The space agency reported Voyager 1 recently turned off one of its two radio transmitters, and the team is currently working to figure out what caused it.

NASA lost contact with the interstellar Voyager 1 spacecraft for nearly a week after a technical glitch shut off the probe's main transmitter. Using Voyager's weaker backup transmitter, engineers are assessing the problem from 15 billion miles away.

Nasa successfully re-established communication with the Voyager 1 spacecraft on October 24 after a brief pause due to a fault protection system activation.

Voyagers 1 and 2 have been flying for more than 47 years and are the only two spacecraft to operate in interstellar space

The Voyager 1 switched off its transmitters triggered by its fault protection system.
