Voyager 1 Trims Instruments to Stretch Interstellar Mission

NASA's Voyager 1 has shut down the Low-energy Charged Particles instrument to conserve dwindling power from its aging RTGs. The move is part of a broader “Big Bang” plan to power down nonessential systems and keep heaters on, allowing the mission to continue collecting data beyond the heliosphere. Voyager 2 has already shed similar instruments, and planners will test the approach in May–June with the goal of implementing it on Voyager 1 by July, potentially reactivating LECP if more power becomes available.

Voyager 1 pivots to power-saving mode as NASA tests a risky 'Big Bang' to extend life

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.

Voyager 1 Trims Instrument Power as NASA Tests Bold Energy-Saving Plan

NASA shut down Voyager 1’s Low-Energy Charged Particles instrument to conserve dwindling power as it sails through interstellar space about 15 billion miles from Earth, and is pursuing a broader energy-saving fix nicknamed 'Big Bang' to swap in lower-power systems, hoping to buy roughly a year of additional operation while seven of the original ten instruments have been turned off (Voyager 2’s LECP was shut down in 2025). The shutdown sequence takes hours and is driven by distance-related command delays, with one small motor kept active to allow possible future restart.

Power-saving move extends Voyager 1s interstellar journey

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 spacecrafts core systems so it can continue its interstellar voyage, following Voyager 2s LECP shutdown in March 2025.

"Potential End of Communication for NASA's Voyager Spacecraft"

NASA's Voyager 1 and 2, launched in 1977, are on the brink of losing communication with Earth as their power supply dwindles. Despite this, NASA aims to keep in touch with the probes until their 50th anniversary in 2027. The spacecraft, now in interstellar space, have provided invaluable data on charged particles and magnetic fields. Engineers are conserving power by shutting off non-essential systems, but the probes may continue to drift in space for hundreds of thousands of years, carrying golden records meant to communicate with extraterrestrial life.

Heatwave grips central U.S., shattering records and prompting alerts

Sweltering temperatures have brought misery to a large portion of the central United States, with record high temperatures being recorded in Texas and other states. People are being advised to stay hydrated and check on neighbors, while the Electric Reliability Council of Texas has asked residents to voluntarily conserve power due to extreme temperatures and high demand. This heatwave is the latest example of extreme weather events that scientists have warned will become more frequent and prolonged due to climate change. Excessive heat warnings and advisories are in place across several states, with concerns about heat-related illnesses and the impact on outdoor activities and events.

ERCOT and Texas Residents Struggle to Conserve Power Amid Record Heat

ERCOT's voluntary power conservation order, which asked Texans to conserve power from 4 p.m. to 8 p.m. to help prevent rolling blackouts, expired mid-evening Tuesday as the grid held up amid extreme high temperatures. While the grid is not in emergency operations, residents were being asked to reduce electric use if it's safe to do so. If demand outstrips supply, blackouts may occur.
