NASA’s New Horizons woke from a nearly yearlong hibernation about 6 billion miles from Earth and is expected to operate into the 2050s, studying how the solar wind slows as it moves through the Kuiper Belt and planning one more flyby with Rubin Observatory help. Measurements show solar wind is about 13-15% slower at the edge than near Earth.
NASA's Voyager 1 is set to reach a distance of one light-day from Earth on November 18, 2026, making it the farthest human-made object and highlighting nearly 50 years of deep-space exploration; Voyager 2 remains active in interstellar space with a shrinking instrument suite, hundreds of times farther from Earth, and both missions continue to transmit data as power wanes, offering unique insights into the solar system's boundary and beyond.
Voyager 2’s 1986 and 1989 flybys gave the first close look at Uranus and Neptune, but no orbiter has followed to study them over time. Key questions about their interiors, the peculiar tilted and offset magnetic fields, and the small, elusive rings and moons remain, in part because a flyby captures only a moment. A future Uranus Orbiter and Probe could map gravity and magnetism, monitor atmospheres, and test for subsurface oceans, advancing our understanding of ice giants and informing exoplanet science.
NASA plans a risky “Big Bang” engineering move on Voyager 2 in May–June 2026 to swap which devices stay powered (turning off heater-related lines, turning on others) to save about 10 watts and extend the probes’ operations. If successful, Voyager 1 would undergo the same adjustment later that summer. With roughly 230 watts left for systems and a transmitter around 200 watts, the twin spacecraft—launched in 1977 and now in interstellar space (V1 since 2012, V2 since 2018)—could keep returning science into the 2030s, potentially reaching around 200 astronomical units, though power will keep dwindling and some instruments may be shut down.
Voyager 1 and Voyager 2, launched in 1977, are nearing the end of their missions as decaying Plutonium-238 power forces NASA to shut down instruments; yet after almost five decades they’ve delivered unprecedented data from the outer planets and now interstellar space, and NASA hopes to extend their lives into the 2030s while newer observatories—Rubin Observatory, James Webb, Hubble, and the upcoming Roman Space Telescope—carry the torch of cosmic exploration.
New analysis suggests Voyager 2 encountered Uranus during a solar wind event—likely a co-rotating interaction region—raising Uranus’ radiation belts and solving the long-standing mystery of the intense radiation Voyager 2 saw.
NASA's Voyager probes have crossed the solar system's boundary, the heliopause, and discovered a mysterious 'firewall' region with extreme temperatures and unexpected magnetic field alignments, revealing new insights into the solar system's edge and our cosmic environment.
NASA is celebrating the 48th anniversary of the Voyager spacecraft missions by sharing an archive video of a 1990 press conference, highlighting the spacecraft's historic journey and the iconic 'Pale Blue Dot' image, with hopes that both will soon reach their 50th launch day and continue their journey into interstellar space.
Voyager 2, traveling at 55,000 km/h, would take over 100,000 years to reach Sirius, the closest bright star at 8.6 light years away, and by then it would be a silent, inactive relic of human technology, highlighting the immense timescales involved in interstellar travel.
If Voyager 2 were pulled into a new star system, its trajectory could be altered, potentially capturing it into orbit around a star, interacting with planets, or even colliding with celestial objects. It could also serve as a long-term artifact and a potential interstellar archive, providing valuable data and a lasting human legacy among alien worlds.
In about four billion years, the Milky Way will merge with the Andromeda galaxy, and while Voyager 1 and 2 will drift in interstellar space long after their power supplies fail, their survival through the collision is uncertain, with risks from stellar encounters, interstellar dust, gravitational deflections, and structural degradation, though they may persist as scattered remnants or debris, symbolizing humanity's first interstellar artifacts.
The article humorously speculates whether astronomers in the year 3025 will detect echoes or signals from NASA's Voyager 1 and 2 spacecraft, highlighting the long-term legacy of these missions and the distant future of space exploration.
Voyager 2's crossing into interstellar space has revealed unexpected findings about the heliosphere's structure, magnetic field alignment, and cosmic ray behavior, raising new questions about the nature of our solar system's boundary and its future evolution.
Voyager 2, launched in 1977, continues to explore interstellar space thanks to advanced engineering, including durable instruments, nuclear power sources, and precise thrusters, making it one of the most enduring spacecraft in history.
Voyager 2's 1979 flyby provided the first detailed study of Jupiter's Great Red Spot, revealing its massive size, dynamic structure, and longevity, which continues to challenge our understanding of planetary storms, although its size and appearance are still changing today.
