Fixing Voyager: How NASA Restored Communications with Voyager 1 from Across the Solar System

- After more than four and a half decades exploring our solar system and beyond, Voyager 1 has had a challenging year. In November 2023, the spacecraft suddenly and unexpectedly stopped sending scientific and engineering data back to Earth, beginning a months-long process to diagnose and problem-solve with a spacecraft billions of miles away and built on systems designed in the 1970s.
Join us for a live talk to learn how the Voyager team at JPL - both current and retired - used an impressive combination of modern and past resources, detective work, trial and error, and decades of experience to solve the problem.
Launched in 1977, Voyager 1 and its twin Voyager 2 are the only spacecraft ever to operate outside the heliosphere and continue to provide valuable scientific data from interstellar space.
Speakers:
Kareem Badaruddin, Voyager mission manager, NASA JPL
Dr. Linda Spilker, Voyager project scientist, NASA JPL
Host:
Gregory Smith, communications and education directorate, NASA JPL
Co-host:
Calla Cofield, media relations specialist, NASA JPL

I grew up studying space and reading space books with pictures from Voyager 1 and 2. This was awesome seeing Dr. Spilker on here.
This was wonderful! I got to tour JPL once and loved it. Go Voyagers!
Voyagers 1 and 2 great missions from JPL. Congratulations. Thanks so much. Your're great! ❤❤❤
Top👍... It's like talking to an old friend very far far away... Who, after many years, is still giving you so much information... Wonderful mission!
Voyagers 1 and 2...The little probes that could.
This has been the most wonderful story of our time how the Voyagers were built not to fail and the ground teams involved maintaining outdated unique systems to keep these two gems moving on in space. Who known what the next chapter is for the Voyagers, crossing fingers we get the next 5 or 10 years more our of them.
The most human mission up to date. This is humbling.
A hug thanks ❤
a 47 minute video on fixing Voyager?!? I got chills just reading the title!!
Thank you very much for this video, great presentation and explanation.
The last time I looked at it I think the signal was -158.3 dbm. If I remember correctly it might be about a year or two old data the signal amplifiers and the noise Gates that they had to build to filter down that low is just absolutely amazing in my mind. At that low of a signal to noise ratio a single drop of rain could make the difference between hearing the Voyager craft and not. It's amazing they have a little leaf blower style of fan blowing on a clear piece of plastic stretched over the receiver horn/ waveguide filter plate to keep moisture from buildup from interfering with the receiver it's crazy.. but the fine people at Nasa always seem to find a way. Fun fact the transmitter that we use is kept in Canberra Australia and I have always always wanted go and tour that facility. We're talking a 6-ft tall Klystron tube is the final PA. The on-site General Electric Generators that they have for emergency backup power or just staggering down there.
Thanks guys for the talk. Very interesting to here about everything. I graduated high school back in 1977 . Lot of time has passed for sure. Keep up with them as long as you can. Keep on space trucking.
Thanks for this. It was enthralling
This is so cool. It's like a broadcast from the future, but we're here now :)
We should have dozens of these probes still preforming flybys. It's insane and sad that we just stopped.
Wonderful
2:00 starts
Thanks,congrats😊.
Yes I Plan on using a Hummer X Sputter machine
This same conversation likely happed in Egypt and Rome in the last 2,000 - 4,500 years. “How exactly did we build that pyramid/colosseum?”
Good
Why is every NASA update presented like the audience is strictly 8-year-olds? “Hey kids! Check out this neato stuff!” Omg… I can’t even wade through it to get to the meat of the update.
Eyyyy, did you wind up using the Berlekamp-Massey decoder again? Not sure how relevant it is to deep space communications these days. Ol Uncle Elwyn is the Berlekamp half of that error correction equation.
Hi There Do drop in at times. LOL
Serial Data Communications... 🙂
Basicaly they did a bad sector repair or isolation?
I believe the worst case scenario would be not to find letters from the space craft in the mail box...not letters composed of gibberish.
And will any new Voyager-like projects be launched? 😜
The space age was just 20 years old when they launched, and they are still going.
Oh my goodness, I think they'll need to replace the capacitors.
THERE ARE NO D.Js IN SPACE. 👉👽👈
i, gary of the landmass known as scotland, claim the Heliosphere and all therin as my dominion. You all owe me some tax dollar.
I wonder if today’s Apple silicon would be used in these probes how much more efficient and powerful it would make them. Those old computers must be very poor in today’s standards.
radiation would destroy it and corrupt its memory.
apple chips are still power guzzlers compared to embedded systems. Theyre also not radiation hardened in anyway.
meaning they literally would not be trustworthy enough to run the flight controller software in a passenger plane
I don't know why anybody thinks communication was ever lost with Voyager One. I'm hearing a lot of incorrect information about the Voyager spacecraft. Those people might just be crazy and think they're talking to Voyager spacecraft, but are not.
What's the incorrect information?
So, we're talking to aliens, illegal aliens?
