I remember these in the late seventies when I was in High School. Ok I am old! What is amazing they are still working thou Voyager 1 has computer problems. The below is from interestingengineering.com written by Deena Theresa:
"The 45-year-old probe is aging gracefully.
Since May, the engineering team with NASA's Voyager 1 spacecraft had been trying to solve a mystery. The 45-year-old spacecraft seemed to be in excellent condition, receiving and executing commands from Earth, along with gathering and returning science data - but the probe's attitude articulation and control system (AACS) was sending garbled information about its health and activities to mission controllers.
The AACS controls the spacecraft's orientation and keeps Voyager 1's high-gain antenna pointed precisely at Earth, enabling it to send data home. Though all signs suggested that the AACS was still working, the telemetry data was invalid. For instance, the data appeared to be randomly generated or did not reflect any possible state the AACS could be in.
However, in today's dose of good news, NASA reported that engineers had located the source of the junk data: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.
A bad command from another onboard computer
Suzanne Dodd, Voyager’s project manager, said that when they suspected this was the issue, they opted to try a low-risk solution: commanding the AACS to resume sending the data to the correct computer.
The solution was low-risk but time-consuming. A radio signal takes nearly 22 hours to reach Voyager 1, which was 14.6 billion miles (23.5 billion kilometers) from Earth and growing farther by the second as of August 30.
While the problem has been solved, the team is uncertain why it occurred in the first place.
They suspect the interstellar explorer began routing its health and status telemetry through the dead computer after receiving a bad command from yet another onboard computer. That would suggest that some other problem lurked inside Voyager 1's computer brains. But, the mission managers don't think it threatens the spacecraft's long-term health.
Yet to probe the root cause
"We're happy to have the telemetry back," Dodd said in a statement. "We'll do a full memory readout of the AACS and look at everything it's been doing. That will help us try to diagnose the problem that caused the telemetry issue in the first place."
Nevertheless, they would like to know the source of the mystery.
"So we’re cautiously optimistic, but we still have more investigating to do," she added.
NASA launched the Voyager 1 spacecraft and its twin Voyager 2, in 1977, as part of the NASA Heliophysics System Observatory. The probes were on a mission to explore the solar system's outer planets. Both Voyagers have operated far longer than mission planners expected and are the only spacecraft to collect data in interstellar space, the region outside the heliopause, or the bubble of energetic particles and magnetic fields from the Sun. While Voyager 1 flew by Jupiter and Saturn during its primary mission and entered interstellar space in 2012, Voyager 2 reached the milestone in 2018.
The information the probes provide from this region has helped provide a deeper understanding of the heliosphere, the diffuse barrier the Sun creates around the planets in our solar system.
A division of Caltech in Pasadena, JPL, built and operates the Voyager spacecraft."
There you have it! We may be still getting interstellar information for years to come from the Voyager's. Too bad they do not make them like these anymore. I shell call them the Energizer Bunnies from Earth. They take a licken and keep on ticking. I hope you enjoyed today's interesting fact as much as I did.

I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP
The Defense Intelligence Agency has recently released a large number of documents to different news outlets and individuals who have filed Freedom of Information Act requests.
Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
