NASA engineers trying to figure out strange readings from aging interstellar spacecraft

The engineering team operating the Voyager 1 spacecraft — NASA’s robotic planetary explorer currently zooming through interstellar space — is trying to figure out why the spacecraft is sending back data readouts that don’t match what the vehicle is actually doing. It’s a mystery that does not seem to be putting the Voyager 1 spacecraft in any immediate jeopardy, but NASA is trying to figure it out nonetheless.

Launched in 1977, Voyager 1 has been exploring the cosmos for nearly half a century. It has a twin, Voyager 2, that was launched 16 days prior in the same year.
