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.

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.

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.

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.

[@Kelnx]

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.

​@@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.)

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.

[@Acklon]

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

[@TheRedRobin96]

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]

I hope we launch some purpose-built deep space probes. Something optimized for exploring the oort cloud and beyond.

[@Acklon]

@@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

[@PsRohrbaugh]

@@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.

[@Acklon]

@@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

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

[@EvonneSol]

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.

[@lizardspoint]

Hi Greetings from Nottingham England, I was 11 years old when they set foot on the moon and found it fantastic xx

[@OIllllO]

@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.

[@ezrathacker8030]

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!

[@LloydChristmas-e2g]

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.

[@robertfindley921]

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!

[@sharonbraselton3135]

Yes it wss

[@zwilnik]

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.

[@pauls5745]

I remember by about '79 everyone was so excited by the Voyager program, you were inspired to get into more space and sciencey things.

[@rodicapepescu4599]

[@JK_Clark]

An excellent piece of work, isn't it? So much knowledge provided in such a digestible way.

[@greatsilentwatcher]

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.

[@JorgeGetierr]

Really appreciate your update on the voyager 1 and 2. Simply remarkable information to be shared with humanity.

[@tjmcguire9417]

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.

[@truman42746]

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 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'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.

[@tiffanymarie9750]

One of my favorite parts of the expanse books is the constant reminder that space ...is too damn big.

[@anarex0929]

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.

[@andreagriffiths3512]

Absolutely fascinating! The Voyager twins are only a few years younger than me. They’ve gone so far and seen so much, a part of me is awed and another is saddened that we are ‘littering’ places that never ought to know of us. It’s like plastic being found at the bottom of the Mariana Trench: awe and dismay, like oil and water. But still, the fact that they are still clogging on is a testament to the engineering that went into them. They are a credit to their creators and humanity as a whole.
