Neat article

Not wishing to start a miles-per-watt race, here is one that I doubt anyone can top.
.
Voyager 1
.
........In my lab we had a brief ceremonial observance last week, of sorts, to mark its 40th year**. It is not one of our babies, but I can say that I have 'tuned in' its actual signal- though what seems eons ago- as a grad student.
.
Voyager 1 was launch on 5 September 1977, and has been operational on S and X Band telemetry since then. At its extreme distance, the original 115k data stream has been markedly reduced by the inverse square law, a phenomenon, while seen here terrestrially, is pronounced at this extreme distance.... +11 Billion Miles !

Fly on, little Buddy... God Speed to you !
