""My battery is low and it's getting dark."" ~ Opportunity on June 10, 2018 Imagine the entire world fall into mourning when one of the Voyagers share its last words... By the way, NASA did send a replay to this little rover: "I'll find you in the morning sun And when the night is new I'll be looking at the moon But I'll be seeing you"
Some people think it's silly to have emotions for inanimate objects. But those objects are the manifestation of the hopes and dreams of countless human minds and hands, and they do deserve respect.
That is because they don't exist. Nothing works at near absolute zero....nothing. If you think NASA was able to circumvent physics, you would be wrong. NASA did not create, in 1977, electronics that function in interstellar space at -460 F. LOL
We could make all tech that reliable and long lasting, but charging a grand per phone every 1-5 years is a higher priority for capitalism than losing the constant profit from planned obsolescence. Soviet hair dryers and fridges are still functional today. I've had 3 fridges replaced in the same month. Now how different is the 2019 Toyota Corolla compared to the latest? Nothing major, they both go on the same roads, and aren't expected to be bought second hand due to a crippling corner of the market and dying repair maintenance corner in many cities due to proprietary parts. Capitalism raised US into poverty. We have solved all of these problems and have been sold bandaids when we need stitches.
I so admire the Voyagers. They have less computer power than our cell phones. I think they are one of the greatest successes of the whole Space program.
The hole thing is a big made up conspiracey made up by nasa and the goverment to fool the Russians in to thinking that the USA and the British are more powerful than what they really are, I live in New York and I know loads of scientists and people like that on UA-cam and my uncle works for a big bank in the city and even he agrees it’s all a big hoxe, don’t believe everything that these people tell you none of this stuff happened they have never even been on the moon and their are pictures that prove this, how can the wind blow a flag on a moon ????
@HAL-9000x Do we know that now or are we just seeing prototype teething troubles?. I just googled Boeing hib. I assumed you were referring to the helium leaks on the macine now parked at the ISS, but all I found was a visa class. ;)
@@Official-Comments That's what happens when you do not hire based on meritocracy. Trust me when I tell you that Boeing will soon suffer a serious catastrophic failure due to its internal political environment.
My Dad built the RTGs that the Voyagers, the first Mars lander mission, a Venus mission and a Jupiter mission used. The side effects killed him before the Voyagers got to the heliosphere. Other very clever people also built parts of space craft knowing it would shorten their lives. Please consider their sacrifice and appreciate their work.
I would like to imagine your father watching on as his work pays more than 10 times the reward he expected when he made his sacrifice. We all owe him, and you, a debt of gratitude we can never repay. "You should be proud" feels wholly inadequate.
1977: NASA launches voyager to space that we can still communicate with it. Some 15 billion miles away this day, some 47 years later. Yet, for some reason, my ISP still can't give me a reliable internet connection.
@@lamajsmoovesartisticmultiv2355 Got to say thinking on scale to universe nothing any human and all humans together as species in time has really been much more, than a blip. Plus voyager is probably the pinnacle, everything else will be gone as if we as species never existed in a few billion years.
I admit, I am old enough to remember 8-Track Tapes. I am older than both Voyagers too. I was born just before the first Moon Landing. So I truly appreciate and am awed by the Voyager's still being alive as it were. A testament to Humans thirst for knowledge and capacity to create things to gather that knowledge.
Also an incredible display of what real engineering could create all those decades ago. Just imagine what they'd be able to build with modern knowledge & technology nowadays!
@@nanoUSBx If only we didn’t have the current crop of geniuses running our governments. Logic would dictate sending out new upgraded probes every 15 years, using the latest technology of the time. Camera and communication tech alone has progressed leaps and bounds since 1977.
Mom worked for a company that built the circuit boards for Voyager, Apollo and the shuttles before computers were installed. Like to think something her hand touched and built is still working out there!
Born in '74, I was a child absolutely fascinated by their discoveries. I so miss watching Carl Sagan on PBS Nova shows... Thank you, Astrum. You're helping carry forward a legacy of exploration to new generations :)
I remember reading about the number of moons of Jupiter and Saturn in books I borrowed from the library. Then the Voyagers visited them and I could read in the newspapers that my knowledge was outdated.
I remember my browser homepage was set to the NASA voyager tracker for YEARS. It was something my father and I bonded on, and those two missions started a lifelong interest in our solar system and eventually space
That is so cool ! I know Jon Lomberg, who has designed the golden disc of Voyager. He is my fb friend & talks with me. Such inspiring actually. I love Voyager & I think its the only spacecraft which is so epic.
It should be noted that Dr. Ed Stone, project scientist for the Voyager project, passed away in June of this year. Since 1972 Ed and Voyager were almost indistinguishable. As project scientist he oversaw design, development, and implementation of the incredibly effective scientific instruments on board the two craft, and was the perfect complement to the brilliant engineers who designed and built Voyager 1 and Voyager 2. He was also the face of the Voyagers when communicating with both the public and with Washington politicians (to secure funding). Ed previously served as chair of the Division of Physics, Mathematics, and Astronomy at Cal Tech, and Director of JPL. Even with his numerous accomplishments, many have commented that while Ed was always the smartest man in the room, he was also the most humble. This is true. Ed and the Voyagers lived their lives together; it is perhaps fitting that their lights dimmed together. He will be missed.
I don't know if anyone has mentioned this before but your voice, articulation and tone combined with your delivery of voice over for these videos is just perfect. There's a warmth and kindness that is really inviting and it really translates your obvious awe and wonder for space exploration. There are lots of space channels on UA-cam but Astrum is by far my favourite because you can tell its passion that drives it, not any other ulterior motive.
Your commentary about all the aspects of astronomical physics as well as the amazing animation, photography, and graphics have opened a new feeling of wonder and awe in the place where we live called Earth. Thanks for making the universe more understandable for we who now have more information about what a beautiful and magical planet we live on.
I was in the womb when these launched. Being a kid, and seeing these photos on tv and on the cover of a newspaper were awe inspiring to me. It was the start of my love affair with astronomy and cosmology.
Among all the mind blowing things about the Voyagers is that a the wattage of a refrigerator light bulb can still send a signal to us from billions of miles away.
@@londonhodnet4079 How would massive corporations dominate and eat your hard earned $$ if there is so much disruption in the markets to force dramatic change? It's best for them to slow innovation any way they can.
Something which isn't mentioned here concerning Neptune's visualisation/depiction in this video is the fact that images of Neptune which were released by NASA were colour-tweaked in order to show atmospheric system details, by rendering the planet in a much deeper blue colour than it actually is. In reality, Neptune is practically the same colour as its twin gas giant, Uranus. They are both a frosty aqua or cyan colour, and are practically visually indistinguishable from each other.
He also referred to them as Gas Giants, when in reality they are Ice Giants. The funny thing about that is when the Voyager craft both launched in 1977, Neptune and Uranus were technically considered gas giants even though scientists had already questioned using that term for years since they were so different from Jupiter and Saturn. A year after the launches the two planets were officially referred to as ice giants in a paper and have been ever since.
@@Kelnxa distinction that makes no sense to me since they are both still very large planets comprised mostly of gas... What else is a gas giant other than that?
@@Mika-ph6ku An ice giant IS basically a gas giant, just with different dynamics. An ice giant, like a gas giant, is comprised largely of hydrogen and helium, but they are always super cold in temperature because they are unaffected by the heat of a star, which is not the case with gas giants. An ice giant will also have a large presence of other element/compounds (like carbon, methane, water, ammonia, etc) that will freeze and create a... crust, figuratively speaking, of dense, cold cloud strata that locks in a super hot, super dense strata of gas/fluid around a rocky core (it's all hot down there because of the compression seal caused by the cold upper strata.)
I am in awe that the same humans that can achieve this kind of greatness are the same kind of humans that will eventually destroy our Earth. I absolutely broke down into tears hearing the quote from Carl Sagan. Words like that are as moving as words from any poet, songwriter, or speechwriter ever to walk this Earth.
@@BadHorsie1I think they mean humans will make earth uninhabitable for our species. Earth will still be here, we certainly won’t. Either by our own doing or by outside factors like a meteorological event.
I am older than the Voyager probes - even listened to the radio signals from Sputnik 1. Your channel really keeps my enthusiasm in keeping up to date. This particular supercut is tremendous and as usual, your commentary is a pleasure to hear in this time of horribly edited AI commentaries. Your personalisation of the probes is so fitting!
@@itsmeagain7825 I did not even get to see the moon landing! I started reading the newspaper when the Space Shuttle was gettng ready for its first launch. I remember the TV news reporting about the Voyagers visiting our planets. When I was small a kid in the neighborhood (whose father was American) once boasted to me that his father had walked on the moon. Of course I did not believe him, but when I later asked my mother to confirm that no human had ever walked on the moon, she had some surprising news for me 🙂
I am 82 yrs old and watched Sputnik as it flew over our city. Just a tiny spot of light. Now I go outside to watch the ISS - a bright star - when it flies over. I am still in awe of man's achievements and the daring do of those who now fly in our spacecrafts. B🦘😲
The first sentence "the cosmos is within us" of his famous quote "The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself." adorns the plaque on my mothers final resting place under a young chestnut tree.
Carl Sagan was an American astronomer, planetary scientist, and science communicator. His best known scientific contribution is his research on the possibility of extraterrestrial life. He assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, which were universal messages.
That was spellbinding.. and amazing.. It clarified the problems that the Voyagers have been having recently, and it was the best overview of the whole mission I've ever seen. Thank you!
Thank you so much for turning back my clock to the beginning of the Voyager journeys. I'm 77 now qnd I remember choking up as I watched the Grand Tour series on PBS! I have kept up with the Voyagers' discoveries throughout their incredible journeys. I still remain awestruck!
Your simulations show the voyagers with their dishes pointing away from earth even though your commentary says they always point toward earth for communications. I was one of the technicians at Oxford Falls Intelsat Earth station in Sydney responsible for maintaining the data link between Parkes Deep Space Earth Station and JPL during the Neptune fly-by. I remember watching real time reconstruction of the raw data into pictures and data direct from JPL and the hourly news conferences transmitted back to Parkes, seeing each picture build up line by line as it was processed.
My father designed the integrated circuit boards that went into Voyager 1 and 2. He was still alive when they announced that V1 would be leaving the solar system. He went on to work for private first to help develop manufacturing techniques that could mass produce them and be used in consumer electronics. He was quite often a righteous prick, but he was a fucking smart one.
- isn't it interesting how even the most self righteous pricks turn out to be insignificant in the scheme of things ? Good on your father for his work and intellect though. 😀
That's beyond impressive! I thank your Father, as he must have been a truly & singularly amazing & brilliant Man! You are among the proudest of children to have walked out 'Small Blue Dot', I'm sure! Thank you, sincerely, for the, what I have to assume were many, sacrifices you & your family must have made throughout the years. Sacrifices made in order to assist all of Humankind & vastly expand the entire Human Race's understanding & knowledge of the things life itself is made of. Truly. I hope you are as proud as I think you must be to have had the Father you did.
Devices with computers on board inferior to the microchip in any of your kitchen appliances, but sending information billions of kilometers back to earth - that is just astonishing. I was eleven years old when Voyager 1 and 2 were sent off, and I was amazed time and again by the photos of the outer planets and some of their moons that they gave us over the course of the years. And, as it seams, our still limited knowledge about space has been both broadened and deepened, overturning a number of scientific assumptions and theories. Money well spent, NASA! And thank you to the Astrum team for this very informative video!
Amazed by the foresight of those who planned the mission and all those experts who built and integrated the components that lasted more than 50 years through rough weather and cosmic cloud ! Excellent presentation !!
Keep doing honest science reviews, and honest documentaries. It's the only reason I keep listening to your videos. Too many sensationalist youtube videos pushing nonsense are out there for click-bait. Just keep being honest, decent and I'll keep watching :)
"A house/planet divided by tribal Gods will never stand." Jesus When you see the trees turning green due to rising CO2 levels from Earth's increasing AXIAL TILT magnetic north you know you are at the door. Knock & Jesus will let you in. Jesus is the Way Truth & Life as Christ is not divided.
@@GregoryJByrne ... it still cracks me up how the so-called 'believers' of Global Warming can go on blissfully ignoring how much better the planet was doing when there was much more CO2 in the atmosphere. It's all in their worship of one of the tribal gods - $$$$$
Born in 1943, I was a shocked teen when Sputnik-1 was launched. I watched in awe all that followed. I'm still here being amazed at what was done with so little by the incredibly bright individuals that formed the teams that made all this possible.
Then, as politics became more liberal and the fools in the social media began trying to shape the future, all that wonderful invention and progress stopped. Remember all the fantastic inventions and progress of the late 50's and throughout the 60's. Everything from air conditioning and color TV to space flights, moon landings and SST's that went from the US to Europe in just over an hour and a half. Now, it is all gone, like NASA itself. Now, we worry about nonsense. Progress of the Golden Era has ceased.
Born in 1946 Imagine my good fortune to live next door to and be in the same science class with one of those amazing people - Wayne (the brain) Rosing.
Geez! Back in 1999 I watched The Matrix and thought it was "strange" that they decided to claim the simultaion was of the 80s, being the best of times. Now, I see with melancholy how visionary that turned out to be, the 70s and 80s were indeed the pinacle of our society: The ambitious nature of our explorations, the sheer ingenuity going into every endevour, that long-lost innocence of believing by default that anyone we came into contact was acting on the best, most ethical way for them. We need to recover that sentiment. We need to start dreaming again of a real better society, we need to look out into the bigger picture as we used to.
"our models were wrong" It's awesome that we can keep learning if we're humble enough to acknowledge that we don't already know everything and what we know now is only based on the information we have today. I look up to people who acknowledge that instead of saying "we know". Instead I like to hear "this is what we believe based on what we know".
I have to say, I'm very impressed. This video has taught me more than even "How the Universe Works" did about the edge of the heliosphere/etc. Thank you!
I was there, watching the take off of both of these probes. It was an exciting time. It seemed like we could do anything. The data that kept coming back, year after year was spectacular. It inspired me to go into science It was the first time I actually felt hope for humanity. Now as they slowly near the end of their lives, I feel very fortunate for being one of the people to be part of this great adventure. There still lingers, a thread of that hope.
Please see my comments just above for the THANKS I have forwarded to all the Scientists (now you too) as well as the Voyage r-1 and 2 for launching these adorable projects the outcome of which more than expected and still pouring down from the Sky... Bravo!
To me, Astrum IS PROBABLY THE BEST DOCUMENTARY. YOUR VOICE IS CALM AND EASY TO UNDERSTARND, the special effects are great. and above all, I feel that a human being is talking to me. NOT AI.
@@camielkotte In early 2023, I was still awaiting eye surgery to remove and replace two severe cataracts... It wasn't til after 6th June and 1st Sept '23 that I could _start_ to see again, and prior to those dates, my comments were either with full cap locks or _literally_ full of near nonsensical typos. Not everyone has perfect eyesight and, following my own experience, I have a greater understanding and patience for such comments typed in upper case ...or full of typed errors. Hopefully _you_ won't have to endure such visual difficulties, but if you ever do, I hope you'll recall your criticisms of those who _cannot see_ to type correctly. Admittedly, not all such comments may be due to poor sight, but for those who do, a little empathy would not go amiss.
The combination of the words spoken that represents what humanity is all about with the music in the background really hit hard as well. If I could describe the last 2 minutes of the video, I would just say: perfect.
Really shows how empty space really is when these probes have been traveling at a ludicrous speed for decades and have yet to hit anything big enough to cause any serious damage.
Nah, they're only moving like 15-17 km/s. Light speed is like 300,000 km/s. And then you still have to go up to Ridiculous Speed before reaching Ludicrous Speed. Going to plaid is no joke!
@@wavion2400 million kilometers without hitting anything big and without swerving greatly. I'd say that's pretty empty. At that speed a grain of sand would cause serious damage. Even hitting 1 grain of sand every kilometer, if it only punched a hole the size of a very fine grain would have entirely worn away the spacecraft.
Yeah we should make it a tradition to send one every decade. Then when we finally make the ol warp drive we can scoop them all up and put them in the museum of veteran satellites😆
I had am Astronomy Professor in college in New Jersey who worked on the Voyager 2 project. This was 30 years ago. He told me then Voyager was still sending information back to NASA and NASA was years, more than 10 years behind in deciphering them... how tragic
There will be a similar somber day, like When Opportunity went offline, when 1 or both Voyagers will go offline for the final time. I hope we have some different but equally ambitious project in the pipeline before then. Maybe we will stay mostly focused on Mars, Europa and Titan with multiplanetary goals in mind in the near future. Here's to the future either way
I was thinking the same thing. What will be the last transmission that we receive from the Voyager probes? Something like "My power is low, I am still oriented towards Ea....."? I know that the probes don't talk like that, in actuality it's a series of code but everyone likes a bit of artistic liberty for dramatic effect.
@@PsRohrbaugh only problem with that is speed. The oort cloud is HUGE and takes 100s of years to cross. Anything designed for that would need nuclear or high yield ion propulsion
@@Acklon it wouldn't get there overnight, that's for sure. But between shrinking the spacecraft, launching with high speeds, gravity assist, and things like ion thrusters, we might have a chance on the scale of human lifetimes. Look what we were able to do with new horizons.
@@PsRohrbaugh True, But I do think we are at a disadvantage now that we will have to rely on ingenuity and tech improvement rather than the Grand Tour alignment. I'm hopeful, but I know that it will be very difficult
Wow, it was quite an unbelievable segment of information, so meticulously compiled and artistically presented that now I feel it my good luck that I accidently came across it, activated it and seen and heard every single part and second of it-- it was, in fact, an eye opener as far our Solar system and it's intricate processes are concerned. In this regard, I feel it due to whole heartedly THANK the inanimate Voyager-1 and Voyager-2 and all Scientists and their teams who have had contemplated, developed and launched such a commendable projects back in 1977...Bravo! THANKS once again to you all.
NASA tried to recapture the hype around the Apollo Program with Voyager and Viking. They managed to project some of the same magic, at least to this 11 year old.
I do think that Carl Sagan's pronouncement on the "pale blue dot", needs to be emblazoned at every school's entrance, anywhere on this planet, in as many languages as necessary. and a few other places as well.
There's a band called Nightwish who, in their later versions of their song called "The Greatest Show on Earth" used Sagan's recording of that. Very moving.
that was a great video i wouldnt have thought a probe could last that long in space. what caught me was the pictures of the planets way back then today you can see it better.
Thank you. Lovely done Mr. McColgan. (Hope I spelled that properly.) I watched the liftoff of both Voyagers. Live. I knew then it was the best project ever initated by man. Yes. Man. To see them still operational is a joy. I can gauge my life by them and to see them still doing great science? WOW. Never invalidate your elders.
I am amazed at the quality of this video. I really appreciate the detail, historical information, but also the way you have strung together many really interesting scientific concepts by focusing on the identities of each of these planets. Thank you.
My dad was a child when people set foot on the moon for the first time, it's his earliest memory. So for me, growing up with these stories, it's been a remarkable inspiration for the kind of life I want to lead and the memories I leave behind for others. We're incredibly lucky to be alive at a time where we're starting to get a clear view of the night sky and just what's out there. Thank you for making these videos.
@EvonneSol If there is anything out there for their sake I hope we humans don't find them. Look what we have done to this planet. We don't need to ruin another one.
Great presentation and discovery of the blue dot and all of us from a new perspective... This invites great appreciation of the fact of our existence in the vastness of Creation🤩 A truly inspiring pursuit of our Being that every Nation and School can and should embrace to pass on to our youth to Create with to Infinity and beyond🤩
I have a hot tub from the early 90’s, still working after having most of its parts replaced, including the cpu brain. It’s had a nice run but I doubt it will ever reach the spa equivalent of the heliosphere, much less the ort cloud. My hat is eternally off to the engineers of these craft. They are the best and brightest of us to have created such infernally resilient machines.
I remember when they were launched and have always felt a little something in my heart for these little probes. They have long ago exceeded the most optimistic expectations all alone with Voyager 1 now nearly one full light day away. ❤
My father was in charge of all computers involved and the programmers and the programs and communicarions between them and those on board the Voyagers and Vikings. I was in the room when Viking landed first on Mars, and the first strip of data came in, and mankind saw our very first glimpse of the surface of Mars. There wasn't a dry eye in the room. After everyone had finally pulled themsekves together, Carl Sagan walked out to speak to the press, assembled outside.
Great video! Both spacecraft are a testament to human engineering. The tape recorders amaze me in that the tape hasn't worn out. I worked with tape recorders and it's hard to believe that they are still working. I hope both spacecraft keep working much longer.
I appreciate the factual and non-sensational way that the information is presented. Keep up the good work. By the way, we were being taught how to use IBM computer punch cards when I was in high school.
It’s amazing what qualified scientists & engineers can accomplish when the most qualified candidate is hired instead of fulfilling a quota. The Greatest Generation accomplished so much.
Many years ago I walked through the plated wire lab where they designed the memory cards for the Voyager probes. They used plated wire memory because it was much more radiation hardened. But 64K of memory was about the same size as a large hardcover novel!
Absolutely Superb, Ive watched lots of things about Voyager 1 and 2 and this has to be the most enjoyable one yet. Thanks for the amount of time it took to make this.
I really enjoyed this video and i thank you for covering the Voyager program. The information on it has been out for decades, but this is a much better format for people to learn and it was enjoyable and fascinating seeing the photos and the descriptions. Ive only recently started watching your videos but i gotta say, i love the channel and what you do. Keep on keeping on!
I think whats bittersweet and what expanded my mind as i found your channel is how insignificant we are yet on a local level there is so much suffering and the galaxy will never know or care. Shout out to all those struggling in life. Im here in the trenches with you brother and hope we all find happiness some day.
Beautiful program! I lived through these fabulous days of discovery. I remember that huge color posters of our newly discovered planets filled our college classrooms. Memorable times.
This was the most informative and interesting video I have ever seen. I am 46 years old born the year of voyager and knew so little of this. School was always boring to me and as I’ve gotten older I have enjoyed learning so much more. This video was just the kind of thing, in the tone I like. It was great sir. Thanks so much for taking the time. I will be looking forward to checking out your other stuff.
Not a scientist by any stretch but my guess on the sudden changes from Voyager 2 stem from dramatic changes in magnetism affecting it's articulation systems.
@@alexrogers777Nasa believes it was radiation that caused the malfunction, they aren’t certain of it. They identified the error and corrected it but are unsure of the direct cause, they named radiation as the best fit, but don’t claim absolute certainty that is what caused it.

Oh that was fun. I love the videos here. Explanations of stuff is always so easy to understand. I remember when voyagers were launched, but your production here taught me stuff I didn't know. Thanks.
Has anyone else pondered the massive diference in the soundness of the Voyager Probes and the Starliner, created by Boeing? Both Voyagers were build for durability despite their tiny, spindly forms. They both are running on laughable small and archaic computer equipment and programming. Yet, they are closing in on Fifty years old! And they are still moving forward, about to move into true Outer Space. Starliner tho, despite its cutting edge technology, is plagued by endless problems, especially structural issues. It's ridiculous that Boeing cannot design and craft Starliner properly, with strength, durability, and most of all, structural integrity. Let's not mention ethical integrity and Boeing at once. This is a terrible instance where the saying "They don't make them like the used to!" is so true it makes one deeply disappointed. I sure hope Boeing stops trying to cut corners, hires better machinists and experts in making capsules sound, and actually produces a worthy ship, or there will be a disaster ahead for Boeing and the entire world, and no one wants to see that, right?
I have an AWA LED clock radio manufactured in Japan at the start of the 1980s. It's been doing it thing beside my bed for 40 years without fail.. Well, I had to hack past a failing speaker capacitor with inspiration form the V'ger team, but otherwise :)
Bear in mind that Starliner is constantly in and out of atmosphere and exposed to planetary gravity. That’s rough on any system, it might be tough but it can only get punched so many times before something breaks; and every landing is basically a solid punch to everything on board. Voyager was sent into space once, and hasn’t left zero gravity since. It’s getting hammered, but not to the same degree and not by the same forces. Different builds for different tasks, and expected to withstand very different forces. Voyager probably wouldn’t survive being body-slammed onto a planet once, let alone several times. And Starliner wouldn’t be able to just keep plodding across the stars with no maintenance or oversight.
@@lord0jackostar Starliner has not had more than 4 flights, however, and has had many launches called off due to luckily discovered malfunctions and structural problems; these have been discovered on the launch pad in many cases. So, why does Starliner have so many problems, but Dragon, SpaceX's capsu;es have near perfect records? It can't be an issue within Boeing versus no such issues for SpaceX, can it?
ummmm, you're not at all realistic. There's a huge difference-- Voyagers only carried small computers and not human life or cargo and definitely not designed to return. So you like to make false comparisons because it makes you sound smart, but still rather stupid. You really haven't much a clue what you rattle on about. Starliner also has to have far more complex computer systems and unlike the little Voyager probe, it's not hidden inside another capsule. Voyager doesn't require any complex propulsion systems. People require complex life support systems that robotic probes don't need, so you only show yourself truly ignorant regarding the differences.. Boeing has been in the space business since beginning and probably as far as I was concerned, the moonbuggy was the greatest thing ever made. Bashing Boeing might be a fad or make you "cool" but it doesn't reveal much intelligence on your part. Far more fair to compare a Starliner to Man-in-a-tin can; then it's very obvious how seriously advanced the Starliner is. You're the type of person who whines when your exam gets tossed because it's full of false comparisons and nonsequitur arguments.
Boeing should simply loose their contracts, far too many lawyers and accountants with barely a handful of hamstringed engineers, there are far more competent programs, such as the Dreamchaser shuttle, far more deserving of the ludicus amount of funding Boeing burned with no viable result. SpaceX, with a fraction of the budget and a mountain more red tape made a far more reliable and reusable Dragon spacecraft and still started flying years before Boeing, it's clear the company has decayed and died, but is still being puppeteered for it's legacy by profit seeking hacks, it's a pretty insulting end all said and done. And that's without mention it's bumbling failures in aircraft...
I've been following the Voyager mission since I was a kid in the '80s. Cryovolcanoes, lakes of sulphur, and a natural "Death Star" orbiting Saturn. I remember scientists being gobsmacked at how active and varied the outer solar system turned out to be.
Thanks for uploading this complete over view of the Voyager Probes Alex it is much appreciated. I am 65 now and remember when they launched and I took notice when ever they met some miles stone or other over the years. There is a sort of melancholy to them wandering alone in interstellar space, but of course that is just me trying to anthropomorphize them.
Ya the tv show makes it sound like a trip from Saturn to mars is only a week away vs months or a year journey to the gate at 1/3 earth gravity acceleration and then flip and weeks of slowing down. Cant go faster with a mixed crew of belters and planet born. Skinnies bones would start to cave in with long 1G burns. An the juice is worse on the belters. I don't see why they can't just make it so expect mothers would stay in small cabin in a centrifuge in a base, regardless if it's on a space station, mars, moons or planetoids. And it also be beneficial for people that were injured and could save their life for surgery or recovery. When the baby's born they can just let it sleep in the centrifuge and be active 14hr at low gravity.
I grew up turning on the t v and waiting for the test patterns to disappear and daily broadcasting to begin and on these early morning adventures it was to see the latest launch of both a NASA manned space flight and in my imagination vicariously I was onboard . that curiosity and interest in space has remained with me my whole life . I enjoyed "what Voyager saw " tremendously . It is true that my interests in the universe have remained with me my whole life but my patience for waiting to see what is next has not. The 45 second commercials every 3 or 4 minutes during this video just became too much and I turned it off. But "what I saw " was nothing short of one of the grandest endeavors man has ever made . Comparable to that of putting a man on the moon . I am fortunate that I was alive to see it all . Almost all that is. Thank you.
Excellent video and commentary, thank you. I was 15 when the Voyagers were launched. The plot of Star Trek The Motion Picture is based on Voyager (Veger). Beautiful engineering. Bravo NASA/its contractors. Leaving the Ecliptic was an interesting step. 17 KM per second? Wow!
I heard a story that started with this ragtag group of salvagers who recovered a piece of what they thought was scrap metal, but it ended up being an intelligently designed construct. They brought it back to their home station to be auctioned off. The bidders for it were a varied group of aliens who ended up bidding higher and higher amounts of treasures for it until one of them ended up throwing down the "I want this and no one can afford to bid more than me" gauntlet. The Captain of the Salvage Vessel was about to say yes when, out of nowhere, an entity whom no one seemed to notice but had been there the entire time came to the fore. It shocked everyone given how ancient and legendary it was to see one of these revered beings in August this race was. This new bidder almost literally bid the heavens and the earth for this seemingly innocuous item, but if they were willing to bid so high, then to them it went. As you can imagine, the item in question was one of the Voyagers, and the big bidder was a human. By this point, we were the Ancients, and to have a piece of our past would have been a boon to have, but it was not the primary reason for this item's acquisition. The reason had to do with the probes' telemetry, plus the sensor information from the salvage ship, for you see, we had traveled so far and wide that we had forgotten our way home...and hopefully Voyager could point the way.
An absolutely superb, captivating video. I'm still amazed as ever by the utterly incredibly feats that mankind is capable of, and these two probes are a prime example. Thank you for reminding us 👍
Thank you, Alex. I wish that some record label could press the golden record in vinyl. For now, the playlist is available on Spotify. It is a really fun listen.
I still have some tapes cassettes, Betamax, and VHS that I fear would get ripped off because of age. So learning that the satellites still maintained this type of storage and uses it really baffles me
""My battery is low and it's getting dark."" ~ Opportunity on June 10, 2018
Imagine the entire world fall into mourning when one of the Voyagers share its last words...
By the way, NASA did send a replay to this little rover:
"I'll find you in the morning sun
And when the night is new
I'll be looking at the moon
But I'll be seeing you"
Someone's cutting onions in here 😢
Beautifully put. Well said
Everything I think of Opportunity, I can't help but think of Johnny 5... and then my face leaks... 😢

Some people think it's silly to have emotions for inanimate objects. But those objects are the manifestation of the hopes and dreams of countless human minds and hands, and they do deserve respect.
Computer components that can last 47 years and withstand extreme temps is just as amazing as the distance the two probes have traveled.
That’s the magic of physically large transistors - they’re robust. (Tubes rejoice!)
@@Mr.Shartly and the RTD fuel cell is just about hanging on in there!
That is because they don't exist. Nothing works at near absolute zero....nothing. If you think NASA was able to circumvent physics, you would be wrong. NASA did not create, in 1977, electronics that function in interstellar space at -460 F. LOL
We could make all tech that reliable and long lasting, but charging a grand per phone every 1-5 years is a higher priority for capitalism than losing the constant profit from planned obsolescence. Soviet hair dryers and fridges are still functional today. I've had 3 fridges replaced in the same month. Now how different is the 2019 Toyota Corolla compared to the latest? Nothing major, they both go on the same roads, and aren't expected to be bought second hand due to a crippling corner of the market and dying repair maintenance corner in many cities due to proprietary parts.
Capitalism raised US into poverty. We have solved all of these problems and have been sold bandaids when we need stitches.
And in that time I've had countless consoles, PCs and laptops that all kaput within a a few years. Amazing engineering made to last back then.
I so admire the Voyagers. They have less computer power than our cell phones. I think they are one of the greatest successes of the whole Space program.
The hole thing is a big made up conspiracey made up by nasa and the goverment to fool the Russians in to thinking that the USA and the British are more powerful than what they really are, I live in New York and I know loads of scientists and people like that on UA-cam and my uncle works for a big bank in the city and even he agrees it’s all a big hoxe, don’t believe everything that these people tell you none of this stuff happened they have never even been on the moon and their are pictures that prove this, how can the wind blow a flag on a moon ????

My Dad built the RTGs that the Voyagers, the first Mars lander mission, a Venus mission and a Jupiter mission used. The side effects killed him before the Voyagers got to the heliosphere. Other very clever people also built parts of space craft knowing it would shorten their lives. Please consider their sacrifice and appreciate their work.
God bless your Dad and all the space pioneers who sacrificed and devoted. I fell in love with Voyagers at age 10 with the Jupiter encounters.

1977: NASA launches voyager to space that we can still communicate with it. Some 15 billion miles away this day, some 47 years later. Yet, for some reason, my ISP still can't give me a reliable internet connection.

Got to say thinking on scale to universe nothing any human and all humans together as species in time has really been much more, than a blip. Plus voyager is probably the pinnacle, everything else will be gone as if we as species never existed in a few billion years.
@@kyddshine unfortunately
I admit, I am old enough to remember 8-Track Tapes. I am older than both Voyagers too. I was born just before the first Moon Landing.
So I truly appreciate and am awed by the Voyager's still being alive as it were. A testament to Humans thirst for knowledge and capacity to create things to gather that knowledge.
Also an incredible display of what real engineering could create all those decades ago. Just imagine what they'd be able to build with modern knowledge & technology nowadays!
@@nanoUSBx Well, yes, if they could simply design and build things to last anymore... Boeing [allegedly] cannot do this, somehow.

I love Carl Sagan's Cosmos (I have the DVD set) and his lectures on UA-cam.
My 50th today 🎉 yaaaay . . .😢
I found my age group!
I remember reading about the number of moons of Jupiter and Saturn in books I borrowed from the library. Then the Voyagers visited them and I could read in the newspapers that my knowledge was outdated.
@@JoeySchmidt74 Congrats!
I remember my browser homepage was set to the NASA voyager tracker for YEARS. It was something my father and I bonded on, and those two missions started a lifelong interest in our solar system and eventually space
That is so cool ! I know Jon Lomberg, who has designed the golden disc of Voyager. He is my fb friend & talks with me. Such inspiring actually. I love Voyager & I think its the only spacecraft which is so epic.
It should be noted that Dr. Ed Stone, project scientist for the Voyager project, passed away in June of this year. Since 1972 Ed and Voyager were almost indistinguishable. As project scientist he oversaw design, development, and implementation of the incredibly effective scientific instruments on board the two craft, and was the perfect complement to the brilliant engineers who designed and built Voyager 1 and Voyager 2. He was also the face of the Voyagers when communicating with both the public and with Washington politicians (to secure funding). Ed previously served as chair of the Division of Physics, Mathematics, and Astronomy at Cal Tech, and Director of JPL. Even with his numerous accomplishments, many have commented that while Ed was always the smartest man in the room, he was also the most humble. This is true. Ed and the Voyagers lived their lives together; it is perhaps fitting that their lights dimmed together. He will be missed.
@@bunbun3000 This is a sweet and very moving tribute. Honor to these spectacular achievements and those who made the dreams a reality
I don't know if anyone has mentioned this before but your voice, articulation and tone combined with your delivery of voice over for these videos is just perfect. There's a warmth and kindness that is really inviting and it really translates your obvious awe and wonder for space exploration. There are lots of space channels on UA-cam but Astrum is by far my favourite because you can tell its passion that drives it, not any other ulterior motive.

Thanks for making the universe more understandable for we who now have more information about what a beautiful and magical planet we live on.

Something which isn't mentioned here concerning Neptune's visualisation/depiction in this video is the fact that images of Neptune which were released by NASA were colour-tweaked in order to show atmospheric system details, by rendering the planet in a much deeper blue colour than it actually is. In reality, Neptune is practically the same colour as its twin gas giant, Uranus. They are both a frosty aqua or cyan colour, and are practically visually indistinguishable from each other.
He also referred to them as Gas Giants, when in reality they are Ice Giants. The funny thing about that is when the Voyager craft both launched in 1977, Neptune and Uranus were technically considered gas giants even though scientists had already questioned using that term for years since they were so different from Jupiter and Saturn. A year after the launches the two planets were officially referred to as ice giants in a paper and have been ever since.
@@Kelnxa distinction that makes no sense to me since they are both still very large planets comprised mostly of gas... What else is a gas giant other than that?
@@Mika-ph6ku An ice giant IS basically a gas giant, just with different dynamics. An ice giant, like a gas giant, is comprised largely of hydrogen and helium, but they are always super cold in temperature because they are unaffected by the heat of a star, which is not the case with gas giants.
An ice giant will also have a large presence of other element/compounds (like carbon, methane, water, ammonia, etc) that will freeze and create a... crust, figuratively speaking, of dense, cold cloud strata that locks in a super hot, super dense strata of gas/fluid around a rocky core (it's all hot down there because of the compression seal caused by the cold upper strata.)
This has been addressed in a short video some time ago, maybe 2 months?

I am in awe that the same humans that can achieve this kind of greatness are the same kind of humans that will eventually destroy our Earth. I absolutely broke down into tears hearing the quote from Carl Sagan. Words like that are as moving as words from any poet, songwriter, or speechwriter ever to walk this Earth.

This particular supercut is tremendous and as usual, your commentary is a pleasure to hear in this time of horribly edited AI commentaries. Your personalisation of the probes is so fitting!
Im not old enough, missed it by a few years, but the sputnik signal must have been fantastic to hear!
Got to see the moon landing though 👍
@@itsmeagain7825 I did not even get to see the moon landing! I started reading the newspaper when the Space Shuttle was gettng ready for its first launch. I remember the TV news reporting about the Voyagers visiting our planets.
When I was small a kid in the neighborhood (whose father was American) once boasted to me that his father had walked on the moon. Of course I did not believe him, but when I later asked my mother to confirm that no human had ever walked on the moon, she had some surprising news for me 🙂
I am 82 yrs old and watched Sputnik as it flew over our city. Just a tiny spot of light. Now I go outside to watch the ISS - a bright star - when it flies over. I am still in awe of man's achievements and the daring do of those who now fly in our spacecrafts. B🦘😲

The pale blue dot speech by Sagan will never fail to bring me to tears.
agreed, there is something very deep and moving about it, makes me want to rethink priorities and what I think as problems
The first sentence "the cosmos is within us" of his famous quote "The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself." adorns the plaque on my mothers final resting place under a young chestnut tree.
That was such a beautiful and profound thing, to see our pale blue dot and realize how amazingly fortunate we are to live on this dot.
It's almost like a prayer to me. A humble soliloquy for ourselves in a vast creation.
Carl Sagan was an American astronomer, planetary scientist, and science communicator. His best known scientific contribution is his research on the possibility of extraterrestrial life. He assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, which were universal messages.
That was spellbinding.. and amazing.. It clarified the problems that the Voyagers have been having recently, and it was the best overview of the whole mission I've ever seen. Thank you!
An excellent piece of work, isn't it? So much knowledge provided in such a digestible way.
This was as gripping as any movie. What a story, what a journey! And so well told! Thank you.
Thank you so much for turning back my clock to the beginning of the Voyager journeys. I'm 77 now qnd I remember choking up as I watched the Grand Tour series on PBS! I have kept up with the Voyagers' discoveries throughout their incredible journeys. I still remain awestruck!
Your simulations show the voyagers with their dishes pointing away from earth even though your commentary says they always point toward earth for communications.
I was one of the technicians at Oxford Falls Intelsat Earth station in Sydney responsible for maintaining the data link between Parkes Deep Space Earth Station and JPL during the Neptune fly-by.
I remember watching real time reconstruction of the raw data into pictures and data direct from JPL and the hourly news conferences transmitted back to Parkes, seeing each picture build up line by line as it was processed.
My father designed the integrated circuit boards that went into Voyager 1 and 2. He was still alive when they announced that V1 would be leaving the solar system. He went on to work for private first to help develop manufacturing techniques that could mass produce them and be used in consumer electronics.
He was quite often a righteous prick, but he was a fucking smart one.

Sacrifices made in order to assist all of Humankind & vastly expand the entire Human Race's understanding & knowledge of the things life itself is made of. Truly. I hope you are as proud as I think you must be to have had the Father you did.

Awesome
Devices with computers on board inferior to the microchip in any of your kitchen appliances, but sending information billions of kilometers back to earth - that is just astonishing. I was eleven years old when Voyager 1 and 2 were sent off, and I was amazed time and again by the photos of the outer planets and some of their moons that they gave us over the course of the years. And, as it seams, our still limited knowledge about space has been both broadened and deepened, overturning a number of scientific assumptions and theories. Money well spent, NASA!
And thank you to the Astrum team for this very informative video!
Amazed by the foresight of those who planned the mission and all those experts who built and integrated the components that lasted more than 50 years through rough weather and cosmic cloud ! Excellent presentation !!

Then, as politics became more liberal and the fools in the social media began trying to shape the future, all that wonderful invention and progress stopped. Remember all the fantastic inventions and progress of the late 50's and throughout the 60's. Everything from air conditioning and color TV to space flights, moon landings and SST's that went from the US to Europe in just over an hour and a half.
Now, it is all gone, like NASA itself. Now, we worry about nonsense. Progress of the Golden Era has ceased.

Geez! Back in 1999 I watched The Matrix and thought it was "strange" that they decided to claim the simultaion was of the 80s, being the best of times. Now, I see with melancholy how visionary that turned out to be, the 70s and 80s were indeed the pinacle of our society: The ambitious nature of our explorations, the sheer ingenuity going into every endevour, that long-lost innocence of believing by default that anyone we came into contact was acting on the best, most ethical way for them.
We need to recover that sentiment. We need to start dreaming again of a real better society, we need to look out into the bigger picture as we used to.

Nah, they're only moving like 15-17 km/s. Light speed is like 300,000 km/s. And then you still have to go up to Ridiculous Speed before reaching Ludicrous Speed. Going to plaid is no joke!

I was thinking the same thing. What will be the last transmission that we receive from the Voyager probes? Something like "My power is low, I am still oriented towards Ea....."? I know that the probes don't talk like that, in actuality it's a series of code but everyone likes a bit of artistic liberty for dramatic effect.
I hope we launch some purpose-built deep space probes. Something optimized for exploring the oort cloud and beyond.
@@PsRohrbaugh only problem with that is speed. The oort cloud is HUGE and takes 100s of years to cross. Anything designed for that would need nuclear or high yield ion propulsion
@@Acklon it wouldn't get there overnight, that's for sure. But between shrinking the spacecraft, launching with high speeds, gravity assist, and things like ion thrusters, we might have a chance on the scale of human lifetimes. Look what we were able to do with new horizons.

We're incredibly lucky to be alive at a time where we're starting to get a clear view of the night sky and just what's out there. Thank you for making these videos.
Hi Greetings from Nottingham England, I was 11 years old when they set foot on the moon and found it fantastic xx
@EvonneSol
If there is anything out there for their sake I hope we humans don't find them. Look what we have done to this planet. We don't need to ruin another one.
I was in the lab next door to voyager . We celebrated with them upon launching.
Did you know Ed Stone?
@@nicholashylton6857 I am afraid I don’t remember any name. I was a lowly aide and mostly just overheard the celebration was not a part of it.
Great presentation and discovery of the blue dot and all of us from a new perspective... This invites great appreciation of the fact of our existence in the vastness of Creation🤩 A truly inspiring pursuit of our Being that every Nation and School can and should embrace to pass on to our youth to Create with to Infinity and beyond🤩
I have a hot tub from the early 90’s, still working after having most of its parts replaced, including the cpu brain. It’s had a nice run but I doubt it will ever reach the spa equivalent of the heliosphere, much less the ort cloud.
My hat is eternally off to the engineers of these craft. They are the best and brightest of us to have created such infernally resilient machines.
I remember when they were launched and have always felt a little something in my heart for these little probes. They have long ago exceeded the most optimistic expectations all alone with Voyager 1 now nearly one full light day away. ❤
My father was in charge of all computers involved and the programmers and the programs and communicarions between them and those on board the Voyagers and Vikings.
I was in the room when Viking landed first on Mars, and the first strip of data came in, and mankind saw our very first glimpse of the surface of Mars.
There wasn't a dry eye in the room.
After everyone had finally pulled themsekves together, Carl Sagan walked out to speak to the press, assembled outside.
Great video! Both spacecraft are a testament to human engineering. The tape recorders amaze me in that the tape hasn't worn out. I worked with tape recorders and it's hard to believe that they are still working. I hope both spacecraft keep working much longer.
I appreciate the factual and non-sensational way that the information is presented. Keep up the good work. By the way, we were being taught how to use IBM computer punch cards when I was in high school.
It’s amazing what qualified scientists & engineers can accomplish when the most qualified candidate is hired instead of fulfilling a quota. The Greatest Generation accomplished so much.
Many years ago I walked through the plated wire lab where they designed the memory cards for the Voyager probes. They used plated wire memory because it was much more radiation hardened. But 64K of memory was about the same size as a large hardcover novel!
Yes it wss
They are both about 1 light day away!
That's nutty!
Absolutely Superb, Ive watched lots of things about Voyager 1 and 2 and this has to be the most enjoyable one yet. Thanks for the amount of time it took to make this.
I really enjoyed this video and i thank you for covering the Voyager program. The information on it has been out for decades, but this is a much better format for people to learn and it was enjoyable and fascinating seeing the photos and the descriptions.
Ive only recently started watching your videos but i gotta say, i love the channel and what you do. Keep on keeping on!
I LOVE that you choosed a language and examples that even small children can understand! 🖤
I think whats bittersweet and what expanded my mind as i found your channel is how insignificant we are yet on a local level there is so much suffering and the galaxy will never know or care. Shout out to all those struggling in life. Im here in the trenches with you brother and hope we all find happiness some day.
I just wanted to sleep playing this in the background but 22 minutes passed and I'm hooked to the screen. 😅
That’s what happen with me too, when I started playing these sorts of videos
Absolutely the same, and now lm sharing this content with friends, then will go to sleep..
Me too
When the algorithm is algorithming too well 😭 my sleep suffers
now stop typing and sleep.😂
Beautiful program! I lived through these fabulous days of discovery. I remember that huge color posters of our newly discovered planets filled our college classrooms. Memorable times.
We are in our 70s and it is Amazing the Voyeur is still functioning and giving us knowledge of our ❤❤ Universe ‼️‼️‼️
A beautiful reminder of what our similarities are, how little we know and what we can achieve if we look beyond our own little sphere. Thank you.
Engineering you would not find possible today. What a marvel and the engineers were! Hats off to them!
Most were Nazis... Beginning with Von Braun...
This was the most informative and interesting video I have ever seen. I am 46 years old born the year of voyager and knew so little of this. School was always boring to me and as I’ve gotten older I have enjoyed learning so much more. This video was just the kind of thing, in the tone I like. It was great sir. Thanks so much for taking the time. I will be looking forward to checking out your other stuff.
Not a scientist by any stretch but my guess on the sudden changes from Voyager 2 stem from dramatic changes in magnetism affecting it's articulation systems.
He answered the question in the video, it was radiation
@@alexrogers777Nasa believes it was radiation that caused the malfunction, they aren’t certain of it. They identified the error and corrected it but are unsure of the direct cause, they named radiation as the best fit, but don’t claim absolute certainty that is what caused it.

Happy Birthday Voyager 2. You and your sister ship have been fantastic explorers. When I think of all the science returned from these two wonderful missions, I am in awe at what we can accomplish.
Even Voyager 1 couldn't detect the astronomical amount of ads in this video!!
Oh that was fun. I love the videos here. Explanations of stuff is always so easy to understand. I remember when voyagers were launched, but your production here taught me stuff I didn't know. Thanks.
I was 25 when these launched. I had no idea how amazing they would be.
I was a zit-faced teenager when they launched, a grey-bearded Engineer now. They are pretty rad!
Astrum is getting better and better. What a beautiful and amazing documentary! Thank you Alex for sharing this! ❤❤❤
Wow! Almost an hour of wonderful journey! Tnx to Alex & Team!
Thank You, Astrum & Jon McColgan, for this epic love letter to Voyager 1 & Voyager 2 💌
The absolute best documentary I have ever watched. Human Science and Engineering at its best, with a narrative to match
Has anyone else pondered the massive diference in the soundness of the Voyager Probes and the Starliner, created by Boeing?
Both Voyagers were build for durability despite their tiny, spindly forms. They both are running on laughable small and archaic computer equipment and programming. Yet, they are closing in on Fifty years old! And they are still moving forward, about to move into true Outer Space.
Starliner tho, despite its cutting edge technology, is plagued by endless problems, especially structural issues. It's ridiculous that Boeing cannot design and craft Starliner properly, with strength, durability, and most of all, structural integrity. Let's not mention ethical integrity and Boeing at once.
This is a terrible instance where the saying "They don't make them like the used to!" is so true it makes one deeply disappointed.
I sure hope Boeing stops trying to cut corners, hires better machinists and experts in making capsules sound, and actually produces a worthy ship, or there will be a disaster ahead for Boeing and the entire world, and no one wants to see that, right?
I have an AWA LED clock radio manufactured in Japan at the start of the 1980s. It's been doing it thing beside my bed for 40 years without fail.. Well, I had to hack past a failing speaker capacitor with inspiration form the V'ger team, but otherwise :)
Bear in mind that Starliner is constantly in and out of atmosphere and exposed to planetary gravity. That’s rough on any system, it might be tough but it can only get punched so many times before something breaks; and every landing is basically a solid punch to everything on board. Voyager was sent into space once, and hasn’t left zero gravity since. It’s getting hammered, but not to the same degree and not by the same forces. Different builds for different tasks, and expected to withstand very different forces. Voyager probably wouldn’t survive being body-slammed onto a planet once, let alone several times. And Starliner wouldn’t be able to just keep plodding across the stars with no maintenance or oversight.
@@lord0jackostar Starliner has not had more than 4 flights, however, and has had many launches called off due to luckily discovered malfunctions and structural problems; these have been discovered on the launch pad in many cases.
So, why does Starliner have so many problems, but Dragon, SpaceX's capsu;es have near perfect records? It can't be an issue within Boeing versus no such issues for SpaceX, can it?
ummmm, you're not at all realistic. There's a huge difference-- Voyagers only carried small computers and not human life or cargo and definitely not designed to return. So you like to make false comparisons because it makes you sound smart, but still rather stupid. You really haven't much a clue what you rattle on about. Starliner also has to have far more complex computer systems and unlike the little Voyager probe, it's not hidden inside another capsule. Voyager doesn't require any complex propulsion systems. People require complex life support systems that robotic probes don't need, so you only show yourself truly ignorant regarding the differences.. Boeing has been in the space business since beginning and probably as far as I was concerned, the moonbuggy was the greatest thing ever made. Bashing Boeing might be a fad or make you "cool" but it doesn't reveal much intelligence on your part. Far more fair to compare a Starliner to Man-in-a-tin can; then it's very obvious how seriously advanced the Starliner is. You're the type of person who whines when your exam gets tossed because it's full of false comparisons and nonsequitur arguments.
Boeing should simply loose their contracts, far too many lawyers and accountants with barely a handful of hamstringed engineers, there are far more competent programs, such as the Dreamchaser shuttle, far more deserving of the ludicus amount of funding Boeing burned with no viable result.
SpaceX, with a fraction of the budget and a mountain more red tape made a far more reliable and reusable Dragon spacecraft and still started flying years before Boeing, it's clear the company has decayed and died, but is still being puppeteered for it's legacy by profit seeking hacks, it's a pretty insulting end all said and done.
And that's without mention it's bumbling failures in aircraft...
I've been following the Voyager mission since I was a kid in the '80s. Cryovolcanoes, lakes of sulphur, and a natural "Death Star" orbiting Saturn. I remember scientists being gobsmacked at how active and varied the outer solar system turned out to be.
Really appreciate your update on the voyager 1 and 2. Simply remarkable information to be shared with humanity.
Oh my I’m older than both Voyager,s when they were launched one with the Gold Record Amazing 🤩
Answer to title starts at: 47:43
Thanks for uploading this complete over view of the Voyager Probes Alex it is much appreciated. I am 65 now and remember when they launched and I took notice when ever they met some miles stone or other over the years. There is a sort of melancholy to them wandering alone in interstellar space, but of course that is just me trying to anthropomorphize them.
One of my favorite parts of the expanse books is the constant reminder that space ...is too damn big.
Ya the tv show makes it sound like a trip from Saturn to mars is only a week away vs months or a year journey to the gate at 1/3 earth gravity acceleration and then flip and weeks of slowing down.
Cant go faster with a mixed crew of belters and planet born.
Skinnies bones would start to cave in with long 1G burns.
An the juice is worse on the belters.
I don't see why they can't just make it so expect mothers would stay in small cabin in a centrifuge in a base, regardless if it's on a space station, mars, moons or planetoids.
And it also be beneficial for people that were injured and could save their life for surgery or recovery.
When the baby's born they can just let it sleep in the centrifuge and be active 14hr at low gravity.
1:05 A manhole cover, somewhere, disagrees...
Karl Pilkington would agree
The math says that it vaporized
While it's a fun joke, the metal cap almost certainly vaporized in the explosion :/
Operation Plumbbob.
A space ship centuries from now will be traveling the stars far from the system and will be hit from a manhole cover from the 1940s.
I grew up turning on the t v and waiting for the test patterns to disappear and daily broadcasting to begin and on these early morning adventures it was to see the latest launch of both a NASA manned space flight and in my imagination vicariously I was onboard . that curiosity and interest in space has remained with me my whole life . I enjoyed "what Voyager saw " tremendously . It is true that my interests in the universe have remained with me my whole life but my patience for waiting to see what is next has not. The 45 second commercials every 3 or 4 minutes during this video just became too much and I turned it off. But "what I saw " was nothing short of one of the grandest endeavors man has ever made . Comparable to that of putting a man on the moon . I am fortunate that I was alive to see it all . Almost all that is. Thank you.
Wow, your video is filled me with awe and wander, and even made me cry in the end
Absolutely one of your best videos. Thank you.
Excellent video and commentary, thank you. I was 15 when the Voyagers were launched. The plot of Star Trek The Motion Picture is based on Voyager (Veger). Beautiful engineering. Bravo NASA/its contractors. Leaving the Ecliptic was an interesting step. 17 KM per second? Wow!

I heard a story that started with this ragtag group of salvagers who recovered a piece of what they thought was scrap metal, but it ended up being an intelligently designed construct. They brought it back to their home station to be auctioned off. The bidders for it were a varied group of aliens who ended up bidding higher and higher amounts of treasures for it until one of them ended up throwing down the "I want this and no one can afford to bid more than me" gauntlet. The Captain of the Salvage Vessel was about to say yes when, out of nowhere, an entity whom no one seemed to notice but had been there the entire time came to the fore. It shocked everyone given how ancient and legendary it was to see one of these revered beings in August this race was. This new bidder almost literally bid the heavens and the earth for this seemingly innocuous item, but if they were willing to bid so high, then to them it went. As you can imagine, the item in question was one of the Voyagers, and the big bidder was a human. By this point, we were the Ancients, and to have a piece of our past would have been a boon to have, but it was not the primary reason for this item's acquisition. The reason had to do with the probes' telemetry, plus the sensor information from the salvage ship, for you see, we had traveled so far and wide that we had forgotten our way home...and hopefully Voyager could point the way.
What? You lost me. Got a simplier version for a simple person
An absolutely superb, captivating video. I'm still amazed as ever by the utterly incredibly feats that mankind is capable of, and these two probes are a prime example. Thank you for reminding us 👍
Very cool. I recently just found your channel. I am glad I did M8, thanks for all of this.
The Earthrise photo was taken on Apollo 8 by Bill Anders.
I was wondering if anyone else noticed that small mistake.
No no nooo!
Thank you, Alex. I wish that some record label could press the golden record in vinyl. For now, the playlist is available on Spotify. It is a really fun listen.
I still have some tapes cassettes, Betamax, and VHS that I fear would get ripped off because of age. So learning that the satellites still maintained this type of storage and uses it really baffles me
