Humanity’s most distant spacecraft is glitching out—once more—and engineers are having fairly a tough time fixing the issue. Voyager 1, what are we going to do with you?
The problem is with the 46-year-old Voyager 1’s flight information system (FDS), one among its three onboard computer systems. The FDS collects information from Voyager’s science devices and takes information on the spacecraft’s standing and common well being. The system isn’t correctly speaking with the telemetry modulation unit, which truly takes the information collected by the system and sends it to Earth.
That is simply the newest in a spate of communications points with the ageing Voyager 1, which launched in 1977, shortly after twin spacecraft Voyager 2. In Could 2022, the probe abruptly began sending nonsensical perspective articulation and management (AACS) information. Suzanne Dodd, undertaking supervisor for the Voyager missions, described the glitch as “par for the course at this stage.”
It turned out that the information was being transmitted by a defective laptop on the spacecraft, making it learn out as gibberish to Earth-based interpreters. Engineers resolved the issue by sending the telemetry by one of many spacecraft’s different computer systems. Within the three months between the issue arising and it being resolved, Voyager 1 traveled 100,000,000 miles.
In December 2023, Voyager 1 resumed sending gibberish; the telemetry modulation unit started emitting binary code that appeared to counsel it was caught. The mission group believes the difficulty really lies with the FDS, the place the information is definitely coming from. The Voyager group tried to repair the issue by rebooting the FDS, however that failed. The gibberish persists.
“It could be the largest miracle if we get it again. We actually haven’t given up,” Dodd advised Ars Technica. “There are different issues we are able to strive. However that is, by far, essentially the most severe since I’ve been undertaking supervisor.”
Voyager 1 is 15.14 billion miles away and continues to zip alongside at simply over 38,000 mph. It’s been two months, and the difficulty stays unresolved.
“We will discuss to the spacecraft, and it may well hear us, but it surely’s a sluggish course of given the spacecraft’s unbelievable distance from Earth,” NASA’s Jet Propulsion Laboratory said on Twitter. Each message despatched to Voyager takes 22.5 hours to get to the probe, and vice versa.
In any case, the Voyager missions are almost 50 years previous. They served their authentic goal a long time in the past, so daily we get information from them is a bonus. When the 2 Voyager spacecraft lastly sputter out or are given up on so far as information assortment goes, they’ll nonetheless be coasting—flying—into star-spangled infinity, as intrepid a retirement undertaking as any of us may ever dream of.
