     BALTIMORE — You probably have more computing power in your pocket than what NASA's venerable Voyager spacecraft are carrying to the edge of the solar system.

They have working memories a million times smaller than your home computer. They record their scientific data on 8-track tape machines. And they communicate with their aging human inventors back home with a 23-watt whisper.

Even so, the twin explorers, now 33 years into their mission, continue to explore new territory as far as 11 billion miles from Earth. And they still make global news. Scientists announced last month that Voyager 1 had outrun the solar wind, the first man-made object to reach the doorstep to interstellar space.
