“As both Voyager probes experience new trials, mission team members have only the original manuals written decades ago to consult”
Voyager 1’s flight data system has been sending back a repeating pattern of ones and zeroes since November 14. The probe still takes commands, but no science or engineering data comes home. Every fix takes 22.5 hours to arrive and 45 hours to confirm, and the last similar fault was in 1981. The probe was built to last five years. The team is debugging year 46 with the original manuals.
