NASA fixed the glitch that caused Voyager 1 to send back jumbled data:
Back in May, NASA reported that the Voyager 1 space probe was sending back jumbled or inaccurate telemetry data. The probe itself seemed to be in good shape, with a signal that's still strong enough to beam back information, and nothing was triggering its fault protection systems that would put it in "safe mode." According to NASA, the Voyager team has not only figured the problem out since then - it has also solved the issue.
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. The computer was corrupting the data before it even went out. Voyager project manager Suzanne Dodd said that when her team suspected that this was the issue, they implemented a low-risk fix: They commanded the AACS to send its data through the probe's working computer again.
