What Is on Voyager’s Golden Record?

From a whale song to a kiss, the time capsule sent into space in 1977 had some interesting contents

Megan Gambino

Senior Editor

“I thought it was a brilliant idea from the beginning,” says Timothy Ferris. Produce a phonograph record containing the sounds and images of humankind and fling it out into the solar system.

By the 1970s, astronomers Carl Sagan and Frank Drake already had some experience with sending messages out into space. They had created two gold-anodized aluminum plaques that were affixed to the Pioneer 10 and Pioneer 11 spacecraft. Linda Salzman Sagan, an artist and Carl’s wife, etched an illustration onto them of a nude man and woman with an indication of the time and location of our civilization.

The “Golden Record” would be an upgrade to Pioneer’s plaques. Mounted on Voyager 1 and Voyager 2, twin probes launched in 1977, the two copies of the record would serve as time capsules and transmit much more information about life on Earth should extraterrestrials find it.

NASA approved the idea. So then it became a question of what should be on the record. What are humanity’s greatest hits? Curating the record’s contents was a gargantuan task, and one that fell to a team including the Sagans, Drake, author Ann Druyan, artist Jon Lomberg and Ferris, an esteemed science writer who was a friend of Sagan’s and a contributing editor to Rolling Stone .

The exercise, says Ferris, involved a considerable number of presuppositions about what aliens want to know about us and how they might interpret our selections. “I found myself increasingly playing the role of extraterrestrial,” recounts Lomberg in Murmurs of Earth , a 1978 book on the making of the record. When considering photographs to include, the panel was careful to try to eliminate those that could be misconstrued. Though war is a reality of human existence, images of it might send an aggressive message when the record was intended as a friendly gesture. The team veered from politics and religion in its efforts to be as inclusive as possible given a limited amount of space.

Over the course of ten months, a solid outline emerged. The Golden Record consists of 115 analog-encoded photographs, greetings in 55 languages, a 12-minute montage of sounds on Earth and 90 minutes of music. As producer of the record, Ferris was involved in each of its sections in some way. But his largest role was in selecting the musical tracks. “There are a thousand worthy pieces of music in the world for every one that is on the record,” says Ferris. I imagine the same could be said for the photographs and snippets of sounds.

The following is a selection of items on the record:

Silhouette of a Male and a Pregnant Female

The team felt it was important to convey information about human anatomy and culled diagrams from the 1978 edition of The World Book Encyclopedia. To explain reproduction, NASA approved a drawing of the human sex organs and images chronicling conception to birth. Photographer Wayne F. Miller’s famous photograph of his son’s birth, featured in Edward Steichen’s 1955 “Family of Man” exhibition, was used to depict childbirth. But as Lomberg notes in Murmurs of Earth , NASA vetoed a nude photograph of “a man and a pregnant woman quite unerotically holding hands.” The Golden Record experts and NASA struck a compromise that was less compromising— silhouettes of the two figures and the fetus positioned within the woman’s womb.

DNA Structure

At the risk of providing extraterrestrials, whose genetic material might well also be stored in DNA, with information they already knew, the experts mapped out DNA’s complex structure in a series of illustrations.

Demonstration of Eating, Licking and Drinking

When producers had trouble locating a specific image in picture libraries maintained by the National Geographic Society, the United Nations, NASA and Sports Illustrated , they composed their own. To show a mouth’s functions, for instance, they staged an odd but informative photograph of a woman licking an ice-cream cone, a man taking a bite out of a sandwich and a man drinking water cascading from a jug.

Olympic Sprinters

Images were selected for the record based not on aesthetics but on the amount of information they conveyed and the clarity with which they did so. It might seem strange, given the constraints on space, that a photograph of Olympic sprinters racing on a track made the cut. But the photograph shows various races of humans, the musculature of the human leg and a form of both competition and entertainment.

Photographs of huts, houses and cityscapes give an overview of the types of buildings seen on Earth. The Taj Mahal was chosen as an example of the more impressive architecture. The majestic mausoleum prevailed over cathedrals, Mayan pyramids and other structures in part because Mughal Emperor Shah Jahan built it in honor of his late wife, Mumtaz Mahal, and not a god.

Golden Gate Bridge

Three-quarters of the record was devoted to music, so visual art was less of a priority. A couple of photographs by the legendary landscape photographer Ansel Adams were selected, however, for the details captured within their frames. One, of the Golden Gate Bridge from nearby Baker Beach, was thought to clearly show how a suspension bridge connected two pieces of land separated by water. The hum of an automobile was included in the record’s sound montage, but the producers were not able to overlay the sounds and images.

A Page from a Book

An excerpt from a book would give extraterrestrials a glimpse of our written language, but deciding on a book and then a single page within that book was a massive task. For inspiration, Lomberg perused rare books, including a first-folio Shakespeare, an elaborate edition of Chaucer from the Renaissance and a centuries-old copy of Euclid’s  Elements  (on geometry), at the Cornell University Library. Ultimately, he took MIT astrophysicist Philip Morrison’s suggestion: a  page  from Sir Isaac Newton’s  System of the World , where the means of launching an object into orbit is described for the very first time.

Greeting from Nick Sagan

To keep with the spirit of the project, says Ferris, the wordings of the 55 greetings were left up to the speakers of the languages. In  Burmese , the message was a simple, “Are you well?” In  Indonesian , it was, “Good night ladies and gentlemen. Goodbye and see you next time.” A woman speaking the Chinese dialect of  Amoy  uttered a welcoming, “Friends of space, how are you all? Have you eaten yet? Come visit us if you have time.” It is interesting to note that the final greeting, in  English , came from then-6-year-old Nick Sagan, son of Carl and Linda Salzman Sagan. He said, “Hello from the children of planet Earth.”

Whale Greeting

Biologist Roger Payne provided a whale song (“the most beautiful whale greeting,” he said, and “the one that should last forever”) captured with hydrophones off the coast of Bermuda in 1970. Thinking that perhaps the whale song might make more sense to aliens than to humans, Ferris wanted to include more than a slice and so mixed some of the song behind the greetings in different languages. “That strikes some people as hilarious, but from a bandwidth standpoint, it worked quite well,” says Ferris. “It doesn’t interfere with the greetings, and if you are interested in the whale song, you can extract it.”

Reportedly, the trickiest sound to record was a  kiss . Some were too quiet, others too loud, and at least one was too disingenuous for the team’s liking. Music producer Jimmy Iovine kissed his arm. In the end, the kiss that landed on the record was actually one that Ferris planted on Ann Druyan’s cheek.

Druyan had the idea to record a person’s brain waves, so that should extraterrestrials millions of years into the future have the technology, they could decode the individual’s thoughts. She was the guinea pig. In an hour-long session hooked to an EEG at New York University Medical Center, Druyan meditated on a series of prepared thoughts. In  Murmurs of Earth , she admits that “a couple of irrepressible facts of my own life” slipped in. She and Carl Sagan had gotten engaged just days before, so a love story may very well be documented in her neurological signs. Compressed into a minute-long segment, the  brain waves  sound, writes Druyan, like a “string of exploding firecrackers.”

Georgian Chorus—“Tchakrulo”

The team discovered a beautiful recording of “Tchakrulo” by Radio Moscow and wanted to include it, particularly since Georgians are often credited with introducing polyphony, or music with two or more independent melodies, to the Western world. But before the team members signed off on the tune, they had the lyrics translated. “It was an old song, and for all we knew could have celebrated bear-baiting,” wrote Ferris in  Murmurs of Earth . Sandro Baratheli, a Georgian speaker from Queens, came to the rescue. The word “tchakrulo” can mean either “bound up” or “hard” and “tough,” and the song’s narrative is about a peasant protest against a landowner.

Chuck Berry’s “Johnny B. Goode”

According to Ferris, Carl Sagan had to warm up to the idea of including Chuck Berry’s 1958 hit “Johnny B. Goode” on the record, but once he did, he defended it against others’ objections. Folklorist Alan Lomax was against it, arguing that rock music was adolescent. “And Carl’s brilliant response was, ‘There are a lot of adolescents on the planet,’” recalls Ferris.

On April 22, 1978,  Saturday Night Live  spoofed the Golden Record in a  skit  called “Next Week in Review.” Host Steve Martin played a psychic named Cocuwa, who predicted that  Time  magazine would reveal, on the following week’s cover, a four-word message from aliens. He held up a mock cover, which read, “Send More Chuck Berry.”

More than four decades later, Ferris has no regrets about what the team did or did not include on the record. “It means a lot to have had your hand in something that is going to last a billion years,” he says. “I recommend it to everybody. It is a healthy way of looking at the world.”

According to the writer, NASA approached him about producing another record but he declined. “I think we did a good job once, and it is better to let someone else take a shot,” he says.

So, what would you put on a record if one were being sent into space today?

11 Pieces of Media on the Voyager Golden Record

By michele debczak | apr 11, 2021.

At this moment, two gold-plated copper records are hurtling through space, speeding beyond our solar system. The Voyager 1 and 2 probes launched in 1977 , and they’ve since traveled billions of miles from Earth. They are currently the loneliest human-made objects in the universe—and they may stay that way forever—but they were built to make a connection.

The purpose of NASA ’s Voyager mission is to illustrate life on Earth to any intelligent aliens that come across the spacecraft. The records on board contain media selected by a committee chaired by scientist Carl Sagan. If extraterrestrials can use the instructions engraved on the disc's cover to access its contents, they’ll be exposed to animal noises, classical music, and photographs of people from around the world. Here are some pieces of media that were chosen to represent our planet.

1. Beethoven’s Fifth Symphony

Ludwig van Beethoven is one of many classical artists representing the music of Earth on the Voyager record. In addition to his Fifth Symphony , the composer’s String Quartet No. 13, Opus 130, is also included on the track list.

2. Chuck Berry’s “Johnny B. Goode”

Though there are many musical compositions on the Voyager Golden Record , the inclusion of “Johnny B. Goode” stirred controversy. Critics claimed rock n’ roll was too adolescent for a project of such significance. Carl Sagan responded by saying, “There are a lot of adolescents on the planet.”

3. A Mandarin Greeting and Invitation

The Voyager project recorded UN delegates from around the world saying greetings in 54 different languages. Most are straightforward, but the Mandarin message includes an invitation. Translated to English, it says: "Hope everyone's well. We are thinking about you all. Please come here to visit when you have time."

4. Humpback Whale Songs

The greetings section of the record features one language that doesn’t belong to humans. Interspersed between the spoken audio clips are the sounds of singing humpback whales . There’s a reason whales were included with the greetings rather than the other animal noises on the record—it was the committee’s way of acknowledging that humans aren’t the only intelligent life on Earth.

5. The UN Building

The Voyager committee chose the UN Building to represent modern urban architecture. The record includes two images of the New York City skyscraper, both taken at the same angle. One depicts the structure during the day and the other shows it at night .

6. A Traffic Jam

The Voyager record highlights many technological marvels from the time it was made, including a rocket and an airplane. The photo of a traffic jam in Thailand that was included may seem less impressive, but it accurately depicts how we use cars on our planet.

7. A Bulgarian Folk Song

The Voyager committee wanted the record's music to represent a wide range of eras and cultures. One track, titled "Izlel je Delyo Hagdutin," is a traditional folk song from Bulgaria . Sung by Valya Balkanska, it’s about a famous rebel leader from the country’s history. Folk music from Azerbaijan, Georgia, and the Navajo people also made it onto the compilation.

8. Ann Druyan’s Brainwaves

While working on the Voyager committee, Ann Druyan had the idea to record her brainwaves, turn them into audio, and copy them onto the record. She spent an hour hooked up to electrical impulse-measuring systems while thinking various thoughts, including what it’s like to fall in love. She and Sagan—her collaborator on the Voyager record project—had recently gotten engaged.

9. A Map of the Solar System

The Voyager mission is designed to travel far, but it will always hold evidence of where it came from. One of the images on the record shows a picture of our solar system with a map illustrating Earth’s location.

10. People Eating

Some human behaviors are tricky to capture in one image. To show the different ways people consume food and drink, the Voyager committee included a photo of someone licking ice cream, someone else biting into a sandwich, and a third person pouring water into their mouth.

11. A Morse Code Message

Another type of communication represented on the Voyager record is Morse code . The message translates to the Latin saying ad astra per aspera , or “to the stars through hard work.”

The Voyager Golden Record Finally Finds An Earthly Audience

Alexi Horowitz-Ghazi

The Voyager Golden Record remained mostly unavailable and unheard, until a Kickstarter campaign finally brought the sounds to human ears. Ozma Records/LADdesign hide caption

The Voyager Golden Record remained mostly unavailable and unheard, until a Kickstarter campaign finally brought the sounds to human ears.

The Golden Record is basically a 90-minute interstellar mixtape — a message of goodwill from the people of Earth to any extraterrestrial passersby who might stumble upon one of the two Voyager spaceships at some point over the next couple billion years.

But since it was made 40 years ago, the sounds etched into those golden grooves have gone mostly unheard, by alien audiences or those closer to home.

"The Voyager records are the farthest flung objects that humans have ever created," says Timothy Ferris, a veteran science and music journalist and the producer of the Golden Record. "And they're likely to be the longest lasting, at least in the 20th century."

In the late 1970s, Ferris was recruited by his friend, astronomer Carl Sagan, to join a team of scientists, artists and engineers to help create two engraved golden records to accompany NASA's Voyager mission — which would eventually send a pair of human spacecraft beyond the outer rings of the solar system for the first time in history.

Carl Sagan And Ann Druyan's Ultimate Mix Tape

Ferris was tasked with the technical aspects of getting the various media onto the physical LP, and with helping to select the music. In addition to greetings in dozens of languages and messages from leading statesmen, the records also contained a sonic history of planet Earth and photographs encoded into the record's grooves. But mostly, it was music.

"We were gathering a representation of the music of the entire earth," Ferris says. "That's an incredible wealth of great stuff."

Ferris and his colleagues worked together to sift through Earth's enormous discography to decide which pieces of sound would best represent our planet. They really only had two criteria: "One was: Let's cast a wide net. Let's try to get music from all over the planet," he says. "And secondly: Let's make a good record."

That meant late nights of listening sessions while "almost physically drowning in records," Ferris says.

The final selection, which was engraved in copper and plated in gold, included opera, rock 'n' roll, blues, classical music and field recordings selected by ethnomusicologist Alan Lomax .

When Voyager 1 and its identical sister craft Voyager 2 launched in 1977, each carried a gold record titled T he Sounds Of Earth that contained a selection of recordings of life and culture on Earth. The cover contains instructions for any extraterrestrial being wishing to play the record. NASA/Getty Images hide caption

When Voyager 1 and its identical sister craft Voyager 2 launched in 1977, each carried a gold record titled T he Sounds Of Earth that contained a selection of recordings of life and culture on Earth. The cover contains instructions for any extraterrestrial being wishing to play the record.

Ferris says that from the very start, many people on the production team expected and hoped for the record to be commercially released soon after the launch of Voyager.

"Carl Sagan tried to interest labels in releasing Voyager," Ferris says. "It never worked."

Ferris says that's likely because the music rights were owned by several different record labels who were hesitant to share the bill. So — except for a limited CD-ROM release in the early 1990s — the record went largely unheard by the wider world.

David Pescovitz, an editor at technology news website Boing Boing and a research director at the nonprofit Institute for the Future, was seven years old when the Voyager spacecraft launched.

"When you're seven years old and you hear that a group of people created a phonograph record as a message for possible extraterrestrials and launched it on a grand tour of the solar system," says Pescovitz, "it sparks the imagination."

A couple years ago, Pescovitz and his friend Tim Daly, a record store manager at Amoeba Music in San Francisco, decided to collaborate on bringing the Golden Record to an earthbound audience.

Pescovitz approached his former graduate school professor — none other than Ferris, the Golden Record's original producer — about the project, and Ferris gave his blessing, with one important caveat.

Voyagers' Records Wait for Alien Ears

"You can't release a record without remastering it," says Ferris. "And you can't remaster without locating the master."

That turned out to be a taller order than expected. The original records were mastered in a CBS studio, which was later acquired by Sony — and the master tapes had descended into Sony's vaults.

Pescovitz enlisted the company's help in searching for the master tapes; in the meantime, he and Daly got to work acquiring the rights for the music and photographs that comprised the original. They also reached out to surviving musicians whose work had been featured on the record to update incomplete track information.

Finally, Pescovitz and Daly got word that one of Sony's archivists had found the master tapes.

Pescovitz remembers the moment he, Daly and Ferris traveled to Sony's Battery Studios in New York City to hear the tapes for the first time.

"They hit play, and the sounds of the Solomon Islands pan pipes and Bach and Chuck Berry and the blues washed over us," Pescovitz says. "It was a very moving and sublime experience."

Daly says that, in remastering the album, the team decided not to clean up the analog artifacts that had made their way onto the original master tapes, in order to preserve the record's authenticity down to its imperfections.

"We wanted it to be a true representation of what went up," Daly says.

Pescovitz and Daly teamed up with Lawrence Azerrad, a graphic designer who has made record packaging for the likes of Sting and Wilco , to design a luxuriant box set, complete with a coffee table book of photographs and, of course, tinted vinyl.

"I mean, if you do a golden record box set, you have to do it on gold vinyl," Daly says.

They put the project on Kickstarter and expected to sell it mostly to vinyl collectors, space nerds and audiophiles — but they underestimated the appeal.

"The internet was just on fire, talking about this thing," Daly says.

They blew past their initial funding goal in two days, eventually raising more than $1.3 million dollars, making it the most successful musical Kickstarter campaign ever. Among the initial 11,000 contributors were family members of NASA's original Voyager mission team.

An Alien View Of Earth

Last week, Ferris got his box set in the mail. He says that his friend, the late Carl Sagan, would be delighted by what they made.

"I think this record exceeds Carl's — not only his expectations, but probably his highest hopes for a release of the Voyager record," Ferris says. "I'm glad these folks were finally able to make it happen."

Pescovitz says he's just glad to have returned the Golden Record to the world that created it.

At a moment of political division and media oversaturation, Pescovitz and Daly say they hope that their Golden Record can offer a chance for people to slow down for a moment; to gather around the turntable and bask in the crackly sounds of what Sagan called the "pale blue dot" that we call home.

"As much as it was a gift from humanity to the cosmos, it was really a gift to humanity as well," Pescovitz says. "It's a reminder of what we can accomplish when we're at our best."

Nasa space probe that’s been sending mysterious messages for FIVE months is fixed – but a key issue remains

• Millie Turner , Technology & Science Reporter
• Published : 11:26 ET, Apr 23 2024
• Published : Invalid Date,

NASA has finally reconnected with its Voyager 1 probe after a mysterious five month blackout, the US space agency has announced.

The Voyager 1 probe – the most distant man-made object in the Universe – is now returning readable information to ground control.

It had previously been sending through incoherent information - and scientists were not sure why.

The spacecraft stopped sending readable data back to Earth on November 14, 2023.

But mystery stuck when controllers realised the spacecraft was still receiving their commands.

In March, Nasa's Jet Propulsion Laboratory found that chip malfunction was to blame, and rushed to provide a fix.

After issuing a coding fix to the faulty chip, Voyager 1 is back up and running again.

However, scientists still have to figure out how to begin receiving science data again.

"Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems," the agency  said in a statement.

"The next step is to enable the spacecraft to begin returning science data again."

The golden records.

The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space, according to Nasa.

In January 2024, Voyager 1 reached 15 billion miles - or about 136 AU - from Earth.

Both Voyager spacecraft carry "Golden Records" – 12-inch, gold-plated copper disks intended to convey the story of human beings and our world to any alien life that might find it.

According to Nasa, "The records also contain instructions to play them using a cartridge and a needle, much like a vinyl record player.

"The audio on the disc includes greetings in 55 languages, 35 sounds from life on Earth (such as whale songs, laughter, etc.), 90 minutes of generally Western music including everything from Mozart and Bach to Chuck Berry and Blind Willie Johnson.

"It also includes 115 images of life on Earth and recorded greetings from then U.S. President Jimmy Carter (1924– ) and then-UN Secretary-General Kurt Waldheim (1918–2007)."

'It was tremendously exciting': NASA re-establishes communication with Voyager 1

For the first time in five months, NASA has received decipherable-data from Voyager 1.

Voyager project scientist Linda Spilker said one of the computer chips in the memory had failed.

“It was a hardware failure and so we had to reprogram around that bit of memory, moving that piece of code to a different place and then starting it up again. So last Saturday we got data back again from Voyager 1,” she said in an interview with CTV's Bruce Frisko on Wednesday.

“It was tremendously exciting. I was all smiles. People were high-fiving and cheering and also a relief to be once again communicating with Voyager 1. The next step is to continue that reprograming effort so we can get the science data back.”

Voyager 1 and Voyager 2 launched in 1977. After achieving their primary goals of flying by and exploring the four outer planets of Jupiter, Saturn, Uranus and Neptune, the spacecraft’s are now providing data on interstellar space.

“Basically interstellar space is made up of explosions from stars and super nova explosions that send their material into space,” said Spilker. “So Voyager now for the first time is sampling that material. So it’s very exciting to be exploring in a place that no spacecraft has ever explored before.”

Spilker said each Voyager sends back eight to ten hours of data each day and will eventually run out of power.

“Eventually there won’t be enough power to run the systems on Voyager. We will start to turn the science instruments off one by one and slowly they will be so little power that they will get really cold and that will be the end of the Voyager mission as far as sending back data,” she said.

According to Spilker, each Voyager carries a golden record that has pictures, music and the sights and sounds form the Earth.

“So we sent a galactic message in a bottle out to whoever might find it and there’s even a diagram on the cover of where we are so they can come find us,” she said.

“I think that Voyager has taught us that there are a lot of amazing surprises out there and that there is still a lot to learn.”

After months of silence, Voyager 1 has returned NASA’s calls

• Show more sharing options

For the last five months, it seemed very possible that a 46-year-old conversation had finally reached its end.

Since its launch from Kennedy Space Center on Sept. 5, 1977, NASA’s Voyager 1 spacecraft has diligently sent regular updates to Earth on the health of its systems and data collected from its onboard instruments.

But in November, the craft went quiet.

Voyager 1 is now some 15 billion miles away from Earth. Somewhere in the cold interstellar space between our sun and the closest stars, its flight data system stopped communicating with the part of the probe that allows it to send signals back to Earth. Engineers at the Jet Propulsion Laboratory in La Cañada Flintridge could tell that Voyager 1 was getting its messages, but nothing was coming back.

“We’re to the point where the hardware is starting to age,” said Linda Spilker, the project scientist for the Voyager mission. “It’s like working on an antique car, from 15 billion miles away.”

Week after week, engineers sent troubleshooting commands to the spacecraft, each time patiently waiting the 45 hours it takes to get a response here on Earth — 22.5 hours traveling at the speed of light to reach the probe, and 22.5 hours back.

This space artist created the Golden Record and changed the way we see the universe

Space artist Jon Lomberg has produced work that attempts to visualize what we can’t truly see, and to communicate with creatures we can’t yet imagine.

July 26, 2023

By March, the team had figured out that a memory chip that stored some of the flight data system’s software code had failed, turning the craft’s outgoing communications into gibberish.

A long-distance repair wasn’t possible. There wasn’t enough space anywhere in the system to shift the code in its entirety. So after manually reviewing the code line by line, engineers broke it up and tucked the pieces into the available slots of memory.

They sent a command to Voyager on Thursday. In the early morning hours Saturday, the team gathered around a conference table at JPL: laptops open, coffee and boxes of doughnuts in reach.

At 6:41 a.m., data from the craft showed up on their screens. The fix had worked .

“We went from very quiet and just waiting patiently to cheers and high-fives and big smiles and sighs of relief,” Spilker said. “I’m very happy to once again have a meaningful conversation with Voyager 1.”

Voyager 1 is one of two identical space probes. Voyager 2, launched two weeks before Voyager 1, is now about 13 billion miles from Earth, the two crafts’ trajectories having diverged somewhere around Saturn. (Voyager 2 continued its weekly communications uninterrupted during Voyager 1’s outage.)

They are the farthest-flung human-made objects in the universe, having traveled farther from their home planet than anything else this species has built. The task of keeping communications going grows harder with each passing day. Every 24 hours, Voyager 1 travels 912,000 miles farther away from us. As that distance grows, the signal becomes slower and weaker.

When the probe visited Jupiter in 1979, it was sending back data at a rate of 115.2 kilobits per second, Spilker said. Today, 45 years and more than 14 billion miles later, data come back at a rate of 40 bits per second.

The team is cautiously optimistic that the probes will stay in contact for three more years, long enough to celebrate the mission’s 50th anniversary in 2027, Spilker said. They could conceivably last until the 2030s.

The conversation can’t last forever. Microscopic bits of silica keep clogging up the thrusters that keep the probes’ antennas pointed toward Earth, which could end communications. The power is running low. Eventually, the day will come when both Voyagers stop transmitting data to Earth, and the first part of their mission ends.

But on the day each craft goes quiet, they begin a new era, one that could potentially last far longer. Each probe is equipped with a metallic album cover containing a Golden Record , a gold-plated copper disk inscribed with sounds and images meant to describe the species that built the Voyagers and the planet they came from.

Erosion in space is negligible; the images could be readable for another billion years or more. Should any other intelligent life form encounter one of the Voyager probes and have a means of retrieving the data from the record, they will at the very least have a chance to figure out who sent them — even if our species is by that time long gone.

NASA's Voyager is in hostile territory. It's 'dodging bullets.'

NASA's Voyager craft have ventured where no other human machines have ever gone — the space between the stars. But that comes with a cost.

At some 15 and 12 billion miles away, Voyager 1 and 2 are beyond the protective bubble of the sun , called the heliosphere. Out in this realm of interstellar space , the nearly 50-year-old probes have a higher probability of damage from hostile, high-speed particles, called galactic cosmic rays, owing to a higher number of particles zooming by every second.

"We are dodging bullets out there," Alan Cummings, a cosmic-ray physicist at Caltech — the research university that manages NASA's Jet Propulsion Laboratory — told Mashable. Cummings began working on the Voyager mission 51 years ago.

But direct hits are inevitable. In 2010, while on the edge of our solar system's heliosphere, Voyager 2 unexpectedly began sending gibberish back to Earth . Cummings suspects that a passing galactic cosmic ray tripped part of a computer's memory — though NASA was eventually able to rectify the problem. Most recently, Voyager 1 failed to send back readable data for five months , a particularly worrying incident that may also have been triggered by a cosmic ray. Something corrupted a computer chip.

"We don't know everything," Cummings explained, referencing the difficulty in perfectly diagnosing such profoundly distant mishaps. "But I do think galactic cosmic rays are the guilty party here for most of these problems."

"We are dodging bullets out there."

Galactic cosmic rays are merciless because they're extremely tiny, charged particles, traveling at incredible speeds — nearly the speed of light. "The galaxy is permeated with galactic cosmic rays," Cummings marveled. Astronomers think violently exploding stars — supernovae — are responsible for creating many of these particles, as the colossal shock wave from the event accelerates the particles. Stripped of their outer shells, they hurtle through space as just the nuclei of atoms.

The heavier ones, like iron atoms transformed into galactic cosmic rays, can cause more damage than the lighter, more abundant ones. (It's somewhat like getting hit by a bowling ball at 50 mph, versus a golf ball.) They can zip right through a computer chip — altering its code — or even become lodged there, where they can pack an even bigger punch by doing permanent damage.

Of course, NASA spacecraft like the Voyagers are equipped with radiation-resistant parts and shielding, including wrapping around critical cables. These layers can keep out some particles — but not all. "You can protect yourself to some extent, but a high-enough-energy particle will get through your defenses," Cummings explained. Early in the Voyager mission, the space agency's engineers were worried about the craft passing by Jupiter , a planet that produces intense radiation. A person hypothetically riding aboard Voyager would have gotten hit with a radiation dose 1,000 times the lethal level . "That was pretty hostile," Cummings recalled. He said a few detectors on his galactic-ray measuring instrument (the Cosmic Ray Subsystem) were wounded, but overall, both the instrument and entire spacecraft survived to produce new scientific results, including vibrant, unprecedented imagery.

Yet out in the deeper cosmos, the Voyagers face a different threat. Around the gas giant Jupiter, the craft were sprayed with charged particles, but they were lower energy. Now in interstellar space, the craft are more often exposed to those high-energy particles. Any place in space — whether in our solar system or beyond — can meet the threat of a harmful galactic cosmic ray. But the odds are boosted in the interstellar realm.

"Explorers run into problems when they enter into new territory."

When might another such hit come? "It's just a random chance out there right now," Cummings said.

Billions of miles away, on Earth, in sunny Pasadena, California, however, the craft have a guardian. Or, a legion of guardians. NASA engineers have for decades devised ways to keep the aging, radiation-pummeled craft alive. They communicate with vintage computers aboard the nearly half-century old probes. Talking to an interstellar craft isn't like sending a text: It takes almost two days to transmit and then receive a message. Most recently, in April, NASA engineers squared off with a permanently-damaged computer chip on Voyager 1. By beaming messages to the craft, over 15 billion miles away, they successfully stored the defunct chip's unique code in other chips, as "no single location is large enough to hold the section of code in its entirety," the agency explained. The craft is once again communicating about its health, but not yet returning science data.

"You have to praise the engineers," Cummings emphasized.

They've certainly been busy. And in hostile space, with high-speed particles ceaselessly whizzing by, they'll likely continue to be. The craft are running low on nuclear fuel, but could — if undamaged — beam back unprecedented readings from uncharted space through the mid-2030s .

"Explorers run into problems when they enter into new territory," Cummings said. "Lewis and Clark didn't have an easy time, either."

National news | cal poly humboldt closes campus for rest of semester over gaza protests, national news, national news | voyager 1 sending data to earth for 1st time in 5 months, “today was a great day for voyager 1. we’re back in communication with the spacecraft.”.

By Ashley Strickland | CNN

For the first time in five months, NASA engineers have received decipherable data from Voyager 1 after crafting a creative solution to fix a communication problem aboard humanity’s most distant spacecraft in the cosmos.

Voyager 1 is currently about 15 billion miles (24 billion kilometers) away, and at 46 years old, the probe has shown multiple quirks and signs of aging in recent years.

The latest issue experienced by Voyager 1 first cropped up in November 2023, when the flight data system’s telemetry modulation unit began sending an indecipherable repeating pattern of code .

Voyager 1’s flight data system collects information from the spacecraft’s science instruments and bundles it with engineering data that reflects its current health status. Mission control on Earth receives that data in binary code, or a series of ones and zeroes.

But since November, Voyager 1’s flight data system had been stuck in a loop. While the probe has continued to relay a steady radio signal to its mission control team on Earth over the past few months, the signal did not carry any usable data.

The mission team received the first coherent data about the health and status of Voyager 1’s engineering systems on April 20. While the team is still reviewing the information, everything they’ve seen so far suggests Voyager 1 is healthy and operating properly.

“Today was a great day for Voyager 1,” said Linda Spilker, Voyager project scientist at JPL, in a statement Saturday. “We’re back in communication with the spacecraft. And we look forward to getting science data back.”

The breakthrough came as the result of a clever bit of trial and error and the unraveling of a mystery that led the team to a single chip.

Troubleshooting from billions of miles away

After discovering the issue, the mission team attempted sending commands to restart the spacecraft’s computer system and learn more about the underlying cause of the problem.

The team sent a command called a “poke” to Voyager 1 on March 1 to get the flight data system to run different software sequences in the hopes of finding out what was causing the glitch.

On March 3, the team noticed that activity from one part of the flight data system stood out from the rest of the garbled data. While the signal wasn’t in the format the Voyager team is used to seeing when the flight data system is functioning as expected, an engineer with NASA’s Deep Space Network was able to decode it.

The Deep Space Network is a system of radio antennae on Earth that help the agency communicate with the Voyager probes and other spacecraft exploring our solar system.

The decoded signal included a readout of the entire flight data system’s memory.

By investigating the readout, the team determined the cause of the issue: 3% of the flight data system’s memory is corrupted . A single chip responsible for storing part of the system’s memory, including some of the computer’s software code, isn’t working properly. While the cause of the chip’s failure is unknown, it could be worn out or may have been hit by an energetic particle from space, the team said.

The loss of the code on the chip caused Voyager 1’s science and engineering data to be unusable.

Since there was no way to repair the chip, the team opted to store the affected code from the chip elsewhere in the system’s memory. While they couldn’t pinpoint a location large enough to hold all of the code, they were able to divide the code into sections and store it in different spots within the flight data system.

“To make this plan work, they also needed to adjust those code sections to ensure, for example, that they all still function as a whole,” according to an update from NASA . “Any references to the location of that code in other parts of the (flight data system) memory needed to be updated as well.”

After determining the code necessary for packaging Voyager 1’s engineering data, engineers sent a radio signal to the probe commanding the code to a new location in the system’s memory on April 18.

Given Voyager 1’s immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.

On April 20, the team received Voyager 1’s response indicating that the clever code modification had worked, and they could finally receive readable engineering data from the probe once more.

Exploring interstellar space

Within the coming weeks, the team will continue to relocate other affected parts of the system’s software, including those responsible for returning the valuable science data Voyager 1 is collecting.

Initially designed to last five years, the Voyager 1 and its twin, Voyager 2, launched in 1977 and are the longest operating spacecraft in history. Their exceptionally long life spans mean that both spacecraft have provided additional insights about our solar system and beyond after achieving their preliminary goals of flying by Jupiter, Saturn, Uranus and Neptune decades ago.

The probes are currently venturing through uncharted cosmic territory along the outer reaches of the solar system. Both are in interstellar space and are the only spacecraft ever to operate beyond the heliosphere, the sun’s bubble of magnetic fields and particles that extends well beyond the orbit of Pluto.

Voyager 2, which is operating normally, has traveled more than 12.6 billion miles (20.3 billion kilometers) from our planet.

Over time, both spacecraft have encountered unexpected issues and dropouts, including a seven-month period in 2020 when Voyager 2 couldn’t communicate with Earth. In August 2023, the mission team used a long-shot “shout” technique to restore communications with Voyager 2 after a command inadvertently oriented the spacecraft’s antenna in the wrong direction.

The team estimates it’s a few weeks away from receiving science data from Voyager 1 and looks forward to seeing what that data contains.

“We never know for sure what’s going to happen with the Voyagers, but it constantly amazes me when they just keep going,” said Voyager Project Manager Suzanne Dodd, in a statement. “We’ve had many anomalies, and they are getting harder. But we’ve been fortunate so far to recover from them. And the mission keeps going. And younger engineers are coming onto the Voyager team and contributing their knowledge to keep the mission going.”

Inside NASA's 5-month fight to save the Voyager 1 mission in interstellar space

After working for five months to re-establish communication with the farthest-flung human-made object in existence, NASA announced this week that the Voyager 1 probe had finally phoned home.

For the engineers and scientists who work on NASA’s longest-operating mission in space, it was a moment of joy and intense relief.

“That Saturday morning, we all came in, we’re sitting around boxes of doughnuts and waiting for the data to come back from Voyager,” said Linda Spilker, the project scientist for the Voyager 1 mission at NASA’s Jet Propulsion Laboratory in Pasadena, California. “We knew exactly what time it was going to happen, and it got really quiet and everybody just sat there and they’re looking at the screen.”

When at long last the spacecraft returned the agency’s call, Spilker said the room erupted in celebration.

“There were cheers, people raising their hands,” she said. “And a sense of relief, too — that OK, after all this hard work and going from barely being able to have a signal coming from Voyager to being in communication again, that was a tremendous relief and a great feeling.”

The problem with Voyager 1 was first detected in November . At the time, NASA said it was still in contact with the spacecraft and could see that it was receiving signals from Earth. But what was being relayed back to mission controllers — including science data and information about the health of the probe and its various systems — was garbled and unreadable.

That kicked off a monthslong push to identify what had gone wrong and try to save the Voyager 1 mission.

Spilker said she and her colleagues stayed hopeful and optimistic, but the team faced enormous challenges. For one, engineers were trying to troubleshoot a spacecraft traveling in interstellar space , more than 15 billion miles away — the ultimate long-distance call.

“With Voyager 1, it takes 22 1/2 hours to get the signal up and 22 1/2 hours to get the signal back, so we’d get the commands ready, send them up, and then like two days later, you’d get the answer if it had worked or not,” Spilker said.

The team eventually determined that the issue stemmed from one of the spacecraft’s three onboard computers. Spilker said a hardware failure, perhaps as a result of age or because it was hit by radiation, likely messed up a small section of code in the memory of the computer. The glitch meant Voyager 1 was unable to send coherent updates about its health and science observations.

NASA engineers determined that they would not be able to repair the chip where the mangled software is stored. And the bad code was also too large for Voyager 1's computer to store both it and any newly uploaded instructions. Because the technology aboard Voyager 1 dates back to the 1960s and 1970s, the computer’s memory pales in comparison to any modern smartphone. Spilker said it’s roughly equivalent to the amount of memory in an electronic car key.

The team found a workaround, however: They could divide up the code into smaller parts and store them in different areas of the computer’s memory. Then, they could reprogram the section that needed fixing while ensuring that the entire system still worked cohesively.

That was a feat, because the longevity of the Voyager mission means there are no working test beds or simulators here on Earth to test the new bits of code before they are sent to the spacecraft.

“There were three different people looking through line by line of the patch of the code we were going to send up, looking for anything that they had missed,” Spilker said. “And so it was sort of an eyes-only check of the software that we sent up.”

The hard work paid off.

NASA reported the happy development Monday, writing in a post on X : “Sounding a little more like yourself, #Voyager1.” The spacecraft’s own social media account responded , saying, “Hi, it’s me.”

So far, the team has determined that Voyager 1 is healthy and operating normally. Spilker said the probe’s scientific instruments are on and appear to be working, but it will take some time for Voyager 1 to resume sending back science data.

Voyager 1 and its twin, the Voyager 2 probe, each launched in 1977 on missions to study the outer solar system. As it sped through the cosmos, Voyager 1 flew by Jupiter and Saturn, studying the planets’ moons up close and snapping images along the way.

Voyager 2, which is 12.6 billion miles away, had close encounters with Jupiter, Saturn, Uranus and Neptune and continues to operate as normal.

In 2012, Voyager 1 ventured beyond the solar system , becoming the first human-made object to enter interstellar space, or the space between stars. Voyager 2 followed suit in 2018.

Spilker, who first began working on the Voyager missions when she graduated college in 1977, said the missions could last into the 2030s. Eventually, though, the probes will run out of power or their components will simply be too old to continue operating.

Spilker said it will be tough to finally close out the missions someday, but Voyager 1 and 2 will live on as “our silent ambassadors.”

Both probes carry time capsules with them — messages on gold-plated copper disks that are collectively known as The Golden Record . The disks contain images and sounds that represent life on Earth and humanity’s culture, including snippets of music, animal sounds, laughter and recorded greetings in different languages. The idea is for the probes to carry the messages until they are possibly found by spacefarers in the distant future.

“Maybe in 40,000 years or so, they will be getting relatively close to another star,” Spilker said, “and they could be found at that point.”

Inside NASA's 5-month fight to save the Voyager 1 mission in interstellar space

After working for five months to re-establish communication with the farthest-flung human-made object in existence, NASA announced this week that the Voyager 1 probe had finally phoned home.

For the engineers and scientists who work on NASA’s longest-operating mission in space, it was a moment of joy and intense relief.

“That Saturday morning, we all came in, we’re sitting around boxes of doughnuts and waiting for the data to come back from Voyager,” said Linda Spilker, the project scientist for the Voyager 1 mission at NASA’s Jet Propulsion Laboratory in Pasadena, California. “We knew exactly what time it was going to happen, and it got really quiet and everybody just sat there and they’re looking at the screen.”

When at long last the spacecraft returned the agency’s call, Spilker said the room erupted in celebration.

“There were cheers, people raising their hands,” she said. “And a sense of relief, too — that OK, after all this hard work and going from barely being able to have a signal coming from Voyager to being in communication again, that was a tremendous relief and a great feeling.”

The problem with Voyager 1 was first detected in November . At the time, NASA said it was still in contact with the spacecraft and could see that it was receiving signals from Earth. But what was being relayed back to mission controllers — including science data and information about the health of the probe and its various systems — was garbled and unreadable.

That kicked off a monthslong push to identify what had gone wrong and try to save the Voyager 1 mission.

Spilker said she and her colleagues stayed hopeful and optimistic, but the team faced enormous challenges. For one, engineers were trying to troubleshoot a spacecraft traveling in interstellar space , more than 15 billion miles away — the ultimate long-distance call.

“With Voyager 1, it takes 22 1/2 hours to get the signal up and 22 1/2 hours to get the signal back, so we’d get the commands ready, send them up, and then like two days later, you’d get the answer if it had worked or not,” Spilker said.

The team eventually determined that the issue stemmed from one of the spacecraft’s three onboard computers. Spilker said a hardware failure, perhaps as a result of age or because it was hit by radiation, likely messed up a small section of code in the memory of the computer. The glitch meant Voyager 1 was unable to send coherent updates about its health and science observations.

NASA engineers determined that they would not be able to repair the chip where the mangled software is stored. And the bad code was also too large for Voyager 1's computer to store both it and any newly uploaded instructions. Because the technology aboard Voyager 1 dates back to the 1960s and 1970s, the computer’s memory pales in comparison to any modern smartphone. Spilker said it’s roughly equivalent to the amount of memory in an electronic car key.

The team found a workaround, however: They could divide up the code into smaller parts and store them in different areas of the computer’s memory. Then, they could reprogram the section that needed fixing while ensuring that the entire system still worked cohesively.

That was a feat, because the longevity of the Voyager mission means there are no working test beds or simulators here on Earth to test the new bits of code before they are sent to the spacecraft.
