Submission + - Voyager 1 returns to normal science operations (theregister.com)
wgoodman writes: NASA's Voyager 1 spacecraft is back in action and conducting normal science operations for the first time since the veteran probe began spouting gibberish at the end of 2023.
All four of the spacecraft's remaining operational instruments are now returning usable data to Earth, according to NASA.
Voyager 1's woes began in November 2023, when the spacecraft stopped transmitting usable data back to Earth. Rather than engineering and science data, NASA found itself faced with a repeating pattern of ones and zeroes, as though the spacecraft was somehow stalled.
It appeared that a single chip was malfunctioning, and engineers were faced with the challenge of devising a software update that would work around the defective hardware. Usable engineering data began to be returned later in April, and in May the mission team sent commands to instruct the probe to keep science data flowing. The result was that the plasma wave subsystem and magnetometer instrument began sending data immediately. According to NASA, the cosmic ray subsystem and low energy charged particle instrument required a little more tweaking but are now operational.
