NASAs Voyager 1 probe has left the solar system, boldly going where no machine has gone before.
Thirty-six years after it rocketed away from Earth, the plutonium-powered spacecraft has escaped the suns influence and is now cruising 11 1/2 billion miles away in interstellar space, or the vast, cold emptiness between the stars, NASA said Thursday.
And just in case it encounters intelligent life out there, it is carrying a gold-plated, 1970s-era phonograph record with multicultural greetings from Earth, photos and songs, including Chuck Berrys Johnny B. Goode, along with Beethoven, Bach, Mozart and Louis Armstrong.
Never before has a man-made object left the solar system as it is commonly understood.
We made it, said an ecstatic Ed Stone, the missions chief scientist, who waited decades for this moment.

(40,416 posts)Voyager I has the equivalent of 23 watts of power via a Plutonium powered RTG (radioactive thermal generator -- it converts heat to power). It's the same thing that powers the Curiosity Rover on Mars. (Previous Mars rovers were powered by solar which is why they had to shut down at night.)
The fact that two Voyager spacecraft are still going after nearly four decades is, in itself, an astounding feat. Now at a power smaller than the light bulb in your fridge.
Amazing, huh?

(13,360 posts)....is this scene actually from the Star Trek movie Voyager? or is it from a different one? ...either way, I may have to do some "cosmic" movie viewing tonight in honor of the occasion!!!!

(22,308 posts)"Escaped the sun's influence" is a misleading statement. As far as gravity goes, that is impossible.
Voyager 1 has moved past the Heliosphere. That isn't exactly the same as escaping the sun's influence.
Here is a slightly more literate article on the subject (although mixing kilometers and miles per hour makes no sense to me at all).

^snip^
The lonely probe, which is 18.8 billion kms from Earth and hurtling away at 38,000 mph, has long been on the verge of bursting through the heliosphere, a vast, bullet-shaped bubble of particles blown out by the sun. Scientists have spent this year debating whether it had done so, interpreting the data Voyager sent back in different ways.
But now it is official that Voyager 1 passed into the cold, dark and unknown vastness of interstellar space, a place full of dust, plasma and other matter from exploded stars. The article in Science pinpointed a date: August 25, 2012.
"This is the moment we've all been waiting for," Jia-Rui Cook, the media liaison at NASA's Jet Propulsion Laboratory, said. "I can't even sleep it's so exciting!"

(40,416 posts)Bach, Mozart, Indian, Japanese, Islander, jazz, blues, rock (Beatles, Elvis, Chuck Berry, etc.), all sorts of music and sounds is recorded on that record.
So the story goes like this. The SETI project receives the first message from an intelligent extraterrestrial civilization in some time in the future. After many long months of arduous work by the most talented scientists and experts they manage to decode and translate the message. It reads, "Send more Chuck Berry."
Or so the joke goes. My bad. I gave away the punchline.

(80,708 posts)I remember Carl Sagan talking about the album on Cosmos.
I also remember how certain people got mad that the Pioneer probes contained "porn"--- because they contained pictograms of a naked man and woman.
... the more things change, I guess.

On a side note, the stamp, which was issued less than 2 years after the Cuban Revolution, somehow omits Cuba from the map!

More details from NASA here:
"Now that we have new, key data, we believe this is mankind's historic leap into interstellar space," said Ed Stone, Voyager project scientist based at the California Institute of Technology, Pasadena. "The Voyager team needed time to analyze those observations and make sense of them. But we can now answer the question we've all been asking -- 'Are we there yet?' Yes, we are."
