More evidence that Voyager has exited the solar system

Published on October 5th, 2012

Something very, very interesting is happening with Voyager 1, the human probe that’s the very farthest from Earth.

New data from the spacecraft, which I will discuss below, indicate Voyager 1 may have exited the solar system for good. If true, this would mark a truly historic moment for the human race — sending a spacecraft beyond the edge of our home solar system.

At last check, NASA scientists said they were not yet ready to officially declare that Voyager 1 had officially exited the solar system by crossing the heliopause.

To cross this boundary scientists say they would need to observe three things:

1. An increase in high-energy cosmic rays originating from outside our solar system

2. A drop in charged particles emanating from the sun.

3. A change in the direction of the magnetic field.

As I reported in June, in regard to the first point, scientists have observed a sustained increase in galactic cosmic rays during recent months.

With respect to the second point, there has been a dramatic and sustained drop in charged particles (principally protons) originating from the Sun that have struck the spacecraft.

And by dramatic, I mean dramatic. Here’s how it looks:

I have reached out to Edward Stone, the Voyager project scientist based at the California Institute of Technology, who has oversight of the mission. He has not responded to my query about whether this means Voyager has truly exited the system.

The third question is whether the magnetic field affecting Voyager has changed. That data is not yet definitive, said Dave McComas, a heliopause expert with the Southwest Research Institute. “In the end, the magnetometer data will have to tell us if Voyager1 has crossed the heliopause or the disconnection boundary,” McComas told me.

However Nick Suntzeff, a Texas A&M University astronomer, said based upon the stunning drop in charged particles, something is definitely happening to Voyager that NASA should be commenting upon:

“Even without the magnetometer data, the Voyager 1 data shows that it has gone through a huge barrier at the edge of the solar system. These guys are defining it based on their theory which requires a transition zone where the magnetic fields decouple. Maybe this is true. But the fact remains that the satellite has gone through a discontinuity in cosmic ray fluxes that is incredible. It is interacting with the boundary of the Solar System. I think that the data stand on their merit – something wonderful ( a line from the movie 2010) has happened”

Which is to say that NASA may be making an important announcement about Voyager 1 in the not too distant future.

i would be more interested if it was out of our galaxy heading towards a new 1 , look how many years its taken just to get out our boring solar system boring.

more iteresting if they were to put a small probe into space that can be fired to reach light speed sending back data and see how long it would take to get out of our galaxy.

and be nice to send a probe into a black hole with a mega transmitter that could reach us throughout the galaxy , then we can see where it pops out from after going in to a black hole, now thats interesting .

I agree, but then after 100 years of technological expertise, we have only so far managed to see flyby footage of the outer planets (not to mention only recent ground footage of Mars).

At this rate, we'll be seeing the ground robot view of a Neptune moon by 3245......lol

Bon Voyage Voyager, it's amazing.

It is frustrating that we really don't have the technology to send humans to our own moon or even put a base there, the chances of having intergaltic travel or even interstellar travel in our life times are 0. Never less, it is a bit amazing and perhaps even a bit saddening to think of our little bucket of bolts leaving home.
I'm pretty sure it will long surpass our own existence on this planet...

......from NASA......?

The Heliopause (distance unknown) is actully made out of white cheese. :obsessed:

Some will say that the moon is sooooo passe in regards to the secret space program, they have long moved on to bigger and brighter things, albeit tinged with a hint of darkness.
