Voyager 1 stops communicating with Earth
(edition.cnn.com)
This is a most excellent place for technology news and articles.
I don't know if I would consider Voyager to be 'dead' if it stops transmitting.
If I put a message in a bottle, with a blinky light on it, then throw it into the ocean, the message is still there even if the blinky light goes out.
