I was once sitting with my sire while google how far away various things in thesolar systemare from Earth . He was looking for exact numbers , and very apparently grew more place with each new digit I cry out out . I was thrilled . The moon ? On modal , 238,855 miles ( 384,400 kilometer ) out . TheJames Webb Space Telescope ? Bump that up to about a million miles ( 1,609,344 km ) off . The sunlight ? 93 million miles ( 149,668,992 km ) off . Neptune ? 2.8billionmiles ( 4.5 billion kilometre ) away . " Well , expect until you hear about Voyager 1 , " I eventually said , put on he was aware of what was come . He was not .
" NASA’sVoyager 1interstellar ballistic capsule in reality is n’t even in the solar system anymore , " I announced . " Nope , it ’s more than 15 billion air mile ( 24 billion km)away from us — and it ’s get even farther as we speak . " I ca n’t quite remember his response , but I do indeed call up an reflexion of sheer disbelief . There were contiguous research about how that ’s even physically potential . There were bewildered laughs , different way of saying " wow , " and mostly , there was a contagious sense of awe . And just like that , a unexampled Voyager 1 sports fan was born .

It is easy to see why Voyager 1 is among the most dear robotic space explorers we have — and it is thus easy to understand why so many masses palpate a pang to their heart several months ago , when Voyager 1 stopped speak to us .

For cause unknown at the time , this ballistic capsule began sending back gibber in place of the neatly engineer and information - rich 0 ’s and 1 ’s it had been provide since itslaunch in 1977 . It was this classical computer language which allowed Voyager 1 to converse with its Almighty while take in the title of " uttermost human made object . " It ’s how the spacecraft relay vital insight that head to the find of new Jovian moons and , thanks to this sort of binary podcast , scientists fantastically identified a new halo of Saturn and created the solar organization ’s first and only " category portrait . " This codification , in nitty-gritty , is all important to Voyager 1 ’s very being .

Plus , to make matter risky , the issue behind the glitch twist out to be tie in with the craft ’s Flight Data System , which is literally the system that transmits information about Voyager 1 ’s health so scientists can correct any issue that arise . Issues like this one . what is more , because of the ballistic capsule ’s huge distance from its operators on Earth , it takes about 22.5 hours for a transmission system to touch the ballistic capsule , and then 22.5 hour to have a transmission back . Alas , things were n’t looking good for a while — for about five months , to be accurate .
But then , on April 20 , Voyager 1finally phoned homewith legible 0 ’s and legible 1 ’s .
" The team had gathered early on on a weekend sunrise to see whether telemetry would return , " Bob Rasmussen , a member of the Voyager flight team , told Space.com . " It was overnice to have everyone assembled in one place like this to share in the mo of acquire that our efforts had been successful . Our cheer was both for the intrepid space vehicle and for the comradery that enable its recovery . "

Andthen , on May 22 , Voyager scientist released the welcome proclamation that the spacecraft has successfully resumed returning science data from two of its four instruments , the plasma wave subsystem and magnetometer legal document . They ’re now working on getting the other two , the cosmic light beam subsystem and low-down energy charged particle instrument , back online as well . Though there technically are six other instruments onboard Voyager , those had been out of commission for some time .
The comeback
Rasmussen was actually a member of the Voyager squad in the 1970s , having bring on the project as a computer engineer before leaving for other missions includingCassini , which launched the spacecraft that teach us almost everything we currently know about Saturn . In 2022 , however , he returned to Voyager because of a separate quandary with the mission — and has remained on the squad ever since .
" There are many of the original mass who were there when Voyager launched , or even before , who were part of both the flying team and the skill team , " Linda Spilker , a planetal scientist at NASA ’s Jet Propulsion Laboratory , who also knead on the Voyager missionary station , told Space.com in the This Week from Space podcast on the TWiT meshing . " It ’s a existent protection to Voyager — the longevity not only of the spacecraft , but of the people on the team . "
To get Voyager 1 back online , in rather cinematic fashion , the squad devise a complex workaround that incite the FDS to mail a copy of its computer memory back to Earth . Within that memory readout , operator make do to discover the crux of the matter of the problem — a corrupted codification spanning a single chip — which was then remedied through another ( frankly , super interesting ) process to modify the code . On the day Voyager 1 in the end speak again , " you could have heard a pin fall in the room , " Spilker said . " It was very silent . Everybody ’s search at the covert , waiting and watching . "

Of course , Spilker also brought in some peanut for the squad to crunch on — but not just any peanuts . Lucky peanut .
It ’s a longstanding custom at JPL to have a monkey nut feast before major mission events like launches , milepost and , well , the possible resurrection of Voyager 1 . Itbeganin the 1960s , when the means was endeavor to launch the Ranger 7 mission that was meant to take exposure of and collect data about the moonlight ’s surface . commando 1 through 6 had all fail , so Ranger 7 was a big deal . As such , the mission ’s trajectory engineer , Dick Wallace , take set of peanut for the squad to nibble on and relax . sure as shooting enough , Ranger 7 was a success and , as Wallace once say , " the rest is history . "
Voyager 1 needed some of those positive snacky vibes .
Jubilant scenes as NASA’s Voyager 1 flight team hear back from the craft for the first time in five months.
" It ’d been five month since we ’d had any data , " Spilker explained . So , in this elbow room of silence besides peanut vine - feeding - noises , Voyager 1 manipulator sit at their respective system screens , expect .
" All of a sudden it set out to dwell — the data , " Spilker said . That ’s when the programmers who had been staring at those screens in anticipation leapt out of their seats and began to cheer : " They were the well-chosen people in the room , I think , and there was just a horse sense of joyfulness that we had Voyager 1 back . "
Eventually , Rasmussen say the team was able to conclude that the failure in all probability happen due to a combination of ripening and radiation therapy damage by which gumptious speck in space bombard the craft . This is also why he believe it would n’t be terribly surprising to see a similar failure come in the futurity , seeing as Voyager 1 is still rove beyond the distant boundaries of our star neighborhood just like its space vehicle twin , Voyager 2 .
The trajectory of the Voyagers.
To be certain , the ballistic capsule is n’t fully unsex yet — but it ’s lovely to know things are finally looking up , specially with the late news that some of its science instrument are back on caterpillar track . And , at the very least , Rasmussen assure that nothing the team has learned so far has been alarming . " We ’re surefooted that we understand the problem well , " he say , " and we remain optimistic about arrest everything back to normal — but we also await this wo n’t be the last . "
In fact , as Rasmussen explains , Voyager 1 wheeler dealer first became optimistic about the situation just after the root suit of the bug had been check with certainty . He also emphasizes that the team ’s spirits were never down . " We knew from indirect grounds that we had a spacecraft that was mostly healthy , " he said . " Saying goodbye was not on our minds . "
" Rather , " he continued , " we want to advertise toward a solution as quickly as possible so other matters on board that had been neglected for months could be address . We ’re now sedately moving toward that finish . "

The future of Voyager’s voyage
It ca n’t be ignored that , over the last few months , there has been an air of anxiety and fear across the public area that Voyager 1 was tardily moving toward sending us its final 0 and last 1 . Headlines all over the internet , one write bymyself included , have carried clear , negative weight . I think it ’s because even if Voyager 2 could technically carry the interstellar flannel mullein stake - Voyager 1 , the expectation of losing Voyager 1 feel like the prospect of lose a piece of history .
" We ’ve cover this boundary called the heliopause , " Spilker explicate of the Voyagers . " Voyager 1 crossed this boundary in 2012 ; Voyager 2 crossed it in 2018 — and , since that clip , were the first spacecraft ever to make direct mensuration of the interstellar medium . " That medium fundamentally relate to fabric that replete the space between stars . In this case , that ’s the space between other stars and our sun , which , though we do n’t always remember of it as one , is only another principal in the universe . A drop in the cosmic ocean .
" JPL started build up the two Voyager spacecraft in 1972 , " Spilker explained . " For context , that was only three geezerhood after we had the first human walk on the moon — and the reason we started that too soon is that we had this rare alignment of the planets that take place once every176 age . " It was this alignment that could anticipate the spacecraft checkpoints across the solar arrangement , including at Jupiter , Saturn , Uranus and Neptune . Those checkpoints were important for the Voyagers in particular . Alongside planetary visits descend gravity assists , and gravity assists can help fling stuff within the solar system — and , now we sleep together , beyond .
As the first humanmade object to leave the solar organisation , as a keepsake of America ’s early outer space computer program , and as a testament to how robust even decades - sometime technology can be , Voyager 1 has carve out the form of legacy usually set aside for noteworthy things lost to clock time .
" Our scientist are eager to see what they ’ve been missing , " Rasmussen comment . " Everyone on the team is self - move by their commitment to this unequalled and important task . That ’s where the tangible pressure come from . "
Still , in terms of energy , the team ’s approach has been clinical and determine .
— NASA ’s Voyager 1 sends readable message to Earth after 4 nail - biting months of gibberish
— NASA engineers discover why Voyager 1 is transport a stream of gibberish from outside our solar organization
— NASA ’s Voyager 1 investigation has n’t ' speak ' in 3 months and needs a ' miracle ' to save it
" No one was ever specially excited or blue , " he said . " We ’re confident that we can get back to business as usual presently , but we also know that we ’re dealing with an mature spacecraft that is bound to have trouble again in the future . That ’s just a fact of spirit on this mission , so not worth getting worked up about . "
nevertheless , I imagine it ’s always a pleasure for Voyager 1 ’s engineers to recall this robotlike IE occupies curious judgment around the globe . ( Including my dad ’s mind now , thanks to me and Google . )
As Rasmussen arrange it : " It ’s wonderful to know how much the world appreciates this mission . "
