NASA has shut down the Low-energy Charged Particles (LECP) instrument on Voyager 1 to conserve power and extend the mission, keeping two other instruments active as the spacecraft—more than 15 billion miles from Earth—drifts through deep space; a 0.5-watt motor on LECP remains running to keep the door open for possible reactivation, while the RTG’s power slowly declines by about 4 watts per year.
NASA has shut down Voyager 1's Low-Energy Charged Particle instrument to conserve dwindling power; only two of its 10 instruments remain powered, while three are active on Voyager 2. A planned 'Big Bang' maneuver would swap several powered devices for lower‑power equivalents to keep the craft warm and continue collecting data. The Big Bang for Voyager 2 is planned for May–June, with a possible July attempt for Voyager 1, a move that could extend the mission by about a year though data return will be limited.
NASA engineers shut down the Low-energy Charged Particles (LECP) instrument on Voyager 1 on April 17 to conserve dwindling nuclear power, allowing the spacecraft to continue studying the interstellar medium beyond the solar system. Voyager 2’s LECP was silenced earlier in 2025, and only a handful of instruments remain active on both Voyagers. Voyager 1 is currently more than 15 billion miles (about 24 billion kilometers) from Earth, making it the farthest human-made object, and the instrument shutdown is part of a planned retirement sequence to maximize science as the power supply declines.
Facing a dwindling nuclear power source, NASA shut down Voyager 1’s Low-energy Charged Particles (LECP) instrument to conserve energy and prevent an automatic shutdown, as its power declines by about four watts per year. Only two instruments remain online—plasma waves and magnetic fields—with a bold plan dubbed the Big Bang to swap in lower‑power components on Voyager 2 first, then Voyager 1, in hopes of keeping the mission alive for at least another year while continuing exploration of interstellar space.
NASA has shut down Voyager 1’s Low-energy Charged Particles instrument to conserve dwindling power as the probe—about 15 billion miles from Earth—continues its interstellar voyage; seven of its ten instrument sets have been turned off so far, with Voyager 2’s LECP already disabled, and the team plans further shutdowns along with a 'Big Bang' power swap to keep data flowing from beyond the heliosphere.
NASA says Voyager 1 — launched in 1977 and the most distant human-made object — is losing about 4 watts of power each year from its plutonium-powered generator. After a dip in energy forced the shutdown of the Low-energy Charged Particles instrument, engineers are pursuing a “far-out plan” to extend the probe’s life as it continues to study interstellar space beyond the heliosphere.
NASA shut down the Low-energy Charged Particles instrument on Voyager 1 to conserve dwindling power, as part of a planned sequence that has already retired seven of ten instrument sets; the move aims to preserve the spacecraft s core systems so it can continue its interstellar voyage, following Voyager 2 s LECP shutdown in March 2025.
