Two-day deploy to the stars
NASA Shuts Off Instrument on Voyager 1 to Keep Spacecraft Operating
Internet laughs and cries as NASA ‘unplugs’ Voyager 1 to keep it alive
TLDR: NASA shut off a decades-old sensor on Voyager 1 to save power and extend the mission, with a bigger energy tweak planned next. Commenters mixed awe with nerves, joking about 46-hour “deploys,” marveling it’s nearly a light‑day away, and sharing deep dives — all cheering to keep the space elder alive.
NASA just pulled the plug on a tiny but legendary sensor aboard Voyager 1 to save power — and the internet is having big feelings. The nearly 49-year-old probe’s particle detector (LECP) was turned off to buy about a year of life, and commenters split between misty-eyed nostalgia and gallows humor. One dev nailed the mood with a workplace nightmare: “Imagine deploying your bug fix and having to wait two days to find out if it worked!” Others were dazzled by the distance flex — “Closing in on one light day!” — while a chorus marveled at the sheer endurance: “half a century and still ticking.”
Amid the memes, there’s real stakes: Voyager runs on a fading nuclear “battery,” losing roughly 4 watts a year, so every watt is precious. Commands take about 23 hours to reach it, so NASA acted before an auto-shutdown could bork the probe. They even left a tiny 0.5-watt motor spinning, just in case LECP can be revived. The team’s next move, nicknamed the “Big Bang,” will swap multiple systems at once to squeeze more warmth and science — first on Voyager 2, the safer test subject. For the thread’s overachievers, a deep-dive paper made the rounds. The mood? Protect grandma, keep the music playing, and send data home forever.
Key Points
- •NASA’s JPL shut down Voyager 1’s Low-energy Charged Particles instrument on April 17 to conserve power.
- •Voyager 1 experienced an unexpected power drop during a Feb. 27 roll maneuver, prompting preemptive action to avoid undervoltage protection.
- •Both Voyagers’ RTGs lose about 4 watts per year; seven of ten instruments on each spacecraft have been shut off to manage power.
- •Voyager 1 continues operating two instruments (plasma waves and magnetic fields); LECP on Voyager 2 was shut off in March 2025.
- •Shutting down LECP should provide about a year of margin while engineers prepare a broader “Big Bang” power-saving reconfiguration, to be trialed on Voyager 2 first.
