Voyager I is 100 Astronomical Units from here. That’s 100 times the distance from the Earth to the Sun (93 million miles = 1 AU). Voyager I is 14 light hours from home and it took 29 years to get that far.
The really mind-boggling part is that no one can fix it if things go wrong and, so far, nothing has gone wrong. Can you imaging leaving your computer running for 29 years? It would never make it (and yes, even a Mac wouldn’t survive that long). The hard drive alone would deteriorate and die relatively quickly. But this thing built with 1970’s technology is still truckin’ along diving ever deeper into the empty depths of our night sky.
It makes me feel a bit smaller.
