After greater than forty-six years all of us are more likely to really feel the wear and tear of time, and Voyager 1 isn’t any completely different. Following months of harrowing troubleshooting because the far-flung spacecraft stopped returning smart knowledge, NASA engineers now really feel assured that they’ve tracked down the trigger for the issue: a single faulty reminiscence chip. Why this explicit chip failed is unknown, however potentialities vary from put on and tear to an brisk particle hitting it and disrupting its operation.
We’ve coated the Voyager 1 troubleshooting saga thus far, with the preliminary garbled responses attributed to a spread of programs, however narrowed right down to the Flight Knowledge Subsystem (FDS), which prepares knowledge for transmission by the telemetry modulation unit (TMU). Based mostly on a current ‘poke’ command that returned a reminiscence dump engineers concluded that the roughly 3% of corrupted knowledge match with this one reminiscence chip, opening the potential of a workaround.
Just lately NASA engineers have additionally been engaged on patching up the firmware in each Voyager spacecraft, in opposition to the background of the dwindling vitality produced by the radioisotope mills which have saved each spacecraft powered and heat, even within the chilly, darkish depths of Deep House far past the sunshine of our Solar.
