- Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. For two decades after launch, the spacecraft were planetary explorers, giving us up-close views of the gas giants Jupiter, Saturn, Uranus, and Neptune. Now, as they reach distances far beyond the hopes of their original designers, the aging spacecraft challenge their team in new ways, requiring creative solutions to keep them operating and sending back science data from the space between the stars.
As we celebrate the 45th anniversary of these epic explorers, join Voyager deputy project scientist Linda Spilker and propulsion engineer Todd Barber for a live Q&A. - Věda a technologie
Everything about this project is uplifting! Thank you for sharing. Congrats to everyone who worked on Voyager.
What a brilliant talk. Love listening to Linda talk about her work 🙏
I was born the day voyager 1 launched Aug 20th 1977!! pretty cool birthday knowing I was born the same day the farthest human object was launched! which until we find a much faster way to travel will remain a fact! cheers From Slc Utah!
Happy belated birthday to you!
What a cool birthday to have!
@@osmia ah thank you!! 😊 cheers!
Happy birthday voyager
Voyager ❣️❣️❣️ the little spacecrafts that could
They weren't really that little each space craft was the size of a school bus
Happy birthday Voyagers 1&2!
Happy 45th and here's to another 45! 🙂
Thank you for sharing.
Everything about the Voyager projects is just amazing, especially that they are still working for so long and so far away. Congratulations to the creators and the sustainers of these missions.
Amen. What a treasure JPL is.
It still absolutely blows me away that we have sent probes to interstellar space
Technically they are in interstellar space, because they are outside of the heliosphere and are now exposed to the full force of galactic cosmic rays. But they will take at least 20,000 years for them to pass through the Oort cloud and leave the Solar System behind to enter the galaxy at large.
Happy 45th Birthday!
Space, the final frontier.
These are the voyages of two NASA probes. 🛰🛰
Their on-going mission:
To explore the outer planets,
To seek out new planetary and interstellar data,
To boldly go where no probes have gone before!
1. Happy birthday 🎈
2. Great q&a 👍
3. Where did Todd get his shirt???
Thank you for these new up dates on the Voyagers. They remind me of Carl Sagan. So I genuinely appreciate it.
Agree
Brilliant series Cosmos
@@seanh4841 yes Cosmos was brilliant
That was awesome, thank you for sharing your information
Those probs are amazing and continue to collect great science data. Nice to know there are still lots of people who are interested in them even to this day.
Thank you, that was an enlightening interview! So nice to see the real size of the Voyager. I wish we could have more information about this amazing spacecraft, like... Which computers are in, is there any autonomous capabilities? Which protocols does it use to communicate with the earth? How exactly their propulsion system works? Ion thrusters? What about the batteries? Are there any nuclear power batteries like in the mars rover? How the battery lasts so long? Is there any ground computer communicating with the probe 24/7? What type of algorithms does it run? Is there any autonomous algorithm on earth sending directions to the probe? May you please show us the mission control center? Show us the antennas? What are the instruments present on the probe? The camera specifications... Which sensors are still alive? What can they measure? Where can we see the entire path that the probes took? Who wrote the code that runs the probe? How about the redundancy? How is it administrated? Is there a master computer switching between them? Can the Voyagers communicate with each other in case one fails to communicate with earth? Thank you very much for inspiring so many generations!!
It is remarkable that the Voyagers still work in their 45 year-old tecnhology while here on Earth we are 45 years in the future (since 1977), and we still are capable of talking to the ships in their old language and technology.
That is something I would like to learn about.
This mission is breathtaking, and this is one of the reason why I love it so much 💖 like, literally, there is always something to catch up with when a problem arises. Whether it's a backup instrument, an alternative option, a little (a lot) of patience and thought,... It's just amazing how everything (or almost everything) always works out in the end when it comes to these probes 💕
(7:51) I've literally shouted out loud, my roommates asked me if everything was alright 😂 and I said YES, IT IS , because that so awesome ! These probes can't be stopped, and of course, a really huge thanks to all the persons who tried everything they could to bring down this problem. I can't even express all my happiness and my love for these spacecrafts there, it's totally impossible with just some words 💕
You are awesome guys ! 45y on this awesome project !
Wow this was very interesting and captivating!
Fascinating! Thanks.
Thanks for sharing, it has been a great journey so far considering the twins have travelled! Kudos to the Voyager team....
I love everyone at NASA!!!
@20:00 I think it’s worthwhile mentioning that both probes communicate using the DSN network which allows for communication to and from earth 🌍
Excellent documentary and insights
Happy birthday 🎂!
Fantastico semplicemente
Miranda looks awesome!
61,500 kph or 38,214 mph, travelling for 45 years and we've just recently left our Solar System. It's an interesting perspective on the size of our wee corner of the galaxy. With the new James Webb data coming in and finding CO2 from an exoplanet the voyage of scientific knowledge continues to excite.
Thank you for the update and for everyone's hard work at NASA.
I was on the mission control team for the first 3 encounters. Brings back memories.
Congratulations
Wow what a lucky Lady to see what you have done to now pure history very exciting and thanks to yourself and lady's and gentlemen we have this now keep the good great work on going Thanks Allen God bless you
Great these old timers tec. still has life, like my 34year car.
Grazie Carl Sagan thank you
4:20 amazing pic
I missed such a livestream.
Interesting that both Voyagers ended up near the bow of the heliosphere, 2:27. I didn't know that before.
Linda Spilker is actually a year or two younger than I am. She's done so much more with her life, though. Hey, she's got her own wikipedia entry!
I have a question. If one of the probes is 'closer' to earth then the other, and the distance is 'too far' from Earth, could Voyager 1 or Voyager 2, 'relay' the other probes data, to Earth, so instead of losing 'everything' from either spacecraft, at least we would be able to get 'some' data back. Is this possible? Is there a system that can be modified to relay this information? Thank you for your response.
Unfortunately both probes are not in contact with each other, and do not have enough power generation capability to receive and then relay the other satellite's data to the Deep Space Network. Both probes are almost as far apart from each other as they are distant from the Earth.
Wow 40,000 years and still 2 light years away from Alpha Centauri.
It’s crazy to think about the advancement of human civilisation till the voyagers reach Alpha Centauri !!
When will it get too far for us to reach the signal from the voyagers on the deep space network?
I wonder if people will catch it up.
I assume there are heaters on the propellant tank and the lines to the thrusters. Perhaps the RTG's are not able to supply enough power for the heaters and the other systems at the same time anymore. The temperatures of the spacecraft must be well below 30 or 40 K. In the Oort Cloud they will be at 4 K, and long dead when they get there.
What engine powered does voyager spacecraft have?
They call those satellites bundled together an array to be able to get those small signals
I know voyager captured the 10th planet where is the image of it?
Where can I download the actual binary data please?
Vger 🙂

Isn't there some relativity in the time on Voyager 1 and 2 and on earth? So how long does the spacecraft reckon since launch?
Calculated about 1 second after 45 years!
Just a thought, I'm guessing that the angular spread of the Voyagers signals by the time it reaches Earth is considerably larger than the diameter of the Earth (please ignore all this if that is not the case). This would mean that their signals have now gone past the Earth and headed in to deep space for decades. Anything intercepting those signals would see them as coming from earth's direction. A constant beacon of our existence.
Actually, the way electromagnetism works, the signal goes by Earth (but diminished) anyway so it is just weaker.
Retired JPL Mission Controler
@@garylcamp weaker of course but how far past the earth before the signal becomes too weak to detect?
The question about casting a wide net with the radio signals got a bit of a bungled answer. No it is not pinpoint it is much wider than earth in that direction and much wider than spacecraft in the other. 8GHz and 3.7 metre dish gives maybe 0.5 degree. Earth appears as diameter?

What would be if Voyager 1 got success in its ultimate mission?
It has already surpassed its mission! Now it’s doing extracurricular activities 😉
@@courtney-ray lol, bring him back and it would take another 45 years so. He is not capable of performing longer extracurricular activities any more. Though, I want someone soon find him and get the golden disk before it might hit any possible crash causing object.
Well beem me up Scottie
Another 2 billion miles and V1 would have equaled 1 light day of travel(16,070,400,000 miles:).
👍🏾👍
Thank you!
Quando cesserà il segnale x
*Would be great if **#Google** had some of these techs. I just today got the email about this video and I’ve already have watched it.* 🤔😞
3:38 Start.

Based on speed and distance traveled, how "out of sync" are the probes with Earth, in relativistic terms? Negligibly? Not at all? Perhaps the probes are wondering why we're celebrating 45 years so "early". :-P
Bon voyage Carl Sagan
November 2026!
A silly question if I may, please….I don’t understand why you have to shut some spacecraft down? I assume they use either nuclear power or solar power or both, so as long as those sources of power are available, cannot the spacecraft go on operating? Seems a terrible waste of resources shutting down such expensive craft!

Grand Tour voyager 1 voyager 2
7:40 amazing . yet rubbish digital dolby atmos avr's mobile phones rubbish and yet these voyager spacecrafts 1 and 2 still working . power may run out in 2025 ? analogue circuity pushed to it's working operating technical tolerances , amazing
Miles? srsly? Must have been recorded in 1977 🤣
The vastness of space, voyagers have been traveling 38,000 miles an hour for 45 years and are barely 1 light day away from earth….they will need to travel another 45,000 years before they reach the next celestial object. If the earth is ravaged by catastrophe, it’s still 1000 times easier to survive here than anywhere we can get to in space. Just saying.
Doesn't Einstein give the solution for displacement in space without ejecting mass?
When you give energy, speed to a mass, the mass increases. (That's why we can't reach the speed of light). can't we give a eg diamond so much rotational energy that the mass becomes larger? Then move this diamond from the top to the bottom of the vehicle and then convert the rotational energy back into electricity and bring the diamond (with smaller mass) back to the top of the vehicle. And repeat the process.
It will not be easy in practice, but possible in theory. If necessary, use a carbon molecule. They can process a lot of rotational energy without degrading. please disprove my theory, or go and exploit space.
understand that both Voyager are pretty much used their energy. Why can’t we ask our friends from Centara to help with the power for them? I know that our government has a good relationship with them
