Voyager 1 whizzes through interstellar space at 17 kilometers per second.

On 14 November 2023, NASA’s interstellar space probe Voyager 1 began sending gibberish back to Earth. For five months, the spacecraft transmitted unusable data equivalent to a dial tone.

In March, engineers discovered the cause of the communication snafu: a stuck bit in one of the chips comprising part of Voyager’s onboard memory. The chip contained lines of code used by the flight data subsystem (FDS), one of three computers aboard the spacecraft and the one that is responsible for collecting and packaging data before sending it back to Earth.

JPL engineers sent a command through the Deep Space Network on 18 April to relocate the affected section of code to another part of the spacecraft’s memory, hoping to fix the glitch in the archaic computer system. Roughly 22.5 hours later, the radio signal reached Voyager in interstellar space, and by the following day it was clear the command had worked. Voyager began returning useful data again on 20 April.

NASA engineers managed to diagnose and repair Voyager 1 from 24 billion kilometers away—all while working within the constraints of the vintage technology. “We had some people left that we could rely on [who] could remember working on bits of the hardware,” says project scientist Linda Spilker . “But a lot of it was going back through old memos, like an archeological dig to try and find information on the best way to proceed.”

Minuscule Memory

Voyager 1 and its twin, Voyager 2—which also remains operational—were launched nearly 50 years ago, in 1977, to tour the solar system. Both spacecraft far surpassed their original missions of visiting Jupiter and Saturn, and in 2012, entered interstellar space .

“That mission literally rewrote the textbooks on the solar system,” says Jim Bell , a planetary scientist at Arizona State University and author of a book recounting 40 years of the mission. “We’ve never sent anything out that far, so every bit of data they send back is new.” The 1960s and 1970s technology, on the other hand, is now ancient.

Decades after the tech went out of vogue, the FDS still uses assembly language and 16-bit words . “These are two positively geriatric spacecraft,” says Todd Barber , a propulsion engineer for Voyager. Working to fix the issues, he says, is “like palliative care.”

To first diagnose the issue, NASA’s engineers first tried turning on and off different instruments, says Spilker. When that proved unsuccessful, they initiated a full memory readout of the FDS. “That’s what led to us finding that piece of hardware that had failed and that 256-bit chunk of memory,” she says. In one chip, the engineers found a stuck bit, fixed at the same binary value. It became clear that the chip was irreparable, so the team had to identify and relocate the affected code.

However, no single location was large enough to accommodate the extra 256 bits. “The size of the memory was the biggest challenge in this anomaly,” says Spilker. Voyager’s computers each have a mere 69.63 kilobytes of memory.

To begin fixing the issue, the team searched for corners of Voyager’s memory to place segments of code that would allow for the return of engineering data, which includes information about the status of science instruments and the spacecraft itself. One way the engineers freed up extra space was by identifying processes no longer used. For example, Voyager was programmed with several data modes—the rate at which data is sent back to Earth—because the spacecraft could transmit data much faster when it was closer to Earth. At Jupiter, the spacecraft transmitted data at 115.2 kilobits per second; now, that rate has slowed to 40 bits per second, and faster modes can be overwritten. However, the engineers have to be careful to ensure they don’t delete code that is used by multiple data modes.

Having successfully returned engineering data, the team is working to relocate the rest of the affected code in the coming weeks. “We’re having to look a little harder to find the space and make some key decisions about what to overwrite,” says Spilker. When their work is completed, the Voyager team hopes to return new science data, though unfortunately, all data from the anomaly period was lost.

Built to Last

The cause of the stuck bit is a mystery, but it’s likely the chip either wore out with age or was hit by a highly energetic particle from a cosmic ray. Having entered interstellar space, “Voyager is out bathed in the cosmic rays,” Spilker says. Luckily, the spacecraft was built to take it, with its electronic components shielded from the large amount of radiation present at Jupiter. “That’s serving us quite well now in the interstellar medium.”

When Voyager was built, the 12-year trip to Uranus and Neptune alone was a “seemingly impossible goal for a 1977 launch,” says Barber. The longevity of Voyager is a testament of its engineering, which accounted for many contingencies and added redundancy. The mission also included several firsts, for example, as the first spacecraft with computers able to hold data temporarily using volatile CMOS memory. (An 8-track digital tape recorder onboard stores data when collected at a high rate.)

Importantly, it was also the first mission with a reprogrammable computer. “We take it for granted now,” Bell says, but before Voyager, it wasn’t possible to adjust software in-flight. This capability proved essential when the mission was extended, as well as when issues arise.

Going forward, the Voyager team expects to encounter additional problems in the aging spacecraft—though they hope to make it to the 50-year anniversary before the next one. “With each anomaly, we just learn more about how to work with the spacecraft and are just amazed at the capabilities that the engineers built into it using that 1960s and ’70s technology,” Spilker says. “It’s just amazing.”

I worked with COSMAC and similar rudimentary processors in the early 70’s so was curious to learn how they solved this problem. The nearest it got was “they initiated a full memory readout of the FDS.” But if the telemetry was faulty how did the get the readout?

NASA's Voyager 1 spacecraft finally phones home after 5 months of no contact

On Saturday, April 5, Voyager 1 finally "phoned home" and updated its NASA operating team about its health.

NASA's interstellar explorer Voyager 1 is finally communicating with ground control in an understandable way again. On Saturday (April 20), Voyager 1 updated ground control about its health status for the first time in 5 months. While the Voyager 1 spacecraft still isn't sending valid science data back to Earth, it is now returning usable information about the health and operating status of its onboard engineering systems. 

Thirty-five years after its launch in 1977, Voyager 1 became the first human-made object to leave the solar system and enter interstellar space . It was followed out of our cosmic quarters by its space-faring sibling, Voyager 2 , six years later in 2018. Voyager 2, thankfully, is still operational and communicating well with Earth. 

The two spacecraft remain the only human-made objects exploring space beyond the influence of the sun. However, on Nov. 14, 2023, after 11 years of exploring interstellar space and while sitting a staggering 15 billion miles (24 billion kilometers) from Earth, Voyager 1's binary code — computer language composed of 0s and 1s that it uses to communicate with its flight team at NASA — stopped making sense.

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

In March, NASA's Voyager 1 operating team sent a digital "poke" to the spacecraft, prompting its flight data subsystem (FDS) to send a full memory readout back home.

This memory dump revealed to scientists and engineers that the "glitch" is the result of a corrupted code contained on a single chip representing around 3% of the FDS memory. The loss of this code rendered Voyager 1's science and engineering data unusable.

The NASA team can't physically repair or replace this chip, of course, but what they can do is remotely place the affected code elsewhere in the FDS memory. Though no single section of the memory is large enough to hold this code entirely, the team can slice it into sections and store these chunks separately. To do this, they will also have to adjust the relevant storage sections to ensure the addition of this corrupted code won't cause those areas to stop operating individually, or working together as a whole. In addition to this, NASA staff will also have to ensure any references to the corrupted code's location are updated.

On April 18, 2024, the team began sending the code to its new location in the FDS memory. This was a painstaking process, as a radio signal takes 22.5 hours to traverse the distance between Earth and Voyager 1, and it then takes another 22.5 hours to get a signal back from the craft. 

By Saturday (April 20), however, the team confirmed their modification had worked. For the first time in five months, the scientists were able to communicate with Voyager 1 and check its health. Over the next few weeks, the team will work on adjusting the rest of the FDS software and aim to recover the regions of the system that are responsible for packaging and returning vital science data from beyond the limits of the solar system.

Voyager 1 was in crisis in interstellar space. NASA wouldn’t give up.

NASA engineers spent months doggedly trying to fix a computer on Voyager 1, a spacecraft launched in the 1970s that’s now exploring interstellar space.

For the past six months a team of engineers at NASA’s Jet Propulsion Laboratory has been trying to fix a glitchy computer. Three things make the repair job challenging:

The computer is highly customized and unlike anything on the market today.

It was built in the 1970s.

And it is 15 billion miles away.

The computer is on Voyager 1, the most distant human-made spacecraft ever launched. Far beyond the orbit of Pluto, it is riding point for all humanity as it hurtles through interstellar space.

But on Nov. 14, Voyager 1 suddenly stopped sending any data back to Earth. While it remained in radio contact, the transmission had, as NASA engineers put it, “flatlined.” So began the greatest crisis in the history of the fabled Voyager program.

Voyager 1 and its twin, Voyager 2, launched in 1977 and in the years that followed obtained stunning close-up images of Jupiter and Saturn. Voyager 2 also flew by Uranus and Neptune and is the only spacecraft to have visited those ice giants. The Voyagers blew past the heliopause, where the solar wind abates and interstellar space begins, and continued to send back science data about particles and magnetic fields in a realm never before visited.

The two Voyagers are powered by the radioactive decay of plutonium-238, and in the near future that power source will be too feeble to keep the spacecraft warm and functioning. But for now, they have operational scientific instruments that are sending back otherwise unobtainable data on the composition of space beyond the heliopause.

Fixing Voyager 1 quickly became a priority for NASA, and especially for Jeffrey Mellstrom, who has been at JPL in Pasadena for 35 years and is the chief engineer in the astronomy and physics directorate.

Mellstrom took on the challenge even as he planned for retirement in the spring. In January, Mellstrom told a colleague, “The one thing I’m going to regret is if I retire before we solve Voyager 1’s problem.”

Like kicking a vending machine

After initial attempts to resolve the issue went nowhere, JPL leadership created a “tiger team” made of a multigenerational crew of engineers, some of them veterans of the lab and some born long after the Voyagers launched.

“We didn’t know how to solve this in the beginning because we didn’t know what’s wrong,” said Mellstrom, the team’s leader.

Voyager 1 has three computers. One is the attitude and articulation control system, which makes sure the spacecraft is pointed in the right direction. Another is the command control system, which handles the commands coming from Earth. The third is the flight data subsystem, which takes science and engineering data and packages it for transmission home.

Something had gone wrong somewhere in that trio of computers. Maybe a “cosmic ray” — a particle from deep space — had smashed into a computer chip. Or maybe a piece of hardware just got so old it ceased to work.

“All we had was incoherent data, garbled data,” said Suzanne Dodd, the Voyager project manager since 2010. Dodd has been at JPL for four decades, and in her early years she wrote computer code for Voyager 2’s encounters with Uranus and Neptune. She vividly remembers that first close-up look of Neptune and an image of the ice giant with its huge moon Triton in the background.

“We didn’t know what part of the spacecraft was involved with this,” Dodd said.

So they poked it. They sent commands to Voyager 1, trying to jolt it back to coherence. The team had a list of potential failures and figured that one of the commands might have the equivalent effect of kicking a vending machine.

Here is where the troubleshooting encountered an inviolable obstacle: the speed of light. Even at 186,000 miles per second, a command sent to Voyager 1 would take 22½ hours to arrive. Then the engineers would have to wait another 22½ hours for the spacecraft to send a response.

The planet Earth is kind of a pain, too, because it spins inconveniently on its axis and moves restlessly around the sun. To communicate with distant spacecraft, NASA relies on the Deep Space Network, three arrays of huge radio telescopes in California, Spain and Australia. The idea is that, regardless of Earth’s movement, at least one array can be pointed toward a spacecraft at almost any time.

The tiger team developed a pattern of sending a command on a Friday and waiting for the return signal on Sunday. Some dark days and weeks followed.

“None of those commands that we sent were able to make any discernible difference whatsoever,” said David Cummings, an advanced flight software designer and developer.

In late February, the team sent a series of commands to prod the flight data subsystem to place software in each of 10 different “data modes.” The team waited, hoping for a breakthrough. After two days, Voyager responded — still without data. Engineer Greg Chin circulated a technical chart and summarized the situation: “So, at this time, no joy.”

“It was unbelievably depressing,” Cummings said. “Luckily the story doesn’t end there.”

Cracking the code

Just a day after the “no joy” email, the team felt a surge of optimism.

JPL has specialists in radio transmissions, and they noticed that in some “modes” the return signal from Voyager 1 had been modulated in a pattern consistent with the flight subsystem computer producing data, though not in any normal format. The modulation suggested that the processor was functioning and supported the team’s conjecture that some of the memory had been corrupted.

“That was huge,” Cummings said. “The processor was not dead.”

Painstakingly, the team at last tracked down the origin of the problem: a bad memory chip holding one bit — the smallest unit of binary data — for each of 256 contiguous words of memory.

The flight data subsystem was built with 8K memory, or more exactly 8,192 bytes. (A modern smartphone has something like 6G memory, or 6 billion bytes.)

The engineers came up with a plan: They would move the software to different parts of the flight data subsystem memory. Unfortunately they couldn’t just move the 256 words in a single batch, because there was no place roomy enough for all of it. They had to break it down into pieces. And they’d have to proofread everything. It was tedious, error-prone work.

Cummings called a young JPL flight software engineer named Armen Arslanian: “Do you want to help me relocate Voyager code?”

Arslanian was the right person for the job. Just six years out of college, he knew how to write code for spacecraft, and he knew how to deal with “assembly language,” the coding that underlies the common languages used by programmers today. That’s the language of Voyager’s 1970s-era computers.

“I ended up needing that skill,” Arslanian said.

The JPL teams had documentation from the 1970s describing the function of the software, but often the descriptions were contingent on other information that could not be found. The team also lacked the tools to verify their coding. They had to do everything essentially by hand. It wasn’t like trying to find a needle in a haystack so much as like trying to examine every piece of hay for possible flaws.

The team prioritized the software for the engineering data so that they could fully restore communication with the spacecraft. If that worked, they could fix the science data later.

On April 18, the team sent a package of commands to the spacecraft and then waited. Two days later the spacecraft sent back the first intelligible engineering data in more than five months.

There is more work to be done, but the end is in sight. The engineers are still working on transferring the code that controls the scientific data. But they know how to do this. They found the problem, figured out the workaround and are just grinding through the code transfer.

Mellstrom and Dodd are fully confident that Voyager 1 has been saved. Mellstrom said he can retire without regret.

“The spacecraft is working,” Dodd said. “Go Voyager!”

An earlier version of this story incorrectly said Jeffrey Mellstrom and Suzanne Dodd are married. They are married to other people. This story has been corrected.

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

Nell Greenfieldboyce

This artist's impression shows one of the Voyager spacecraft moving through the darkness of space.

The last time Stamatios "Tom" Krimigis saw the Voyager 1 space probe in person, it was the summer of 1977, just before it launched from Cape Canaveral, Florida.

Now Voyager 1 is over 15 billion miles away, beyond what many consider to be the edge of the solar system. Yet the on-board instrument Krimigis is in charge of is still going strong.

"I am the most surprised person in the world," says Krimigis — after all, the spacecraft's original mission to Jupiter and Saturn was only supposed to last about four years.

These days, though, he's also feeling another emotion when he thinks of Voyager 1.

"Frankly, I'm very worried," he says.

Ever since mid-November, the Voyager 1 spacecraft has been sending messages back to Earth that don't make any sense. It's as if the aging spacecraft has suffered some kind of stroke that's interfering with its ability to speak.

"It basically stopped talking to us in a coherent manner," says Suzanne Dodd of NASA's Jet Propulsion Laboratory, who has been the project manager for the Voyager interstellar mission since 2010. "It's a serious problem."

Instead of sending messages home in binary code, Voyager 1 is now just sending back alternating 1s and 0s. Dodd's team has tried the usual tricks to reset things — with no luck.

It looks like there's a problem with the onboard computer that takes data and packages it up to send back home. All of this computer technology is primitive compared to, say, the key fob that unlocks your car, says Dodd.

"The button you press to open the door of your car, that has more compute power than the Voyager spacecrafts do," she says. "It's remarkable that they keep flying, and that they've flown for 46-plus years."

Each of the Voyager probes carries an American flag and a copy of a golden record that can play greetings in many languages. NASA/JPL-Caltech hide caption

Each of the Voyager probes carries an American flag and a copy of a golden record that can play greetings in many languages.

Voyager 1 and its twin, Voyager 2, have outlasted many of those who designed and built them. So to try to fix Voyager 1's current woes, the dozen or so people on Dodd's team have had to pore over yellowed documents and old mimeographs.

"They're doing a lot of work to try and get into the heads of the original developers and figure out why they designed something the way they did and what we could possibly try that might give us some answers to what's going wrong with the spacecraft," says Dodd.

She says that they do have a list of possible fixes. As time goes on, they'll likely start sending commands to Voyager 1 that are more bold and risky.

"The things that we will do going forward are probably more challenging in the sense that you can't tell exactly if it's going to execute correctly — or if you're going to maybe do something you didn't want to do, inadvertently," says Dodd.

Linda Spilker , who serves as the Voyager mission's project scientist at NASA's Jet Propulsion Laboratory, says that when she comes to work she sees "all of these circuit diagrams up on the wall with sticky notes attached. And these people are just having a great time trying to troubleshoot, you know, the 60's and 70's technology."

"I'm cautiously optimistic," she says. "There's a lot of creativity there."

Still, this is a painstaking process that could take weeks, or even months. Voyager 1 is so distant, it takes almost a whole day for a signal to travel out there, and then a whole day for its response to return.

"We'll keep trying," says Dodd, "and it won't be quick."

In the meantime, Voyager's 1 discombobulation is a bummer for researchers like Stella Ocker , an astronomer with Caltech and the Carnegie Observatories

"We haven't been getting science data since this anomaly started," says Ocker, "and what that means is that we don't know what the environment that the spacecraft is traveling through looks like."

After 35 Years, Voyager Nears Edge Of Solar System

That interstellar environment isn't just empty darkness, she says. It contains stuff like gas, dust, and cosmic rays. Only the twin Voyager probes are far out enough to sample this cosmic stew.

"The science that I'm really interested in doing is actually only possible with Voyager 1," says Ocker, because Voyager 2 — despite being generally healthy for its advanced age — can't take the particular measurements she needs for her research.

Even if NASA's experts and consultants somehow come up with a miraculous plan that can get Voyager 1 back to normal, its time is running out.

The two Voyager probes are powered by plutonium, but that power system will eventually run out of juice. Mission managers have turned off heaters and taken other measures to conserve power and extend the Voyager probes' lifespan.

"My motto for a long time was 50 years or bust," says Krimigis with a laugh, "but we're sort of approaching that."

In a couple of years, the ebbing power supply will force managers to start turning off science instruments, one by one. The very last instrument might keep going until around 2030 or so.

When the power runs out and the probes are lifeless, Krimigis says both of these legendary space probes will basically become "space junk."

"It pains me to say that," he says. While Krimigis has participated in space missions to every planet, he says the Voyager program has a special place in his heart.

Spilker points out that each spacecraft will keep moving outward, carrying its copy of a golden record that has recorded greetings in many languages, along with the sounds of Earth.

"The science mission will end. But a part of Voyager and a part of us will continue on in the space between the stars," says Spilker, noting that the golden records "may even outlast humanity as we know it."

Krimigis, though, doubts that any alien will ever stumble across a Voyager probe and have a listen.

"Space is empty," he says, "and the probability of Voyager ever running into a planet is probably slim to none."

It will take about 40,000 years for Voyager 1 to approach another star; it will come within 1.7 light years of what NASA calls "an obscure star in the constellation Ursa Minor" — also known as the Little Dipper.

If NASA greenlights this interstellar mission, it could last 100 years

Knowing that the Voyager probes are running out of time, scientists have been drawing up plans for a new mission that, if funded and launched by NASA, would send another probe even farther out into the space between stars.

"If it happens, it would launch in the 2030s," says Ocker, "and it would reach twice as far as Voyager 1 in just 50 years."

Voyager 1 stops communicating with Earth

Sign up for CNN’s Wonder Theory science newsletter.  Explore the universe with news on fascinating discoveries, scientific advancements and more .

NASA’s Voyager 1 spacecraft has experienced a computer glitch that’s causing a bit of a communication breakdown between the 46-year-old probe and its mission team on Earth.

Engineers are currently trying to solve the issue as the aging spacecraft explores uncharted cosmic territory along the outer reaches of the solar system.

Voyager 1 is currently the farthest spacecraft from Earth at about 15 billion miles (24 billion kilometers) away, while its twin Voyager 2 has traveled more than 12 billion miles (20 billion kilometers) from our planet. 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.

Initially designed to last five years, the Voyager probes are the two longest-operating spacecraft in history. Their exceptionally long lifespans 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.

But their unexpectedly lengthy journeys have not been without challenges.

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

But Voyager 1’s flight data system now appears to be stuck on auto-repeat, in a scenario reminiscent of the film “ Groundhog Day .”

A long-distance glitch

The mission team first noticed the issue November 14, when the flight data system’s telecommunications unit began sending back a repeating pattern of ones and zeroes, like it was trapped in a loop.

While the spacecraft can still receive and carry out commands transmitted from the mission team, a problem with that telecommunications unit means no science or engineering data from Voyager 1 is being returned to Earth.

The Voyager team sent commands over the weekend for the spacecraft to restart the flight data system, but no usable data has come back yet, according to NASA .

NASA engineers are currently trying to gather more information about the underlying cause of the issue before determining the next steps to possibly correct it, said Calla Cofield, media relations specialist at NASA’s Jet Propulsion Laboratory in Pasadena, California, which manages the mission. The process could take weeks.

The last time Voyager 1 experienced a similar, but not identical, issue with the flight data system was in 1981, and the current problem does not appear to be connected to other glitches the spacecraft has experienced in recent years, Cofield said.

As both Voyager probes experience new trials, mission team members have only the original manuals written decades ago to consult, and those couldn’t account for the challenges the spacecraft are facing as they age.

The Voyager team wants to consider all of the potential implications before sending more commands to the spacecraft to make sure its operations aren’t impacted in an unexpected way.

Voyager 1 is so far away that it takes 22.5 hours for commands sent from Earth to reach the spacecraft. Additionally, the team must wait 45 hours to receive a response.

Keeping the Voyager probes alive

As the aging twin Voyager probes continue exploring the cosmos, the team has slowly turned off instruments on these “senior citizens” to conserve power and extend their missions, Voyager’s project manager Suzanne Dodd previously told CNN .

Along the way, 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, 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.

While the team hopes to restore the regular stream of data sent back by Voyager 1, the mission’s main value lies in its long duration, Cofield said. For example, scientists want to see how particles and magnetic fields change as the probes fly farther away from the heliosphere. But that dataset will be incomplete if Voyager 1 can’t return information as it continues on.

The mission team has been creative with its strategies for extending the power supply on both spacecraft in recent years to allow their record-breaking missions to continue.

“The Voyagers are performing far, far past their prime missions and longer than any other spacecraft in history,” Cofield said. “So, while the engineering team is working hard to keep them alive, we also fully expect issues to arise.”

Share All sharing options for: Gagarin Cup Preview: Atlant vs. Salavat Yulaev

Gagarin cup (khl) finals:  atlant moscow oblast vs. salavat yulaev ufa.

Much like the Elitserien Finals, we have a bit of an offense vs. defense match-up in this league Final.  While Ufa let their star top line of Alexander Radulov, Patrick Thoresen and Igor Grigorenko loose on the KHL's Western Conference, Mytischi played a more conservative style, relying on veterans such as former NHLers Jan Bulis, Oleg Petrov, and Jaroslav Obsut.  Just reaching the Finals is a testament to Atlant's disciplined style of play, as they had to knock off much more high profile teams from Yaroslavl and St. Petersburg to do so.  But while they did finish 8th in the league in points, they haven't seen the likes of Ufa, who finished 2nd. 

This series will be a challenge for the underdog, because unlike some of the other KHL teams, Ufa's top players are generally younger and in their prime.  Only Proshkin amongst regular blueliners is over 30, with the work being shared by Kirill Koltsov (28), Andrei Kuteikin (26), Miroslav Blatak (28), Maxim Kondratiev (28) and Dmitri Kalinin (30).  Oleg Tverdovsky hasn't played a lot in the playoffs to date.  Up front, while led by a fairly young top line (24-27), Ufa does have a lot of veterans in support roles:  Vyacheslav Kozlov , Viktor Kozlov , Vladimir Antipov, Sergei Zinovyev and Petr Schastlivy are all over 30.  In fact, the names of all their forwards are familiar to international and NHL fans:  Robert Nilsson , Alexander Svitov, Oleg Saprykin and Jakub Klepis round out the group, all former NHL players.

For Atlant, their veteran roster, with only one of their top six D under the age of 30 (and no top forwards under 30, either), this might be their one shot at a championship.  The team has never won either a Russian Superleague title or the Gagarin Cup, and for players like former NHLer Oleg Petrov, this is probably the last shot at the KHL's top prize.  The team got three extra days rest by winning their Conference Final in six games, and they probably needed to use it.  Atlant does have younger regulars on their roster, but they generally only play a few shifts per game, if that. 

The low event style of game for Atlant probably suits them well, but I don't know how they can manage to keep up against Ufa's speed, skill, and depth.  There is no advantage to be seen in goal, with Erik Ersberg and Konstantin Barulin posting almost identical numbers, and even in terms of recent playoff experience Ufa has them beat.  Luckily for Atlant, Ufa isn't that far away from the Moscow region, so travel shouldn't play a major role. 

I'm predicting that Ufa, winners of the last Superleague title back in 2008, will become the second team to win the Gagarin Cup, and will prevail in five games.  They have a seriously well built team that would honestly compete in the NHL.  They represent the potential of the league, while Atlant represents closer to the reality, as a team full of players who played themselves out of the NHL. 

• Atlant @ Ufa, Friday Apr 8 (3:00 PM CET/10:00 PM EST)
• Atlant @ Ufa, Sunday Apr 10 (1:00 PM CET/8:00 AM EST)
• Ufa @ Atlant, Tuesday Apr 12 (5:30 PM CET/12:30 PM EST)
• Ufa @ Atlant, Thursday Apr 14 (5:30 PM CET/12:30 PM EST)

Games 5-7 are as yet unscheduled, but every second day is the KHL standard, so expect Game 5 to be on Saturday, like an early start.
