Is the Voyager 1 spacecraft in interstellar space? NASA says yes, but a small but respected community of researchers isn’t convinced.
A quick review of the facts: Last year, NASA scientists penned a research paper that concluded the spacecraft, traveling at 38,000 mph, became the first man-made object to leave the solar system sometime around August 25, 2012.
The article’s authors, who based their announcement on a number of advanced models, stated “after long disagreements, that is now the consensus view of Voyager mission team leaders.”
