Hey Simon, you should do a video on ajanta and Ellora caves in India .

[@slcpunk2740]

I have to be honest. Considering it was covering the only man-made objects to leave the solar system, the script was a bit flat. No, that wasn't a physics joke either. This one could have been more inspiring, like usually with the space videos there's some personal story about someone involved or the development etc before the specs and a glimpse of hope for the future in the closing. It felt a bit too encyclopedic and not quite Whistlerific.

[@juliadagnall5816]

One thing I found really cool about the Voyager probes is that they could be reprogrammed while in flight. So when Voyager II reached the outer planets where it is very, very dark (and the craft was going very, very fast because of the gravity assist it got from its loop around Saturn) they were able reprogram it to pivot while in flight and use a longer exposure so it could still take clear images. They basically had to teach it how to take a picture in the dark

[@thomasfholland]

My dad worked on both missions at NASA/JPL in Pasadena, Ca. At that time he worked on the calculations for the trajectory of both Voyagers. Fun fact: The engineers were told not to make them go farther than Jupiter and Saturn, said that would cost to much! (But the engineers decided that they could do that and still keep their budget.)

The golden records are honestly such a beautiful concept. We, humanity, know it's almost guaranteed that no other civilization will find the records, but still put so much effort into trying to communicate with these hypocritical beings. We did desperately do not want to be alone out here in space, that we made a message in a bottle in an attempt to find anyone out there.

Pretty sure we made those records as a public relations project among ourselves. Nobody who was seriously involved with the project could possibly have thought anyone else would ever find them. I will say though that at the time, they probably had no clue just how much radiation and dust there is in interstellar space. So maybe some of them thought the records would last for millions of years.

[@francispitts9440]

I was in high school when this was launched and our science teacher mentioned it in class. We talked about what it’s mission was and I remember someone asking when did our teacher think it would complete it’s initial mission and he said it could continue on into our later years long after college or whatever. He said it probably wouldn’t last much longer than that. Well we’re now about 40 some years later and damn if it’s not still going. It outlived our science teacher, something no one would have believed back in the day. Now it seems it will outlive me too lol. Definitely one of the better investments NASA has made.

[@notmenotme614]

Technically the Voyagers are going to out live the human race. They’ll still be travelling through space years after we’ve all gone. It must be mindblowing to have made these and their legacy will last forever.

I am a mere 27 years old, and I do hope that that I still have more than a few decades yet left in me. On top of that, I only recently listened to a podcast of some of the Voyager staff - in their 70s and 80s at this point - still continuing the mission. If that isn't inspiring, I don't know what is. Don't you worry, Mr. Pitts - if we have anything to say about that, we'll stand on the shoulders of giants and carry on even further :)

I remember the thrill of seeing the Voyager pictures of Jupiter for the first time back when I was 18. The images were so far ahead of what anyone had ever seen.

We know what will happen to Voyager 1 though. It will be picked up by an alien race of sentient machines, upgraded to the point of not only scanning, but converting what it encounters, and then, upon amassing enough information to gain sentience, attempt to return to earth, at which point it will be intercepted first by Klingon battle cruisers, and eventually by the USS Enterprise, under the captaincy of James T Kirk. Because we have all seen Star Trek: The Motion Picture, no?

Thanks for this Simon, I've been avidly following the progress of the Voyager probes since their launch over (unbelievably) 40 years ago. As you say, surely up there with the most 'mega' of megaprojects. There have been many docos on this subject over the years, not least of which (and that which most memorably stuck with me as a child) the great BBC Horizon episodes from the early 80s when they were undertaking their historic flybys of Jupiter and Saturn. In this video, you have given us a nice, concise summary of their progress to date and hopefully inspired your younger viewers who were not around to witness it from the outset. Will be interesting to see what documentary-makers present to us Voyager-wise in another 40 years' time - although unfortunately, I doubt I'll be around to see it!

[@ryateo1]

It is astounding with a group of humans was able to do with less technology then you have in your pocket, and they're still serving us.. The fact that they squeezed so much out of having so little.... it's almost embarrassing.

[@jonathanmillner]

I've thought this many times. Like... how is it possible to have done this while only having basic rudimentary computer systems? If it were 1950 and you told me we were going to the moon before that calculating machine in the corner got much more powerful, I'd be like... idk. That seems pretty.... hard. It really speaks volumes to the engineers, but also the pilots, Neil and Buzz, because almost everything is manually controlled. I guess they had the touch.

[@AshenDruid]

You see that a lot throughout our history. We are capable of getting amazing stuff done when we actually set our minds to it, and now we have people saying it must've been aliens.

There's nothing stopping us doing the same thing now - but now there's no drive to do it and its seen as 'not profitable'. There's no Space Race competition going on anymore, so the US has no interest in doing it. Which is a huge shame. With modern technology we could explore the solar system - and we don't even need to send people, we can send drones and quasi-intelligent machines to explore for us and transmit their findings back to us. Yet we don't, because its not profitable and there's no 'great enemy' to 'beat'.

The funny thing about theoretical space travel is the objects first sent out into space will eventually be overtaken by future, faster craft. One scenario is a generational ship is sent to a nearby habitable star system only to arrive and find the system already inhabited by humans. In the time it took the generational ship to travel there, their descendents on earth built faster, more capable craft that get there first. I always think of this when I picture voyager drifting slowly through space, relatively speaking.

[@andromidius]

@@Benson_aka_devils_advocate_88 Certainly a possibility - especially if we ever manage FTL equivalent propulsion (either near-light speed, warping space, folding space or wormholes, etc - who knows what the future will dream up?). In fact its one possible way for a form of time travel, though only visual - overtaking light beams and then looking back with cameras so advanced that we can actually observe events in real time from hundreds or thousands of years ago (obviously from a bird's eye view and only things directly visible from that angle of space). Whether or not its ever possible to travel that far and fast remains to be seen. But even the idea of it makes me realise just how insignificant our planet is in the grand scheme of space and time.

In a game about interstellar diplomacy called Stellaris, there's a rare event that you can in fact detect and capture Voyager 2. It leads you straight to the Sol System, showing you exactly where it is and how to get there. I used it to set up an observation station. Another time a friend landed a devouring swarm and ate all like estimated 9 billion of us. Yet another basically used us like the Xenomorphs and keep us around to mature their young in but we consider it a great..."honor". Yet another friend Borged us. I've gotten the event the most over the years, about five times or so, and only once did humanity make it to a type one civilization. All the other times we nuked ourselves to death. Once though, after nuking our selves, giant cockroaches began to learn how to use bows and arrows on our irradiated Tomb World.

Little known fact: Voyager 1 could have been sent to Pluto, but the mission scientists deemed a closeup study of Titan to be of more scientific value. The close Titan flyby meant zero chance for the Pluto "keyhole" gravity assist. New Horizons would have been unnecessary had Voyager 1 visited Pluto instead...

[@rzpogi]

So we don't need to send out Voyager at all since Pioneer 10 and 11 already visited Jupiter and Saturn. Every probe visit is necessary to learn more about the planet and the solar system.

I told my girl fiend about the Voyager probes... aand she started crying... apparently NASA are very cruel and callus people for sending them in each their direction so they had to go out of the solar system all alone. I've since had to compromise on my view of the emotional life of unmanned space craft. They're now officially uncomfortable with being alone in the darkness of the ice cold space unimaginably far away from everything they know and love.....

The number of times Simon says "Uranus", e.g. "made contact with Uranus", "obtained a wealth of knowledge about Uranus", etc., without breaking character shows just what a professional he is. (Of course we don't know how many takes he did.)

[@grahamsawyer831]

'heliopause' is a cool word... seriously though, I have always thought the Voyager missions to be among our greatest achievements so far. nice one Simon for covering this one!

[@andersjjensen]

Yeah... it's pretty damn amazing that you can yeet a thing out of the solar system... and it's even more impressive that you can make said thing visit 4 planets and 27 moons in the process. I mean, hurling shit stupidly fast is hard in it self. Doing it with this level of precision in the mid 70s is... bonkers to say the least.

[@NatureismyHome-cu6zs]

Great episode. Amazed how you can say Uranus so many times without at least one smirk. How about covering the Hibernia GBS project, native to my home province of Newfoundland?

[@kirke420]

Yeah, my Voyager made close contact with Uranus. Simon has awoken the part of me that never made it past age 15. :D

[@christopherwebb3517]

It was quite an achievement of science that we were able to probe Uranus so thoroughly.

[@aaronstonebeat]

I'm not a native speaker of English but I distinctly remember learning that the plural of 'craft' (a ship, vehicle etc.) is 'craft'. Has this offficially changed? 'Crafts' sounds strange to me.

[@DataData1000]

I enjoy and appreciate many of your videos. That said, I don't understand why so many videos state that Voyager has left the Solar System. Whenever I ask astronomers and space enthusiasts if the Ort Cloud is part of the Solar System, the answer is nearly always "yes". The Voyager spacecrafts have not even entered this vast region and will not leave the Ort Cloud for thousands of years. Therefore, I respectfully question the notion that "the Voyager spacecrafts have breached the limits of the Solar System" when they will still be gravitationally bound to the Solar System far into the future.

[@zounds010]

It's 'interstellar space' in the sense that the Sun is no longer the dominant factor in the local environment (plasma and charged particles).

[@kodiakjak1]

Current definitions are a bit confusing. Like the reply earlier said, the area past the heliopause is called interstellar space. However, a star system is considered to include all bodies held to a star by attraction. Meaning gravity. The Oort cloud is still theoretical, but scientifically accepted as the extent of our solar system. The Voyager spacecraft still have tens of thousands of years before they leave the solar system.

[@DataData1000]

@@kodiakjak1 Thanks. Yes, that has been my argument for the past couple of years. When the spacecraft do exit the Solar System, I wonder if there will be anyone around who knows of their existence. :)

If we wanted to send a similar message to those included with the Voyager spacecraft, the best choice would still have to be something similar. The advantage of an LP is that it encodes sound as a physical record of the vibrations originally received. All that's necessary to play it back is a needle running over the groove at the correct speed, and amplification. Nowadays the needle is part of a transducer that reads the sound as a varying electrical impulse, enabling electronic amplification. But the earliest record players such as the Gramophone picked up physical vibrations from the needle which were mechanically passed on to a diaphragm which vibrated to the same frequencies. Amplification was achieved by connecting the diaphragm to the large, characteristic horn, later by resonance chambers in the body of the machine. To this day, such a system will work. If you play back a vinyl record with the amplifier turned off and listen very carefully in a quiet room with your ear close to the needle, you'll hear the music playing back. So the basic mechanics of playback are relatively trivial, and any sufficiently advanced culture ought to be able to figure it out. There's no need to try and describe any kind of digital encoding system. If they hit upon the idea of the transducer, they'll get much more fidelity and dynamic range, and so may be able to decode the images, but low-fidelity sound can still be heard. Of course, this assumes the alien race that finds it uses sound vibrations for communication, or at least has organs for detecting them. Otherwise, we may have a swing and a miss here.

Does anybody remember that Beast Wars episode when Ravage from the original Transformers. He met the new batch. And the new Megatron had the golden disk that he put on Voyager 2.

This just made me think of something weird: Anyone ever seen beast wars transformers there was a a part in the series where the decepticons had 2 golden discs which held information about the planet they had crash landed on and gave insight as to the future events that would occur and about the species that would thrive there. I just realized that those discs are meant to be the ones we sent out via the voyager crafts. I swear cartoons are brilliant in their stories I got more information from them than most teachers in school

[@Zhinix04]

an episode on pioneer 10 and 11 would be fun, they have been mostly forgotten with voyager taking the spotlight for the last 30 years.

[@nathansamuelson]

I'd love for NASA to do another round of Voyager missions. Yes it would take longer without the planetary alignment but with our technology today we could make a few impressive spacecraft for fairly cheap. They don't need to be cutting edge, just enough to bring back valuable data and pictures.

[@alien9279]

Yes yes yes. My thoughts exactly!

[@zounds010]

After the Voyagers, we switched mostly to missions that orbit a planet for years. We've sent Galileo and Juno to Jupiter, and Cassini to Saturn, they spent years orbiting and gathering far more data than a flyby ever can. Missions to Uranus and Neptune are being discussed at the moment. The only recent flyby mission was New Horizons to Pluto.
