Turns out we're getting jumbled data here on Earth, because the probe's attitude articulation and control system (AACS) has been sending back information through an onboard computer that had stopped working years ago. (engadget.com)
However, in mid-May, Voyager 1's onboard component responsible for maintaining its high-gain antenna pointed at Earth, known as the attitude articulation and control system, or AACS, began beaming home incomprehensible jumbles of data instead of the regular bulletins about the spacecraft's health and status.
