Voyager Probes Mark 49-Year Odyssey Beyond the Solar System

NASA’s Voyager 1 and Voyager 2, launched in 1977, continue their historic mission far past its four-year plan, visiting all four outer planets and now venturing in interstellar space while sending data back to Earth. Even as aging power limits require hardware tweaks to extend life, the probes remain functional and keep delivering space measurements, carrying the Golden Record and providing the famous 1990 pale blue dot Earth image as they drift farther from home.

Webb Discovers Uranus’s 29th Moon, a Tiny 10-km World Voyager 2 Missed

The James Webb Space Telescope found a new Uranian moon, S/2025 U1, about 10 kilometers across, between Ophelia and Bianca, bringing Uranus’s known moons to 29. Voyager 2’s 1986 flyby had already discovered 10 moons (with Perdita later identified in archival data), but its brief, changing view and instrumental limits mean it could miss small objects like this. Webb’s six-hour infrared observations confirmed the moon’s movement, and its proximity to rings and inner moons offers new data for modeling Uranus’s system. The discovery highlights how different observing methods reveal unseen bodies and how future missions could further illuminate the Uranian system.

NASA's Big Bang power move buys Voyager 2 another year

NASA engineers have extended Voyager 2’s mission by reallocating power from nonessential systems to preserve the craft’s three remaining instruments, using a carefully balanced power-saving maneuver called the Big Bang. The reallocation should keep the instruments operating for at least another year despite shrinking RTG power. Voyager 2 is now about 13.2 billion miles from Earth, with communications taking roughly 20 hours one way, and NASA plans to apply a similar strategy to Voyager 1.

Voyager 2 Survives on a Big Bang Power Swap, Extending its Interstellar Mission

NASA performed a coordinated 'Big Bang' power-and-thermal swap on Voyager 2, freeing almost 10 watts to keep its three active instruments on for at least a year despite ~4 watts/year decline from the RTGs at 143 AU. It’s not a repair, but a load reallocation to manage heat and power on a spacecraft with razor-thin margins, no repair port, and no spare parts. The rearrangement preserves the magnetometer, plasma-wave subsystem, and cosmic-ray instrument, with Voyager 1 slated for a similar reconfiguration and the possibility of continued operation into the 2030s if conditions hold.

Voyager 2 Extends Mission Life With a Bold 'Big Bang' Power Shuffle

NASA's Voyager 2 gained about two extra years of life by a bold, 'Big Bang' power-and-thermal reconfiguration that flips multiple subsystems on at once to conserve power while keeping heaters warm. After Earth tests and telemetry validation, the permanent change was deployed on July 9; the next instrument shutdown (Cosmic Ray System) has been postponed to after Voyager 2's 50th anniversary in 2027 and into 2028. Margins are tight and subject to revision, and engineers may consider reactivating some instruments if funding allows; a similar update could be explored for Voyager 1.

NASA Reboots Voyager 2 from 13 Billion Miles Away with 'Big Bang' Software Update

NASA beamed a new software update—nicknamed 'Big Bang'—to Voyager 2 from about 13.3 billion miles away, turning off some high‑power devices and swapping them for lower‑power options to conserve energy. The change should keep the remaining three instruments operational for at least another year as the RTG power slowly declines, and NASA plans to apply the same update to Voyager 1.

NASA Extends Voyager 2's Mission With a Power-Saving Tune-Up

NASA has extended Voyager 2’s lifespan by about one year using a software update nicknamed “Big Bang.” By turning off certain high-power instruments and swapping in lower-power equivalents, the spacecraft conserves the dwindling power from its plutonium RTG (losing roughly 4 watts per year), allowing its three remaining instruments to continue science work roughly 13 billion miles from Earth. Voyager 2, launched in 1977, visited the outer planets, reached interstellar space in 2018, and now transmits data about the heliosphere as its energy budget tightens.

Voyager 1 Gets a Lifeline: NASA Tests Power-Saving Swap on Dying Probe

NASA is testing a ‘Big Bang’ style power-swap on Voyager 1 to extend its life by turning off several aging loads and swapping in lower-power components, following a successful upgrade on Voyager 2. Voyager 1 now has only two instruments left (magnetometer and plasma wave) and sits farther away than Voyager 2, about 25 billion km vs. 21 billion km. If the thermal test is successful, the change could free enough power to potentially re-enable the Low-energy Charged Particles instrument; however, the plan remains cautious since commands take roughly a day to reach Earth and back.

Voyager 2 Stretches Interstellar Lifespan With Grounded Power Swap

Voyager 2 Stretches Interstellar Lifespan With Grounded Power Swap

NASA’s Voyager 2 gained at least a year of extra operational life not by touching the spacecraft, but via a coordinated ground-based power swap called the “Big Bang” that swaps in lower-power components while keeping critical heaters and instruments online. With a roughly 39-hour command cycle (about 19.5 hours to reach the probe and the same back), engineers plan far in advance, since there’s no live troubleshooting. The change reduces power demand from aging RTGs and preserves science measurements from three active instruments in interstellar space; Voyager 1 will receive a similar upgrade in the coming months.

Voyager 2’s 176-Year Grand Tour: a gravity-powered sprint through the outer giants

Launched in 1977, Voyager 2 was timed to a rare 176-year planetary alignment that let it visit Jupiter, Saturn, Uranus and Neptune via gravity assists—carrying no propellant for the long legs and extending its life to study all four giants. The route, planned by JPL using gravity‑assist principles, remains the only mission to visit Uranus and Neptune, with the next comparable window not expected until the 2150s. Gravity assists continue to enable modern missions, while each encounter shaped what we know about the outer planets.

Voyager 2’s Uranus Flyby: A Rare 4% Moment That Shaped Planetary Science

A 2024 reanalysis argues Voyager 2’s 1986 Uranus flyby occurred during an exceptionally compressed solar wind—an event estimated to happen only about 4% of the time—reframing the encounter as a rare snapshot that may explain Uranus’s unusual magnetosphere and radiation belts, and underscoring the need for multi-year orbital observations rather than a single flyby.

Voyager 2 nails Neptune flyby with golf-putt precision

After a 12-year, 7.13-billion-km journey, Voyager 2 arrived at Neptune within 100 km of its planned point—a margin NASA likens to a golf-putt 3,630 km long—thanks to gravity assists and precise tracking; the flyby passed 29,240 km from Neptune’s centre and about 4,950 km above its north pole, and revealed six new moons, four rings, and Triton’s geysers, making it the only close Neptune visit to date and fueling discussion of future ice-giant missions.

NASA’s Voyager 2 Big Bang power save buys more life; Voyager 1 to follow

NASA’s Big Bang power-saving maneuver on Voyager 2, which temporarily shuts off high-power instruments in favor of lower-power ones, should extend its science operations by about a year. Voyager 1, currently in worse shape for power, is slated for a similar energy-saving move in the coming months as both probes head toward their 50th anniversaries (launched in 1977).
