ScienceCasts: Voyager

Visit science.nasa.go... for the full story.
More than 30 years after they were launched, NASA's two Voyager probes have traveled to the edge of the solar system and are on the doorstep of interstellar space.

[@MarsFKA]

"A billion years from now, when everything on Earth we've ever made has crumbled into dust, when the continents are changed beyond recognition and our species is unimaginably altered or extinct, the Voyager record will still speak for us." Carl Sagan

[@pangtengchen]

Those Voyagers were the soul of Carl Sagan, it has been working until now and people like Leonefan did not appreciate it

[@jakeokada]

Amazing that Voyager is still making great scientific discoveries. I actually used some Voyager footage of Jupiter in my documentary about space travel, and it adds a sense of mystery to the film.

[@JazzKeyboardist1]

as voyager 1 traveled in faint starlight, no moon rose beyond the void and there was nowhere to go except where no man has gone before

[@Risjaiswal]

How can 11 people dislike such a video of human achievement

[@silentsniperrr]

With each passing day, that brave satellite furthers itself from its own home... 11.1 billion miles it has made its epic journey. As the edge of outer space dawns, it still remains a sign 30 years later of the progress of mankind. Godspeed, brave explorer.

[@ParaglidingManiac]

Voyager project looks so incredible. It's learning about the universe in RAW format :)

[@nuntana2]

Fantastic how she's still switched-on and able to send us data. Btw, the prime mission is done & dusted, a long time ago.

[@1337pino]

Man, the way this was narrated, I felt like I was a kid again and I was watching a show like Reading Rainbow. O_o

[@SeattleRexx]

After leaving out solar system, NASA will now refer to both Voyager spacecrafts as "Starships" rather than "spacecraft"! How cool!!

[@MrrANDOM34]

drifting through the stars doesn`t sound like a bad way to spend eternity

[@KoeSeer]

did you read about voyager 1? They (NASA) attached this probe with gold plated record. the record filled with sounds of nature, greetings, people talking, machinery, music if that's not enough, they also input the map of our solar system, our basic mathematics, alpahabet, numerical system, measurement system, etc etc... who knows who'll come knocking, friendly or not?

[@npntransistor299]

Radioisotope thermoelectric generators power the Voyager probes. The latest Mars rover also uses RTGs in addition to solar panels. Basically, radioactive material gives off heat and thermocouples turn this into electricity. We are still using the same technologies. Although, we now have better methods of implementing these technologies. I agree that this is amazing. The available power halves approximately every 87 years. Voyager 1 will be able to run a few instruments into 2025.

[@meithan]

@madmaniakid Actually, that is even more unlikely than the probe being found by another civilization, assuming they are out there. Not only are stars so small compared to the space between them, but an object's velocity must be *just right* for it to crash into a star (otherwise it would just orbit it). Consider this: when two galaxies collide, the stars they are made of don't collide with each other. There's so much empty space in a galaxy that they just pass right through each other.

[@VC106893]

Awesome video. Liked and shared, but please please, try to get the voice over quality a bit better?

[@galek75]

i would like the voyagers to come back. they could orbit earth as monuments to our great successes.

[@ScuddyGuitarsThings]

Yeah, that's kind of what I was getting at. I'm fascinated by what our sun would look like by comparison.

[@deltaray3]

Great video, but this sounded so much like a childhood bedtime story being read.

[@deltasword1994]

What would it crash into? There's hardly anything that far out. Maybe a little bit of space dust, but that's really it.

[@razzah1337]

is it just me or was the audio a bit off. the volume was variable.

[@Nino_J]

Golden Record? I hope they sent a golden record player! I agree with MWGrossman, this video sounds like one of my science class videos...........

[@CRTLALTBACKSPACE]

I wanna kiss the sky Just like a satellite I wanna sail among the stars And if you share my dream Come fly with me Over Jupiter and Mars At the speed of light Into the cosmic night I wanna ride around the sun Cause from the very start I give my heart I could never look back down Kisses in the sky I could never look down.....

[@yanksguy23]

@madmaniakid No. The Voyagers are tens of thousands of years from any star system. And space is so spread out that it's more likely that they will never, ever pass through any solar system again.

[@vinegarypoo]

nice info but the random 'flamboyance' of the voice is distracting from the awesomeness of this whole pioneer mission

[@Dyslexic-Artist-Theory-on-Time]

Nice! This is an invitation to see an artist theory on the physics of light and time! This can be based on just two postulates 1. Is that the quantum wave particle function Ψ or probability function represents the forward passage of time itself 2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual!

[@karjens41]

This is absolutely amazing! Thank you.. Though it makes me wonder why we were able to create these craft 30 years ago yet (according to Bolden) in the 21st century, we don't have the technology to get back to the moon without international help.

[@sgtunix]

Great vid. Great storytelling.

[@Molo9000]

@Zebonka Voyager 1 is now almost 3 times as far away as it was back in 1990 when the original Family Portrait was taken. I doubt u would be able to see the planets from this far away. A picture of our sun from that far away might be interesting though. Just a star among many stars.

[@nachowarrior1]

Wait, could the Voyager carry small voyager babies inside of them, and when the Voyager runs out of power, the babies get sent out? They should do that with new spacecrafts.

[@riahmatic]

It's 2011, how about some HD, Nasa!

[@19boozebelly81]

So it will take Voyager 1 about 40.000 years to reach the nearest star and therefore the next tiny possibility of intelligent life, so i think we can asume it's built for the long therm... what a bummer...

[@Hannodb1961]

How do they know Voyager is in a transition zone, and not already in inter-stellar space?

[@Triad72]

This audio is annoying, the volume keeps going up and down, as if the woman speaking is continuously moving to and from the microphone. Either that or that's how she speaks and in any case, it would have been much better had there been a more clear narration.

[@LizardYup]

It would be cool if 1 passed Gilese, the possible of another Earth like planet, and the other voyager passing Alpha Centurai, the closet star system to us.

[@StarTrekkie8472]

@AshleyBluewater2010 Consider that these probes were sent over 30 years ago!

[@SarahBCampbell]

Anyone else think the golden record is like a restraunt menue?

[@megamokusalvin3306]

The strength and the direction of the magnetic field will change.

[@radtech21]

I wish I was onboard one of them. Awesome....Awesome to the MAX.

[@pipercub123456]

As was the Apollo program..the 60's and 70's were difinitely the height of the space age..todays technology cann't even get men out of low Earth orbit....so some respect for an era passed...

[@munafmusani6767]

I can not believe they are so far out!

[@ScuddyGuitarsThings]

Am I correct in assuming that the Voyagers are too low on juice to take another Family Portrait set of photos?

[@Milchmann2]

thanks for this wonderful video!

[@sidewaysfcs0718]

@nhsplayer07 as the lady said it will take 40.000 years for voyager to reach the nearest star Alpha Centauri , ....imagine how long it would take for it to reach a star that has an orbiting planet with intelligent life on it. also the math picture is brilliant

[@TheRobloxiaStudio]

Awww poor voyager it must be tired :(((

[@raz123456789aa]

umm both voyager 2 and 1 will lose signal with us once it exits the solar system sadly

[@CRTLALTBACKSPACE]

Godspeed Voyager 1,2

[@Leonefan]

Did anyone else crack up when they heard 'only probe to reach uranus'? Just the childish side of me coming up there. Great video, NASA. I hope one day an alien race finds Voyager2 and learns about a civilization that existed millions of years ago.

[@Dyslexic-Artist-Theory-on-Time]

Interesting video! This is an invitation to see a theory on the physics of light and time! Based on just one equation (E= ˠ M˳C²)∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. The brackets represent the boundary condition of the ref-frame within infinity

[@dario9493]

well said, and just for the record I wasn't preaching.

[@Lexandreos]

Well, even if the probes take too long to reach another solar system, there's always a chance that they could be picked up by an alien spaceship. "Expect the unexpected".

[@Flipstylee6]

"90 minutes of the worlds greatest music"... if just 3 minutes of that music consists of michael bolton we have failed in epic proportion.

[@porridgeandprunes]

Whats wrong with the sound? Its very jerky.

[@KeeganGA]

by the time it reaches HD would be out dated

[@1GHOUL1]

I mean Gliese 581. XD 7x the size of Earth. 20 light years away from Earth. One of the voyagers are on its way to that planet. ;)

[@WinginWolf]

It's a shame the lifespan of the voyager probes couldn't be another fifty years. Who knows how much more information NASA could retrieve from the probes in interstellar space should they last longer.

[@GalacticMarine2012]

This is what gives me hope for the human race.

[@mottomike7]

@MWGrossmann It doesn't give it justice to the sheer scale of what has been achieved.

[@DavidLPeavy]

Great video..............!!!

[@Riotboy1]

I wonder if Voyager 1 will reach The Great Attractor before the Milky Way Galaxy? Too bad there's not a digital camera on the spacecraft to relay pictures back to Earth.

[@tstamper67]

Stephen Hawking warned against sending these "beacons" into deep space. When you're potentially the smallest creature in an incredibally vast jungle, it's not wise to call out..

[@RussellFSho]

@madmaniakid Do you know how empty space is? That is a tiny possibility

[@adastraperaspera99]

mind-blowing is certainly true

[@nuada2000]

@Yeebok What are you talking about? She sounds fine to me.

[@NibblerVStheBrain]

@wildcard418 why wouldn't we just send new probes altogether?

[@thesourceholder]

I wish I could give multiple thumbs up.

[@propergeezer]

isnt it likely, seeing these things are going so fast, eventualy they are gonna hit some dust or rock or something out in space and just get ripped to bits. infact im suprised they atre stil going.

[@GreenPartyHat]

Good Video

[@CoriganBC]

Shouldn't your profile pic be a drone?

[@Zbyszkoz]

next time please send probe to The Milk Way whit HD TV camera.

[@kelvinchewjw]

so how long does the voyager design to last?

[@zndibsi]

Great feat using 70s technology.

[@CcanCcaglar]

@mango6089 i know right! i just want the aliens to holla

[@Rayofficial13565]

@Triad72 Agreed. Poor production values. Sad that the world's foremost space agency takes a back seat to Rebecca Black.

[@captlightyear]

Futurama: "Urectum is the name the planet Uranus was changed to in 2620 to avoid people making the "your anus" joke."

[@imoj3925]

the probe shouldnt have gone slingshot style, it should have have gangnam style, wouldv gone faster

[@fjbutch]

Good vid,,,,

[@KoeSeer]

and a man who was born from a virgin foretold by humans with wings is a fact.

[@NUNCAELAMOR]

i love nasa

[@THEstrangecommenter1]

In the end, science is knowledge about everything. Even religion.

[@togos56]

Next time send the script to me and I'll read it in a less annoying way.

[@regmeplease]

Please, choose a different speaker. This one is barely understandable!

[@capenati]

or make contact with alien radio waves

[@TheGamersLegion1]

so is yours

[@1GHOUL1]

Soon one of those probes will reach the planet called Gaza(I think it's spelled that way). Gaza is a planet like Earth but it is really far away. That planet will be used before our sun explodes. We will have great technologies by then that can go extremely fast.

[@libraryquiet]

Who's to say we're the smallest creature. Shame on you Mr. Hawking, never assume.

[@westkid2860]

wow...

[@7mstf7]

nice

[@MrcFn872]

Epect the Unexpected Quotes NASA, Voyager probe will be leaving the solar system in a few years, and now its far enough away it can't see the sun. Possibly, it will take 40,000 years to reach the nearest star and the analogies are many. Now as ambassadors, it will go as no man has gone before- searching for stars systems and possibilities of life on other stars

[@LazarusDubois]

Is this a bedtime story or something? Why is she reading this to us like we're 6-year-olds?

[@Kleeeenex1]

you mean a "starcraft"

[@fufula]

@kenfo0 The irony of a person of _faith_ desperately clinging to the argument that scientific discoveries concerning evolution are false due to scarce amounts of evidence will never cease to entertain me. Carry on, you're a great source of amusement.

[@katara314]

Keep it to yourself, people should be able to believe what they want to believe. Plus, how does that relate to this video?!

[@BuddhaMUD]

@tpaulikas happened by accident? what?

[@Megadedly]

@MarsFKA Who says we won't be in space by then? or moved colonies on other planets...

[@KoeSeer]

got to be thinking, is this a good idea to gives our position to i-don't-know-what-the-hell-is-out-there? it's like giving our address completed with our property photos in a bottle and throw it at sea.

[@Leonefan]

@AgrivatedKillah Yea, but it's close. :D

[@EricGentile]

damn klingons shot it down......grrrrr.....

[@toyotaprius79]

I was disappointed when she pronounced Uranus ''Urineus''.

[@Direwolf56]

These types of comments are just as annoying as the "get saved or go to hell ones".

[@SueAapro1]

Yes, scientists figure how things work, but they did not make the working things, such as trees, animals, planets, etc. The question is: Where did the initial “trinity” of space, mass, and energy come from? In my opinion, the creator of this all persuasive trinity is the “God” that is mentioned in the Bible.
