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.govShort answer: There is no fixed date for Voyager 1 to “die.” Its power is fading, and mission teams have been turning off instruments to extend life, with a likely end of operational data in the 2030s to mid-2030s range, depending on power and subsystem failures.[3][5][8]
What’s happening now
- Voyager 1 is running on diminishing electrical power, and NASA has periodically shut down nonessential instruments to extend the mission.[8][3]
- The goal is to keep sending back data as long as possible, potentially into the late 2020s or early 2030s, but exact timing is uncertain because it depends on power, component health, and how aggressively power-saving measures are applied.[9][3]
Important context
- The spacecraft remains the most distant human-made object and still transmits occasionally, but with very limited science return as power drops.[7][3]
- Official guidance from NASA emphasizes extending mission life rather than predicting a precise “end,” since several systems could fail at unknown times.[5]
Illustrative note
- A practical way to think about it: Voyager 1 is like a far-off lighthouse gradually dimming over years; engineers can keep the light on longer by reducing how much energy each function uses, but eventually the power will be too low to communicate even a weak signal.[3][8]
