Voyager 1 is about to reach a distance no spacecraft has reached before: On November 18, NASA’s veteran explorer will become the first human-made object one light-day from Earth, roughly 16.1 billion miles away. At that distance, a radio message takes 24 hours to reach it and another 24 hours for a reply to return. The milestone follows an October communications scare, when NASA lost the probe’s signal for 48 hours before contact returned on its own, without troubleshooting commands from Earth.
Just remember, it's a long way to the top (if you want to rock'n'roll).
And for some, that's an eternity.

Yeah it's a mighty long way down rock 'n' roll
From the Liverpool docks to the Hollywood bowl
'n you climb up the mountains 'n you fall down the holes
All the way from Memphis.
