But it’s presented its team with what NASA is calling a “mystery.”

It’s operating normally but sending back some weird telemetry data.

Voyager 1 is roughly 14.5 billion miles (23.3 billion kilometers) away from home.

This leaves NASA with a whole lot of unknowns.

Is the AACS the culprit or is another system experiencing a glitch?

Will Voyager 1 be able to continue its science mission?

There are ways forward from this glitch.

Voyager 1 may just live with it.

Or a software fix or a switch to backup hardware could be the solution.

NASA hopes both Voyagers will continue to send back science data beyond 2025.
