In 1965, a PhD student figured out that every 176 years the four planets in our solar system align in such a unique way that it is possible to use their gravitational forces to slingshot from one planet to the next.
This insight, that came to fruition using just a slide rule and simple computer programs, became part of an ambitious mission to send two probes and golden records out into space for a grand tour.
Enter: The Voyagers.
The Voyager probes are two obscure looking robots, weighing roughly 800 kilograms with giant arms and big ears, it took 1,500 engineers and scientists to bring these robotic explorers to life.
The Voyagers took some of the first detailed snapshots of planets and moons-revealing Io’s volcanism, close-up details of Saturn’s icy rings, and Neptune’s great dark spot.
And after traveling for more than 43 years, clocking in 18 billion kilometers traveled, the Voyagers are taking humanity into the next great beyond: interstellar space.
With the opportunity to visit Uranus and Neptune, the NASA engineers developed a mission within a mission, outfitting the probes with 11 different instruments, redundant systems, and autonomous controls.
Find out more about the Voyager mission, what we’ve learned so far, and the experts behind it all on this episode of Focal Point.

You could have called this "The Journey of Voyager" and it would have been a fine title that hundreds of thousands would be happy to click upon
This was a fine video. But I gave it thumbs down for clickbait
@zztop3000 oh sorry Mr Smart jaja
Well I learnt about the abrupt change to the interstellar medium measured by voyager.
that's all fine, and I'm pretty stoked that this video offered some new knowledge for you folks. I liked the video quite a bit. however, it wasn't really surprising (people knew that there should be *some* big change at the heliopause) and it was just a sliver of the mission.
not having a clickbait title would give the video a lot more longetivity.
Christopher Jensen I'm inclined to let it pass. Content was good, and did in fact talk about a phenomenon at the edge of the solar system. Before there was click bait, the title would have been understood as piquing interest in real science with some mystery. Click bait leverages everyday language to trick you, and in fighting it we want to retain the everyday meaning, not to eliminate normal usage.
Surely the PhD student deserves to have his name mentioned. It's as if you were trying not to mention his name. What could he have done to be omitted like this?
Nothing really. At leas his Wikipedia article is squeaky clean.
Gary Flandro is his name. He was recognized with an EAM from NASA in 1998, though I still feel this isn't enough.
@@Blitzman364 thanks! You might really like a video im releasing on Halloween, "the actual, physical, reason why time slows at the speed of light". Stay tuned...
He / she
And since is 2019
Add pronouns below
Very misleading title. They didn't "find" anything. The satellite just hit the interstellar medium they already knew was there.
Nice thanks for the info, i was in the middle of the video
They found the start of the interstellar medium.
@@LeofromFreo yeah, but that was totally expected 😒.
Title have nothing to do with content.
I bet you guys cant guess who volunteered every time for hall monitor duty back in grade school
"just"
And what is really impressive is quality of that probe! Still working, still running!
It's last relay to us will be, "I can see nothing ... two weeks later ... It's cold ... please send new reactor cell ... goodb y ... "
"a PhD student"
How about you guys start giving credit with actual names.
maybe he was not white .
@@Q_QQ_Q high probably he was indeed given the statistics from known research on IQ of world populations. "Just sayin' dawg"
Gary Flandro is his name.
his name on 0:20

He's white and still living in his golden years.
Nice video, but disappointing due to the clickbate title: there are no new facts that have not been published for some time.
#me2
Yeah getting really sick and tired of that to be honest. I go ooh some new discovery. And then they say nothing new it's shit like this that make me so cynical nowadays.
Gonna report for misleading title
Wanted to say the same,nice clickbait...
agree, poor clickbait title to an otherwise good channel
“A Phd student discovered this”
Me: **Looks at my term paper in shame**
Wait until your older and you watch this stuff bc it's actually interesting but then realized they don't know as much as YOU want to know. Why send a disk of our beings when any other living being like us are far to big to even think about seeing anything of our nature. Think of us as the little ppl on "Horton hears a Hoo" by Dr Seuss
Cody Morkert cool theory, also im 23 im not 12
Them: Able to receive images from over 6 billion miles.

Look at the antennas
I think this is amazing, it really captures the size of space compared to the size of our life span. She started in the program when she was young amd fresh out of college and now shes an ageable person now actually seeing practical stuff about the universe. Just wish there was an easier way to pass on her passion and knowledge to the younger generations
“very empty, very dark, and very cold...” i guess space is like my soul
Can I comfort you by saying that it is not the whole truth as "empty" can not have a temperature per se.
Okay but I will honestly cry when the mission is over-
You gonna miss the computer generated photos and videos...
@@dylandylan1907 lol
Did you cry when cassini crashed into Saturn? I did
@@ujjalshill6442 yea I cried me a river.. it felt like the end of a good Netflix series of seasons that has been ended. Why they take so long with the new season's tho..
I've been waiting a long time on that soap series "we're going back to the moon" I followed it in the 60s on HippieFlix but now it's 2019 and still no new episodes..😞😪

You and the rest of these idiots are too stupid to realize that it wasn't click-bait. 😂

It's not aliens, *_until it's aliens_*
What's the newest creation of aliens now a days? Is it the moon? Moon is a spy?
"What Lies Beyond the Edge of Our Solar System?"
*Shows the entire history of two Voyager spacecrafts*
Michael Andrew Minovitch should have been awarded a Nobel prize in mathematics and physics, gravity assist Discovery and its equations are things taken for granted since back then till now.
The Voyager probes are the one of the greatest accomplishments. Building a space craft that accomplished so much with the technology available at the time is amazing. The engineering team worked out new and unheard of specifications to make it happen. It's absolutely amazing to me.
This was easily the best ever video on Voyager missions on the entire freaking planet.
I think that it is so cool that she and others worked on this right out of college and they are still there monitoring it 43 years later.
It gives me a lot of happiness when i realise that even if something wiped out the entire earth we still have left a mark on this vast universe. Humans can achieve anything!💪🏽💪🏽
Everything, except hoverboards.
boy I'm kinda glad the ETs will only know what earth was like in the 70s which was certainly a more peaceful time than 2019.
Jason K no it wasnt
@@zaphrode4110 tbf people were smarter back then
Jason K
You might possibly be right. Alot of what’s happening in 2020 than in 1977. Today (2020), there’re so much hate going on. Police shootings, injustice demanded, COVID-19, the list goes on...
All these happenings reminds me of the Billy Joel song, “We Didn’t Start the Fire 🔥”. Loved that song.
70s wasn't peaceful than 2019. It was just YOUR experience.
that woman look like Smart version of Ellen Degeneres
Ellen doesn’t look stupid or anything though.
@@Dakarai_Knight did you know she's anti critism and also best friend with war criminal?
Yeah, i don't like ellen because she doesn't seem very open to non-Ellen point of views lol
Yeah, I doubt this woman would hang out with George Bush.
@@foxnebula145 so are 1000's of other famous people, what's your point
Retired astronomy professor : Without a doubt Voyager is one of Humanity's best ever achievements!! We're long past due for a continuation of predecessors!!
I was born in 1977 and I am amazed at the distance covered and job done :o
My grandmother worked on Voyager 1! Her signature is on it and everything. I'm in awe knowing something she worked on is somewhere in space.🇺🇸
There is something misleading on your picture
@@rgerber The fact that it's taken at an angle and shrunk down to size to fit the screen? That's an awfully rude to comment to leave.
That’s pretty mind boggling! Her signature had left this solar system.
@@goldiebelle no i was simply not sure what part of that piece was clothing or hair. Actually like that clichéd black Wig type hair you see in a typical Cleopatra depiction. But it's okay to expect the worst of anything. Very optimistic 👍
@@rgerber A vague comment such as yours would solicit such a response. Especially these days. My apologies for assuming the worst. Thank you for clarifying your comment.
Fantastic video! Absolute excellence in every regard! To the ingenuity of our species.
“To everyone’s surprise, Voyager kept going.”
Seriously?
I was like "wait, how the hell were they supposed to do anything else, they weren't given the fuel to ever stop, short of lithobraking". Even continuing to function wasn't exactly a surprise, it's not like the RTG power source just stops working like a discharged battery one day.
What the Voyagers found as they transitioned into the interstellar medium was inherently unexpected because it was unknown. Even if one person or paper had nailed everything in detail in advance, it still would have been a surprise to everyone else. But _nobody_ was surprised when a spacecraft that had worked up until that point _kept on working._ It's fair to say _before launch_ and _before confirmation_ that you'd be surprised if they were still working after encountering Jupiter's radiation belts. But once the first one did survive, it got a whole lot less surprising when they failed to fail, day after day.
@@mal2ksc Lithobraking! Like, crashing into a rock?
@Why Soitanly
It's generally used to refer to hitting a planet or moon, or at least an asteroid large enough to survive the impact itself, but yes, that's usually what is meant by lithobraking.
I agree...That was a stupid thing to say. Voyager would absolutely
have to keep "going" since there aren't any parking meters that far out
in space. Duh! 😂
space is mostly empty so I don't think there was any chance of voyager 1 hitting a asteroid.
THIS IS AWESOME!!!!!! ALL HUMANITY has a pair of eyes and ears on the edge of the solar system and beyond
Got me crying. So inspiring. Thank you Suzanne Dodd.
Those satellites are 42 years old now. That's amazing.
Great episode!!! loved it.
It makes my cry everytime i see Pale blue dot image.so tiny existence and so big desires
Incredible videos on here!
Such complex and important machine wouldn't have happened without the aid of the humble and obselete *slide rule* .
It's mind-boggling to think that a person researched how to slingshot a probe in outer space.
And here I'm not able to draw a proper line on a paper. 😌
Great video! 👍🏻 Seriously. I love Voyager twins. Thank u for the video.
Imagine what the probes send 176 years later will be like?
The aliens would laugh because we still use gold and pictures ...
Gold and pictures? They would laugh at our flaw of allowing "ego" before knowledge..
I hope that the aliens will have a sense of humor, I can't wait for intergalactic comedy.
Yeah cuz that's what incredibly intelligent creatures do, laugh at those less intelligent than them.
@@BboyKeny not in this lifetime bro maybe in your next 2, 5 rebirth you might see aliens comedy.
Gotta flex on them alien bitches
Since the 70’s !!!! Wow that’s amazing
Distance of Voyager1:
So it will take 20 hours (72000 seconds) to reach the earth * speed of radiowave (299 792 458 m/s) = 2.158506e13 meters so its 21,585,056,976 km away from us, and the Heliosphere is 18 billion km away from the sun.
Correct me if I'm wrong
Any videos about voyager still excite me! Always good to hear extra info and gain perspective from someone who's worked on it since the beginning
Imagine figuring this out, at a summer job. Adults today don't know how to wear masks.. when they've been wearing one they're entire life
@Seeker give that "PhD student" a name! Cause even New Horizon mission uses his study for gravity assist to reach Pluto in time
Awesome content. Keep up...
When am I getting the opportunity to go to Uranus is what am gonna ask my girlfriend now. Thank you Seeker.
When will V'ger (ne: Voyager) return to destroy Earth?
i understod that reference! XD
The title was correct. Thanks for a well-made video. The personal stories make the video worthwhile even for those of us who know the history of these programs very well.
Imagine how cold and dark it is out there so far from the sun....
Now consider that 99.999999999% of the universe is much colder and darker than that.
Yea like how does the TEG not lose heat to the cold of space? We need that insulation for housing on earth.
The radioisotope thermo-electric generators (the power sources on both Voyager spacecraft) do lose some energy to space in the form of radiation.
However, the engineers have tried their best to provide enough padding and insulation so that the optimal amount of heat is kept inside the spacecraft without it being too heavy.
Even tho it’s cold u wouldn’t freeze quickly it’s mainly the low pressure that kills u
My sister is much colder. 🙄
Ehh, calling Space "cold" is very misleading. You know the ice is cold because it drains heat away from your body when you touch it (the cube entropy energy is much lower than tge surrounding too but its easier to understand by empirical reference xd).
Vacuum has very little particles which could drain the heat away from anything, so we consider it (-*perfect* vacuum) a perfect insulator. However, even in a perfect vacuum heat is being 'transfered' back and forth by infrared radiation. Its not a problem here on Earth because any object gets from the radiating environment roughly the same amount of radiation as it emit, but in Space it's much different.. You basically become a Space-Flare XD
It would be amazing if we built a successor to these probes. With a similar mission profile.
Truly a great 👍 mission. A lot of my enthusiasm towards the subject has been propelled because of missions like Voyager. Thanks! 🙏 . May this universe appreciate us little humaaans.
Remarkable, how tiny & fragile is our human existence. Voyager may be at or outside the edge of our own solar system which is but a small part of just one spiral arm of the Milky Way galaxy (itself containing in total a further 100-400 billion or more stars). Then there are a further 100-200 billion+ galaxies in the observable universe each containing billions or perhaps trillions of stars.
We may be infinitesimally small in our universe but we are not insignificant because we can live and see.
Plot Twist: the golden records will just be a nostalgic mixtape to the aliens who visited us at the dawn of solar system.
Awesome video. Thank you
In essence, it's like a vhs player in some old guys house that set a world record for never being unplugged, it's clock is accurately set as well!
1960s engineer: my first job was working on a rocket!
2019 engineer: tech support how may I help you!
Yet another great video.
Absolutely fascinating! Thank you. 😊
just imagine that, when long after we thought that we have already lost voyager. it came back with a guest from another star...
A similar idea is used in Grant Thompson's story--it's called "Interference".
Great video. Thanks.
I'm honestly so scared of this...
Is there a name for that phobia? A phobia of the dark, unkown and endless?
Yo that shit crazy dawg
Chills.. literally chills me guys❤️
Amazing!
Very cool stuff.
Although I understand why the sentimentality,
of those who have worked on the project, for so long;
I don't think it'll be sad, nor "the loss of the spacecraft,"
after all, it's fulfilling it's purpose, as humanity's first reach,
for interstellar space. I mean, the probability of either of them crashing,
let alone both, is very low; although I agree, that such a crash, would be sad.
If anything, I think it should be celebrated, rather than grieved,
when we lose contact with it, due to range/RTG lifespan;
as at that point, it's finally undertake it's final purpose,
the very reason, why there are messages onboard, was for this, wasn't it?
In one week: what the interstellar mission found was not what they thought...
These missions blow my mind that they’re still working and sending us new data 🙌🤓
Whoever did this video, you are a grand explainer. I love how you present this material.
The fact that their is cosmic energy and charged particles pushing on the Heliosphere worries me ALOT
Whenever I think of the Voyager probes wandering forever in the depths of space I ponder if one day it will become V'Ger returning to find it's creator.
0:19 - PHD student, who deserves some respect
Very nice video
Voyagers, designed to last for 4 years, lasted 40+. The best of American engineering, that too in the seventies.
Meanwhile my neighbor's new Chevy, had a broken door handle within a month of purchase.
We've come a long way!
Long live Voyager ☺ I'm sure it will. Maybe in the future we can catch up with it ☺
4 more years left.. after it loses its radioactive source of energy
//Orange Sky// but there's not so much to slow it down. It'll just keep on going untill some star pulls it into it system. Aliens wondering....what the heck is thst ☺
@@malcolmhardwick4258 why these smilies?😒
Abhay Agarwal felt smiley that day 😎
I read a Star Trek book about voyager, developing self awareness and coming back to earth. It was a awesome!
The only unexpected thing about this video was that everyone was surprised that the spacecraft continued their trajectory after passing the final planet. Why were they surprised, were they not aware of orbital mechanics?
It is amazing how the Voyagers are able to travel that far and that fast and not hit anything or get damage by rocks.
Think I remember a star trek voyager episode where they find this probe :)
lets all just hope that once it does stop transmitting, Voyager doesn't disappear into what we once called a "black hole".
Maybe it is the greatest space mission of all time. I heard that The Pale Blue Dot had no scientific value. It was Sagan's poetry.
Some damn bad ping there, Voyager.
Pluto was originally supposed to be part of the grand tour but because of budgetary cuts, it wouldn’t be visited until 2015
I from the heart love the Voyager Missions for them as one of the biggest achievement human kind made just for fulfilling the pure inherent curiosity.
id just like to add that the original plan wasn't just going to Jupiter and Saturn. that was all they could get the funding approved for, the original plan was many more than 2 probes visiting all the outer planets. the engineers, however were gunning for the grand tour and knew that once they got to the planets there would be a swell of interest to extend the mission. they worked their butts off to makes sure they could build probes capable of doing the grand tour on the budget of the 2 planet tours, and that work payed off in the end. without their hard work, we still wouldn't have any craft visit Neptune or Uranus. what little details we have from those planets and their moons is all from Voyager.
The so-called simple computer program graphic that you show around 28 seconds looks like it's more from the mid-80s than the 60s
How far ahead in time is the voyager probe?
Keep boldly going...
These guys are the real legends . unfortunately people don't know about them .
Today, they would definitely send some Drake Shit or Cardi Poop on the Voyager, for aliens to never search for Earth 😂😂
Why this data is 2O12?
What about 2O19 data?
.
About time for voyager 3&4
Voyager 1 is my fav probe of all time, wish we could have placed a solar sail on it, for it would be interesting to see where it could be now if it had one.
Still an impressive feat of engineering. That's what mankind can do when we act together for the good of everyone. Hopefully we can evolve into a species that learns to live in harmony while we still have a chance.
Peace and Love.
"I have seen the enemy and it is us."
Beautiful
Hello there, I am very interested to know how communications are relayed and how long does it take for them to reach us and vis-a-versa ? If you could create a video on that, that would be thrilling.
Thank you for this and all other episodes too 🙃
@zatan D We get a signal on earth from Voyager 1 in about 20 hours, one-way.
Incredible
Rip Voyager, you will be long remembered
More like this! (With less clickbait titles, please)
Anything _found_ in Space is *unexpected*
Lots of Respect for voyager 1'2 😜🤗🤗🤗🤗🤗🙏🙏🙏👍👍👍
