Engineers Pinpoint Cause of Voyager 1 Issue, Are Working on Solution

Engineers have confirmed that a small portion of corrupted memory in one of the computers aboard NASA’s Voyager 1 has been causing the spacecraft to send unreadable science and engineering data to Earth since last November. Called the flight data subsystem (FDS), the computer is responsible for packaging the probe’s science and engineering data before the telemetry modulation unit (TMU) and radio transmitter send the data to Earth.

In early March , the team issued a “poke” command to prompt the spacecraft to send back a readout of the FDS memory, which includes the computer’s software code as well as variables (values used in the code that can change based on commands or the spacecraft’s status). Using the readout, the team has confirmed that about 3% of the FDS memory has been corrupted, preventing the computer from carrying out normal operations.

The team suspects that a single chip responsible for storing part of the affected portion of the FDS memory isn’t working. Engineers can’t determine with certainty what caused the issue. Two possibilities are that the chip could have been hit by an energetic particle from space or that it simply may have worn out after 46 years.

Although it may take weeks or months, engineers are optimistic they can find a way for the FDS to operate normally without the unusable memory hardware, which would enable Voyager 1 to begin returning science and engineering data again.

Launched in 1977 , the twin Voyager spacecraft flew by Saturn and Jupiter, and Voyager 2 flew by Uranus and Neptune. They are both exploring interstellar space, outside the bubble of particles and magnetic fields created by the Sun, called the heliosphere. Voyager 2 continues to operate normally.

Engineers solve data glitch on nasa’s voyager 1, jet propulsion laboratory.

A critical system aboard the probe was sending garbled data about its status. Engineers have fixed the issue but are still seeking the root cause.

Engineers have repaired an issue affecting data from NASA’s Voyager 1 spacecraft. Earlier this year , the probe’s attitude articulation and control system (AACS), which keeps Voyager 1’s antenna pointed at Earth, began sending garbled information about its health and activities to mission controllers, despite operating normally. The rest of the probe also appeared healthy as it continued to gather and return science data.

The team has since located the source of the garbled information: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.

Suzanne Dodd, Voyager’s project manager, said that when they suspected this was the issue, they opted to try a low-risk solution: commanding the AACS to resume sending the data to the right computer.

Engineers don’t yet know why the AACS started routing telemetry data to the incorrect computer, but it likely received a faulty command generated by another onboard computer. If that’s the case, it would indicate there is an issue somewhere else on the spacecraft. The team will continue to search for that underlying issue, but they don’t think it is a threat to the long-term health of Voyager 1.  

“We’re happy to have the telemetry back,” said Dodd. “We’ll do a full memory readout of the AACS and look at everything it’s been doing. That will help us try to diagnose the problem that caused the telemetry issue in the first place. So we’re cautiously optimistic, but we still have more investigating to do.”

Voyager 1 and Voyager 2 have been exploring our solar system for 45 years . Both probes are now in interstellar space , the region outside the heliopause, or the bubble of energetic particles and magnetic fields from the Sun.

While the spacecraft continues to return science data and otherwise operate as normal, the mission team is searching for the source of a system data issue.

The engineering team with NASA’s Voyager 1 spacecraft is trying to solve a mystery: The interstellar explorer is operating normally, receiving and executing commands from Earth, along with gathering and returning science data. But readouts from the probe’s attitude articulation and control system (AACS) don’t reflect what’s actually happening onboard.

The AACS controls the 45-year-old spacecraft’s orientation. Among other tasks, it keeps Voyager 1’s high-gain antenna pointed precisely at Earth, enabling it to send data home. All signs suggest the AACS is still working, but the telemetry data it’s returning is invalid. For instance, the data may appear to be randomly generated, or does not reflect any possible state the AACS could be in.

The issue hasn’t triggered any onboard fault protection systems, which are designed to put the spacecraft into “safe mode” – a state where only essential operations are carried out, giving engineers time to diagnose an issue. Voyager 1’s signal hasn’t weakened, either, which suggests the high-gain antenna remains in its prescribed orientation with Earth.

The team will continue to monitor the signal closely as they continue to determine whether the invalid data is coming directly from the AACS or another system involved in producing and sending telemetry data. Until the nature of the issue is better understood, the team cannot anticipate whether this might affect how long the spacecraft can collect and transmit science data.

Voyager 1 is currently 14.5 billion miles (23.3 billion kilometers) from Earth, and it takes light 20 hours and 33 minutes to travel that difference. That means it takes roughly two days to send a message to Voyager 1 and get a response – a delay the mission team is well accustomed to.

“A mystery like this is sort of par for the course at this stage of the Voyager mission,” said Suzanne Dodd, project manager for Voyager 1 and 2 at NASA’s Jet Propulsion Laboratory in Southern California. “The spacecraft are both almost 45 years old, which is far beyond what the mission planners anticipated. We’re also in interstellar space – a high-radiation environment that no spacecraft have flown in before. So there are some big challenges for the engineering team. But I think if there’s a way to solve this issue with the AACS, our team will find it.”

It’s possible the team may not find the source of the anomaly and will instead adapt to it, Dodd said. If they do find the source, they may be able to solve the issue through software changes or potentially by using one of the spacecraft’s redundant hardware systems.

It wouldn’t be the first time the Voyager team has relied on backup hardware: In 2017, Voyager 1’s primary thrusters showed signs of degradation, so engineers switched to another set of thrusters that had originally been used during the spacecraft’s planetary encounters . Those thrusters worked, despite having been unused for 37 years.

Voyager 1’s twin, Voyager 2 (currently 12.1 billion miles, or 19.5 billion kilometers, from Earth), continues to operate normally.

Launched in 1977, both Voyagers have operated far longer than mission planners expected, and are the only spacecraft to collect data in interstellar space. The information they provide from this region has helped drive a deeper understanding of the heliosphere, the diffuse barrier the Sun creates around the planets in our solar system.

Each spacecraft produces about 4 fewer watts of electrical power a year, limiting the number of systems the craft can run. The mission engineering team has switched off various subsystems and heaters in order to reserve power for science instruments and critical systems. No science instruments have been turned off yet as a result of the diminishing power, and the Voyager team is working to keep the two spacecraft operating and returning unique science beyond 2025.

While the engineers continue to work at solving the mystery that Voyager 1 has presented them, the mission’s scientists will continue to make the most of the data coming down from the spacecraft’s unique vantage point.

Some hope —

Finally, engineers have a clue that could help them save voyager 1, a new signal from humanity's most distant spacecraft could be the key to restoring it..

Stephen Clark - Mar 15, 2024 11:23 pm UTC

It's been four months since NASA's Voyager 1 spacecraft sent an intelligible signal back to Earth, and the problem has puzzled engineers tasked with supervising the probe exploring interstellar space.

But there's a renewed optimism among the Voyager ground team based at NASA's Jet Propulsion Laboratory in California. On March 1, engineers sent a command up to Voyager 1—more than 15 billion miles (24 billion kilometers) away from Earth—to "gently prompt" one of the spacecraft's computers to try different sequences in its software package. This was the latest step in NASA's long-distance troubleshooting to try to isolate the cause of the problem preventing Voyager 1 from transmitting coherent telemetry data.

Cracking the case

Officials suspect a piece of corrupted memory inside the Flight Data Subsystem (FDS), one of three main computers on the spacecraft, is the most likely culprit for the interruption in normal communication. Because Voyager 1 is so far away, it takes about 45 hours for engineers on the ground to know how the spacecraft reacted to their commands—the one-way light travel time is about 22.5 hours.

The FDS collects science and engineering data from the spacecraft's sensors, then combines the information into a single data package, which goes through a separate component called the Telemetry Modulation Unit to beam it back to Earth through Voyager's high-gain antenna.

Engineers are almost entirely certain the problem is in the FDS computer. The communications systems onboard Voyager 1 appear to be functioning normally, and the spacecraft is sending a steady radio tone back to Earth, but there's no usable data contained in the signal. This means engineers know Voyager 1 is alive, but they have no insight into what part of the FDS memory is causing the problem.

But Voyager 1 responded to the March 1 troubleshooting command with something different from what engineers have seen since this issue first appeared on November 14.

"The new signal was still not in the format used by Voyager 1 when the FDS is working properly, so the team wasn’t initially sure what to make of it," NASA said in an update Wednesday. "But an engineer with the agency’s Deep Space Network, which operates the radio antennas that communicate with both Voyagers and other spacecraft traveling to the Moon and beyond, was able to decode the new signal and found that it contains a readout of the entire FDS memory."

Now, engineers are meticulously comparing each bit of code from the FDS memory readout to the memory readout Voyager 1 sent back to Earth before the issue arose in November. This, they hope, will allow them to find the root of the problem. But it will probably take weeks or months for the Voyager team to take the next step. They don't want to cause more harm.

"Using that information to devise a potential solution and attempt to put it into action will take time," NASA said.

This is perhaps the most serious ailment the spacecraft has encountered since its launch in 1977. Voyager 1 flew by Jupiter and Saturn before getting a kick from Saturn's gravity to speed into the outer solar system. In 2012, Voyager 1 entered interstellar space when it crossed the heliopause, where the solar wind, the stream of particles emanating from the Sun, push against a so-called galactic wind, the particles that populate the void between the stars.

Engineers have kept Voyager 1 and its twin, Voyager 2, alive for more than 46 years , overcoming technical problems that have doomed other space missions. Both probes face waning power from their nuclear batteries, and there are concerns about their thrusters aging and fuel lines becoming clogged, among other things. But each time there is a problem, ground teams have come up with a trick to keep the Voyagers going, often referencing binders of fraying blueprints and engineering documents from the spacecraft's design and construction nearly 50 years ago.

Suzanne Dodd, NASA's project manager for Voyager 1 and its twin, Voyager 2, recently told Ars that engineers would need to pull off their "biggest miracle" to restore Voyager 1 to normal operations. Now, Voyager 1's voice from the sky has provided engineers with a clue that could help them realize this miracle.

We finally know why NASA's Voyager 1 spacecraft stopped communicating — scientists are working on a fix

The first spacecraft to explore beyond the solar system started spouting gibberish late last year. Now, NASA knows why.

NASA engineers have discovered the cause of a communications breakdown between Earth and the interstellar explorer Voyager 1. It would appear that a small portion of corrupted memory exists in one of the spacecraft's computers. 

The glitch caused Voyager 1 to send unreadable data back to Earth, and is found in the NASA spacecraft's flight data subsystem (FDS). That's the system responsible for packaging the probe's science and engineering data before the telemetry modulation unit (TMU) and radio transmitter send it back to mission control. 

The source of the issue began to reveal itself when Voyager 1 operators sent the spacecraft a "poke" on March 3, 2024. This was intended to prompt FDS to send a full memory readout back to Earth.

The readout confirmed to the NASA team that about 3% of the FDS memory had been corrupted, and that this was preventing the computer from carrying out its normal operations.

Launched in 1977, Voyager 1 became the first human-made object to leave the solar system and enter interstellar space in 2012. Voyager 2 followed its spacecraft sibling out of the solar system in 2018, and is still operational and communicating well with  Earth.

After 11 years of interstellar exploration, in Nov. 2023, Voyager 1's binary code — the computer language it uses to communicate with Earth — stopped making sense. Its 0's and 1's didn't mean anything anymore.

"Effectively, the call between the spacecraft and the Earth was still connected, but Voyager's 'voice' was replaced with a monotonous dial tone," Voyager 1's engineering team previously  told Space.com .

The team strongly suspects this glitch is the result of a single chip that's responsible for storing part of the affected portion of the FDS memory ceasing to work.

Currently, however, NASA can’t say for sure what exactly caused that particular issue. The chip could have been struck by a high-speed energetic particle from space or, after 46 years serving Voyager 1, it may simply have worn out.

—  NASA Voyager 2 spacecraft extends its interstellar science mission for 3 more years

Voyager 1 currently sits around 15 billion miles (24 billion kilometers) from Earth, which means it takes 22.5 hours to receive a radio signal from it — and another 22.5 hours for the spacecraft to receive a response via the Deep Space Network's antennas. Solving this communication issue is thus no mean feat.

Yet, NASA scientists and engineers are optimistic they can find a way to help FDS operate normally, even without the unusable memory hardware.

Solving this issue could take weeks or even months, according to NASA — but if it is resolved, Voyager 1 should be able to resume returning science data about what lies outside the solar system.

When Voyager 1 launched in 1977, scientists hoped it could do what it was built to do and take up-close images of Jupiter and Saturn. It did that — and much more.

Voyager 1 discovered active volcanoes, moons and planetary rings, proving along the way that Earth and all of humanity could be squished into a single pixel in a photograph, a “ pale blue dot, ” as the astronomer Carl Sagan called it. It stretched a four-year mission into the present day, embarking on the deepest journey ever into space.

Now, it may have bid its final farewell to that faraway dot.

Voyager 1 , the farthest man-made object in space, hasn’t sent coherent data to Earth since November. NASA has been trying to diagnose what the Voyager mission’s project manager, Suzanne Dodd, called the “most serious issue” the robotic probe has faced since she took the job in 2010.

The spacecraft encountered a glitch in one of its computers that has eliminated its ability to send engineering and science data back to Earth.

The loss of Voyager 1 would cap decades of scientific breakthroughs and signal the beginning of the end for a mission that has given shape to humanity’s most distant ambition and inspired generations to look to the skies.

“Scientifically, it’s a big loss,” Ms. Dodd said. “I think — emotionally — it’s maybe even a bigger loss.”

Voyager 1 is one half of the Voyager mission. It has a twin spacecraft, Voyager 2.

Launched in 1977, they were primarily built for a four-year trip to Jupiter and Saturn , expanding on earlier flybys by the Pioneer 10 and 11 probes.

The Voyager mission capitalized on a rare alignment of the outer planets — once every 175 years — allowing the probes to visit all four.

Using the gravity of each planet, the Voyager spacecraft could swing onto the next, according to NASA .

The mission to Jupiter and Saturn was a success.

The 1980s flybys yielded several new discoveries, including new insights about the so-called great red spot on Jupiter, the rings around Saturn and the many moons of each planet.

Voyager 2 also explored Uranus and Neptune , becoming in 1989 the only spacecraft to explore all four outer planets.

Voyager 1, meanwhile, had set a course for deep space, using its camera to photograph the planets it was leaving behind along the way. Voyager 2 would later begin its own trek into deep space.

“Anybody who is interested in space is interested in the things Voyager discovered about the outer planets and their moons,” said Kate Howells, the public education specialist at the Planetary Society, an organization co-founded by Dr. Sagan to promote space exploration.

“But I think the pale blue dot was one of those things that was sort of more poetic and touching,” she added.

On Valentine’s Day 1990, Voyager 1, darting 3.7 billion miles away from the sun toward the outer reaches of the solar system, turned around and snapped a photo of Earth that Dr. Sagan and others understood to be a humbling self-portrait of humanity.

“It’s known the world over, and it does connect humanity to the stars,” Ms. Dodd said of the mission.

She added: “I’ve had many, many many people come up to me and say: ‘Wow, I love Voyager. It’s what got me excited about space. It’s what got me thinking about our place here on Earth and what that means.’”

Ms. Howells, 35, counts herself among those people.

About 10 years ago, to celebrate the beginning of her space career, Ms. Howells spent her first paycheck from the Planetary Society to get a Voyager tattoo.

Though spacecraft “all kind of look the same,” she said, more people recognize the tattoo than she anticipated.

“I think that speaks to how famous Voyager is,” she said.

The Voyagers made their mark on popular culture , inspiring a highly intelligent “Voyager 6” in “Star Trek: The Motion Picture” and references on “The X Files” and “The West Wing.”

Even as more advanced probes were launched from Earth, Voyager 1 continued to reliably enrich our understanding of space.

In 2012, it became the first man-made object to exit the heliosphere, the space around the solar system directly influenced by the sun. There is a technical debate among scientists around whether Voyager 1 has actually left the solar system, but, nonetheless, it became interstellar — traversing the space between stars.

That charted a new path for heliophysics, which looks at how the sun influences the space around it. In 2018, Voyager 2 followed its twin between the stars.

Before Voyager 1, scientific data on the sun’s gases and material came only from within the heliosphere’s confines, according to Dr. Jamie Rankin, Voyager’s deputy project scientist.

“And so now we can for the first time kind of connect the inside-out view from the outside-in,” Dr. Rankin said, “That’s a big part of it,” she added. “But the other half is simply that a lot of this material can’t be measured any other way than sending a spacecraft out there.”

Voyager 1 and 2 are the only such spacecraft. Before it went offline, Voyager 1 had been studying an anomalous disturbance in the magnetic field and plasma particles in interstellar space.

“Nothing else is getting launched to go out there,” Ms. Dodd said. “So that’s why we’re spending the time and being careful about trying to recover this spacecraft — because the science is so valuable.”

But recovery means getting under the hood of an aging spacecraft more than 15 billion miles away, equipped with the technology of yesteryear. It takes 45 hours to exchange information with the craft.

It has been repeated over the years that a smartphone has hundreds of thousands of times Voyager 1’s memory — and that the radio transmitter emits as many watts as a refrigerator lightbulb.

“There was one analogy given that is it’s like trying to figure out where your cursor is on your laptop screen when your laptop screen doesn’t work,” Ms. Dodd said.

Her team is still holding out hope, she said, especially as the tantalizing 50th launch anniversary in 2027 approaches. Voyager 1 has survived glitches before, though none as serious.

Voyager 2 is still operational, but aging. It has faced its own technical difficulties too.

NASA had already estimated that the nuclear-powered generators of both spacecrafts would likely die around 2025.

Even if the Voyager interstellar mission is near its end, the voyage still has far to go.

Voyager 1 and its twin, each 40,000 years away from the next closest star, will arguably remain on an indefinite mission.

“If Voyager should sometime in its distant future encounter beings from some other civilization in space, it bears a message,” Dr. Sagan said in a 1980 interview .

Each spacecraft carries a gold-plated phonograph record loaded with an array of sound recordings and images representing humanity’s richness, its diverse cultures and life on Earth.

“A gift across the cosmic ocean from one island of civilization to another,” Dr. Sagan said.

NASA tries to jog Voyager 1's memory from 15 billion miles away

Since you can't get a soldering iron out there, the fix will be in software.

Engineers at NASA have pinpointed some corrupted memory as the cause of Voyager 1's troubles and are working on a remote fix to deal with the hardware problem.…

The veteran probe began sending unreadable data back to Earth in late 2023, and engineers have tried to understand the nature of the issue. Last month, they sent a command – a "poke" to the spacecraft's Flight Data System (FDS) – and the resulting data stream contained a complete memory dump from the computer.

The team was able to use this readout, which contained the computer's code and variables, to ascertain that approximately 3 percent of the FDS memory had been corrupted. That corruption is preventing normal operation of the FDS, which is responsible for packaging the probe's engineering and science data before it gets passed to the Telemetry Modulation Unit (TMU), the radio transmitter and is sent back to Earth.

The Voyager team reckons that a single chip responsible for the corrupted portion of memory is at fault, although they can only make an informed guess with regard to what has happened.

Two leading theories are that the chip has simply worn out having spent 46 years in space, or that an energetic particle might have damaged it.

As Voyager 1 is well out of the reach of any physical intervention, the issue will need to be addressed in software.

According to NASA: "Although it may take weeks or months, engineers are optimistic they can find a way for the FDS to operate normally without the unusable memory hardware, which would enable Voyager 1 to begin returning science and engineering data again."

Computer problems caused by cosmic rays and energetic particles have long challenged spacecraft designers. Some might merely result in a bit flip, while others can leave satellites inoperable or damaged.

Voyager 2 suffered a bit flip in 2010, which caused problems with science data transmitted from the spacecraft and was traced to the FDS. A computer reset dealt with the problem.

This time, however, the hardware appears to have become inoperative, requiring engineers to devise something more complicated than a simple turn-it-off-and-on-again solution. ®

Engineers investigating nasa's voyager 1 telemetry data.

While the spacecraft continues to return science data and otherwise operate as normal, the mission team is searching for the source of a system data issue.

The AACS controls the 45-year-old spacecraft's orientation. Among other tasks, it keeps Voyager 1's high-gain antenna pointed precisely at Earth, enabling it to send data home. All signs suggest the AACS is still working, but the telemetry data it's returning is invalid. For instance, the data may appear to be randomly generated, or does not reflect any possible state the AACS could be in.

The issue hasn't triggered any onboard fault protection systems, which are designed to put the spacecraft into "safe mode" – a state where only essential operations are carried out, giving engineers time to diagnose an issue. Voyager 1's signal hasn't weakened, either, which suggests the high-gain antenna remains in its prescribed orientation with Earth.

The team will continue to monitor the signal closely as they continue to determine whether the invalid data is coming directly from the AACS or another system involved in producing and sending telemetry data. Until the nature of the issue is better understood, the team cannot anticipate whether this might affect how long the spacecraft can collect and transmit science data.

Voyager 1 is currently 14.5 billion miles (23.3 billion kilometers) from Earth, and it takes light 20 hours and 33 minutes to travel that difference. That means it takes roughly two days to send a message to Voyager 1 and get a response – a delay the mission team is well accustomed to.

"A mystery like this is sort of par for the course at this stage of the Voyager mission," said Suzanne Dodd, project manager for Voyager 1 and 2 at NASA's Jet Propulsion Laboratory in Southern California. "The spacecraft are both almost 45 years old, which is far beyond what the mission planners anticipated. We're also in interstellar space – a high-radiation environment that no spacecraft have flown in before. So there are some big challenges for the engineering team. But I think if there's a way to solve this issue with the AACS, our team will find it."

It's possible the team may not find the source of the anomaly and will instead adapt to it, Dodd said. If they do find the source, they may be able to solve the issue through software changes or potentially by using one of the spacecraft's redundant hardware systems.

It wouldn't be the first time the Voyager team has relied on backup hardware: In 2017, Voyager 1's primary thrusters showed signs of degradation, so engineers switched to another set of thrusters that had originally been used during the spacecraft's planetary encounters . Those thrusters worked, despite having been unused for 37 years.

Voyager 1's twin, Voyager 2 (currently 12.1 billion miles, or 19.5 billion kilometers, from Earth), continues to operate normally.

Launched in 1977, both Voyagers have operated far longer than mission planners expected, and are the only spacecraft to collect data in interstellar space. The information they provide from this region has helped drive a deeper understanding of the heliosphere, the diffuse barrier the Sun creates around the planets in our solar system.

Each spacecraft produces about 4 fewer watts of electrical power a year, limiting the number of systems the craft can run. The mission engineering team has switched off various subsystems and heaters in order to reserve power for science instruments and critical systems. No science instruments have been turned off yet as a result of the diminishing power, and the Voyager team is working to keep the two spacecraft operating and returning unique science beyond 2025.

While the engineers continue to work at solving the mystery that Voyager 1 has presented them, the mission's scientists will continue to make the most of the data coming down from the spacecraft's unique vantage point.

More About the Mission

The Voyager spacecraft were built by JPL, which continues to operate both. JPL is a division of Caltech in Pasadena. The Voyager missions are a part of the NASA Heliophysics System Observatory, sponsored by the Heliophysics Division of the Science Mission Directorate in Washington.

Engineers Diagnosing Voyager 2 Data System -- Update

Engineers successfully reset a computer onboard Voyager 2 that caused an unexpected data pattern shift, and the spacecraft resumed sending properly formatted science data back to Earth on Sunday, May 23

Updated May 24, 2010 at 5:30 p.m. PDT

Engineers successfully reset a computer onboard Voyager 2 that caused an unexpected data pattern shift, and the spacecraft resumed sending properly formatted science data back to Earth on Sunday, May 23. Mission managers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., had been operating the spacecraft in engineering mode since May 6. They took this action as they traced the source of the pattern shift to the flip of a single bit in the flight data system computer that packages data to transmit back to Earth. In the next week, engineers will be checking the science data with Voyager team scientists to make sure instruments onboard the spacecraft are processing data correctly.

Updated May 20, 2010 at 6:00 p.m. PDT

Engineers have successfully corrected the memory on NASA's Voyager 2 spacecraft by resetting a computer bit that had flipped. Reset commands were beamed up to the spacecraft yesterday, Wed., May 19, and engineering data received today confirm that the reset was successful. The Voyager team will continue monitoring the engineering data, and if the bit remains reset, commands to switch to the science data mode will be beamed up to Voyager 2 on Sat., May 22. Receipt of science data would then resume on Sun., May 23.

Updated May 17, 2010 at 5:00 p.m. PDT

One flip of a bit in the memory of an onboard computer appears to have caused the change in the science data pattern returning from Voyager 2, engineers at NASA's Jet Propulsion Laboratory said Monday, May 17. A value in a single memory location was changed from a 0 to a 1.

On May 12, engineers received a full memory readout from the flight data system computer, which formats the data to send back to Earth. They isolated the one bit in the memory that had changed, and they recreated the effect on a computer at JPL. They found the effect agrees with data coming down from the spacecraft. They are planning to reset the bit to its normal state on Wednesday, May 19.

May 06, 2010

Engineers have shifted NASA's Voyager 2 spacecraft into a mode that transmits only spacecraft health and status data while they diagnose an unexpected change in the pattern of returning data. Preliminary engineering data received on May 1 show the spacecraft is basically healthy, and that the source of the issue is the flight data system, which is responsible for formatting the data to send back to Earth. The change in the data return pattern has prevented mission managers from decoding science data.

The first changes in the return of data packets from Voyager 2, which is near the edge of our solar system, appeared on April 22. Mission team members have been working to troubleshoot and resume the regular flow of science data. Because of a planned roll maneuver and moratorium on sending commands, engineers got their first chance to send commands to the spacecraft on April 30. It takes nearly 13 hours for signals to reach the spacecraft and nearly 13 hours for signals to come down to NASA's Deep Space Network on Earth.

Voyager 2 launched on August 20, 1977, about two weeks before its twin spacecraft, Voyager 1. The two spacecraft are the most distant human-made objects, out at the edge of the heliosphere, the bubble the sun creates around the solar system. Mission managers expect Voyager 1 to leave our solar system and enter interstellar space in the next five years or so, with Voyager 2 on track to enter interstellar space shortly afterward. Voyager 1 is in good health and performing normally.

"Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later," said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena. "It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery."

The original goals for the two Voyager spacecraft were to explore Jupiter and Saturn.

As part of a mission extension, Voyager 2 also flew by Uranus in 1986 and Neptune in 1989, taking advantage of a once-in-176-year alignment to take a grand tour of the outer planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and 450-meter-per-second (1,000-mph) winds. It also detected geysers erupting from the pinkish-hued nitrogen ice that forms the polar cap of Neptune's moon Triton. Working in concert with Voyager 1, it also helped discover actively erupting volcanoes on Jupiter's moon Io, and waves and kinks in Saturn's icy rings from the tugs of nearby moons.

Voyager 2 is about 13.8 billion kilometers, or 8.6 billion miles, from Earth. Voyager 1 is about 16.9 billion kilometers (10.5 billion miles) away from Earth.

The Voyagers were built by JPL, which continues to operate both spacecraft. Caltech manages JPL for NASA.

Engineers attempt to fix a computer glitch on Voyager 1

Voyager 1's system that sends data home is malfunctioning, preventing the computer from operating as it should.

Social Sharing

Last November, the Voyager 1 spacecraft began sending gibberish radio signals back to Earth. Engineers have now identified the problem, but trying to repair a 46-year-old device on a craft 24 billion kilometres from Earth is not easy.

Voyager 1 and its twin Voyager 2 were both launched in 1977 on a reconnaissance mission to Jupiter and Saturn. They were designed to fly past the giant planets to obtain closeup images of those distant worlds and their myriad of moons.

Both spacecraft performed beyond expectations, discovering many new moons — some covered in ice , one with active volcanoes , another with a thick atmosphere and closeup details of Saturn's rings .  

Following the Saturn encounter, Voyager 1 was flung upwards by Saturn's gravity on a trajectory northward, above the orbital plane in which most of the planets orbit the Sun, out of our solar system. NASA extended its mission and from there it went on to become the first human-made object to venture into interstellar space in 2012. 

Voyager 2, however, was aimed toward Uranus and Neptune, which were conveniently positioned in a rare alignment with Jupiter and Saturn making it the only spacecraft to visit those distant worlds.

Following the grand tour of the outer solar system, Voyager 2 was also tossed out toward interstellar space in 2018 when its mission was extended and where it continues on its journey today. 

• After a 42-year journey, Voyager 2 goes interstellar
• Voyager 1 picks up the 'hum' of interstellar space

While their primary missions were over, both spacecraft were still in good health, thanks largely to their nuclear power sources or Radioisotope Thermoelectric Generators (RTG). These containers hold small amounts of plutonium which provide heat that is turned directly into electricity with no moving parts. They have an expected lifetime of around 50 years and have kept the Voyagers' instruments running.

Now, as both spacecraft continue their journey through the space between the stars, they are showing signs of their age.

For Voyager 1, the problem seems to be in the flight data subsystem (FDS) that packages data from the scientific instruments for transmission to Earth. The scientists don't know if the faulty module was corrupted by cosmic rays or just worn out, but they say they're optimistic they may be able to work around the problem, although it will take some time.

Engineers have confirmed that corrupted memory aboard my twin <a href="https://twitter.com/hashtag/Voyager1?src=hash&amp;ref_src=twsrc%5Etfw">#Voyager1</a> has been causing it to send unreadable data to Earth. It may take months, but our team is optimistic they can find a way for the FDS to operate normally again: <a href="https://t.co/qe5iQUu4Oj">https://t.co/qe5iQUu4Oj</a> <a href="https://t.co/AGFBZFz53v">https://t.co/AGFBZFz53v</a> &mdash; @NASAVoyager

The challenge is that the computers were built in the 1970s using old code and send data very slowly by today's standards.

In addition, these computers are so deep in space, it takes 22.5 hours for a radio signal from Voyager 1 to reach Earth. That means the controllers on the ground have to wait 45 hours for each two-way communication with the spacecraft.

Given how very, very far they are from home, if something goes wrong with them, it's up to engineers on the ground to fix it by sending radio signals since reaching them for repair missions isn't possible. We're a long way from the fictional warp drive and sub-space communication that made life so easy on the Starship Enterprise of Star Trek fame. 

The twin Voyagers are now the most distant objects ever sent from Earth; a demonstration of how vast space is and how slow our spacecraft are. In 1977, I attended the launch of Voyager 2 when my hair was black and skin was smooth. This one mission with Voyager 1 and 2 has occupied a good chunk of my lifetime.

In another few years, the RTGs on both Voyagers are expected to run down to the point where the spacecraft will no longer be able to communicate with Earth. They will just continue to drift in silence among the stars of the Milky Way for billions of years. 

However, there is one item on both Voyagers that will continue to function, the Golden Record, which carries a message from Earth to anyone out there who may find the spacecraft in the future.

The chances of them being found are astronomically small, but they will become the longest running experiment in human history.

Voyager Digital Recovers 30%: Second Distribution Coming For Crypto Creditors

Zinger key points.

• Voyager Digital secures $484.35 million from FTX, 3AC, and D&O insurance.
• Uncashed Voyager checks will be cancelled after April 20, 2024.

Announcing its progress in recovering funds from various sources, bankrupt firm Voyager Digital on Wednesday announced it has secured a combined $484.35 million from FTX , Three Arrows Capital (3AC), and Directors and Officers (D&O) insurance settlements.

In a detailed status update regarding the recovery and distribution of assets to creditors following the firm’s financial collapse to the United States Bankruptcy Court for the Southern District of New York, the company stated that the bulk of the recovered funds—approximately $450 million—will come from the settlement with FTX.

This amount represents about 25% of Voyager creditors’ original claims and is expected to be disbursed in a forthcoming distribution round.

This settlement with FTX, which includes interest, is a significant step toward reimbursing creditors affected by Voyager's downfall.

In addition to the FTX settlement, Voyager has secured a claim of roughly $675 million in the ongoing Three Arrows Capital proceedings.

Of this, $20.43 million constitutes Voyager’s pro rata share of the initial distribution from Three Arrows Capital.

The plan administrator anticipates that further payments will be made over the next few years as assets continue to be liquidated and as litigation recoveries are achieved.

Furthermore, a settlement reached in the D&O insurance mediation will provide no less than $14.35 million for the benefit of Voyager creditors.

This settlement is part of the broader efforts to compensate those affected by the company’s financial mismanagement.

Challenges With Uncashed Checks And Security Concerns

The report also highlighted logistical issues, such as approximately 270,000 uncashed checks totaling $17 million.

A significant portion of these checks, around 187,000, are for amounts less than $25.

The plan administrator has set a deadline of April 20, 2024, after which all outstanding checks will be canceled and deemed unclaimed.

Additionally, Voyager continues to grapple with the aftermath of a data breach.

The investigation, assisted by specialized external professionals, is still underway to determine the source and full impact of the breach, which compromised creditor information.

Implications For The Digital Asset Industry And Upcoming Conference

These developments in Voyager Digital’s bankruptcy case are set to be a topic of discussion at Benzinga’s upcoming Future of Digital Assets conference on Nov. 19.

The conference will delve into the implications of such high-profile bankruptcies within the cryptocurrency sector, exploring both the financial and regulatory repercussions.
