If this is correct, all I can say is...

WOW, what an achievement!

Voyager craft "Exits" Solar System


I'm not sure that I agree that it has left the Solar System just yet. According to the article it is 18 billion km out, which sounds a very long way but is actually less than a light-day whereas most astronomers would consider the Oort Cloud to be a part of the Solar system and it extends upwards of a light-year from Sol.

It'll be another 18000 to 20000 years before truly exits the Solar System. (People sometimes don't appreciate just how vast these distances are.)

It's amasing how it is still working after all this time.

NASA Voyager Status Update on Voyager 1 Location


"The Voyager team is aware of reports today that NASA's Voyager 1 has left the solar system," said Edward Stone, Voyager project scientist based at the California Institute of Technology, Pasadena, Calif. "It is the consensus of the Voyager science team that Voyager 1 has not yet left the solar system or reached interstellar space. In December 2012, the Voyager science team reported that Voyager 1 is within a new region called 'the magnetic highway' where energetic particles changed dramatically. A change in the direction of the magnetic field is the last critical indicator of reaching interstellar space and that change of direction has not yet been observed."


When it does leave, will go where no man has ever gone. Exciting!

Kenzie is probably right, but to think that Voyager is still going strong on '70's technology is unbelievable!

What amazes me is the fact that we can still communicate with the damn things! That to me is almost as incredible as the distance they are away from earth.

What about the nitrogen based lifeforms in a long ago episode of Twilight Zone?

Or might have been the other late night 'suppose if you will' series. Can't think of it now.

Geez.

You're probably thinking of "The Outer Limits' The very first episode, starring Cliff Robertson, was entitled 'Galaxy Being'. It was about a humanoid creature from the Andromeda Galaxy, whose life processes were based on a nitrogen cycle, instead of the carbon cycle, as with life on this planet.

Worked at General Electrics Space Center in Valley Forge,PA. We built and tested the RTG's that provide power to the Voyagers. From 100 + Wt peak down to 1 Watt or so today, the RTG's still produce enough juice to allow a weak signal beamed back to earth to be picked up. Most of the systems aboard are inoperative as there's no power for them and the technology (including tape recorders) have long since aged past their utility. The deep space cold permeates the spacecraft and with exception of the receiversand transmitters and the RTG's little heat is present. The ancient vidicon's are also inoperative so no images are possible besides no recorders to store and play back in pieces necessary for transmission.

Perhaps some day we will be able to get out there and catch up to them. Would be something to have a future Probe on its way to a nearby sun stop and pickup the voyager for future museum display...

Anyways it funny to think back to those days and realize the RTG's are so very far away in Space and of course time as well..[/img]

Yes Ed'...that's what I hope will happen one day. No point in leaving them out
there if space technology is such that we can overtake them in space one day.
Bring them back for they have shown themselves to be two technical masterpieces
that deserve a place of honour in a space museum. Not only that but they do hold
valuable information about the survival of technical components, ageing and so
such over long periods of time in outer space.

"By 2025, we will have to turn off the last instrument and that will be the end of the science mission," said Stone, "and the two spacecraft will then forever orbit the center of our galaxy silently."

Orbit the centre of our galaxy? I thought they were heading out into interstellar space in a straight trajectory?

All trajectories are conic sections. (two body anyway)
They don't have galactic escape velocity.
Hyperbola or ellipse?
