JPL engineers have successfully reconfigured a power management switch on the Voyager 2 spacecraft in deep space, freeing up enough electrical margin to keep the probe operational for an extra year, according to technical details obtained by The Register from a NASA spokesperson. The intervention involved a switch involving two heaters and another device that was kept on to provide sufficient heat to the spacecraft to allow it to keep functioning.
How the Voyager 2 ‘Big Bang’ Power Switch Works
Operating in the vacuum of space means spacecraft radiate heat away. According to The Register's reporting on the official NASA statements, these heaters do more than maintain safe operating temperatures for the onboard electronics. They also keep the fuel lines warm, ensuring the probe retains the capacity to perform attitude adjustments.
Extending Interstellar Exploration Limits
Voyager spacecraft draw their power from Radioisotope Thermoelectric Generators (RTGs). As this power supply diminishes, mission operators must make choices to shed electrical load. By successfully executing this power reconfiguration on Voyager 2, the JPL team has bought the mission an extra year on its extended timeline. Project engineers now plan to perform the same switch on Voyager 1, which faces similar energy constraints before both probes eventually fall silent in deep space.
Did you know? Voyager 2 is an irreplaceable space probe operating in deep space.
Frequently Asked Questions
Why is Voyager 2 losing power?
Voyager 2 is powered by a Radioisotope Thermoelectric Generator (RTG) and is experiencing rapidly diminishing power.
What did the JPL engineers change on the spacecraft?
According to The Register, engineers utilized a switch to reroute power from two heaters and another device that was previously kept running continuously, freeing up sufficient energy to keep the electronics within a happy operating range and warm fuel lines.
Will Voyager 1 get the same power adjustment?
Yes, the JPL team hopes to perform the same switch on Voyager 1 soon to provide a similar boost to its expected lifespan before both spacecraft eventually go quiet.
