I love it when we do shit like this. Makes me feel all 'humans are awesome'. Plus, astronomy etc, everyone loves this stuff.
Jumblr, on the Voyagers front, they are still transmitting, but there's no guarantee they'll last forever (even when inactive). Space isn't a total vacuum, so micro meteorites/any old shit they might run into in the Oort cloud region may well put paid to them a bit earlier than expected.
Also, this coincides with the item I currently covet the most in the world: the mars globe
