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the most wonderful story of our time how the Voyagers were built not to fail and the ground teams involved maintaining outdated unique systems to keep these two gems moving on in space.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 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.
This was so interesting, I loved hearing how problem-solving helped figure out the issues and that communication with Voyager resumed. It's incredible that technology is almost 50 years old and is still working while our latest cell phones die a couple years later. I appreciate the information on the Golden Record as many people today are not aware of its existence.
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.
I had the chance to talk to an engineer who worked on receiving signals from the Pioneer probes here in Australia. He said that NASA refused to pay for a display to allow them to see the images as they were coming in. However, the bit rates were so slow that they were able to plot the data on paper manually as it came in. They were on the phone to NASA at the time, and telling them that there were starting to see the edge of a crater, and the NASA people said "...but you don't have a screen, how are you seeing that?" 😅
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.
I did write in assembly language in the 1970's in college. I did it only because I wanted to be able to work in it. I did use in the late 1970's for a job I had. NOT FUN.
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.
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.

I grew up studying space and reading space books with pictures from Voyager 1 and 2. This was awesome seeing Dr. Spilker on here.
Voyagers 1 and 2 great missions from JPL. Congratulations. Thanks so much. Your're great! ❤❤❤
This was wonderful! I got to tour JPL once and loved it. Go Voyagers!

Voyagers 1 and 2...The little probes that could.

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!
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 most human mission up to date. This is humbling.
judgmentcallpodcast covers this. NASA Restores Voyager 1 Communications
This is so cool. It's like a broadcast from the future, but we're here now :)

A hug thanks ❤
2:00 starts
So much better than the 'zoom' lectures. Thanks for not phoning this one in.
Thanks for this. It was enthralling
Why haven't we sent new voyagers out with up to date technology?

Wonderful
Thanks,congrats😊.
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?”
Yes I Plan on using a Hummer X Sputter machine
Good
Serial Data Communications... 🙂

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.

Hi There Do drop in at times. LOL
Basicaly they did a bad sector repair or isolation?
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.
Why doesn't NASA bring ants for testing on Mars, whether they can survive or not?
Oh my goodness, I think they'll need to replace the capacitors.
We should have dozens of these probes still preforming flybys. It's insane and sad that we just stopped.
🛰️🌌
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.

What's the incorrect information?
So, we're talking to aliens, illegal aliens?
