NASA's venerable Voyager 1 probe has encountered a strange new region at the outer reaches of the solar system, suggesting the spacecraft is poised to pop free into interstellar space, scientists say.

Voyager 1, which has been zooming through space for more than 35 years, observed a dramatic drop in solar particles and a simultaneous big jump in high-energy galactic cosmic rays last August, the scientists announced in three new studies published June 27 in the journal Science.

The probe did not measure a shift in the direction of the ambient magnetic field, indicating that Voyager 1 is still within the sun's sphere of influence, researchers said. But mission scientists think the spacecraft will likely leave Earth's solar system relatively soon.

Voyager 1 and its twin, Voyager 2, launched a few weeks apart in 1977 to study Saturn, Jupiter, Uranus and Neptune. The probes completed this unprecedented "grand tour" and then kept right on flying toward interstellar space.

Voyager 1 should get there first. At 11.5 billion miles from Earth, the spacecraft is the farthest man-made object in space. Voyager 2, for its part, is now 9.4 billion miles from home.

Both probes are currently plying the outer layers of the heliosphere, the enormous bubble of charged particles and magnetic fields surrounding the sun. But things are really getting interesting for Voyager 1, the new studies report.

On Aug. 25, 2012, the probe recorded a 1,000-fold drop in the number of charged solar particles while also measuring a 9 percent increase in fast-moving particles of galactic origin called cosmic rays.

hopefully it's able to actually reach interstellar space before it's fuel runs out in 2025.

^ I thought Voyager would keep on drifting from inertia ...

Wouldn't inertia keep it going?

it should keep going via inertia however, when the fuel runs out we will lose contact with it.

Imagine if this thing has a camera from today's technology on board.

 

Shame they've had to turn so much stuff off to maintain it's fuel.

Kind of makes you think, if you were there to witness it all, the voyage.

 

Question: Do we have any other satellite, with modern tech,  sent out (in recent years) to discover like the Voyager 1 & 2?

New Horizons 

14 Jul 2015 Flyby of PlutoCharonHydraNixS/2011 P 1 and S/2012 P 1 Flyby of Pluto around 11:47 UTC at 13,695 km, 13.78 km/s. Flyby of Charon, Hydra, Nix, S/2011 P 1 and S/2012 P 1 around 12:01 UTC at 29,473 km, 13.87 km/s. [41]  
 
2016–2020 Possible flyby of one or more Kuiper belt objects (KBOs) The probe will perform flybys of other KBOs, if any are in the spacecraft's proximity. [52]  
 
2026 - Expected end of the mission The Dwarf Planets mission will conclude. [53]  
Dec 2038 - New Horizons will be 100 AU from the Sun. If still functioning, the probe will explore the outer heliosphere.

 

So yes, New Horizons i believe is traveling faster than the voyager probes to, because it's getting gravity assist from the gas giants including neptune

hmmm no solar powered anything on board?

I doubt there is enough sunlight to even power an LED that far out :D

What about Solar powered fuel cells that could be used up and then recharged saved for usage once it's outside the range of the sun...  That's what I would have done... *shrug*

Until it gets to the next solar system. :p

Meh.  The Klingon's are just going to blow it up eventually, anyway...
