NASA is not positive if an issue with Voyager 1’s onboard pc will be mounted : NPR

ARI SHAPIRO, HOST:

The Voyager 1 spacecraft rocketed off our planet in 1977. It is now about 15 billion miles away. That is farther out than some other object made by people. And the spacecraft nonetheless talks to Earth. However as NPR’s Nell Greenfieldboyce stories, recently its messages do not make any sense.

NELL GREENFIELDBOYCE, BYLINE: Voyager 1’s drawback began a number of months in the past, again in mid-November. Suzanne Dodd is the Voyager undertaking supervisor.

SUZANNE DODD: It principally stopped speaking to us in a coherent method.

GREENFIELDBOYCE: The spacecraft is simply sending again alternating ones and zeros. Her crew has tried the same old tips to attempt to reset issues with no luck. It seems like there’s an issue with the onboard pc that takes info and packages it as much as ship residence. Dodd says this know-how is primitive in comparison with, say, a automotive key fob.

DODD: The button you press to open the door of your automotive – that has extra compute energy than the Voyager spacecrafts do. You understand, it is exceptional that they hold flying and so they and that they’ve flown for 46-plus years.

GREENFIELDBOYCE: Voyager 1 and its twin, Voyager 2, have outlived lots of those that designed and constructed them. To attempt to repair Voyager 1’s present woes, the dozen or so individuals on Dodd’s crew have needed to pore over yellowed paperwork and outdated mimeographs.

DODD: They’re doing loads of work to try to get into the heads of the unique builders and work out why they designed one thing the way in which they did and what we may presumably strive which may give us some solutions to what is going on incorrect with the spacecraft.

GREENFIELDBOYCE: She says they’ve an inventory of issues to strive. Since their go-to approaches have not labored, they’re going to need to take measures which might be extra daring and dangerous. This might take weeks, months of sending instructions to the spacecraft. Voyager 1 is so distant, it takes nearly an entire day for a sign to journey on the market, then an entire day for its response to return.

DODD: So we’ll hold attempting, and it will not be fast.

GREENFIELDBOYCE: Within the meantime, Voyager 1’s discombobulation is a bummer for researchers like Stella Ocker. She’s with Caltech and the Carnegie Observatories.

STELLA OCKER: We have not been getting science information since this anomaly began, and what which means is that we do not know what the surroundings that the spacecraft is touring by seems like.

GREENFIELDBOYCE: That surroundings is not simply empty darkness. There’s gases, mud, cosmic rays. Solely the dual Voyager probes are far-off sufficient to pattern this cosmic stew, and solely Voyager 1 continues to be capable of take the actual measurements she wants.

OCKER: So the science that I am actually focused on doing is definitely solely attainable with Voyager 1.

GREENFIELDBOYCE: Now, she wasn’t even born when the Voyagers launched. For different scientists who’ve been with the Voyager program from the beginning, Voyager 1 is like an outdated, pricey pal who instantly has been hit with a horrible sickness.

TOM KRIMIGIS: Nicely, frankly, I am very fearful.

GREENFIELDBOYCE: Tom Krimigis is with the Johns Hopkins College’s Utilized Physics Lab.

KRIMIGIS: My motto for a very long time was 50 years or bust (laughter), however we’re form of approaching that.

GREENFIELDBOYCE: So even when this present disaster will get solved in a few years, the ebbing energy provide will pressure managers to start out turning off science devices one after the other. The final instrument may hold going till 2030. After that, Krimigis says each of those legendary area probes will principally develop into area junk.

KRIMIGIS: Pains me to say that.

GREENFIELDBOYCE: And whereas the spacecraft will hold shifting outward, every carrying a set of golden data which have recorded greetings in lots of languages, Krimigis doubts that any alien will ever stumble throughout Voyager and have a pay attention. Nell Greenfieldboyce, NPR Information.
