About the mission

The Voyager 2 spacecraft, which has been in operation since 1977 and is the only spacecraft to have ever visited Uranus and Neptune, has made its way to interstellar space, where its twin spacecraft, Voyager 1, has resided since August 2012. During its travels through the outer solar system, Voyager 2 visited all four gas giant planets, and also discovered and photographed many of the planets' moons.

The spacecraft's flyby of Neptune in 1989 set it on a course below the elliptic plane that eventually took it to interstellar space on November 5, 2018. In 1998, engineers switched off the spacecraft's nonessential instruments to conserve power. Data from at least some of the six instruments still in operation should be received until at least 2025.

Talk about a long-distance call.

NASA said it resumed full communications with the Voyager 2 on Friday after almost two weeks of silence from the interstellar spacecraft.

The agency's Jet Propulsion Laboratory said a series of ground antennas, part of the Deep Space Network, registered a carrier signal from Voyager 2 on Tuesday. However, the signal was too faint.

A Deep Space Network facility in Australia then sent "the equivalent of an interstellar 'shout' " to the Voyager 2 telling it to turn its antenna back toward Earth. The signal was sent more than 12.3 billion miles away and it took 37 hours to get a response from the spacecraft, NASA said.

Scientists received a response at about 12:30 a.m. ET Friday. Voyager 2 is now operating normally, returning science and telemetry data, and "remains on its expected trajectory," NASA said.

NASA said Friday that it lost contact with Voyager 2 on July 21 after "a series of planned commands" inadvertently caused the craft to turn its antenna 2 degrees away from the direction of its home planet.

What might seem like a slight error had big consequences: NASA previously said it wouldn't be able to communicate with the craft until October, when the satellite would go through one of its routine repositioning steps.

"That is a long time to wait, so we'll try sending up commands several times" before October, program manager Suzanne Dodd told The Associated Press.

Even if Voyager 2 had failed to reestablish communications until fall, the engineers expected it to stay moving on its planned trajectory on the edge of the solar system.

Voyager 2 entered interstellar space in November 2018 — more than 40 years since it launched from Cape Canaveral, Fla. To this day, Voyager 2 remains one of only two human-made objects to ever operate outside the heliosphere, which NASA defines as "the protective bubble of particles and magnetic fields generated by the Sun."

Its primary mission was to study the outer solar system, and already, Voyager 2 has proved its status as a planetary pioneer . Equipped with several imaging instruments, the spacecraft is credited with documenting the discovery of 16 new moons, six new rings and Neptune's "Great Dark Spot."

Voyager 2 is also carrying some precious cargo, like a message in a bottle, should it find itself as the subject of another world's discovery: a golden record containing a variety of natural sounds, greetings in 55 languages and a 90-minute selection of music.

Last month's command mix-up foreshadows the craft's inevitable end an estimated three years from now.

"Eventually, there will not be enough electricity to power even one instrument," reads a NASA page documenting the spacecraft's travels . "Then, Voyager 2 will silently continue its eternal journey among the stars."

Meanwhile, Voyager 2's sister spacecraft, Voyager 1, is still broadcasting and transmitting data just fine from a slightly farther vantage point of 15 billion miles away.

A previous version of this article implied that Voyager 2 flew past Uranus in 2018 when, in fact, the spacecraft concluded its encounter with the planet and started heading toward Neptune in 1986. Voyager 2 entered interstellar space in November 2018.

Well, hello, Voyager 1! The venerable spacecraft is once again making sense

Members of the Voyager team celebrate at NASA's Jet Propulsion Laboratory after receiving data about the health and status of Voyager 1 for the first time in months.

NASA says it is once again able to get meaningful information back from the Voyager 1 probe, after months of troubleshooting a glitch that had this venerable spacecraft sending home messages that made no sense.

The Voyager 1 and Voyager 2 probes launched in 1977 on a mission to study Jupiter and Saturn but continued onward through the outer reaches of the solar system. In 2012, Voyager 1 became the first spacecraft to enter interstellar space, the previously unexplored region between the stars. (Its twin, traveling in a different direction, followed suit six years later.)

Voyager 1 had been faithfully sending back readings about this mysterious new environment for years — until November, when its messages suddenly became incoherent .

NASA's Voyager 1 spacecraft is talking nonsense. Its friends on Earth are worried

It was a serious problem that had longtime Voyager scientists worried that this historic space mission wouldn't be able to recover. They'd hoped to be able to get precious readings from the spacecraft for at least a few more years, until its power ran out and its very last science instrument quit working.

For the last five months, a small team at NASA's Jet Propulsion Laboratory in California has been working to fix it. The team finally pinpointed the problem to a memory chip and figured out how to restore some essential software code.

"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," NASA stated in an update.

The usable data being returned so far concerns the workings of the spacecraft's engineering systems. In the coming weeks, the team will do more of this software repair work so that Voyager 1 will also be able to send science data, letting researchers once again see what the probe encounters as it journeys through interstellar space.

Most distant spacecraft from Earth sends data to NASA for first time in 5 months

By Kerry Breen

Updated on: April 23, 2024 / 8:45 PM EDT / CBS News

The most distant spacecraft from Earth has resumed sending data after a five-month gap, NASA said Monday. 

NASA's Voyager 1 spacecraft was launched in 1977, about two weeks after the launch of its twin, Voyager 2. The spacecraft has spent over 45 years studying the outer solar system and has made flybys of Jupiter and Saturn and traveled more than 46,000,000,000 miles . 

In November 2023, the spacecraft stopped sending "readable science and engineering data," NASA said in a news release . Mission controllers were able to determine that Voyager 1 was still receiving commands from Earth and operating normally, but the science data could not be read and researchers did not know the status of the craft's onboard engineering systems. 

Last month, the craft's engineering team was able to confirm that the issue was related to one of the three onboard computers that make up Voyager 1's flight data subsystem. That system is what packages science and engineering data into a readable format before sending it to Earth. The team determined that "a single chip responsible for storing a portion of the (system's) memory," including some computer software code, wasn't working. 

The chip couldn't be repaired and the code was too large to place in one new location, NASA said, so the team worked to relocate the affected code into multiple sections of the flight data subsystem. It took weeks to repackage the code, NASA said, and last Thursday, the new location was communicated to Voyager 1. 

It takes about 22 and a half hours for a radio signal to reach Voyager 1 in interstellar space , or the space between stars, NASA said. On Saturday, the spacecraft's mission team received a response, confirming that the code modification had worked. 

Engineers celebrated receiving new data for the first time in almost half a year, but the work isn't done yet. NASA said that in the coming weeks, the mission team will "relocate and adjust the other affected portions" of the software, including portions that will start returning science data. Meanwhile, Voyager 2 continues to operate with no issues, and both craft will continue to report back on the distant reaches of the solar system.

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.
