NASA’s Voyager 1 Resumes Transmission After Communication Glitch

NASA’s Voyager 1 probe, the most distant man-made object in the universe, recently resumed sending usable data to ground control after experiencing communication issues.

Communication Issue

  • On November 14, 2023, Voyager 1 stopped transmitting readable data to Earth while still receiving commands.
  • This posed a challenge for ground controllers.


  • In March, NASA’s Jet Propulsion Laboratory identified a malfunctioning chip as the cause of the communication problem.
  • Engineers developed a coding fix to address the issue, accommodating the spacecraft’s aging computer system’s memory constraints.

Current Status

  • Voyager 1 is now transmitting data regarding the health and status of its engineering systems.
  • Efforts are underway to restore the transmission of scientific data.

Voyager 1 Mission Overview

  • Launched in 1977, Voyager 1 became the first human-made spacecraft to enter the interstellar medium in 2012.
  • It is currently over 15 billion miles away from Earth.
  • Voyager 2, its twin, also exited the solar system in 2018.

Golden Records

  • Both Voyager spacecraft carry Golden Records, 12-inch gold-plated copper disks containing information about Earth.
  • These records were designed to communicate with extraterrestrial life and contain a variety of content, including a map of the solar system, encoded images, music, and sounds.

Future Prospects

  • Voyager 1’s power banks are expected to deplete around 2025.
  • Afterward, it will continue its journey through the Milky Way, potentially indefinitely.
