NASA’s Jet Propulsion Laboratory (JPL) has confirmed that Voyager 1 remains in good health.
One of the chips within the FDS is not functioning, NASA engineers have now discovered.
This chip stores a portion of the FDS memory, including some of the system’s software code.

However, NASA cannot physically replace it in outer space, billions of kilometers away.
The US space agency has devised a plan to relocate the aforementioned code elsewhere within the FDS system.
