Voyager 1 Beyond Solar Wind 245

healeyb noted that Voyager 1 has now reached a distance from the sun where it is no longer able to detect solar wind. Launched in 1977 to get up close and personal with our solar system's gas giants, scientists estimate that in another 4 years it will cross the heliosphere.

NASA Finds Cause of Voyager 2 Glitch 283

astroengine writes "Earlier this month, engineers suspended Voyager 2's science measurements because of an unexpected problem in its communications stream. A glitch in the flight data system, which formats information for radioing to Earth, was believed to be the problem. Now NASA has found the cause of the issue: it was a single memory bit that had erroneously flipped from a 0 to a 1. The cause of the error is yet to be understood, but NASA plans to reset Voyager's memory tomorrow, clearing the error."

The Ultimate Interstellar Valentine Mix Tape 75

Hugh Pickens writes "NPR reports that toward the end of the summer of 1977, NASA launched two Voyager spacecraft that each included a golden record containing, among other things, the sound of a kiss, a mother's first words to her newborn child, music from all over the world, and greetings in 59 different languages. The records on board were meant to survive for a billion years, in the hope that some day, against enormous odds, they might cross paths with an alien civilization. The record was a special project of Carl Sagan with the help of Ann Druyan, creative director of the project. For Druyan, though, the summer of 1977 and the Voyager project carry a deeply personal meaning because it was during the Voyager project that she and Sagan fell in love. Then Druyan had an idea for the record: They could measure the electrical impulses of a human brain and nervous system, turn it into sound, and put it on the record so that maybe, 1,000 million years from now, some alien civilization might be able to turn that data back into thoughts."
