    @stoffls, I thought I posted my comment.🤔People can look at real-time data just search "Mission Status Voyager". IIRC V2 actually launched before V1 and V1 is some ~15 B miles (24 B km) away which even after ~46 yrs that's still just a fraction of a single light year & yet we talk about objects in our own solar system being hundreds/thousands of light years away just as we are believed to be situated around 26,000 LYs from the center of our galaxy so that's ~153 quadrillion miles (244.8 quadrillion km) and V1/V2 have only traveled about 13.5 BILLION miles (21.6 B km) avg between the two. So the center of our galaxy is about 12,000 times that or the equivalent of ~523 MILLION years away at the avg speed of those vehicles traveling ~35K-40K mph (~56K-64K km/h) We know they can use planetary gravity to "sling-shot" spacecraft to higher speeds but that also takes more time. We really need better systems of propulsion if we want to make more meaningful exploration of space both manned/unmanned. Frankly, I was a bit surprised with the talk of V1/V2 being older tech, slowly depleting power etc., that they haven't launched new probes with our more advanced tech. I know they have several spacecraft/telescopes out there and though they're reported to have seen much further than our spacecraft have been, it'd be best to actually send the physical spacecraft to investigate phenomenon up close.

    Growing up in the Cape Canaveral area, I always had a soft spot for the Voyagers (which were sent in reverse order first Voyager 2 then 1) just shy of my 17th birthday (As I recall, I skipped school that day for Voyager 1 but not 2) so I was able to drive on my own to go watch them in Titusville. I never dreamed they would last this long.

    When I worked at JPL I recall reading that the Voyager instrument computer packages had redundant backup systems. It will be interesting to know how often the FDS #2 and the TMU #2 were used in the past. Also, the power output from the RTGs has been reduced to try and prolong the flight for as long as possible... maybe boost the power to the thermal blanket to see if the extra warmth will help the FDS recover.

    Oh, your last point made is something I don't need to prepare for. I have expected the Voyagers to die for a decade, now. They have outperformed their intended lifespan by such an ASTOUNDING degree that we cannot possibly be disappointed in them, no matter how short their remaining time is, at this point! And... by what clues you gave, I can safely say you are 5 years younger than I am, LOL! So I remember all of those points in each Voyager's missions with great clarity, too, and was old enough when they first took off to have magazines (Omni is one, and one I still miss - RIP Omni) detailing their whole mission, step by step. I remember them giving the present day's dates for them crossing beyond each point over and above their planned missions, when they fully expected that the Voyager pair would now only be carrying those famous records with our information on them out to the void, and be unable to tell us anything at all. And here we are, still getting communications from them‽ Amazing!

    I was on the Voyager mission control team for 3 of the 4 encounters. DSE was the data systems engineer and one of my systems was the FDS. I have to admit at 77, I can't remember much about the system. But I know it was designed using very old tech, had a custom-designed computer because there were no micro-computers at that time. In fact, The 1st microchip was in 1971 and Voyager was mostly finished design by then and probably in production by then. It is kind of thrilling to me that the Voyagers are still returning important scientific data. JPL has repaired many S/C over the years that seemed impossible to fix. For example, look up Galileo Spacecraft Antenna for a really interesting problem/solution. I was a mission controller (ACE) on the extended mission.

    I follow with interest your work, lectures, and interviews. You have informed inspired me. my heartfelt thanks. With indulgence, ive a few but two questions: dark energy the resultant increase in the rate of expansion ? of the universe is actually the result of the cumulative, compounding and evolving emissions of all cosmic objects along with the compounding number of gravitational waves snapping on space/time pushing it further out radially? For this to be possible, the universe must be expanding at different rates in different locations due to the amount of mass capable of emitting energy in that location, like wind on a sail. Measured on a scale of 13.8 billion years. More raindrops may cause a flood to rage faster in areas of more moving mass. Do the interaction of constantly produced nuetrinos create space time and therefore explain the expansion of the universe, and the increasing complexity of the universes cosmic objects and therefore emitters of nutrinos, account for the current increase in the speed of expansion that is observed? The universe began as a seed that was cast into a reactive medium and we are growing. What if particles or molecules emit a hum the frequency and therefore density of which has variability based on , and that chorus of the local particles is what we call space/time that is being emitted. The magnetism of the interaction binds the particles which continue to hum, emitting space time. Larger concentrations of spacetime are dark matter. Big bang nucleosynthesis. Alpha Beta Gama Paper. Get it. What emits nutrinos? If the emission of nutrinos that together create resonance that cumulatively affect the mass emitting it, small variations in the number of emitters would expand space time more in those areas pushing the emitters closer together and in a domino effect this artifice would be formed into filaments and bulges, which is what we see. Is gravity the resonance created by the strength of the magnetism of the mass. And the outward flow of the the neutrino field the “pressure” that locks the hum of the mass into a distance or location that is held in tension between magnetism and the neurtrinos hold.

    Do the Voyagers have an onboard battery that can charge up on power from the RTG, even if it has to take a very very long time to do so with the diminishing rate, and then send communications back periodically? If they do have them, is the power level dropping so much that even this is not possible?

    So, if Cassiopeia A's supernova explosion had a light delay so that it did not reach us until around A.D. 1600, that means that the ancient astronomers, particularly the Greeks who described and named this constellation, saw something different! Now, I still do not see a lady in a chair, even with a star there, but it reminds to not look at the sky as it now is, but instead as it was a few thousand years ago, in order to try to make sense of the constellation names.

    Do the Voyagers have a mechanism to charge their batteries over a long period of time, then turn on only to make measurements and send them back home before the battery runs out? It could be a fixed time period, so ground antennas would know when to listen. Are they in this mode already and even that is running out of power?

There would be absolutely nothing we could do about it, and every generation for thousands of years would live their lives fearing it would happen during their lifetime. Makes me wonder how many civilizations of beings in our [possibly] infinite universe have had to actually live through such a reality.

    Do you mean solar plane rather than galactic plane? Both Voyagers are still well within the solar system*. They have managed only fraction of the way to the inner edge of the Oort Cloud. And both Voyagers are not travelling along the solar plane any more. Voyager 1 went up at a steep angle after encountering Saturn, Voyager 2 went down at a steep angle after encountering Neptune. * you may have heard that the Voyagers have left the solar system. No, the have exited the heliosphere (the area reached by the solar wind) and they have left the orbits of all the known planets (and Pluto) behind. But they are still far within the gravitational influence of the sun. Voyager 1 is about 162 AU from the Sun, the Oort Cloud is around 2,000-100,000 AU from the sun.

    I don't know the exact cause of the failures, but it's a mechanical device and such things just break down over time. Lubricants leak and evaporate, or become slowly contaminated. Friction wears on the joints and axles. Metal/material fatigue could be the issue even for long lived systems...etc.

    @@abrahamroloff8671 Thanks for the answer. However, I am a little more curious about the specifics here. There are an awful lot of mechanical parts involved in a space telescopes like Hubble, but what was breaking down, were plenty of redundant gyroscopes from more than one production line. That is a specific problem with a specific kind of equipment and not one of all mechanical parts. And that specific problem was either solved since the last installations of the technology on Hubble or not and if not, thet same problems will occure on more spacecrafts - unless the whole technology was replaced by something completely different.

    I assume they replaced them with laser ring gyros but maybe not, space is a conservative business. One cause of failure on momentum wheels on a few other satellites was that static electricity would cause a spark between the race and balls on the ball bearings and over time the friction increased. The solution to that was ceramic balls.

    I've been saying the same about whales and dolphins for years, so this is very heartening to me. Cetaceans are our biological cousins that evolved in the same conditions we did, so if we can't communicate with them, then I think we should be ready for failure talking to interstellar aliens. What I will add to what you said is that we needn't worry about the round-trip communication time. Once we make 2-way contact, each side should begin sending a constant stream of data. So we can respond to what we're getting as soon as we've decided what to say, at every moment. The worst that happens is that some of our questions get answered before the aliens could respond to them, and that's fine.
