NASA Shuts Off Instrument on Voyager 1 to Extend Interstellar Mission
NASA engineers at Jet Propulsion Laboratory deactivated the Low-energy Charged Particles (LECP) instrument on Voyager 1 on April 17, 2026, to conserve power. This decision follows a power drop during a maneuver, ensuring continued operation of the Magnetometer and Plasma Wave Subsystem. The shutdown extends the mission's capabilities into the 2030s, with a planned power management strategy called the Big Bang.
Engineers shut down another instrument on Voyager-1
NASA engineers at Jet Propulsion Laboratory shut down the Low-energy Charged Particles experiment on Voyager 1 on April 17, 2026, due to declining power. This decision follows a pre-established plan to extend the spacecraft's operational life. Voyager 1 now has three active instruments, with hopes to last until 2027, marking its fiftieth anniversary in space.
NASA Shuts Off Instrument on Voyager 1 to Keep Spacecraft Operating
NASA engineers at Jet Propulsion Laboratory (JPL) commanded the shutdown of the Low-energy Charged Particles (LECP) experiment on Voyager 1 on April 17 to conserve power. This decision follows a pre-established plan to maintain mission operations, having already deactivated seven of ten instruments. The LECP has provided critical interstellar data since Voyager 1's 1977 launch.
