Voyager probes to leave solar system by 2016
Twin spacecraft about to 'get outside of our bubble,' says scientist
NASA's twin unmanned Voyager spacecraft, which were launched in 1977, are streaking toward the edge of the solar system at around 37,000 mph. At that rate, they'll probably pop out of our sun's sphere of influence and into interstellar space by 2016 or so, according to mission scientists.
OT:
I still wonder if Anti-matter engine would be the best propulsion to go explore outside the solar system.
