JPL Plans 10-Watt 'Big Bang' to Extend Voyager 1 Into the 2030s

Summary
Voyager 1 could gain years of operating life under a JPL plan to save 10 watts by reconfiguring onboard systems in a single "Big Bang" maneuver.
The change targets a growing power crunch: the probe's radioisotope generators have fallen to about 230 watts from 470 at launch, while heaters for thruster lines compete with science instruments for electricity.
Keeping those thruster lines warm is critical because clogged or frozen lines could stop Voyager 1 from turning its antenna toward Earth, ending contact with the spacecraft.
At 15.85 billion miles away, Voyager 1's signals already take 23 hours to reach Earth; JPL says the power savings could help both Voyager probes keep operating into the 2030s.
With a key deep space antenna offline, can a last-ditch power plan save our farthest messenger?
As Voyager 1’s power fades, is its golden record now its most important mission?

Overview
Voyager 1 has reached a critical point in its journey, facing severe power shortages and aging systems after nearly 50 years in space. To address these challenges, NASA engineers have launched the 'Big Bang' maneuver, a bold strategy to reconfigure the spacecraft’s power distribution. This involves shutting down or reallocating certain components to conserve energy, with hopes of extending Voyager 1’s mission and possibly reactivating key instruments like the LECP. While this maneuver carries significant risks, such as triggering fault protection or losing vital science data, it is essential for keeping Voyager 1 operational and continuing its groundbreaking exploration of interstellar space.
