Voyager 1 Triumphs: Still Exploring After 46 Years
After a weekslong communication blackout caused by Voyager 1’s dwindling power supply and an automatic switch to a weaker transmitter, NASA engineers successfully restored contact. The issue stemmed from a command to activate a heater, triggering a power-saving fault protection system that switched the probe to its less powerful S-band transmitter. Clever problem-solving allowed a return to the X-band transmitter, resuming data collection. This incident highlights the increasing challenges of maintaining the aging probes’ functionality as their power continues to decrease. The team is now working to fully restore the spacecraft’s systems to pre-outage condition.
