Voyager 1 - NASA Science
No spacecraft has gone farther than NASA's Voyager 1. Launched in 1977 to fly by Jupiter and Saturn, Voyager 1 crossed into interstellar space in August 2012.
science.nasa.govHere’s the latest on Voyager 1 based on recent reliable reporting:
-
Voyager 1 briefly went quiet in late 2023 due to power and data handling issues but was restored and fully back online by mid-2024. NASA and Space.com reported that after a software fix, the probe resumed health monitoring and gradually re-enabled its instruments, with full science data return by June 2024. NASA’s JPL confirmed the engineering data resumed after relocation of flight data subsystem code and subsequent health checks in April 2024.[2][4][6]
-
As of early 2026, Voyager 1 remains the most distant human-made object and continues to send engineering data and limited science data as power allows. NASA Science notes Voyager 1 is in interstellar space, having crossed the heliopause in 2012, with ongoing, though reduced, data transmission capabilities due to aging systems. Ongoing mission management focuses on preserving power, relocating electronics when needed, and maintaining communications with Earth over very long light-time delays (around 21–23 hours one-way).[7]
-
Notable context: ongoing public-interest stories emphasize the aging power supply and how it constrains the rate and scope of data transmission. Major outlets described the challenges and NASA’s planning to extend the mission as long as possible, given energy constraints and instrument health.[5][9]
Key takeaways:
- Voyager 1 is back online after a multi-month communications gap in 2023–2024 and has resumed health monitoring and partial science data transmission.[4][2]
- It continues to operate in interstellar space, far beyond Neptune, with power limitations affecting data transmission rates and instrument availability.[7]
- NASA aims to maximize mission longevity through software fixes, power management, and careful commissioning of instruments as power allows.[6][2]
