With any luck it will system reset in October and re-align itself to
Earth automatically. It is a heck of a long way away now!

It is a bit sloppy to send a bad pointing command though - such things
are usually carefully simulated and sanity checked before transmission.
Luckily there is a fail safe recovery mode but they don't like to rely
on that.

The Voyagers have way exceeded their design lifetime - the only reason
that we can still communicate with them now is that Earth based
receivers have become a lot more sensitive since the late 1970's. Can't
do anything about the transmit power at the far end - it is what it is,
but they have seriously upgraded the preamps on the big dishes.
