NASA's Voyager probes have been traveling through space for nearly 46 years. Here are 18 groundbreaking photos from their incredible mission.

• Nearly 46 years after their launch, Voyager 1 and 2 will likely soon reach the end of their scientific mission . 
• NASA recently lost contact with Voyager 2 after sending it a bad command by mistake. 
• Here are 18 pictures the probes took over the course of their forty-plus-year journey. 

The Voyager probes are pioneers of science, making it farther into space than any other manufactured object. But now, they face a terminal problem: their power is running out.

The twin probes were originally sent on a four-year mission to tour the solar system, but they exceeded all expectations and are still going nearly 46 years later. That makes them NASA's longest-lived mission.

Scientists are now doing their best to  keep the probes going for as long as possible. They recently found a clever hack to extend Voyager 2's life for another three years and plan to do the same with Voyager 1.

But these are old machines and NASA is constantly scrambling to fix mistakes. Last year, Voyager 1 started sending garbled data from the outside of the solar system. NASA ultimately figured out one of its computers had gone dead.

Voyager 2 is now in limbo , as the agency revealed Friday it had lost contact with the probe when someone sent a wrong command. It could be the end of Voyager 2's mission if NASA can't fix the mistake, which the agency probably won't be able to do before October.

As the probes are nearing the end of their scientific mission, here are 18 images from Voyager that changed science.

The Voyager probes were designed to visit Jupiter and Saturn.

The Voyager mission included two probes — Voyager 1 and Voyager 2 — which NASA launched in 1977 within a few months of each other.

NASA took advantage of a rare planet alignment to turbocharge their journeys into space.

NASA originally built the probes to last five years, but they have exceeded that lifespan many times .

As of August 20 and September 5, 2023, Voyager 2 and Voyager 1 will have been traveling for 46 years, respectively. 

This is what Voyager 1 saw on its approach to Jupiter.

Voyager 1 and Voyager 2 reached Jupiter in 1979.

As they flew by the planet, they took about 50,000 pictures of Jupiter. These blew away scientists, as the quality of the pictures was much better than those taken from Earth, according to NASA.

These snaps  taught scientists important facts about the planet's atmosphere, magnetic forces, and geology that would have been difficult to decipher otherwise.

The probes discovered two new moons orbiting Jupiter: Thebe and Metis.

They also spotted a thin ring around Jupiter.

The probe captured this picture as it was looking back at the planet backlit by the Sun. 

Voyager 1 discovered volcanoes at the surface of Io, one of Jupiter's moons.

Next stop: Saturn.

In 1980 and 1981, the probes reached Saturn . The flyby gave scientists unprecedented insight into the planet's ring structure, atmosphere, and moons.

Voyager snapped Saturn's rings in more detail than ever before.

And showed every secret that Enceladus, Saturn's moon, had to offer.

Saturn, snapped as the probe flew away, was shown in a new light.

By 1986, Voyager 2 had made it to Uranus.

By 1986, Voyager 1 has finished its grand tour of the solar system, and few out towards space. But Voyager 2 kept on its exploring our nearest planets, passing 50,600 miles away from Uranus in January 1986. 

Voyager 2 discovered two extra rings around Uranus , revealing the planet had at least 11, not 9. 

Voyager 2 also spotted 11 previously unseen moons around Uranus.

Here is a picture of Miranda, Uranus's sixth-biggest moon.

Voyager 2 was the first spacecraft to observe Neptune from a close distance.

In 1989, 12 years after its launch, Voyager 2 passed within 3,000 miles of Neptune. 

Here's Nepture taken by Voyager 2, in all its blue glory.

Voyager 2 took this unflattering pic of Triton's rough face.

It captured Triton, Neptune's moon in unprecedented detail. 

And snapped Triton's southern hemisphere.

As it flew by, Voyager 2 uncovered Neptune's rings.

As its parting gift, Voyager 2 took this beautiful picture of light grazing Neptune's south pole.

This is Voyager 2's last picture. Since it wouldn't come across another planet on its ongoing journey, NASA switched off its cameras after its flyby of Neptune to conserve energy for other instruments. 

Voyager 1 had one last trick up its sleeve.

As its last photographic hurrah in 1990, Voyager 1 took 60 images of the solar system from 4 billion miles away.

It gave us the Earth's longest selfie, dubbed the "pale blue dot."

This remains the longest-range selfie: a portrait of the Earth taken by a human-made probe from 4 billion miles away. 

After this picture, NASA switched off Voyager 1's cameras to save energy. NASA could switch the probes' cameras back on , but it is not a priority for the mission. 

Beyond the solar system

Though the probes are no longer sending pictures, they haven't stopped sending crucial information about space. 

In 2012, Voyager 1 became the first human-made instrument to cross into interstellar space by crossing the boundary between our solar system and the rest of the universe, called the heliopause. 

Voyager 2 was second, crossing that threshold in 2018 . The probe revealed that there was yet another  layer outside of our heliosphere.

The probes keep sending back measurements from interstellar space, like weird hums likely coming from vibrations made by neighboring stars.

Even after their instruments are switched off, the probes' mission continues.

NASA is planning to switch more of the probes' instruments in the hope of extending their life to the 2030s.

But even after all their instruments become quiet, their mission will carry on. As they drift off, they will still be carrying a golden record that carries crucial information about humanity. If intelligent extraterrestrial life exists, they could use that information to reach out to us.

After months of sending gibberish to NASA, Voyager 1 is finally making sense again

NASA's Voyager 1 probe has resumed sending usable data back to Earth after engineers fixed a computer error that caused the interstellar spacecraft to only transmit gibberish for five months.

NASA's Voyager 1 probe is once again sending readable radio signals back to Earth after engineers fixed a computer glitch that caused the spacecraft to malfunction in November .

For the first time in five months, Voyager 1 is now transmitting usable data about the health and status of its onboard engineering systems back to our planet, NASA's Jet Propulsion Laboratory announced Monday (April 22). However, engineers have yet to fix the software that enables the spacecraft to return science data.

Voyager 1 is cruising through interstellar space roughly 15 billion miles (24 billion kilometers) away from Earth, which means mission control teams have to wait 22.5 hours for their commands to reach the spacecraft and another 22.5 hours for a response. Voyager 1 and its twin probe — Voyager 2, which continues to operate normally after a 2-week blackout last year — were launched almost 47 years ago and are the most distant human-made objects in existence. 

Engineers first noticed something wrong with Voyager 1 on Nov. 14, 2023, when the probe suddenly began transmitting a nonsensical stream of ones and zeros instead of its usual neatly packaged science and engineering datasets. 

Mission controllers could tell the spacecraft was still receiving their commands, however, indicating that its vital systems were operating normally.

In early March, after three months of unsuccessful tinkering , NASA engineering teams determined the issue was tied to one of Voyager 1's three onboard computer systems known as the "flight data subsystem" (FDS). The FDS is essential for packaging data harvested by the probe before they are sent to Earth, according to NASA's announcement.

Engineers located the glitch by sending a command — or "poke" — that prompted the FDS to try new sequences of code in its software in case the issue could be resolved by skirting a corrupted section. The command triggered a signal that differed from the stream of gibberish the spacecraft had been sending back, and that engineers were able to decode . 

It turned out a single chip responsible for storing a portion of the FDS memory, including some of its computer software code, had stopped working. The loss of that code meant the probe's science and engineering data were unusable, according to NASA. To get around the issue, engineers broke up the code once stored in the chip and squeezed sections of it into functioning portions of the FDS memory.

— Uranus and Neptune aren't made of what we thought, new study hints  

The team then rewrote some of the reshuffled code so it could work as a whole again.

Engineers saved these modifications to the FDS memory on April 18. Two days later, they received a response from Voyager 1 showing that the reshuffle worked. For the first time in five months, the probe's message contained readable data, prompting celebrations at the Jet Propulsion Laboratory in Southern California.

However, solving the spacecraft's science data transmission will take further mending of the corrupted portions of the FDS software, NASA said in its announcement.

Neptune from Voyager

Jónsson describes the processing required to make this as-true-as-possible-color view of Neptune from Voyager data:

I reprojected everything to simple cylindrical projection, aligning the color channels there (i.e. in effect rotating them around Neptune's axis of rotation) and then rendering the map on an ellipsoid without applying any illumination, instead making Neptune self-illuminating. Following this the limb and terminator didn't have realistic color because the three images were obtained over a period of 18 minutes due to the need to transmit them to Earth in real time. I fixed this by making a "regular" color composite (the features near the center of the disk looked horrible in that one) and then "cloning" the color from the limb and terminator in that version to the rendered image. This combined the best features of both versions of the color composite. This I did using Photoshop. This was followed by fairly extensive manual cleanup ecause there were still some spurious features present due to noise in the source images. So this is a very heavily processed image. I then altered the color balance a bit by making a synthetic red image; this made the image a bit more blue. This step was necessary because Voyager's vidicon cameras were not sensitive to light beyond orange wavelengths. The final step was to make the bright clouds around the Great Dark Spot a bit more white. These two steps were somewhat arbitrary but using various other images as a guide (Hubble images of both Uranus and Neptune and the Voyager 2 Uranus-Neptune color difference) I think this significantly improved the color balance. I'm pretty sure this is more realistic than most of the "official" images - the blue color must be too strong and saturated in them. Also most of the official images were made from only two source images, often green and clear. The final step would usually have been to sharpen the images slightly but in this case doing so brings out too much noise in my opinion. It would be an interesting future project to make a 2x2 color mosaic of Neptune but I'm not even sure it's possible due to the long time it took to acquire the required images. So making a high resolution global map and rendering that from any angle might be the only way to get higher resolution global "images."

Pale Blue Dot at 30: Voyager 1's iconic photo of Earth from space reveals our place in the universe

The photo shows Earth as it truly is — a lonely outpost of life in an incomprehensibly vast cosmos.

Thirty years ago today, humanity got a chance to see itself in a whole new light. 

On Feb. 14, 1990, NASA's Voyager 1 probe snapped a photo of Earth from 3.7 billion miles (6 billion kilometers) away. The image shows our home planet as it truly is — a tiny, lonely outpost of life in an incomprehensibly vast cosmos — and became iconic as a result. 

The Voyager 1 team sensed at the time that the " Pale Blue Dot ," as the photo has come to be known, would be an important social document, said planetary scientist Candy Hansen, who served as the experiment representative for the Voyager imaging team and was the first person to set eyes on the Pale Blue Dot photo when it came down to Earth.

The Cold War had not yet thawed completely in early 1990. The Pale Blue Dot had the potential to remind folks around the world that we're all in this together, no matter how many nuclear warheads one superpower may be aiming at another, Hansen explained. And the image remains vital today, because its message is timeless, she added.

"Now, we have climate change as an existential threat," Hansen, who now works for the Arizona-based Planetary Science Institute, told Space.com. "And we need to remind ourselves again that there's one planet that is hospitable to humans. Even if we colonize the moon or Mars one day, neither one of those bodies is really going to be able to support seven billion of us. So, we need to take care of this planet."

A family portrait

Voyager 1 launched a few weeks after its twin, Voyager 2 , back in 1977. Together, the two probes conducted an unprecedented "grand tour" of the solar system's giant planets, flying by Jupiter, Saturn, Uranus and Neptune.

The tour was over after the Neptune encounter, which Voyager 2 executed in August 1989. But the two spacecraft kept on flying, out toward the great unknown of interstellar space. Mission team members decided to turn off the two probes' cameras to save precious power during the long journey (and because they probably wouldn't have many chances to photograph interesting things out beyond Neptune anyway).

But Voyager 1 turned around to take one last look at home before closing its eyes. And not just its home planet — its home system. The probe took a "family portrait" series of 60 photos, capturing the sun, Venus, Jupiter, Saturn, Uranus and Neptune in addition to Earth. (Mercury was too close to the sun to be imaged, and sunlight bouncing around in the camera blocked Mars out.)

The Pale Blue Dot was the brainchild of famed astronomer, science communicator and Voyager imaging team member Carl Sagan , who first proposed snapping Earth with Voyager cameras in 1981 . And Sagan helped popularize the image and its message after the fact, writing a book called "Pale Blue Dot: A Vision of the Human Future in Space" (Random House, 1994). 

Earth was one of the last things Voyager 1 saw. The probe took the Pale Blue Dot photo at 0448 GMT on Feb. 14, 1990, just 34 minutes before its cameras were shut off forever. (The very last photos Voyager 1 took, however, were of the sun, Hansen said.)

All of the image data didn't come down to Earth until May 1, 1990, NASA officials wrote in a Pale Blue Dot explainer . Hansen couldn't wait to see our planet through Voyager 1's eyes — and, when she finally got the chance, doing so proved a bit more difficult than she had expected.

"It was actually kind of terrifying, because I didn't see it at first," she said. "Because of that beam of scattered light, it didn't pop out at me immediately. And then I was so afraid that we had missed it, or screwed up the exposure or something. So, it was such a relief when I spotted it."

That beam of scattered light may have briefly stopped Hansen's heart, but it adds a certain poetic flair to the Pale Blue Dot photo. It's almost as if the cosmos threw a spotlight onto our precious little world for a moment, to help us make it out in the abyss.

Still exploring

Both Voyagers kept flying long after February 1990. They cruised through the outer solar system and eventually popped free of the sun's sphere of influence into interstellar space.

Voyager 1 accomplished this unprecedented feat in 2012 , and its twin followed suit six years later. And both probes are still going strong. They should have enough power left to continue gathering data about their exotic surroundings through 2024 or so, mission team members have said.

The Voyager program has accomplished amazing things, shedding considerable light on the giant planets and the dark realms far beyond them. (Voyager 2, for example, is still the only spacecraft ever to get up-close looks at Uranus or Neptune.) And the Pale Blue Dot is a unique part of this diverse and layered legacy.

"The Earth picture reaches to our hearts, I would say, and all the rest goes in our heads," Hansen said.

NASA's Voyager 1 resumes sending engineering updates to Earth

For the first time since November, NASA's Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).

Voyager 1 stopped sending readable science and engineering data back to Earth on Nov. 14, 2023, even though mission controllers could tell the spacecraft was still receiving their commands and otherwise operating normally. In March, the Voyager engineering team at NASA's Jet Propulsion Laboratory in Southern California confirmed that the issue was tied to one of the spacecraft's three onboard computers, called the flight data subsystem (FDS). The FDS is responsible for packaging the science and engineering data before it's sent to Earth.

The team discovered that a single chip responsible for storing a portion of the FDS memory—including some of the FDS computer's software code—isn't working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety.

So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS. 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. Any references to the location of that code in other parts of the FDS memory needed to be updated as well.

The team started by singling out the code responsible for packaging the spacecraft's engineering data. They sent it to its new location in the FDS memory on April 18. A radio signal takes about 22.5 hours to reach Voyager 1, which is over 15 billion miles (24 billion kilometers) from Earth, and another 22.5 hours for a signal to come back to Earth. When the mission flight team heard back from the spacecraft on April 20, they saw that the modification had worked: For the first time in five months, they were able to check the health and status of the spacecraft.

During the coming weeks, the team will relocate and adjust the other affected portions of the FDS software. These include the portions that will start returning science data.

Voyager 2 continues to operate normally. Launched over 46 years ago, the twin Voyager spacecraft are the longest-running and most distant spacecraft in history. Before the start of their interstellar exploration, both probes flew by Saturn and Jupiter, and Voyager 2 flew by Uranus and Neptune.

Voyager 1: NASA's longest-running spacecraft back in touch with Earth after five months of silence

The Voyager probes are in interstellar space but Voyager 1 stopped sending back usable information in November. After months of work, NASA scientists have now heard back from the spacecraft.

By Mickey Carroll, science and technology reporter

Tuesday 23 April 2024 11:45, UK

NASA's longest-running spacecraft Voyager 1 is sending information back to Earth again for the first time since November.

Scientists have managed to fix a problem on the probe, which was launched 46 years ago, after five months of silence.

On 14 November last year, Voyager 1 stopped sending usable data back to Earth, even though scientists could tell it was still receiving their commands and working well otherwise.

Hi, it's me. - V1 https://t.co/jgGFBfxIOe — NASA Voyager (@NASAVoyager) April 22, 2024

It was first launched alongside its twin, Voyager 2. The pair are the only spacecraft to ever fly in interstellar space , which is the space between stars.

The Voyager probes send back never-seen-before information about our galaxy. Since they blasted off in 1977, they have revealed details in Saturn's rings, provided the first in-depth images of the rings of Uranus and Neptune and discovered the rings of Jupiter.

Although their cameras are switched off to conserve power and memory, they are still sending back information that would be impossible to get anywhere else.

With all this data stuck onboard and the spacecraft more than 15 billion miles from Earth, NASA scientists needed to fix the problem remotely.

Engineers have confirmed that corrupted memory aboard my twin #Voyager1 has been causing it to send unreadable data to Earth.

Within the computer, a single chip containing some of the computer's software code had stopped working. Without that code, the data was unusable.

The engineers couldn't pop over and fix it. Instead, on 18 April, they remotely split the code across different parts of the computer.

Then they had to wait to see if their fix had worked.

It takes around 22-and-a-half hours for a radio signal to reach Voyager 1 and another 22-and-a-half hours for a response to come back.

On 20 April, the team got good news. For the first time in five months, they were in contact with Voyager 1 again and could check the health and status of the spacecraft.

Now, they'll adjust the rest of the computer so it can begin sending back more data.

NASA's Voyager 1 sending readable data back to Earth for 1st time in 5 months

The problem stemmed from a corrupted chip in one of the spacecraft's computers.

After more than five months without contact, NASA has finally reconnected with Voyager 1, the farthest spacecraft from Earth.

NASA's Jet Propulsion Lab (JPL) said Voyager 1 had not been sending readable data back to Earth since Nov. 14, 2023, despite the spacecraft still receiving mission controller commands.

In December 2023, the JPL announced the problem was with one of Voyager 1's onboard computers called the flight data subsystem (FDS). Engineers attempted to restart the computer, but the problem persisted, NASA said.

However, the JPL announced this week that Voyager 1 had resumed sending engineering updates to Earth.

Engineers pinpointed the problem earlier this month, NASA said: A chip responsible for storing part of the computer's memory had become corrupted, making the data unreadable. The team was unable to repair the chip and decided the affected code needed to be stored elsewhere in the FDS memory, but no single location was large enough to do so, the JPL said in a release Monday.

The team "devised a plan to divide the affected code into sections and store those sections in different places in the FDS," the release read. "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."

The code that packages Voyager 1's engineering data was the first to be sent to its new location on April 18. The JPL said it takes 22.5 hours for a radio signal to reach Voyager 1 and another 22.5 hours for the signal to come back to Earth. When the team heard from Voyager 1 on April 20, they knew the fix was a success, the JPL said.

"Hi, it's me. - V1," the X account for Voyager 1 posted on Monday afternoon.

Over the next few weeks, more portions of the FDS software will be relocated and the team will work to enable the spacecraft to begin returning science data again, the JPL said.

Voyager 1 was launched in September 1977 under the Voyager program to study the farther planets of the solar system and interstellar space. Voyager 1 entered interstellar space in 2012 becoming the first man-made object to exit the solar system.

Meanwhile, its twin spacecraft, Voyager 2, continues to "operate normally," according to the JPL. It reached interstellar space in 2018 and is the second-farthest spacecraft from Earth.

Contact restored with NASA’s Voyager 1 space probe

Contact restored.

That was the message relieved NASA officials shared after the agency regained full contact with the Voyager 1 space probe, the most distant human-made object in the universe, scientists have announced.

For the first time since November, the spacecraft is returning usable data about the health and status of its onboard engineering systems, NASA said in a news release Monday.

The 46-year-old pioneering probe, now 15.1 billion miles from Earth, has continually defied expectations for its life span as it ventures farther into the  uncharted territory of the cosmos .

Computer experts to the rescue

It wasn't as easy as hitting Control-Alt-Delete, but top experts at NASA and CalTech were able to fix the balky, ancient computer on board the probe that was causing the communication breakdown – at least for now.

A computer problem aboard Voyager 1 on Nov. 14, 2023, corrupted the stream of science and engineering data the craft sent to Earth,  making it unreadable .

Although the radio signal from the spacecraft had never ceased its connection to ground control operators on Earth, that signal had not carried any usable data since November, NASA said. After some serious sleuthing to fix the onboard computer, that changed on April 20, when NASA finally received usable data.

In interstellar space

The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between the stars).

Voyager 2 continues to operate normally, NASA reports. Launched  more than 46 years ago , the twin spacecraft are standouts on two fronts: they've operated the longest and traveled the farthest of any spacecraft ever.

Before the start of their interstellar exploration, both probes flew by Saturn and Jupiter, and Voyager 2 flew by Uranus and Neptune.

More: NASA gave Voyager 1 a 'poke' amid communication woes. Here's why the response was encouraging.

They were  designed to last five years but have become the longest-operating spacecraft in history. Both carry  gold-plated copper discs  containing sounds and images from Earth, content that was chosen by a team headed by celebrity astronomer  Carl Sagan .

For perspective, it was the summer of 1977 when the Voyager probes left Earth. "Star Wars" was No. 1 at the box office, Jimmy Carter was in the first year of his presidency, and Elvis Presley had just died.

NASA’s Voyager 1 Resumes Sending Engineering Updates to Earth

NASA’s Voyager 1 spacecraft is depicted in this artist’s concept traveling through interstellar space, or the space between stars, which it entered in 2012.

After some inventive sleuthing, the mission team can — for the first time in five months — check the health and status of the most distant human-made object in existence.

For the first time since November , NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).

Voyager 1 stopped sending readable science and engineering data back to Earth on Nov. 14, 2023, even though mission controllers could tell the spacecraft was still receiving their commands and otherwise operating normally. In March, the Voyager engineering team at NASA’s Jet Propulsion Laboratory in Southern California confirmed that the issue was tied to one of the spacecraft’s three onboard computers, called the flight data subsystem (FDS). The FDS is responsible for packaging the science and engineering data before it’s sent to Earth.

After receiving data about the health and status of Voyager 1 for the first time in five months, members of the Voyager flight team celebrate in a conference room at NASA’s Jet Propulsion Laboratory on April 20.

The team discovered that a single chip responsible for storing a portion of the FDS memory — including some of the FDS computer’s software code — isn’t working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety.

So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS. 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. Any references to the location of that code in other parts of the FDS memory needed to be updated as well.

The team started by singling out the code responsible for packaging the spacecraft’s engineering data. They sent it to its new location in the FDS memory on April 18. A radio signal takes about 22 ½ hours to reach Voyager 1, which is over 15 billion miles (24 billion kilometers) from Earth, and another 22 ½ hours for a signal to come back to Earth. When the mission flight team heard back from the spacecraft on April 20, they saw that the modification worked: For the first time in five months, they have been able to check the health and status of the spacecraft.

During the coming weeks, the team will relocate and adjust the other affected portions of the FDS software. These include the portions that will start returning science data.

Voyager 2 continues to operate normally. Launched over 46 years ago , the twin Voyager spacecraft are the longest-running and most distant spacecraft in history. Before the start of their interstellar exploration, both probes flew by Saturn and Jupiter, and Voyager 2 flew by Uranus and Neptune.

NASA’s Voyager 1 spacecraft resumes sending data to Earth from interstellar space after 5-month outage

Voyager 1 and 2 launched in 1977 and are nasa’s oldest and most distant robotic space travelers. an issue with voyager 1’s code that began in november meant the spacecraft was unable to send back data from interstellar space. after some creative engineering to find a solution, voyager teams got the first usable data from the spacecraft on april 20..

Cheers and applause erupted this weekend when NASA’ s Voyager 1 spacecraft sent back the first usable data from interstellar space after a five-month communication gap. 

Engineers with Voyager's flight team at NASA’s Jet Propulsion Laboratory in Pasadena, California , have been troubleshooting an issue since November , when the spacecraft, more than 15.1 billion miles from Earth, began sending back nonsense computer code.

On Saturday, after 45 hours of waiting to find out if their plan to send the problem code elsewhere on the spacecraft’s computer would work, the team got its response. 

NASA ENGINEERS HAVE RENEWED HOPE TO FIX HOBBLED VOYAGER 1 AFTER INTERSTELLAR SPACE DATA OUTAGE

"For the first time since November, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems," NASA JPL said in a blog. "The next step is to enable the spacecraft to begin returning science data again."

Earlier this year, NASA engineers honed in on one of three computers on the spacecraft, known as the Flight Data System (FDS), as the cause behind the communication problem.

"Its role is to basically collect all of the data from the science instruments and the spacecraft, package them all neatly up and send them back to the Earth," Voyager Program scientist Linda Spilker told FOX Weather in mid-March. 

Eventually, the team discovered that the problem was a single chip responsible for storing part of the computer’s memory, including some of its software code. 

According to NASA, the team decided to place the problem code elsewhere in the computer’s memory. However, no single location has enough space to hold the code section, so the code was divided into sections and sent to different places on the FDS.

On April 18, the team sent the first section of code responsible for packaging the spacecraft’s engineering data. It takes 22.5 hours to send a radio signal with the repair to Voyager 1 and another 22.5 hours to receive a signal back to Earth.

HOW TO WATCH FOX WEATHER

This isn’t the first scare for either of NASA's twin interstellar spacecraft, which started as a 5-year mission and has now been operating for 46 years.

Another issue with garbled data for Voyager 1 in 2022 was fixed over several months. In 1981, the team experienced a similar communication issue to the current problem.

Voyager 2 is currently operating normally more than 12.6 billion miles from Earth. Last year, an incorrect command sent Voyager 2 pointing away from Earth , preventing it from sending back data. Teams were able to send a patch and reorient the spacecraft. 

In the coming weeks, more commands will be sent to relocate Voyager 1's problem code and adjust the FDS software. Eventually, the spacecraft will begin returning science data.
