Voyager spacecraft going strong at age 33Baltimore, Ohio (UPI) Jan 17, 2011 NASA's twin Voyager spacecraft, approaching the edge of the solar system, are still operating and sending back data 33 years after their launch, scientists say. And they are still making news, as researchers announced last month Voyager 1 had outrun the solar wind, the first man-made object to reach the threshold of interstellar space, The Baltimore Sun reported Monday. It's a performance that impresses even Stamatios "Tom" Krimigis of the Johns Hopkins University's Applied Physics Lab, ... read more |
