Voyagers (Oort/Kuiper)
Dec 23^rd, 2018 at 5:37pm

Been watching quite a few clips on the travels of the Voyager probes.
One thing that stood out is the mention of them going through the Kuiper Belt a while ago and now how Voyager 1 is in the zone of the Oort Cloud (The Solar Bubble) where it is 10 years travel time thick before it emerges out into the 'void' of true Intersteller Space (no longer protected against Gamma Rays, Neutrinos, etc).

With this, and via the probes investigating Comets...

The 'Dirty Snowball' label is pure incorrect MYTH.
Comets and Asteroids are NOT frozen rocks of ice, etc.
Instead - they show geological traits similar to rock/stone formations on Earth. All of which are

'HEAT'

induced and the chemicals on them are are formed from heat.
The majority of Asteroids are also 'Peanut' shaped - meaning its like two asteroids have been 'welded' together via heat.

So looking at the Kuiper Belt - I now offer the hypothesis that it is indeed an EX-PLANET and the

PLANET X

itself... or the 'remains' of such a planet. Destroyed long ago to form a 'Ring' around the sun known as the Kuiper Belt outside the orbit of Neptune (where Pluto almost resides).
Who knows, the Asteroid belt outside of Mars could also be a destroyed ex-planet.

No protection is required from Neutrinos -
they can pass right through the Earth without colliding with anything.
Billions of them pass through us every second
and do us no harm at all.

However in interstellar space there are high energy protons -
much greater energies than the ones at CERN.
They could easily damage modern computers but
Voyager is not so vulnerable with its large semiconductors.

Let's hope not. Would be nice to be around 90 years of age and hear of the Voyager still travelling out there and finding something new and different, if possible.

It will be interesting to see what happens when Voyager does break through the Solar System's limit in the form of the Oort Cloud (the Sun's most external 'protective' barrier).

I don't think the Voyagers will last more than another 5 years at the most.

They can continue as long as Earth keeps sending such signals.

Sorry JaSin -
they don't get recharged from Earth -
they receive their power from a P238 battery
via thermocouples connected in series around it.
The Plutonium gets very hot & that causes each thermocouple
to give off a small voltage.

They are the longest lasting batteries ever made.
Theoretically they could last for centuries but they
are already giving less power than when first installed.
I think it's now about 75% of the original power.

It's 50% not 75% of the original power.

https://www.allaboutcircuits.com/news/voyager-mission-anniversary-rtg-radioisoto...

Summary

Thanks to the radioactive decay of certain elements the Voyager probes continue to operate well beyond their original mission parameters. While the RTGs today only operate at approximately 50% power (due to the decay of almost half the plutonium-238), they are still able to provide power for the transmission of data. By 2020, the onboard instrumentation on the Voyager probes will be turned off one by one in an attempt to conserve power and keep the probes in communication with radio telescopes on Earth. By 2025, there will not be enough power to operate the onboard scientific equipment and thus ending the scientific operation of the Voyager probes.

RTGs provide probes going to the outer solar system with power when solar energy becomes too little and they can provide power for a long time. Until more exotic power generation techniques become available RTGs will still be the favorite for long-term deep space exploration.

I think they were only supposed to go for 10 years so they've had a good innings.
The signals coming back are now so faint that only the largest
radio dishes in the world with the most
up to date cryogenic receivers can receive the signals.
They actually use 2 receiver stations in Australia.

I just hope they make (or at least one of them) it to inter-steller space before they are gone from us forever. Anyway - their travels have been the best running TV series of all time, in my view.

Not a bad idea. Everything successful has a 'back up' plan.

Do you actually have any evidence for this?

Yes - there are numerous Youtubes on the subject, all based upon probes taking samples from Comets & Asteroids, etc. Unless they have been faked by Hollywood too?
