#Voyager1

47 years, and keeps going where no man has gone before.

A fuel tube inside the thrusters has become clogged with silicon dioxide, a byproduct that appears with age from a rubber diaphragm in the spacecraft’s fuel tank. The clogging reduces how efficiently the thrusters can generate force. After weeks of careful planning, the team switched the spacecraft to a different set of thrusters.

And, all this happens 22.83 light-hours away from Terra 😲
