Get this, they even included a record of "earth sounds" for extraterrestrials to listen to to get to know our planet. Wasn't that thoughtful?
