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the most wonderful story of our time how the Voyagers were built not to fail and the ground teams involved maintaining outdated unique systems to keep these two gems moving on in space.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.
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.
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.
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?" 😅
@benjaminhanke79 I may be wrong, and it was Mariner. Wish I'd made notes at the time, because he had some fascinating stories. He also mentioned experiments with radar that weren't space related. The key aspect of the story was using paper to manually map an image being received. Making do with what you have. 🙂
This just blows my mind, what clever people they all are. From the person who realized the planetary alignment, the navigators, engineers to the people tracking it today and FIXING V1 it from all that distance. Meanwhile Voyager 2 launched on my 3rd birthday, he is like my Life Probe. Keep going V2!!
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.
Fantastic interview. I just watched the Prime documentary, "It's Quieter in the Twilight" on the Voyager 2 team. To me, what is more impressive than the considerable scientific achievements of the spacecraft is the human element, the scientists and engineers who have spent decades on these missions. I am in awe of them. Their dedication and commitment are inspiring. They humanize our efforts in robotic space exploration. Thank you, NASA JPL, for sharing their stories with us. Ad Astra, et Ultra!!🌌📡🛰
Urodziłem się w 1983 r. O misji Voyager dowiedziałem się jako dziecko w 1995 r. To tak ambitna misja , że rozbudziła i rozbudza moją wyobraźnię wciąż o wszechświecie ,gwiazdach . Nie wyobrażam sobie straty lub wyłączenia tej misji .
Based on the questions, sounds like most people think these spacecraft are out there with full power and all systems fully running. Seems like no one knows the current systems and power status.
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.
We are currently in the process of uploading the communication at a power level of 20 kW. It is important to note that this is the specified power level, and we will not be proceeding with the upload at 100 kW. Thank you for your understanding.
An incredibly disappointing presentation for one of my favourite spacecraft - the other being the LEM. No mention of the late great Ed Stone either. I was hopeful of much more technical detail from the doyens of interplanetary and interstellar spacecraft design but alas...
Here's a more technical question: how do the electronic components that have limited lifetime, like capacitors and batteries, have survived for so many years?
After the Voyager flybys of Jupiter and Saturn, we built larger, more capable spacecraft that would orbit those planets for years to study them in more detail: Galileo, Cassini, Juno. More are being built right now. Uranus and Neptune haven't had dedicated missions yet. Because those planets are so far away, they're hard to reach. We did more flyby missions too: New Horizons, to Pluto and the Kuiper Belt. We did flyby missions on targets in the asteroid belt too. A new interstellar mission is being studied at the moment by JHUAPL. These missions are difficult to get approved: you have to wait 25 years before the first results come in.
📌I'm 44 and I love NASA 😎👍 Voyager 1 and 2 is an Amazing space exploration story ❤ "Old technologies stand longer throughout time, than almost all those recently made."
Yo! Why are those 2 duking it out on camera?? You can see it in their micro expressions! Lol... his jaw clinches, her eyes roll and face goes mute so many times. Lets focus on the presentation of the material for everyone in the world and not the engineer vs scientist ongoing rivalry
"The two Voyager's are flying where no spacecraft have flown before" - This is incorrect. She should have said: "The two Voyager's are flying where no HUMAN MADE spacecraft have flown before"
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.
Right? They dumbed it down way too much. I would have liked them to also present some examples what they actually changed in code. Give us some mnemonics for the assembly and explain a little. 😕 Not this "it's a letter" nonsense.
Because the average American is a potato brain. If you don't believe me stop a random person on the street and ask them what part of the electromagnetic spectrum is being used to communicate with the Voyager 2 probe. Very simple deduction skills could come to an answer.
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
More powerful computers can only do so much. The Voyager mission is limited by how fast it can send its data, which is currently at 40 bits per second. This can only be improved by using larger antennas.
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.
Communication was in fact lost with Voyager 1: for months, it was sending no data at all. Getting it back to sending science data was a triumph of engineering. These people are verifiably not crazy, and are in fact talking to Voyager 1 and not anything else.
@zounds010 😆 Voyager 1 is my property. It had left the solar system decades ago. In 2004 I set a spacecraft to go retrieve it and restore its electronics and propulsion. There has been no problems communicating with Voyager 1 since then. You are probably talking to a ghost of an electronic signal from Voyager 1 when it was in the solar system. Voyager 1 has accelerated to >15 times the speed of light., since the engine was fixed in 2003. I doubt there's any problems with the communications, you're probably not talking to Voyager 1.
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 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.

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!

I've seen a photo of that hand drawn plot, it must have been in one of Scott Manley's videos
@benjaminhanke79 cool! I didn't know that existed.
@@theharper1 I may have mixed that up and it could have been a mariner probe. But wasn't Pioneer built from leftover mariner hardware?
@benjaminhanke79 I may be wrong, and it was Mariner. Wish I'd made notes at the time, because he had some fascinating stories. He also mentioned experiments with radar that weren't space related.

The most human mission up to date. This is humbling.
a 47 minute video on fixing Voyager?!? I got chills just reading the title!!
This just blows my mind, what clever people they all are.

Voyagers 1 and 2...The little probes that could.
Thank you very much for this video, great presentation and explanation.

As I was watching, I kept being reminded of the movie Space Cowboys. This was brilliant.
Thanks for this. It was enthralling

So much better than the 'zoom' lectures. Thanks for not phoning this one in.
That was great!
2:00 starts
Wonderful
herzlichen glückwunsch its amazig i´m happy wiht you THANKS and all mery chrismass🥰🥰❤❤❤❤👏👏👏👏👍

Good
What does power a 50 year old craft that is supposedly outside the solar system now? How could any power be generated with no atmosphere or light?
The heat produced by the decay of Plutonium 238.
Basicaly they did a bad sector repair or isolation?
No mention of Carl Sagan 3/4s thru the video????
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.
As a retired engineer I’d be happy this was the first hardware failure in 47 years.
The space age was just 20 years old when they launched, and they are still going.
We are currently in the process of uploading the communication at a power level of 20 kW. It is important to note that this is the specified power level, and we will not be proceeding with the upload at 100 kW. Thank you for your understanding.

Here's a more technical question: how do the electronic components that have limited lifetime, like capacitors and batteries, have survived for so many years?
Yes I Plan on using a Hummer X Sputter machine
Why haven't we sent new voyagers out with up to date technology?
After the Voyager flybys of Jupiter and Saturn, we built larger, more capable spacecraft that would orbit those planets for years to study them in more detail: Galileo, Cassini, Juno. More are being built right now. Uranus and Neptune haven't had dedicated missions yet. Because those planets are so far away, they're hard to reach.

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.
was it just a semicolon?
I'm disappointed.
I expected a much deeper dive into Voyager's hardware and more details on how the failure was understood and fixed.
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?”
And will any new Voyager-like projects be launched? 😜
Why doesn't NASA bring ants for testing on Mars, whether they can survive or not?
"The two Voyager's are flying where no spacecraft have flown before" - This is incorrect.
She should have said: "The two Voyager's are flying where no HUMAN MADE spacecraft have flown before"
Please change this format. Not all of us are Americans who need it presented like a game show.
Serial Data Communications... 🙂
We should have dozens of these probes still preforming flybys. It's insane and sad that we just stopped.
Instead of doing flybys that only give us a few days worth of science, we launched more capable spacecraft that orbited Jupiter and Saturn for years.
And yet we can't build anything like this anymore.
Why? There are two rovers on Mars right now, one of them operating for 12 years.
Oh my goodness, I think they'll need to replace the capacitors.

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
