The story so far
Voyager 2 is losing approximately 4 watts of power annually as its plutonium source fades. To mitigate this decline, NASA engineers executed a system swap, referred to as the “Big Bang,” to preserve the probe's remaining energy.
This maneuver functions as a power diet, allowing the spacecraft to continue collecting scientific data despite its advanced age and diminishing fuel reserves. Coverage from SciTechDaily and Space Daily notes that this action successfully secures at least one additional year of mission life for the probe.
The mission continues to operate in deep space as it nears its five-decade milestone. While the adjustment provides a temporary extension for scientific observations, coverage does not yet specify the long-term sustainability of the power-saving measures or the specific date when instrument operations must eventually cease.

The obvious questions
What is the 'Big Bang' procedure?
It is an all-at-once power-system swap performed by engineers to manage the declining output of the spacecraft's plutonium source.
How much power is Voyager 2 losing?
The spacecraft is losing approximately 4 watts of power every year.
How long will this extension last?
NASA has secured at least one additional year of science operations.
