's finished successfully resetting the computer system of the Voyager 2 satellite, which had begun transmitting unintelligible data in mid-April. The Voyager 2 was launched in August of 1977 to study Saturn, and has also flown past Jupiter, Uranus and Neptune. It's now around 8.6 billion miles from earth, in the heliosphere which surrounds the solar system. While the cause of the glitch is unknown, NASA officials say that they noticed on May 12th that a single memory location had been changed from a 0 to a 1, causing all transmissions to be completely garbled. After the reset, Voyager 2 resumed transmission of data on May 22nd -- and continues its journey to leave the solar system entirely.
