NASA engineers fixed Voyager 1's thruster problem by remotely reactivating a set of "dead" roll thrusters that hadn't worked since 2004, which they did by turning on their heater circuits to warm them up and get them working again. 

This creative move was crucial because the backup thrusters Voyager X had relied on were starting to clog, and without working roll thrusters, the spacecraft would lose its ability to point its antenna at Earth and communicate, so the team had to act fast before a long communications blackout made repairs impossible.
