NASA’s Voyager 1 spacecraft is reviving technology abandoned four decades ago to help keep its groundbreaking space exploration mission alive.
Launched in 1977 shortly after its twin, Voyager 2, the probe has been sending back data that expands our understanding of the cosmos. At its present distance of close to 15.4 billion miles from Earth, Voyager 1 may be nearing the end of its mission, but it’s not ready to to sign off just yet.
Voyager Goes Quiet
On October 16, NASA’s attempt to activate a heater aboard Voyager 1 encountered unexpected issues, leading to several complications. The probe’s heaters are not only used to stave off the cold of space, but also to mitigate radiation damage to essential components. This time, however, the signal to activate the heater triggered Voyager 1’s autonomous fault protection system, which shuts down nonessential systems if they are drawing too much power. Preserving the craft’s dwindling power supply is crucial to extending its mission for as long as possible.
Due to the 23-hour delay for signals to travel between Earth and Voyager 1, the Voyager team didn’t realize something was wrong until October 18. Technicians eventually discovered that the powerful X-band transmitter had stopped sending signals. Later that day, after analyzing the signals, they found a much weaker one, only for it to…
