How NASA is Hacking Voyager 1 Back to Life

Engineers found space in the geriatric spacecraft’s memory to deal with a stuck bit

On 14 November 2023, NASA’s interstellar space probe Voyager 1 began sending gibberish back to Earth. For five months, the spacecraft transmitted unusable data equivalent to a dial tone.

In March, engineers discovered the cause of the communication snafu: a stuck bit in one of the chips comprising part of Voyager’s onboard memory. The chip contained lines of code used by the flight data subsystem (FDS), one of three computers aboard the spacecraft and the one that is responsible for collecting and packaging data before sending it back to Earth.
